4.       We note descriptions of the Transfer Agreement among Cognos, certain
shareholders and
         Helena, and the Amended and Restated Sponsor Forfeiture Agreement

         the Sponsor, Cognos and certain Cognos shareholders. Please file the

Risk Factors
Risks Related to Compliance with Law, Government Regulation and Litigation
If we were deemed to be an investment company under the 1940 Act, as a result
of our
ownership of Cognos..., page 48

5.       We note your statement that "as of September 30, 2023, in order to
mitigate the risk that
         the Company could be deemed to be operating as an unregistered
investment company
         under the 1940 Act, the Company instructed Continental to liquidate
the Company   s
         investments in money market funds invested primarily in U.S. Treasury
securities and
         thereafter to hold all funds in the Trust Account in cash or in U.S.
Treasury securities until
         the earlier of the consummation of the initial business combination or
the Company   s
         liquidation." Because it appears that assets in your trust account may
be held in U.S.
         Government securities, please disclose the risk that you could be
considered to be
         operating as an unregistered investment company. Please disclose that
if you are found to
         be operating as an unregistered investment company, you may be
required to change your
         operations, wind down your operations, or register as an investment
company under the
         Investment Company Act. Please also include disclosure with respect to
the consequences
         to investors if you are required to wind down your operations as a
result of this status,
         such as the losses of the investment opportunity in a target company,
any price
         appreciation in the combined company, and any warrants, which would
expire worthless.
Executive Compensation of Cognos, page 229

6.       Please include executive compensation disclosure for Cognos' executive
officers for the
         fiscal year ended December 31, 2023. For guidance, please refer to
Items 18(a)(7)(ii) and
         18(b) of Part I of Form S-4, Item 402 of Regulation S- K and Question
117.05 of the
         Compliance & Disclosure Interpretations for Regulation S-K.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.
