**CAUTIONARY NOTE REGARDING RESERVES** 

Unless otherwise indicated, all mineral resource and reserve estimates included in this report have been prepared in accordance with, and are based on the relevant definitions set forth in, the SEC's Mining Disclosure Rules and Regulation S-K 1300 (each as defined below). Mining disclosure in the United States was previously required to comply with SEC Industry Guide 7 (the "SEC Industry Guide 7") under the Exchange Act. In accordance with the SEC's Final Rule 13-10570, Modernization of Property Disclosure for Mining Registrant, the SEC has adopted final rules, effective February 25, 2019, to replace SEC Industry Guide 7 with new mining disclosure rules (the "Mining Disclosure Rules") under sub-part 1300 (Title 17, Part 229, Items 601 and 1300 until 1305) of Regulation S-K ("Regulation S-K 1300") of the Securities Act. Regulation S-K 1300 replaces the historical property disclosure requirements included in SEC Industry Guide 7. Regulation S-K 1300 uses the Committee for Mineral Reserves International Reporting Standards ("CRIRSCO")-based classification system for mineral resources and mineral reserves and accordingly, under Regulation S-K 1300, the SEC now recognizes estimates of "Measured Mineral Resources," "Indicated Mineral Resources" and "Inferred Mineral Resources," and require SEC-registered mining companies to disclose in their SEC filings specified information concerning their mineral resources, in addition to mineral reserves. In addition, the SEC has amended its definitions of "Proven Mineral Reserves" and "Probable Mineral Reserves" to be substantially similar to international standards. The SEC Mining Disclosure Rules more closely align SEC disclosure requirements and policies for mining properties with current industry and global regulatory practices and standards, including the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, referred to as the "JORC Code." While the SEC now recognizes "Measured Mineral Resources," "Indicated Mineral Resources" and "Inferred Mineral Resources" under the SEC Mining Disclosure Rules, investors should not assume that any part or all of the mineral deposits in these categories will be converted into a higher category of mineral resources or into mineral reserves. Investors are also cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources are guarantees of actual resource amounts or that such amounts will be economically or legally mineable.

The following terms, as defined in Regulation S-K 1300, apply within this report:

---

| | |
|:---|:---|
| *Measured Mineral Resource*<br>("Measured" or "Measured Mineral Resource") | &nbsp;&nbsp;is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve. |
| *Indicated Mineral Resource*<br>("Indicated" or "Indicated Mineral Resource") | &nbsp;&nbsp;is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve. |
| *Inferred Mineral Resource*<br>("Inferred" or "Inferred Mineral Resource") | &nbsp;&nbsp;is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a mineral reserve. |
| *Probable Mineral Reserve*<br>("Probable" or "Probable Mineral Reserve") | &nbsp;&nbsp;is the economically mineable part of an indicated and, in some cases, a measured mineral resource. |
| *Proven Mineral Reserve*<br>("Proven" or "Proven Mineral Reserve") | &nbsp;&nbsp;is the economically mineable part of a measured mineral resource and can only result from conversion of a measured mineral resource. |

**PART I**

## Items 1 and 2. Business and Properties

## Overview
We are a development stage company focused on becoming a vertically integrated global leader and supplier of refined borates and advanced boron derivative materials whose mission is to enable decarbonization, increase food security, and ensure domestic supply of critical materials. Our business strategy and objectives are to develop capabilities ranging from upstream extraction and product sales of borates, calcium-based co-products, and potentially other byproducts such as lithium carbonate, to downstream advanced boron material processing and development. Our vision is to safely process borates and other industrial materials through sustainable best practices and a continuous improvement mindset. We hold 100% of the rights through ownership and lode claims filed with the United States Bureau of Land Management in the 5E Boron Americas (Fort Cady) Complex located in southern California (the "Project"), through our wholly owned subsidiary 5E Boron Americas (formerly Fort Cady (California) Corporation ("5EBA")). Our Project is underpinned by a mineral resource that includes boron and lithium, with the boron being contained in a conventional boron mineral known as colemanite. In 2022, our facility was designated as Critical Infrastructure by the Department of Homeland Security's Cybersecurity and Infrastructure Security Agency. We currently operate our small-scale facility (the "SSF") at the Project, which provides data and information necessary for us to ultimately establish a commercial-scale facility at the Project.

Through a multi-phased approach, we plan to develop the Project into a large-scale boron and lithium complex. The Project is based on a conventional colemanite deposit, which is a hydrated calcium borate mineral found in evaporite deposits, and we believe it is one of the largest known new conventional boron deposits globally. The deposit hosts a mineral resource and reserve from which we intend to extract and process into borates, advanced boron materials, calcium-based co-products, and potentially other byproducts such as lithium carbonate on a commercial scale. These materials are scarce in resource, currently subject to supply risk as a large portion of their consumption in the United States is sourced from foreign producers and are essential for supporting critical industries. When the Project is successfully developed, we believe that we can become an important supplier helping to provide supply security for these materials in the United States. The importance of the Project and its mineral resources and reserves have been recognized by it being designated as Critical Infrastructure by the Department of Homeland Security's Cybersecurity and Infrastructure Security Agency. The Project is also expected to serve as an important supply source of borates that we intend to process and develop into refined borates and advanced boron materials over time.

## Our Strengths
We believe the following key strengths will help us toward our goal of becoming an important supplier of refined borates and advanced boron materials, complemented by calcium-based co-products and potentially other byproducts such as lithium carbonate:

***Strategically Positioned to Benefit from Expected Substantial Demand Growth as Boric Acid Demand Out Paces Supply, Fueled by Intensified Decarbonization Efforts and Future Facing Market Developments.*** We are a development-stage company aiming to develop a materials reserve of high-quality borates and other key industrial materials, currently positioned as inputs into key technologies and industries that address climate change, support decarbonization, energy independence, and support food, national security and defense sectors. We believe factors such as government regulation and incentives focused on domestic manufacturing and supply chains and capital investments across industries will drive demand for end-use applications like solar and wind energy infrastructure, neodymium-ferro-boron magnets, defense applications, lithium-ion batteries, and other critical material applications. We expect any such growth in demand to increase the need for borates and other advanced boron materials that we seek to produce. In addition, products with future facing applications, including in the semi-conductor, life sciences, aerospace, military and automotive markets, are also expected to drive demand growth. As a result of our broader focus on the refined borates and advanced boron materials rather than specific end use applications, we believe we can be well-positioned to be an important domestic supplier to a number of different sectors benefiting from their expected growth.

***Attractive Geographic Location with a Potential to Address Global Supply Challenges and National Security Concerns.*** Over the past several years, the United States has taken action to reinforce existing supply chains and access to critical materials, while working to secure the domestic supply. In February 2022, the Project was designated as Critical Infrastructure by the Department of Homeland Security's Cybersecurity and Infrastructure Security Agency, which we believe is a testament to its potential importance as a U.S.-based source of boron, lithium and other materials. This designation supports our goal of playing an important role in providing critical materials domestically, while simultaneously addressing the currently challenged global supply chain. The global boron market is exposed to potential supply risks. There are currently only two major global suppliers (Eti Maden and Rio Tinto Borax) who together represent approximately 80-85% of total supply, with Eti Maden representing approximately 60% of global supply. Similarly, there are only a small number of domestic lithium carbonate suppliers today in the United States. The Project is located in Southern

------

California and, if successfully commercialized, we expect it will have the ability to supply U.S. markets and industries with these two key materials, become a driver of exported goods, and thereby help reduce reliance on foreign sources and potentially bolster the United States economic growth. Our plans to develop U.S.-based downstream capabilities are similarly expected to allow us to onshore additional components of the overall boron supply chain that have historically been concentrated in Asia and other foreign regions.

***Our Project is Based on one of the Largest Known New Conventional Boron Deposits in the World and Includes a Complementary Lithium Resource that has the Potential to Enable Us to Become an Important Participant in the U.S. Lithium Market.*** The Project deposit is a rare colemanite borate deposit, and we believe it is one of the largest known new deposits of colemanite globally. The Preliminary Feasibility Study estimates a combined 5.3 million short tons ("MST") of boric acid (H3BO3) proven and probable reserves for Phase 1 of the Project, and 169 thousand short tons of measured plus indicated mineral resource of lithium carbonate equivalent. The mineral resource estimate also identified 0.5 million short tons of inferred mineral resource of boric acid (H3BO3) and 5 thousand short tons of lithium carbonate equivalent. All reserve and mineral resource estimates were prepared using a 2.0% cut-off grade. We believe that the complementary lithium resource at the Project, if successfully developed, has the potential to enable us to become an important participant in the U.S. lithium market. We believe the size and quality of our Project's boron reserves and lithium resource also positions us to become a long-term supplier, if and when the site becomes operational.

***We Believe Our Approach for Developing and Commercializing the Project, along with our Orientation towards Decarbonization-Enabling Materials and Industries can Position us Well to Focus On Sustainability Initiatives.*** We believe that the boron and lithium materials we plan on producing will support industries and applications that enable decarbonization and emission reduction, such as electric vehicles and green energy. These industries are important contributors to and supporters of the United Nations Sustainability Development Goals ("SDG's"), which include accelerating a net-zero future, promoting sustainable infrastructure, improving global nutrition and health as well as promoting innovation. Further, we believe that our extraction techniques will help us create a set of infrastructure that is aligned with the industries we plan on supporting. Our method of in-situ extraction is expected to source water from our hydrology wells while providing for closed loop water recycling which we expect will help reduce overall water consumption and provide for efficient energy management. In-situ extraction is also traditionally associated with less above ground land disturbance than traditional resource extraction methods, while using fewer fossil fuels. Given our early stage of development, we believe we have a unique opportunity to develop and grow our business and a potential sustainability advantage, including building a Board and leadership team as well as creating strong corporate governance policies, in each case focused on sustainability matters. Our focus will be to have a positive impact on the prosperity of local communities by supporting job creation, providing specialized training, targeting local procurement and investment, all of which are important given the local community near the Project is designated an economic development zone by the State of California.

