Note: The requirement for adoption of the proposals is as follows:

•

Approval of a majority of the voting rights held by the shareholders present at the meeting who hold in aggregate not less than one-third (1/3) of the voting rights of the shareholders entitled to exercise their voting rights is required for the adoption of Proposal 1.

•

Approval of not less than two-thirds (2/3) of the voting rights held by the shareholders present at the meeting who hold in aggregate not less than one-third (1/3) of the voting rights of the shareholders entitled to exercise their voting rights is required for the adoption of Proposal 2 and Proposal 3.

Reason for not counting a portion of the voting rights of the shareholders present at the ordinary general meeting of shareholders

Since the adoption or rejection of all the proposals was conclusively decided by the exercise of the voting rights prior to the date of this general meeting and the number of voting rights of shareholders in attendance at this general meeting, whose approval or disapproval Mizuho Financial Group was able to confirm, the number of voting rights for approval, disapproval and abstention shown in the above table does not include a portion of those of the shareholders present at the general meeting.
