Filing Released Lang Actions
关于使用闲置自有资金进行现金管理的公告
Regulatory Filings Classification · 1% confidence The document is a corporate announcement by a listed Chinese company (Shenzhen Stock Exchange) disclosing the board’s resolution to use idle self-owned funds for short-term cash management. It does not report financial results (annual, interim or earnings), nor does it concern share issues, dividends, M&A, insider deals, or governance policies. It is a regulatory disclosure required under listing rules and does not fit any more specific category, so it defaults to a general Regulatory Filing (RNS).
2026-04-14 Chinese
关于举行2025年度网上业绩说明会的公告
Investor Presentation Classification · 1% confidence The document is an announcement by 中密控股股份有限公司 about holding its 2025 online performance briefing (业绩说明会), i.e., an investor presentation of annual results. It is not the full annual report, earnings release, or transcript itself but it sets up an investor-focused presentation event. Therefore it best matches the Investor Presentation category (IP).
2026-04-14 Chinese
公司章程(2026年4月）
Governance Information Classification · 1% confidence The document is the full text of the company's Articles of Association (章程), detailing its governance framework: internal rules, shareholder rights, board structure, committees, management roles, audit provisions, amendment processes, etc. It is not an earnings report, notice, or announcement—it is the core governance charter. This aligns exactly with the “Governance Information” category.
2026-04-14 Chinese
董事、高级管理人员薪酬管理制度（2026年4月）
Remuneration Information Classification · 1% confidence The document is a formal internal policy (“薪酬管理制度”) outlining the compensation management system for the company’s board of directors and senior management. It specifies principles, structures, approval processes, performance criteria, and recovery mechanisms, directly detailing remuneration arrangements for top executives. This fits the “Remuneration Information (DEF 14A)” category: reports detailing executive and director compensation schemes.
2026-04-14 Chinese
关于拟回购注销2024年限制性股票激励计划部分限制性股票的公告
Transaction in Own Shares Classification · 1% confidence The document is a corporate announcement detailing the company’s planned repurchase and cancellation of its own restricted stock under a 2024 incentive plan, including number of shares, repurchase price, impact on registered capital, board approvals, and legal opinion. This is clearly a share buyback/cancellation transaction by the company itself. It does not announce a dividend, share issuance, or broader financial report, but specifically outlines a repurchase of own shares. Therefore it falls under Transaction in Own Shares (POS).
2026-04-14 Chinese
2025年年度审计报告
Audit Report / Information Classification · 1% confidence The document is titled “审计报告” (Audit Report) issued by ShineWing certified public accountants and contains the auditor’s opinion, basis of audit, key audit matters, responsibilities, and detailed financial statements. It is a standalone audit report separate from a full annual report. Therefore, it fits the “Audit Report / Information” category.
