The meaning of shareholder registration date refers to the date when a listed company issues share rights to its shareholders. Before this day, shareholders holding the company's shares enjoy the corresponding rights of the company's issued shares in accordance with the company's articles of association. On the shareholder registration date, shareholders need to submit relevant shareholder identification documents to the company in accordance with the provisions of the company's articles of association so that the company can confirm their shareholder identity and rights.

The main purpose of the shareholder registration date is to ensure that all shareholders can equally participate in the company's decision-making and dividend distribution. After the shareholder registration date, the company will distribute share rights, and shareholders can receive their own share rights with relevant identification documents. These rights may include dividends, share repurchases, voting rights, etc.

It should be noted that on the shareholder registration date, shareholders need to provide accurate identification documents to the company so that the company can confirm their shareholder identity and rights. If the proof documents provided by shareholders are inaccurate or missing, it may affect their enjoyment of rights. Therefore, shareholders holding the company's shares should before the shareholder registration date, understand the relevant regulations and requirements, and be prepared with the required identification documents.
