Regulatory Filings Classification · 65% confidence The document is a very short snippet (only a table of inventory turnover ratios and average sales days for two fiscal years) provided via the public information platform MOPS. It does not constitute a full annual or interim report, earnings release, or any specific category (dividend notice, M&A, management changes, etc.), nor is it merely an announcement that a larger report is available. It is regulatory content in a miscellaneous filing. Therefore it falls under the general Regulatory Filings fallback category (RNS).

Regulatory Filings Classification · 75% confidence The document is a brief two-year comparative financial data table drawn from the public disclosure website (公開資訊觀測站) showing revenue, cost, gross profit, and margin changes. It is too short to be a full report (Annual Report or Quarterly Report), not an earnings release or investor presentation, and contains no announcement language about publication of a separate document. It is a routine regulatory disclosure under Taiwan’s exchange system, fitting the catch-all Regulatory Filings category.

The document is short and specific to insider share transactions, not a general financial report or announcement.

Director's Dealing Classification · 100% confidence The document is a tabular report showing details of pledged shares by a company director (吳昭宜) including the number of shares pledged, released, and cumulative pledged shares. It includes specific dates and identifies the pledgor as a director. This matches the definition of a Director's Dealing report, which covers personal share transactions by company directors and executives. The document length is short and focused solely on share pledging activity by a director, so it is not an annual report or other financial report type.
