The Company Materials shall at all times be the property of the Company. Within five days of the Separation Date, Executive shall return to the Company and shall confirm to the Company that Executive has returned any and all Company Materials and any and all copies thereof which are in Executive’s possession, custody, or control, including Company Materials retained by Executive in Executive’s office, automobile, personal electronic devices, or at Executive’s home.

5.Continuing Obligations. Executive acknowledges that the confidentiality, non-solicitation, non-disparagement, non-hire and cooperation provisions to which Executive is subject pursuant to Section 5 of the Employment Agreement (“Continuing Obligations”) survive the termination of Executive’s employment in accordance with their terms and are reasonable and necessary to protect the legitimate business interests of the Company. Executive agrees Executive remains bound by and will continue to comply with such Continuing Obligations. Executive further represents and warrants that Executive has not divulged any confidential information of the Company without the Company’s consent. The Company acknowledges that the non-disparagement covenant in Section 5 of the Employment Agreement and the indemnification provisions in Section 16 of the Employment Agreement and the Indemnification Agreement between the Company and Executive (the “Indemnification Agreement”), survive the termination of Executive’s employment in accordance with their terms.

6.Cooperation.

This requires Executive, without limitation, to (a) make herself available upon reasonable request to provide information and assistance to the Company on such matters without additional compensation, except for Executive’s pre-approved out-of-pocket costs, and (b) notify the Company within three business days of any requests to Executive for information related to any pending or potential legal claim, investigation, or litigation involving the Company or with respect to which the Company is required or requested to provide information, reviewing any such request with a designated representative of the Company prior to disclosing any such information, and permitting the representative of the Company to be present during any communication of such information. Executive’s duty of cooperation will include, but not be limited to (i) meeting with the Company’s legal counsel (including in-house counsel) by telephone or in person at mutually convenient times and places in order to state truthfully Executive’s knowledge of matters at issue and recollection of events; (ii) appearing at the Company’s and/or its legal counsel’s request (including in-house counsel) (and, to the extent possible, at a time convenient to Executive that does not conflict with the needs or requirements of Executive’s then-current employer) as a witness at depositions or trials, without necessity of a subpoena, in order to state truthfully Executive’s knowledge of matters at issue; and (iii) signing at the Company’s and/or its legal counsel’s (including in-house counsel’s) request any declarations or affidavits that truthfully state matters of which Executive has knowledge.

7. Governing Law and Forum Selection. The parties agree that this Retirement Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without reference to its conflict or choice of laws principles. The parties further agree that the exclusive forum for resolution of any dispute arising out of or in connection with this Retirement Agreement, Executive’s employment with the Company, and/or the separation of Executive’s employment from the Company will be in a state or federal court of appropriate jurisdiction in Delaware.

8. Counterparts. This Retirement Agreement may be executed in one or more counterparts (including portable document format (.pdf) counterparts), each of which shall be deemed to be an original, but all of which together will constitute one and the same Retirement Agreement.

9. Severability. To the extent permitted by applicable law, the Company and Executive hereby agree that any term or provision of this Retirement Agreement that renders such term or provision or any other term or provision hereof invalid or unenforceable in any respect shall be severable and shall be modified or severed to the extent necessary to avoid rendering such term or provision invalid or unenforceable, and such modification or severance shall be accomplished in the manner that most nearly preserves the benefit of the parties’ bargain hereunder.

10. Headings; References; Interpretations. Section headings have been inserted for purposes of convenience and shall not be used for interpretive purposes. The words “hereof,” “herein” and “hereunder” and other compounds of the word “here” shall refer to the entire Retirement Agreement and not to any particular provision hereof. The use herein of the word “including” following any general statement, term or matter shall not be construed to limit such statement, term or matter to the specific items or matters set forth immediately following such word or to similar items or matters, whether or not non-limiting language (such as “without limitation”, “but not limited to”, or words of similar import) is used with reference thereto, but rather shall be deemed to refer to all other items or matters that could reasonably fall within the broadest possible scope of such general statement, term or matter. The word “or” as used herein is not exclusive and is deemed to have the meaning “and/or.” All references herein to a law, agreement, instrument or other document shall be deemed to refer to such law, agreement, instrument or other document as amended, supplemented, modified and restated from time to time to the extent permitted by the provisions thereof. Neither this Retirement Agreement nor any uncertainty or ambiguity herein shall be construed against any party, whether under any rule of construction or otherwise. This Retirement Agreement has been reviewed by each of the parties and shall be construed and interpreted according to the ordinary meaning of the words used so as to fairly accomplish the purposes and intentions of the parties.