## Our Strategy
Our strategy is founded on leveraging our large mineral resources and reserves, related proposed infrastructure project, project development and advanced materials expertise to develop a vertically integrated business focused on refined borates and advanced boron materials, complemented by calcium-based co-products of calcium chloride and gypsum, and strategically extract and process economically accretive byproducts such as lithium carbonate. We intend to continue to thoughtfully develop our business over time in a systematic manner.

In November 2023, the U.S. Environmental Protection Agency ("EPA") provided authorization to begin in-situ mining operations pursuant to an Underground Injection Control permit and in January 2024, we began well-field injection with acid and began extracting valuable minerals from the Project in the form of a Pregnant Leach Solution ("PLS"). The initial high-quality run-of-mine head grade of boric acid provided validation of our initial operational assumptions.

In April 2024, we commenced operation of the SSF, an above ground chemical plant designed to refine borates, which has served as a foundation for the design, engineering, and cost optimization for our proposed commercial-scale facility, as well as serving as the source of product for our customer qualification and offtake agreement efforts. The SSF is an essential step in the overall Project development plan and serves as our current extraction and processing facility to demonstrate product development and design. Shortly after we began to process the PLS at the SSF we produced our first batch of boric acid. During July 2024, we sent out our first samples of boric acid produced at the SSF to potential customers, and during April 2025, we were notified by a leading global specialty glass manufacturer that they had successfully produced specialty glass utilizing our boric acid. As of September 2025, we were aware of approximately 14 customers in 8 diverse market segments who had successfully qualified our boric acid through a combination of laboratory evaluation, field trials and truckload-scale shipments. We believe that the progress observed in our customer qualification efforts will facilitate discussions with stakeholders about funding options for Phase 1 of the commercial facility and securing commercial contracts for our future products.

------

Concurrently with the commissioning of wellfield and start-up of the SSF, during January 2024 we selected Fluor Enterprises, Inc. ("Fluor") as our Engineering, Procurement and Construction Management Firm ("EPC") service provider to lead our FEL-2 engineering program. During August 2025, Fluor completed the FEL-2 engineering for our proposed commercial-scale facility, which culminated in the issuance of a S-K 1300 compliant Preliminary Feasibility Study (the "PFS"). The PFS included a capital estimate of approximately $435 million to construct the proposed commercial-scale facility, inclusive of $55 million for contingency and approximately $13 million of owner's costs, and resulted in approximately 41% of the Project's total resource being converted into approximately 5.3 million short tons of boric acid reserves, and a resultant 39.5 year life of mine.

We plan to continue to operate the SSF to produce additional boric acid for potential customers, advance the design of our commercial-scale wellfield design and operating methods, and refine the production process for our two proposed byproducts; calcium chloride and gypsum. Our expectation is that the SSF will cease operation and be decommissioned once we advance to the commercial construction stage for our proposed commercial-scale facility.

While our immediate focus is on our efforts to establish the proposed commercial-scale facility and our ability to commercially produce salable products, including boric acid, calcium chloride and gypsum, we remain dedicated to opportunistically developing downstream advanced boron materials processing capabilities and economically accretive byproducts such as lithium carbonate to extract greater value out of the Project.

***Key elements of our strategy include:***

***Develop and Commercialize the Project to Produce an Economical and Secure Supply of Boron and Focusing on a more Environmentally Friendly In-Situ Extraction Process as Compared to Traditional Mining.*** Our initial objective is to develop our Project's boron resource and achieve a commercial extraction volume of borates and other byproducts safely and profitably with an aim to rely on a more environmentally friendly in-situ extraction process as compared to traditional mining. The SSF, which commenced operations in April 2024, has proven the technical merits of our planned in-situ mining techniques, and has served as the foundation for our future design, engineering, and cost optimization of our planned commercial-scale complex while simultaneously providing product samples for customer qualification and offtake agreement efforts. If and when the commercial-scale complex is fully operational, we believe that we will have an opportunity to be a long-term supplier of borates, calcium chloride and gypsum, and the Project can serve as an important internal supply source for our development of downstream specialty and advanced materials.

***Establish Competitive Market Positions in High Value, High Margin Markets for Refined Borates and Advanced Boron Materials that Address Decarbonization, Food Security, National Security and Defense, and Production of Domestic Supply***. We are seeking to establish competitive market positions in high value in use, high margin, and high technology refined borates and advanced boron materials markets. We believe that as a result of efforts by several countries and businesses to address climate change and achieve decarbonization, as well as increasing challenges related to food security and geopolitical instability, key sectors such as electric vehicle manufacturing, clean energy infrastructure, food and fertilizers, and domestic security, will experience significant growth in the future. As a result, these sectors are expected to require secure and substantial new supplies of key inputs such as boron to support their growth. Assuming the successful commercial completion of our proposed commercial-scale facility and complex, we believe we will have the opportunity to become one of the largest suppliers of borates in the domestic U.S. and international markets. Over time, we plan on developing downstream advanced boron materials capabilities to convert borates into advanced boron materials. These advanced boron materials may support higher technology applications across the fields of semi-conductors, life sciences, aerospace, military, energy and automotive markets and would allow us to extract greater value from our processes and supply chain. Downstream advanced boron materials capabilities may be developed over time through a combination of internal research and development, commercial partnerships or joint ventures with other organizations or research institutions, or via the acquisition of intellectual property related to processing and manufacturing.

***Sign Offtake Agreements and Develop Commercial Partnerships to Expand High-Performance Boron Capabilities and Embed Ourselves in Customer Supply Chains.*** As part of the commercialization plans for the Project, we plan on dedicating resources for marketing efforts to establish commercial offtake agreements for the sale of borates, calcium chloride and gypsum. We believe sales of these materials will support our strategy of achieving a durable revenue base, which can be used to fund subsequent incremental capacity plans and generate cash necessary for investments in downstream advanced boron materials capabilities and economically accretive byproducts such as lithium carbonate. As we develop our downstream materials business, we plan to collaborate with customers and partners to support their development of high-performance applications in the areas of clean energy infrastructure, electric transportation, and high-grade fertilizers among other end uses. These commercial partnerships are expected to be an important element of embedding us within global supply chains and positioning us as an essential supplier of borates and advanced boron materials. We intend to invest in research and development initiatives with an aim to support our customers' product development and create intellectual property for us.

## Corporate History and Reorganization
American Pacific Borates Limited, our former parent company, was incorporated in October 2016 under the laws of Western Australia for the purpose of acquiring the rights in the Project from Atlas Precious Metals, Inc. The acquisition of Fort Cady (California) Corporation was completed in May 2017 and ABR's ordinary shares were subsequently admitted for official quotation on the Australian Stock Exchange ("ASX") in July 2017.

We were incorporated in the State of Delaware on September 23, 2021, as a wholly owned subsidiary of ABR for the purposes of effecting a corporate reorganization.

We received all the issued and outstanding shares of ABR pursuant to a statutory Scheme of Arrangement under Part 5.1 of the Australian Corporations Act ("Scheme"). The Scheme was approved by ABR's shareholders at a general meeting of shareholders held on December 2, 2021. Following shareholder approval, the Scheme was approved by the Federal Court of Australia on February 24, 2022.

After completion of the Scheme, we listed our Common Stock on Nasdaq under the symbol "FEAM" on March 15, 2022 and de-listed ABR from the ASX on March 8, 2022.

Pursuant to the corporate reorganization, we issued to the shareholders of ABR either one share of our Common Stock for every ten ordinary shares of ABR or one CDI for every one ordinary share of ABR, in each case, as held on the Scheme record date. Eligible shareholders of ABR (those whose residence at the record date of the Scheme is in Australia, New Zealand, Canada, Hong Kong, Ireland, Papua New Guinea, Singapore, Malaysia, Thailand, or the United States) received CDIs by default. In order to receive Common Stock, eligible shareholders were required to complete and submit an election form to ABR's registry no later than 5:00 p.m. (AEDT) on March 2, 2022. Ineligible shareholders did not receive CDIs or shares of Common Stock but instead received the proceeds from the sale of the CDIs to which they would otherwise have been entitled by a broker appointed by ABR. The appointed broker sold the CDIs in accordance with the terms of a sale facility agreement and remitted the proceeds to ineligible shareholders. Additionally, we canceled each of the outstanding options to acquire ordinary shares of ABR and issued replacement options representing the right to acquire shares of our Common Stock on the basis of one replacement option for every ten existing ABR options held. We maintain an ASX listing for our CDIs, with each CDI representing 1/10th of a share of Common Stock. Holders of CDIs are able to trade their CDIs on the ASX and holders of shares of our Common Stock are able to trade their shares on Nasdaq.

Following completion of the corporate reorganization, ABR became a wholly owned subsidiary of 5E Advanced Materials, Inc.

## Fort Cady Project
In August 2025, we issued our Preliminary Feasibility Study prepared in accordance with Regulation S-K 1300, which focused on Phase 1 development of our Fort Cady Project to develop a 130,000 short ton per annum boric acid plant. We believe the PFS demonstrates a world-class resource and reserve, management's firm understanding and direction for the business, which can position the company to achieve profitability, generate cash flow, and reduce risk.

