Rhea-AI Filing Summary

Rare Element Resources Ltd. reports a Q1 2026 net loss of $2,133, slightly improved from $2,395 a year earlier, as it advances its Bear Lodge rare earth elements project and demonstration-scale processing plant in Wyoming.

Cash and cash equivalents rose to $47,141 and total assets to $52,627, driven mainly by a March 2026 rights offering that raised gross proceeds of $30,968 (net $30,478). The company estimates total demonstration plant costs at about $77,500, with roughly $59,498 spent to date and continued support from a $24,200 U.S. Department of Energy cost-share commitment and a $4,400 Wyoming Energy Authority grant.

Insights

Q1 shows strengthened liquidity but heavy funding needs ahead.

Rare Element Resources reduced its quarterly net loss to $2,133 while significantly bolstering liquidity via a rights offering that generated net proceeds of $30,478. Cash and cash equivalents increased to $47,141, and working capital reached $48,102.

The demonstration-scale rare earth plant remains central. The company now estimates total project costs at about $77,500, with $59,498 already spent. Existing support includes a U.S. DoE cost-share commitment of roughly $24,200 and a $4,400 grant from the Wyoming Energy Authority.

Operations at the Demonstration Plant formally began in March 2026 after design issues and rework in 2025. Management states that current cash, rights-offering proceeds, and remaining DoE and WEA funds should complete the demonstration operations and permitting, but substantial additional capital will be required for a full-scale mine and separation plant.

Demonstration Plant technical
"The Company is currently focused on the advancement of a rare earth processing and separation demonstration-scale plant (the “Demonstration Plant”)."
A demonstration plant is a mid-size, working facility built to prove a new industrial process or technology can operate reliably at near-commercial scale, like a full-size prototype factory. For investors, it matters because successful operation reduces the risk that the technology will fail when scaled up, provides real performance and cost data, and helps attract customers, partners or financing; failures can signal costly setbacks.
Rights Offering financial
"the Company completed a third rights offering in March 2026 for gross proceeds of $30,968 (the “2026 Rights Offering”)."
A rights offering is a way for a company to raise additional money by giving existing shareholders the opportunity to buy more shares at a discounted price before they are offered to the public. It’s similar to a special sale where current owners get the first chance to buy extra items at a lower cost, allowing them to increase their investment if they choose. This process matters to investors because it can affect the value of their holdings and their ability to buy new shares at favorable terms.
Cooperative Agreement regulatory
"The DoE award was finalized through a cooperative agreement, dated October 1, 2021 (the “Cooperative Agreement”), that was awarded by the DoE for the Demonstration Plant."
Cost Share Agreement financial
"the Company and General Atomics entered into a Cost Share Funding Assumption Agreement (the “Cost Share Agreement”)."
WEA Funding Agreement financial
"the Company, and the WEA entered into a Funding Agreement (the “WEA Funding Agreement”) pursuant to which the WEA agreed to fund"
fair value hierarchy financial
"and establishes a fair-value hierarchy that prioritizes the inputs used to measure fair value"

1. NATURE OF OPERATIONS

Rare Element Resources Ltd. (“we,” “us,” “RER” or the “Company”) was incorporated under the laws of the Province of British Columbia, Canada, on June 3, 1999.

The Company holds a 100%  interest in the Bear Lodge rare earth elements project (the “Bear Lodge REE Project”) located near the town of Sundance in northeast Wyoming. The Bear Lodge REE Project consists of several large, disseminated rare earth elements (“REE”) deposits having a favorable distribution of neodymium-praseodymium (NdPr), as well as a number of other critical REEs. Additionally, the Company has developed and enhanced, along with General Atomics and its affiliates, innovative and proprietary REE processing and separation capabilities, currently being tested at the Demonstration Plant (as defined below), for the processing of the Bear Lodge REE Project feed material and possibly feed materials from other sources.

If and when developed, the Bear Lodge REE Project will likely consist of a mine and a separation plant to produce a commercial NdPr product. As market conditions dictate, the Company will decide whether it is prudent to develop and put into production the mine and separation plant independent of each other or whether linking the two production processes into a single project is the more prudent path.

