Dear USA Rare Earth, Inc. Stockholders:

You are cordially invited to attend a special meeting (the “Special Meeting”) of the stockholders of USA Rare Earth, Inc. (“USAR,” the “Company,” “we” or “our”), which will be held virtually on July 1, 2025, at 9:00 a.m. Central Time, via live audio webcast at https://www.cstproxy.com/usare/2025.

Our board of directors has called the Special Meeting to ask our stockholders to consider, vote upon and approve:

• in accordance with Nasdaq Listing Rule 5635(d), the issuance of up to 10,714,286 shares of our common stock pursuant to a warrant (the “Common Warrant”) issued to an institutional investor (the “Purchaser”) in connection with our private placement transaction which closed on May 2, 2025 (the “Warrant Share Issuance Proposal”); and

• the adjournment of the Special Meeting to a later date, if necessary or appropriate, to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of the Warrant Share Issuance Proposal (the “Adjournment Proposal”).

The accompanying Proxy Statement provides you with detailed information about the Special Meeting and the Warrant Share Issuance Proposal and Adjournment Proposal to be voted on at the Special Meeting. We encourage you to read carefully the entire Proxy Statement. Only stockholders of record at the close of business on May 23, 2025 are entitled to notice of, and to vote at, the Special Meeting and any adjournment or postponement thereof.

Holders of our outstanding shares of our common stock, par value $0.0001 per share (“Common Stock”) and our 12% Series A Cumulative Convertible Preferred Stock, par value $0.0001 per share (“Series A Preferred Stock”) as of the record date, May 23, 2025, present virtually or by proxy at the Special Meeting are entitled to vote on the matters presented at the Special Meeting. Holders of our Common Stock and Series A Preferred Stock (on an as converted basis) will vote as a single class on each matter presented at the Special Meeting. The Warrant Share Issuance Proposal and the Adjournment Proposal must be approved by the majority of the votes properly cast (excluding any abstentions or broker non-votes). As of the record date, May 23, 2025, the shares of Common Stock are entitled to one vote per share and the shares of Series A Preferred Stock are entitled to approximately 1.7543 votes per share. Certain stockholders of the Company, including certain of our directors or officers, collectively representing at least a majority of the voting power of the Company’s outstanding stock, have executed and delivered stockholder support agreements pursuant to which such stockholders agreed with the Purchaser to vote all of the shares of Common Stock and Series A Preferred Stock outstanding and beneficially owned by them in favor of the Warrant Share Issuance Proposal at the Special Meeting. Our board of directors unanimously recommends that stockholders vote in favor of the Warrant Share Issuance Proposal and the Adjournment Proposal.

Your vote is very important regardless of the number of shares of Common Stock and/or Series A Preferred Stock that you own. Whether or not you expect to virtually attend the Special Meeting, please submit your proxy or voting instructions as soon as possible by internet, telephone or mail, in the manner described in the Proxy Statement, so that your shares may be represented at the Special Meeting. Returning the proxy does not deprive you of your right to attend the Special Meeting and to vote your shares virtually.

Thank you for your cooperation and continued support.

Sincerely,

/s/ Joshua Ballard

PROXY STATEMENT FOR SPECIAL MEETING OF STOCKHOLDERS

To be Held Virtually at https://www.cstproxy.com/usare/2025
On July 1, 2025, at 9:00 A.M. Central Time

GENERAL INFORMATION

Why am I receiving these proxy materials?