Due to the current favorable market backdrop and growing importance of critical materials, we continue to focus primarily on further developing our Project by working towards commercialization and building a commercial-scale facility for the extraction of boric acid, with the production of calcium chloride and gypsum as valuable co-products. A focus on boron extraction and related end markets is aligned with our mission to become a global leader in enabling industries addressing decarbonization, food security, national defense and production of domestic supply and our focus on high value in use materials and applications.

The PFS was based upon converting approximately 41% of our total resource and established approximately 5.3 million short tons of boric acid reserves with an average grade of 8.03% (B2O3) and an initial 39.5 year life of mine utilizing an in-situ leaching ("ISL") mining method. The PFS allows for optionality for future expansion phases to develop the remaining portions of our total resource, optionality for economically accretive byproducts, and future endeavors into value added advanced boron derivatives.

The financial model for the economic analysis included in the PFS was based upon a third-party preliminary market study which evaluated future supply and demand thematics for the boric acid market, as well as capital estimates developed by our EPC firm, Fluor and Miocene, Inc. ("Miocene"). The PFS included a capital estimate of approximately $367 million, a 15% contingency of approximately $55 million, and owner's costs of approximately $13 million, for an aggregate capital estimate of approximately $435 million. The capital estimate includes the anticipated costs for a natural gas Combined Heat & Power ("CHP") COGEN facility that will power Phase 1 of the Project.

------

We will continue to operate the SSF while we stage gate to FEL-3 engineering for Phase 1 of the commercial-scale complex. FEL-3 engineering is expected to provide the necessary estimates to publish a final feasibility study and, assuming the financing is secured, a final investment and construction decision for Phase 1 of the proposed commercial-scale complex. Based upon progress to date, we are now targeting to reach initial commercial production from Phase 1 in the second-half of calendar year 2028.

## Competition
The mining industry is highly competitive. According to the preliminary market study prepared by Kline & Company, Inc., there were two major competitors in the borates industry, Rio Tinto Borates ("RTB") and Eti Maden, the latter of which is owned by the Turkish government. If we are successful in bringing the Project into production, we will be competing with those two large competitors in the borates industry, one global mining conglomerate and one state-owned enterprise, each of which we believe are generally well-funded and established. We, therefore, may be at a significant disadvantage in the course of obtaining materials, supplies, labor and equipment from time to time. Additionally, we are, and expect to continue to be, an insignificant participant in the business of mining exploration and development for the foreseeable future. According to Global Market Insights, together they supplied approximately 85% of global boron demand which has led to a global duopoly, with Eti Maden alone having supplied approximately 60% of the world's recent demand.

When the Project is successfully developed and commercialized, the primary factors that we will be competing upon include, without limitation, the amount and quality of our material resources and reserves, the pricing of our products, and the quality of our customer support and service. Furthermore, prospective customers may consider additional factors such as the geographic location of our operations and the reputation of our business when compared to our competitors.

## Customers
Because we have not yet begun large-scale production of mineral products, we currently do not have any binding supply agreements with customers. During July 2024, we sent out our first samples of boric acid produced at the SSF to potential customers, and as of September 2025, we were aware of approximately 15 customers in 8 diverse market segments who had successfully qualified our boric acid through a combination of laboratory evaluation, field trials and truckload-scale shipments. We believe that the progress observed in our customer qualification efforts will facilitate discussions with stakeholders about securing commercial contracts for our future products.

## Governmental Regulation
We are subject to numerous and extensive federal, state and local laws, regulations, permits and other legal requirements applicable to the mining and mineral processing industry, including those pertaining to employee health and safety, air emissions, water usage, wastewater and stormwater discharges, air quality standards, greenhouse gas emissions, waste management, plant and wildlife protection, handling and disposal of hazardous and radioactive substances, remediation of soil and groundwater contamination, land use, reclamation and restoration of properties, the discharge of materials into the environment and groundwater quality and availability. Our business may be affected by varying degrees of government regulation such as restrictions on production, price controls, tax increases, expropriation of property, environmental and pollution controls or changes in conditions under which minerals may be marketed. An excess supply of certain minerals may exist from time to time due to lack of markets, restrictions on exports, and numerous factors beyond our control. These factors include market fluctuations and government regulations relating to prices, taxes, royalties, allowable production and importing and exporting minerals. These laws, regulations, permits and legal requirements have had, and will continue to have, a significant effect on our results of operations, earnings and competitive position.

Federal legislation and implementing regulations adopted and administered by the EPA, the Bureau of Land Management (the "BLM"), the Fish and Wildlife Service, including legislation such as the federal Clean Water Act ("CWA"), the Safe Drinking Water Act (the "SDWA"), the Clean Air Act, as amended (the "CAA"), the National Environmental Policy Act (the "NEPA"), the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 ("CERCLA"), and the Resource Conservation and Recovery Act (the "RCRA"), have a direct bearing on our proposed solution mining and processing operations. These federal initiatives are often administered and enforced through state agencies operating under parallel state statutes and regulations.

CERCLA, and comparable state statutes, impose strict, joint and several liability on current and former owners and operators of sites and on persons who disposed of or arranged for the disposal of hazardous substances found at such sites. It is not uncommon for the government to file claims requiring clean-up actions, demands for reimbursement for government-incurred clean-up costs, or natural resource damages, or for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by hazardous substances released into the environment. The RCRA, and comparable state statutes, govern the disposal of solid waste and hazardous waste and authorize the imposition of substantial fines and penalties for noncompliance, as well

------

as requirements for corrective actions. The CERCLA, RCRA, and comparable state statutes can impose liability for clean-up of sites and disposal of substances found on exploration, mining and processing sites long after activities on such sites have been completed.

The CAA restricts the emission of air pollutants from many sources, including processing activities. Any future processing operations by us may produce air emissions, including fugitive dust and other air pollutants from stationary equipment, storage facilities and the use of mobile sources such as trucks and heavy construction equipment, which are subject to review, monitoring and/or control requirements under the CAA and state air quality laws, as administered by the Mojave Desert Air Quality Management District ("MDAQCD"). New equipment and facilities are required to obtain permits before work and operations can begin. Once constructed or obtained, we may need to incur additional capital costs to ensure such facilities and equipment remain in compliance with applicable rules and regulations. In addition, permitting rules do impose limitations on our estimated production levels or result in additional capital expenditures in order to comply with the rules. We have received Authorization to Construct ("ATC") air permits for the SSF and will require ATC air permits for the equipment for the large-scale facility once FEL-3 engineering is complete.

The CWA, and comparable state statutes, imposes restrictions and controls on the discharge of pollutants into waters of the United States. The discharge of pollutants into regulated waters is prohibited, except in accordance with the terms of a permit issued by the EPA or an analogous state agency. We received a Waste Discharge Requirements ("WDR") order from the Lahontan Regional Water Quality Control Board (the "LRWQCB") in 1988 and remain in compliance with the permit conditions. The LRWQCB regulates surface activities, such as ponds, that have the potential to allow process solutions to leak into the subsurface. A Final Permanent Closure Plan has been approved by the LRWQCB for closure of the existing impoundments. Closure of the ponds and 1988 WDR is expected to be finalized later in 2025 or 2026. The current commercial design includes approximately 37 acres of evaporation ponds for the purpose of removing sodium and calcium from the back end of the processing plant. We will apply for a new or amended WDR order from LRWQCB as part of the development activities.

The CWA regulates storm water from facilities and generally requires a storm water discharge permit. The Project is located within a closed basin; therefore, the stormwater regulations do not apply either during construction or operations. We have requested and received a Notice of Non-Applicability ("NONA") from the LRWQCB. The CWA and comparable state statutes provide for civil, criminal and administrative penalties for unauthorized discharges of pollutants and impose liability on parties responsible for those discharges for the costs of cleaning up any environmental damage caused by the release and for natural resource damages resulting from the release.

The SDWA and the Underground Injection Control ("UIC") program promulgated thereunder, regulate the drilling and operation of subsurface injection wells. The EPA directly administers the UIC program in California. The program requires that a Class III UIC Solution Mining Permit be obtained before drilling an injection-recovery well. We have obtained a Class III UIC Permit to construct and operate a borate solution mine, with approval and bonding for our injection-recovery and water monitoring wells. During November 2023, the EPA provided authorization to begin in-situ mining operations pursuant to our Class III UIC permit. We expect that the EPA will grant authorization for additional wells as requested subject to an increase of the reclamation bonding amount. Violation of the Class III UIC Permit conditions, the SDWA and related UIC regulations and/or contamination of groundwater by mining related activities may result in fines, penalties, and remediation costs, among other sanctions and liabilities under the SWDA and state analogs. In addition, third party claims may be filed by landowners and other parties claiming damages for alternative water supplies, property damages, and bodily injury.

The Federal Land Policy Management Act (the "FLPMA") governs the way in which public lands administered by the BLM are managed. The General Mining Law of 1872 and the FLPMA authorize U.S. citizens to locate mining claims on federal lands open to mineral entry. Borates are a locatable mineral, and locatable mineral deposits within mining claims such as the Project may be developed, extracted and processed under a Plan of Operations approved by the BLM. The NEPA requires a review of all projects proposed to occur on public lands.

The NEPA and comparable state statute, California Environmental Quality Act ("CEQA") requires federal agencies to integrate environmental considerations into their decision-making processes by evaluating the environmental impacts of their proposed actions, including issuance of permits to mining facilities, and assessing alternatives to those actions. The Barstow Office of the BLM issued a Record of Decision ("ROD") for the Environmental Impact Statement ("EIS") in 1994. The existing ROD does not have an expiration date, and minor modifications may be required in the future, but are not required to begin operating.

