Based on the closing price of the Company’s Class A Common Stock (as reported on the Nasdaq Global Select Market) of $21.49 per share on June 21, 2022, the last trading day prior to announcement of the Merger Agreement, the transaction represents aggregate stock consideration of approximately $93 million and a consideration per share of Class A Common Stock of USWS, par value $0.0001 per share (the “USWS Common Stock”) of $1.21. After giving effect to the conversions of certain securities of USWS, as described in the USWS Merger 8-K, the total stock consideration payable to USWS stockholders and holders of USWS equity awards, based on the Company’s Class A Common Stock June 21, 2022 closing price, would be approximately $270 million.

Dan Wilks and Farris Wilks, together with certain of their affiliates, (collectively, the “Wilks Parties”) collectively hold a controlling interest in the Company. Certain Wilks Parties also own certain securities of USWS. Upon the consummation of the Merger, the Wilks Parties will receive an aggregate of 4,112,407 shares of the Company’s Class A Common Stock as merger consideration (assuming, solely for the purpose of this calculation, a hypothetical closing date of October 31, 2022), which, based on the Company’s Class A Common Stock June 21, 2022 closing price, would be approximately $88.4 million.

The representations and warranties of the respective parties to the Merger Agreement will not survive the closing of the Merger. The Merger Agreement includes customary covenants of the parties, including, among others, covenants (a) for the Parties to conduct their respective businesses in the ordinary course during the interim period between the date of the execution of the Merger Agreement and the consummation of the Merger, (b) that the Parties not engage in certain kinds of transactions during the interim period between the date of the execution of the Merger Agreement and the consummation of the Merger, (c) that the Company use commercially reasonable efforts to obtain and consummate a financing to fund the repayment in connection with the closing of the Merger of certain indebtedness of USWS and its subsidiaries as promptly as reasonably possible following the date of the Merger Agreement, (d) that USWS reasonably cooperate with such financing efforts and (e) providing for the Company and USWS to
