Austin, Texas 78730

Ladies and Gentlemen:

We have acted as counsel for Atlas Energy Solutions, Inc., a Delaware corporation (the “Company”), as successor to Atlas Energy Solutions, Inc. (“Predecessor Atlas”) in connection with the Company’s filing with the Securities and Exchange Commission (the “SEC”) of the Post-Effective Amendment No. 1 to Registration Statement on Form S-8 (File No. 333-270507) (the “Post-Effective Amendment”) under the Securities Act of 1933, as amended (the “Act”), with respect to the Reorganization (as defined below).

As part of an internal reorganization of Predecessor Atlas, the Company replaced the predecessor entity as the new publicly-traded company on the New York Stock Exchange (the “Reorganization”) pursuant to that certain master reorganization agreement, dated as of July 31, 2023 (the “MRA”), the closing of which occurred on October 2, 2023. As a result of the Reorganization, each of the issued and outstanding Class A Common Stock, par value $0.01 per share, of the Company’s predecessor entity was exchanged for one share of the Company’s Common Stock and the holders of Existing Class A Shares at such time became stockholders of the Company. In connection with the Reorganization, the Company assumed and adopted the Atlas Energy Solutions Inc. Long Term Incentive Plan (the “Plan”) and outstanding awards thereunder and as a result, shares of Company Common Stock (the “Shares”) are issuable pursuant thereto.

In reaching the opinions set forth herein, we have examined and are familiar with originals or copies, certified or otherwise identified to our satisfaction, of such documents and records of the Company and such statutes, regulations and other instruments as we deemed necessary or advisable for purposes of this opinion, including (i) the Post-Effective Amendment, (ii) certain resolutions adopted by the board of directors of the Company, (iii) the Plan, and (iv) such other certificates, instruments, and documents as we have considered necessary for purposes of this opinion. As to any facts material to our opinions, we have made no independent investigation or verification of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials and officers or other representatives of the Company.

We have assumed (i) the legal capacity of all natural persons, (ii) the genuineness of all signatures, (iii) the authority of all persons signing all documents submitted to us on behalf of the parties to such documents, (iv) the authenticity of all documents submitted to us as originals, (v) the conformity to authentic original documents of all documents submitted to us as copies, (vi) that all information contained in all documents reviewed by us is true, correct and complete, and (vii) that the Shares will be issued in accordance with the terms of the Plan.
