Warrior delivered strong full-year results, including record sales volumes, a 21% increase from the prior year, and record production volumes, a 24% increase from the prior year, driven by the meaningful initial contribution from Blue Creek. As Blue Creek ramps toward full production, it is already reshaping our cost structure, enhancing our first-quartile position on the global cost curve, and strengthening our long-term earnings capacity. This world-class mine with an estimated 40-year reserve life will be foundational to our scale, margins, and free cash flow generation for years to come. In addition, the finalization of two federal coal leases with the U.S. Department of Interior and the Bureau of Land Management in 2025 further strengthened our long-term reserve base and enhanced the visibility of our multi-decade growth strategy across Blue Creek and our other operations. We enter 2026 from a position of exceptional strength, supported by expected record volumes, continued cost discipline, prudent capital allocation, and a clear pathway to expanded long-term value creation.

Safety remained the foundation of our operations throughout the year. Warrior achieved another year of safety leadership, with a total incident rate 53% lower than the national average for underground coal mines. We continued to invest in advanced training, technology, and rigorous processes designed to protect our workforce and uphold our strong safety culture. The Board remains deeply committed to overseeing human capital development, workforce well-being, operational safety, and enterprise risk management.

We also strengthened our corporate governance framework and expanded oversight of cybersecurity, regulatory compliance, and other key areas of risk, reflecting our commitment to transparent and responsible leadership. Ongoing engagement with our stockholders continues to inform Board priorities and enhance our governance practices.

With Blue Creek ramping steadily, a strong operational foundation, and a talented and dedicated workforce, Warrior enters 2026 well positioned to continue delivering long-term, sustainable value for our stockholders.

On behalf of the full Board and Warrior team, thank you for your continued support.

Sincerely,

J. Brett Harvey

Chairman

Who is entitled to vote at the Annual Meeting?

You are entitled to vote at the meeting if you were a holder of the Company’s common stock, par value $0.01 per share, as of the close of business on March 3, 2026 (the “Record Date”). Our common stock is our only authorized and issued voting security. Each share of common stock is entitled to one vote on each proposal presented during the Annual Meeting.

How many shares are eligible to vote?

On the Record Date there were 52,799,430 shares of our common stock outstanding and entitled to vote at the Annual Meeting.

What will I be voting on?

You will be voting on the matters listed below (with the Board’s recommendations on each matter):

What is the difference between holding shares as a stockholder of record and as a beneficial owner?

Most stockholders of the Company hold their shares through a broker, bank or other nominee rather than directly in their own name. As summarized below, there are some differences between shares held of record and those owned beneficially.

Stockholder of Record: If your shares are registered directly in your name with the Company’s transfer agent, Equiniti Trust Company, LLC, you are considered the stockholder of record with respect to those shares, and the Notice of Annual Meeting of Stockholders is being sent directly to you. As the stockholder of record, you have the right to grant your voting proxy directly to the persons named as proxy holders, J. Brett Harvey and Kelli K. Gant, or to vote during the virtual Annual Meeting. If you request printed copies of the proxy materials, the Company will provide a proxy card for you to use. You may also vote by Internet or by telephone, as described below under the heading “How do I vote?”

Beneficial Owner: If your shares are held in a brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in “street name,” and these proxy materials are being forwarded to you by your broker or nominee who is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you are invited to participate in the virtual Annual Meeting. You also have the right to direct your broker or nominee on how to vote these shares. Your broker or nominee should have enclosed a voting instruction form for you to direct your broker or nominee how to vote your shares. You may also vote by Internet or by telephone, as described below under “How do I vote?” However, shares held in “street name” may be voted during the virtual Annual Meeting by you only if you obtain a signed proxy from the record holder (broker, bank or other nominee) giving you the right to vote the shares.

How do I vote?

You can vote your shares:

Please read the instructions on the Notice, the proxy card or the information sent by your broker, bank or nominee. Mailed proxy cards or voting instruction forms should be returned in the envelope provided to you with your proxy card or voting instruction form, and must be received by April 19, 2026 in order for the vote therein to be counted for the Annual Meeting. An Internet or telephone vote must be received by 11:59 p.m. Eastern Daylight Time on April 19, 2026 in order to be counted for the Annual Meeting. Your vote is

important and we strongly encourage you to vote your shares by following the instructions provided on the enclosed Notice or proxy card. Please vote promptly.

