 NOTES TO PARENT COMPANY FINANCIAL STATEMENTS

 1. ORGANIZATION AND DESCRIPTION OF BUSINESS

 ProFrac Holding Corp. ("ProFrac Corp.") is a holding company with substantially all of its assets and operations held by ProFrac Holdings, LLC ("ProFrac LLC"), which is a vertically integrated and innovation-driven energy services company providing hydraulic fracturing, completion services and other complementary products and services to leading upstream oil and gas companies engaged in the exploration and production of North American unconventional oil and natural gas resources.
 Mr. Dan Wilks and Mr. Farris Wilks are brothers and are the founders and principal stockholders of the Company. Their sons, Mr. Matthew D. Wilks and Mr. Johnathan Ladd Wilks, are the Company's Executive Chairman and Chief Executive Officer, respectively. In the normal course of business, we enter into transactions with related parties where Mr. Dan Wilks and Mr. Farris Wilks and entities owned by or affiliated with them (collectively, the "Wilks Parties") hold a controlling financial interest. See "Notes to the Consolidated Financial Statements—Note 16 – Related Party Transactions" included in the Company's Annual Report on Form 10-K for further discussion of these related party transactions.
 Basis of Presentation
 These condensed parent company financial statements reflect the unconsolidated financial position of ProFrac Corp. as the parent company to ProFrac LLC. Given that certain of our subsidiaries are restricted in their ability to transfer funds to us as a result of their debt covenants, we have prepared these condensed parent company financial statements in accordance with Rules 5-04 and 12-04 of Regulation S-X, as the restricted net assets of ProFrac LLC and its consolidated subsidiaries exceed 25 % of the consolidated net assets of ProFrac Corp. This information should be read in conjunction with the consolidated financial statements and the accompanying notes of ProFrac Corp. included in the Company's Annual Report on Form 10-K. For purposes of these condensed financial statements, the Company's majority owned subsidiaries are recorded based upon its proportionate share of the subsidiaries' net assets.
 Company Formation
 ProFrac Corp. was incorporated as a Delaware corporation on August 17, 2021, to become a holding corporation for ProFrac LLC and its subsidiaries upon completion of a corporate reorganization in conjunction with a planned initial public offering ("IPO"). On May 17, 2022, ProFrac Corp. completed its IPO and corporate reorganization and became the managing member of ProFrac LLC.
 The condensed parent company financial statements presented herein are those of ProFrac Corp. subsequent to the corporate reorganization on May 17, 2022, and ProFrac LLC before that date. In these notes to parent company financial statements, ProFrac Corp. and ProFrac LLC together are also referred to as "we," "us," "our," or the "Company" and ProFrac LLC is also referred to as "ProFrac Predecessor." For all periods presented, the parent company financial statements presented herein include the controlled subsidiaries of ProFrac LLC, which include Best Pump & Flow LP ("Best Flow") and Alpine Silica, LLC ("Alpine").
 Prior to December 21, 2021, the Wilks Parties held a controlling interest in each of ProFrac LLC, Best Flow and Alpine. Historical periods for ProFrac Predecessor had been presented on a consolidated and combined basis given the common control ownership by the Wilks Parties. On December 21, 2021, all of the then-outstanding membership interests in Best Flow and Alpine were contributed to ProFrac LLC in exchange for membership interests in ProFrac LLC. Accordingly, the results for the year ended December 31, 2021 have been retrospectively adjusted to present the operations of ProFrac LLC, Best Flow and Alpine on a combined basis. The acquisitions of Best Flow and Alpine have been accounted for in a manner consistent with the pooling of interest method of accounting, as the transaction was a combination of entities under common control. Under this method of accounting, the parent company statements of operations and parent company statements of cash flows have been adjusted to include all activities of the commonly controlled groups for all periods in which common control existed.
 Initial Public Offering
 In the second quarter of 2022, ProFrac Corp. completed its IPO of 18.2 million shares of its Class A common stock, par value $ 0.01 per share (the "Class A Common Stock") at a public offering price of $ 18.00 per share, which generated combined net proceeds of $ 301.7 million, after deducting underwriter discounts and commissions and estimated offering costs. The Company used $ 72.9 million of the net proceeds to redeem the membership ownership interests from the then-existing owners of THRC FTSI Related Equity (as defined in "Notes to the Consolidated Financial Statements – Note 4 – Business Combinations" included in the Company's Annual Report on Form 10-K) and contributed the remaining proceeds to ProFrac LLC.

 Redeemable Noncontrolling Interests
 ProFrac Corp.'s only material asset is an equity interest consisting of units representing limited liability company interests in ProFrac LLC (the "Units"). As the sole managing member of ProFrac LLC, ProFrac Corp. consolidates the financial results of ProFrac LLC and its subsidiaries and reports a noncontrolling interest related to the portion of Units not owned by ProFrac Corp. Historically, the holders of Units not owned by ProFrac Corp. also held shares of ProFrac Corp.'s Class B common stock, such that a single share of Class B common stock was issued for each Unit not owned by ProFrac Corp.
 Pursuant to the Third Amended and Restated Limited Liability Company Agreement of ProFrac LLC and the Second Amended and Restated Certificate of Incorporation of ProFrac Corp., certain members of ProFrac LLC had the right to cause ProFrac LLC to redeem all or a portion of each such member's Units, together with the surrender of the same number of each such member's shares of Class B common stock, for an equivalent number of shares of Class A common stock or, at the election of our board of directors, cash. In connection with the exercise of such redemption, a corresponding number of shares of Class B common stock would be canceled. The redemption election was not considered to be within our control because the holders of Class B common stock and their affiliates controlled us through direct representation on our board of directors. As a result, we have historically presented the noncontrolling interests in ProFrac LLC as redeemable noncontrolling interests outside of permanent equity.
 In April 2023, all the eligible holders of the Units (the "Redeeming Members") submitted redemption notices with respect to all of their Units, representing an aggregate of 104.2 million ProFrac LLC units (the "Redeemed Units"), together with the surrender and delivery of the same number of shares of our Class B common stock. The Redeeming Members include entities owned or affiliated with ProFrac Corp.'s controlling stockholders, Mr. Dan Wilks and Mr. Farris Wilks, as well as Mr. Matthew D. Wilks, our Executive Chairman, an entity affiliated with Mr. Johnathan L. Wilks, our Chief Executive Officer, and Mr. Coy Randle, a member of our board of directors.
 In April 2023, we delivered a written notice to ProFrac LLC and the Redeeming Members setting forth our election to exercise our right to purchase directly and acquire the Redeemed Units, together with the surrender and delivery of the same number of shares of our Class B common stock from the Redeeming Members.
 We subsequently acquired the Redeemed Units from the Redeeming Members by issuing an aggregate of 101.1 million shares of Class A common stock on or about April 10, 2023 and the remaining 3.1 million shares on or about April 13, 2023. The surrendered shares of Class B common stock were canceled, and no shares of our Class B common stock remain issued and outstanding.

 3. INCOME TAXES
 For details regarding income taxes, see "Notes to the Consolidated Financial Statements—NOTE 11 – Income Taxes" included in the Company's Annual Report on Form 10-K.
