宁波长阳科技股份有限公司第四届监事会第五次会议决议公告
Declaration of Voting Results & Voting Rights Announcements Classification · 95% confidence The document is a resolution announcement from the Supervisory Board of Ningbo Changyang Technology Co., Ltd. regarding the fifth meeting of the fourth Supervisory Board. It includes approvals of the 2025 semi-annual report and related matters, but the actual semi-annual report is disclosed separately on the Shanghai Stock Exchange website. The document is short (1968 characters) and mainly announces meeting resolutions and references other detailed reports published elsewhere. According to the 'Menu vs Meal' rule, this is an announcement of meeting resolutions and voting results rather than the full interim report itself. Therefore, it fits best under Declaration of Voting Results & Voting Rights Announcements (DVA).

宁波长阳科技股份有限公司关于开展外汇套期保值业务的公告
Regulatory Filings Classification · 95% confidence The document is an announcement from Ningbo Changyang Technology Co., Ltd. regarding the commencement of foreign exchange hedging business. It details the business scope, risk analysis, risk control measures, and approvals by the board and supervisory committee. The document is a formal announcement about a specific business activity and risk management, not a financial report, earnings release, or regulatory certification. It does not contain financial statements or detailed financial data. It is also not a report publication announcement or a certification letter. The content fits best under a general regulatory announcement category about business operations and risk management, which aligns with Regulatory Filings (RNS).

宁波长阳科技股份有限公司董事、高管减持股份结果公告
Director's Dealing Classification · 100% confidence The document is titled as an announcement regarding the results of shareholding reduction by directors and senior management of Ningbo Changyang Technology Co., Ltd. It details the shareholding before and after the reduction, the reduction plan, and the completion status. The content focuses on insider share transactions by company directors and executives, including specific share quantities, dates, and prices. There is no financial performance data, no mention of financial reports, or other types of filings. This matches the definition of a Director's Dealing report, which covers personal share transactions by company directors and executives (insider trades). The document length is about 3005 characters, which is sufficient for a detailed announcement but not a full financial report. Therefore, the correct classification is Director's Dealing (DIRS).

华安证券股份有限公司关于宁波长阳科技股份有限公司2024年年度报告的信息披露监管问询函回复的核查意见
Annual Report Classification · 95% confidence The document is a detailed response to a regulatory inquiry from the Shanghai Stock Exchange regarding the 2024 annual report of Ningbo Changyang Technology Co., Ltd. It includes extensive financial data, analysis of subsidiary performance, investment project progress, industry comparisons, and explanations of losses and economic outlook. The content is comprehensive, covering the full fiscal year 2024, with detailed financial statements and management explanations. This matches the characteristics of an Annual Report (10-K) rather than a brief announcement or a certification. The document length (15,000 characters) and depth of financial and operational detail confirm it is the report itself, not just an announcement or a regulatory filing. Therefore, the correct classification is Annual Report (10-K).

宁波长阳科技股份有限公司关于2024年年度报告信息披露监管问询函的回复公告
Annual Report Classification · 95% confidence The document is a detailed reply to a regulatory inquiry letter regarding the company's 2024 Annual Report. It contains extensive financial data, analysis of subsidiary performance, investment projects, industry comparisons, and audit opinions. The document references the 2024 Annual Report and provides detailed explanations and data related to it, including financial figures, project progress, and management responses. The length is substantial (15,000 characters), and it is not merely an announcement or a certification. Therefore, this document is the actual Annual Report or a detailed regulatory reply closely tied to the Annual Report content. Given the detailed financial and operational data, it fits best under the Annual Report (10-K) category rather than a simple Regulatory Filing or Report Publication Announcement.
