115年第1季大陸投資
Regulatory Filings Classification · 85% confidence The document is a tabular schedule of the company’s investments in Mainland China (names of investee companies, amounts invested, shareholdings, recognized gains/losses, etc.). It is a statutory disclosure on the Taiwan Market Observation Post System (公開資訊觀測站). It is neither a full quarterly/annual report nor a short earnings release or management discussion; rather it is a standalone data disclosure of specific investment information. There is no specific category for mainland investment schedules, so it falls under the fallback “Regulatory Filings (RNS).”

Proxy Solicitation & Information Statement Classification · 85% confidence The document is not the annual report, financial statements, or audit report itself but is a formal notice of the 2026 Annual General Shareholders’ Meeting including meeting agenda, proxy and voting instructions, and solicitation information. This matches the definition of a Proxy Solicitation & Information Statement (PSI).

Proxy Solicitation & Information Statement Classification · 75% confidence The document is entirely focused on listing shareholders’ proxy appointment forms (‘委託書取求人彙總名單’) ahead of the company’s shareholders meeting, including dates and proxy agent details. This corresponds to materials related to proxy solicitation and information statements rather than reporting results or announcing financial data. Therefore, the appropriate classification is Proxy Solicitation & Information Statement (PSI).
