Filing Released Lang Actions
四方光电2025年度内部控制评价报告
Audit Report / Information Classification · 1% confidence The document is a standalone internal control evaluation report (“内部控制评价报告”) for the fiscal year ending December 31, 2025. It focuses exclusively on the company’s internal control framework, evaluation conclusions, defect identification standards and remediation status, without containing full financial statements or operational results typical of an Annual Report (10-K) or an Interim Report (IR). It is not an announcement (“RPA”), not an earnings release, not a governance charter, and not a management discussion and analysis of results. As a standalone audit-related disclosure on internal control effectiveness, it best fits the Audit Report / Information category (AR).

四方光电2025年度内部控制审计报告
Audit Report / Information Classification · 1% confidence The document is an internal control audit report (“内部控制审计报告”) issued by a licensed accounting firm, containing audit opinions on the effectiveness of the company’s internal controls over financial reporting for the year ending December 31, 2025. It is a standalone audit report, not an annual report, earnings release, or management presentation. Therefore it fits the “Audit Report / Information” category.
2026-04-17 Chinese
四方光电2025年年度股东会通知
Proxy Solicitation & Information Statement Classification · 1% confidence The document is a notice of the 2025 Annual General Meeting (AGM) sent to shareholders, detailing meeting logistics, agenda items for shareholder votes, proxy voting instructions, and proxy form attachments. This fits the definition of a Proxy Solicitation & Information Statement (materials sent to shareholders to provide information and request votes for meetings), rather than the AGM presentation itself or the voting results. Therefore, the appropriate category is PSI.

四方光电董事会审计委员会对会计师事务所履行监督职责情况报告
Audit Report / Information Classification · 1% confidence The document is a formal report issued by the board’s audit committee describing its oversight of the external audit firm’s qualifications, independence, audit procedures, and performance for the fiscal year 2025. It is not the company’s full annual report (10-K), nor an announcement of a shareholder meeting or dividend, but a standalone audit-related disclosure. The most fitting category is Audit Report/Information (AR).
2026-04-17 Chinese
四方光电关于2026年度日常关联交易预计的公告
Regulatory Filings Classification · 1% confidence The document is an official announcement by 四方光电股份有限公司 regarding its forecast of daily related‐party transactions for fiscal 2026. It is not an annual or interim financial report, earnings release, M&A notice, dividend notice, board change announcement, or any category explicitly listed. This type of connected‐party transaction disclosure is a regulatory corporate filing that does not fit the other more specific categories and thus falls under the fallback “Regulatory Filings” category (RNS).
2026-04-17 Chinese
四方光电2025年度独立董事述职报告（许贤泽）
Governance Information Classification · 1% confidence The document is the annual performance report (‘述职报告’) of an independent director, detailing board and committee attendance, governance oversight, compliance with laws/regulations, and internal governance practices. It is not a financial statement (10-K/IR/MDA), not an appointment notice (MANG), nor a simple announcement (RPA/RNS). Instead, it is a standalone governance disclosure about board structure, procedures, and director duties, matching the “Governance Information” category (CGR).
