USA Rare Earth, Inc. USAR is scheduled to release first-quarter 2026 results on May 13, after market close. The Zacks Consensus Estimate for earnings is pegged at a loss of 16 cents per share. The bottom-line projection indicates an increase of 15.8% from the year-ago number. USA Rare Earth reported a loss of 19 cents per share in the previous quarter. Image Source: Zacks Investment Research USAR’s earnings missed the Zacks Consensus Estimate in two of the trailing three quarters and surpassed the same in one quarter. The company has a trailing three-quarter negative earnings surprise of 112.2%, on average. Our proven model does not conclusively predict an earnings beat for USAR this time around. The combination of a positive Earnings ESP and a Zacks Rank #1 (Strong Buy), 2 (Buy) or 3 (Hold) increases the odds of an earnings beat, which is not the case here, as elaborated below. Earnings ESP: USAR has an Earnings ESP of 0.00% as both the Most Accurate Estimate and the Zacks Consensus Estimate are pegged at a loss of 16 cents per share. You can uncover the best stocks before they’re reported with our Earnings ESP Filter. Zacks Rank: USAR presently carries a Zacks Rank #4 (Sell). You can see the complete list of today’s Zacks #1 Rank stocks here. USA Rare Earth Inc. price-eps-surprise | USA Rare Earth Inc. Quote USA Rare Earth is progressing toward commercial production at its Stillwater magnet manufacturing facility in Oklahoma. The plant will manufacture Neodymium Iron Boron (NdFeB) magnets, which are widely used in defense, aviation, automotive and other high-growth industries. The Stillwater facility is poised to become one of the first large-scale NdFeB magnet production plants in the United States, strengthening domestic rare earth supply-chain capabilities and reducing reliance on imports. USA Rare Earth is installing key equipment, assembling Line 1a and completing final preparations at the Stillwater facility for commissioning in early 2026. It is worth noting that the company started hiring and training engineers and technicians to operate the facility. USA Rare Earth has also strengthened its balance sheet through PIPE financing and warrant exercises. In January 2026, the company completed a $1.5 billion PIPE financing, with proceeds earmarked for upgrades at its Stillwater facility, expansion of magnet finishing operations and completion of Line 1b. These initiatives are expected to raise total NdFeB magnet production capacity to nearly 1,200 metric tons. USAR completed the acquisition of Less Common Metals in November 2025, which will supply critical metal and alloy feedstock for the Stillwater plant. In December 2025, LCM partnered with Solvay and Arnold Magnetic Technologies Corp. (Arnold) to provide a stable and premium-quality source of rare-earth materials. This addition and continued progress across its development initiatives are expected to have been a tailwind to its performance during the first quarter. Also, in January 2026, USA Rare Earth signed a non-binding Letter of Intent (LOI) with the U.S. Department of Commerce and announced a collaboration with the U.S. Department of Energy (DOE). The Department of Commerce’s CHIPS Program has provided an LOI entailing $277 million in proposed federal funding and a $1.3 billion senior secured loan under the CHIPS Act, a total of $1.6 billion. However, since its inception, USA Rare Earth has remained in the exploration and research stages, incurring losses while yet to generate any revenues. Amid its project development phase, the company has been grappling with rising operational expenses, which are expected to have adversely impacted its margins and profitability in the first quarter. USAR’s research and development expenses increased over the past few quarters due to a rise in legal & consulting costs, higher headcount & recruiting fees and other costs. All these factors are anticipated to have led to a loss in the first quarter. Shares of the company have jumped 77.1% in the past six months, outperforming the S&P 500 composite and Zacks Mining - Miscellaneous industry’s growth of 11.8% and 39.2%, respectively. However, USAR has lagged other key industry players like Aura Minerals Inc. AUGO and NioCorp Developments Ltd. NB, which have surged 129% and increased 12.9%, respectively, over the said time frame. Image Source: Zacks Investment Research From a valuation standpoint, USA Rare Earth is trading at a forward price-to-earnings ratio of a negative 33.18X against the industry average of 15.87X. In comparison, Aura Minerals and NioCorp Developments are trading at 5.68X and negative 13.17X, respectively. Image Source: Zacks Investment Research USA Rare Earth is progressing toward commercial production at its Stillwater, OK magnet facility, with Line 1a assembled and commissioning targeted for early 2026. The company strengthened its balance sheet through PIPE financing and warrant exercises, raising cash above $400 million and completing a $1.5 billion PIPE in January 2026 to expand NdFeB magnet capacity to nearly 1,200 metric tons. The acquisition of Less Common Metals and partnerships with Solvay and Arnold Magnetic Technologies support critical feedstock supply and U.S. domestic rare-earth production. USAR also secured proposed CHIPS Act support totaling $1.6 billion. However, rising R&D, legal and hiring costs are expected to have weighed on first-quarter margins and profitability. The company continues to invest heavily to expand its production capacity, supported by favorable long-term growth prospects. Existing investors may benefit from the company’s strong long-term fundamentals. However, given its high operating costs and the expected loss in the quarter, prospective investors can wait for a better entry point. Want the latest recommendations from Zacks Investment Research?

