2025年年度股东会会议资料
AGM Information Classification · 91% confidence The document is titled “2025年年度股东会会议资料” and comprises the meeting materials for the 2025 Annual General Meeting (AGM), including meeting notices, agenda items, proposals (e.g., approval of the annual report, profit distribution, board reports, appointment of auditors), and related attachments. It does not contain full financial statements as a standalone annual report but is clearly the presentation and materials distributed for an AGM. Therefore, it fits the AGM Information category.

关于使用募集资金置换募投项目预先投入的自筹资金及已支付发行费用的公告
Capital/Financing Update Classification · 95% confidence The document is an official announcement from Shenzhen Hengyunchang Vacuum Technology Co., Ltd. regarding the use of raised funds to replace self-raised funds previously invested in projects and paid issuance expenses. It details the amounts, approvals by the board and audit committee, and includes opinions from the accounting firm and sponsor. The content focuses on the company's capital management and fundraising activities, specifically the replacement of pre-invested funds with raised capital. It is not a full financial report, audit report, or earnings release, but rather an update on capital usage related to fundraising. The document length is 3774 characters, which is relatively short but contains substantive information about capital usage rather than just announcing a report. Therefore, it fits best under Capital/Financing Update (CAP).

深圳市恒运昌真空技术股份有限公司投资者关系管理制度
Governance Information Classification · 95% confidence The document is titled '投资者关系管理制度' which translates to 'Investor Relations Management System'. It outlines the company's policies and procedures for managing communication and relationships with investors, including principles, responsibilities, communication methods, and compliance with relevant laws and regulations. It does not contain financial statements, earnings data, audit results, or any specific report disclosures. Instead, it is a governance document detailing how the company manages investor relations and information disclosure. This fits the definition of Governance Information (CGR), which covers reports detailing the company's internal rules, board structure, and governance practices. The document length is 5520 characters, sufficient for a detailed governance policy. Therefore, the correct classification is CGR with high confidence.

深圳市恒运昌真空技术股份有限公司内幕信息知情人登记管理制度
Regulatory Filings Classification · 95% confidence The document is a detailed internal policy and procedural manual titled "内幕信息知情人登记管理制度" (Insider Information Insider Registration Management System) issued by Shenzhen Hengyun Vacuum Technology Co., Ltd. It outlines the definitions, scope, management, confidentiality, and responsibilities related to insider information and insider personnel registration. It includes references to Chinese securities laws, regulatory bodies (China Securities Regulatory Commission, Shanghai Stock Exchange), and company governance rules. The document contains procedural guidelines, forms for insider information registration, confidentiality agreements, and commitment letters. It is not a financial report, earnings release, or announcement of voting results. It is a regulatory compliance and governance document focused on insider information management and confidentiality obligations. It does not contain financial statements or audit opinions, nor is it a call transcript or capital update. It is a governance-related internal control document. Therefore, the most appropriate classification is Regulatory Filings (RNS), as it is a regulatory compliance document that does not fit into more specific categories like Annual Report, Audit Report, or Governance Information (CGR) which typically cover board structure and governance practices rather than insider information management policies.

关于召开2025年年度股东会的通知
AGM Information Classification · 95% confidence The document is a detailed notice about the convening of the 2025 Annual General Meeting (AGM) of Shenzhen Hengyunchang Vacuum Technology Co., Ltd. It includes information about the meeting date, voting methods, agenda items to be discussed and voted on, shareholder registration details, and proxy authorization forms. The document does not contain the actual annual report or financial statements but rather the notification and materials related to the AGM itself. The presence of agenda items such as the 2025 annual report and board work report indicates it is an AGM notice. The document length is about 5451 characters, which is consistent with a detailed AGM notice rather than a full annual report. Therefore, the appropriate classification is AGM Information (AGM-R).
