本公司受邀參加野村證券舉辦之投資人說明會
Regulatory Filings Classification · 85% confidence The document is a disclosure filed on Taiwan’s Market Observation Post System announcing that the company has been invited to participate in an investor briefing organized by Nomura Securities. It provides event details (date, time, location, summary) but contains no actual financial statements, presentation slides, or substantive report content. This is an announcement of a corporate event rather than a report itself, fitting the fallback category for miscellaneous regulatory announcements. Therefore, it should be classified as a Regulatory Filing (RNS).
