关于聘任高级管理人员的公告
Board/Management Information Classification · 95% confidence The document is an announcement regarding the appointment of senior management personnel at the company. It details the names, positions, and qualifications of the newly appointed executives. There is no financial data, no mention of financial results, no regulatory certifications, or report publications. The content focuses solely on management changes, which fits the category of Board/Management Information (MANG). The document length is short and it is not a report or a report announcement, so it is not an Annual Report or similar. Therefore, the correct classification is MANG with high confidence.

关于对2021年业绩预告关注函的阶段性回复公告
Annual Report Classification · 95% confidence The document is a detailed announcement from 启迪环境科技发展股份有限公司 regarding their 2021 annual performance forecast and responses to regulatory inquiries, including asset impairment, project exits, and related accounting treatments. It references the 2021 annual performance forecast, half-year reports, and ongoing audit work for the 2021 annual financial statements. The document includes extensive financial data, project details, impairment testing, and auditor's review procedures. It is not merely an announcement of a report but contains substantive financial and operational information related to the company's annual results and regulatory compliance. The document also discusses regulatory investigations and ongoing audit processes. Given the detailed financial disclosures, audit commentary, and focus on the full fiscal year 2021, this document fits the definition of an Annual Report (10-K) or equivalent comprehensive yearly report covering company activity and full financial performance. Although it is a reply to a regulatory letter, the length (15,000 characters) and content indicate it is a substantive report rather than a short announcement or certification. Therefore, the appropriate classification is Annual Report (10-K).

大信会计师事务所（特殊普通合伙）关于对启迪环境科技发展股份有限公司2021年年度业绩预告关注函的回复
Audit Report / Information Classification · 95% confidence The document is a detailed response to a regulatory inquiry from the Shenzhen Stock Exchange regarding the company's 2021 annual performance forecast and related asset impairment and disposal matters. It includes extensive financial data, asset impairment details, project exit and transfer specifics, accounting treatments, and audit procedures. The document references the 2021 annual financial report and ongoing audit work, with detailed disclosures on asset valuations, impairment testing, and related transactions. The length (15,000 characters) and depth of financial and operational information indicate this is a substantive financial report rather than a brief announcement or certification. The content aligns with an Audit Report / Information filing, as it focuses on audit procedures, impairment testing, and accounting treatments related to the annual financial results but is not the full Annual Report (10-K). Therefore, the appropriate classification is AR (Audit Report / Information).

关于深圳证券交易所《关注函》阶段性回复的公告
Regulatory Filings Classification · 95% confidence The document is a detailed announcement from 启迪环境科技发展股份有限公司 responding to a regulatory inquiry (关注函) issued by the Shenzhen Stock Exchange. It addresses issues related to alleged financial irregularities, audit procedures, ongoing investigations by the China Securities Regulatory Commission (CSRC), and progress on a major merger and acquisition transaction. The document includes extensive discussion of audit procedures, regulatory investigations, and company responses to regulatory requests. It is not a full annual or interim financial report, nor is it a simple announcement of a report's publication. It is also not a transcript, presentation, or voting result. The document primarily serves as a regulatory response and update on legal and compliance matters, including ongoing investigations and corrective actions. Therefore, it fits best under the category of Regulatory Filings (RNS), which is the fallback for miscellaneous regulatory announcements and compliance documents that do not fit other categories.

关于公司收到中国证券监督管理委员会立案告知书的公告
Regulatory Filings Classification · 95% confidence The document is a short announcement (510 characters) about the company receiving a formal investigation notice from the China Securities Regulatory Commission regarding suspected disclosure violations. It states the company will cooperate and continue to disclose information as required. There is no financial data, no report attached or published, and no detailed financial or management information. This fits the description of a Regulatory Filing (RNS) as it is a compliance-related announcement about a regulatory investigation, not a financial report or other specific filing type.