USA Rare Earth, Inc. (“USAR,” the “Company,” “we” or “our”) is providing this Proxy Statement and proxy card, or for shares held in street name (held for your account by a broker or other nominee), voting instruction form (the “proxy materials”), to its stockholders to help them decide how to vote their shares of our common stock, par value $0.0001 per share (“Common Stock”) and/or shares of our 12% Series A Cumulative Convertible Preferred Stock, par value $0.0001 per share (“Series A Preferred Stock”), with respect to: (i) a proposal to approve, in accordance with Nasdaq Listing Rule 5635(d), the issuance of up to 10,714,286 shares of common stock pursuant to a warrant (the “Common Warrant”) issued to an institutional investor in connection with our private placement transaction which closed on May 2, 2025 (the “Private Placement”) (this proposal, the “Warrant Share Issuance Proposal”) and (ii) a proposal to approve the adjournment of the Special Meeting to a later date, if necessary or appropriate, to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of the Warrant Share Issuance Proposal (this proposal, the “Adjournment Proposal”), both as more fully described herein, to be considered at the special meeting of the Company’s stockholders to be held on July 1, 2025, which we refer to as the “Special Meeting.” You should read these materials carefully.

Who can vote at the Special Meeting?

The Board has fixed the close of business on May 23, 2025, as the record date for determining stockholders entitled to notice of and to vote at the Special Meeting and any adjournment or postponement thereof.

Excluding shares held by the Purchaser, a total of 82,486,377 shares of the Company’s Common Stock and 5,018,834 shares of the Company’s Series A Preferred Stock were outstanding on the record date and are entitled to be voted at the Special Meeting. Holders of our Common Stock and Series A Preferred Stock (on an as converted basis) will vote as a single class on each matter presented at the Special Meeting. The Warrant Share Issuance Proposal and Adjournment Proposal must be approved by the majority of the votes properly cast (excluding any abstentions or broker non-votes). As of the record date, May 23, 2025, the shares of Common Stock are entitled to one vote per share and the shares of Series A Preferred Stock are entitled to approximately 1.7543 votes per share. There is no cumulative voting.

In accordance with Nasdaq Listing Rule 5635, and the interpretive material thereunder, the Purchaser will not be entitled to vote the shares of Common Stock issued to it in the Private Placement on the Warrant Share Issuance Proposal.

How do I vote?

If you are a stockholder of record and your shares of Common Stock and/or Series A Preferred Stock are registered directly in your name, you may vote:

• By Internet. You may vote by proxy via the internet at https://www.cstproxy.com by following the instructions at such site. You must have the control number that is included on the proxy card when voting.

• By Telephone. If you live in the United States or Canada, you may vote by proxy by calling toll-free at 1-866-894-0536 and by following the instructions provided by prompt. You must have the control number that is included on the proxy card when voting.

Table of Contents

• By Mail or E-mail. Complete and mail your proxy card in the postage prepaid envelope you receive, and return the proxy card to: Continental Stock Transfer & Trust Co. at 1 State Street, Floor 30, New York, New York 10275-0741. You can also complete your proxy card and send it via email to: proxy@continentalstock.com. Your proxy will be voted in accordance with your instructions. If you sign and return the enclosed proxy but do not otherwise specify how you want your shares voted, they will be voted “FOR” the approval of the Warrant Share Issuance Proposal and the Adjournment Proposal, and will be voted according to the discretion of the proxy holder named in the proxy card upon any other business that may properly be brought before the Special Meeting and at all postponements thereof.

If your shares of Common Stock are held in street name (held for your account by a broker or other nominee), you may vote:

• By Internet or by Telephone. You will receive instructions from your broker or other nominee if you are permitted to vote by internet or telephone.

• By Mail. You will receive instructions from your broker or other nominee explaining how to vote your shares.

What are the Board’s recommendations on how to vote my shares?

The Board unanimously recommends a vote:

• Proposal 1: “FOR” the approval of the Warrant Share Issuance Proposal.

• Proposal 2: “FOR” the approval of the Adjournment Proposal.

Who pays the cost for soliciting proxies?

This proxy is solicited on behalf of the Board of USA Rare Earth, Inc. The Company will bear the cost of solicitation of proxies. This includes the charges and expenses of brokerage firms and others for forwarding solicitation material to beneficial owners of our outstanding Common Stock. The Company may solicit proxies by mail, personal interview, telephone or via the internet through its officers, directors and other management employees, who will receive no additional compensation for their services.

Can I change or revoke my vote?