The Company also holds a 100% interest in the Sundance Gold Project that is adjacent to the Bear Lodge REE Project and contains a historical inferred mineral resource primarily composed of three gold targets within the area of the Bear Lodge property (the “Bear Lodge Property”). The Sundance Gold Project has been on hold since 2011 and will likely remain so for the foreseeable future, although with the rise in the price of gold, the Company may explore options to advance or monetize this asset.

The Company is currently focused on the advancement of a rare earth processing and separation demonstration-scale plant (the “Demonstration Plant”). The Demonstration Plant will initially process already stockpiled high-grade sample materials from the Bear Lodge REE Project, and this may be expanded to the processing of feed materials from other sources at some future date. The Company is also focused on advancing the permitting and licensing of the Bear Lodge REE Project, specifically the mine and commercial processing facility.

In January 2021, a consortium of companies, of which the Company is a part, received notice from the Department of Energy (the “DoE”) that the consortium had been selected for negotiation of a potential financial award for the engineering, construction and operation of the Demonstration Plant. The financial award was finalized in October 2021. The Company’s contractual arrangement with General Atomics, an affiliate of Synchron, the Company’s majority shareholder, with respect to the DoE award, was entered into in December 2021. See Note 4 for additional details regarding the consortium arrangement, the Cooperative Agreement, and the Cost Share Agreement with General Atomics.

To address the Company’s funding needs, including the funding required for completion of the Demonstration Plant, the Company completed a third rights offering in March 2026 for gross proceeds of $30,968 (the “2026 Rights Offering”). See Note 7 for additional details regarding the terms of the 2026 Rights Offering and the planned use of proceeds. Previous rights offerings were completed by the Company in December 2021 (the “2021 Rights Offering”) and March 2024 (the “2024 Rights Offering”) for gross proceeds of approximately $25,400 and $35,800, respectively.

Since inception, the General Atomics-led consortium has experienced rising project costs for the Demonstration Plant, including increased final equipment costs, due to inflation, among other factors. The Company currently estimates the total cost of the Demonstration Plant, from inception, to be approximately $77,500, inclusive of projected cost through completion of the Demonstration Plant’s operation phase as discussed below. See Note 4 for additional details regarding the Demonstration Plant budget, DoE funding commitments, and the Cost Share Agreement.

(unaudited)

In December 2022, the Demonstration Plant achieved its final engineering design milestone, marking the DoE’s first go/no-go decision point. A second go/no-go gating milestone was achieved in December 2023 with the issuance by the DoE of a Project Continuation Notice, allowing for the construction of the Demonstration Plant.

In September 2024, the DoE issued its final Project Continuation Notice following its approval of the revised project budget of $53,600 and confirmation of readiness for the operations phase of the Demonstration Plant. This notice, along with the U.S. Nuclear Regulatory Commission’s (the “NRC”) operations approval under its previously issued license (received by the Company in October 2024), allowed for the commencement of Demonstration Plant operations.

Early in 2025, the Company identified several design and equipment issues during the Demonstration Plant’s operational acceptance testing phase, which followed the completion of construction activities. After identifying these issues, the Company assumed full control of the management of the project and initiated a complete design review in April 2025, which identified further operational and safety concerns. The implementation of corrective actions and upgrades commenced immediately thereafter and continued into early 2026. As a result, Demonstration Plant operations did not formally commence until March 2026.

The Company has incurred losses since its inception, and further losses are anticipated in the development of its business. As of March 31, 2026, the Company had cash and cash equivalents of $47,141. During the three months ended March 31, 2026, the Company consumed cash of $2,725 in its operating activities, primarily associated with the Demonstration Plant project activities and for the payment of the Company’s general and administrative expenses and other ongoing costs of sustaining its properties.

The Company currently estimates that with (i) the net proceeds of approximately $30,478 from the 2026 Rights Offering, (ii) the funds on hand prior to the closing of the 2026 Rights Offering, and (iii) the funds it still expects to receive from the DoE and WEA, that it will have sufficient funds to complete the operations stage of the Demonstration Plant, as currently planned, and the licensing and permitting for the Bear Lodge REE Project. Longer-term, in the event the Company cannot secure additional financial resources or complete a strategic transaction, the Company may need to curtail or suspend the development and commercialization of its Bear Lodge REE Project or other initiatives, or potentially liquidate its business interests, and investors may lose all or part of their investment.