Solution mining does not meet the definition of a mine under the Federal Mine Safety and Health Act of 1977, as amended by the Mine Improvement and New Emergency Response Act of 2006. Solution mining and processing activities are covered by the regulations adopted by the California Occupational Safety and Health Administration ("CalOSHA"). Therefore, our proposed operations will need to comply with the CalOSHA regulations and standards, including development of Safe Operating Procedures and training of personnel. At this time, it is not possible to predict the full effect that new or proposed statutes, regulations and policies

------

will have on our operating costs, but any expansion of existing regulations, or making such regulations more stringent may have a negative impact on the profitability of the operations.

When operational, the Project will be required to maintain a comprehensive safety program. Employees and contractors will be required to complete initial training, as well as attend annual refresher sessions, which cover potential hazards that may be present at the facility. Workers at the facility will be entitled to compensation for any work-related injuries. The State of California may consider changes in workers' compensation laws from time-to-time. Our costs will vary based on the number of accidents that occur at the Project and the costs of addressing such claims. We are and will be required to maintain insurance under various state workers' compensation programs under the statutory limits for the current and proposed operations at the Project and the offices in California.

We generally are required to mitigate long-term environmental impacts by stabilizing, contouring, re-sloping, and revegetating various portions of a site after well-field and processing operations are completed as well as plugging and abandoning injection recovery, water monitoring and exploration drilling holes. Comprehensive environmental protection and reclamation standards must be met during the course of, and upon completion of, mining activities, and any failure to meet such standards may subject us to fines, penalties or other sanctions. Reclamation efforts will be conducted in accordance with detailed plans, which are reviewed and approved by the EPA, BLM, LRWQCB, and San Bernardino County on a regular basis. We currently have reclamation obligations and we have arranged a surety bond and pledged certificates of deposits for reclamation with the State and Federal regulatory agencies. At this time, land disturbance certificate of deposits for approximately $319 thousand are in place with the County of San Bernardino, and a fully collateralized surety bond for approximately $1.2 million are in place for EPA reclamation.

We may be required to obtain new permits and permit modifications, including air, UIC permit, construction and occupancy permits issued by the San Bernardino County, California government, to complete our development plans. To obtain, maintain and renew these and other environmental permits and perform any required monitoring activities, we may be required to conduct environmental studies and collect and present to governmental authorities data pertaining to the potential impact that the current development plan or future operations may have upon the environment.

Environmental, safety and other laws and regulations continue to evolve which may cause us to meet stricter standards and give rise to greater enforcement, result in increased fines and penalties for noncompliance, and result in a heightened degree of responsibility for us and our officers, directors and employees. Future laws, regulations, permits or legal requirements, as well as the interpretation or enforcement of existing requirements, may require substantial increases in capital or operating costs to achieve and maintain compliance or otherwise delay, limit or prohibit our development plans and future operations, or other restrictions upon, our development plans or future operations or result in the imposition of fines and penalties for failure to comply.

Complying with these regulations is complicated and requires significant attention and resources. Our employees and retained consultants have a significant amount of experience working with various federal, state and local authorities to address compliance with such laws, regulations and permits. However, we cannot be sure that at all times we have been or will be in compliance with such requirements. We expect to continue to incur significant sums for ongoing regulatory expenditures, including salaries, and the costs for monitoring, compliance, remediation, reporting, pollution control equipment and permitting. In addition, we plan to invest significant capital to develop infrastructure to ensure it operates in a safe and environmentally sustainable manner.

We are not aware of any probable government regulations that would materially impact us at this time, however there can be no assurance that regulations may not arise in the future that may have a negative effect on our results of operations, earnings and competitive position.

## Dependence on Key Vendors, Suppliers and Global Supply Chain
Construction of an in-situ leaching mining operation and processing plant at the Project will require local and regional resources of contractors, construction materials, energy resources, employees, and housing for employees. The Project has good access to Interstate-40 ("I-40"), which connects it to numerous sizable communities between Barstow and the greater Los Angeles area which we believe can offer access to transportation, construction materials, labor, and housing. The Project currently has limited electrical service sufficient for the mine office, storage facilities and operation of the SSF, but will require an upgrade for our proposed commercial-scale facility and complex and wellfield facilities, or the installation of a natural gas CHP COGEN facility, as currently contemplated in our PFS. An electrical transmission corridor operated by Southern Cal Edison ("SCE") extends north-eastward through the eastern part of the Project. The boiler for the SSF operates on liquid natural gas. Currently no natural gas connects to the Project, but we have a proposal from a major U.S. interstate natural gas transmission system operator to connect to the Mojave Pipeline. Two other natural gas transmission lines run along I-40 near the Project. We currently have two water production wells in an aquifer within our permit boundary, but water is limited in the Mojave Desert.

------

## Employees
As of June 30, 2025, we had 35 full-time employees and no part-time employees. We expect to significantly increase the number of employees with each phase of production at the Project.

We have entered into an Alternative Work Schedule agreement (the "AWS") with certain non-exempt employees engaged with the operation of the SSF. The AWS is a contractual arrangement that provides for a work schedule that varies from the standard eight hours per day, five days per work week schedule in favor of a 12-hour alternating day and night shift plan that allow us to better operate the SSF. Under the AWS, employees are entitled to overtime pay if they work beyond the established alternative workweek schedule. The AWS is terminable at our discretion at any point in time but requires two-thirds of affected employees to affirmatively vote for its termination.

We use the services of independent contractors, consultants and firms to perform various professional services, including legal, environmental, commercial, investor relations, accounting and tax services, construction, geological, exploration and drilling operation services, among others.

## Intellectual Property
We have no material patents, trademarks, licenses, franchises, concessions or royalty agreements.

## Exploration
In July 2021, we purchased an additional three parcels of land and minerals, and our deposit is open to exploration on the southern side. The end of the deposit on the northwestern side has been clearly defined. We expect the southern side to become an exploration target to support proposed resource expansion drilling activities. An exploration target is a statement or estimate of the exploration potential of a mineral deposit in a defined geological setting where the statement or estimate, quoted as a range of tons and range of grade (or quality), relates to mineralization for which there has been insufficient exploration to estimate a mineral resource.

To the west of our real property are the patented and unpatented lands of a hectorite mining company as well as public lands managed by the BLM. Surface lands of both the hectorite mining company and the BLM land are included within our permitted boundaries. While the hectorite mining company has placer claims over our deposit, we have staked, filed, and recorded lode claims for the deposit. We have completed extensive diligence with third-party geologists, counsel, and mineral experts and we believe that since colemanite is a mudstone, the appropriate claim to establish mineral tenure is a lode claim. The mineral tenure established by these lode claims is not yet included in our PFS mineral resource statement and is expected to significantly increase the resource. We expect to include these resources in our next Technical Report Summary which is anticipated after the completion of FEL-3.

## Seasonality
We have no properties that are subject to material restrictions on its operations due to seasonality. However, we note that given the Project's location in the Mojave Desert, the site may be impacted by extreme heat in the summer season. In addition, the desert terrain of the Project does not adequately absorb water and is subject to flash flooding in the instance of significant rain.

## Corporate Office
Our principal executive offices are located at 9329 Mariposa Road, Suite 210, Hesperia, California 92344. Our telephone number is +1 (442) 221-0225.

## Properties
***Fort Cady Project (AKA 5E Boron Americas Project)***

The Project is located in the Mojave Desert region in the high desert in eastern San Bernardino County, California, approximately 36 miles east of Barstow, near the town of Newberry Springs and two miles south of I-40. The Project lies approximately 118 miles northeast of Los Angeles, California, or approximately half-way between Los Angeles and Las Vegas, Nevada. Access to the Project is eastbound from Barstow on I-40 to the exit for Hector Road. From the Hector Road exit, travel

------

continues south to the National Trails Highway, then east approximately one mile to County Road 20796, then south for 2.2 miles on County Road 20796 to an unnamed dirt road bearing east for another 1.1 miles to the mine office and plant site at the Project.

The Project area operates with electricity and is well served by other infrastructure, including I-40 and the main Burlington Northern Santa Fe ("BNSF") rail line that runs from Chicago, Illinois to Los Angeles, California running immediately north alongside I-40. There are three main natural gas transmission lines along the I-40. The two southern transmission lines are owned and operated by SCE, while the northern transmission line is owned and operated by Kinder Morgan. The port of Los Angeles, Long Beach and San Diego are all within a half-day drive from the Project on major highways. The Project will likely attract personnel from the Barstow-Victorville area.

The Project deposit is in a prospective area for borate and lithium mineralization and is fundamental to our strategy to become a globally integrated supplier of borates, lithium carbonate and advanced boron derivatives. The deposit mineralization is colemanite and the Project has a similar geological setting to RTB's Boron open-pit mine and Nirma Limited's Searles Lake operations, situated approximately 75 miles west-northwest and 90 miles northwest of the Project, respectively.

![img213446086_1.jpg](img213446086_1.jpg)

*Mineral Title*

We own fee simple (private) lands in Sections 25 and 36 of Township 8 North, Range 5 East of the San Bernardino Principal Meridian. An electrical transmission corridor, operated by SCE, tracts from the northeast to the southwest through the fee lands with SCE having surface and subsurface control to a depth of 500 feet, affecting approximately 91 acres of surface lands in the two sections. While this limits surface access to the land, mineralization remains accessible as the ore body occurs at depths greater than 1,000 feet.

------

We currently hold 30 unpatented lode claims, 117 unpatented placer claims, and two unpatented millsite claims with the BLM within the U.S. Department of the Interior. Two lode claims were originally filed by Duval Corporation ("Duval") in 1978 with the other 28 lode claims filed by the Company in January and August 2025. Placer claims were filed between October 29, 2016, and February 24, 2017. A review of the BLM Mineral & Land Record System database shows claim status as filed with next assessment fees due annually on September 1.

