The reasons the company gives

The company's own explanation, not something inferred from the numbers.

The Company established the acquisition limit to enable a flexible response based on a comprehensive assessment of the share price and other factors. In light of share price trends during the acquisition period and expanded investment opportunities aimed at business growth, the Company limited the acquisitions to part of the total number of shares and total amount authorized, and will allocate management resources while assessing the balance between shareholder returns and growth investment.
