(a) Except as may otherwise be provided in this Second Amended and Restated Certificate of Incorporation, each share of Common Stock shall have identical rights and privileges in every respect. Common Stock shall be subject to the express terms of Preferred Stock and any series thereof. Except as may otherwise be provided in this Second Amended and Restated Certificate of Incorporation, in a Preferred Stock Designation or by applicable law, the holders of shares of Common Stock shall be entitled to one vote for each such share on all matters to which stockholders are entitled to vote, the holders of shares of Common Stock shall have the exclusive right to vote for the election of directors and on all other matters upon which stockholders are entitled to vote, and the holders of Preferred Stock shall not be entitled to vote at or receive notice of any meeting of stockholders, other than as provided in any Preferred Stock Designation. Each holder of Common Stock shall be entitled to notice of any stockholders’ meeting in accordance with the bylaws of the Corporation (as in effect at the time in question) and applicable law on all matters put to a vote of the stockholders of the Corporation. Except as otherwise required in this Second Amended and Restated Certificate of Incorporation or by applicable law, the holders of Common Stock shall vote together as a single class on all matters (or, if any holders of Preferred Stock are entitled to vote together with the holders of Common Stock, the holders of Common Stock and the Preferred Stock shall vote together as a single class).

2

(b) Notwithstanding the foregoing, except as otherwise required by applicable law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Second Amended and Restated Certificate of Incorporation (including any Preferred Stock Designation) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Second Amended and Restated Certificate of Incorporation (including any Preferred Stock Designation) or pursuant to the DGCL.

(c) Subject to the prior rights and preferences, if any, applicable to shares of Preferred Stock or any series thereof, the holders of shares of Class A Common Stock shall be entitled to receive ratably in proportion to the number of shares of Class A Common Stock held by them such dividends and distributions (payable in cash, stock or otherwise), if any, as may be declared thereon by the Board at any time and from time to time out of any funds of the Corporation legally available therefor. Dividends and other distributions shall not be declared or paid on the Class B Common Stock unless (i) the dividend consists of shares of Class B Common Stock or of rights, options, warrants or other securities convertible into or exercisable, exchangeable or redeemable for, shares of Class B Common Stock paid proportionally with respect to each outstanding share of Class B Common Stock and (ii) a dividend consisting of shares of Class A Common Stock or of rights, options, warrants or other securities convertible into or exercisable, exchangeable or redeemable for, shares of Class A Common Stock on equivalent terms is simultaneously paid to the holders of Class A Common Stock. If dividends are declared on the Class A Common Stock or the Class B Common Stock that are payable in shares of Common Stock, or securities convertible into, or exercisable, exchangeable or redeemable for, Common Stock, the dividends payable to the holders of Class A Common Stock shall be paid only in shares of Class A Common Stock (or securities convertible into, or exercisable, exchangeable or redeemable for, Class A Common Stock), the dividends payable to the holders of Class B Common Stock shall be paid only in shares of Class B Common Stock (or securities convertible into, or exercisable, exchangeable or redeemable for, Class B Common Stock), and such dividends shall be paid in the same number of shares (or fraction thereof) on a per share basis of the Class A Common Stock and Class B Common Stock, respectively (or securities convertible into, or exercisable, exchangeable or redeemable for, the same number of shares (or fraction thereof) on a per share basis of the Class A Common Stock and Class B Common Stock, respectively). In no event shall the shares of either Class A Common Stock or Class B Common Stock be split, divided, or combined unless the outstanding shares of the other class shall be proportionately split, divided or combined.

(d) In the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Corporation, after distribution in full of the preferential amounts, if any, to be distributed to the holders of shares of Preferred Stock or any series thereof, the holders of shares of Class A Common Stock shall be entitled to receive all of the remaining assets of the Corporation available for distribution to its stockholders, ratably in proportion to the number of shares of Class A Common Stock held by them. The holders of shares of Class B Common Stock, as such, shall not be entitled to receive any assets of the Corporation in the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation. A dissolution, liquidation or winding-up of the Corporation, as such terms are used in this paragraph (d), shall not be deemed to be occasioned by or to include any consolidation or merger of the Corporation with or into any other corporation or corporations or other entity or a sale, lease, exchange or conveyance of all or a part of the assets of the Corporation.