CENTENNIAL, CO / ACCESS Newswire / January 12, 2026 / NioCorp Developments Ltd. ("NioCorp," "our," or the "Company") (NASDAQ:NB) today provided its preliminary unaudited financial results for the three- and six-month periods ended December 31, 2025. As of December 31, 2025, the Company had a record cash balance of $307 million following a period of significant derisking of the Elk Creek Critical Minerals Project (the "Project"). During the six-month period, the U.S. Department of Defense awarded Elk Creek Resources Corp. up to $10 million to support certain activities related to the Elk Creek Critical Minerals Project; NioCorp completed an infill drilling campaign for the Project; closed on the acquisition of scandium alloy manufacturing assets of FEA Materials LLC; completed land purchases necessary to secure ownership of all land needed for the Project; and entered into agreements with the U.S. Department of Defense and Lockheed Martin related to scandium-based technologies for potential defense applications. The Company's results for the three- and six-month periods ended December 31, 2025 are presented below. Certain information in the following discussion is presented on a Non-GAAP basis, including adjusted net loss and adjusted net loss per share. The Company reported a net loss of $0.8 million, or $0.02 per share, compared to a net loss of $0.5 million, or $0.01 per share, for the three months ended December 31, 2024. On an adjusted basis, the Company reported an adjusted net loss of $5.3 million, or $0.06 per share, compared to an adjusted net loss of $1.9 million, or $0.05 per share, for the prior-year period.ﾹ The Company reported a net loss of $43.4 million, or $0.44 per share, compared to a net loss of $2.5 million, or $0.06 per share, for the six months ended December 31, 2024. On an adjusted basis, the Company reported an adjusted net loss of $13.6 million, or $0.15 per share, compared to an adjusted net loss of $3.3 million, or $0.08 per share, for the prior-year period.ﾹ The net loss for the three months ended December 31, 2025 primarily reflects non-cash gains of approximately $5.9 million related to earnout shares and warrants classified as liabilities on the consolidated balance sheet, driven by a slight decrease in the closing price of the Company's common shares between September 30, 2025 and December 31, 2025. The net loss for the six months ended December 31, 2025 primarily reflects non-cash losses of approximately $26.1 million related to earnout shares and warrants classified as liabilities on the consolidated balance sheet, driven by appreciation of the Company's common shares between June 30, 2025 and December 31, 2025. NioCorp continues as a development stage company and our operating cash outflows for the six-month period totaled $7.6 million. The increase in adjusted net losses for the three- and six-month periods ended December 31, 2025 primarily reflects expenditures associated with the Company's Elk Creek drilling program and its current feasibility study update efforts. NioCorp intends to file its unaudited interim condensed consolidated financial statements for the three- and six-month periods ended December 31, 2025 in its Quarterly Report on Form 10-Q on or before February 16, 2026. 1Non-GAAP Measures The following table presents a reconciliation of the Company's GAAP financial measures to the non-GAAP financial measures referenced above. The Company has included certain non-GAAP financial measures in this press release such as adjusted net loss and adjusted net loss per share. Adjusted net loss for presentation purposes is our net loss plus non-cash items plus (gain)/loss on non-recurring items. These non-GAAP measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP"). Because these non-GAAP performance measures do not have any standardized meaning prescribed by U.S. GAAP, they may not be comparable to similar measures presented by other companies. The Company's management believes that presenting adjusted net loss and adjusted net loss per share provides investors with additional insight into underlying operating performance by excluding the non-cash gains and losses noted above. Our presentation of certain non-GAAP financial measures should not be construed to imply that our future results will be unaffected by the types of items excluded from the calculations of non-GAAP measures. These non-GAAP measures are not presented in accordance with U.S. GAAP and the use of these terms vary from others in our industry. All figures reported above with respect to the three- and six-month periods ended December 31, 2025, are preliminary and are unaudited and subject to change and adjustment as the Company prepares its unaudited interim condensed consolidated financial statements for the three- and six-month periods ended December 31, 2025 and 2024. Accordingly, investors are cautioned not to place undue reliance on the foregoing information. The Company does not intend to provide preliminary results on a regular basis in the future. The preliminary results provided in this news release constitute "forward-looking information" and "forward-looking statements" within the meaning of applicable Canadian and U.S. securities laws, are based on several assumptions and are subject to a number of risks and uncertainties. Actual results may differ materially.