2. BASIS OF ACCOUNTING AND PRESENTATION

In accordance with U.S. GAAP for interim financial statements, these unaudited condensed consolidated financial statements do not include certain information and note disclosures that are normally included in annual financial statements prepared in conformity with U.S. GAAP. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of December 31, 2025, which were included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (which are of a normal, recurring nature) necessary to present fairly in all material respects the Company’s financial position as of March 31, 2026, and the results of its operations and cash flows for the three months ended March 31, 2026 and 2025 in conformity with U.S. GAAP on a going concern basis. These interim results of operations for the three months ended March 31, 2026 may not be indicative of the results that will be realized for the full year ending December 31, 2026.

Loss per Share

Loss per share is computed using the weighted average number of shares outstanding during the period. In March 2026, the Company completed the 2026 Rights Offering (see Note 7) whereby the Company offered existing shareholders the right to purchase additional common shares at $0.24 per share (the “Offer Price”).  Because the Offer Price was significantly lower than the market trading price of the common shares at that time, the discounted Offer Price was considered a bonus element, similar to a stock dividend. As a result, the loss per share calculations for the three months ended March 31, 2026 and 2025 have been adjusted retroactively to include the impact of the bonus element.

As of March 31, 2026 and 2025, 820,000 and 1,020,000, respectively, potentially dilutive stock options were considered anti-dilutive and excluded from the Company’s loss per share calculations because the Company was in a net loss position for those periods.

3. FAIR VALUE OF FINANCIAL INSTRUMENTS

U.S. GAAP defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price) and establishes a fair-value hierarchy that prioritizes the inputs used to measure fair value using the following definitions (from highest to lowest priority):

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
Level 2 — Observable inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data by correlation or other means.
Level 3 — Prices or valuation techniques requiring inputs that are both significant to the fair-value measurement and unobservable.

Financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used in such measurements by major security type as of March 31, 2026 and December 31, 2025 are presented in the following table:

4. RELATED PARTY

Cost Share Agreement with General Atomics

In January 2021, a consortium of companies, of which the Company is a part, received notice from the DoE that the consortium had been selected for negotiation of a potential financial award for the engineering, construction, and operation of the Demonstration Plant. This consortium of companies is led by General Atomics, an affiliate of Synchron (the Company’s majority shareholder). A formal proposal was submitted by the consortium in response to a published Funding Opportunity Announcement in mid-2020 for the construction and operation of the Demonstration Plant utilizing proprietary technology to produce commercial-grade products. Under this original proposal, the DoE’s share of the Demonstration Plant project funding was estimated at $21,900 and represented approximately one-half of the total originally estimated costs for the project. The DoE agreement was executed by the DoE’s grants/agreement officer on September 27, 2021, with an effective date of October 1, 2021. The DoE award was finalized through a cooperative agreement, dated October 1, 2021 (the “Cooperative Agreement”), that was awarded by the DoE for the Demonstration

(unaudited)

Plant. The Cooperative Agreement provided that up to approximately $43,800 in allowable costs for the Demonstration Plant were to be funded on a cost-share basis, 50% by the DoE and 50% by a non-federal entity.

On November 30, 2021, the Company and General Atomics entered into a Cost Share Funding Assumption Agreement (the “Cost Share Agreement”) pursuant to which the Company agreed to assume and pay for the 50% of the non-federal funds incurred by, and on behalf of, General Atomics for the design, construction, and operation of the Demonstration Plant under the Cooperative Agreement. The Demonstration Plant will process already stockpiled high-grade sample materials from the Bear Lodge REE Project.

On March 17, 2022, the Company executed a subcontract purchase order in the amount of $5,318 with General Atomics under which the Company agreed to provide certain services and materials to the Demonstration Plant project, including, but not limited to, providing the plant’s sample materials, engaging in site location leases and other logistics, providing operational support, and providing decommissioning, bonding and other Demonstration Plant support activities (the “Subcontract Purchase Order”). In connection with the Subcontract Purchase Order, the Company submitted monthly invoices to General Atomics for the subcontracted services performed, which were reimbursed by General Atomics with one-half of the funds coming from funds advanced by the Company under the Cost Share Agreement and, up to the original Demonstration Plant budget, one-half of the funds from the DoE.

