Filing Released Lang Actions
公告本公司114年第三季合併財務報告董事會召開日期
Regulatory Filings Classification · 95% confidence The document is a short announcement (536 characters) from a company (2340 台亞) stating the date of the board meeting to be held on 114/11/05 to discuss the third quarter consolidated financial report for the year 114. It does not contain the financial report itself but announces the upcoming board meeting and the expected discussion of the quarterly financial report. This fits the category of a Regulatory Filing (RNS) as it is a general regulatory announcement about the board meeting and financial report timing, not the report itself or detailed financial data.

代子公司積亞半導體股份有限公司公告114年現金增資延長 特定人繳款期間
Capital/Financing Update Classification · 95% confidence The document is a short announcement (905 characters) from a listed company (2340 台亞) regarding an extension of the payment period for a cash capital increase by its subsidiary (積亞半導體股份有限公司). It details the adjustment of the subscription period and authorization by the board chairman. There are no financial statements or detailed financial analysis present, and the document is primarily an update on a capital increase process. Given the short length and nature of the content, it is not a full capital/financing report but an announcement related to capital changes. Therefore, the appropriate classification is 'Capital/Financing Update' (CAP).

114年9月背書保證與資金貸與
Capital/Financing Update Classification · 90% confidence The document contains financial data related to loan balances, endorsements, and guarantees for the company and its subsidiaries for a specific month (September 2025). It is a short report with tabulated financial figures but does not include comprehensive financial statements or detailed analysis. It appears to be a regulatory disclosure of financing-related information rather than a full financial report or announcement of a report. Given the nature of the data (funding, guarantees, and credit limits), it fits best under Capital/Financing Update (CAP). The document length is short but contains substantive financial data related to capital and financing activities, so it is not a mere announcement or certification.

114年9月營業收入
Interim / Quarterly Report Classification · 90% confidence The document is a summary report of monthly and cumulative net operating revenue figures for a company named 台亞, presented in a tabular format with explanations about accounting standards and reporting practices. It contains financial data for a specific month and year (民國114年09月, which corresponds to 2025), including comparisons to the previous year. The document is short (772 characters) and focuses on revenue figures and notes on accounting standards (IFRS). It does not contain comprehensive financial statements or detailed analysis typical of an Interim/Quarterly Report (IR) or Annual Report (10-K). It is more of a periodic financial summary or revenue report. Given the nature of the data and the length, this fits best as an Interim / Quarterly Report (IR), since it provides substantive financial data for a period shorter than a full fiscal year, not just an announcement or a brief fact sheet. Therefore, the classification is IR with high confidence.

114年09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, officers, and their related parties. It shows the number of shares held, changes in holdings, and classifications of shares for various insiders. There is no indication of financial statements, earnings data, or management discussion. The content is focused on insider shareholdings and transactions. This matches the definition of Director's Dealing (DIRS), which reports personal share transactions by company directors and executives (insider trades). The document length is sufficient and contains substantive data, not just an announcement or certification. Therefore, the appropriate classification is DIRS.

114年09月董事會成員及持股
Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings by insiders and related parties of the company 台亞半導體股份有限公司, including directors, independent directors, and senior management. It lists current holdings, pledged shares, and related party holdings. The document is relatively short (2951 characters) and focuses on insider shareholdings rather than financial results, management changes, or meeting materials. This type of document corresponds to a Director's Dealing report, which discloses personal share transactions or holdings by company directors and executives. There is no indication of financial statements, earnings, or meeting results. Therefore, the appropriate classification is Director's Dealing (DIRS).