11. Entire Agreement. This Retirement Agreement, which incorporates the General Release, the Indemnification Agreement and the provisions of Sections 5 and 16 of the Employment Agreement that survive termination of employment pursuant to their terms, is the complete understanding between Executive and the Company regarding the subject matter hereof. It replaces any other agreements, representations or promises, written or oral.

THIS GENERAL RELEASE INCLUDES MATTERS ATTRIBUTABLE TO THE SOLE OR PARTIAL NEGLIGENCE (WHETHER GROSS OR SIMPLE) OR OTHER FAULT, INCLUDING STRICT LIABILITY, OF ANY OF THE RELEASED PARTIES.

(b) The parties intend for this General Release to be interpreted and construed as broadly as it appears on its face and to the broadest and fullest extent permitted under applicable laws.

(c) This General Release requires Executive to abandon all claims or proceedings Executive has against the Released Parties, including those on appeal, if any. If Executive has previously filed a claim against any of the Released Parties in a court of law or initiated a claim or proceeding against or about any of the Released Parties, Executive hereby agrees and covenants to take all steps necessary to cause such claims or proceedings to be dismissed with prejudice within three business days of executing this General Release. If Executive fails to comply with Executive’s obligations under this General Release, Executive agrees to pay all of the Company’s costs and expenses (including reasonable attorneys’ fees) related to the defense of any claims covered by this General Release or any Released Party’s efforts to enforce the terms of this General Release, except that this covenant not to sue does not apply to claims under the OWBPA and the ADEA. Although Executive is releasing claims that Executive may have under the ADEA, Executive may challenge the knowing and voluntary nature of this release before an arbitrator, the Equal Employment Opportunity Commission, or any other federal, state, or local agency charged with the enforcement of any employment laws. This provision is not intended to preclude otherwise available recovery of attorneys’ fees or costs specifically authorized under applicable law.

(d) The foregoing release does not release or impair (i) any rights to vested benefits under an employee benefit plan of any Released Party that is subject to ERISA and that cannot be released pursuant to ERISA, (ii) any claims first arising after the Signing Date or (iii) Executive’s ability to file a claim for unemployment insurance or workers’ compensation benefits or any state disability insurance.

(e) KNOWN AND UNKNOWN CLAIMS. EXECUTIVE UNDERSTANDS THAT THIS GENERAL RELEASE WAIVES AND RELEASES ALL CLAIMS, WHETHER KNOWN OR UNKNOWN, BASED ON FACTS OR OMISSIONS OCCURRING ON OR BEFORE THE DATE THAT EXECUTIVE SIGNS THIS GENERAL RELEASE, EVEN IF EXECUTIVE DOES NOT HAVE KNOWLEDGE OF THOSE FACTS OR OMISSIONS AT THE TIME EXECUTIVE SIGNS THIS GENERAL RELEASE. Executive acknowledges that Executive may later discover claims or facts in addition to or different from those which Executive now knows or believes to exist with regards to the subject matter of this General Release, and which if known or suspected at the time of executing this General Release, may have materially affected its terms. Nevertheless, Executive waives any and all claims that might arise as a result of such different or additional claims or facts.

