The information set forth in Items 2, 3 and 6 of this Schedule 13D is hereby incorporated by reference into this Item 4.

The Reporting Persons acquired the securities reported herein for investment purposes and intend to review their investments in the Issuer on a continuing basis. Subject to the agreements described herein and various factors, including but not limited to the Issuer's financial position and strategic direction, price levels of the Common Stock, conditions in the securities markets, various laws and regulations applicable to the Issuer and companies in its industry and the Reporting Persons' ownership in the Issuer, and general economic and industry conditions, the Reporting Persons may in the future take actions with respect to their investment in the Issuer as they deem appropriate, including changing their current intentions, with respect to any or all matters required to be disclosed in this Schedule 13D. The Reporting Persons may, from time to time, acquire, or cause affiliates to acquire, additional shares of Common Stock or other securities of the Issuer (including any combination or derivative thereof), dispose, or cause affiliates to dispose, of some or all of their Common Stock or other securities of the Issuer or continue to hold, or cause affiliates to hold, Common Stock or other securities of the Issuer (or any combination or derivative thereof).

In addition, the Reporting Persons have engaged and intend to continue to engage in discussions with management or the board of directors of the Issuer about its business, operations, strategy, plans and prospects, from time to time.

Notwithstanding the foregoing, the Reporting Persons may determine to change their respective intentions with respect to the Issuer at any time in the future and may, for example, elect (i) to acquire additional securities of the Issuer in open market or privately negotiated transactions or (ii) to dispose of all or a portion of the Reporting Persons' holdings of securities of the Issuer.

Registration Rights Agreement

On January 30, 2026, in connection with the closing of the Transaction, the Issuer and BPPUS entered into a Registration Rights Agreement (the "Registration Rights Agreement"). Pursuant to the Registration Rights Agreement, the Issuer has agreed to, among other things, (i) provide BPPUS with certain Form S-3 demand and piggyback registration rights for the 5,315,390 shares of Common Stock issued to BPPUS pursuant to the BPPUS Purchase Agreement, subject to customary cutbacks, lock-up periods, blackout periods and other limitations, (ii) pay certain registration expenses and (iii) provide BPPUS with customary indemnification rights.

Stockholders' Agreement

In connection with the closing of the Issuer's initial public offering, on September 27, 2024, the Issuer and BNAC entered into a Stockholders' Agreement (the "Stockholders' Agreement"). Pursuant to the Stockholders' Agreement, for so long as BNAC and BPCL beneficially own 10% or more of the Issuer's voting stock, BNAC will be entitled to designate for nomination to the Issuer's board of directors a number of individuals (collectively, the "BNAC Designees") approximately proportionate to such beneficial ownership, provided that (i) from and after September 27, 2025 until the first date on which BNAC and BPCL beneficially own 50% or less of our voting stock, at least four board seats will not be BNAC Designees, and (iii) from and after the first date on which BNAC and BPCL beneficially own 50% or less of our voting stock, a number of board seats equal to the minimum number of directors that would constitute a majority of the total number of directors comprising the Issuer's board of directors will not be BNAC Designees. Under the Stockholders' Agreement, the Issuer has agreed to use its best efforts to cause the election of the BNAC Designees, including nominating such individuals to be elected as a director, recommending their election and soliciting proxies or consents in favor of their election. The Stockholders' Agreement also provides that the Issuer and BNAC shall, to the extent permitted by law, take actions to cause the Issuer's Chief Executive Officer to be included on the Issuer's board of directors. In addition, for so long as BNAC and its affiliates beneficially own shares of the Issuer's voting stock representing at least 25% of the Issuer's total voting power, BNAC will have the right to designate the chairman of the Issuer's board of directors from among the BNAC Designees. The BNAC Designees as of the date of this Schedule 13D include Messrs. Kalnin, C. Vongkusolkit, Sirisaengtaksin, Dayananda, Limpaphayom, Mekavichai and S. Vongkusolkit, as well as Ms. Chaimongkol, and BNAC designated C. Vongkusolkit as the chairman of the Issuer's board of directors. As directors, they may have influence over the corporate activities of the Issuer, including activities which may relate to the transactions described in clauses (a) through (j) of Item 4 of Schedule 13D.

The Stockholders' Agreement also provides BNAC with certain information rights for so long as it continues to own shares of the Issuer's voting stock representing at least 25% of the Issuer's voting power. Further, the Issuer may not amend its Second Amended and Restated Certificate of Incorporation or its Bylaws in a manner inconsistent with the rights granted to BNAC pursuant to the Stockholders' Agreement without BNAC's consent. The Stockholders' Agreement will terminate on the earlier to occur of (i) such time as BNAC is no longer entitled to designate a director pursuant to our Stockholders' Agreement (except that the registration rights discussed below will survive and continue until BNAC and its affiliates no longer hold any shares of our common stock constituting registrable securities (as defined in our Stockholders' Agreement)) and (ii) the delivery of written notice by BNAC to us requesting termination of our Stockholders' Agreement.

The Stockholders' Agreement also provides BNAC and its affiliates with the right, in certain circumstances, to require the Issuer to register its shares of Common stock constituting registrable securities under the Securities Act for sale into the public markets and with certain piggyback rights. The Stockholders' Agreement also provides that the Issuer will pay certain expenses of BNAC and its affiliates relating to such registrations and indemnify them against certain liabilities that may arise under the Securities Act. On October 1, 2025, the Issuer filed a Registration Statement on Form S-3 (Registration No. 333-290676) (as amended on November 25, 2025, the "Resale Registration Statement") to register the offer and sale of 63,877,614 shares of Common Stock owned by BNAC in accordance with the registration rights granted under the Stockholders' Agreement. As of the date of this Schedule 13D, no shares of Common Stock have been sold by BNAC pursuant to the Resale Registration Statement.

The descriptions of the BPPUS Purchase Agreement, Registration Rights Agreement and Stockholders Agreement contained in this Item 6 are not intended to be complete and are qualified in their entirety by reference to such agreements, each of which is filed as an exhibit hereto or incorporated by reference herein.
