Item 4. Ownership

   Provide the following information regarding the aggregate number and percentage of the class of securities of the issuer identified in Item 1.

(a) Amount Beneficially Owned

   As of the close of business on December 7, 2021, the reporting persons beneficially owned an aggregate of 1,578,029 of the Issuer’s Class A Ordinary Shares or 5.1% of the Issuer’s Class A Ordinary Shares outstanding as a result of holding 1,481,570 of the Issuer’s Class A Ordinary Shares and 96,459 of the Issuer’s units. Each unit consists of one Class A Ordinary Share of the Issuer and one-fifth of one warrant. Each whole warrant entitles the holder to purchase one Class A Ordinary Share of the Issuer. The Issuer’s warrants will become exercisable 30 days after the completion of the Issuer’s initial business combination.

   Thereafter, as of the close of business on December 9, 2021:

   i) Integrated Core Strategies (US) LLC, a Delaware limited liability company ("Integrated Core Strategies"), beneficially owned 266,000 of the Issuer’s Class A Ordinary Shares as a result of holding 205,000 of the Issuer’s Class A Ordinary Shares and 61,000 of the Issuer’s units;

   ii) Riverview Group LLC, a Delaware limited liability company ("Riverview Group"), beneficially owned 332,617 of the Issuer’s Class A Ordinary Shares;

   iii) ICS Opportunities II LLC, a Cayman Islands limited liability company ("ICS Opportunities II"), beneficially owned 491,589 of the Issuer’s Class A Ordinary Shares as a result of holding 456,130 of the Issuer’s Class A Ordinary Shares and 35,459 of the Issuer’s units; and

   iv) ICS Opportunities, Ltd., an exempted company organized under the laws of the Cayman Islands ("ICS Opportunities"), beneficially owned 284,500 of the Issuer’s Class A Ordinary Shares, which together with the Issuer’s Class A Ordinary Shares beneficially owned by Integrated Core Strategies, Riverview Group and ICS Opportunities II represented 1,374,706 of the Issuer’s Class A Ordinary Shares or 4.4% of the Issuer’s Class A Ordinary Shares outstanding.

   Millennium International Management LP, a Delaware limited partnership ("Millennium International Management"), is the investment manager to ICS Opportunities II and ICS Opportunities and may be deemed to have shared voting control and investment discretion over securities owned by ICS Opportunities II and ICS Opportunities.

   Millennium Management LLC, a Delaware limited liability company ("Millennium Management"), is the general partner of the managing member of Integrated Core Strategies and Riverview Group and may be deemed to have shared voting control and investment discretion over securities owned by Integrated Core Strategies and Riverview Group. Millennium Management is also the general partner of the 100% owner of ICS Opportunities II and ICS Opportunities and may also be deemed to have shared voting control and investment discretion over securities owned by ICS Opportunities II and ICS Opportunities.

   Millennium Group Management LLC, a Delaware limited liability company ("Millennium Group Management"), is the managing member of Millennium Management and may also be deemed to have shared voting control and investment discretion over securities owned by Integrated Core Strategies and Riverview Group. Millennium Group Management is also the general partner of Millennium International Management and may also be deemed to have shared voting control and investment discretion over securities owned by ICS Opportunities II and ICS Opportunities.

   The managing member of Millennium Group Management is a trust of which Israel A. Englander, a United States citizen ("Mr. Englander"), currently serves as the sole voting trustee. Therefore, Mr. Englander may also be deemed to have shared voting control and investment discretion over securities owned by Integrated Core Strategies, Riverview Group, ICS Opportunities II and ICS Opportunities.

   The foregoing should not be construed in and of itself as an admission by Millennium International Management, Millennium Management, Millennium Group Management or Mr. Englander as to beneficial ownership of the securities owned by Integrated Core Strategies, Riverview Group, ICS Opportunities II or ICS Opportunities, as the case may be.

(b) Percent of Class:   

   As of the close of business on December 9, 2021, Millennium Management, Millennium Group Management and Mr. Englander may be deemed to have beneficially owned 1,374,706 of the Issuer’s Class A Ordinary Shares or 4.4% of the Issuer’s Class A Ordinary Shares outstanding (see Item 4(a) above), which percentage was calculated based on 31,116,305 of the Issuer’s Class A Ordinary Shares outstanding as of November 5, 2021, as reported in the Issuer’s Form 10-Q/A filed on November 26, 2021.
