臨時報告書
AGM Information Classification · 100% confidence The document is titled "臨時報告書" (Extraordinary Report/Timely Disclosure Report) and explicitly states in Section 1 that it is being submitted pursuant to Article 24-5, Paragraph 4 of the Financial Instruments and Exchange Act because resolutions were passed at the Annual General Meeting (AGM) held on March 27, 2025. Section 2 details the resolutions, specifically the election of five directors, and provides the voting results (votes for, against, abstentions, and approval percentage). This content—reporting the results of shareholder votes on board appointments following a general meeting—directly corresponds to the definition of 'Declaration of Voting Results & Voting Rights Announcements' (DVA). Although it relates to an AGM, the core purpose is reporting the *results* of the vote, not providing the meeting materials (AGM-R) or proxy information (PSI).