Due to inflationary cost pressures on labor, equipment, and consumables, as well as cost increases associated with certain optimized plant engineering and design parameters, General Atomics, on behalf of the consortium, submitted to the DoE an updated Demonstration Plant project budget of approximately $53,600, which was approximately 22% higher than the original budget of approximately $43,800. In response, the DoE pledged an additional cost-share funding commitment of $2,400 to fund a portion of the budget increase, with the balance coming from the Company, including any amounts in excess of the $53,600 revised budget total. The Company currently estimates the total cost of the Demonstration Plant, from inception, to be approximately $77,500, inclusive of cost estimates through completion of the Demonstration Plant’s operations phase.  

On May 16, 2024, the Company and General Atomics entered into an extension agreement to the Cost Share Agreement (the “Extension Agreement”) under which the Company agreed to make additional cash advances, of up to $2,500, to General Atomics while the parties progressed an amended project funding agreement covering the Company’s share of the additional non-federal project funding needed for the project’s completion. Pursuant to the terms of the Cost Share Agreement and Extension Agreement, the Company had advanced payments to General Atomics, as leader of the consortium, totaling $24,200 through October 31, 2024, the maximum amount of advances authorized under these agreements. In November 2024, General Atomics subsequently returned approximately $3,811 of the amounts previously funded by the Company under the Cost Share Agreement, which were used by the Company, in part, to make payments to certain other contractors for work under the Cost Share Agreement. The payments to these other contractors, all made in November 2024 and on General Atomics’ behalf, totaled to $4,746.

In September 2025, at the Company’s request, General Atomics and the Company formally requested a novation of the financial assistance agreement between General Atomics and the DoE, under which General Atomics’ interests under the agreement would be transferred to the Company. The novation process, which is underway and is expected to be completed during 2026, will not change the intellectual property rights held by Synchron and its affiliates in the Company’s intellectual property. Once the novation process is complete, the Company will be named the recipient of the award under the agreement and certain conditions are expected to be confirmed, including the potential for additional DoE funding for further advancements of the Demonstration Plant under an amended or separate financial assistance agreement.  

The DoE has allowed the novation process to progress even though the financial assistance agreement’s term expired on September 30, 2025. If a novation is not completed, the DoE award to General Atomics could be terminated, and final disposition of the assets and decommissioning activities would be negotiated with the DoE. Although the Company expects the novation process to be completed in 2026, there is no assurance of the process progressing in a timely manner or being completed at all.

Since inception, the Company has (i) advanced $20,389 in funds to General Atomics under the Cost Share Agreement, (ii) paid an additional $4,746 on General Atomics’ behalf to certain contractors for work performed under the Cost Share Agreement and (iii) paid

5. WYOMING ENERGY AUTHORITY GRANT

In June 2023, the Company, and the WEA entered into a Funding Agreement (the “WEA Funding Agreement”) pursuant to which the WEA agreed to fund, subject to certain conditions, a $4,400 grant to the Company, the proceeds of which are to be used for the Demonstration Plant. Pursuant to the WEA Funding Agreement, the grant is to be paid upon the WEA’s receipt of invoices from the Company detailing its actual expenses relating to the Demonstration Plant (half of which funds will be allocated to two milestone periods during the development process), less a 10% retainer, the payment of which is conditioned upon the WEA’s receipt, following the commencement of the Demonstration Plant’s operations, of an invoice and the Company’s final executive summary report in a form to be approved by the WEA. Pursuant to the WEA Funding Agreement, the funding for the Demonstration Plant will be provided to the WEA from the Energy Resources Council (the “ERC”) and is further conditioned upon the availability of government funds that are appropriated or allocated for the payment of the grant and which may be limited for any reason, including congressional, legislative, gubernatorial, or administration action.

The WEA Funding Agreement will terminate when the funding has been fully disbursed, but no later than June 30, 2026, unless terminated sooner by either party in accordance with the terms of the WEA Funding Agreement. The WEA Funding Agreement may be terminated (i) by either party if the WEA does not receive the requested funding from the ERC or if the grant funds are not allocated or available for the continued performance of the WEA Funding Agreement, or (ii) by the WEA immediately for cause if the Company fails to perform in accordance with the terms of the WEA Funding Agreement.

