Filing Released Lang Actions
115年年報及股東會資料 — 2026_8162_20260528F17.pdf
Major Shareholding Notification Classification · 60% confidence The document is a detailed table of the top ten shareholders, their share counts and percentages, and their related‐party relationships. This is a periodic regulatory disclosure of share ownership structure rather than an earnings release, management commentary, or capital raising announcement. It does not represent a full annual or interim financial report, a call transcript, or a corporate action such as a dividend or M&A. Accordingly, it best fits the “Major Shareholding Notification” category for reporting shareholding details.
