Certificate of Correction to Certificate of Formation

On August 12, 2026, the Company filed a Certificate of Correction (the “Certificate of Correction”) to its Certificate of Formation (as previously filed, amended, corrected, supplemented or restated, the “Certificate of Formation”) with the Secretary of State of the State of Texas. Article IV (Capital Stock) of the Certificate of Formation inadvertently stated that the aggregate number of shares of capital stock authorized under the Certificate of Formation was 640,000,000, whereas the class-level authorizations listed in the Certificate of Formation equaled 740,000,000 shares, comprised of 310,000,000 shares of Class A common stock, 330,000,000 shares of Class B common stock and 100,000,000 shares of preferred stock. The Certificate of Correction corrects this scrivener’s error so that the stated aggregate number of authorized shares equals 740,000,000, conforming the aggregate figure to the total of the class-level authorizations. The Certificate of Correction did not change any class-level authorization, the par value of any class or series, or any other provision of the Certificate of Formation.

In accordance with the Texas Business Organizations Code, upon the filing of the Certificate of Correction by the Secretary of State of the State of Texas, the Certificate of Formation is considered to have been corrected as of the date it was originally filed, except as to persons who are adversely affected by the correction, as to whom the Certificate of Formation is considered to have been corrected as of the date the Certificate of Correction was filed. The foregoing description of the Certificate of Correction does not purport to be complete and is qualified in its entirety by reference to the full text of the Certificate of Correction, a copy of which is filed as Exhibit 3.3 to this Report and incorporated herein by reference.
