Class A ordinary shares, $0.00001 par value per share

**(b) Name of Issuer:**
Skyline Builders Group Holding Limited

**(c) Address of Issuer's Principal Executive Offices:**
Office A, 15/F, Tower A, Capital Tower, No. 38 Wai Yip Street, Kowloon Bay, K3, 00000

This statement on Schedule 13D (this "Schedule 13D") relates to the Class A ordinary shares, par value $0.00001 per share (the "Class A Shares"), of Skyline Builders Group Holding Limited, a Cayman Islands exempted company (the "Issuer"). The principal executive offices of the Issuer are located at Office A, 15/F, Tower A, Capital Tower, No. 38 Wai Yip Street, Kowloon Bay, Hong Kong.

**Item 4. Purpose of Transaction**

On August 29, 2025, Quantum Leap Energy LLC ("QLE"), a wholly owned subsidiary of ASP Isotopes Inc., became a controlling shareholder of Skyline Builders Group Holding Limited, a company incorporated under the laws of the Cayman Islands ("SKBL" or the "Issuer") with its Class A Ordinary Shares listed on The Nasdaq Stock Market LLC under the symbol "SKBL". QLE intends to use SKBL to pursue opportunities to acquire assets in the critical materials supply chain that QLE believes will help the United States and QLE secure important feedstocks that are vital to the security of the United States and long-term growth of QLE.
 
 SKBL Share Capital Structure.  SKBL has a dual class ordinary share structure. SKBL's Ordinary Shares are divided into Class A Ordinary Shares ("Class A Ordinary Shares") and Class B Ordinary Shares ("Class B Ordinary Shares"). Each Class A Ordinary Share entitles the holder thereof to one (1) vote on all matters subject to vote at general meetings of SKBL, and each Class B Ordinary Share entitles the holder thereof to twenty (20) votes on all matters subject to vote at general meetings of SKBL.  In no event shall Class A Ordinary Shares be convertible into Class B Ordinary Shares. In no event shall Class B Ordinary Shares be convertible into Class A Ordinary Shares.
  
 QLE's Purchase of Controlling Interest in SKBL. On August 27, 2025, Supreme Development (BVI) Holdings Limited ("SD"), SKBL's previous controlling shareholder and a company beneficially owned by Mr. Ngo Chiu Lam, SKBL's Chief Executive Officer, entered into a definitive securities purchase agreement with QLE pursuant to which SD transferred and sold to QLE all 1,995,000 issued and outstanding Class B Ordinary Shares ("Class B Share Transfer"), for the aggregate purchase price of $1,000,000. As a holder of Class B Ordinary Shares, QLE is entitled to cast 20 votes per share and to vote together with holders of Class A Ordinary Shares on all matters submitted to the vote of shareholders of SKBL.
   
 SKBL Private Placement.  On August 29, 2025, SKBL closed a private placement (the "Private Placement") pursuant to which SKBL issued and sold (i) 1,359,314 Class A Ordinary Shares, (ii) prefunded warrants to purchase 22,990,000 Class A Ordinary Shares, at an exercise price of $0.0001 per share ("Prefunded Warrant"), (iii) Class A Ordinary Share Purchase Warrant As to purchase up to 24,349,314 Class A Ordinary Shares, at an exercise price of $0.60 per share ("A Warrant"), (iv) Class A Ordinary Share Purchase Warrant Bs to purchase up to 24,349,314 Class A Ordinary Shares, at an exercise price of $0.65 per share ("B Warrant" and together with Prefunded Warrant and A Warrant, "Warrants"), and (v) placement agent warrants to purchase 1,947,945 Class A Ordinary Shares issued to the placement agents of the Private Placement as compensation.  SKBL received aggregate gross proceeds of $17,775,000 from the Private Placement, before deducting fees and offering expenses.
   
 In the Private Placement, QLE purchased: (i) 454,794 Class A Ordinary Shares, (ii) a Prefunded Warrant to purchase 1,600,000 Class A Ordinary Shares, (iii) a A Warrant to purchase 2,054,794 Class A Ordinary Shares, and (iv) a B Warrant to purchase 2,054,794 Class A Ordinary Shares, for the aggregate purchase price of $1,500,000, pursuant to a Securities Purchase Agreement with SKBL, dated as of August 27, 2025 (the "Purchase Agreement").  Each Warrant is immediately exercisable and entitles the holder to acquire Class A Ordinary Shares for a period of five years following August 29, 2025.
  
 SKBL Share Retirement. Approximately $7,000,000 of the proceeds from the Private Placement was used to retire 18,500,000 Class A Ordinary Shares owned by SD, SKBL's previous controlling shareholder (the "Share Retirement").
  
 QLE as Controlling Shareholder.  After giving effect to the Class B Share Transfer, the Private Placement and the Share Retirement, QLE became the holder of 79.14% of the aggregate voting power represented by all outstanding Class A Ordinary Shares and Class B Ordinary Shares, and thereby gaining control over SKBL.
  
 Director Appointments.  Effective on September 18, 2025, the Board of Directors (the "Board") of the Issuer approved the appointments of Dr. Ryno Pretorius ("Dr. Pretorius") and Mr. Jacob Rowe ("Mr. Rowe") as independent directors of the Issuer, to fill the vacancies resulting from the resignations of former directors Ms. Li and Mr. Cha. Dr. Pretorius is the Chief Executive Officer of Quantum Leap Energy LLC and Mr. Rowe is Vice President of Business Development and Investor Relations at ASP Isotopes Inc.
 
 Plans or Proposals.  The Reporting Persons do not have any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons have acquired the shares reported herein for investment purposes. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer's financial position and investment strategy, the price levels of the Issuer's ordinary shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons and their representatives may in the future take such actions with respect to his investment in the Issuer as he deems appropriate. Among other things, the Reporting Persons may introduce the Issuer to potential candidates for a business combination, or propose one or more business combinations with potential candidates, which may include candidates that are affiliates of the Reporting Persons or in which the Reporting Persons otherwise have an equity or other interest. In addition, representatives of the Reporting Persons will be involved in negotiations in connection with any prospective business combination of the Issuer, the decisions of the board of directors related to any such business combination, and any matters to be presented to the Issuer's shareholders in connection therewith. The Reporting Persons are expected to be involved in reviewing possible transactions involving the Issuer and identifying candidates to serve on the board of directors. As such, the Reporting Persons may be involved in transactions of the sort described in clauses (a) through (j) of Item 4 of Schedule 13D. The Reporting Persons may purchase ordinary shares of the Issuer and/or rights in privately negotiated transactions or in the open market either prior to, in connection with or following the completion of the Issuer's initial business combination. The purpose of any such purchases of shares could be to satisfy a closing condition in an agreement with a target that requires the Issuer to have a minimum net worth or a certain amount of cash at the closing of the Issuer's initial business combination, where it appears that such requirement would otherwise not be met. The purpose of any such purchases of rights could be to reduce the number overhang of the rights on the outstanding share capital. Any such purchases of the Issuer's securities may result in the completion of an initial business combination that may not otherwise have been possible.

**Item 5. Interest in Securities of the Issuer**

**(a)**
The information set forth in the facing pages of this Schedule 13D with respect to the beneficial ownership of the Reporting Persons is incorporated by reference into this Item 5.