Lastly, 272 acres of land located in Section 36 of Township 8 North, Range 5 East of the San Bernardino Principal Meridian, are split estate, with the surface estate owned by us and the mineral estate is owned by the State of California. These lands are available to us through a mineral lease from the California State Lands Commission. We own the remaining lands, with the minerals underlying the transmission line available subsurface.

*Overview of Mining Locations*![img213446086_2.jpg](img213446086_2.jpg)

*Fort Cady History* 

Discovery of the Project borate deposit occurred in 1964 when Congdon and Carey Minerals Exploration Company found several zones of colemanite, a calcium borate mineral, between the depths of 1,330 feet to 1,570 feet below ground surface in Section 26. In September 1977, Duval initiated land acquisition and exploration activities near Hector, California. By March 1981, Duval had completed 34 exploration holes, plus one potential water well. After evaluation of the exploration holes, Duval considered several mining methods. Subsequent studies and tests performed by Duval indicated that in-situ mining technology was feasible.

Duval commenced limited testing and pilot-scale solution mining operation in June 1981. Mountain States Mineral Enterprises, Inc. ("MSME") purchased the Project from Duval in 1985. In July 1986, tests were initiated by MSME, where dilute hydrochloric acid solution was injected into the ore body. The acid dissolved the colemanite and was then withdrawn from the same well. Between 1981

------

and 2001, the various owners of the Project drilled an additional 17 wells, which were used for a series of injection testing and pilot-scale operations.

An additional phase of pilot plant operations was conducted between 1987 and 1988. The test results were positive; thus, the Project was viewed as commercially viable. MSME sold the Project to Fort Cady Mineral Corporation ("FCMC") in 1989. In preparation for the permitting process, feasibility studies, detailed engineering and test work were completed by FCMC.

In 1990, a Plan of Operations ("PoO") was submitted to the BLM and a Mining Conditional Use Permit and Reclamation Plan was submitted to San Bernardino County, which triggered environmental review under NEPA and CEQA. With the Project located on both public and private lands, the public lands are managed by the BLM in accordance with Surface Management Regulations of the Federal Land Policy and Management Act and federal environmental laws, and the private lands administered by San Bernardino County Land Use Services ("SBC-LUS") in accordance with the California Surface Mining and Reclamation Act, the County Development Code and state environmental laws.

Based upon the activities described in the PoO, under the NEPA regulations, the BLM determined that an EIS was required while under CEQA, SBC-LUS determined that an Environmental Impact Report ("EIR") was required. Under a Memorandum of Understanding, the two agencies completed a joint EIS and EIR to satisfy their environmental review requirements under NEPA and CEQA, respectively. The EIS and EIR process followed clearly defined requirements for public participation in studies, such as threatened and endangered species, cultural resources, light, noise, and impacts to local communities. The studies were completed, as was the public participation process, which resulted in a 1994 ROD from the BLM that approved the PoO and approval of the Mining Conditional Use Permit and Reclamation Plan from the SBC-LUS.

A second phase of pilot plant operations occurred between 1996 and 2001, during which approximately 2,200 tons of a synthetic colemanite product, marketed as CadyCal 100, were produced. Commercial-scale operations were not commissioned due to low product prices and other priorities of the controlling entity. For many years, boron was used in traditional applications such as cleaning supplies and ceramics, which did not formulate into a strong pull-side demand investment thesis where pricing justified further development of the Project.

In 2017, a group of Australian investors identified the Project and formed the investment thesis that the boron market had similar dynamics to the lithium market a decade earlier. Like the lithium market ten years prior, the market was dominated by a few companies with a compelling pull-side demand growth story fueled by future-facing applications targeting decarbonization and critical materials. Prior to lithium-ion batteries and electric vehicles, lithium was used in traditional everyday applications like boron's use in recent years. As a result of the investment thesis that boron is expected to experience a supply deficit relative to demand, the group of Australian investors formed ABR and issued shares to Atlas Precious Metals in exchange for Fort Cady (California) Corporation, the entity holding the permits, mineral and property rights of the Project. In 2017, ABR underwent an initial public offering on the ASX and progressed exploration and development of the Project. In September 2021, ABR created a subsidiary, 5E Advanced Materials, Inc., and through the Scheme, reorganized the Company which placed the Company at the top of the corporate structure. Upon 5E Advanced Materials, Inc. becoming the parent company of the organization, in March 2022, we direct listed on the Nasdaq and became an issuer with the U.S. Securities and Exchange Commission.

In total, we have spent in excess of $156 million on the Project thus far, including resource drilling, monitoring wells, metallurgical test works, well injection tests, permitting activities, construction and operation of the SSF, pilot-scale test works and engineering of the commercial-scale facility.

*Access and Infrastructure*

We continue to develop operating infrastructure for the Project in support of extraction and processing activities. A manned gate is located on the Project access road and provides required site-specific safety briefings and monitors personnel entry and exit to the site. Personnel are predominantly sourced from the surrounding area including Barstow, California and Victorville, California.

The BNSF rail line from Las Vegas, Nevada to Los Angeles, California runs parallel to I-40 and adjacent to the Project. A rail loadout is located approximately 1.2 miles north of the National Trails Highway on a road that bears north and located 0.4 miles west of San Bernardino County Road 20796. San Bernardino County operates six general aviation airports with the closest airport to the Project being the Barstow-Daggett Airport located approximately 23 miles west of the Project off the National Trails Highway. Commercial flight service is available through five airports in the greater Los Angeles area and in Las Vegas, Nevada. A dedicated cargo service airport is located approximately 65 miles southwest of the Project.

The construction of the SSF was performed by a construction contractor with additional local resources supporting construction contracting, construction materials, energy sources, employees, and housing. The Project has good access to I-40 which connects it to

------

numerous sizable communities between Barstow, California and the greater Los Angeles area offering excellent access to transportation, construction materials, labor, and housing. The Project was successful in removing natural gas generators from the facility and is currently supplied by approximately one mega watt of shore power that is sufficient for mine office, storage facilities on site, and the operation of the SSF. An electrical transmission corridor operated by SCE extends northeastward through the eastern part of the Project. The Project has two water wells located nearby to support in-situ leaching operations where unpatented millsite claims are filed. Currently there is no natural gas connects to the Project, but we have a proposal from a major U.S. interstate natural gas transmission system operator to connect to the Mojave Pipeline. Two other natural gas transmission lines run along I-40 near the Project.

The plant site currently has a 1,600 square foot mine office building, a control room, storage buildings, an analytical laboratory, an approximately 20-acre production facility (the SSF), four injection/recovery wells, and an intended gypsum storage area occupying 17 acres. Gypsum is a byproduct of past pilot plant production and is intended, along with calcium chloride, to be a future co-product that can be sold to the regional market.

*Project Permits and Reclamation Requirements*

We currently have the following Project permits in place:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.The MDAQCD has issued operating permits for the SSF and the permits are renewed annually. After front-end engineering and design and during detail design of the proposed commercial-scale facility, and once we have determined each original equipment manufacturer for major pieces of equipment and based on the specification sheets for each piece of equipment, ATC permits for the proposed commercial-scale facility will be provided to MDAQMD for approval. It is expected that the issuance of the ATCs will require that the existing operating permits for the SSF be closed. The ATC permits for the proposed commercial-scale facility must meet National Ambient Air Quality Standards ("NAAQS") and MDAQMD requirements (Air Resources Board, MDAQMD, and EPA).

There is no reclamation or closure requirement under MDAQMD.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.The LRWQC issued the current WDR in 1988. The WDRs regulate activities in the existing surface impoundments, which were used in the 1990's to produce CadyCal and are no longer being used. We remain compliant with the permit by complying with the monitoring requirements and submitting quarterly reports. A Final Permanent Closure Plan has been approved by the LRWQCB for closure of the existing impoundments. Closure of the ponds and 1988 WDRs is expected to be finalized later in 2025 or 2026. The current proposed commercial-scale facility design includes approximately 37 acres of evaporation ponds for the purpose of removing sodium and calcium from the back end of the processing plant. We will apply for a new or amended WDRs order from LRWQCB for the proposed commercial-scale facility.

There is an existing reclamation and closure requirement approved by LRWQCB. The bond amount to close the ponds is included in the SBC – LUS Financial Assurance Cost Estimate ("FACE"), discussed below. This is currently a certificate of deposit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.The LRWQCB also issued a NONA, verifying that the Project does not require a stormwater permit for approved construction and operations activities. The NONA was issued as the Project is located in a closed basin with no stormwater discharge.

There is no reclamation or bonding requirement associated with the NONA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.SBC-LUS issued the Mining Conditional Use Permit and Reclamation Plan in 1994, based upon the 1990 application and ensuing EIR. The Reclamation Plan was amended, and the permit was modified in 2019 to address changes such as relocation of the processing plant and additional water related infrastructure. Ground use is regulated in accordance with applicable state law. The Mining Conditional Use Permit and Reclamation Plan includes Conditions of Approval for engineering and planning related activities, as well as requirements to avoid impacts to desert tortoises. The permitted production throughput under the Mining Conditional Use Permit is 90,000 short tons of boron oxide or boron oxide equivalent.

We maintain a certificate of deposit with the California State Mining and Reclamation Agency, as administered by SBC-LUS. The FACE is updated annually. The FACE includes demolition of all existing structures, regrading, and revegetation of all disturbance on private lands. This bond also includes plugging and abandonment of all wells located outside the EPA UIC purview.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.The BLM issued a ROD in 1994, establishing the EIS boundary. The ROD authorizes mining of borates. The ROD also has requirements for our activities to eliminate adverse impacts to desert tortoises and cultural resources.