(e) Shares of Class B Common Stock may be issued or transferred only in connection with the simultaneous issuance or transfer of an identical number of Units (as defined below). Any purported issuance or transfer of shares of Class B Common Stock not accompanied by an issuance or transfer of the identical number of Units shall be null and void and of no force or effect, and the shares of Class B Common Stock so issued or transferred shall automatically and without further action on the part of the Corporation or any holder of Class B Common Stock be transferred to the Corporation and cancelled for no consideration and thereupon shall be retired. For this purpose “Unit” means a membership interest of ProFrac Holdings, LLC, a Delaware limited liability company, or any successor entity, that constitutes a “Unit” as defined in the Third Amended and Restated Limited Liability Company Agreement of ProFrac Holdings, LLC, dated as of May 17, 2022, or the limited liability company agreement or other similar document of such successor entity, as the relevant agreement may be further amended, restated, supplemented and otherwise modified from time to time (the “LLC Agreement”).

(f) The Corporation will at all times reserve and keep available out of its authorized but unissued shares of Class A Common Stock, such number of shares of Class A Common Stock that shall from time to time be sufficient to effect the redemption of all outstanding Units that are subject to the Redemption Right (as defined in the LLC

3

Agreement) for shares of Class A Common Stock; provided that nothing contained herein shall be construed to preclude the Corporation from satisfying its obligations in respect of any such redemption by delivery of cash in lieu of shares of Class A Common Stock in the amount permitted by and provided in the LLC Agreement or shares of Class A Common Stock which are held in the treasury of the Corporation. All shares of Class A Common Stock that shall be issued upon any such redemption will, upon issuance in accordance with the LLC Agreement, be validly issued, fully paid and non-assessable.

(g) No stockholder shall, by reason of the holding of shares of any class or series of capital stock of the Corporation, have any preemptive or preferential right to acquire or subscribe for any shares or securities of any class, whether now or hereafter authorized, which may at any time be issued, sold or offered for sale by the Corporation, unless specifically provided for in the terms of a series of Preferred Stock.

3. The number of authorized shares of Class A Common Stock, Class B Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority in voting power of the outstanding shares of stock of the Corporation entitled to vote thereon, and no vote of the holders of Class A Common Stock, Class B Common Stock or Preferred Stock, or of any series thereof, voting separately as a class shall be required therefor, irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto).

FIFTH: The business and affairs of the Corporation shall be managed by or under the direction of the Board. Until the first date on which the Principal Stockholders (as such term is defined in the Stockholders’ Agreement among the Corporation and the Principal Stockholders, dated as of May 17, 2022, as it may be amended, restated, supplemented and otherwise modified from time to time (the “Stockholders’ Agreement”)) no longer individually or collectively beneficially own (or otherwise have the right to vote or direct the vote of) more than 50% of the outstanding shares of Common Stock (the “Trigger Date”), the directors, other than those who may be elected by the holders of any series of Preferred Stock specified in the related Preferred Stock Designation, shall consist of a single class, with the initial term of office to expire at the 2023 annual meeting of stockholders, and each director shall hold office until his or her successor shall have been duly elected and qualified, subject, however, to such director’s earlier death, resignation, disqualification or removal. For purposes of this Second Amended and Restated Certificate of Incorporation, beneficial ownership of shares shall be determined in accordance with Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended. Prior to the Trigger Date, at each annual meeting of stockholders, directors elected to succeed those directors whose terms then expire shall be elected for a term of office to expire at the next succeeding annual meeting of stockholders after their election, with each director to hold office until his or her successor shall have been duly elected and qualified, subject, however, to such director’s earlier death, resignation, disqualification or removal.

On and after the Trigger Date, the directors, other than those who may be elected by the holders of any series of Preferred Stock specified in the related Preferred Stock Designation, shall be divided, with respect to the time for which they severally hold office, into three classes, with the initial term of office of the first class to expire at the first annual meeting of stockholders following the Trigger Date, the initial term of office of the second class to expire at the second annual meeting of stockholders following the Trigger Date, and the initial term of office of the third class to expire at the third annual meeting of stockholders following the Trigger Date, with each director to hold office until his or her successor shall have been duly elected and qualified, subject, however, to such director’s earlier death, resignation, disqualification or removal, and the Board shall be authorized to assign members of the Board, other than those directors who may be elected by the holders of any series of Preferred Stock, to such classes at the time such classification is to become effective. At each annual meeting of stockholders following the Trigger Date, directors elected to succeed those directors whose terms then expire shall be elected for a term of office to expire at the third succeeding annual meeting of stockholders after their election, with each director to hold office until his or her successor shall have been duly elected and qualified, subject, however, to such director’s earlier death, resignation, disqualification or removal.

