Filing Released Lang Actions
恒力石化关于续聘会计师事务所的公告
Regulatory Filings Classification · 1% confidence The document is an official corporate announcement by Hengli Petrochemical’s board regarding the reappointment of an external accounting firm (audit institution) for the company’s 2026 financial report and internal control audit. It does not include the audit report itself but merely discloses the board resolution, auditor qualifications, fee arrangements, and related procedural matters. This type of notice does not fit any other specific category (e.g., it is not a management or board personnel change, not an audit report, not a financial report, and not a dividend or share transaction). Therefore it falls under the fallback category for miscellaneous regulatory disclosures.

恒力石化“提质增效重回报”专项行动2025年度评估报告暨2026年度行动方案
Management Reports Classification · 1% confidence The document is a comprehensive company announcement detailing the 2025 special ‘‘提质增效重回报’’ action plan evaluation and the 2026 action plan. It includes a review of 2025 financial performance and key business trends, strategic initiatives, shareholder return policy, governance improvements, ESG commitments, and an outlook for 2026. It is not a simple notice of a report, nor is it an earnings release or regulatory filing. Instead, it closely resembles a Management Discussion & Analysis-style report that explains results, strategies, and outlook. Thus, it fits the Management Reports category (MDA).

恒力石化关于2026年度担保计划的公告
Regulatory Filings Classification · 1% confidence The document is a public announcement (‘公告’) of Hengli Petrochemical’s 2026 annual guarantee plan, detailing board approval, proposed guarantee limits, parties to be guaranteed, and subsidiary financials. It is not a full financial report (10-K or IR), not a dividend or proxy solicitation, nor a share issue or buyback. It is a regulatory disclosure mandated by listing rules regarding external guarantees and does not fit into the more specific categories like capital raising (CAP) or M&A. Therefore, it is best classified as a general regulatory filing.

恒力石化董事会审计委员会2025年度对会计师事务所履行监督职责情况的报告
Governance Information Classification · 1% confidence The document is a standalone report by the Board Audit Committee detailing its oversight of the external auditor for the 2025 fiscal year. It describes internal governance processes, committee procedures, and compliance with corporate governance regulations rather than announcing financial results or management changes. This fits squarely into Governance Information (CGR).

恒力石化2025年年度报告摘要
Annual Report Classification · 1% confidence The document is titled '恒力石化股份有限公司2025年年度报告摘要' (Hengli Petrochemical Co., Ltd. 2025 Annual Report Summary). It contains key financial data, business highlights, shareholder information, and bond details for the fiscal year 2025. Although it is a 'summary' (摘要), it serves as the primary disclosure of the annual financial results for the company, which aligns with the definition of an Annual Report (10-K) in the context of financial reporting standards where the summary is the official public-facing version of the full annual report.

It is not an earnings release, financial report, proxy statement, or capital-raising notice but rather a routine regulatory disclosure of intended hedging activities. Therefore, it fits the fallback category for general regulatory announcements.