Reclamation and land disturbance for BLM is currently included with the FACE on file with the County and bonded in certificate of deposit with the California Division of Mine Reclamation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.The EPA retains primacy for Class 3 solution mining UIC permits in the State of California. The EPA issued the UIC permit for the Project in August 2020. The permit defines the Area of Review ("AOR") boundary. All subsurface solution mining activities, including monitoring wells and injection wells, are located within the AOR boundary. The EPA approved mining operations in November 2023.

In accordance with the permit conditions, we have installed five upgradient and four downgradient monitor wells for the initial mining block. As a condition to receive final approval in November 2023, the EPA required modification to the permit and the installation of three additional water monitoring wells. The permit was modified in June 2024, and the three additional wells were installed in fall 2024.

We installed four Injection/Recovery Wells ("IR Wells") and subsequently modified the permit to include horizontal wells. In July 2025, two of the IR Wells were converted from vertical wells to horizontal-side tracks where each well extends approximately 1,500 ft laterally. We expect to submit a final mine plan to the EPA for review based on the performance of the horizontal-side track IR Wells.

We have submitted and maintains a fully collateralized surety bond with the EPA for plugging and abandonment of all wells within the EPA AOR boundary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.Additional environmental permitting that will likely be required for the proposed commercial-scale facility includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.The California Unified Control Act/Agency has primacy over EPA's Tier II reporting requirements. The Hazardous Material Business Plan has been submitted for construction related activities and will be updated with processing related chemicals that are expected to be utilized to operate the proposed commercial-scale facility. Such updates will require additional approvals.

*SSF Update*

In April 2024, we commenced operation of the SSF, an above ground chemical plant designed to refine borates, which has served as a foundation for the design, engineering, and cost optimization for our proposed commercial-scale facility and complex, as well as serving as the source of product for our customer qualification and offtake agreement efforts. The SSF is an essential step in the overall Project development plan and serves as our current extraction and processing facility to demonstrate product development and design. Shortly after we began to process the PLS at the SSF we produced our first batch of boric acid. During July 2024, we sent out our first samples of boric acid produced at the SSF to potential customers, and during April 2025, we were notified by a leading global specialty glass manufacturer that they had successfully produced specialty glass utilizing our boric acid. As of September 2025, we were aware of approximately 14 customers in 8 diverse market segments who had successfully qualified our boric acid through a combination of laboratory evaluation, field trials and truckload-scale shipments. As part of ongoing customer qualification program, we plan to deliver larger volumes of boric acid from the SSF to customer production facilities for product validation. We believe that the progress observed in our customer qualification efforts will facilitate discussions with stakeholders about funding options for Phase 1 of the commercial facility and securing commercial contracts for our future products. The SSF currently produces approximately one short ton per day of boric acid. We plan to continue to run the SSF to refine our operations, more effectively optimize detail engineering of our proposed commercial-scale facility, and to produce boric acid for customer qualification.

*Preliminary Feasibility Study*

In August 2025, we issued our PFS that was prepared in accordance with Regulation S-K 1300, which focused on Phase 1 development of our Fort Cady Project to develop a 130,000 short ton per annum boric acid plant. We believe the PFS demonstrates a world-class resource and reserve, management's firm understanding and direction for the business, which can position the company to achieve profitability, generate cash flow, and reduce risk. The PFS includes a revised mineral resource estimate and mineral reserve statement for boric acid, estimates for capital costs and operating expenses, and a bottoms-up economic analysis of the first commercial phase of the Project. The financial model for the economic analysis includes third-party preliminary market studies and independent pricing forecasts for boric acid, calcium chloride and gypsum. The report was prepared by qualified persons ("QP" as defined in S-K 1300) including Company management and third-party independent companies Miocene, Fluor, Geomega, Inc., and

------

Escalante Geological Services, LLC ("Escalante"). All QPs have the necessary experience per Regulation S-K 1300 and material assumptions and information pertaining to the disclosure of our mineral resources, including material assumptions relating to all modifying factors, price estimates, and scientific and technical information, as described in the PFS, and remain current as of the date of this report.

The PFS converted approximately 41% of our total resource and established approximately 5.3 million short tons of boric acid reserves with an average grade of 8.03% (B2O3) and an initial 39.5 year life of mine utilizing an ISL mining method. The PFS allows for optionality for future expansion phases to develop and convert the remaining portions of our total resource into reserves and future endeavors into value added advanced boron derivatives and economically accretive byproducts.

The financial model for the economic analysis included in the PFS was based upon a third-party preliminary market study which evaluated future supply and demand thematics for the boric acid market, as well as capital estimates developed by our EPC firm, Fluor and Miocene. The PFS included a capital estimate of approximately $367 million, a 15% contingency of approximately $55 million, and owner's costs of approximately $13 million, for an aggregate capital estimate of approximately $435 million. The capital estimate includes the anticipated costs for a natural gas CHP COGEN facility that will power Phase 1 of the Project.

We will continue to operate the SSF while we stage gate to FEL-3 engineering for Phase 1 of the commercial-scale complex

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•FEL-3 engineering is expected to provide the necessary estimates to publish a final feasibility study and a final investment and construction decision for Phase 1 of the proposed commercial-scale complex. Based upon progress to date, we are now targeting to reach initial commercial production from Phase 1 in the second half of calendar year 2028.

*Plan of Operations*

Upon successful development of the Project, we expect to mine and process colemanite to produce borates, calcium chloride and gypsum. The borates produced are planned to be further produced into second, third and fourth boron derivatives. Initially, we expect to derive revenue principally from the sale of boric acid, calcium chloride, and gypsum. As our advanced boron materials strategy develops, we intend to produce revenue from advanced boron materials further enabling decarbonization, energy, food security, and defense applications.

The Project deposit is planned to be mined via ISL mining to recover leached solution from the mineralized horizons, which is a technique that has been utilized for several decades in the production of uranium, salt, bromine, potash and soda ash. The use of in-situ technology for boron extraction was developed at the Project property in the 1980s. In-situ solution mining depends on void spaces, porosity, permeability, ore zone thickness, transmissivity, storage coefficient, piezometric surface, and hydraulic gradient as well as reaction and extraction method efficiencies. There are various ways of developing the wellfield for in-situ leaching, including a "push-pull" mechanism where wells function as both injection and recovery wells; line drive; and multiple spot patterns. We plan to develop the Project utilizing a horizontal well development strategy, and this strategy was incorporated into the assumptions for the PFS. During July 2025, we converted two of our existing vertical IR Wells into horizontal wells by drilling 1,500-foot laterals from each well, placing the wellbores in high-grade colemanite zones of the deposit. We plan to operate these horizontal wells for the next several months to optimize the wellfield design and operational methods for the proposed commercial-scale facility.

The recovery of boron from colemanite is currently occurring through ISL mining and boric acid is being produced at the SSF. The in-situ mining method includes injecting a weak hydrochloric acid ("HCl") solution (containing <5% HCl in substantially recycled water solution with regenerated HCl) through wells drilled into the colemanite ore body. The injected acid remains in the formation for a limited period of time to allow reaction with the alkaline ore body and leach the colemanite ore.

The extracted solution is pumped to the processing facility where leach solution is crystallized to produce boric acid. The crystallized boric acid is dried, sized, and bagged as final product. Other boron products are expected to be prepared for market, as required, by end-use customers. Calcium is expected to be recovered from the remaining solution after boric acid processing to produce either gypsum or calcium chloride with the final solution being substantially recycled back into the resource deposit. Within the processing facility, some HCl is regenerated from the gypsum precipitation process as a result of the sulfuric acid acidification of the process recycle stream. The weak HCl solution is combined with recycled water to produce the make-up solution for reinjection into the formation. The process operates a zero liquid discharge evaporator and produces no liquid waste.

***Mineral Resource Estimate***

In March 2025, Mr. Steven Kerr of Escalante completed and updated resource estimate for the Project. The March 2025 resource estimate updated the prior estimate from 2021, and incorporated data from three additional bore holes and the acquisition of additional mineral tenure for the Project which occurred during the intervening period. That report identified a measured plus

------

indicated mineral resource estimate of 109.13 million short tons under mineral control by the Company, containing an average grade of 7.89% B2O3 and 303 parts per million ("ppm") of lithium, using a 2.0% cut-off grade for B2O3. The mineral resource estimate also identified 3.35 million short tons of inferred resources under mineral control by the Company. Uncontrolled land (State of California Surface) contained approximately 22.36 million short tons of measured plus indicated resources and an inferred resource of 0.93 million short tons. The electrical transmission corridor operated by SCE contained 27.78 million short tons, or 25%, of the total mineral resources. While SCE maintains control of the surface and resources to a depth of 500 ft, it does not impinge on our mineral rights for colemanite which occur at depths greater than 1,000 ft. The mineral resource estimate was incorporated into our PFS, which is incorporated by reference to Exhibit 96.1 to this Annual Report on Form 10-K.

*Mineral Resources*

Regulation S-K 1300 defines a "mineral resource" as a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, considering relevant factors such as cut-off grade, likely mining dimensions, location, or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled.

A "measured mineral resource" is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors, as defined in this section, in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve.

An "indicated mineral resource" is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve.

An "inferred mineral resource" is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource considered when assessing the economic viability of a mining project must be presented along with economic viability excluding inferred resources and may not be converted to a mineral reserve.

*Resource Assumptions*

Key assumptions used in the resource estimate include: mineralized horizons exhibit lateral continuity that will support mining using in-situ leaching mining methods, mineralized horizons are not disrupted by structural or stratigraphic features that could limit mining, there is reasonable continuity of colemanite mineralization throughout the deposit, and there is adequate exploration data to support estimation of resources.