Subject to applicable law, the rights of the holders of any series of Preferred Stock then outstanding and the then-applicable terms of the Stockholders’ Agreement, any newly created directorship that results from an increase in the number of directors or any vacancy on the Board that results from the death, resignation, disqualification or removal of any director or from any other cause shall, unless otherwise required by law, be filled (A) prior to the Trigger Date, by the affirmative vote of a majority of the total number of directors then in office, even if less than a

4

quorum, or by a sole remaining director, or by the affirmative vote of the holders of a majority of the voting power of the outstanding shares of stock of the Corporation entitled to vote generally for the election of directors, voting together as a single class and acting at a meeting of the stockholders or by written consent (if permitted) in accordance with the DGCL, this Second Amended and Restated Certificate of Incorporation and the bylaws of the Corporation, and (B) on or after the Trigger Date, solely by the affirmative vote of a majority of the total number of directors then in office, even if less than a quorum, or by a sole remaining director, and shall not be filled by the stockholders. Any director elected to fill a vacancy not resulting from an increase in the number of directors shall hold office for the remaining term of his or her predecessor. No decrease in the number of authorized directors constituting the Board shall shorten the term of any incumbent director.

Prior to the Trigger Date, subject to the rights of the holders of shares of any series of Preferred Stock, if any, to elect directors pursuant to this Second Amended and Restated Certificate of Incorporation (including any Preferred Stock Designation thereunder) and the then-applicable terms of the Stockholders’ Agreement, any director may be removed at any time, either for or without cause, upon the affirmative vote of the holders of a majority of the voting power of the outstanding shares of stock of the Corporation entitled to vote generally for the election of directors, voting together as a single class and acting at a meeting of the stockholders or by written consent (if permitted) in accordance with the DGCL, this Second Amended and Restated Certificate of Incorporation and the bylaws of the Corporation. Notwithstanding the foregoing, in the event that a stockholder party to the Stockholders’ Agreement provides notice to the Corporation to remove a director designated by such stockholder pursuant to the terms of the Stockholders’ Agreement, the Corporation may take all necessary action to cause such removal, to the extent permitted by applicable law.

On and after the Trigger Date, subject to the rights of the holders of shares of any series of Preferred Stock, if any, to elect directors pursuant to this Second Amended and Restated Certificate of Incorporation (including any Preferred Stock Designation thereunder) and the then-applicable terms of the Stockholders’ Agreement, any director may be removed only for cause, upon the affirmative vote of the holders of at least 66 2/3% of the outstanding shares of stock of the Corporation entitled to vote generally for the election of directors, voting together as a single class and acting at a meeting of the stockholders or by written consent (if permitted) in accordance with the DGCL, this Second Amended and Restated Certificate of Incorporation and the bylaws of the Corporation.

Subject to applicable law, the Stockholders’ Agreement and the rights of the holders of any series of Preferred Stock to elect directors under specified circumstances, if any, the number of directors shall be fixed from time to time exclusively pursuant to a resolution adopted by a majority of the Board. Unless and except to the extent that the bylaws of the Corporation so provide, the election of directors need not be by written ballot. There shall be no cumulative voting in the election of directors.

Prior to the Trigger Date, on any matter to be voted on or consented to by the Board (i) each director other than any Farris Director and any THRC Director (as such terms are defined in the Stockholders’ Agreement and each, a “Wilks Director” and, collectively, the “Wilks Directors”) (the “Non-Wilks Directors”) shall be entitled to cast one (1) vote, (ii) the Wilks Directors shall collectively be entitled to cast an aggregate number of votes equal to (x) the total number of directors constituting the entire Board, minus (y) the total number of Wilks Directors then serving on the Board, plus (z) one (1) (such aggregate number of votes, the “Aggregate Wilks Director Voting Power”), such that, at any time, the Wilks Directors in office at such time shall collectively be entitled to cast a majority of the votes that may be cast by the directors, (iii) each Farris Director voting on a matter or participating in a consent shall be entitled to cast a number of votes with respect to such matter (including any fractions thereof) equal to the quotient of (A) one half (1/2) of the Aggregate Wilks Director Voting Power (the “Aggregate Farris Director Voting Power”), divided by (B) the number of Farris Directors voting on such matter or participating in such consent, and (iv) each THRC Director voting on a matter or participating in a consent shall be entitled to cast a number of votes with respect to such matter (including any fractions thereof) equal to the quotient of (A) one half (1/2) the Aggregate Wilks Director Voting Power (the “Aggregate THRC Director Voting Power”), divided by (B) the number of THRC Directors voting on such matter or participating in such consent.

