海通证券关于合肥新汇成微电子股份有限公司2024年度募集资金存放与实际使用情况的核查意见
Audit Report / Information Classification · 95% confidence The document is a detailed report on the 2024 annual verification of the storage and actual use of funds raised by Hefei Xinhui Cheng Microelectronics Co., Ltd. It includes extensive financial data on the amount raised, usage, bank accounts, investment projects, and compliance with regulatory requirements. It references specific regulatory guidelines and includes auditor verification opinions. The document is lengthy (over 11,000 characters) and contains substantive financial data and analysis related to the use of raised funds. This matches the characteristics of an Audit Report / Information (AR), which covers audit reports, applied accounting principles, and verification of fund usage, but is not a full Annual Report. It is not an announcement or a brief summary, nor is it a certification letter or a proxy statement. Therefore, the best classification is AR (Audit Report / Information).

2024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 "2024年度募集资金存放与实际使用情况专项报告" which translates to "2024 Annual Special Report on the Deposit and Actual Use of Raised Funds." It details the amount of funds raised through convertible bonds, their deposit, management, and actual usage during the 2024 fiscal year. It includes detailed financial tables, descriptions of fund management, usage, and compliance with regulatory requirements. The document also contains auditor and sponsor institution opinions on the fund usage. This is a specialized report focused on the management and use of capital raised by the company, not a general annual report or earnings release. It is not a brief announcement but a substantive report with financial data and analysis. Therefore, it fits best under the category of Capital/Financing Update (CAP), which covers updates on company fundraising and capital structure changes.

2024年度内部控制评价报告
Audit Report / Information Classification · 95% confidence The document is titled '2024年度内部控制评价报告' which translates to '2024 Internal Control Evaluation Report'. It discusses the company's internal control evaluation as of December 31, 2024, including the effectiveness of financial reporting internal controls, identification of any significant deficiencies, and corrective actions. The content is focused on internal control evaluation rather than full financial statements or annual performance. The document length is 4405 characters, which is relatively short but contains substantive evaluation content rather than just an announcement. This type of report is typically classified as an Audit Report / Information (AR) because it deals with internal control evaluation and audit opinions on internal controls, not a full annual report or interim financial report. It is not a Regulatory Filing (RNS) because it contains detailed evaluation content, not just a certification or announcement. Therefore, the best fit is AR (Audit Report / Information).

合肥新汇成微电子股份有限公司2024年年度报告
Annual Report Classification · 100% confidence The document is titled "合肥新汇成微电子股份有限公司 2024 年年度报告" which translates to "Union Semiconductor (Hefei) Co., Ltd. 2024 Annual Report." It contains detailed sections including company overview, financial data, management discussion and analysis, corporate governance, environmental and social responsibility, and audited financial statements. The document length is substantial (15,000 characters) and includes comprehensive financial and operational information for the fiscal year 2024. It also mentions the audit report with an unqualified opinion by the accounting firm. The presence of detailed financial data, management analysis, and audit information confirms this is the full official yearly report covering company activity and full financial performance for the year 2024. Therefore, the document fits the definition of an Annual Report (10-K).
2025-03-27 Chinese
第二届监事会第八次会议决议公告
Board/Management Information Classification · 95% confidence The document is a detailed announcement of resolutions passed at the 8th meeting of the 2nd Supervisory Board of Hefei New Huicheng Microelectronics Co., Ltd. It includes approvals of various reports and proposals related to the 2024 annual report, financial statements, budget, profit distribution, internal control evaluation, audit firm performance, and other governance matters. The document repeatedly states that these resolutions will be submitted to the 2024 annual shareholders' meeting for approval. It also references that the full reports are disclosed separately on the Shanghai Stock Exchange website. The document itself is a formal announcement of supervisory board meeting decisions rather than the full annual report or financial statements. Given the nature of the content—meeting resolutions and approvals related to the annual report and other governance documents—this fits best under Board/Management Information (MANG), which covers announcements of changes or decisions by company boards or supervisory bodies. It is not the annual report itself (10-K), nor a simple announcement of report publication (RPA), but a detailed supervisory board meeting resolution announcement. The document length (4984 characters) supports it being a full announcement rather than a brief notice. Therefore, the classification is MANG with high confidence.

关于使用部分暂时闲置自有资金进行现金管理的公告
Capital/Financing Update Classification · 95% confidence The document is an announcement by Hefei Xinhui Microelectronics Co., Ltd. regarding the use of temporarily idle own funds for cash management. It details the purpose, amount, types of financial products involved, risk control measures, and the approval process by the board and supervisory committee. The document is a formal disclosure about financing activities related to cash management, not a full financial report or earnings release. It does not contain financial statements or detailed financial results, nor is it a report publication announcement. The content fits best under Capital/Financing Update (CAP) as it concerns the company's financing activities and capital management strategies.
