Filing Released Lang Actions
关于公司取得发明专利证书的公告
Regulatory Filings Classification · 90% confidence The document is an announcement by the company and its board about obtaining a patent certificate from the National Intellectual Property Office. It provides details about the invention, patent number, application and grant dates, and a brief description. This is not financial results, capital changes, voting results, management changes, or any other specific category; it is a general corporate regulatory announcement of a non-financial event. Therefore the correct classification is Regulatory Filings (RNS).

关于筹划重大资产重组的进展公告
M&A Activity Classification · 90% confidence The document is a progress announcement (“关于筹划重大资产重组的进展公告”) detailing a major asset reorganization transaction (cash acquisition of 70% of target company shares) and updates on signing agreements, regulatory inquiries, and next steps. This is not the final proxy or tender‐offer filing itself but an ongoing M&A progress notice. Hence, it fits the M&A Activity category (Code: TAR).
2026-05-29 Chinese
关于公司产品获得IVDR CE认证的公告
Regulatory Filings Classification · 92% confidence The document is an official company announcement regarding two biochemical reagent products obtaining EU IVDR CE certification. This is a regulatory compliance update about product approvals, not a financial report, management change, or capital transaction. It does not contain financial statements or voting results. It fits the “Regulatory Filings” fallback category for general compliance or regulatory announcements.

关于使用闲置自有资金进行委托理财的进展公告
Regulatory Filings Classification · 95% confidence The document is a progress announcement regarding the company's use of idle funds for entrusted financial management, detailing recent transactions, risk analysis, and control measures. It is a specific update on financial activities rather than a full financial report or earnings release. The document length is short (1810 characters) and it is an announcement of progress rather than a comprehensive report. It does not fit categories like Annual Report, Interim Report, or Earnings Release. It is best classified as a Regulatory Filing (RNS) because it is a regulatory disclosure about financial management activities that does not fit other specific categories.
2026-05-07 Chinese
关于召开2025年度股东会的通知
AGM Information Classification · 95% confidence The document is a detailed notice about the convening of the 2025 Annual General Meeting (AGM) of Beijing Leadman Biochemical Co., Ltd. It includes information about the meeting date, voting procedures, proposals to be voted on (including the 2025 annual report and financial statements), registration details, and attachments such as proxy forms and voting instructions. The document does not contain the actual annual report or financial statements but rather serves as an official notification to shareholders about the AGM and the matters to be discussed and voted upon. The document length is 4349 characters, which is relatively short and consistent with a meeting notice rather than a full report. Therefore, it fits the definition of AGM Information (AGM-R) rather than the Annual Report (10-K) or other categories.