As of December 31, 2023, the Company had met the conditions allowing for the invoicing of $2,000 of the $4,400 WEA grant total. This $2,000 was subsequently received on January 31, 2024. By September 30, 2024, the Company had met the conditions allowing for the invoicing of an additional $2,000, which was subsequently received in November 2024. The remaining $400 of the $4,400 grant total, which is conditioned on the achievement of other, future milestones, will be invoiced to the WEA once those final milestones have been achieved, which are currently expected to occur in mid-2026.

6. LEASES

Effective September 21, 2021, the Company entered into a lease agreement (the “Property Lease”) for real property, including land and buildings in Upton, Wyoming for the Demonstration Plant. The Property Lease, which had an initial 12-month term, allows for annual renewals, which at the Company’s option can be renewed for as long as the facility is needed. In June 2025, the Property Lease was renewed, extending the termination date to September 30, 2026 and another 12-month extension is expected in June 2026 extending the lease through September 30, 2027.

The Property Lease, which is classified as an operating lease, generally provides for base rent, and requires the Company to pay all insurance, personal property taxes on any structure or improvements made by the Company and other maintenance costs. The Property Lease provides for an annual cost of living adjustment but contains no residual value guarantees or restrictive covenants. Pursuant to the Property Lease, the Company is obligated to remove certain Company completed property improvements, though those items requiring removal, if any, will be confirmed with the lessor prior to the termination of the Property Lease.

2026 Rights Offering

On March 4, 2026, the Company completed the 2026 Rights Offering for gross proceeds of $30,968 in which each holder of the Company’s common shares as of the record date of January 30, 2026, was eligible to participate. Terms of the 2026 Rights Offering included the issuance of twenty-five hundredths (or 0.25) of a subscription right for each common share owned by each holder on the record date, with each subscription right entitling the holder to purchase one common share of the Company at a subscription price of $0.24 per share (the “Basic Subscription Privilege”). For any holder exercising its Basic Subscription Privilege in full, the holder could also exercise an oversubscription privilege to purchase additional common shares that were unsubscribed for at the expiration of the 2026 Rights Offering, subject to availability and pro rata allocation of shares among persons exercising the oversubscription privilege. The 2026 Rights Offering, which generated $30,478 in net proceeds after deducting $490 in transactions costs, resulted in the issuance of 129,033,678 common shares of the Company.

After adjustment for the bonus element included in the 2026 Rights Offering (see Note 2), the weighted average number of shares outstanding used in the Company’s loss per share calculations for the three months ended March 31, 2026 increased from 553,548,886 shares to 623,924,888 shares and for the three months ended March 31, 2025 from 516,114,475 shares to 586,505,290 shares.

8. COMMITMENTS AND CONTINGENCIES

Potential environmental contingency

The Company’s exploration and development activities are subject to various federal and state laws and regulations governing the protection of the environment. These laws and regulations are continually changing and generally have become more restrictive. The Company conducts its operations to protect public health and the environment and believes that its operations are materially in compliance with all applicable laws and regulations. The Company has made, and expects to make in the future, expenditures to comply with such laws and regulations. The ultimate amount of reclamation and other future site restoration costs associated with the Company’s existing mining interests is uncertain and may exceed current estimates. As of March 31, 2026 and December 31, 2025, these costs were estimated at $185 for each respective period.

Contract commitment – related party

Pursuant to the Cost Share Agreement between the Company and General Atomics, as extended and as expected to be amended in 2026, if required (see Note 4), the Company has agreed to assume and pay for certain allowable costs under the DoE-approved Demonstration Plant budget incurred by General Atomics and the other consortium members for the design, construction, operation, and decommissioning of the Demonstration Plant.