(f) Protected Rights and Disclosures. Further, nothing in this General Release prevents Executive from filing any non-legally waivable claim, including a challenge to the validity of this General Release, with the Equal Employment Opportunity Commission, the Securities and Exchange Commission, or other federal, state or local governmental agency or commission (collectively “Governmental Agencies”) or participating in (or cooperating with) any investigation or proceeding conducted by any Governmental Agency; however, Executive understands and agrees that, to the extent permitted by law, Executive is waiving any and all rights to recover any monetary or personal relief or recovery from the Released Parties as a result of such Governmental Agency proceeding or subsequent legal actions. Nothing herein waives (and the Released Claims shall not include) Executive’s right to receive an award for information provided to a Governmental Agency (including, for the avoidance of doubt, any monetary award or bounty from any governmental agency or regulatory or law enforcement authority in connection with any protected “whistleblower” activity), and nothing herein or in any other agreement between Executive and any Released Party shall prohibit or restrict Executive from (i) initiating communications directly with, cooperating with, providing information or making statements to, causing information to be provided to, or otherwise assisting in an investigation by, any Governmental Agency; (ii) responding to any inquiry or legal process directed to Executive from any Governmental Agency; (iii) testifying, participating or otherwise assisting in any action or proceeding by any Governmental Agency; (iv) making any disclosures that are protected under the whistleblower provisions of any applicable law; or (v) disclosing or discussing sexual harassment or sexual assault disputes, or any other unlawful or unsafe Company conduct or practices. Nothing in this General Release requires Executive to obtain prior authorization before engaging in any conduct described in the previous sentence or to notify any Released Party that Executive engaged in any such conduct.

2. Acceptance of this General Release; Consideration Period for Waiver of ADEA Rights. Executive understands that Executive may take 21 calendar days from the date this General Release is presented to Executive to consider whether to sign and accept this General Release, subject to the additional terms and conditions in Section 4 below. For Executive’s acceptance to be effective, Executive shall return Executive’s signed General Release to the Company so that it is received by the Company at 100 W Airport Road, Stillwater, Oklahoma 74075, Attn: Chief Legal Officer, Email: Valerie.jacob@usare.com. By signing this General Release, Executive acknowledges and agrees that Executive has been advised of and understands the following: (a) Executive has carefully read and fully understands all terms and conditions of this General Release; (b) Executive is receiving valid consideration for this General Release that is in addition to anything of value to which Executive is already entitled; (c) this General Release does not waive rights or claims that may arise after it is executed; (d) by signing this General Release, Executive is waiving and releasing rights and claims under the ADEA (as amended by the OWBPA); (e) Executive has been given the opportunity to consult with an attorney of Executive’s choice before signing this General Release; (f) Executive will be provided 21 calendar days following Executive’s receipt of this General Release to consider this General Release before accepting it (the “Consideration Period”), or Executive has freely and knowingly waived the right to consider this General Release for the full Consideration Period by executing the General Release before the expiration of the Consideration Period. Changes to this General Release, whether material or immaterial, do not restart the Consideration Period.

3. No Admission of Wrongdoing. Executive acknowledges that neither this General Release, nor the furnishing of the consideration for this General Release, shall be deemed or construed at any time to be an admission by any Released Party of any improper or unlawful conduct.

4. Effectiveness and Revocation of this General Release. Executive shall have an additional seven calendar days after signing and agreeing this General Release to revoke it (the “Revocation Period”). Executive may revoke Executive’s acceptance of this General Release by delivering a written statement during the Revocation Period to the Company’s Chief Legal Officer and Head of Human Resources, Email: legal@usare.com and hr@usarare.com, which clearly and unequivocally states that Executive is revoking Executive’s acceptance of this General Release and does not want to be bound by it. This General Release shall not become effective until 12:01 AM Central Standard Time on the eighth calendar day after the date on which Executive executes (and does not revoke) this General Release. If a notice of revocation is not received prior to the expiration of the Revocation Period, this General Release will take effect and will become irrevocable and binding.

(a) Executive acknowledges that Executive’s entry into this General Release (and non-revocation thereof) is a condition to Executive’s receipt of the consideration set forth in Section 3 of the Retirement Agreement, and that, in the absence of timely executing, returning, and not revoking this General Release and complying with its terms, Executive would not be entitled to receive such consideration (or any portion thereof).

Exhibit 10.2

EXECUTIVE CHAIR AGREEMENT

This Executive Chair Agreement (this “Agreement”) is entered into on July 19, 2026 (the “Effective Date”) by and between Michael Blitzer (the “Executive Chair”) and USA Rare Earth, Inc., a Delaware corporation (the “Company”) (collectively referred to as the “parties” or individually referred to as a “party”).

