2. Status and Evaluation of Initiatives to Comply with Listing Maintenance Criteria

In the "Plan to Meet the Continued-Listing Criteria for the Prime Market" disclosed on October 27, 2022 (available only in Japanese), the Company disclosed that the main reason for non-compliance with the criteria for "Market Capitalization of Tradable Shares" was a decline in stock prices due to sluggish business performance, which continued until the fiscal year ending July 31, 2024. However, as a result of the success

of various initiatives put forth in our "Notice Regarding Progress of Plan to Meet the Continued-Listing Criteria for the Prime Market and Partial Changes in the Plan" disclosed on October 10, 2024 (available only in Japanese), the Company met all the criteria for maintaining its listing on the Prime Market as of July 31, 2025.

We placed our top priority for the previous fiscal year to end on achieving our performance forecasts, with initiatives spearheaded by the holding company in the pursuit of a profit-oriented strategy, including a comprehensive overhaul of the meeting bodies for management discussion and decision-making, as well as the management of forecasting and investment profitability. We also focused on stable and flexible shareholder returns. We formulated and disclosed capital allocation based on the medium-term business plan (FY2025-FY2028), established a new shareholder benefit plan, and acquired and retired treasury stock. As a result, the number of tradable shares and the stock price increased, and we exceeded the 10 billion JPY criteria for the "Market Capitalization of Tradable Shares", enabling us to meet all the criteria for our continued listing on the Prime Market. The Company remains committed to actively implementing the medium-term business plan, focusing on sustainable growth and increasing our corporate value as a Prime Market-listed company.
