115年5月20日內部人設質解質
Director's Dealing Classification · 60% confidence The document is a regulatory disclosure listing a pledge (“設質”) of shares by the company’s chairman, detailing pledged share counts and pledgee. This is not a corporate share buyback or capital change, nor a regular financial report. It is a disclosure of an insider (director) share transaction (pledge of personal shares). Therefore it fits the Director’s Dealing category.

本公司董事會決議購入新北市汐止區崇德段土地，補充說明。
Regulatory Filings Classification · 78% confidence The document is a regulatory announcement from the company’s information observatory detailing a board resolution to purchase land in New Taipei City. It does not present financial statements (so it’s not an Interim or Annual Report), nor is it an earnings release, capital raising, share transaction, or management change notice. It is a generic disclosure of a corporate action (land acquisition) that does not fit the specific categories, making “Regulatory Filings (RNS)” the appropriate classification.

AGM Information Classification · 85% confidence The document is the official agenda for the company’s Annual General Meeting, listing the meeting time, location, report items, approval items, and procedural order. It does not contain the full annual report or voting results, but rather the meeting materials (agenda) to be presented at the AGM. This matches the definition of AGM Information (AGM-R).

Major Shareholding Notification Classification · 45% confidence The document is a tabular disclosure of the company’s top ten shareholders and their inter-relationships as of the record date.

115年年報及股東會資料 — 2026_2020_20260618F02.pdf
AGM Information Classification · 95% confidence The document is titled “股東常會議事手冊” and contains the full agenda, proposals, and attachments (financial statements, audit committee reports, profit distribution tables, company charter) for the company’s Annual General Meeting (115th year). It is clearly the set of materials provided to shareholders in connection with the AGM rather than a standalone annual report, earnings release, or proxy statement. Therefore, it matches the “AGM Information” category.
