天衡会计师事务所（特殊普通合伙）关于苏州和林微纳科技股份有限公司2025年年度报告的信息披露监管问询函的回复
Regulatory Filings Classification · 85% confidence The document is a formal reply letter from the company’s external auditor (天衡会计师事务所) to the Shanghai Stock Exchange’s information‐disclosure regulatory inquiry regarding the company’s 2025 annual report. It is not the annual report itself (10-K) nor an earnings release, nor a proxy or dividend notice. It is an auditor’s compliance response to a regulator’s inquiry, which does not fit the standalone audit opinion template (AR) exactly but rather is a regulatory filing. Therefore it falls under the general “Regulatory Filings” category (RNS).

2025年度独立董事述职报告（江小三-已离任）
Board/Management Information Classification · 95% confidence The document is titled as an "Independent Director's Annual Report" for the year 2025 by an independent director of Suzhou Helin Micro-Nano Technology Co., Ltd. It details the director's background, attendance at board and committee meetings, communication with auditors, shareholders, and management, and evaluation of governance and internal controls during the reporting period. The content focuses on the independent director's duties, oversight, and governance activities rather than financial results or audit opinions alone. The document length is 4202 characters, which is relatively short but contains substantive content about board and management oversight rather than just an announcement or certification. This type of report is typically classified under Board/Management Information (MANG) as it relates to board member activities and governance reporting rather than a full annual report, audit report, or regulatory filing. Therefore, the most appropriate classification is MANG with high confidence.

2025年内部控制评价报告
Audit Report / Information Classification · 95% confidence The document is titled as an "Internal Control Evaluation Report" for the year 2025 by Suzhou Helin Micro-Nano Technology Co., Ltd. It discusses the evaluation of the company's internal control effectiveness as of December 31, 2025, including financial and non-financial internal control defects, audit opinions, scope of evaluation, standards for defect recognition, and rectification status. The content is detailed and specific to internal control evaluation rather than a full annual report or audit report. It is not a brief announcement or a certification letter but a substantive report on internal control evaluation. This type of document aligns with an Audit Report / Information (AR) category, which includes standalone audit reports and internal control evaluation results, excluding full annual reports. The document length (3897 characters) is relatively short but contains detailed internal control evaluation content, not just an announcement or certification. Therefore, the best classification is AR with high confidence. FY 2025

It also includes changes in company secretary and authorized representatives, which are management/board information. The document length is over 6,000 characters and contains substantive content but is primarily a board meeting resolution announcement rather than the full annual report or financial statements.
