Filing Released Lang Actions
2025年度非经营性资金占用及其他关联资金往来情况汇总表
Regulatory Filings Classification · 0% confidence The document is a standalone tabular summary of 2025 non-operating fund occupation and related‐party transactions (“非经营性资金占用及其他关联资金往来情况汇总表”). It is not an Annual Report (10-K) or Interim Report, nor is it a simple announcement (no text indicating “report is attached” or publication notice), earnings release, proxy/solicitation, management commentary, or any other specific category. As there is no dedicated category for related‐party schedules, it falls under the fallback “Regulatory Filings” (RNS).

关于作废部分已授予但尚未归属的第二类限制性股票的公告
Regulatory Filings Classification · 1% confidence The document is a corporate announcement detailing the cancellation of unvested restricted shares under the 2023 equity incentive plan due to unmet performance conditions. It is not a full annual report, earnings release, board appointment, dividend notice, or similar, nor is it simply announcing the publication of a report. It deals with a corporate action related to share incentives, a category not explicitly listed; thus it defaults to General Regulatory Filings (RNS).

2025年度内部控制自我评价报告
Audit Report / Information Classification · 1% confidence The document is a standalone Internal Control Self-Evaluation Report (“内部控制自我评价报告”) prepared by the company’s board and audit committee, detailing internal control design, testing, and conclusions. It is not an annual/quarterly financial report, earnings release, or simple announcement but a formal internal audit/control assessment. Therefore, it best fits the Audit Report / Information category (AR).

控股股东及其他关联方资金占用情况的专项说明（截止2025年12月31日）
Audit Report / Information Classification · 1% confidence The document is a special explanatory report (“专项说明”) issued by the external auditor (Beijing Dehao International CPA LLP) on the company’s related‐party/non-operational fund use, prepared under CSRC and exchange guidelines. It is not the full audited financial statements (annual or interim report) nor merely an announcement; rather it is a standalone audit‐related report providing additional assurance on specific related‐party transactions. This fits the definition of a standalone Audit Report / Information.
