Item 1.01. Entry into a Material Definitive Agreement.
Agreement and Plan of Merger
On March 4, 2026, USA Rare Earth, Inc. (“USAR”) entered into a definitive Agreement and Plan of Merger (the “Merger Agreement”) by and among USAR, Texas Mineral Resources Corp., a Delaware corporation (“TMRC”), Hamer Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of USAR (“First Merger Sub”) and Hamer Merger Sub, LLC, a Delaware limited liability company and a wholly owned subsidiary of USAR (“Second Merger Sub” and together with First Merger Sub, the “Merger Subs”). The Merger Agreement provides for the merger of First Merger Sub with and into TMRC, with TMRC surviving the merger as a wholly owned subsidiary of USAR (the “First Merger”) at the effective time of the First Merger (the “Effective Time”). Promptly following the Effective Time, the Merger Agreement also contemplates a second merger of Second Merger Sub with and into the surviving corporation in the First Merger, with Second Merger Sub surviving the second merger as a wholly owned subsidiary of USAR (the “Second Merger” and together with the First Merger, the “Mergers”). The Transactions (as defined below) are expected to be consummated no later than the third calendar quarter of 2026, subject to the satisfaction or waiver of the conditions precedent to such closing.
The board of directors of each of USAR and TMRC have approved the Merger Agreement, the Mergers and the other transactions contemplated thereby (collectively, the “Transactions”).
Merger Consideration
Subject to the terms and conditions set forth in the Merger Agreement, at the Effective Time, each share of common stock, par value $0.01 per share, of TMRC (“TMRC Shares”) issued and outstanding immediately prior to the Effective Time (excluding any TMRC Shares as to which dissenters’ rights have been properly exercised and TMRC Shares owned by USAR, TMRC or any of their respective direct or indirect wholly owned subsidiaries) will automatically be converted into the right to receive that portion of a validly issued, fully paid and nonassessable share of common stock, par value $0.0001 per share, of USAR (a “USAR Share”) equal to the quotient obtained by dividing (a) 3,823,328 by (b) the aggregate number of TMRC Shares outstanding on a fully diluted basis at the Effective Time. Holders of TMRC Shares who are otherwise entitled to a fractional USAR Share will receive cash in lieu of such fractional share.
Conditions to the Mergers
The completion of the proposed Transaction is subject to the satisfaction or waiver (where permitted) of certain conditions, including (i) the adoption of the Merger Agreement by the affirmative vote of the holders of a majority of all outstanding TMRC Shares entitled to vote thereon (the “Requisite TMRC Vote”); (ii) the authorization for listing the USAR Shares to be issued as merger consideration on the Nasdaq Global Market if required under its rules and regulations; (iii) the absence of any law or order that makes illegal, enjoins or otherwise prohibits the consummation of the proposed Transactions; and (iv) the effectiveness of a registration statement on Form S-4 in connection with the issuance of the USAR Shares as merger consideration in the First Merger, which will include a prospectus relating to the USAR Shares to be issued as merger consideration and a proxy statement relating to TMRC’s stockholder meeting to approve the proposed Transactions and the absence of any stop order or proceedings to that effect by the SEC. The obligation of each of USAR and TMRC to consummate the proposed Transactions is also conditioned on, among other things, the truth and correctness of the representations and warranties made by the other party as of the closing date (subject to certain “materiality” and “material adverse effect” qualifiers), the performance by the other party, in all material respects, of such other party’s covenants and agreements under the Merger Agreement, the absence of the occurrence of a material adverse effect with respect to the other party from the date of the Merger Agreement through the Effective Time.
1
Certain Other Terms of the Merger Agreement
The Merger Agreement contains customary representations and warranties made by each of USAR and TMRC, and also contains customary pre-closing covenants. Among other things, during the period after the date of the Merger Agreement to the Effective Time, each of USAR and TMRC have agreed to (i) use commercially reasonable efforts to conduct its business in the ordinary course and agreed to certain other operating covenants and to not take certain specified actions prior to the consummation of the Mergers subject to customary exceptions and (ii) use reasonable best efforts to take all actions necessary to consummate the Transactions. In addition, the Merger Agreement contains covenants that require TMRC to call and hold a stockholder meeting and, subject to certain exceptions, require the board of TMRC (“TMRC Board”) to recommend to its stockholders to approve the proposed Transactions and adopt the Merger Agreement.
