代子公司環旭電子(股)公司公告董事會決議召開2025年年度 股東會
Proxy Solicitation & Information Statement Classification · 1% confidence The document is an official notice from 3711 日月光投控 announcing that its subsidiary’s board has resolved to convene the 2025 annual shareholders’ meeting, including date, location and detailed agenda items for reports, approvals, discussions and elections. This is a solicitation of proxies and information statement to shareholders ahead of the meeting. It is not the AGM presentation itself nor post‐meeting voting results, but the pre‐meeting notice with full agenda. Therefore, it matches the Proxy Solicitation & Information Statement category.
2026-04-03 Chinese
代子公司環旭電子(股)公司公告董事會決議調整2025年股份 回購方案
Transaction in Own Shares Classification · 1% confidence The document is an announcement by a listed company and its subsidiary’s board resolving to adjust the 2025 share repurchase plan, detailing the buyback price ceiling, intended use of repurchased shares, and capital cancellation considerations. This is not a regular report but a corporate action notice concerning the company buying back its own shares. It matches the definition for Transaction in Own Shares (POS).

代子公司日月光半導體製造(股)公司、日月光電子 (股)公司公告配合檢調單位調查《廢棄物清理法》 案件說明
Legal Proceedings Report Classification · 1% confidence The document is a stock exchange regulatory announcement by company 3711 and its subsidiaries cooperating with a criminal investigation by the Tainan District Prosecutors Office regarding waste disposal law compliance.

公告本公司民國114年第4季海外財務報告因適用兩地 會計原則不一致之差異調節內容說明
Regulatory Filings Classification · 1% confidence The document is a mandatory regulatory disclosure on Taiwan’s public information platform (“公開資訊觀測站”) by company 3711, detailing the reconciliation of financial statement line items between Taiwan IFRS and IFRS for the 4th quarter/Year 114. It does not present a full interim/quarterly report nor an investor presentation; rather it is a specific regulatory announcement of accounting‐standards differences. No other more specific category applies, so this falls into the general "Regulatory Filings" fallback.

代子公司矽品科技(蘇州)有限公司公告取得營業用機器設備達十億元
Regulatory Filings Classification · 1% confidence The document is a Taiwanese “公開資訊觀測站” regulatory disclosure by company 3711 日月光投控 announcing its subsidiary’s acquisition of operating machinery equipment worth over NTD 1.3 billion. It provides detailed transaction terms (asset type, dates, parties, amounts, payment method) under ‘符合條款 第20款’, which corresponds to an asset acquisition announcement on the market disclosure system. This is not a financial report (10-K, IR, ER), not an AGM or proxy, not a financing or dividend update, and not a share issuance or repurchase. Therefore it falls into the fallback “Regulatory Filings” category.
