### Footnotes:

(1) As described in the registrant's Registration Statement on Form S-1 (File No. 333-291924) under the heading "Description of Securities-Founder Shares," the Class B ordinary shares will automatically convert into Class A ordinary shares at the time of the registrant's initial business combination, or at any time prior thereto at the option of the holder thereof, on a one-for-one basis, subject to certain adjustments described therein, and have no expiration date.

(2) These Class B ordinary shares include an aggregate of 1,137,858 Class B ordinary shares that are subject to forfeiture to the extent that the underwriters do not exercise their over-allotment option in connection with the registrant's initial public offering in full.

(3) HC VIII Sponsor LLC ("Sponsor") is the record holder of the securities reported herein. Hennessy Capital Group LLC is the sole manager of Sponsor. Daniel J. Hennessy, the registrant's Chairman and Chief Executive Officer, and Thomas D. Hennessy, the registrant's President and a director, are the managing members of Hennessy Capital Group LLC. Consequently, each of Mr. Daniel Hennessy and Mr. Thomas Hennessy may be deemed the beneficial owner of securities held by Sponsor and have shared voting and dispositive control over such securities. Mr. Thomas Hennessy disclaims beneficial ownership over any securities owned by Sponsor in which he does not have any pecuniary interest.
