(b) The Registrant’s Current Report on Form 8-K filed with the SEC on January 6, 2026; and

(c) The description of the Registrant’s Class A common stock contained in the Registrant’s registration statement on Form 8-A filed with the SEC on December 8, 2025 (File No. 001-42997), to register such securities under the Securities Exchange Act of 1934 (the “Exchange Act”), including any amendment or report filed for the purpose of updating such description.

In addition, all documents subsequently filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934 (the “Exchange Act”), prior to the filing of a post-effective amendment to this Registration Statement which indicates that all securities offered have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference in this Registration Statement and to be part hereof from the date of filing of such documents with the SEC.

Any statement contained in a document incorporated or deemed to be incorporated by reference in this Registration Statement shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained in this Registration Statement, or in any other subsequently filed document that also is or is deemed to be incorporated by reference in this Registration Statement, modifies or supersedes such prior statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

Under no circumstances will any information furnished under Items 2.02 or 7.01 of Current Report on Form 8-K be deemed incorporated herein by reference unless such Form 8-K expressly provides to the contrary.

Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

The Registrant’s Amended and Restated Certificate of Formation and Amended and Restated Bylaws contain provisions that limit the liability of the Registrant’s directors and officers for monetary damages to the fullest extent permitted by Texas law, as it presently exists or may hereafter be amended from time to time. Consequently, the Registrant’s directors and officers will not be personally liable to the Registrant or the Registrant’s shareholders for monetary damages for any breach of fiduciary duties as directors and officers, except liability for:

These limitations of liability do not apply to liabilities arising under federal securities laws and do not affect the availability of equitable remedies such as injunctive relief or rescission.

The Registrant’s Amended and Restated Certificate of Formation and Amended and Restated Bylaws provide that the Registrant is required to indemnify the Registrant’s directors and officers, in each case to the fullest extent permitted by Texas law. Any repeal of or modification to the Registrant’s Amended and Restated Certificate of Formation and Amended and Restated Bylaws may not adversely affect any right or protection of a director or officer for or with respect to any acts or omissions of that director or officer occurring prior to that amendment or repeal. The Registrant’s Amended and Restated Bylaws also provide that the Registrant will advance expenses incurred by a director or officer in advance of the final disposition of any action or proceeding, and permit the Registrant to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in that capacity regardless of whether the Registrant would otherwise be permitted to indemnify him or her under the provisions of Texas law. The Registrant’s directors and officers will be covered by insurance indemnifying them against certain liabilities which might be incurred by them in their capacities as such, including certain liabilities under the Securities Act. The Registrant has entered and expects to continue to enter into agreements to indemnify the Registrant’s directors and executive officers. With certain exceptions, these agreements provide for indemnification for (i) any and all liabilities and reasonable expenses, including damages, judgments, fines, penalties, ERISA excise taxes and amounts paid in settlement of any claim with the Registrant’s approval and reasonable counsel fees and disbursements and (ii) any liabilities incurred arising out of, relating to or resulting from the indemnitee’s acting on behalf of the Registrant in connection with the operation, administration or maintenance of the employee benefit plan or any related trust or funding mechanism. The Registrant believes that these bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and executive officers.

The limitation of liability and indemnification provisions in the Registrant’s Amended and Restated Certificate of Formation and Amended and Restated Bylaws may discourage shareholders from bringing a lawsuit against the Registrant’s directors and officers for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against the Registrant’s directors and officers, even though an action, if successful, might benefit the Registrant and other shareholders. Further, a shareholder’s investment may be adversely affected to the extent that the Registrant pays the costs of settlement and damage awards against directors and officers as required by these indemnification provisions. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, executive officers or persons controlling the Registrant, the Registrant has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 7. Exemption from Registration Claimed.

Not applicable.

Item 8. Exhibits.

The following exhibits are filed herewith or incorporated herein by reference.

Item 9. Undertakings.

A. The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

provided, however, that paragraphs (A)(1)(i) and (A)(1)(ii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

B. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

C. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