You may revoke your proxy at any time before it is voted by notifying David Kronenfeld, the Secretary of the Company, in writing delivered to the Company’s principal executive offices, by returning a signed proxy with a later date, by transmitting a subsequent vote over the internet or by telephone prior to the close of the internet voting facility or the telephone voting facility, or by attending the Special Meeting and voting electronically. If your shares of Common Stock are held in street name, you must contact your broker or nominee for instructions as to how to change or revoke your vote.

How is a quorum reached?

The presence, virtually or by proxy, of holders of at least a majority in voting power of the shares of stock issued and outstanding and entitled to vote at the Special Meeting is necessary to constitute a quorum for the transaction of business at the Special Meeting. Abstentions and “broker non-votes,” if any, will be counted as present and entitled to vote for purposes of determining whether a quorum is present for the transaction of business at Special Meeting, but will have no effect on the outcome of the proposals.

“Broker non-votes” are shares represented at the Special Meeting held by brokers, bankers or other nominees (i.e., in “street name”) and do not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner. Generally, brokerage firms may vote to ratify the selection of independent auditors and on other “discretionary” or “routine” items. In contrast, brokerage firms may not vote to elect directors, because those proposals are considered “non-discretionary” items. Accordingly, if you do not instruct your broker how to vote your shares on “non-discretionary” matters, your broker will not be permitted to vote your shares on these matters. This is a “broker non-vote.”

Table of Contents

What vote is required to approve each item?

Warrant Share Issuance Proposal (Proposal No. 1). The affirmative vote of the majority of the votes properly cast (excluding any abstentions or broker non-votes), is required to approve the Warrant Share Issuance Proposal. Abstentions and broker non-votes are treated as present and entitled to vote and, therefore, will be counted in connection with the determination of whether a valid quorum is established, but will have no effect on the outcome of the Warrant Share Issuance Proposal. As noted above and discussed further below, stockholder support agreements have previously been entered into with respect to the Warrant Share Issuance Proposal.

Certain stockholders of the Company, including certain of our directors or officers, collectively representing at least a majority of the voting power of the Company’s outstanding stock, executed and delivered stockholder support agreements pursuant to which the stockholders agreed with the Purchaser to vote all of the shares of Common Stock and/or Series A Preferred Stock outstanding and beneficially owned by them in favor of the Warrant Share Issuance Proposal at the Special Meeting.

Adjournment Proposal (Proposal No. 2). The affirmative vote of the majority of the votes properly cast (excluding any abstentions or broker non-votes), is required to approve the Adjournment Proposal. Abstentions and broker non-votes (if any) will be treated as present and entitled to vote and, therefore, will be counted in connection with the determination of whether a valid quorum is established, but will have no effect on the outcome of the Adjournment Proposal.

Holders of the Common Stock and/or Series A Preferred Stock will not be entitled to appraisal, dissenters’ or similar rights in connection with the matters to be voted on at the meeting.

What happens if the Special Meeting is postponed or adjourned?

If the Special Meeting is postponed or adjourned, at any subsequent reconvening of the Special Meeting, your proxy will be voted in the same manner as it would have been voted at the original convening of the Special Meeting unless you withdraw or revoke your proxy.

What happens if stockholder approval of the Warrant Share Issuance Proposal is not obtained at the Special Meeting?

If, despite the Company’s reasonable best efforts, stockholder approval is not obtained at the Special Meeting for the Warrant Share Issuance Proposal, the Company is required to cause an additional special meeting of stockholders to be held on or prior to September 30, 2025. If, despite the Company’s reasonable best efforts stockholder approval is not obtained after such subsequent stockholder meeting, the Company is required to continue to cause an additional stockholder meeting to be held semi-annually thereafter until such stockholder approval is obtained.

What happens if I sell my shares after the record date but before the Special Meeting?

If you transfer any of your shares of Common Stock and/or Series A Preferred Stock after the record date but before the date of the Special Meeting, you will retain your right to vote at the Special Meeting.

Could other matters be decided at the Special Meeting?

