Footnote F1

On June 16, 2026, Ketan Seth, the former Chief Executive Officer of Blue Acquisition Corp. (the "Issuer") (a position from which Mr. Seth resigned as of June 9, 2026), resigned from his position as the managing member of Blue Holdings Management LLC ("BHM"), the managing member of Blue Holdings Sponsor LLC ("Sponsor"), and forfeited and surrendered to BHM any and all rights, tile or interest in and to any membership units of BHM and any securities of the Issuer, including, without limitation, any right, title or interest to or in any securities of the surviving public company upon and after the consummation (the "Closing"), if any, of the proposed business combination transaction between the Issuer and Blockfusion USA, Inc. Upon the resignation and forfeiture by Ketan Seth, he owns no Class A ordinary shares, Class B ordinary shares or any other securities convertible into Class A or Class B ordinary shares of the Issuer.

Footnote F2

Reflects the 391,000 Class A ordinary shares of the Issuer that are included in the 391,000 private placement units of the Issuer purchased by Sponsor. Each private placement unit was purchased for $10 per unit and consists of one Class A ordinary share and one right to receive one-tenth (1/10) of one Class A ordinary share upon consummation of the Issuer's initial business combination.

Footnote F3

Represents the 39,100 Class A ordinary shares, which may be acquired by Sponsor upon the conversion of 391,000 rights (included in the Sponsor's private placement units) upon consummation of the Issuer's initial business combination. As described in the Registration Statement on Form S-1 for the initial public offering of the securities of the Issuer (File No. 333-287281) (the "Registration Statement") under the heading "Description of Securities-Share Rights," each right will automatically convert into one-tenth (1/10) of one Class A ordinary share upon consummation of the Issuer's initial business combination, subject to certain adjustments described therein. No fractional Class A ordinary shares will be issued upon conversion of such rights.

Footnote F4

Represents 6,769,913 Class B ordinary shares held by the Sponsor acquired pursuant to a subscription agreement by and between the Issuer and the Sponsor. As described in the Registration Statement under the heading "Description of Securities--Founder Shares," the Class B ordinary shares will automatically convert into shares of Class A ordinary shares at the time of the Issuer's initial business combination, or at any time prior to the Issuer's initial business combination, at the option of the holder, on a one-for-one basis, subject to certain adjustments.