The Merger Agreement prohibits TMRC from soliciting competing acquisition proposals, except that, subject to customary exceptions and limitations, prior to receiving the Requisite TMRC Vote, TMRC may provide information to, and negotiate with, a third party that makes an unsolicited acquisition proposal if the TMRC Board determines in good faith that such proposal constitutes, or would reasonably be expected to result in, a superior proposal with respect to an alternative transaction and failure to take such actions would be inconsistent with its fiduciary duties under applicable law.
The Merger Agreement provides for certain termination rights for each of USAR and TMRC, including, among others, (i) if the closing has not occurred by the date that is nine months from the date of the execution of the Merger Agreement, (ii) if the Requisite TMRC Vote has not been obtained at a stockholder meeting, (iii) if there is a final and non-appealable law or order preventing the consummation of the Mergers or (iv) the other party is in breach of the Merger Agreement in a manner that would result in a failure of an applicable closing condition (subject to the applicable cure period set forth in the Merger Agreement). Further, USAR may terminate the Merger Agreement if the TMRC Board makes an adverse recommendation change or if TMRC approves or enters into an alternative acquisition agreement. The Merger Agreement further provides that a termination fee equal to $3,250,000 will be payable by TMRC to USAR under certain specified circumstances, including a termination by USAR in the event of an adverse recommendation change by the TMRC Board.
The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 and incorporated herein by reference. A copy of the Merger Agreement has been included to provide USAR stockholders with information regarding its terms and is not intended to provide any factual information about USAR, TMRC, the Merger Subs or their respective affiliates. The representations, warranties and covenants contained in the Merger Agreement have been made solely for the purposes of the Merger Agreement and as of specific dates; were made solely for the benefit of the parties to the Merger Agreement; are not intended as statements of fact to be relied upon by USAR stockholders, but rather as a way of allocating the risk between the parties in the event the statements therein prove to be inaccurate; have been modified or qualified by certain confidential disclosures that were made between the parties in connection with the negotiation of the Merger Agreement, which disclosures are not reflected in the Merger Agreement itself; may no longer be true as of a given date; and may apply standards of materiality in a way that is different from what may be viewed as material by USAR stockholders. USAR stockholders are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties or their respective affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in USAR’s public disclosures. USAR acknowledges that, notwithstanding the inclusion of the foregoing cautionary statements, it is responsible for considering whether additional specific disclosures of material information regarding material contractual provisions are required to make the statements in this Form 8-K not misleading. The Merger Agreement should not be read alone but should instead be read in conjunction with the other information regarding the Merger Agreement, the Transactions, the parties, their respective affiliates and their respective businesses, that will be contained in, or incorporated by reference into, an information statement that USAR will file, as well as in the Forms 10-K, Forms 10-Q, Forms 8-K and other filings that USAR will make with the U.S. Securities and Exchange Commission (the “SEC”).

Voting and Support Agreements
In addition, in connection with the execution and delivery of the Merger Agreement, each director and officer of TMRC and certain of their affiliates (collectively, the “Supporting Stockholders”) have entered into a voting and support agreement (each, a “Voting and Support Agreement” and collectively, the “Voting and Support Agreements”) with USAR to, among other things, vote all TMRC Shares beneficially owned by such stockholders (A) in favor of (i) the adoption of the Merger Agreement and the consummation of the proposed Transactions, and (ii) any proposal to adjourn or postpone a stockholder meeting if there are not sufficient votes to obtain the Requisite TMRC Vote and (B) against (i) any alternative acquisition proposal, (ii) any change in the TMRC Board, (iii) any proposal or agreement made in opposition to or inconsistent with the Mergers or that could result in a breach of TMRC’s or the Supporting Stockholders’ obligations and (iv) any other action that is intended to or could impede, interfere with, prevent, delay, discourage, or frustrate the timely consummation of the Mergers, the other transactions contemplated by the Voting and Support Agreements, or TMRC’s, Merger Subs’ or USAR’s obligations or conditions under the Merger Agreement. The Supporting Stockholders are collectively the beneficial owners of approximately 19% of the outstanding TMRC Shares.
During the term of the Voting and Support Agreements, subject to certain customary exceptions, each Supporting Stockholder is subject to customary transfer and proxy restrictions and is prohibited from taking any action that could restrict its legal power and authority to vote.
The foregoing summary of the Voting and Support Agreements does not purport to be a complete description of all the parties’ rights and obligations under such agreements and is qualified in its entirety by reference to the full text of the Voting and Support Agreements, a form of which is filed as Exhibit 10.1 hereto and which are incorporated herein by reference.

