Filing Released Lang Actions
115年06月僑外投資持股
Regulatory Filings Classification · 82% confidence The document is a regulatory disclosure table from the Taiwan public information observatory detailing foreign and mainland China investor shareholdings as of a given date. It is not an earnings release, management discussion, or capital transaction notice, nor is it a specific threshold-crossing major shareholding by an individual. It is a compliance/regulatory filing for public disclosure. Therefore, it falls under the general Regulatory Filings category (RNS).

115年05月內部人持股異動(事後)
Director's Dealing Classification · 90% confidence The document is a disclosure of insider shareholdings and transactions by directors, chairperson, executive officers, their spouses and minor children across the reporting period, showing increases and decreases in holdings. This matches the description of personal share transactions by company directors and executives. Therefore, it is classified as a Director's Dealing report.

115年05月董事會成員及持股
Director's Dealing Classification · 85% confidence The document is a mandatory disclosure of internal persons’ (directors, supervisors, executives) shareholdings and pledges, detailing each insider’s current and initial holdings. This fits the definition of a Director’s Dealing (insider shareholding/trades) report rather than an AGM material, financial report, or simple publication notice. Thus it should be classified as DIRS.

115年5月背書保證與資金貸與
Regulatory Filings Classification · 85% confidence The document contains only a notice in Chinese stating no data is available and references a public information site, with no substantive content or indication of any specific report, transaction, or announcement. It does not present financial statements, management discussion, voting results, or any standard filing type. Therefore it falls into the fallback category of miscellaneous regulatory filings.
2026-06-03 Chinese
115年5月營業收入
Regulatory Filings Classification · 30% confidence The document is a routine monthly revenue summary filed on Taiwan’s MOPS (“公開資訊觀測站”) for May of fiscal year 115, providing net sales data and IFRS footnotes. It is a short regulatory announcement with actual revenue figures for a sub-quarter period, not a full interim or annual report, nor a call transcript or management discussion. There is no detailed financial statements or narrative; it’s simply a compliance data disclosure. This fits “Regulatory Filings (RNS)” as a miscellaneous routine filing.

There is no financial report content or earnings data; it is solely AGN meeting logistics and proxy materials. Therefore, it fits the Proxy Solicitation & Information Statement category (PSI).
