公司章程（2026年3月）
Governance Information Classification · 100% confidence The document is titled as the Articles of Association (章程) of 合肥新汇成微电子股份有限公司 dated March 2026. It contains detailed company governance rules, shareholder rights, board structure, share issuance and transfer rules, meeting procedures, and other corporate governance matters. It references relevant laws and regulations such as the Company Law, Securities Law, and listing rules of the Shanghai Stock Exchange. The content is a comprehensive governance document that sets out the internal rules and structure of the company rather than a financial report, announcement, or other filing types. Therefore, this document fits the category of Governance Information (CGR). The document length is substantial and contains the full text of the governance charter, not just an announcement or summary, so it is not an RPA or RNS. Hence, the classification is CGR with high confidence.

2025年度独立董事述职报告（罗昆）
Board/Management Information Classification · 95% confidence The document is titled as an "Independent Director's Work Report for 2025" from Hefei Xinhui Microelectronics Co., Ltd. It details the independent director's duties, attendance at meetings, communication with auditors, internal audit, and shareholders, as well as evaluations of governance and compliance with laws and regulations. It includes no financial statements or substantive financial data but focuses on the director's role, governance, and oversight activities during the year. This type of document is a report on board/management activities, specifically the independent director's annual work report, which fits best under the category of Board/Management Information (MANG). The document length is about 4500 characters, which is sufficient for a detailed report but does not contain financial results or audit opinions that would classify it as Annual Report (10-K), Audit Report (AR), or Interim Report (IR).

2025年度募集资金存放与实际使用情况专项报告
Capital/Financing Update Classification · 95% confidence The document is titled as a "2025年度募集资金存放与实际使用情况专项报告" which translates to "2025 Annual Special Report on the Deposit and Actual Use of Raised Funds." It details the amount of funds raised through convertible bonds, the management and storage of these funds, their actual usage, and includes tables with financial figures related to the raised funds. It also references compliance with regulatory rules from the China Securities Regulatory Commission and the Shanghai Stock Exchange. The document includes an auditor's verification report and a sponsor's special inspection report on the use of the raised funds. The content is focused on the specific use and management of capital raised by the company, not a general annual report or earnings release. This matches the description of a Capital/Financing Update (CAP), which covers updates on company fundraising and capital structure changes. The document is substantive and over 7,000 characters, so it is not merely an announcement of a report but the report itself. Therefore, the correct classification is CAP with high confidence.