RECITALS

WHEREAS, the Executive Chair is presently serving in the capacity of non-employee director and Chairman on the Company’s Board of Directors (the “Board”);

WHEREAS, effective as of the Effective Date, the Company and the Executive Chair mutually desire for the Executive Chair, and the Board is hereby appointing the Executive Chair, to serve in the capacity of Executive Chair on the Board;

WHEREAS, the Executive Chair’s appointment as Executive Chair is in addition to his current service as a member of the Board; and

WHEREAS, on and following the Effective Date, the Executive Chair shall be eligible to receive the compensation provided pursuant to this Agreement in connection with the Executive Chair’s services hereunder.

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

1. Duties and Effort. The Company requires that the Executive Chair perform the duties customarily related to this function, including (a) advising the Company’s senior management, including the Chief Executive Officer of the Company, on matters of Company operations, (b) supporting the Company’s long-term corporate strategy and major capital allocation decisions, (c) assisting with strategic partnerships, government relations and key customer relationships, particularly in the United States, (d) supporting investor and capital markets engagement, (e) providing guidance and advising on acquisitions, financings and other strategic transactions, and (f) serving as a thought partner to management on key business initiatives, while remaining removed from day-to-day operational decision-making. In addition, the Executive Chair is required to continue to perform the duties required of him as non-employee director and Chairman of the Board, including (1) acting as Chair of the Board and stockholder meetings, (2) leading the Board and setting the Board’s agendas in coordination with senior management, (3) acting as liaison between the Company’s senior management and the Board and its committees, (4) as well as other customary duties as may be determined and assigned by the Board and as may be required by the Company’s governing instruments. The Executive Chair agrees to devote such time as is reasonably and customarily necessary to perform completely these duties to the Company, although the parties recognize that this is not expected to occupy the Executive Chair’s full business time and attention. The Executive Chair acknowledges that the Board may appoint a Lead Independent Director pursuant to its Corporate Governance Guidelines.

2. Term. The term of this Agreement shall commence as of the Effective Date and shall continue until the earliest of (a) appointment of a successor Board leader (not including the Lead Independent Director), (b) the date of the Company’s next annual general meeting of stockholders (“Annual Meeting”), or (c) upon his earlier death, incapacity, removal or resignation. Notwithstanding (b) in the foregoing, if the Executive Chair is validly elected by the Company’s stockholders as a director and reappointed by the Board as Executive Chair of the Board, the term will automatically renew until the next Annual Meeting, subject to (a) and (c) of the foregoing. The foregoing sentence shall apply with respect to the 2028 Annual Meeting with the intention that this Agreement shall remain in effect until the 2029 Annual Meeting, subject to (c) of this Section 2 (the “Term”). For the avoidance of doubt, the termination of this Agreement alone shall have no effect on the Executive Chair’s appointment as non-employee director on the Board and, if applicable, Chairman of the Board, and if the Board appoints a successor Board leader or the Board does not reappoint him as Executive Chair of the Board at the 2027 or 2028 Annual Meeting (other than as a result of the Executive Chair’s voluntary decision not to be so appointed), then the resulting termination of his Executive Chair role would be considered a termination without Cause for all purposes, including the awards granted pursuant to Section 4. If the Agreement remains in effect through the 2029 Annual Meeting and the parties do not extend the Agreement, the expiration of the Term on the 2029 Annual Meeting shall be considered a termination without Cause for all purposes, including the Awards granted pursuant to Section 4. During the Term, the Company will exercise commercially reasonable efforts to cause the Executive Chair to be nominated for election to the Board on an annual basis.

3. No Employment Relationship. This Agreement is not intended to create an employment relationship between the parties. Rather, it is the parties’ intention that the Executive Chair shall be an independent contractor of the Company. The Executive Chair shall be solely responsible for the payment or withholding of all federal, state, or local income taxes, social security taxes, unemployment taxes, and any and all other taxes relating to the compensation he earns under this Agreement. The Executive Chair shall not be eligible to participate in any of the Company’s employee benefit plans.

4. Compensation. For services to be rendered in his capacity as Executive Chair and non-employee director of the Board, the Company agrees to pay the Executive Chair the compensation set out below.

