        <footnote id="F2">Continued from footnote 1) Each Reporting Person disclaims beneficial ownership of all equity securities reported herein except to the extent of its respective pecuniary interest therein, and the filing of this Form 3 shall not be construed as an admission that any such Reporting Person is the beneficial owner of any equity securities covered by this Form 3.</footnote>
        <footnote id="F3">On March 4, 2022, ProFrac Holdings transferred all of its right, title and interest in $20,000,000 in aggregate principal amount of 10% Convertible PIK Notes of the Issuer (the &quot;Notes&quot;) to ProFrac Holdings II, which became the direct holder of the Notes as a result of such transfer.</footnote>
        <footnote id="F4">Subject to earlier conversion in accordance with their terms, the entire outstanding and unpaid principal balance of the Notes, plus any accrued and unpaid interest thereon, will become due and payable to ProFrac Holdings II on February 2, 2023 (the &quot;Maturity Date&quot;) in a number of shares of the Issuer's Common Stock, par value $0.0001 per share (&quot;Common Stock&quot;), equal to the quotient obtained by dividing (a) the amount of such outstanding principal and accrued and unpaid interest through the date immediately prior to the Maturity Date, by (b) the lesser of (i) $1.088125 (the &quot;Conversion Price&quot;) and (ii) $0.8705, in each case, subject to certain anti-dilution adjustments in accordance with its terms.</footnote>
        <footnote id="F5">Subject to the terms and conditions of the Notes, all or any portion of the outstanding principal and accrued and unpaid interest owing under the Notes may be converted at the election of ProFrac Holdings II at any time into a number of shares of Common Stock equal to the quotient obtained by dividing (a) the amount of such outstanding aggregate principal amount plus accrued and unpaid interest through the date immediately prior to the date of conversion, by (b) the Conversion Price.</footnote>
        <footnote id="F6">This number represents the number of shares of Common Stock issuable to ProFrac Holdings II upon conversion of the Notes if ProFrac Holdings II elects to convert the Notes based on the aggregate principal amount of the Notes (as described in footnote 4 above), not including the conversion of any accrued but unpaid interest on any Notes, and the Conversion Price applicable to the Notes (as described in footnote 5 above).</footnote>
