公告本公司114年第一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 114/05/05 to discuss the first quarter consolidated financial report for the year 114. It is not the financial report itself but a notice about the board meeting and the upcoming report. The document does not contain any financial data or detailed analysis, only the announcement of the meeting date and the report to be discussed. According to the 'Menu vs Meal' rule, this is an announcement about a report, not the report itself. Therefore, the appropriate classification is Regulatory Filings (RNS), as it is a general regulatory announcement that does not fit other specific categories.

澄清媒體報導
Regulatory Filings Classification · 95% confidence The document is a short announcement (749 characters) from a listed company (台亞半導體股份有限公司) clarifying a media report about its operational performance and growth expectations. It explicitly states that the financial data should be based on the company's official announcements and that the media report is speculation. There is no detailed financial data, no full report, no financial statements, or comprehensive analysis. The document serves as a clarification or regulatory announcement rather than a full financial report or earnings release. Given the short length and nature of the content, it fits best as a Regulatory Filing (RNS), which is a fallback category for miscellaneous regulatory announcements that do not fit other specific categories.

Investor Presentation Classification · 95% confidence The document is titled 'Taiwan-Asia Semiconductor Corporation Investor Conference' and dated 2025/4/10. It contains a detailed presentation including company overview, strategy, revenue figures, technology roadmap, program updates, and core values. The content is structured as a slide presentation with forward-looking statements and strategic plans, typical of investor presentations. There are no indications of it being a formal financial report like an Annual Report (10-K) or Interim Report (IR), nor is it a transcript of a call or a regulatory filing. The length (9658 characters) and detailed content support it being a full investor presentation rather than a brief announcement or certification. Therefore, the document best fits the category of an Investor Presentation (IP).