5. Expenses. The Executive Chair shall be entitled to receive reimbursement for all reasonable, documented business expenses incurred by the Executive Chair in performing services hereunder, in accordance with the policies and procedures then in effect and established by the Company.

6. Restrictive Covenants.

7. Termination. The Board and the Executive Chair may each terminate this Agreement with or without notice. Nothing contained herein or omitted herefrom shall prevent the Board or stockholders of the Company from removing the Executive Chair as permitted under the Company’s certificate of incorporation, bylaws and its Corporate Governance Guidelines, each as amended or modified from time to time, and by applicable law, rule or regulation, including, without limitation, the DGCL.

8. Indemnification. To the fullest extent permitted by applicable law and as provided in the Company’s bylaws, during the Term and for such period thereafter as may be necessary to continue to indemnify the Executive Chair for the Executive Chair’s acts while a director or Executive Chair of the Company in accordance with this Section 8, the Company agrees to defend and indemnify the Executive Chair against and to hold the Executive Chair harmless from any and all claims and liabilities expenses (but excluding disputes arising under this Agreement, and claims asserted by the Company, the Board, of any of the Company’s affiliates) asserted against the Executive Chair for actions taken or omitted to be taken by the Executive Chair in good faith and within the scope of the Executive Chair’s responsibilities as a director, officer or Executive Chair of the Company and its affiliates during the term of this Agreement. The Company shall cause the Executive Chair to be provided coverage under any D&O liability insurance policies that are maintained by the Company from time to time in the same manner as other executive officers and directors of the Company are covered.

9. Third-Party Agreements and Rights.

The Company will consult with the Executive Chair in good faith regarding the implementation of the provisions of this Section, provided that the Company will not have any liability to the Executive Chair with respect of the same.

USA Rare Earth Announces Leadership Transition

Barbara Humpton to retire and Thras Moraitis to become CEO, both effective October 1, 2026

Michael Blitzer elected Executive Chairman, effective immediately

STILLWATER, Okla., July 20, 2026 — USA Rare Earth, Inc. (Nasdaq: USAR) (“USAR”, “USA Rare Earth”, or the “Company”), announced today that Barbara Humpton will retire as Chief Executive Officer and Board Director on October 1, 2026. USAR’s Board of Directors has named Thras Moraitis, current CEO of the Serra Verde Group (“Serra Verde”) and a highly experienced operator in the rare earths industry, as Ms. Humpton’s successor. Mr. Moraitis will assume the CEO role on October 1, 2026, following the anticipated completion of USAR’s combination with Serra Verde by the end of August. During the interim period, Mr. Moraitis will continue to oversee the combined company’s operations as President.

Michael Blitzer, current Chairman of USAR’s Board and significant shareholder in the Company, has been elected Executive Chairman, effective immediately. Since its public listing, he has played a central role in setting USAR’s strategic direction, anchoring its vision to build a global mine-to-magnet value chain and identifying organic and inorganic growth opportunities. He also helped lead USAR’s efforts to obtain U.S. government financing, including by personally agreeing to restrictions on the transfer of his USAR common stock until certain strategic funding release milestones under the government financing are satisfied.

Ms. Humpton has been instrumental in steering USAR’s mine-to-magnet strategy, overseeing company milestones that have fundamentally transformed the Western critical minerals landscape. Under her leadership, USAR secured landmark public-private partnerships and established a global footprint spanning critical processing, metals, and magnet capabilities. She has also helped establish a culture that attracts the best and brightest minds across the sector.

Mr. Moraitis has served as Chief Executive Officer of Serra Verde since January 2023 and has an unparalleled track record of operational execution, strategic development and transaction leadership in the rare earths sector. Over his tenure, Serra Verde transformed into the only large-scale producer of the four critical magnetic rare earths outside of Asia and a pioneer of the Brazilian rare earths sector. In April 2026, Serra Verde entered into a definitive agreement to combine with USAR, creating a platform to support the first fully integrated, Western mine-to-magnet supply chain. Prior to Serra Verde, Mr. Moraitis served on the Executive Committee of Xstrata, led by CEO Sir Mick Davis, where he and the team grew Xstrata into a US$65B company, ultimately selling it to Glencore in 2013.

