Regulatory Filings Classification · 75% confidence The document is a short, tabular monthly revenue summary (“查詢彙總報表”) filed on Taiwan’s Market Observation Post System (MOPS). It is a mandated regulatory disclosure of net operating revenue for the month and year-to-date. There is no specific category for monthly revenue in the taxonomy. It is not an AGM material, not a full interim or annual report, and not merely a notice of publication. It therefore falls under the fallback “Regulatory Filings” category (RNS).

This is not a report publication announcement or financial report, but an ongoing insider share transaction and holdings statement.