No business may be transacted at the Special Meeting except that referred to in the Notice of the Special Meeting, or in a supplemental notice given also in compliance with the provisions of the Company’s By-laws, or such other business as may be germane or supplementary to the business that is stated in the Notice of the Special Meeting or any supplemental notice. The Company does not know of any other matters that may be presented for action at the Special Meeting other than the Warrant Share Issuance Proposal and the Adjournment Proposal.

What does it mean if I receive more than one proxy card or voting instruction form?

It means that you have multiple accounts at the transfer agent or with brokers. Please complete and return all proxy cards or voting instruction forms to ensure that all of your shares are voted.

Table of Contents

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

The preliminary voting results will be announced at the Special Meeting if known at that time, or otherwise will be disclosed on a Current Report on Form 8-K within four business days after the date of the Special Meeting. The final voting results will be disclosed on an amendment to the Current Report on Form 8-K within four business days after the final voting results are known. All reports the Company files with the U.S. Securities and Exchange Commission (the “SEC”) are publicly available when filed.

Who should I call if I have any additional questions?

If you hold your shares directly, please call David Kronenfeld, Chief Legal Officer and Corporate Secretary of the Company, at (813) 867-6155. If your shares of Common Stock are held in street name, please contact the telephone number provided on your voting instruction form or contact your broker or nominee holder directly.

PROPOSAL 1 — THE WARRANT SHARE ISSUANCE PROPOSAL

Background

On May 2, 2025 (the “Closing Date”), the Company consummated the Private Placement with a single institutional investor (the “Purchaser”), raising total gross proceeds of $75,000,000. The Private Placement was consummated pursuant to a securities purchase agreement, dated April 29, 2025 (as amended and restated, the “Securities Purchase Agreement”), which provided for the private placement of: (i) 8,550,400 shares of Common Stock; (ii) a pre-funded warrant to purchase an aggregate of 2,163,886 shares of Common Stock and (iii) a warrant (the “Common Warrant”) to purchase 10,714,286 shares of Common Stock at an exercise price of $7.00 per share (the shares underlying the Common Warrant, the “Common Warrant Shares”), for an aggregate purchase price of $75,000,000.

The Warrant

The Common Warrant entitles the holder thereof (the “Holder”) to purchase up to an aggregate of 10,714,286 shares of the Company’s Common Stock for a period of six years at an exercise price of $7.00 per share, subject to adjustment as described below. The Common Warrant provides for cashless exercise under certain conditions. The Common Warrant also may require payments to be made by the Company for failure to deliver the shares of Common Stock issuable upon exercise.

The exercise price of the Common Warrant and the number of shares issuable upon exercise of the Common Warrant are subject to adjustments for stock dividends, issuances, splits, combinations or similar events. In addition, except in the case of issuances of certain excluded securities, if the Company issues common stock, options or common stock equivalents at a price less than the then-current exercise price of the Common Warrant, the exercise price of the Common Warrant is reduced to that lower price.

If the Company issues Common Stock or rights to purchase stock, warrants, securities or other property pro-rata to holders of its Common Stock, the Holder shall have the right to acquire the same as if it had exercised the Common Warrant. If the Company declares or makes any dividend or other distribution of its assets (or rights to acquire its assets) to holders of its Common Stock, the Holder shall be entitled to participate in such distribution the same as if it had exercised the Common Warrant.

The Holder is also entitled to certain rights in the event of certain fundamental transactions of the Company, including but not limited to: (i) any merger or consolidation in which the Company is not the surviving entity; (ii) the direct or indirect, sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of the Company’s assets; (iii) a purchase offer, tender offer or exchange offer; (iv) any reclassification, reorganization or recapitalization of the Company’s Common Stock; or (v) a stock or share purchase agreement or other business combination whereby more than 50% of the outstanding shares of the Company’s Common Stock or more than 50% of the voting power of the common equity of the Company is acquired. These rights include that upon any subsequent exercise of the Common Warrant after a fundamental transaction, the Holder shall have the right to receive, for each warrant share that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, at the option of the Holder, the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration receivable as a result of such fundamental transaction by a holder of the number of shares of Common Stock for which the Common Warrant was exercisable immediately prior to such fundamental transaction. In addition, in the event of a fundamental transaction, the Company shall, at the Holder’s option, exercisable at any time concurrently with, or within 30 days after, the consummation of the fundamental transaction (or, if later, the date of the public announcement of the applicable fundamental transaction), purchase the Common Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value (as defined in the Common Warrant) of the remaining unexercised portion of the Warrant on the date of the consummation of such fundamental transaction.