Results Support Ongoing Resource and Reserve Uplift Efforts and Continue to Reinforce the Geological Confidence in the Elk Creek Deposit CENTENNIAL, CO / ACCESS Newswire / January 12, 2026 / NioCorp Developments Ltd. ("NioCorp" or the "Company") (NASDAQ:NB), a leading U.S. critical minerals developer, today announced the final assay results from its completed 2025 drilling campaign at the Elk Creek Critical Minerals Project (the "Elk Creek Project") in southeast Nebraska. The assay results reported are consistent with the Company's expectations and reinforce confidence in the continuity and grade of mineralization within the targeted areas of the Elk Creek deposit. The drilling program focused on areas of the deposit where additional data density was required to support higher confidence classifications under applicable reporting standards. The results are being used to update the Elk Creek Project's Mineral Resource and Mineral Reserve. "These results reflect an excellent job by our colleagues at Dahrouge in targeting the drillholes to intercept the correct geologic units in the ore zone," said Scott Honan, President and Chief Operating Officer of NioCorp. "The highlighted intervals are a further reflection of the robustness and large size of the Elk Creek deposit." "I am very pleased to see the completion of the assay analyses of the more than 7,000 drill core samples that our Department of War-funded infill drilling campaign produced," said NioCorp CEO and Chairman Mark A. Smith. "The results we are seeing are very encouraging. The team is now working diligently to incorporate these results into an updated mineral resource and reserve and mine plan, which is a key component of the updated Feasibility Study that will help the Export-Import Bank of the U.S. complete its diligence of our pending debt financing application." Mr. Smith added: "I am also proud of the fact that NioCorp follows the highest technical standards in conducting this work so that we can meet the compliance requirements of both the Securities and Exchange Commission's SK1300 and Canada's NI 43-101 reporting requirements. Very few critical minerals projects in the U.S. operate with this level of rigor and regulatory compliance, and that fact sets the Elk Creek Project apart from many other projects because it reduces risk and allows investors to have greater confidence in our data and projected financial returns."

CENTENNIAL, CO / ACCESS Newswire / November 5, 2025 / NioCorp Developments Ltd. ("NioCorp" or the "Company") (NASDAQ:NB), a leading U.S. critical minerals developer, is pleased to report assay results from the second diamond drill hole completed as part of the Company's drilling program at its critical minerals project in Southeast Nebraska (the "Elk Creek Project"). The second drill hole was completed to a total depth of 928.42 meters ("m") with a total drill hole length within the carbonatite of 733.42 m and intersected the targeted lithologies over its entire length. Extended intervals of mineralization were observed throughout the entire length of the drill hole, returning several long intervals that are consistent with the existing Mineral Resource model for the Elk Creek deposit. "Results from this second drill hole are consistent with our current geological model and provide additional confirmation of the continuity and grade distribution within the deposit," said Mark A. Smith, NioCorp CEO and Chairman. "Several intervals returned higher-than-expected assay grades. While we do not draw conclusions from individual drill holes, the overall results to date are encouraging. All work is being conducted in accordance with the highest technical standards and in compliance with the Securities and Exchange Commission's S-K 1300 and Canada's NI 43-101 reporting requirements. These results reflect that level of rigor and further support our understanding of the deposit." This drilling program and associated technical work was designed to support the conversion of a portion of the Elk Creek Project's Indicated Mineral Resources into Measured Mineral Resources and the subsequent conversion of a portion of its Probable Mineral Reserves into Proven Mineral Reserves. Assays from the remaining drill holes are being processed by two independent laboratories. Additional results are expected to be released in the next several weeks and final results are anticipated by year-end 2025. Table 1: NEC25-025 - Full DDH Weighted Averages within the Carbonatite The drill hole was designed and oriented parallel to the ore body strike, guided by historical drill hole spacing, to infill geological data within the existing mineral resource.
