Major Shareholding Notification Classification · 100% confidence The document is a disclosure about changes in shareholding percentages of the controlling shareholder and its concerted parties, specifically noting a passive dilution due to an increase in total shares from a stock option plan. It details the shareholding percentages before and after the change, confirms no direct share transactions occurred, and states that the controlling shareholder and actual controller remain unchanged. This type of announcement is a notification of changes in major shareholding levels, triggered by crossing a 1% threshold. It is not a financial report, earnings release, or management report, but a regulatory announcement about shareholding changes. Therefore, the appropriate classification is Major Shareholding Notification (MRQ). The document length and content confirm it is not a brief report publication announcement or a certification letter, but a substantive disclosure of shareholding changes.