Why We Are Seeking Stockholder Approval

Our Common Stock is listed on The Nasdaq Stock Market (“Nasdaq”) under the symbol “USAR.” Because our Common Stock is listed on Nasdaq, we are subject to Nasdaq’s rules and regulations. Nasdaq Listing Rule 5635(d) requires stockholder approval prior to a transaction, other than a public offering, involving the sale, issuance or potential issuance of common stock (or securities convertible into or exercisable for common stock) which alone or together with sales by officers, directors or substantial shareholders of the Company, equals 20% or more of the common stock or 20% or more of the voting power outstanding before the issuance, at a price that is the lower of: (i) the Nasdaq

Table of Contents

Official Closing Price (as reflected on Nasdaq.com) immediately preceding the signing of the binding agreement; or (ii) the average Nasdaq Official Closing Price of the common stock (as reflected on Nasdaq.com) for the five trading days immediately preceding the signing of the binding agreement.

As of April 29, 2025, immediately prior to the signing of the Securities Purchase Agreement, there were 82,068,160 shares of Common Stock outstanding. The aggregate number of shares of Common Stock issued on the Closing Date together with the shares of Common Stock underlying the pre-funded warrant equals 10,714,286 shares, representing 13.1% of the total number of outstanding shares of Common Stock. If the Common Warrant were to have been exercisable, the aggregate number of shares issued on the Closing Date, underlying the pre-funded warrant and underlying the Common Warrant would have represented in excess of 20% of the total number of outstanding shares of Common Stock. In addition, the price per share in the transaction was lower than the average Nasdaq Official Closing Price of our Common Stock for the five trading days immediately preceding the signing of the Securities Purchase Agreement, which was $11.89 per share. Accordingly, the Common Warrant provides that its exercisability is contingent upon receipt of stockholder approval, and we agreed, pursuant to the Securities Purchase Agreement, to file, no later than twenty (20) calendar days after the Closing Date, a preliminary proxy statement for a special meeting of stockholders for the purpose of obtaining the approval of the Company’s stockholders to issue the Common Warrant Shares pursuant to Nasdaq Listing Rule 5635(d), and we agreed to hold such special meeting within twenty (20) calendar days after the expiration of the waiting period for the preliminary proxy statement under Rule 14a-6 under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder, or, if the SEC reviews the proxy statement, the date on which the SEC notifies the Company that it has no further comments on the proxy statement.

We are not seeking the approval of our stockholders to authorize our entry into or consummation of the transactions comprising the Private Placement, as the transactions have already been completed. We are only seeking approval to issue up to an aggregate of 10,714,286 shares of Common Stock upon exercise of the Common Warrant.

Stockholder Support Agreements

Contemporaneously with the execution and delivery of the Securities Purchase Agreement, Michael Blitzer, Chairman of the Board, Paul Kern, a director, Tready Smith, a director, David Kronenfeld, our Chief Legal Officer and Corporate Secretary, Steve Ridge, our Chief Operating Officer, The Critical Minerals Trust, an affiliate of our director Mordechai Gutnick, and certain other stockholders of the Company, collectively representing at least a majority of the voting power of the Company’s outstanding securities, executed and delivered stockholder support agreements pursuant to which such stockholders agreed with the Purchaser to vote all of the shares of Common Stock and/or Series A Preferred Stock outstanding and beneficially owned by them in favor of the Warrant Share Issuance Proposal at the Special Meeting.

