1. Secondary Offering by way of Over-Allotment

The Secondary Offering by way of Over-Allotment described in “2. Secondary Offering of Shares (Secondary Offering by way of Over-Allotment)” above is a secondary offering of shares of common stock of the Company to be conducted by the Lead Manager in conjunction with “1. Secondary Offering of Shares (Secondary Offering by way of Purchase and Subscription by the Underwriters)” above, taking into account market demand and other conditions, with up to 735,400 shares of common stock of the Company to be borrowed from certain shareholder(s). The number of shares to be offered in the Secondary Offering by way of Over-Allotment is planned to be 735,400 shares; provided, however, as such planned number of shares is the maximum number of shares to be offered, such number may decrease or the Secondary Offering by way of Over-Allotment itself may be canceled entirely, depending on market demand and other conditions.

When conducting the Secondary Offering by way of Over-Allotment, the Lead Manager will be granted the right (the “Greenshoe Option”) to obtain shares of common stock of the Company up to the number of shares to be sold in the Secondary Offering by way of Over-Allotment in addition to the shares for the Secondary Offering by way of Purchase and Subscription by the Underwriters,

with the exercise period being from the delivery date of the Secondary Offering by way of Purchase and Subscription by the Underwriters and the Secondary Offering by way of Over-Allotment to Friday, November 21, 2025.

The Lead Manager may also purchase shares of common stock of the Company (the “Syndicate Cover Transactions”) on the Tokyo Stock Exchange, Inc., up to the number of shares in the Secondary Offering by way of Over-Allotment, for the purpose of returning the shares of common stock of the Company (the “Borrowed Shares”) borrowed by it from certain shareholder(s) during the period from (i) the day immediately following the last day of the subscription period for the Secondary Offering by way of Purchase and Subscription by the Underwriters and the Secondary Offering by way of Over-Allotment to (ii) Friday, November 21, 2025 (the “Syndicate Cover Transaction Period”). All of the shares of common stock of the Company to be purchased by the Lead Manager through the Syndicate Cover Transactions will be used to return the Borrowed Shares. During the Syndicate Cover Transaction Period, the Lead Manager may decide not to conduct any Syndicate Cover Transactions or may decide to terminate the Syndicate Cover Transactions before the number of shares purchased reaches the number of shares in the Secondary Offering by way of Over-Allotment.

Furthermore, the Lead Manager may conduct stabilizing transactions in relation to the Secondary Offering by way of Purchase and Subscription by the Underwriters and the Secondary Offering by way of Over-Allotment. The shares of common stock of the Company purchased through such stabilizing transactions may be used, in part or in whole, to return the Borrowed Shares.

The remaining Borrowed Shares after being acquired through the Syndicate Cover Transactions and stabilization transactions and allocated for the return will be returned by the Lead Manager by exercising the Greenshoe Option.