9. GEOGRAPHIC AND SEGMENT INFORMATION

The Company operates in a single reportable operating segment: that segment being minerals exploration and development. The Company’s sole minerals exploration property is its Bear Lodge Property, located near the town of Sundance in the state of Wyoming. The segment, which includes the Demonstration Plant project, does not presently generate any revenues and is not in commercial operation. The Company’s chief executive officer, who is the chief operating decision maker, reviews financial information on an aggregate basis for evaluating financial performance.  All of the Company’s long-lived assets are associated with its Bear Lodge Property and are located in the United States.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following management’s discussion and analysis of the consolidated financial results and condition of Rare Element Resources Ltd. (collectively, “we,” “us,” “our,” “RER” or the “Company”) for the three months ended March 31, 2026, has been prepared based on information available to us as of May 13, 2026. This discussion should be read in conjunction with the unaudited Condensed Consolidated Financial Statements and notes thereto included herewith and the audited Consolidated Financial Statements of RER for the year ended December 31, 2025, and the related notes thereto filed with our Annual Report on Form 10-K for the year ended December 31, 2025, which have been prepared in accordance with U.S. GAAP. This discussion and analysis contains forward-looking statements that involve risks, uncertainties, and assumptions. Our actual results, performance, or achievements may differ materially from those anticipated in these forward-looking statements as a result of many factors, including, but not limited to, those set forth elsewhere in this Quarterly Report. See “Cautionary Note Regarding Forward-Looking Statements.”

All currency amounts are expressed in thousands of U.S. dollars, unless otherwise noted.

Overview and Outlook

Our primary focus is on the operation of the Demonstration Plant, and as of late 2025, the resumption of licensing and permitting activities for our Bear Lodge REE Project. The licensing and permitting efforts are expected to continue into early 2028.

If successful, the Demonstration Plant will show that our proprietary extraction technology is able to process and separate certain REEs from high grade sample materials extracted from our Bear Lodge REE Project in a more efficient and economical manner than traditional REE processing methods and will serve as a precursor to inform the design and estimated cost for a full-scale production facility.

In September 2024, the DoE issued its final Project Continuation Notice, confirming the Demonstration Plant’s readiness for operations. This notice, along with the NRC’s approval of operations received in October 2024, cleared the path for operations of the Demonstration Plant to formally commence, with operations to process and separate REEs from the previously stockpiled high-grade sample materials from the Bear Lodge REE Project. During the three months ended March 31, 2026, the Company continued work on the Demonstration Plant project as described below, and this work is expected to continue until the completion of the Demonstration Plant’s operations.

In early 2025, several design and equipment issues were identified during the Demonstration Plant’s equipment testing phase. As a result of these issues, we initiated an as-built design review in April 2025. Following the review and related project rework, Demonstration Plant operations formally commenced in March 2026 and are expected to continue for up to 12 months. During the operations phase, the Demonstration Plant is expected to produce up to 10 tons of NdPr oxide.

In June 2023, the Company entered into the WEA Funding Agreement for a $4,400 grant from the WEA to be used toward the advancement of the Demonstration Plant. As of March 31, 2026, the Company had received $4,000 of the $4,400 WEA grant total. The remaining $400 of the $4,400 grant total, which is conditioned on Demonstration Plant operations and a report to the WEA, is currently expected to be invoiced in mid-2026. See Note 5 to the Condensed Consolidated Financial Statements for additional details regarding the WEA Funding Agreement.

As discussed in Note 4 to the Condensed Consolidated Financial Statements, the Demonstration Plant’s project costs, have increased since inception, due to inflation and other factors. The Company currently estimates the total cost of the Demonstration Plant from inception, inclusive of operating cost estimates through completion of the Demonstration Plant’s operations phase, to be approximately $77,500. 

Through March 31, 2026, the DoE had made payments totaling approximately $20,500 towards its commitment of approximately $24,200, leaving a balance of approximately $3,700 to be collected from the DoE under the current cost share award.

To fund the Company’s share of these cost increases, in March 2026, the Company completed the 2026 Rights Offering for gross proceeds of $30,968. See Note 7 to the Condensed Consolidated Financial Statements for additional details regarding the terms of the 2026 Rights Offering. The 2026 Rights Offering closed on March 4, 2026, generating net proceeds of $30,478. These funds, in conjunction with the funds already on hand and those funds still expected to be received from the DoE and WEA, will be used to progress the Company’s business strategy, which includes (i) the continued operation of the Demonstration Plant for a sufficient time to provide

15

Table of Contents

the information to support a commercialization decision, (ii) the advancement of projects for the as-constructed Demonstration Plant beyond the current NdPr separation objectives, including applying the technology to the separation of HREEs and possibly to third party feed sources, (iii) the completion of federal and state permitting and licensing for the Bear Lodge REE Project, and (iv) other general corporate purposes.