What do I do if my shares are held by a bank or brokerage firm?

If your shares are held by a bank or brokerage firm, your bank or broker will send you a separate package describing the procedure for voting your shares. You should follow the instructions provided by your bank or brokerage firm.

What is the quorum requirement?

The quorum requirement for holding the Annual Meeting and transacting business is the presence, in person or by proxy, of the holders of a majority of the voting power of all outstanding shares of common stock entitled to be voted at such meeting. Abstentions and shares represented by “broker non-votes,” as described below, are counted as present and entitled to vote for the purpose of determining a quorum.

What level of stockholder vote is required to approve each proposal, what are the effects of abstentions and unmarked proxy cards, and is broker discretionary voting allowed?

Each share of our common stock is entitled to one vote with respect to each proposal. The votes required are summarized below:

Can I change my vote?

At any time before the Annual Meeting you may change your vote and revoke your proxy:

If you are a record holder, by:

Kelli K. Gant

Warrior Met Coal, Inc.

16243 Highway 216

Brookwood, Alabama 35444.

If you hold through a broker, bank or other nominee, by:

Participation in the virtual Annual Meeting itself will not revoke a proxy.

Who will count the votes?

The Board appointed Corporate Election Services, Inc. as the Company’s independent proxy tabulator and First Coast Results, Inc. as the Inspector of Election. The Inspector of Election shall have the authority to receive, inspect, electronically tally and determine the validity of the proxies received.

Is my vote confidential?

Proxy instructions, ballots and voting tabulations that identify individual stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed either within the Company or to third parties except (1) as necessary to meet applicable legal requirements, (2) to allow for the tabulation of votes and certification of the vote and (3) to facilitate a successful proxy solicitation by the Board. Additionally, we will forward to management any written comments you provide on a proxy card or through other means.

What happens if other matters come up during the Annual Meeting?

The matters described in this Proxy Statement are the only matters we know of that will be voted on during the Annual Meeting. If other matters are properly presented during the Annual Meeting and you are a stockholder of record and have submitted a completed proxy card or voting instruction form, the persons named in such proxy card or voting instruction form will vote your shares according to their best judgment.

Are stockholders entitled to appraisal or dissenters’ rights?

Under Delaware law, stockholders are not entitled to appraisal or dissenters’ rights with respect to the proposals presented in this Proxy Statement.

Who pays for the proxy solicitation related to the Annual Meeting?

The cost of soliciting proxies will be borne by the Company. In addition to sending you these materials by mail and electronically, the Company may use the services of its officers and other employees of the Company who will receive no special compensation for their services but may be reimbursed for their out of pocket expenses to contact you personally, by telephone, electronically, in writing or in person. We will also reimburse banks, brokers and other fiduciaries for their reasonable costs in forwarding these materials to the beneficial owners of our common stock. The Company has engaged Sodali & Co to assist with the solicitation of proxies and expects to pay approximately $13,500 for these services, plus expenses.

Where can I find the voting results of the Annual Meeting?

We will announce preliminary voting results during the Annual Meeting and publish preliminary results, or final results if available, in a Current Report on Form 8-K within four business days of the Annual Meeting. If final voting results are unavailable at the time we file the Form 8-K, then we will file an amended report on Form 8-K to disclose the final results within four business days after the final results are known.

How do I obtain a separate set of proxy materials if I share an address with other stockholders?

To reduce expenses, in some cases, we are delivering one Notice or, where applicable, one set of the proxy materials, to certain stockholders who share an address, unless otherwise requested by one or more of the stockholders. For stockholders who request and receive hard copies of the proxy materials, a separate proxy card will be included with the proxy materials for each stockholder. For stockholders receiving a Notice, the Notice will instruct you as to how you may access and review all of the proxy materials on the Internet. The Notice also instructs you as to how you may submit your proxy on the Internet or by telephone. If you have only received one Notice or one set of the proxy materials, you may request separate copies at no additional cost to you by calling us at (205) 554-6150 or by writing to us at Warrior Met Coal, Inc., 16243 Highway 216, Brookwood, Alabama 35444, Attn: Corporate Secretary. If you received a Notice and you would like to receive a paper or email copy of our proxy materials, you should follow the instructions in the Notice for requesting such materials.

