宁波长阳科技股份有限公司第四届董事会第十次会议决议公告
Board/Management Information Classification · 95% confidence The document is a detailed announcement of resolutions passed at the 10th meeting of the 4th Board of Directors of Ningbo Changyang Technology Co., Ltd. It includes voting results on various agenda items such as approval of the 2025 annual report, management reports, audit reports, remuneration proposals, and other corporate governance matters. The document repeatedly references that the full reports and detailed documents are disclosed separately on the Shanghai Stock Exchange website, indicating this document itself is not the full reports but a summary of board decisions. The document is a formal announcement of board meeting resolutions, not the actual annual report or audit report. It also includes information about remuneration and other board-related approvals, but the primary nature is the board meeting resolutions announcement. Therefore, the document fits best into the category of Board/Management Information (MANG). The document length is 4422 characters, which is sufficient for a detailed board meeting resolution announcement but not a full annual report. Hence, the classification is MANG with high confidence.

立信会计师事务所（特殊普通合伙）关于宁波长阳科技股份有限公司2025年度营业收入扣除情况表的鉴证报告
Audit Report / Information Classification · 95% confidence The document is an audit-related report issued by a certified public accounting firm (BDO China Shu Lun Pan Certified Public Accountants LLP) for Ningbo Changyang Technology Co., Ltd. It specifically states it is a "鉴证报告" (assurance report) on the company's 2025 fiscal year "营业收入扣除情况表" (Operating Revenue Deduction Statement). The report includes the auditor's responsibilities, management's responsibilities, the scope of work, and the auditor's conclusion on the revenue deduction statement. It references the audited financial statements for the year ended December 31, 2025, but this document itself is not the full annual report or the audited financial statements. Instead, it is a standalone assurance report on a specific financial schedule related to revenue deductions, which is a type of audit report or audit-related information. The document is over 5,000 characters and contains substantive audit content and conclusions. Therefore, it fits best under the category of Audit Report / Information (AR).

宁波长阳科技股份有限公司2025年年度报告摘要
Annual Report Classification · 100% confidence The document is titled as the "2025年年度报告摘要" which translates to "2025 Annual Report Summary". It contains detailed financial data for the year 2025, including revenue, net profit, quarterly breakdowns, business descriptions, industry analysis, shareholder information, and risk disclosures. The length of the document (12,452 characters) and the depth of financial and operational information indicate it is a substantive report rather than a brief announcement or summary. The document explicitly states it is a summary of the annual report and references the full annual report for more details, which is typical for an Annual Report or 10-K equivalent. There is no indication that this is merely an announcement of report publication or a certification letter. Therefore, the document fits the definition of an Annual Report (10-K).

宁波长阳科技股份有限公司关于投资建设项目延期的公告
Capital/Financing Update Classification · 95% confidence The document is an official announcement from Ningbo Changyang Technology Co., Ltd. regarding the delay of an investment construction project. It details the project name, investment amount, reasons for the delay, and the impact on the company. The document is relatively short (1570 characters) and focuses on a specific project update rather than financial results or comprehensive reporting. It does not contain financial statements or detailed financial analysis. This type of announcement fits best under the category of Capital/Financing Update (CAP), as it relates to updates on company investment projects and capital expenditures.

宁波长阳科技股份有限公司关于续聘会计师事务所的公告
Regulatory Filings Classification · 95% confidence The document is an announcement regarding the company's decision to reappoint an accounting firm (Lixin CPA Firm) as the auditor for the fiscal year 2026. It details the auditor's background, personnel involved, audit fees, and the approval process by the board and shareholders. There are no actual financial statements or audit results included, nor is this a full audit report. The document is a formal announcement about the auditor appointment, not the audit report itself. The document length is 2431 characters, which is relatively short and consistent with an announcement rather than a full report. Therefore, this fits best under the category of Audit Report / Information (AR) as it relates to audit information but is not a full annual report or audit report containing financial data. However, since it is about the appointment of the auditor and not the audit report itself, it is more appropriate to classify it as Regulatory Filings (RNS) because it is a regulatory announcement about auditor appointment and not the audit report or audit results.
