### Footnotes:

(1) As described in the issuer's registration statement on Form S-1 (File No. 333-293233) under the heading "Description of Securities-Founder Shares", the Class B ordinary shares will automatically convert into Class A ordinary shares, par value $0.0001 per share, of the issuer at the time of the issuer's initial business combination, or earlier at the option of the holder, on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like, and certain anti-dilution rights and have no expiration date.

(2) These shares represent Class B ordinary shares held by Kensington Capital VI LLC (the "Sponsor") that were acquired pursuant to a subscription agreement by and between the Sponsor and the issuer.  The Class B ordinary shares owned by the Sponsor include up to 1,285,714 shares that are subject to forfeiture to the extent the underwriters of the initial public offering do not exercise in full their over-allotment option as described in the foregoing registration statement of the issuer.

(3) Justin Mirro, the issuer's Chairman and Chief Executive Officer, has voting and investment discretion with respect to the securities held by the reporting person and may be deemed to have shared beneficial ownership of the securities held directly by the reporting person.  Mr. Mirro disclaims any beneficial ownership of the reported shares, other than to the extent of any pecuniary interest he may have therein, directly or indirectly.