You may also request separate paper proxy materials or a separate Notice for future annual meetings by following the instructions in the Notice for requesting such materials, or by contacting us by calling or writing.

If I share an address with other stockholders of the Company, how can we get only one set of voting materials for future meetings?

You may request that we send you and the other stockholders who share an address with you only one Notice or one set of proxy materials by calling us at (205) 554-6150 or by writing to us at Warrior Met Coal, Inc., 16243 Highway 216, Brookwood, Alabama 35444, Attn: Corporate Secretary.

ITEMS OF BUSINESS REQUIRING YOUR VOTE

Proposal 1 — Election of Directors

Our Board of Directors

Our Certificate of Incorporation and Bylaws provide that our Board of Directors consists of a single class of directors and that the terms of office of the directors is one year from the time of their election until the next annual meeting of stockholders and until their successors are duly elected and qualified. In addition, our Certificate of Incorporation and Bylaws provide that, in general, vacancies on our Board may be filled by a majority of directors in office, even if less than a quorum, or by a sole remaining director (and not by the stockholders). Our Certificate of Incorporation provides that the authorized number of directors will be not less than seven nor more than ten, and the exact number of directors will be fixed from time to time exclusively by our Board pursuant to a resolution adopted by a majority of the whole Board. We currently have six directors; accordingly, there is one vacancy on the Board.

The Board of Directors has nominated the six individuals named in this proposal for election as directors to serve on our Board. Each nominee is currently a member of the Board. Directors elected at the Annual Meeting will be elected to hold office until the 2027 Annual Meeting of Stockholders and until their successors are duly elected and qualified. In the event that any nominee is unable or declines to serve as a director at the time of the Annual Meeting, the proxies will be voted for any nominee who is designated by the present Board to fill the vacancy, but in no event may the proxies be voted for more than six nominees. The Company is not aware of any nominee who will be unable or will decline to serve as a director.

Our Board of Directors seeks to ensure that the Board is composed of members whose experience, qualifications, attributes and skills, when taken together, will allow the Board to satisfy its oversight responsibilities effectively in light of the Company’s business and the laws and stock exchange rules that govern its affairs. We have no minimum qualifications for director candidates. In general, however, our Board will review and evaluate both incumbent and potential new directors in an effort to achieve diversity of skills and experience among our directors and in light of the following criteria:

Our Board of Directors has no specific requirements regarding diversity but believes that its membership should reflect a diversity of skills, experience and backgrounds. In assessing the experience, qualifications, attributes and skills that led our Nominating and Corporate Governance Committee and Board of Directors to conclude that each director has the appropriate qualifications to serve as a director of the Company, the Board focused on the information discussed in each of the director nominees’ individual biographies set forth on pages 16 through 21 of this Proxy Statement. Our Nominating and Corporate Governance Committee and Board also considered a number of competencies that they believe each director nominee demonstrates, including a reputation for integrity and honesty, prominence in the businesses, institutions or professions each serves, an ability to exercise sound and independent business judgment, relevant knowledge about the issues affecting the Company’s business and industry, and a commitment of service to the Company and the Board. In evaluating the suitability of the director nominees for re-election, our Nominating and Corporate

Governance Committee also considered each director’s past performance, including attendance at meetings and participation in and contributions to the activities of the Board and its committees, as applicable.

Qualifications and Experience of the Director Nominees

Our Nominating and Corporate Governance Committee and Board believe our director nominees possess the broad and diverse skills, experience and backgrounds required to oversee management of our large, complex global business and to carry out their responsibilities as directors. The following chart provides an overview of the experiences, expertise and skills that allow our directors to effectively oversee our strategy and operations:

The following matrix highlights the mix of key skills and expertise that, among other factors, led our Nominating and Corporate Governance Committee and Board to recommend these nominees for election to the Board. The matrix is intended to depict notable areas of focus for each director nominee, and the absence of a mark does not mean that a particular director does not possess that qualification or skill. The matrix also sets forth other key attributes of our directors, including age, tenure as a director, and other current public company boards.

Nominees for Election to the Board of Directors

These are the nominees for election to the Board, as recommended by the Nominating and Corporate Governance Committee. The stock ownership with respect to each nominee is set forth in the “Security Ownership of Certain Beneficial Owners and Management” table on page 90.
