Explanatory Note

This supplement (the “Supplement”) amends and supplements the definitive proxy statement on Schedule 14A (the “Proxy Statement”) filed by Atlas Energy Solutions Inc. (the “Company”) with the U.S. Securities and Exchange Commission (the “SEC”) on March 27, 2026, in connection with the Company’s 2026 Annual Meeting of Stockholders (the “Annual Meeting”) to be held on May 7, 2026, at 8:00 a.m. Central Time.

The changes to the existing disclosure in the Proxy Statement are set forth below under the heading “Revisions to the Proxy Statement.” Capitalized terms not defined in this Supplement are as defined in the Proxy Statement. Other than as set forth below, no other changes have been made to the Proxy Statement and it continues to be in full force and effect as originally filed with the SEC, and the Board of Directors of the Company continues to seek the vote of Company stockholders on each of the proposals to be voted on at the Annual Meeting as recommended in the original filing. From and after the date of this Supplement, any references to the “Proxy Statement” are to the Proxy Statement as amended and supplemented by this Supplement. This Supplement should be read in conjunction with the Proxy Statement and the other proxy materials previously made available to stockholders in connection with the Annual Meeting. If you have already voted your shares, you do not need to vote again unless you would like to change or revoke your prior vote on any proposal.

Revisions to the Proxy Statement

The seventeenth item in the Table of Contents, originally included on page ii of the Proxy Statement, is amended and restated in its entirety to read as follows:

The first sentence of Proposals to be Voted Upon at the Annual Meeting, originally included on page 2 of the Proxy Statement, is amended and restated in its entirety to read as follows:

At the Annual Meeting, our stockholders will be asked to consider and vote upon the following four proposals:

The second to last paragraph of Proposal FOUR — Approval of Atlas Energy Solutions Inc. Employee Stock Purchase Plan, originally included on page 48 of the Proxy Statement, is amended and restated in its entirety to read as follows:

VOTE REQUIRED

Approval of Proposal FOUR requires the affirmative vote of a majority of the shares of Common Stock present in person or represented by proxy and entitled to be voted on the matter at the Annual Meeting. Broker non-votes are not taken into account in determining the outcome of Proposal FOUR, and abstentions will have the effect of a vote against Proposal FOUR.

This Amendment is being filed with the SEC and furnished to shareholders on April 1, 2026.