SIXTH: Prior to the Trigger Date, any action required or permitted to be taken at any annual meeting or special meeting of the stockholders of the Corporation may be taken without a meeting, without prior notice and without a vote of stockholders, if a consent or consents, setting forth the action so taken, is or are signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. On and after the Trigger Date, subject to the rights of holders of any series of Preferred Stock with respect to such series of Preferred Stock, any action required or permitted to be taken by the stockholders of the Corporation must be taken at a duly held annual or special meeting of stockholders and may not be taken by any consent of such stockholders.

The authorized person(s) calling a special meeting may fix the date, time and place, if any, of such meeting; provided, however, that if the Secretary of the Corporation is calling a special meeting at the request of the holders of record of more than 50% of the outstanding shares of Common Stock, such stockholders may fix the date, time and place, if any, of such meeting. On and after the Trigger Date, except as otherwise required by law and subject to the rights of the holders of any series of Preferred Stock, the stockholders of the Corporation do not have the power to call a special meeting of stockholders of the Corporation.

Holders of record of more than 50% of the outstanding shares of Common Stock requesting a special meeting may postpone, reschedule or cancel any special meeting of the stockholders previously scheduled by or on behalf of such stockholders.

EIGHTH: In furtherance of, and not in limitation of, the powers conferred by the laws of the State of Delaware, the Board is expressly authorized to adopt, amend or repeal the bylaws of the Corporation without any action on the part of the stockholders of the Corporation; provided, however, that, in addition to any vote of the holders of any class or series of stock of the Corporation required by law or by this Second Amended and Restated Certificate of Incorporation, any bylaw adopted or amended by the Board, and any powers thereby conferred, may be amended, altered or repealed (A) prior to the Trigger Date, by the affirmative vote of holders of not less than 50% in voting power of the then-outstanding shares of stock entitled to vote thereon, voting together as a single class, and (B) on and after the Trigger Date, by the affirmative vote of holders of not less than 66 2/3% in voting power of the then-outstanding shares of stock entitled to vote thereon, voting together as a single class. No bylaws hereafter made or

7

adopted, nor any repeal of or amendment thereto, shall invalidate any prior act of the Board that was valid at the time it was taken.

NINTH:

(a) To the fullest extent permitted by the DGCL, a director or officer of the Corporation shall not be liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL. Any repeal or modification of this paragraph shall not adversely affect any right or protection of a director or officer of the Corporation existing hereunder with respect to any act or omission occurring prior to such repeal or modification.

(b) The Corporation may, to the fullest extent permitted by Section 145 of the DGCL, indemnify any and all persons whom it shall have power to indemnify under said section from and against any and all of the expenses, liabilities or other matters referred to in or covered by said section, and the indemnification provided for herein shall not be deemed exclusive of any other rights to which a person indemnified may be entitled under the bylaws of the Corporation or any agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

TENTH: To the fullest extent permitted by applicable law, the Corporation, on behalf of itself and its subsidiaries, renounces any interest or expectancy of the Corporation and its subsidiaries in, or in being offered an opportunity to participate in, any business opportunities that are from time to time presented to any of the Principal Stockholders or any of their respective affiliates or any of their respective agents, shareholders, members, partners, directors, officers, employees, affiliates or subsidiaries (other than the Corporation and its subsidiaries), including any director or officer of the Corporation who is also an agent, shareholder, member, partner, director, officer, employee, affiliate or subsidiary of any Principal Stockholder (each, a “Business Opportunities Exempt Party”), even if the business opportunity is one that the Corporation or its subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and no Business Opportunities Exempt Party shall have any duty to communicate or offer any such business opportunity to the Corporation or be liable to the Corporation or any of its subsidiaries or any stockholder, including for breach of any fiduciary or other duty, as a director or officer or controlling stockholder or otherwise, and the Corporation shall indemnify each Business Opportunities Exempt Party against any claim that such person is liable to the Corporation or its stockholders for breach of any fiduciary duty, by reason of the fact that such person (i) participates in, pursues or acquires any such business opportunity, (ii) directs any such business opportunity to another person or (iii) fails to present any such business opportunity, or information regarding any such business opportunity, to the Corporation or its subsidiaries, unless, in the case of a person who is a director or officer of the Corporation, such business opportunity is expressly offered to such director or officer in writing solely in his or her capacity as a director or officer of the Corporation.