Even with the funds already on hand, the funds raised in the 2026 Rights Offering, and the expected receipt of the remaining WEA grant monies and DoE funds, the Company will still require additional funding to design, construct, and operate the Bear Lodge REE Project.

Ultimately, in the event the Company cannot secure additional financial resources or complete a strategic transaction, the Company may need to curtail its plans for the Demonstration Plant, suspend permitting and development of the Bear Lodge REE Project or other initiatives, or potentially liquidate its business interests, and investors may lose all or part of their investment.

Current External Factors Impacting our Business

During the first three months of 2026, we continued to monitor the U.S. political climate and federal actions aimed at securing a domestic REE supply chain. The Trump Administration has sustained and expanded initiatives from prior years to reduce reliance on China-dominated REE supply chains and strengthen the U.S. defense industrial base.

Key developments in 2025 and early 2026 include:

Multiple Executive Orders directing federal agencies to fast-track permitting, funding, and offtake agreements for domestic critical mineral projects, with specific emphasis on REE processing and national defense stockpiles.
The April 2025 Section 232 investigation into imports of processed critical minerals (focused on REEs), which culminated in a January 2026 Presidential Proclamation declaring current import levels a national security threat and directing negotiations for “Critical Mineral Trade Agreements” with allies.
The DoE’s December 2025 announcement of $134,000 in targeted funding for REE separation, refining (particularly HREEs), and permanent magnet production.
In January 2026, the Administration’s proposed G7-level price floor mechanism for neodymium-praseodymium (NdPr) and other magnet-related rare earths designed to protect domestic producers from price volatility.
In February 2026, President Trump’s “Project Vault,” a $12,000,000 U.S. Strategic Critical Minerals Reserve structured as a public-private partnership with $10,000,000 in EXIM Bank backing was announced. The program is designed to serve as a “buyer of last resort” for U.S.-processed REEs, providing guaranteed offtake and shielding domestic producers from foreign export restrictions and predatory pricing.

In October 2025, China announced enhanced export controls covering 12 of 17 REEs, including extraterritorial requirements for foreign-produced items containing even 0.1% Chinese-origin REEs or manufactured using Chinese refining equipment, as well as a prohibition on REE exports for military applications. Following a meeting between President Trump and Chinese President Xi Jinping on October 30, 2025, China agreed to suspend these enhanced controls, along with certain other related curtailments, for one year as part of a broader trade truce. As of March 2026, no new Chinese restrictions have been announced, and REE export volumes from China have increased following streamlined licensing. The Company continues to monitor these developments, as ongoing geopolitical tensions and U.S. tariffs/trade measures could affect REE supply chains and our project economics.

The U.S. government has also accelerated direct financial support for domestic REE and critical minerals projects throughout 2025 and early 2026, including equity or warrant participation and infrastructure funding. The Company continues to evaluate opportunities to participate in these programs.

Other external factors, including the lingering effects of the COVID-19 pandemic, the Russia/Ukraine conflict, and Middle East conflict, including the Iran War, have reinforced the U.S. focus on secure domestic supply chains for REEs and critical minerals.  The ultimate impact of these evolving U.S. and Chinese government actions on the REE supply chain and our business operations remains uncertain.

Results of Operations

Summary

Our consolidated net loss for the three months ended March 31, 2026 was $2,133, or $0.00 per share, compared with our consolidated net loss of $2,395, or $0.00 per share, for the three months ended March 31, 2025. See our discussion below for the primary drivers of this change. As an exploration stage company, we had no properties in production and generated no revenues during either period.

Exploration and Evaluation

Our exploration and evaluation costs totaled $1,719 for the three months ended March 31, 2026, compared with $1,877 for the three months ended March 31, 2025. This decrease of $158 was largely attributable to the activities associated with our Demonstration Plant as we shifted from final construction and testing activities during the quarter ended March 31, 2025, to plant rework and operations start-up activities during the quarter ended March 31, 2026.

