国泰海通证券股份有限公司关于东莞铭普光磁股份有限公司2025年度募集资金存放与使用情况的专项核查意见
Regulatory Filings Classification · 82% confidence The document is a sponsor’s special verification opinion (“专项核查意见”) on the 2025 use and storage of IPO proceeds by Dongguan Mingpu Optical Magnetic Co., Ltd. It is a regulatory compliance report under China Securities Regulatory and Shenzhen Stock Exchange rules, prepared by the sponsor (Guotai Haitong Securities). It is not an AGM presentation, earnings release, management discussion, or dividend notice, nor is it a formal audit of financial statements by an accounting firm. There is no dedicated category for a sponsor’s proceeds‐usage verification; therefore, it falls into the fallback category for miscellaneous regulatory filings. Thus, the correct classification is Regulatory Filings (RNS).

国泰海通证券股份有限公司关于东莞铭普光磁股份有限公司2025年度内部控制自我评价报告的核查意见
Audit Report / Information Classification · 85% confidence The document is a formal review opinion by the sponsor (保荐人) on the company’s internal control self-evaluation report. It does not present full financial statements like an annual or interim report, nor is it an earnings release or management presentation. Instead, it is a standalone audit-style verification of internal control, fitting the definition of an Audit Report/Information (AR).

对外担保管理制度
Governance Information Classification · 90% confidence The document is an internal company policy (“对外担保管理制度”) detailing procedures, approvals, and disclosures for external guarantees. It is not a financial report, earnings release, or announcement, but rather a governance manual outlining the company’s internal rules and processes. Therefore, it best fits the Governance Information category.

国泰海通证券股份有限公司关于东莞铭普光磁股份有限公司2025年度日常关联交易执行情况的核查意见
Regulatory Filings Classification · 78% confidence The document is a detailed sponsor’s check opinion (“核查意见”) on the company’s 2025 related‐party transactions, prepared under applicable exchange rules by the sponsor (国泰海通证券). It is not an earnings release, annual or interim report, audit report, ESG report, proxy statement, or dividend notice. It does not announce publication of another report but contains the substantive findings itself. No specific category for a sponsor’s related‐party transaction review exists, so it falls under the fallback: a miscellaneous regulatory filing (RNS).
