关于公司股票可能被实施重大违法强制退市的第三次风险提示公告
Delisting Announcement Classification · 90% confidence The document is a formal public announcement by *ST元道 regarding receipt of an administrative notice from the China Securities Regulatory Commission about potential major-violation forced delisting of its shares. It is not a financial report or earnings release but a regulatory notice warning investors of a pending delisting risk. This matches the definition of a Delisting Announcement (DLST).
2026-05-22 Chinese
关于控股股东股份被司法冻结的公告
Regulatory Filings Classification · 68% confidence The document is a formal market announcement from a listed Chinese company regarding the judicial freezing of its controlling shareholder’s shares. It provides courts’ freeze details, share quantities, dates, and legal references. It is not a financial report, earnings release, management change, share issue, dividend notice, or insider transaction. It does not attach substantive financial statements or serve as a management or investor presentation. It also is not primarily a lawsuit update but rather a regulatory disclosure of shareholder share freezes. Therefore, it falls under the general regulatory announcements category (RNS).

股票交易异常波动公告
Regulatory Filings Classification · 85% confidence The document is an exchange‐mandated announcement about abnormal stock trading fluctuations ("股票交易异常波动公告") filed under Shenzhen Stock Exchange rules. It does not contain financial statements or any formal report, but is a regulatory disclosure to investors. There is no indication of dividend, management change, capital raising, M&A, or any other specific filing category. Therefore, it falls under the miscellaneous regulatory announcement category, Regulatory Filings (RNS).

关于持股5%以上股东股份被司法冻结的公告
Legal Proceedings Report Classification · 80% confidence The document is a formal stock exchange announcement in which the issuer discloses that a shareholder holding over 5% of its shares (吴志锋) has had those shares judicially frozen by a court order. This is a legal proceeding affecting significant shareholdings, rather than a pure change of ownership, dividend notice, or financial report. It clearly falls under updates on significant lawsuits or regulatory/legal actions involving the company, fitting the “Legal Proceedings Report” category.

关于子公司部分债务提前到期暨担保进展的公告
Capital/Financing Update Classification · 85% confidence The document is a public announcement by *ST元道 regarding its subsidiary’s debt being declared due early and the status of guarantees, including planned remedies and risk disclosures. It does not present full financial statements or act as an earnings release, nor is it a governance or management report. Instead, it provides an update on the company’s financing situation—specifically debt maturity and guarantees—so it fits the Capital/Financing Update category.
