Item 5(a)-(b) of the Schedule 13D are each hereby amended and restated in their entirety as follows and as set forth in subsection 5(b): The responses of the Reporting Persons set forth in rows (11) and (13) of the cover pages of this Amendment No. 1 are incorporated by reference into this Item 5(a). Beckham Aggregator, L.P. directly holds the securities reported herein and, in its capacity as the general partner of Beckham Aggregator, L.P., BT Parent GP, LLC may be deemed to beneficially own the reported securities. The reported number and percentage do not include shares of Class A Common Stock to be received in settlement of restricted stock units upon Zach F. Sadek's retirement from service on the Board of Directors of the Issuer (the "Board). Prior to his retirement, any such restricted stock units will be held by Mr. Sadek for the benefit of PCP Managers II, L.P. (the "Manager"), an affiliate of the Reporting Persons. Pursuant to an agreement between Mr. Sadek and the Manager, Mr. Sadek is obligated to transfer to the Manager any shares received upon settlement of such restricted stock units. The reported percentage of shares of Class A Common Stock is based upon 89,672,978 shares of Class A Common Stock outstanding and 5,285,883 shares of Class A Common Stock issuable upon conversion of an equivalent number of units in a subsidiary of the Issuer (and cancellation of shares of Class V common stock) each as of April 29, 2026, as disclosed in the Issuer's Quarterly Report on Form 10-Q, filed by the Issuer with the SEC on May 4, 2026. In accordance with the SEC's rules for calculating "beneficial ownership," which requires the Reporting Persons to disregard shares of Class A Common Stock issuable upon the conversion of units and shares of Class V common stock not held by the Reporting Persons, the Reporting Persons would be deemed to beneficially own approximately 9.93% of the outstanding Class A Common Stock. Notwithstanding the foregoing, because a unit (and a corresponding portion of a share of Class V common stock) are economically equivalent to a share of Class A Common Stock and further, the Class V common stock votes together with the Class A Common Stock, the reported 9.38% better reflects the Reporting Person's actual economic and voting interest in the Issuer. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by any of the Reporting Persons that it is the beneficial owner of any of the shares of Class A Common Stock reported herein for the purposes of Section 13(d) of the Act, or for any other purpose, and such beneficial ownership is expressly disclaimed by each Reporting Person, other than Beckham Aggregator, L.P. with respect to securities reported as directly held by Beckham Aggregator, L.P.

The responses of the Reporting Persons set forth in rows (7) through (10) of the cover pages of this Amendment No. 1 and the information set forth in Item 5(a) hereof are incorporated by reference into this Item 5(b).

The Reporting Persons have not effected any transactions in the Class A Common Stock during the past 60 days.

Item 6 of the Schedule 13D is hereby amended and supplemented to add the following: On July 13, 2026, the Manager entered into a cooperation agreement (the "Cooperation Agreement") with the Issuer, pursuant to which the Board (i) increased the size of the Board from six (6) to seven (7) members and (ii) appointed Mr. Sadek to the Board to fill the newly created vacancy resulting from the increase in the size of the Board, effective July 13, 2026, with an initial term expiring at the Issuer's 2027 annual meeting of stockholders (the "2027 Annual Meeting"). The Issuer further agreed to nominate Mr. Sadek as a candidate for election to the Board at the 2027 Annual Meeting, provided that such obligation will terminate automatically upon Mr. Sadek's departure from the Board. The Cooperation Agreement also contains certain customary standstill restrictions and confidentiality obligations, which will remain in effect until the earlier of (i) thirty (30) calendar days after the date of Mr. Sadek's departure from the Board and (ii) the first day following the conclusion of the 2027 Annual Meeting, subject to certain exceptions. The foregoing description does not purport to be complete and is qualified in its entirety by reference to the full text of the Cooperation Agreement, which is included as Exhibit 99.C and is incorporated by reference herein.

Exhibit 99.C: Cooperation Agreement, dated July 13, 2026 (incorporated by reference to Exhibit 10.1 of the Issuer's Current Report on Form 8-K filed with the Securities and Exchange Commission on July 14, 2026).
