Notice Regarding the Results of the Repurchase of Own Shares via ToSTNeT-3

MITSUI-SOKO HOLDINGS Co., Ltd. (the "Company") hereby announces that the Company has executed the repurchase of its own shares (the "Share Repurchase") as notified on February 6, 2026, as noted below.

In addition, based on the result of the Share Repurchase, the Company has announced the progress of the disclosure relating to the 1st series of ASR share options and 2nd series of ASR share options issued through third-party allotment based on a resolution at the Board of Directors meeting held on February 6, 2026. For details, please refer to "(Progress regarding the previous disclosure) Notice Regarding Repurchase of Own Shares Through the Off-Auction Own Share Repurchase Trading (ToSTNeT-3) System, and Issuance of 1st Series Share Options and 2nd Series Share Options Through a Third Party Allotment (Repurchase of Own Shares Through a Facility Share Repurchase (Accelerated Share Repurchase ("ASR")))" separately announced today.

  1. Purpose of Share Repurchase

    Under the "Medium-term Management Plan 2022" (covering fiscal years ending March 31, 2023 to March 31, 2027), the Company aims to maintain the high level of capital efficiency. This is based on its policy of executing investments for sustainable growth and paying flexible dividends linked to performance, with an annual dividend payout ratio of 30%.

    After comprehensively considering the Company's financial position, business plans, and capital market expectations, the Company has decided to implement the Share Repurchase. This decision reflects the judgment that reconsidering the capital allocation toward the final business year of the Medium-term Management Plan and using a portion of those funds to enhance shareholder returns will help increase shareholder value. In addition, at its Board of Directors' meeting held on February 6, 2026, the Company has resolved to execute the Share Repurchase to improve capital efficiency and enhance shareholder returns, as it believes that carrying out the Share Repurchase by partially adopting an accelerated share repurchase ("ASR"), which enables it to implement the Share Repurchase on a substantial scale immediately, will further solidify its commitment to shareholder returns and ultimately contribute to a cycle of enhancing corporate value.
