PwC due diligence
         summary that no relevant undisclosed financial liabilities, including
tax or labor liabilities
         were discovered in the financial due diligence. Please revise to
specify whether such
         conclusions were those of HPX or of the professional advisor. If the
latter, please provide
         additional analysis as to why none of these summaries is    a report,
opinion, or appraisal
         materially relating to the transaction    pursuant to Item 4(b) of
Form F-4. In this regard,
         we note that Item 4(b) of Form F-4 requires that the information
required by Item 1015(b)
         of Regulation M-A be provided with respect to a report, opinion, or
appraisal that is (i)
         materially related to the transaction and (ii) referred to in the
prospectus, and is not limited
         to the fairness or amount of consideration to be paid in connection
with the Business
         Combination.

         If the conclusions reached by the due diligence process described in
the filing were those
         of the professional advisor, also provide additional analysis as to
why a consent is not
         required from each such professional advisor. Refer to Rule 436 and
Securities Act
         Section 7.

7.       We note your disclosure in response to prior comment 16 that Skadden,
Arps, Slate,
         Meagher & Flom LLP has delivered an opinion that the First Merger
"should" qualify as
         an F Reorganization. If the opinion is subject to uncertainty, please
obtain a revised
         opinion that explains why counsel cannot give a    will    opinion
and describes the degree
         of uncertainty in the opinion. In addition, please provide risk factor
disclosure setting
         forth the risks of uncertain tax treatment to investors, if
applicable. For guidance, refer to
         Section III.C.4 of Staff Legal Bulletin 19. We note also that the tax
opinion filed as
         Exhibit 8.1 states that counsel expresses no opinion on the potential
United States federal
         income tax consequences of the First Merger pursuant to Section 367 of
the Code. Please
         ensure that you have disclosed the material tax consequences of the
Business
         Combination, and ensure that the tax opinion addresses and expresses a
conclusion for
         each material tax consequence. In that regard, please tell us the
basis for excluding from
         the opinion the potential United States federal income tax
consequences of the First
         Merger pursuant to Section 367 of the Code. To the extent material,
please also disclose
         any tax consequences pursuant to Section 367 of the Code.

8.       We note your disclosure of inflationary costs pressure on your cost of
services rendered,
         and the decrease in gross margin during your fiscal year ended
December 31, 2020 and
         the six-months ended June 30, 2022 primarily due to the increase in
cost of services
         rendered as a percentage of net revenue as a result of increased costs
related to third-party
         providers, fuel and maintenance, caused by inflationary cost pressure,
supply chains
         disruptions, and increases in oil prices in the period, as well as
decreased economies of
         scale. Please update your disclosure to identify actions planned or
taken, if any, to
         mitigate inflationary pressures and supply chain disruptions.

comment 26. However,
         we also noted from page F-93 that you continue to label $70,517 as

it is appropriate.
13.      We note you made 15 acquisitions in 2021. However, your disclosure on
page F-94
         indicates only one acquired company contributed to the net revenue and
profit. Please
         explain and revise your disclosures as applicable.
