苏州纳微科技股份有限公司2025年度会计师事务所履职情况评估报告
Audit Report / Information Classification · 95% confidence The document is titled as an evaluation report on the performance of the accounting firm (auditor) for the fiscal year 2025. It discusses the auditor's qualifications, resources, audit plan, quality management, and compliance with professional standards. It does not contain actual financial statements or detailed financial results of the company itself, but rather an assessment of the auditor's work and independence. The document length is 3408 characters, which is relatively short and focused on audit firm evaluation rather than a full audit report or annual report. This fits the definition of an Audit Report / Information (AR) filing, which includes standalone audit reports and evaluations related to audit work, excluding full annual reports. Therefore, the correct classification is AR with high confidence. FY 2025

苏州纳微科技股份有限公司关于作废处理2024年限制性股票激励计划部分限制性股票的公告
Share Issue/Capital Change Classification · 95% confidence The document is an official announcement from Suzhou Nanwei Technology Co., Ltd. regarding the cancellation of part of the 2024 restricted stock incentive plan. It details board meetings, supervisory board meetings, legal opinions, and the reasons for the cancellation of certain restricted stocks due to unmet performance targets. The document is a formal announcement about a corporate action related to stock incentives, specifically the cancellation of restricted stock awards. It does not contain financial statements or detailed financial performance data, nor is it a report or presentation. It is not a regulatory certification or a voting result announcement. The document fits best into a category related to capital changes or share issues, specifically the cancellation of restricted stock awards, which is a capital change event. Therefore, the most appropriate classification is Share Issue/Capital Change (SHA). The document length is 3005 characters, which is relatively short but contains substantive information about the stock incentive plan changes, not just a report publication announcement or a regulatory filing. Confidence is high due to the clear focus on stock incentive plan changes and cancellation of shares.

苏州纳微科技股份有限公司2025年度独立董事年度述职报告（旷攀峰）
Regulatory Filings Classification · 85% confidence The document is a 2025年度独立董事述职报告 (“Independent Director’s Annual Work Report”), containing the full text of the independent director’s compliance and activity summary rather than announcing a board change, proxy materials, financial results, or statutory financial statements. It does not fit the specific categories for annual reports, earnings releases, MD&A, board changes, or proxy statements. It is a regulatory compliance disclosure by an officer, so it falls into the fallback “Regulatory Filings (RNS)” category.

北京市中伦（上海）律师事务所关于苏州纳微科技股份有限公司2024年限制性股票激励计划部分限制性股票作废事项的法律意见书
Regulatory Filings Classification · 30% confidence The document is a legal opinion letter issued by a law firm regarding the partial cancellation of restricted stock under the company’s 2024 equity incentive plan. It contains legal analysis and statements of compliance with relevant laws and regulations. It is not an annual or interim report, earnings release, proxy statement, or other structured financial disclosure—it is a compliance/legal advisory document filed alongside the incentive plan materials. Under the taxonomy, this type of miscellaneous regulatory compliance document falls under the fallback category “Regulatory Filings (RNS).”

容诚会计师事务所（特殊普通合伙）关于苏州纳微科技股份有限公司2025年度募集资金存放与实际使用情况的鉴证报告
Audit Report / Information Classification · 95% confidence The document is a specialized assurance (audit) report prepared by a registered accounting firm on the company’s use, management, and storage of IPO proceeds for the 2025 fiscal year. It provides an independent opinion rather than full annual financial statements or an earnings summary. This falls under standalone audit reports or specialized audit information, matching the Audit Report / Information (AR) category. FY 2025

苏州纳微科技股份有限公司第三届董事会第十四次会议决议公告
Board/Management Information Classification · 95% confidence The document is a detailed announcement of the resolutions passed at the 14th meeting of the 3rd Board of Directors of Suzhou Nano Micro Technology Co., Ltd. It includes approvals of the 2025 Annual Report and its summary, financial statements, budget, various reports, profit distribution plan, internal control evaluation, and multiple proposals related to the company's 2026 targeted issuance of A-shares. The document also references that the full 2025 Annual Report and other detailed reports are published separately on the Shanghai Stock Exchange website. The document is a formal board meeting resolution announcement, not the actual annual report or financial statements themselves. It contains extensive board decisions and approvals, including capital raising plans and remuneration system revisions, but it is primarily a board meeting resolutions announcement. This fits the category of Board/Management Information (MANG), which covers announcements of changes or decisions by the board. It is not a full Annual Report (10-K) or an Earnings Release (ER), nor is it a simple report publication announcement (RPA) because it contains substantive board resolutions. Therefore, the correct classification is MANG with high confidence.