“On behalf of the Board of Directors, I want to thank Barbara for her leadership and contributions to USA Rare Earth – including securing landmark public-private agreements, advancing our global mine-to-magnet strategy and building an exceptional portfolio of industry leading assets,” said Michael Blitzer, Executive Chairman of USA Rare Earth’s Board of Directors. “With the Serra Verde combination nearing completion and our overall focus shifting to execution, Barbara and the Board agree this is the right time for a leadership transition. Thras is among a rare group of leaders in this industry, with a proven record of carrying companies through integration and large-scale project execution, honed over his many years helping build Xstrata. He knows what it takes to build an industry champion, and his relentless focus on operational excellence will be invaluable as we ramp to full production and scale. We are confident Thras is the right leader to guide USAR through this pivotal next chapter and deliver lasting value for all our stakeholders.”

“When I joined USAR, I said this work was about being part of a mission that matters: strengthening national security, advancing American industrial competitiveness and building the critical supply chains required for the future,” said Ms. Humpton. “With the close of the Serra Verde transaction approaching and focus shifting to execution, the Board and I agree this is the right time to pass the torch to Thras. I could not be more grateful to the USAR team for what we have built, and the Board and our partners for their collaboration and commitment to those efforts. I look forward to supporting Thras and the team, and watching them execute on the transformative work that lies ahead.”

Mr. Moraitis concluded, “I am honored and excited to take on this role and grateful to Barbara for the strong foundation she has built. Over the past year, under Barbara’s leadership, the company has been transformed into a leading rare earth platform with enormous potential for growth. Through the merger integration preparation, I have become deeply familiar with USAR’s operations across all steps in the value chain, its mission-critical ambitions and the importance of what it is building. Mike, the Board and I are all closely aligned in our vision for USAR: to create a platform comprising all components of the rare earth value chain, with the scale and capabilities to lead this industry globally. The rare earth industry and our customers are facing the unprecedented challenge of building secure, integrated supply chains to power the vital technologies propelling our society forward. Together, with our team and partners around the world, we will rise to this challenge.”

Additional Details About Thras Moraitis

Prior to joining Serra Verde in 2023, Mr. Moraitis served as Chief Development Officer and a member of the Executive Board of EuroChem Group AG. Mr. Moraitis was also a co-founder of X2 Resources, a US$5.6B mining investment fund. He previously served as Group Head of Strategy and Corporate Affairs and as a member of the Executive Committee of Xstrata Plc, where he was responsible for strategic development, post-acquisition integration, leadership development, external affairs and investor relations as well as Xstrata’s technology business. He has been involved in approximately 40 transactions over the course of his career and currently serves as an advisor to Vision Blue Resources. Mr. Moraitis holds an honors BSc in Electrical Engineering, a postgraduate qualification in Computer Science and an MBA.

Exhibit 99.2

Subject Line: Leadership Update

Team,

This morning we announced some important news about USA Rare Earth’s leadership, and I am writing to make sure you hear directly from me. As you can read in this press release, I will be retiring as Chief Executive Officer, effective October 1, 2026. I am excited to let you know that Thras Moraitis, current CEO of Serra Verde, will be taking over as CEO of the Company at that time. This transition of leadership will follow the anticipated completion of our combination with Serra Verde, which we expect to close by the end of August. I look forward to working closely with Thras, the Board and the leadership team over the next couple of months to ensure we execute a seamless transition.

From the moment I assumed the CEO role here at USAR, I have been energized by the opportunity to lead work of real consequence. Rare earths are incredibly important for ensuring American national security and economic competitiveness, and it has been my honor to work with this exceptional team to meaningfully advance those efforts.

Our mine-to-magnet strategy has rapidly moved from concept to execution and we have expanded our global footprint across critical processing, metals and magnet capabilities, furthering the readiness and continued buildout of our domestic infrastructure. In a complex sector like this one, each milestone achieved is an essential part of a larger vision. Our collective efforts have been validated in a number of ways, including through the landmark public-private partnership we announced in June with the U.S. Government for up to $1.6 billion, representing the largest of its kind in our industry.

