Filing Released Lang Actions
中信建投证券股份有限公司关于清研环境科技股份有限公司首次公开发行股票并在创业板上市之持续督导保荐工作总结报告书
Regulatory Filings Classification · 85% confidence The document is a sponsor’s continuous supervision summary report (“持续督导保荐工作总结报告书”) prepared by the IPO sponsor after the listing. It is not an earnings release, financial statement, proxy or AGM material, nor is it a US Form, call transcript, or capital issuance announcement. It is a required regulatory compliance document detailing the sponsor’s ongoing review of corporate governance and fund usage. It does not simply announce that another report is available (so it is not RPA), but is itself the regulatory report, fitting the fallback “Regulatory Filings” category.

关于公司股票撤销退市风险警示暨停复牌的公告
Regulatory Filings Classification · 85% confidence The document is a formal regulatory announcement about the company’s stock trading status—specifically, the suspension and resumption of trading and the removal of a delisting risk warning. It does not present financial statements or governance reports, nor is it a capital/financing, M&A, or dividend notice. There is no indication of a vote, share issue, or executive dealings. It is not a delisting notice in the sense of removal from the exchange but rather a risk-warning removal and trading status update. Thus, it falls under the general fallback category for miscellaneous regulatory announcements.

Although it includes legal commentary, its primary content and regulatory function is to declare and confirm the voting procedures and results of the AGM. This matches our category “Declaration of Voting Results & Voting Rights Announcements (DVA).”

中信建投证券股份有限公司关于清研环境科技股份有限公司2025年度跟踪报告
Regulatory Filings Classification · 95% confidence The document is titled as a '2025年度跟踪报告' (2025 Annual Tracking Report) by a sponsoring institution (中信建投证券股份有限公司) regarding 清研环境科技股份有限公司. It details the sponsor's review and supervision activities, including information disclosure, internal controls, fundraising supervision, governance, and training. It also reports on regulatory actions and compliance measures. The content is focused on the sponsor's monitoring and oversight work rather than the company's own financial statements or management discussion. The document length is 2109 characters, which is relatively short and more consistent with a monitoring or tracking report rather than a full annual or interim financial report. It does not contain financial statements or detailed financial analysis. This type of document is best classified as a Regulatory Filing (RNS) because it is a regulatory compliance and monitoring report by the sponsor, not a full financial report or announcement of voting results, management changes, or capital updates.

关于举办2025年度网上业绩说明会的公告
Investor Presentation Classification · 95% confidence The document is an announcement about the scheduling of an online earnings presentation (业绩说明会) for the 2025 annual report, including details on how investors can participate and submit questions. It references the 2025 annual report already disclosed on April 21, 2026, but does not contain the report itself or detailed financial data. The document is short (646 characters) and serves as a notice for an upcoming event related to the annual report, not the report itself. Therefore, it fits the category of Investor Presentation (IP) as it focuses on a detailed presentation for investors about financials and company strategy.