Neither the amendment nor repeal of this Article Tenth, nor the adoption of any provision of this Second Amended and Restated Certificate of Incorporation or the bylaws of the Corporation, nor, to the fullest extent permitted by Delaware law, any modification of law, shall eliminate, reduce or otherwise adversely affect any right or protection of any person granted pursuant hereto existing at, or arising out of or related to any event, act or omission that occurred prior to, the time of such amendment, repeal, adoption or modification (regardless of when any proceeding (or part thereof) relating to such event, act or omission arises or is first threatened, commenced or completed).

If any provision or provisions of this Article Tenth shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever, (a) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Article Tenth (including, without limitation, each portion of any paragraph of this Article Tenth containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and (b) to the fullest extent possible, the provisions of this Article Tenth (including, without limitation, each such portion of any paragraph of this Article Tenth containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Corporation to protect its directors, officers, employees and agents from personal

8

liability in respect of their good faith service to or for the benefit of the Corporation to the fullest extent permitted by applicable law.

This Article Tenth shall not limit any protections or defenses available to, or indemnification or advancement rights of, any director or officer of the Corporation under this Second Amended and Restated Certificate of Incorporation, the bylaws of the Corporation, applicable law, or otherwise. To the fullest extent permitted by law, any person or entity purchasing or otherwise acquiring any interest in any securities of the Corporation shall be deemed to have notice of and to have consented to the provisions of this Article Tenth.

ELEVENTH: The Corporation shall not be governed by or subject to the provisions of Section 203 of the DGCL, or any successor statute thereto.

TWELFTH: The Corporation shall have the right, subject to any express provisions or restrictions contained in this Second Amended and Restated Certificate of Incorporation or the bylaws of the Corporation, from time to time, to amend this Second Amended and Restated Certificate of Incorporation or any provision hereof in any manner now or hereafter provided by applicable law, and all rights and powers of any kind conferred upon a director or stockholder of the Corporation by this Second Amended and Restated Certificate of Incorporation or any amendment hereof are subject to such right of the Corporation.

THIRTEENTH: Notwithstanding any other provision of this Second Amended and Restated Certificate of Incorporation or the bylaws of the Corporation (and in addition to any other vote that may be required by applicable law or this Second Amended and Restated Certificate of Incorporation), (i) prior to the Trigger Date, the affirmative vote of the holders of a majority in voting power of the outstanding shares of stock of the Corporation entitled to vote thereon, voting together as a single class, shall be required to amend, alter or repeal any provision of this Second Amended and Restated Certificate of Incorporation, and (ii) on and after the Trigger Date, the affirmative vote of the holders of at least 66 2/3% in voting power of the outstanding shares of stock of the Corporation entitled to vote thereon, voting together as a single class, shall be required to amend, alter or repeal any provision of this Second Amended and Restated Certificate of Incorporation.

FOURTEENTH: Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware, or, if such court does not have subject matter jurisdiction thereof, the federal district court of the State of Delaware, shall, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, employee or stockholder of the Corporation to the Corporation or the Corporation’s stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, this Second Amended and Restated Certificate of Incorporation or the Corporation’s bylaws (as either may be amended or restated) or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, or (iv) any action asserting a claim governed by the internal affairs doctrine, in each such case subject to said Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. The federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. To the fullest extent permitted by law, any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article Fourteenth.

If any provision or provisions of this Article Fourteenth shall be held to be invalid, illegal or unenforceable as applied to any person or entity or circumstance for any reason whatsoever, then, to the fullest extent permitted by law, the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Article Fourteenth (including, without limitation, each portion of any sentence of this Article Fourteenth containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) and the application of such provision to other persons or entities and circumstances shall not in any way be affected or impaired thereby. The provisions of this Article Fourteenth shall not apply to actions brought to enforce any liability or duty created by the Securities Exchange Act of 1934, as amended.

To the fullest extent permitted by law, if any action the subject matter of which is within the scope of the first paragraph of this Article Fourteenth is filed in a court other than a court located within the State of Delaware (a

9

“Foreign Action”) in the name of any stockholder, such stockholder shall be deemed to have consented to (A) the personal jurisdiction of the state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce the first paragraph of this Article Fourteenth (an “FSC Enforcement Action”) and (B) having service of process made upon such stockholder in any such FSC Enforcement Action by service upon such stockholder’s counsel in the Foreign Action as agent for such stockholder.

FIFTEENTH: For as long as the Stockholders’ Agreement remains in effect, to the fullest extent permitted by law, in the event of any conflict between the terms and provisions of this Second Amended and Restated Certificate of Incorporation and those contained in the Stockholders’ Agreement, the terms and provisions of the Stockholders’ Agreement shall govern and control except as provided otherwise by mandatory provisions of the DGCL.