Staying true to that larger vision, our focus is now on the next step: integration, continued operational execution, production scale-up and delivery against key milestones. Thras is a leader who holds deep operating experience and global mining expertise. You might recall hearing from Thras when we first announced the transaction in April. Over the last several months, Thras has developed a strong understanding of USAR’s assets, talent, and the breadth of opportunities that lie ahead for our organization. I am confident he is the right next leader for USAR, and that you will enjoy working with him.

Effective today and as we start working through this transition process, our Board Chairman, Mike Blitzer, has been elected Executive Chairman. Mike has been, and will continue to be, instrumental in shaping our strategy, and he will continue working closely with the company’s executive leadership team to oversee the buildout of our platform.

There is real alignment around the consistent objective to build USA Rare Earth into the rare earths leader for the benefit of the United States and its allies. For our team members, I want to emphasize that this transition does not change the mission that you are helping to advance every day. It is business as usual for us, and critical that we all stay focused on pushing USA Rare Earth forward.

This has been an incredible chapter and I deeply appreciate all of you for your hard work, partnership and camaraderie. I look forward to closing out our time together on a high note, and to supporting Thras and all of you as USA Rare Earth continues executing on the transformative work ahead.

Sincerely,

Barbara

These statements include statements regarding USAR’s expectations for future development, operations, strategies, transactions and financial performance. Such statements can be identified by the fact that they do not relate strictly to historical or current facts. Words such as “anticipate,” “can,” “continue,” “could,” “growth,” “may,” “might,” “plan,” “potential,” “project,” “propose,” “should,” “target,” “vision,” “will,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

Forward-looking statements are subject to risks and uncertainties and potentially inaccurate assumptions that could cause actual results to differ materially from our expectations, including without limitation: risks that the proposed transactions with Serra Verde Group, Carester SAS and Texas Mineral Resources Corp. may not be consummated on their anticipated timelines or at all; we may not realize the anticipated benefits of our proposed and prior acquisitions, including expected synergies, financial performance, estimated earnings before interest, taxes, depreciation and amortization and, in the case of Serra Verde, integration of operations, on the anticipated timeline or at all; the ability of our magnet manufacturing facility in Stillwater, Oklahoma (the “Stillwater facility”) or other future magnet manufacturing facilities to commence commercial operations on the timing and with the production capacity anticipated or at all; our limited operating history; our ability to commercially extract minerals from the Round Top deposit in Texas on our anticipated timeline or at all; risks that we may experience delays, unforeseen expenses, increased capital costs, and other complications in operating our business; our ability to raise necessary capital on acceptable terms or at all; potential dilution to existing stockholders and adverse effect on our stock price if we issue additional common stock or equity-linked securities; the volatility of our stock price; our ability to satisfy project milestones and other conditions to disbursement under our financing arrangement with the DOC on the anticipated timeline or at all; our dependence on continued governmental support for the DOC financing transactions, which remains subject to changes in laws, regulations, administrations and appropriations; extensive affirmative and negative covenants, domestic content and national security guardrail provisions and ongoing reporting obligations in the DOC financing agreements that restrict our operational and financial flexibility; the risk that defaults under the DOC funding agreements could trigger cross-defaults across our financing arrangements; the impact of the DOC’s equity interest in us on our ability to pursue strategic transactions and on our relationships with customers, suppliers, partners and other counterparties; the availability of rare earth oxide, metal feedstock and other materials, utilities (including power and water) and equipment in quantities and prices that allow us to develop and commercially operate our Stillwater facility and other facilities; our ability to meet individual customer specifications and manufacture a consistently high quality product; fluctuations in demand for and prices of our products, including without limitation as a result of dumping, predatory pricing and other tactics by our competitors or state actors or the overall competitive environment; our ability to achieve positive cash flow or profitability or the ability to access cash flow within our corporate structure due to restrictions contained in our financing agreements; our ability to convert current commercial discussions and/or memorandums of understanding with customers for the sale of our neo magnets and other products into definitive orders; geopolitical developments or disruptions, such as changes in the political environment, export/import or environmental policy of the People’s Republic of China, the United States or other countries in which we operate or sell products or otherwise; limitations imposed on our business by the Chinese government; war, terrorism, natural disasters or public health emergencies; our ability to retain or recruit key personnel; environmental, health and safety regulations; and our ability to comply with requirements for federal, state and local government incentives and financing.

