2025年度内部控制自我评价报告
Audit Report / Information Classification · 95% confidence The document is titled '2025年度内部控制自我评价报告' which translates to '2025 Internal Control Self-Evaluation Report'. It is a detailed report on the company's internal control system, its effectiveness, risk assessment, control activities, and evaluation procedures related to internal controls as of December 31, 2025. The document includes detailed descriptions of governance, risk management, control activities, and internal audit functions. It explicitly states the evaluation of internal control effectiveness related to financial reporting and non-financial reporting. The document is not an announcement of a report but the report itself, containing substantive content and analysis. This type of document aligns with an Audit Report / Information (AR) as it focuses on internal control evaluation and audit-related information rather than a full Annual Report (10-K) or other categories. Therefore, the appropriate classification is AR with high confidence. FY 2025

国联民生承销保荐有限公司关于威海市天罡仪表股份有限公司2025年度募集资金存放与使用情况的专项核查报告
Audit Report / Information Classification · 95% confidence The document is titled as a "专项核查报告" (special inspection report) regarding the 2025 annual status of fundraising funds storage and usage for Weihai Tiangang Instrument Co., Ltd. It is issued by the underwriting and sponsoring institution Guolian Minsheng Securities Co., Ltd. The content details the amount of funds raised, their storage, management, usage, and compliance with regulatory requirements. It includes detailed tables of funds usage, bank accounts, and investment products related to the raised funds. The document also contains audit opinions from an accounting firm and verification opinions from the sponsor institution. The document is focused specifically on the annual inspection and verification of the use and storage of raised funds, which aligns with the definition of an Audit Report / Information (AR) as it is a standalone audit-type report on a specific regulatory compliance matter, not a full annual report or earnings release. The length (6081 characters) and detailed financial data support it being a substantive report rather than a brief announcement. Therefore, the appropriate classification is AR (Audit Report / Information). FY 2025

It includes tables showing shareholding changes and confirms compliance with regulatory requirements. There is no financial statement, earnings data, or management discussion. The document is a regulatory announcement about share status changes rather than a financial report or meeting material. Therefore, it fits best under the category of Share Issue/Capital Change (SHA), which covers announcements regarding changes in share capital or share status such as lifting trading restrictions on shares.

2025年年度业绩快报公告
Earnings Release Classification · 95% confidence The document is titled as a '2025 Annual Performance Express Report' and contains preliminary financial data for the year 2025, including revenue, profit, net assets, and earnings per share. It explicitly states that the data is preliminary and unaudited, with final audited figures to be disclosed in the 2025 Annual Report. The document is relatively short (1750 characters) and serves as a performance preview or earnings alert rather than a full comprehensive annual report. It does not contain full audited financial statements or detailed management discussion and analysis. Therefore, it fits the definition of an Earnings Release (ER), which is an initial announcement of periodic financial results with key highlights only. FY 2025
