公告本公司董事會委任永續發展委員會委員
Board/Management Information Classification · 100% confidence The document is a short announcement from a company (3622 洋華) regarding the appointment of a new member to the Sustainability Development Committee by the board of directors. It includes details such as the name of the new appointee, their background, and the effective date of the appointment. There are no financial statements, no discussion of financial results, no regulatory certifications, or any mention of reports being attached or published. The content is about a change in board committee membership, which falls under management or board information. Given the nature of the announcement, it fits best under 'Board/Management Information' (MANG). The document length is short and focused solely on this appointment, confirming it is not a full report or a report publication announcement.

Board/Management Information Classification · 95% confidence The document is very short (248 characters) and contains a table listing company code, company name, establishment date, and member names with expertise and operational information. There is no financial data, no mention of reports, no regulatory body references, or any indication of a report or announcement. The content appears to be a simple disclosure of board or committee members and their qualifications. This fits best with Board/Management Information (MANG), which covers announcements of changes or details about company board or senior management. Confidence is high due to the clear nature of the content and absence of other report types.

114年8月營業收入
Financial Supplement Data Classification · 70% confidence The document is a revenue summary report for a company named 洋華 for the period 民國114年08月 (August 2025). It contains monthly and cumulative net operating revenue figures compared to the previous year, with percentage changes and notes on accounting standards (IFRS). The document is very short (775 characters) and primarily presents summarized financial data without detailed financial statements or management discussion. It does not appear to be a full financial report like an Annual Report (10-K) or Interim Report (IR). It also does not fit categories like Earnings Release (ER) which usually highlight key financial results in narrative form, nor is it a presentation or regulatory filing. Given the nature of the data as a brief financial summary focusing on revenue figures, the best fit is Financial Supplement Data (XLSX), which covers supplementary financial data summaries, even though this is not an Excel file, the content matches the type of brief financial data summary. Alternatively, it could be considered a Regulatory Filing (RNS) as a fallback, but the content is more aligned with a financial data summary. Confidence is moderate due to the short length and summary nature.

114年8月背書保證與資金貸與
Regulatory Filings Classification · 95% confidence The document is a brief financial disclosure from a listed company, providing data on loan balances and endorsement guarantees for the current and previous months, including limits and cumulative amounts. It is short (621 characters) and contains tabular financial data but does not present a comprehensive financial report or detailed analysis. It appears to be a regulatory disclosure of financial guarantees and related party transactions rather than a full report or announcement of a meeting or vote. Given the nature and length, it fits best as a Regulatory Filing (RNS), which is a fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

114年08月董事會成員及持股
Director's Dealing Classification · 95% confidence The document contains detailed tables listing shareholdings of company insiders, including directors, managers, and major shareholders, with specific numbers of shares held and pledged. It is a disclosure of insider shareholdings and related information. There is no indication of financial results, meeting materials, voting results, or legal proceedings. The document is a report on insider shareholdings, which corresponds to Director's Dealing filings, as it reports personal share transactions or holdings by company directors and executives. The document length is about 3,084 characters, which is sufficient for such a report. Therefore, the most appropriate classification is Director's Dealing (DIRS).

114年08月內部人持股異動(事後)
Director's Dealing Classification · 95% confidence The document consists of detailed tables listing shareholdings of insiders, including directors, managers, and their related parties, with specific numbers of shares held, increases, decreases, and other related data. The content is focused on insider share transactions and holdings rather than financial results, management changes, or other corporate events. There is no indication of a full annual or quarterly report, earnings release, or meeting materials. The document is not a brief announcement but a detailed disclosure of insider shareholdings. This matches the definition of Director's Dealing (DIRS), which covers reports of personal share transactions by company directors and executives (insider trades). The document length is sufficient and the content is consistent with insider shareholding disclosures.