Additional risks and detailed information regarding factors that may cause actual results to differ materially has been and will be included in our filings with the SEC.

Exhibit 99.3

Subject Line: USA Rare Earth’s Next Chapter

Dear future colleagues,

Following Barbara’s note to the team earlier today, I wanted to reach out to introduce myself; to thank Barbara for what she has brought to the company; and to express my excitement at the opportunity we have to write the next chapter of the company’s story. I have had the chance to meet some of you in person and on our various integration calls, and others will have seen my name following the announcement of the Serra Verde transaction.

I grew up in South Africa – a country with a storied mining history – and my whole career has been shaped by the global minerals and metals industry. I began as a young engineer in the South African deep-level gold mines, following which I was part of a small team which invented the microchip-based detonator, still widely in use in mining globally. Early on in my career I was fortunate to work with wonderfully generous mentors, who nudged me towards the strategic and operational side of the business. One of those is Sir Mick Davis, who will also join USAR’s Board, and I was privileged to join the team he led, which grew Xstrata Plc from a $500M business into a $65B multinational mining and metals major. This was a decade-long ride of sheer excitement and extraordinary outcomes, fueled by our conviction about a once-in-a-generation industrialization of China.

Based on a similar conviction about the future demand for rare earths, and a burning desire to make a difference by working with exceptional people to provide the vital elements for critical technologies that will underpin the development of our society, I joined Serra Verde in 2023. Since then, our team has steered it into the only scaled producer of all four magnetic earths outside Asia, establishing its position as a strategic asset in the new, emerging value chains.

The next step in Serra Verde’s strategy was to leverage our first-mover advantage to integrate downstream through to magnets, thereby ensuring our rare earth elements reach their end-use markets securely and reliably. It was in that context that I met Mike Blitzer and Barbara – who were pursuing the identical strategy in the opposite direction – up the value chain. There was an immediate meeting of minds, and a belief that combining USA Rare Earth and Serra Verde would accelerate the creation of the first truly integrated player from mine to magnet and beyond.

Having spent significant time with USA Rare Earth over the last few months, I have seen firsthand the strength of your world-class assets and the highly capable teams advancing them. The speed with which you have put the company on the international map from a humble start is breathtaking. Following completion of the transaction, the combined company will be positioned to capture boundless opportunity in this critical emerging industry; not only supplying the materials to create our future world but also enabling the development of many global industries whose ambitions are otherwise constrained by a lack of reliable supply.

This is a pivotal moment for USA Rare Earth’s platform. My and Barbara’s top priority is ensuring this transition is as seamless as possible. We must enter a period of thoughtful integration and focused execution, and Barbara and I will work in tandem to ensure a smooth transition. This hand-off is a testament to our shared dedication to USAR’s mission.

I am deeply grateful for Barbara’s partnership and the strong foundation she has built, leaving a lasting impact both on this company and the overall industry. She has elevated the Company’s global profile and secured the investments that have enabled a series of monumental acquisitions and growth initiatives.

My intention is to continue that momentum. Our immediate focus will be on integrating the assets that have been acquired, specifically bringing Serra Verde and the Pela Ema mine’s capabilities into USA Rare Earth’s fold, and unlocking the potential of another strategic asset, LCM. At the same time, we need to continue scaling operationally to meet our commitments and milestones across our value chain. It is wonderful to have the opportunity once more to work with exceptional teams to build a company of global scale and deliver long-term growth in value, while transforming an entire industry in support of our society’s technological evolution.

Rare earths sit at the center of the vital technologies and supply chains that will define the decades to come, including renewable energy, semiconductors, medical devices, defense systems and new forms of transportation. Few companies anywhere are as well positioned to lead as this one. That is a responsibility I don’t take lightly, and it is one I am energized to take on alongside all of you. I look forward to meeting many more of you in the coming weeks, hearing your ideas, and getting to work on what lies ahead together.

Sincerely,

Thras
