Filing Released Lang Actions
潜能恒信关于会计师事务所2025年度履职情况评估及董事会审计委员会履行监督职责情况的报告
Governance Information Classification · 1% confidence The document is a report issued by the company’s Board Audit Committee evaluating the external auditor’s 2025 performance and describing the committee’s supervisory activities. It is not the audit opinion itself (so not an AR) nor a financial or management discussion of results (so not MDA). It primarily details governance oversight (audit committee procedures and compliance with governance rules), matching the Governance Information category (CGR).

对独立董事独立性评估的专项意见
Governance Information Classification · 1% confidence The document is a formal board-issued opinion assessing the independence of independent directors, referencing corporate governance rules and regulations. It is not announcing changes in board composition (MANG), nor is it a vote result (DVA), but rather relates to governance practices and compliance. Therefore, it falls under Governance Information.
2026-04-20 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 Zhongshenchonghuan Certified Public Accountants LLP for 潜能恒信能源技术股份有限公司, including the audit opinion, basis of opinion, key audit matters, auditor and management responsibilities, and the full set of audited financial statements (balance sheet, income statement, cash flow statement, shareholders’ equity changes, and notes). It is a standalone audit report rather than a full annual report, regulatory announcement, or any other category. Therefore, it should be classified as an Audit Report.
2026-04-20 Chinese
关于举行2025年度网上业绩说明会的通知
Regulatory Filings Classification · 0% confidence The document is a notice (“关于举行2025年度网上业绩说明会的通知”) inviting investors to an online performance briefing meeting regarding the 2025 annual results. It does not contain actual financial results, management changes, or the report itself, nor is it a transcript. There is no specific category for a conference call invitation, so this falls into the general regulatory announcement bucket: Regulatory Filings (RNS).
2026-04-20 Chinese
2025年度内部控制自我评价报告(1)
Audit Report / Information Classification · 1% confidence The document is a full-length 2025 internal control self-evaluation report prepared by the company’s board and management, detailing internal control scope, methodology, results, and remediation. It is not an announcement of publication but the substantive report itself. It is not a financial annual or interim report, earnings release, management change, or proxy statement. The closest match is the standalone audit/internal control report category (Audit Report / Information - AR).
2026-04-20 Chinese
关于购买董事、高级管理人员责任险的公告
Regulatory Filings Classification · 1% confidence The document is an official exchange announcement detailing a board resolution on purchasing directors and officers liability insurance and its submission for shareholder approval. It does not present financial results, governance code details, or proxy solicitation materials, nor does it fit into specialized categories like capital updates, M&A, or management changes. It is a general regulatory filing announcement by the company. Therefore, it falls under the fallback category: Regulatory Filings (RNS).
