PROXY STATEMENT — March 31, 2026

This Proxy Statement is furnished in connection with the solicitation by the Board of Directors (the "Board") of NACCO Industries, Inc., a Delaware corporation (the "Company," "NACCO," "we," "our" or "us"), of proxies to be used at the annual meeting of our stockholders to be held on May 15, 2026 (the "Annual Meeting"). This Proxy Statement and the related form of proxy are being mailed to stockholders commencing on or about March 31, 2026.

If the enclosed form of proxy is executed, dated and returned or if you vote electronically, the shares represented by the proxy will be voted as directed on all matters properly coming before the Annual Meeting for a vote. Proxies that are properly signed without any indication of voting instructions will be voted as follows:

The proxies may be revoked at any time prior to their exercise by giving notice to us in writing or by executing and delivering a later-dated proxy. Attendance at the Annual Meeting will not automatically revoke a proxy, but a stockholder of record attending the Annual Meeting may request a ballot and vote in person, thereby revoking a previously granted proxy.

Stockholders of record at the close of business on March 17, 2026 will be entitled to notice of, and to vote at, the Annual Meeting. On that date, we had 5,971,630 outstanding shares of Class A Common Stock, par value $1.00 per share ("Class A Common"), entitled to vote at the Annual Meeting and 1,562,953 outstanding shares of Class B Common Stock, par value $1.00 per share ("Class B Common"), entitled to vote at the Annual Meeting. Each share of Class A Common is entitled to one vote for a nominee for each of the eleven directorships to be filled and one vote on each other matter properly brought before the Annual Meeting. Each share of Class B Common is entitled to ten votes for each such nominee and ten votes on each other matter properly brought before the Annual Meeting. Class A Common and Class B Common will vote as a single class on all matters anticipated to be brought before the Annual Meeting.

At the Annual Meeting, in accordance with Delaware law and our Amended and Restated Bylaws ("Bylaws"), the inspector of election appointed by the Board for the Annual Meeting will determine the presence of a quorum and tabulate the results of stockholder voting. As provided by Delaware law and our Bylaws, the holders of a majority of the outstanding voting power of all classes of our stock, issued and outstanding, and entitled to vote at the Annual Meeting and present in person or by proxy at the Annual Meeting, will constitute a quorum for the Annual Meeting. The inspector of election intends to (1) treat properly executed proxies marked "abstain" as "present" for purposes of determining whether a quorum has been achieved at the Annual Meeting and (2) treat proxies held in "street name" by brokers that are voted on at least one, but not all, of the proposals to come before the Annual Meeting (the "broker non-votes") as "present" for purposes of determining whether a quorum has been achieved at the Annual Meeting.

Proposal 1 is to elect eleven Directors, each for a term of one year and until their respective successors are duly elected and qualified. Our Bylaws provide that our Directors are elected by a plurality vote. Shares for which authority is withheld to vote for Director nominees and broker non-votes will have no effect on the election of Directors except to the extent the failure to vote for a Director nominee results in another nominee receiving a larger number of votes. In accordance with Delaware law and our Bylaws, the eleven Director nominees receiving the greatest number of votes will be elected Directors.

Proposal 2 is to approve NACCO Industries, Inc.'s Amended and Restated Long-Term Incentive Compensation Plan. The New York Stock Exchange ("NYSE") listing standards require the affirmative vote of a majority of votes cast to approve Proposal 2. For purposes of approval under the NYSE listing standards, abstentions and broker non-votes will not be treated as votes cast, so they will not affect the outcome of Proposal 2.

Proposal 3 is an advisory vote on the Company's Named Executive Officer compensation and Proposal 4 is an advisory vote on how often the advisory vote on the Company's Named Executive Officer compensation will occur in the future. We will consider the affirmative vote of the holders of a majority of the votes cast as approval of Proposals 3 and 4. Stockholders may vote for "one year," "two years" or "three years" or may abstain from voting with respect to Proposal 4. With respect to Proposal 4, we expect to be guided by the voting option that receives the greatest number of votes, even if that option does not receive a majority of the votes cast. Although Proposals 3 and 4 are non-binding, the advisory votes allow our stockholders to express their opinions regarding our executive compensation and how frequently an advisory vote on executive compensation should occur. Abstentions and broker non-votes will not be treated as votes cast, so they will not affect the outcome of Proposals 3 and 4.

Proposal 5 is an advisory vote on the ratification of the appointment of EY as our independent registered public accounting firm for 2026. In accordance with our Bylaws, the affirmative vote of the holders of a majority of the votes cast is required to approve all other proposals that are brought before the Annual Meeting, including Proposal 5. As a result, abstentions will not be treated as votes cast, so they will not affect the outcome of Proposal 5. Because the ratification of the appointment of the independent auditor is considered a "routine" matter under the NYSE rules, there will be no broker non-votes with respect to Proposal 5.

We are not aware of any business that may properly be brought before the Annual Meeting other than those matters described in this Proxy Statement. If any matters other than those shown on the proxy card are properly brought before the Annual Meeting, the proxy card gives discretionary authority to the persons named on the proxy card to vote the shares represented by such proxy card. Abstentions and broker non-votes with respect to any other proposal will not be counted for purposes of determining whether a proposal has received the required approval by our stockholders.

In accordance with Delaware law and our Bylaws, we may, by a vote of the stockholders, in person or by proxy, adjourn the Annual Meeting to a later date(s), without changing the record date. If we were to determine that an adjournment was desirable, the appointed proxies would use the discretionary authority granted pursuant to the proxy cards to vote in favor of such an adjournment.