Exhibit 99.1
USA Rare Earth to Acquire Texas Mineral Resources Corporation
Transaction Establishes USAR as Exclusive Operator of the Round Top Heavy Rare Earth and Critical Minerals Project
Round Top is North America’s Richest Known Deposit of Heavy Rare Earths and Critical Minerals
STILLWATER, OK, March 5, 2026 – USA Rare Earth, Inc. (Nasdaq: USAR) (“USAR”) and Texas Mineral Resources Corp. (OTCQB: TMRC) (“TMRC”) today announced a definitive agreement for USAR to acquire all of the outstanding shares of TMRC for 3,823,328 shares of USAR common stock.
The acquisition secures outstanding minority interests, establishing USAR as the sole operator and 100% economic beneficiary of the Round Top Project. This strategic transaction streamlines USAR’s operations as it builds a global champion in critical minerals and technology. USAR is developing the leading globally integrated mine to magnet platform, which is a U.S.-anchored, non-China value chain essential for the modern defense, robotics, energy, semiconductor and advanced manufacturing industries.
The implied total deal value is approximately $73 million, based on the closing price of USAR’s common stock on March 4, 2026, and provides TMRC stockholders with the benefits of USAR’s enhanced capital markets presence, liquidity and balance sheet.
Under its Accelerated Mining Plan (“AMP”), USAR is rapidly advancing the development of Round Top, with commercial production expected to begin in 2028. Acquiring TMRC’s 18.6% interest in the project – along with rights under existing long-term leases covering approximately 950 acres at Round Top and prospecting rights on an additional 9,345 acres – simplifies governance, unifies strategic decision-making, and aligns capital planning and execution under a single operator. Under the AMP, USAR expects that by 2030, it will extract from Round Top approximately 40,000 metric tons per day of rare earth and critical mineral feedstock.
Located on Texas state land, Round Top is a critical piece of USAR’s globally integrated non-China mine to magnet value chain, which will include rare earth oxide processing, metal making, and magnet manufacturing. It is operated under a long-term lease with the Texas General Land Office. Proceeds from the lease support the Texas Permanent School Fund and public education across the state.
In January 2026, USAR selected Fluor Corp., together with WSP Global Inc., as its Engineering, Procurement and Construction Management (EPCM) partners to advance the Definitive Feasibility Study and build-out of critical mining infrastructure, including water, processing support, and environmental systems.
“This acquisition secures a vital pillar in our strategy to build the world’s leading globally integrated, non-China critical mineral technology platform,” said Barbara Humpton, CEO of USAR. “We’re consolidating operational control of the Round Top project while ensuring long-term leasehold access for the adjacent land required to transition efficiently from development to commercial production. We appreciate the continued support of Texas General Land Office Commissioner, Dr. Dawn Buckingham, and her team for our development of a mine at Round Top. This acquisition strengthens our ability to execute our Accelerated Mining Plan by providing full access to the land required to help meet the strong and growing demand for heavy rare earths and critical minerals.”
“TMRC has long recognized the strategic importance of the Round Top deposit and its role in strengthening the domestic supply chain for heavy rare earths and critical minerals,” said Anthony Marchese, Chairman of TMRC. “We believe this transaction positions the project for successful commercial advancement while delivering meaningful value to TMRC stockholders without the potentially crippling dilution as a result of large cash calls. TMRC’s shareholders will now benefit from USAR’s three business segments that represent a true mine to magnets strategy as opposed to being invested solely in the development of the Round Top heavy rare earth project.”
Dr. Dawn Buckingham, Commissioner of the Texas General Land Office noted: “Round Top is one of the most strategically important mineral deposits in the United States, and it sits right here on Texas state land. This acquisition puts a well-capitalized, American-owned company in full control of developing the largest heavy rare earth deposit in the country. That means good-paying jobs for West Texans, critical royalty revenue for our Permanent School Fund, and a major step toward ending America’s dangerous dependence on China for the minerals that power our national defense. Texas is proud to be leading the way.”
The transaction has been approved by the boards of directors of both companies and is expected to close no later than the third calendar quarter of 2026, subject to the satisfaction of customary closing conditions, including approval of the stockholders of TMRC.
All directors and executive officers of TMRC have entered into voting support agreements with USAR pursuant to which they have agreed, subject to the terms of such agreements, to vote their shares of TMRC common stock in favor of the transaction.
Moelis & Company LLC acted as financial advisor and White & Case LLP acted as legal advisor for USAR. Roth Capital Partners LLC acted as financial advisor and Loeb & Loeb LLP acted as legal advisor to TMRC.
