2025年年度股东会会议资料
AGM Information Classification · 95% confidence The document is titled “2025年年度股东会会议资料” and contains detailed meeting instructions, agenda items, proposals (e.g., board work report, profit distribution, director elections), and attachments for the 2025 Annual General Meeting. It is a set of materials to be presented at the AGM rather than the report itself or an announcement. Therefore, it should be classified as AGM Information.

持股5%以上股东减持股份计划公告
Major Shareholding Notification Classification · 75% confidence The document is an official announcement by a 5%+ shareholder (Wu Kaiting) of Beijing JianKai Technology Co., Ltd. detailing a plan to reduce his holdings via on‐market and block trades over a defined future period. It is not an earnings release, dividend notice, or company‐led share repurchase; nor is it a director/executive insider deal (the shareholder is not a director). This type of disclosure falls under “Major Shareholding Notification” where a significant shareholder informs the market of planned changes in their stake.

2025年度内部控制评价报告
Audit Report / Information Classification · 95% confidence The document is titled '2025年度内部控制评价报告' which translates to '2025 Internal Control Evaluation Report'. It discusses the evaluation of the company's internal control effectiveness as of December 31, 2025. The content includes detailed descriptions of internal control scope, evaluation criteria, defect classifications, and conclusions about the effectiveness of financial and non-financial internal controls. It is a standalone report focused on internal control evaluation rather than a full annual report or audit report. The document length is 4201 characters, which is relatively short but contains substantive evaluation content rather than just an announcement or certification. This type of document aligns with an Audit Report / Information (AR) category, as it relates to internal control evaluation and audit committee oversight, but is not a full annual report (10-K) or a certification letter (RNS).

关于会计师事务所2025年度履职情况评估报告
Audit Report / Information Classification · 95% confidence The document is titled as an evaluation report on the performance of the accounting firm for the year 2025. It details the background, qualifications, quality management, and overall assessment of the audit firm (PwC Zhongtian) engaged for the 2025 annual audit. It discusses the audit firm's procedures, quality control, and compliance with regulations, but does not contain actual financial statements or audit results. The document is a standalone audit-related report focusing on the audit firm's performance and quality management rather than the company's full annual report or audit report itself. It is not a full Annual Report (10-K) or an Interim Report (IR), nor is it a simple announcement or certification. This fits the definition of an Audit Report / Information (AR) which includes standalone audit reports and applied accounting principles or internal audit evaluations. The document length is 2813 characters, which is relatively short but contains substantive content about audit quality and performance, not just an announcement. Therefore, the best classification is AR with high confidence.

2025年年度利润分配方案公告
Notice of Dividend Amount Classification · 100% confidence The document is a profit distribution plan announcement for the fiscal year 2025 by Beijing Jiankai Technology Co., Ltd. It details the dividend per share, total cash dividend amount, and related financial figures. The document is relatively short (2569 characters) and focuses on the dividend distribution scheme rather than providing a full annual report or comprehensive financial statements. It also mentions that the plan will be submitted to the 2025 annual shareholders meeting for approval. This type of document is a Notice of Dividend Amount, as it announces the dividend amount, payment basis, and related shareholder information. It is not a full Annual Report (10-K) or Earnings Release (ER), nor is it a report publication announcement. Therefore, the correct classification is Notice of Dividend Amount (DIV).
2026-04-28 Chinese
关于董事会审计委员会对会计师事务所2025年度履行监督职责情况的报告
Audit Report / Information Classification · 95% confidence The document is a report from the company's Board Audit Committee regarding the supervision of the accounting firm PwC Zhongtian for the 2025 fiscal year audit. It details the appointment, qualifications, and oversight activities related to the external auditor's work on the company's 2025 financial statements and internal control audit. The document does not contain the actual audited financial statements or detailed financial data but rather focuses on the audit committee's supervisory role and evaluation of the auditor's performance. This fits the definition of an Audit Report / Information (AR), which includes standalone audit reports and results of internal or regulatory oversight related to audits, excluding full annual reports. The document length is under 5,000 characters, but it is a substantive report on audit supervision, not merely an announcement or certification. Therefore, the appropriate classification is AR with high confidence.
