“With the downstream capabilities of our magnet manufacturing plant in Stillwater well underway, which is now complimented by the metal making and strip casting capabilities of LCM, we are closing the loop within the rare earth magnet supply chain. We are also progressing toward pilot scale testing of our swarf recycling flow sheet and are moving into the Pre-Feasibility Study phase for Round Top, which are both exciting developments. Our strategy all along has been to take the steps necessary to secure the supply chain with the critical know-how and capabilities from mine all the way through magnet manufacturing. This progress across our business and the acquisition of LCM represent milestone achievements in the execution of this strategy,” said Barbara Humpton, USAR Chief Executive Officer.

Ms. Humpton continued, “The increased focus on critical rare earths, and their importance to every aspect of our economy, only reinforces what we are building: a fully integrated U.S.-based rare earth material and magnet platform that supports national priorities, supply-chain stability for the U.S. and our allies, while also delivering long-term value creation for our shareholders. Our job is the disciplined execution of this plan, and we will continue to execute and build on our progress in the quarters ahead.”

Detailed information regarding factors that may cause actual results to differ materially has been and will be included in the Company’s periodic filings with the SEC, including the Company’s Form 10-K that the Company filed with the SEC on March 31, 2025 and the Company’s latest Quarterly Reports on Form 10-Q filed with the SEC.

This press release includes certain non-GAAP financial measures, including adjusted net loss attributable to USA Rare Earth, Inc., and adjusted net loss per share attributable to USA Rare Earth, Inc. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles in the United States of America, or GAAP. These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions, and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies. As such, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP.

The Company believes these non-GAAP measures of financial results provide useful supplemental information to management and investors regarding certain financial and business trends related to the Company’s financial condition and results of operations, and as a supplemental tool for investors to use in evaluating its ongoing operating results and trends and in comparing its financial measures with other companies that present similar non-GAAP financial measures. The Company uses these non-GAAP financial measures to analyze its operating performance and future prospects, develop internal budgets and financial goals, and to facilitate period-to-period comparisons. The Company believes these non-GAAP financial measures reflect an additional way of viewing aspects of its operations that, when viewed with its GAAP results, provide a more complete understanding of factors and trends affecting its business. Current and prospective investors should review the Company’s audited annual and unaudited interim financial statements, which are filed with the U.S. Securities and Exchange Commission, and not rely on any single financial measure to evaluate our business.

•Adjusted net loss attributable to USA Rare Earth, Inc. is a non-GAAP financial measure that the Company defines as net loss attributable to USA Rare Earth, Inc. which excludes (loss) gain on fair market value of financial instruments.

•Adjusted net loss per share attributable to USA Rare Earth, Inc. - Diluted is a non-GAAP financial measure that the Company defines as net loss attributable to USA Rare Earth, Inc. adjusted for declared and deemed dividends, interest accretion, and (loss) gain on fair market value of financial instruments, divided by weighted average diluted shares outstanding.
