    The Disposal of Treasury Shares is being conducted in connection with the introduction of the ESOP Trust, whereby Ono will dispose of its treasury shares to The Master Trust Bank of Japan, Ltd. (Stock Grant ESOP Trust account), the co-trustee of the ESOP Trust agreement that Ono enters into with Mitsubishi UFJ Trust and Banking Corporation (“the Trust Agreement”).

  3. Basis of Calculation and Specific Details of the Disposal Price

    In light of recent stock price trends and to eliminate arbitrariness, the disposal price has been set at 2,435.5 yen, which is the closing price of Ono’s shares on the Tokyo Stock Exchange, Inc. (“Tokyo Stock Exchange”) on the business day preceding the date of the Board of Directors’ resolution concerning the Disposal of Treasury Shares (March 4, 2026), in accordance with the “Guidance Concerning Handling of Allotment of New Shares to Third Party, Etc.” established by the Japan Securities Dealers Association. The price was adopted because it represented the market price immediately prior to the Board of Directors’ resolution and was deemed highly objective and reasonable as a basis for calculation.
    All Audit and Supervisory Board Members of Ono (consisting of four members, including two Outside Audit & Supervisory Board Members) expressed their opinions that the basis for calculating the disposal price is reasonable, and that it does not particularly fall under an arbitrarily favorable pricing category.

  4. Procedure Required by the Corporate Code of Conduct

    The Disposal of Treasury Shares does not require the procurement of an opinion from an independent third party or require procedures for confirming the intent of shareholders, which are provided for under Article 432 of the Securities Listing Regulations of the Tokyo Stock Exchange, because the dilution ratio of the disposal is less than 25% and the disposal does not involve a change in controlling shareholder.
