关于续聘会计师事务所的公告
Regulatory Filings Classification · 95% confidence The document is an announcement by Jiangsu DiAo Microelectronics Co., Ltd. regarding the reappointment of an accounting firm (Lixin CPA Firm) as the company's auditor for the year 2023. It details the qualifications, independence, and integrity of the accounting firm and the audit team, as well as the audit fees and the approval process by the audit committee, independent directors, board of directors, and supervisory board. The document does not contain any financial statements or audit reports themselves but is a formal announcement about the appointment of the auditor. The document length is 3283 characters, which is relatively short and consistent with an announcement rather than a full audit report. Therefore, this document fits best into the category of Audit Report / Information (AR) as it relates to audit information but is not a full annual report or audit report itself. However, since it is an announcement of auditor appointment and not the audit report or results, it is more appropriate to classify it as Regulatory Filings (RNS) because it is a regulatory announcement about auditor appointment and related information, not the audit report itself.

2022年年度报告
Annual Report Classification · 100% confidence The document is titled '2022 年年度报告' which translates to '2022 Annual Report'. It contains detailed sections typical of an annual report such as company overview, financial data, management discussion and analysis, audit report mention, and comprehensive financial and operational information. The document length is substantial (15,000 characters), indicating it is the full report rather than a brief announcement. The presence of audited financial statements and management analysis confirms it is the official yearly report covering company activity and full financial performance. Therefore, the document fits the definition of an Annual Report (10-K).

中信建投证券股份有限公司关于江苏帝奥微电子股份有限公司2022年度募集资金存放与实际使用情况的专项核查意见
Audit Report / Information Classification · 95% confidence The document is a detailed report from CITIC Securities regarding the 2022 annual special audit opinion on the deposit and actual use of raised funds by Jiangsu Di'ao Microelectronics Co., Ltd. It includes specific financial figures about the amount raised, usage, balance, investment projects, cash management, and compliance with regulatory requirements. The document references regulatory guidelines and includes an auditor's conclusion on the use of raised funds. It is a comprehensive audit-related report focusing on the use and management of funds raised through an IPO, with detailed financial data and audit opinions. This fits the category of an Audit Report / Information (AR), as it is a standalone audit report on a specific aspect (funds raised and usage) rather than a full annual report or other types of filings. The document length (9569 characters) and content confirm it is a full report, not just an announcement or certification. Therefore, the correct classification is AR with high confidence.

第一届监事会第十三次会议决议公告
Regulatory Filings Classification · 95% confidence The document is a detailed announcement of resolutions passed at the 13th meeting of the first Supervisory Board of Jiangsu DiAo Microelectronics Co., Ltd. It includes multiple agenda items such as approval of the 2022 financial statements, 2023 financial budget, profit distribution plan, supervisory board work report, auditor reappointment, use of idle funds, and approval of the 2022 annual report and 2023 Q1 report. The document is not the reports themselves but resolutions approving or submitting these reports to the shareholders' meeting. It also references multiple related announcements published separately on the Shanghai Stock Exchange website. The document is a formal meeting resolution announcement rather than the actual financial or audit reports. Therefore, it fits best under the category of Regulatory Filings (RNS), which is the fallback for regulatory announcements and meeting resolutions that do not constitute the actual reports themselves.

第一届董事会第十八次会议决议公告
Board/Management Information Classification · 95% confidence The document is a detailed announcement of resolutions passed at the 18th meeting of the first board of directors of Jiangsu DiAo Microelectronics Co., Ltd. It includes approvals of various reports such as the 2022 financial statements, 2023 budget, profit distribution plan, board work report, independent directors' report, audit committee report, and others. It also discusses proposals to be submitted to the shareholders' meeting, including the 2022 annual report and 2023 first quarter report. The document is a formal board meeting resolution announcement, not the actual reports themselves. It contains no full financial statements or detailed financial data but references reports published elsewhere (on the Shanghai Stock Exchange website). The document is primarily about board decisions and management reports to be submitted to shareholders. Therefore, it fits best under Board/Management Information (MANG), as it announces board meeting resolutions and management-related decisions.

关于增设募集资金专用账户的公告
Capital/Financing Update Classification · 95% confidence The document is an announcement by Jiangsu DiAo Microelectronics Co., Ltd. regarding the addition of a dedicated fundraising account. It details the company's fundraising activities, references regulatory approvals from the China Securities Regulatory Commission, and discusses the management and use of the raised funds. The document is a formal announcement about the establishment of a new fundraising account and related regulatory compliance, rather than a full financial report or audit. It does not contain financial statements or detailed financial analysis but focuses on capital management and regulatory adherence. Therefore, it fits best under the category of Capital/Financing Update (CAP). The document length is under 5,000 characters and is not merely announcing the publication of a report but is itself the announcement of a financing-related update.