Corporate Administration

Our corporate administration costs decreased by $170 on a comparative year-over-years basis, decreasing from $750 for the three months ended March 31, 2025 to $580 for the three months ended March 31, 2026. This decrease was largely attributable to the additional costs incurred in the filing of our Form S-3 registration statement during the three months ended March 31, 2025.

Interest Income

For the three months ended March 31, 2026 and 2025, the Company generated interest income of $213 and $284, respectively, on investments of its cash holdings. This decrease of $71 was primarily due to the lower rates of interest earned on our invested cash balances during the quarter ended March 31, 2026.

Financial Position, Liquidity and Capital Resources

Operating Activities

Net cash used in operating activities was $2,725 for the three months ended March 31, 2026, compared with $2,269 for the same period in 2025. This increase of $456 was largely attributable to changes in our working capital that consumed $646 of cash during the three months ended March 31, 2026, while generating cash of $77 during the three months ended March 31, 2025.

Investing Activities

Net cash used in investing activities of $59 for the three months ended March 31, 2025 was for the purchase of equipment.  There were no similar transactions during the comparative 2026 period.

Financing Activities

Net cash provided by financing activities of $30,553 for the three months ended March 31, 2026 stemmed from the receipt of $30,478 in net proceeds from the 2026 Rights Offering and $75 from the exercise of stock options.  There were no similar transactions during the three months ended March 31, 2025.

Financial Position, Liquidity and Capital Resources

At March 31, 2026, we had a working capital balance of $48,102, which was an increase of $28,436 from our December 31, 2025 working capital balance of $19,666. This increase was largely the result of the net proceeds received from the 2026 Rights Offering, partially offset by operating cash flows.

Table of Contents

As discussed in Note 5 to the Condensed Consolidated Financial Statements, the Company entered into the WEA Funding Agreement in June 2023 for a $4,400 grant. As of March 31, 2026, the Company had received $4,000 of the $4,400 grant total, with the remaining $400 forecasted for collection in mid-2026.

As discussed in Note 4 to the Condensed Consolidated Financial Statements and in “Overview and Outlook” above, the Demonstration Plant’s project costs have increased since inception. The DoE pledged an additional commitment of $2,400 (increasing its total commitment to approximately $24,200) in September 2024 to help fund a portion of this budget increase, with the balance to be funded by the Company, including any amounts in excess of the $53,600 revised budget total. The Company currently estimates the total Demonstration Plan project cost to be approximately $77,500, inclusive of cost estimates through the Demonstrations Plant’s operations phase.

Through March 31, 2026, the DoE has paid a total of approximately $20,500 towards its commitment of approximately $24,200, leaving a balance of approximately $3,700 to be invoiced and collected from the DoE under the current cost share award.

As discussed in Note 1 to the Condensed Consolidated Financial Statements and in “Overview and Outlook” above, design and equipment issues identified in early 2025 led to a complete design review and the implementation of corrective actions and upgrades that continued into 2026, with Demonstration Plant operations formally commencing in March 2026.

The funds raised by the Company in the 2026 Rights Offering (see Note 7 to the Condensed Consolidated Financial Statements), in conjunction with the funds already on hand and those funds expected to be received from the DoE and WEA, will be used to progress the Company’s business strategy as described in “Overview and Outlook” above. However, even with these funds, the Company will still require substantial additional funds to complete the design, construction, and operation of a commercial mine and plant for the Bear Lodge REE Project.

Ultimately, in the event the Company cannot secure additional financial resources or complete a strategic transaction, the Company may need to curtail its plans for the Demonstration Plant, suspend permitting and/or development of the Bear Lodge REE Project or other initiatives, or potentially liquidate its business interests, and investors may lose all or part of their investment.

Contractual Obligations

Financial Assistance Agreement

As discussed in Note 4 to the Condensed Consolidated Financial Statements, in September 2025, at the Company’s request, General Atomics and the Company formally requested a novation of the financial assistance agreement between General Atomics and the DoE. If completed, the Company would be named the recipient of the award under the novated agreement and certain conditions are expected to be confirmed, including the potential for additional DoE funding support for further advancements of the Demonstration Plant.
