2025年一季度报告
Interim / Quarterly Report Classification · 100% confidence The document is titled '2025 年第一季度报告' which translates to '2025 First Quarter Report'. It contains detailed financial data including income statement, balance sheet, cash flow statement, and explanations of financial changes for the first quarter of 2025. It explicitly states it is a quarterly report and is unaudited. The content includes comprehensive financial statements and analysis for a period shorter than a full fiscal year, consistent with an Interim / Quarterly Report. There is no indication that this is an announcement of a report or a certification letter, so it is not RPA or RNS. Therefore, the document fits the definition of an Interim / Quarterly Report (IR).

联储证券关于通源石油2024年度募集资金存放与使用情况的专项核查意见
Audit Report / Information Classification · 95% confidence The document is a detailed report on the 2024 annual special audit opinion regarding the storage and use of raised funds by Tongyuan Petroleum Technology Group Co., Ltd. It includes extensive financial data on fundraising amounts, usage, balances, regulatory compliance, and audit opinions by an accounting firm. The content focuses on the management and use of capital raised through stock issuance, with tables showing detailed fund usage and balances, and includes an auditor's verification report. This matches the characteristics of an Audit Report / Information filing, which covers standalone audit reports and applied accounting principles related to specific financial aspects, here specifically the use of raised funds. The document is lengthy (15,000 characters) and contains substantive financial data and audit opinions, not merely an announcement or certification. Therefore, the appropriate classification is AR (Audit Report / Information). FY 2024

It states that the 2024 Annual Report and summary will be disclosed on April 11, 2025, on the designated information disclosure website. The text explicitly mentions the report will be published later and advises investors to check it. There is no actual financial data or detailed report content here, only a notice about the upcoming report publication. According to the 'Menu vs Meal' rule, this is a Report Publication Announcement (RPA), not the Annual Report (10-K) itself.

联储证券关于通源石油2021年以简易程序向特定对象发行股票持续督导总结报告书
Capital/Financing Update Classification · 95% confidence The document is titled as a "持续督导总结报告" (Continuous Supervision Summary Report) by the sponsoring institution 联储证券股份有限公司 regarding a specific stock issuance by 通源石油科技集团股份有限公司 in 2021. It details the continuous supervision activities, compliance with regulatory requirements, information disclosure, and the use of raised funds. The document includes detailed descriptions of the sponsor's duties, regulatory compliance, and follow-up on issues raised by the securities regulator. It is not a full annual or interim financial report, nor is it an earnings release or a simple announcement. It is a specialized report related to the continuous supervision of a specific capital raising event, which aligns with the category of Capital/Financing Update (CAP). The document length (6364 characters) and content indicate it is a substantive report, not just an announcement or certification. Therefore, the best fitting classification is CAP with high confidence.

董事会关于2024年度审计机构履职情况评估报告
Audit Report / Information Classification · 95% confidence The document is titled as an evaluation report on the performance of the audit firm for the fiscal year 2024. It details the qualifications, independence, quality control, and overall assessment of the audit firm engaged by the company. It does not contain actual financial statements or detailed financial results but rather an assessment of the audit firm's work and compliance with standards. This fits the definition of an Audit Report / Information (AR), which includes standalone audit reports and evaluations related to audit processes, excluding full annual reports. The document length is 2901 characters, which is consistent with a detailed report but not a full annual report. Therefore, the appropriate classification is AR with high confidence. FY 2024

关于续聘2025年度审计机构的公告
Audit Report / Information Classification · 95% confidence The document is an announcement regarding the reappointment of the audit firm for the fiscal year 2025. It details the qualifications, background, and integrity of the audit firm, the procedures followed by the audit committee, board of directors, and supervisory board, and states that the reappointment is subject to shareholder approval. The document does not contain any financial statements or audit reports themselves, but rather is a formal announcement about the audit firm engagement for the upcoming year. The document length is 3255 characters, which is relatively short and consistent with an announcement rather than a full audit report. Therefore, this document fits the category of Audit Report / Information (AR) as it relates to audit matters but is not a full annual report or audit report itself. It is not a Regulatory Filing (RNS) because it is a substantive announcement about audit firm reappointment, not a certification or miscellaneous filing. FY 2025
