STILLWATER, Okla., Aug. 24, 2026 (GLOBE NEWSWIRE) -- USA Rare Earth, Inc. (NASDAQ:USAR) ("USAR," "USA Rare Earth," or the "Company") today announced the special purpose vehicle (the "SPV") that will purchase 100% of the Phase 1 production of rare earth materials ("the Offtake Agreement") produced by Serra Verde Group ("Serra Verde") has completed its capitalization arrangements.

Pursuant to the capitalization transaction, totaling an upsized $1.55 billion in funding:

The Department of War has committed to a $750 million investment in the SPV - $250 million more than the $500 million originally contemplated under the Offtake Agreement. The agreement, which has both a take-or-pay arrangement and floor prices, is vital to support the development of an integrated rare earth value chain.
The SPV has secured a commitment letter from a Tier-1 institutional bank for a senior secured borrowing-base revolving credit facility (the "Senior Debt Facility") in an aggregate principal amount of up to $500 million, subject to certain conditions precedent set forth therein. The Senior Debt Facility is intended to fund working capital for the SPV’s purchases of rare earth products from SV Management Switzerland.
The U.S. government has entered into a forward purchase contract with the SPV for the purchase of not less than $300 million of rare earth payable products over five years.

USA Rare Earth announced a definitive agreement to acquire Serra Verde on April 20, 2026. On the same day, Serra Verde announced it entered into a 15-year offtake agreement to supply the SPV capitalized by various U.S. Government agencies, as well as private capital sources for 100% of its Phase I production with guaranteed price floors for its magnetic rare earths, including the industry’s first and only price floors for heavy rare earths dysprosium and terbium. The capitalization satisfies one of the closing conditions for USAR’s proposed merger with Serra Verde. Additional information regarding the Offtake Agreement, the Offtake Amendment and the capitalization of the SPV is contained in USAR’s Current Report on Form 8-K filed with the SEC.

"We appreciate the strategic support and upsized funding commitment of the U.S. government and are proud to continue our strong partnership to build a secure and resilient rare earth supply chain," said Michael Blitzer, Executive Chairman of USA Rare Earth. "With more than $1 billion already invested, Serra Verde is one of the world’s most advanced rare earth projects and the only commercial producer of all four magnetic rare earths outside Asia. Serra Verde can now begin supplying these critical materials into the U.S. market and is positioned to be the first to deliver all four into Western supply chains at scale. With the SPV capitalized, we expect to close the Serra Verde acquisition in the coming days, providing access to advanced processing technologies and integrating a foundational asset into USA Rare Earth’s mine-to-magnet platform."

Following close, USA Rare Earth will own the Pela Ema mine in Goiás, Brazil, the only ionic clay rare earth mine in commercial production outside of Asia and will operate an integrated rare earth value chain from mine to magnet across the United States, the United Kingdom and Brazil. Rare earth magnets are the building blocks of the technologies powering today’s economy, from mobility and electrification to robotics and data centers, to the aerospace and defense platforms that safeguard national security, to the energy and medical technologies improving lives around the world. The transaction will also give Serra Verde access to emergent rare earth processing technologies, deepening the integration of the two companies’ combined value chain. To date, more than $1 billion has been invested in Serra Verde.

In connection with the transactions contemplated by the Merger Agreement, on July 24, 2026, USAR filed a Proxy Statement with the SEC for its special meeting of stockholders to be held on August 28, 2026 at 10:00 a.m. Eastern Time to consider certain proposals related to the merger as further described in the Proxy Statement. The Company expects the transaction to close promptly following the special meeting and the satisfaction or waiver of the remaining closing conditions.

These statements include those relating to the Offtake Amendment, the proposed acquisition of Serra Verde, the satisfaction of the remaining conditions to the completion of the merger, the capitalization of the SPV and the U.S. government financial support therefor, the documentation, closing and funding of the Senior Debt Facility and the continued effectiveness of the Offtake Agreement. Such statements can be identified by the fact that they do not relate strictly to historical or current facts. Words such as "aim," "anticipate," "believe," "can," "continue," "could," "estimate," "expect," "growth," "intend," "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 merger may not be consummated on its anticipated timeline or at all, including as a result of the failure to obtain the USAR stockholder approval or to satisfy the other conditions to closing; risks that the proposed transaction with Carester SAS may not be consummated on its anticipated timeline or at all; risks that the Senior Debt Facility is not documented, closed or funded, in whole or in part, and that the SPV is otherwise inadequately capitalized and unable to perform its obligations under the Offtake Agreement; risks that the forward purchase contracts between the U.S. government and the SPV may not result in purchases at the levels or on the timeline currently anticipated; risks that the U.S. government financial support described herein may be reduced, delayed or withdrawn as a result of changes in government policy, budgetary constraints or political developments; risks that the remaining conditions precedent under the Offtake Agreement are not satisfied or waived by the applicable long-stop date, or that the Offtake Agreement is terminated or ceases to be in full force and effect; risks that, because the requirement with respect to the Senior Debt Facility under the Offtake Agreement, as revised by the Offtake Amendment, may be satisfied by entry into a commitment letter rather than by a funded facility, USAR and Middlebury Merger Sub Ltd., an indirect, wholly owned subsidiary of USAR ("Merger Sub"), become obligated to complete the merger notwithstanding the absence of funded debt financing at the SPV; risks that we may not realize the anticipated benefits of the merger or 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; political, economic, regulatory, tax, currency and other risks associated with Serra Verde’s operations in Brazil and Switzerland following the consummation of the Serra Verde acquisition; the assumption of substantial indebtedness under Serra Verde’s Retained Finance Agreement, which contains restrictive covenants and other requirements that could adversely affect the combined company’s financial flexibility and operations; the risk that the planned CEO transition is contingent on the timely closing of the Serra Verde acquisition and that any delay or failure of this acquisition to close could result in leadership uncertainty and may require the board of directors of USAR to identify an alternative CEO successor; the ability of our Stillwater magnet manufacturing facility to generate revenue and the ability of our planned Blacksburg facility 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 on our anticipated timeline or at all; risks that we may experience delays, unforeseen expenses, increased capital costs, and other complications while developing our projects; 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; 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 produce a consistently high quality product; fluctuations in demand for and prices of neo magnets and our other 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; our dependence, in part, on the growth of existing and emerging uses for neo magnets; the risk that additional manufacturing, refining and mining competitors could result in a reduction in revenue; 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; our designation on an export control list by China which has had and is expected to continue to have an adverse impact on our ability to source key raw materials and supplies from China; war, terrorism, natural disasters or public health emergencies; our ability to retain or recruit key personnel; environmental, health and safety regulations; the receipt of funding from the U.S. Department of Commerce is subject to the achievement of milestones which may not be achieved on the expected timeline or at all;
