           Amendment No. 2 to Draft Registration Statement on Form F-1
           Submitted July 22, 2025
           CIK No. 0002046954
Dear Wong Kok Seng:

     We have reviewed your amended draft registration statement and have the
following
comments.

       Please respond to this letter by providing the requested information and
either
submitting an amended draft registration statement or publicly filing your
registration
statement on EDGAR. If you do not believe a comment applies to your facts and
circumstances or do not believe an amendment is appropriate, please tell us why
in your
response.

       After reviewing the information you provide in response to this letter
and your
amended draft registration statement or filed registration statement, we may
have additional
comments. Unless we note otherwise, any references to prior comments are to
comments in
our June 18, 2025 letter.

Amendment No. 2 to Draft Registration Statement on Form F-1
Prospectus Summary, page 1

1.     We note your response to prior comment 3. Please update your
organizational chart on
       page 7, and elsewhere as necessary, to include the voting control of
those parties prior

2.     We note in the disclosure regarding UMSB on page 36 you refer to the
"Concert
       Parties" however, in your response to prior comment 4 you did not refer
to an acting-
       in-concert agreement governing the control of UMSB. Please clarify your
disclosure
       and advise us. If an acting-in-concert agreement governing the control
of UMSB
       exists, disclose the details of this agreement including the date, the
parties involved,
       and the identity of the controlling person(s) on pages 36 and F-9. You
should also file
       this agreement as an exhibit.
3.     We note after Mr. Halim transferred his 20% equity interest in UMSB on
December 6,
       2023, he held no equity in UMSB. Clarify in your disclosure your basis
for
       consolidating this entity with the other entities for which Mr. Halim
holds a
       controlling equity interest and advise us in detail.
4.     Disclose on pages 37 and F-10 why the Group is considered to exercise
control over
       PT Ultratrex Indonesia and not Mr. Halim, and advise us. In light of his
98% equity
       interest it appears he controls.
5.     Disclose on pages 37 and F-10 why the Group is considered to have
exercised control
       over Ultratrex Co. Ltd and not Mr. Halim, and advise us. In light of his
90% equity
       interest in Ultrator Co., Ltd, it appears he controlled it prior to the
November 29,
       2024 acquisition by Ultratrex Singapore.

prior to
       the July 3, 2024 date of incorporation. Similarly revise the disclosure
