Filing Released Lang Actions
关于独立董事辞任暨补选独立董事及专门委员会委员的公告
Board/Management Information Classification · 1% confidence The document is an official announcement by the company regarding the resignation of an independent director and the nomination/election of a replacement and committee assignments. It details changes in board membership and committee composition rather than financial results or regulatory filings. This corresponds to the Board/Management Information category.
2026-04-22 Chinese
第四届董事会第七次会议决议公告
Regulatory Filings Classification · 1% confidence The document is a Chinese public company’s board of directors’ resolution announcement (“第四届董事会第七次会议决议公告”), listing the convening details and the votes on a wide range of proposals (annual report, work reports, profit distribution plan, budget, governance changes, appointments, etc.). It is not the underlying reports themselves (which are separately posted) nor a simple announcement of a report publication. While it includes one board change, its primary purpose is to communicate board meeting resolutions. Hence it is best classified as a general regulatory filing (RNS).

国投证券股份有限公司关于中山联合光电科技股份有限公司2025年度募集资金存放与使用情况的专项核查意见
Regulatory Filings Classification · 1% confidence The document is a detailed sponsor’s special verification opinion (“专项核查意见”) on the deposit and use of the company’s 2025 raised funds, prepared in accordance with listing rules and including an accountant’s verification. It is not a full Annual or Interim Report, earnings release, dividend notice, or M&A announcement, but rather a regulatory compliance disclosure. It therefore falls under the general Regulatory Filings category.
2026-04-22 Chinese

Audit Report / Information Classification · 1% confidence The document is a standalone report evaluating the external auditor’s (立信会计师事务所) 2025 audit engagement and performance, including audit scope, independence, procedures, and the resulting unqualified opinion.
