Re: Atlas Energy Solutions Inc. - Lock-Up Agreement (“Lock-Up Agreement”)

Ladies and Gentlemen:

The undersigned understands that Xxxxxxx Xxxxx & Co. LLC, BofA Securities, Inc. and Xxxxx Xxxxxxx & Co., as representatives (the “Representatives”), propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with Atlas Energy Solutions Inc., a Delaware corporation (the “Company”), providing for an initial public offering (“Public Offering”) of shares (the “Shares”) of the Company’s Class A Common Stock (“Class A Stock”) pursuant to a Registration Statement on Form S-1 (the “Registration Statement”) to be filed with the U.S. Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, without the prior written consent of the Representatives, during the period beginning from the date of this Lock-Up Agreement and continuing to and including the date 180 days after the date set forth on the final prospectus used to sell the Shares (the “Lock-Up Period”), the undersigned shall not, and shall not cause or direct any of its affiliates to, (i) offer, sell, contract to sell, pledge, grant any option to purchase, lend or otherwise dispose of any shares of Class A Stock, or any options or warrants to purchase any shares of Class A Stock, or any securities convertible into, exchangeable for or that represent the right to receive shares of Class A Stock, including without limitation the Company’s Class B Common Stock (“Class B Stock”) (such options, warrants or other securities, collectively, “Derivative Instruments”) now owned or hereafter acquired by the undersigned (collectively, the “Restricted Securities”), (ii) engage in any hedging or other transaction or arrangement (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) which is designed to or which

reasonably could be expected to lead to or result in a sale, loan, pledge or other disposition (whether by the undersigned or someone other than the undersigned), or transfer of any of the economic consequences of ownership, in whole or in part, directly or indirectly, of any shares of Class A Stock or Derivative Instruments, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Class A Stock or other securities, in cash or otherwise (any such sale, loan, pledge or other disposition, or transfer of economic consequences, a “Transfer”) or (iii) otherwise publicly announce any intention to engage in or cause any action or activity described in clause (i) above or transaction or arrangement described in clause (ii) above. Except for (x) the transactions on the terms described under “Corporate Reorganization” in the final prospectus and (y) the distribution of securities by and the subsequent liquidation of each of Atlas Sand Holdings, LLC, Atlas Sand Management Company, LLC, Atlas Sand Holdings II, LLC and Atlas Sand Management Company II, LLC (collectively, the “Distributions”) following the completion of the Public Offering, the undersigned represents and warrants that the undersigned is not currently, and has not caused or directed any of its affiliates to be or become, a party to any agreement or arrangement that provides for, is designed to or which reasonably could be expected to lead to or result in any Transfer during the Lock-Up Period. For the avoidance of doubt, the undersigned agrees that the foregoing provisions shall be equally applicable to any issuer-directed Shares the undersigned may purchase in the Public Offering.

If the undersigned is not a natural person, the undersigned represents and warrants that no single natural person, entity or “group” (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), other than a natural person, entity or “group” (as described above) that has executed a Lock-Up Agreement in substantially the same form as this Lock-Up Agreement, beneficially owns, directly or indirectly, 50% or more of the common equity interests, or 50% or more of the voting power, in the undersigned.

If the undersigned is an officer or director of the Company, (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a Transfer of Restricted Securities, the Representatives will notify the Company of the impending release or waiver, and (ii) the Company has agreed or will agree in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives, in their sole discretion, hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a Transfer not for consideration or to an “immediate family member” as defined in FINRA Rule 5130(i)(5) and (b) the transferee has agreed in writing to be bound by the same terms described in this Lock-Up Agreement to the extent and for the duration that such terms remain in effect at the time of the Transfer.

Notwithstanding the foregoing, the undersigned may:

(a) Transfer the undersigned’s Restricted Securities without the prior written consent of the Representatives:

(i) as a bona fide gift or gifts, charitable contributions, or for bona fide estate planning purposes;

(ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, or if the undersigned is a trust, to a trustor or beneficiary of the trust or to the estate of a beneficiary of such trust;

(iii) by xxxx, other testamentary document or intestate succession upon the death of the undersigned;

(iv) to a partnership, limited liability company or other entity of which the undersigned and the immediate family of the undersigned are the legal and beneficial owner of all of the outstanding equity securities or similar interests;

(vi) in connection with a sale of the undersigned’s Shares acquired (A) from the Underwriters in the Public Offering (other than any issuer-directed shares purchased in the Public Offering by an officer or director of the Company) or (B) in open market transactions after the date of the final prospectus related to this Public Offering (the “Public Offering Date”);

(vii) if the undersigned is a corporation, partnership, limited liability company, trust or other business entity, (A) to another corporation, partnership, limited liability company, trust or other business entity that is an “affiliate” (as defined in Rule 405 promulgated under the Securities Act of 1933, as amended) of the undersigned, or to any investment fund or other entity controlling, controlled by, managing or managed by or under common control with the undersigned or affiliates of the undersigned (including, for the avoidance of doubt, where the undersigned is a partnership, to its general partner or a successor partnership or fund, or any other funds managed by such partnership), or (B) as part of a distribution, transfer or disposition without consideration by the undersigned to its stockholders, partners, members or other equity holders,

(viii) in an exchange of any units of Atlas Sand Operating, LLC (“Atlas Operating”) (or securities convertible into, exchangeable for or that represent the right to receive units of Atlas Operating) and a corresponding number of shares of Class B Stock into or for shares of Class A Stock pursuant to the Amended and Restated Limited Liability Company Agreement of Atlas Operating, the distribution of units of Atlas Operating and a corresponding number of shares of Class B Stock to the members of Atlas Operating or other related agreements as described in the final prospectus, provided that any such securities received by the undersigned shall be subject to the terms of this Lock-Up Agreement;

(xii) to the Company in connection with the vesting, settlement or exercise of restricted stock units, options, warrants or other rights to purchase shares of Class A Stock (including, in each case, by way of “net” or “cashless” exercise), including for the payment of exercise price and tax and remittance payments due as a result of the vesting, settlement or exercise of such restricted stock units, options, warrants or rights, provided that any such shares of Class A Stock received upon such exercise, vesting or settlement shall be subject to the terms of this Lock-Up Agreement, and provided further that any such restricted stock units, options, warrants or rights are held by the undersigned pursuant to an agreement or equity awards granted under a stock incentive plan or other equity award plan, each such agreement or plan which is described in the Registration Statement, the Pricing Disclosure Package and the Prospectus;

(xiii) pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction that is approved by the board of directors of the Company and made to all holders of the Company’s capital stock involving a Change of Control (as defined below) of the Company (for purposes hereof, “Change of Control” shall mean the transfer (whether by tender offer, merger, consolidation or other similar transaction), in one transaction or a series of related transactions, to a person or group of affiliated persons, of shares of capital stock if, after such transfer, such person or group of affiliated persons would hold at least a majority of the outstanding voting securities of the Company (or the surviving entity)); provided that in the event that such tender offer, merger, consolidation or other similar transaction is not completed, the undersigned’s Restricted Securities shall remain subject to the provisions of this Lock-Up Agreement;

(xiv) in connection with (x) the transactions on the terms described under “Corporate Reorganization” in the final prospectus and (y) the Distributions; or

The undersigned now has, and, except as contemplated by clauses (i) – (xiv) above, for the duration of this Lock-Up Agreement will have, good and marketable title to the undersigned’s shares of the Company’s securities it holds as of the date hereof, free and clear of all liens, encumbrances and claims whatsoever. In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.