*Resource Methodology*

The database used for resource estimation includes 52 core holes and three rotary holes for a total of 55 bore holes. Thirty of the core holes were completed by Duval between 1979 and 1981. We completed 14 core holes in 2017 and another core hole in 2022. In 2024, we completed three additional rotary holes as observation wells from which chip samples were collected through the mineral horizons for B2O3 and lithium analyses. The cumulative sampled length for the database is approximately 17,848 feet. The Project's exploration dataset is current as of February 12, 2025. Drilling coordinates in the database are in UTM NAD 83-11, and depths and elevations are reported in meters. Borate is listed as weight percent (%) B2O3 and lithium as ppm. The drilling database contains 5,767 analytical values for B2O3 and 5,402 analytical values for lithium.

Core recovery for the 2017 drilling program ranged from 93% to 100% with an overall average of 97.60%. Physical core recovery records for earlier drilling conducted by Duval and FCMC are not available, but based on missing intervals in the drilling

------

database, core recovery likely exceeded 90% in the core drilling and correlates to the 2017 drilling program. The QP has completed a thorough review and verification of the drilling database and found the database to be sufficient for resource modeling.

The QP developed a gridded geologic model of the Project using Carlson Mining™ software. The mineralization does not correlate to lithological markers as the entire sequence is predominantly lacustrine mudstone. However, detailed examination of the analytical results reveals distinct mineralized horizons. The deposit was delineated based on these patterns of mineralization into four mineralized horizons, two non-mineralized or weakly mineralized interbeds and two non-mineralized horizons bounding the deposit. The grid model was constructed across the deposit area, with a grid cell size of 50 meters by 50 meters. Grids represent the bounding elevation surfaces of key horizons, horizon thicknesses, and analytical grades. Grids representing the bounding surface elevations of the mineral horizon were interpolated through triangulation. Mineral horizon grids for thickness and analytical grades were interpolated using Ordinary Kriging ("OK") and Inverse Distance Squared ("ID2") algorithms. Mineralization is spatially defined by a resource boundary using a distance of 200 meters from the last intersection of mineralization in a drill hole and by property boundaries. Grids are masked to the outside of the resource boundary.

Using composites for each mineralized horizon, variography was successful for B2O3 grades for the Major Mineralized Horizon ("MMH"), Intermediate Mineralized Horizon ("IMH"), and the Lower Mineralized Horizon ("LMH"). Variogram modeling was unsuccessful for the Upper Mineralized Horizon ("UMH") and with lithium in all horizons. Grids representing B2O3 grades for the MMH, IMH, and LMH were constructed using OK based on the constructed variograms. ID2 interpolation was used with all remaining grade grids using the same spatial limits established with the horizon grids.

*Cut-off Grade*

Cut-off grade is an economic analysis to measure cash costs (i.e., the variable cost to produce boric acid compared to the price that can be achieved in the market for the sale of boric acid). We commenced mining operations in January 2024 and began operating the SSF in April 2024. The SSF achieved a steady state of operation in the summer of 2024 and optimized mining operations by September 2024. As such, mining data from September and October 2024 have been utilized as the basis of design and further leveraged for the cut-off grade analysis. Using this data set, an in-depth assessment was performed that included an analysis of the cash costs (i.e., the variable cost to produce boric acid) and excluded book costs (i.e., depreciation) as the capital is assumed to have already been invested to build the project such that it can operate. The definition of cut-off grade for the in-situ mining operation is the point at which the Company would cease operating a particular well or in the case of a combination of wells, the wellfield. As such, cash costs are established as the basis for the analysis.

A 5.0% B2O3 cut-off grade was previously established by Duval and was carried forth by previous QPs in previous technical report summaries. An in-depth assessment of cut-off grade was undertaken in 2022 and 2023 as mass and energy balances were developed to fundamentally begin to assess economic viability of the Project. Data informing the mass and energy balances included incorporating the results of leaching tests, historical results, mining, and processing costs, as well as commodity pricing, and resulted in a 2.0% cut-off calculation.

The in-depth analysis discussed above incorporated mineralization and at what point economic extraction or boron in solution is no longer viable. The driver of this analysis focuses on three specific ratios derived from the basis of design using mining data from the periods of September and October 2024: calcium to boron, sodium to boron, and magnesium to boron. These three ratios are drivers of various costs, chemical utilizations, and byproduct production rates. For example, calcium to boron impacts sulfuric acid utilization and gypsum production compared to boric acid production. Additionally, magnesium to boron impacts lime utilization and metal salt waste production compared to boric acid production. Lastly, sodium to boron impacts HCl utilization and sodium chloride production compared to boric acid production.

The PFS incorporated the above methodology and other key assumptions that are in the financial model detailed in Section 19 of the PFS (refer to Exhibit 96.1 hereto). The sales price for boric acid has increased over the past several years and was tracking around $1,100 to $1,300 per short ton free on board ("FOB") in the spot market during June and July of 2025, and the PFS includes an assumption of $1,248 per short ton FOB when production first commences based on a preliminary market study prepared by an independent third-party. Sales prices for calcium chloride and gypsum in the PFS were similarly based upon a preliminary market study and forecasts prepared by the same independent third-party. The result of this exercise is a 2.0% financially viable driven grade cut-off, where the costs are near the forecasted price for boric acid.

*Fort Cady Mineral Resource Estimate as of March 10, 2025*

Results of the mineral resource estimation are shown in the table below, based on resource classification of the Project. The resource estimate contains a combined 109.13 million short tons of measured plus indicated resources with an average grade of 7.89%

------

B2O3 and 303 ppm lithium, using a 2.0% cut-off grade for B2O3 and no cut-off grade for lithium. The sales price for boric acid has increased over the past several years and was tracking around $1,100 to $1,300 per short ton FOB in the spot market during June and July of 2025. Our PFS estimates the FOB prices for boric acid, calcium chloride and gypsum to be $1,248, $174 and $33 per short ton, respectively, in the first year of production, based upon a preliminary market study prepared by an independent third-party, as discussed in further detail of Section 16 and 19.3.1 of our PFS filed as Exhibit 96.1 hereto. The mineral resource estimate also identifies 4.29 million short tons of total inferred resources with an average grade of 7.45% B2O3 and 310 ppm lithium. The reference point for the resource in the PFS is in-situ prior to mining losses and processing losses. The resource estimate detailed below, including all assumptions and inputs utilized to arrive at such estimate, remain reasonable and accurate as of June 30, 2025.

*Commodity Pricing Assumptions*

Our PFS includes an economic analysis, and we obtained an independent preliminary market study for boric acid, calcium chloride and gypsum. The preliminary market studies were based on 15 years of historical data and include an assessment of future supply and demand analysis as well as forecasted future price assumptions, as further detailed in Sections 16 and 19.3.1 of our PFS, which is incorporated by reference as Exhibit 96.1. Our PFS estimates the price for boric acid to be $1,248 per short ton in the initial year of commercial production, escalating to $1,364 per short ton in 2033 due to demand outpacing supply of boric acid, and then held flat when supply and demand for boric acid are expected to normalize. Our PFS estimates the price for calcium chloride and gypsum to be $174 and $33 per short ton, respectively, in the initial year of commercial production, with such prices held flat throughout the model. The price utilized in the financial model for gypsum and calcium chloride is the real price as of June 2025 as provided by the independent preliminary market study. Per the independent preliminary market study, the sales price for boric acid has increased over the past several years and was tracking around $1,100 to $1,300 per short ton FOB in the spot market during June and July of 2025 with variations driven by differing jurisdictions in the spot market. Refer to the tables below for a summary of the prices utilized in our economic analysis included in our PFS.

The PFS was prepared based primarily on information available at the time of preparation, is subject to assumptions, conditions and is qualified by various limitations. The foregoing summary description of the PFS is qualified in its entirety by reference to the full PFS, which is included as Exhibit 96.1 to this Annual Report on Form 10-K.

*Internal Controls Disclosure* 

Between September 2017 and October 2017, 14 holes for a total of 23,111 feet were completed as part of a confirmatory resource drilling program. Assay results from all 14 drill holes were used in the mineral resource estimate. There are 2,113 samples from the 2017 drilling program representing 1,713 feet of core. In conjunction with the 2017 drilling program, 29 historical drill holes completed by Duval and four holes completed by FCMC were in the mineral resource estimate. There are 3,672 samples from the historic drilling representing a cumulative total of 10,831 feet of core.

The PFS indicates that the quality assurance and quality control ("QA/QC") procedures for the Duval and FCMC drill holes are unknown, though the work products compiled during these historic drilling campaigns, suggests they were carried out by competent geologists following procedures considered standard practice at those times. Discussions held with the exploration geologist for Duval at the time of drilling and sampling indicate that Duval had internal QA/QC procedures in place to ensure that assay results were accurate. Geochemical analyses were carried out using X-Ray Fluorescence Spectrometry ("XRF"). XRF results were reportedly checked against logging and assay data.

For the database of drill holes, entire core hole sequences were sampled and dispatched by commercial carrier to the Saskatchewan Research Council ("SRC") for geochemical analysis. As part of the QA/QC procedures, internationally recognized standards, blanks and duplicates were inserted into the sample batches prior to submitting to SRC. SRC has been accredited by the Standards Council of Canada and conforms with the requirements of ISO/IEC 17025.2005. Upon receipt of samples, SRC completed an inventory of samples received, completing the chain of custody documentation, and providing a ledger system tracking samples

received and steps in process for sample preparation and analysis. Core samples and chip samples were dried in their original sample bags, then jaw crushed. A subsample was split out using a sample riffler. The subsample was then pulverized with a jaw and ring grinding mill. The grinding mill was cleaned between each sample using steel wool and compressed air or by silica sand. The resulting pulp sample was then transferred to a barcode labeled plastic vial for analysis. All samples underwent a multi-element Inductively Coupled Plasma Optical Emission Spectroscopy ("ICP-OES"), using a multi-acid digestion for a range of elements. Boron was also analyzed by ICP-OES but underwent a separate digestion where an aliquot of the sample was fused in a mixture of NaO2/NaCO3 in a muffle oven, then dissolved in deionized water, prior to analysis. Major oxides were reported in weight percent. Minor, trace, and rare earth elements were reported in ppm. The detection limit for boron was 2 ppm and 1 ppm for lithium.