As of April 29, 2025, immediately prior to the consummation of the Private Placement, stockholders who signed stockholder support agreements with the Purchaser beneficially owned shares of Common Stock and/or Series A Preferred Stock representing 44,540,271 votes, or approximately 51.0% of the aggregate voting power of our outstanding stock. As of May 23, 2025, the record date, such stockholders beneficially owned shares of Common Stock and/or Series A Preferred Stock representing 45,955,877 votes, or approximately 50.3% of the aggregate voting power of our outstanding stock.

Where You Can Find More Information about the Private Placement, including the Common Warrant

The summaries above, together with the section entitled “General Information,” summarize certain information relating to the Private Placement, and the Common Warrant in particular, but do not contain all of the information that is important to you. For a more complete understanding of the matters to be considered at the Special Meeting, you should read carefully this entire Proxy Statement and the complete copies of the Securities Purchase Agreement, Common Warrant, and the other exhibits that were filed with the Current Report on Form 8-K that we filed with the SEC on April 30, 2025, and the Current Report on Form 8-K that we filed with the SEC on May 5, 2025, which are incorporated herein by reference.

Required Vote

Approval of the Warrant Share Issuance Proposal requires that the majority of the votes properly cast (excluding any abstentions or broker non-votes) vote for approval. Abstentions and broker non-votes are treated as present and entitled to vote and, therefore, will be counted in connection with the determination of whether a valid quorum is established, but will have no effect on the outcome of the Warrant Share Issuance Proposal.

THE BOARD UNANIMOUSLY RECOMMENDS THAT OUR STOCKHOLDERS VOTE “FOR” THE WARRANT SHARE ISSUANCE PROPOSAL.

Table of Contents

PROPOSAL 2 — THE ADJOURNMENT PROPOSAL

Background

Pursuant to the Securities Purchase Agreement, if, despite the Company’s reasonable best efforts, stockholder approval is not obtained at the Special Meeting for the Warrant Share Issuance Proposal, the Company is required to cause an additional special meeting of stockholders to be held on or prior to September 30, 2025. If, despite the Company’s reasonable best efforts stockholder approval is not obtained after such subsequent stockholder meeting, the Company is required to continue to cause an additional stockholder meeting to be held semi-annually thereafter until such stockholder approval is obtained.

The presiding officer of the Special Meeting in his or her capacity as such has the authority to adjourn such meeting in accordance with the Company’s By-laws. In addition, the Board believes that if at the Special Meeting, the number of votes represented by shares of our Common Stock and Series A Preferred Stock, present or represented and voting in favor of the Warrant Share Issuance Proposal, is insufficient to approve the Warrant Share Issuance Proposal or establish a quorum, it is in the best interest of the stockholders to enable the Board to continue to seek to obtain a sufficient number of additional votes to approve the Warrant Share Issuance Proposal.

In the Adjournment Proposal, we are asking stockholders to authorize the holder of any proxy solicited by the Board to vote in favor of adjourning or postponing the Special Meeting or any adjournment or postponement thereof. If our stockholders approve this proposal, we could adjourn or postpone the Special Meeting, and any adjourned session of the Special Meeting, to use the additional time to solicit additional proxies in favor of the Warrant Share Issuance Proposal.

Required Vote

Approval of the Adjournment Proposal requires that the majority of the votes properly cast (excluding any abstentions or broker non-votes) vote for approval. Abstentions and broker non-votes (if any) are treated as present and entitled to vote and, therefore, will be counted in connection with the determination of whether a valid quorum is established, but will have no effect on the outcome of the Adjournment Proposal.

THE BOARD UNANIMOUSLY RECOMMENDS THAT OUR STOCKHOLDERS VOTE “FOR” THE ADJOURNMENT PROPOSAL.

Stockholder Proposals and Nominations

The Company’s By-laws establish an advance notice procedure for stockholders who wish to present a proposal before an annual meeting of stockholders.

Nominations and proposals also must satisfy other requirements set forth in the Company’s By-laws.
