2021年度独立董事述职报告（马冠生）
Board/Management Information Classification · 95% confidence The document is titled as an "Independent Director's Work Report" for the year 2021, detailing the independent director's attendance at meetings, opinions on board resolutions, committee work, and efforts to protect investor rights. It is a narrative report on the independent director's duties and activities rather than a financial report or regulatory filing. The document length is 2236 characters, which is relatively short and focused on the director's report rather than financial data or audit results. This type of document fits best under the category of Board/Management Information (MANG), as it relates to the activities and responsibilities of a board member rather than financial statements or audit reports.

2021年年度募集资金存放与使用情况的专项报告
Capital/Financing Update Classification · 95% confidence The document is titled as a "募集资金存放与使用情况专项报告" which translates to a "Special Report on the Storage and Use of Raised Funds" for the year 2021. It details the amount of funds raised through a public offering, the usage of these funds, the balance remaining, and compliance with regulatory requirements from the China Securities Regulatory Commission and Shenzhen Stock Exchange. The document includes detailed tables showing the use of funds, project progress, and the closing of special accounts related to the raised funds. This type of report is specifically focused on the management and use of capital raised by the company, which aligns with the definition of a Capital/Financing Update (CAP) filing. It is not an annual report, earnings release, or other types of filings. The document length is over 5,000 characters and contains substantive financial data about capital usage, so it is not a mere announcement or certification. Therefore, the correct classification is CAP with high confidence.
2022-02-28 Chinese
2021年度内部控制自我评价报告
Audit Report / Information Classification · 95% confidence The document is titled '年度内部控制自我评价报告' which translates to 'Annual Internal Control Self-Evaluation Report' for the year ending December 31, 2021. It discusses the company's internal control evaluation, including financial and non-financial internal control effectiveness, defect identification standards, and remediation status. The content is focused on internal control evaluation and related governance, not a full annual financial report or audit report. It is a standalone report on internal control self-assessment, which aligns with the definition of an Audit Report / Information (AR) as it includes applied accounting principles and internal control evaluation results but is not a full annual report (10-K). The document length is 8638 characters, sufficient for a substantive report. Therefore, the classification is AR with high confidence. FY 2021
2022-02-28 Chinese
2021年年度报告摘要
Annual Report Classification · 100% confidence The document is titled as the "2021 Annual Report Summary" of 烟台正海生物科技股份有限公司, indicating it is a summary of the full annual report. It contains detailed financial data for the year 2021, including total assets, net profit, earnings per share, and quarterly financial data. It also discusses business operations, product lines, market conditions, and company achievements during the year. The presence of audited financial statements and comprehensive business and financial information confirms this is an annual report document. The document length (7,218 characters) and content depth support classification as an Annual Report rather than a brief announcement or summary notice. Therefore, the appropriate classification is Annual Report (10-K). FY 2021
2022-02-28 Chinese
2021年年度报告及摘要披露提示性公告
Report Publication Announcement Classification · 100% confidence The document is a short announcement (462 characters) titled as a '提示性公告' (indicative announcement) regarding the company's 2021 Annual Report and its summary. It states that the full annual report and summary were approved by the board and have been disclosed on the official disclosure website. The document does not contain the actual annual report or financial data but rather informs investors about the availability of the report elsewhere. According to the 'MENU VS MEAL' rule, such a short notice announcing the publication of a report is classified as a Report Publication Announcement (RPA), not the Annual Report (10-K) itself.
2022-02-28 Chinese
2021年度监事会工作报告
Management Reports Classification · 95% confidence The document is titled '监事会工作报告' which translates to 'Supervisory Board Work Report' for the year 2021. It details the supervisory board's activities, meetings, oversight of financial and internal control matters, and plans for 2022. It references specific meetings and resolutions related to financial reports and internal controls but does not itself contain full financial statements or detailed financial data. The document is relatively short (2753 characters) and focuses on supervisory board work rather than presenting a full annual report or audit report. It is not an announcement of a report publication but a report on supervisory board activities. This type of document aligns best with Management Reports (MDA), which include management's explanation of business trends, oversight, and outlook, rather than the full Annual Report (10-K) or Audit Report (AR).
