1. Reason for Repurchase

Repurchase will be made for the purpose of, among other things, offsetting the potential dilutive effect of the conversion of the Eleventh Series Class XI Preferred Stock in consideration of the possibility that the number of shares of our common stock will increase after the commencement of the conversion period from July 1, 2008.

2. Details of Repurchase

 

  (1) Type of shares to be repurchased:

Shares of common stock of Mizuho Financial Group, Inc.

 

  (2) Aggregate number of shares to be repurchased:

Up to a maximum of 250,000 shares

 

  (3) Aggregate amount of repurchase:

Up to a maximum of 150 billion yen

 

  (4) Period of repurchase

From June 1 to November 30, 2007 (6 months)

3. Miscellaneous

We plan to cancel all the common shares repurchased.

While the resolution at this time sets up a limit for repurchasing our common shares at the aggregate amount shown above, we will continue to consider setting up additional repurchase limits and conducting share repurchases for the same purpose as described in section 1 above, based on market conditions, our earnings trend and other factors.