For the database of drill holes, a total of 2,253 core samples and 441 control samples were submitted for multi-element analysis to SRC. We submitted control samples, in the form of certified standards, blanks and coarse duplicates (bags with sample identification supplied for SRC to make duplicate samples). In addition to these control samples, SRC also submitted their own internal control samples in the form of standards and pulp duplicates. Certified standards, prepared by the National Institute of Standards and Technology, were submitted as part of our QA/QC procedures. No two standards in any single batch submission were more than two standard deviations from the analyzed mean, implying an acceptable level of precision of SRC instrumentation. SRC assayed two different standards, for its own QA/QC protocol and the QP found that the analytical precision for analysis of both standards was reasonable, with no two standards in any single batch submission being more than two standard deviations from the analyzed mean.

Blank samples inserted consisting of non-mineralized marble. One hundred and thirty-five blank samples were submitted, all of which had assay results of less than 73 ppm boron. The level of boron detected in the blanks was likely sourced from pharmaceutical (borosilicate) glass used during sample digestion. These boron concentrations are considered immaterial in relation to the boron levels detected in the colemanite mineralization and do not appear to represent carryover contamination from sample preparation. Lithium levels in the blank samples were also at acceptable levels with the majority of assays less than 15 ppm lithium. The four highest lithium levels in the blanks immediately followed samples that contained relatively high lithium concentrations. Overall, the concentration of the primary elements of interest (boron and lithium) in the blank samples were at levels considered to be acceptable, implying a reasonable performance for sample preparation.

A total of 136 duplicate samples were submitted to the SRC. SRC composed coarse duplicate samples using a Boyd rotary splitter. There was a good correlation between original and duplicate samples with a reasonable level of precision maintained in the results.

*Comparison of Mineral Resource Estimates to Prior Year*

The technical report summary included as an exhibit to our prior year Annual Report on Form 10-K, which was estimated as of April 1, 2023 and remained valid as of June 30, 2024, reported measured, indicated and inferred mineral resources of 2.65, 3.15 and 8.17 million short tons of boric acid, respectively. The mineral resource estimate included as exhibit 96.1 to this Annual Report and summarized above, was estimated as of March 10, 2025 and remained valid as of June 30, 2025, reported measured, indicated and inferred mineral resources of 3.37, 14.18 and 0.55 million short tons of boric acid, respectively. This represents a 203% increase in combined measured and indicated resource, which is comprised of a 27% increase in measured resource, and a 350% increase in indicated resource. Inferred resource decreased 93% compared to the prior year. These year-over-year changes are ascribed to increases in mineral tenure between periods.

***Mineral Reserve Estimate***

In August 2025, Miocene completed a mineral reserve estimate for the Project. The mineral reserve estimate was developed based upon the detailed mine plan included in Section 13 of our PFS and the mineral resource estimate. Prior to August 2025, we had not yet established mineral reserves and therefore have not disclosed reserve estimates as of June 30, 2025 or 2024. Reserves point of reference is in-situ with a 2% cutoff grade established based on the analysis performed with the mineral resources cut-off grade. Our EPA UIC permit subdivides the mineralized deposit into three blocks for development. Block 1 comprises the northwestern third of the orebody, Block 2 occupies the central portion of the orebody, and Block 3 comprises the southeastern third of the orebody. The SSF currently operates in Block 2 and Block 2 is permitted for mining with sufficient resources on fee-based lands and within the power corridor operated by SCE to convert resources to reserves on an economic basis, which provides for a 39.5 years life of mine. To convert additional resources to reserves, Block 1 and Block 3 would need to be authorized by the EPA and a mine plan devised that includes this mineral tenure.

------

For economic modeling, a mine plan was designed where recovery and flow rates are sufficient to feed the chemical plant where PLS is converted to a finished refined borate product available for sale. Production output is within permitted parameters with forecasted revenue from borate sales based on a pricing forecast based on the aforementioned third-party preliminary market study.

The mine plan and wellfield optimization were based on third-party engineering work that incorporated 18 months of actual wellfield data from the SSF into the design and included a bottoms-up capital estimate. The capital estimate was derived by Fluor for the inside and outside battery limits above ground and a total capital estimate was derived and incorporated into the economic analysis. The operating costs were derived from material and energy balances provided by Fluor as well as a bottoms-up labor build for human capital requirements. The revenue and cost inputs for the economic model were on a real basis.

The August 2025 reserve estimate identified 1.35 million short tons of proven boric acid reserves, and 3.98 million short tons of probable boric reserves, containing an average grade of 8.03% B2O3 using a 2.0% cut-off grade for B2O3, consistent with the cut-off grade for the mineral resource estimate. The mineral reserve estimate was incorporated into our PFS, which is incorporated by reference to Exhibit 96.1 to this Annual Report on Form 10-K.

*Mineral Reserves*

Regulation S-K 1300 defines a "proven mineral reserve" as is the economically mineable part of a measured mineral resource and can only result from conversion of a measured mineral resource.

A "probable mineral reserve" is the economically mineable part of an indicated and, in some cases, a measured mineral resource.

*Reserve Assumptions*

Assumptions utilized for the reserve estimate were consistent with the assumptions utilized for the resource estimate, except that only measured and indicated resource included in the mine plan from fee-based lands and the power corridor operated by SCE were included in the resource base (representing approximately 80% of our fee-based lands and 5% of the power corridor). The economic assessment that supports the recognition of reserves was based on a 130,000 short ton per year boric acid production plant, a capital cost estimate for Phase 1 of the Project of approximately $435 million, in-situ leading mining operation delivering 10.2% boric acid in solution (head grade), by weight, to an above ground processing plant; the aforementioned commodity price assumptions; cash operating costs of approximately $563 per ton of boric acid produced and a 7% discount rate. Additional assumptions included performing a tradeoff analysis based on actual vertical well performance relative to expected horizontal well performance whereby horizontal well performance is expected to outperform vertical wells, the chemical plant is designed to yield 95.1% boric acid yield, leaching efficiency is assumed to be 81.9% based on leach testing, and mining efficiency was 95% based on the Company's July 2025 horizontal drilling program.

The reserve estimate is subject to potential change based on changes to the forward-looking cost and revenue assumptions. It is assumed that we will produce and sell borates to customers once the proposed commercial-scale facility is constructed, commissioned, and in operation. Full extraction of this reserve is dependent upon the modification of the Company's UIC permit to include the final mine plan based on the learnings obtained from the Company's horizontal wells that were drilled in July 2025. We obtained a minor modification and authorization to drill the horizontal and sidetrack program in July 2025, and it is our expectation that we will be successful in modifying the UIC permit. The evaporation ponds incorporated into the design of the proposed commercial-scale facility and placed on our fee-based land require a WDR with the LRWQCB. We have an existing WDR for evaporation ponds and we expect to obtain the WDR for the evaporation ponds to remove calcium and sodium.

We do not believe that there are other existing environmental, permitting, legal, socio-economic, marketing, political, or other factors that might materially affect the in-situ mineral reserve estimate.

***Salt Wells Projects***

In addition to the Project, we had an Earn-in Agreement with Great Basin Resources Inc. ("Great Basin") which allowed us to acquire a 100% interest in a salt wells projects (the "Salt Wells Projects") in the State of Nevada if we incurred certain project related expenditures. The Earn-in Agreement with Great Basin provided for a 3% revenue royalty if concentrates or ores of minerals were sold in the future. During February 2025, we chose not to renew certain mining claims related to the Salt Wells Projects, which effectively terminated the Earn-in Agreement with Great Basin, and we have no further interests in the project.

## Available Information
We make available free of charge on our website, *www.5eadvancedmaterials.com*, our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to the Exchange Act, as soon as reasonably practicable after we electronically file such information with, or furnish it to, the SEC. These documents are also available on the SEC's website at *www.sec.gov*. The information on our website is not, and shall not be deemed to be, a part of this Annual Report on Form 10-K or incorporated into any of our other filings with the SEC.

------

## Item 1A. Risk Factors
Each of the risks described below should be carefully considered, together with all of the other information contained in this Annual Report on Form 10-K, before making an investment decision with respect to our securities. In the event of the occurrence, reoccurrence, continuation or increased severity of any of the risks described below, our business, financial condition or results of operations could be materially and adversely affected, and you may lose all or part of your investment. The risks included here are not exhaustive. Other sections of this Annual Report may include additional factors which could adversely affect our business and financial performance. New risks emerge from time to time and it is not possible for management to predict all such risks, nor can it assess the impact of all such risks on our business or the extent to which any risk, or combination of risks, may cause actual results to differ materially.

## Risks Relating to Our Business
***There is substantial doubt regarding our ability to continue as a going concern. We will need to raise substantial additional funding, which may not be available on acceptable terms, if at all, to be able to continue as a going concern and advance our Project.***

There is substantial doubt regarding our ability to continue as a going concern. Our existence in our current form is dependent upon our ability to obtain additional capital. Our cash and cash equivalents as of the date of this report will not be sufficient for us to continue as a going concern or to fund our long-term operations. Raising funds in the current economic environment is challenging and financing may not be available in sufficient amounts or on acceptable terms, if at all. The issuance of additional securities, whether equity or debt, or the possibility of such issuance, or the securing of financing that investors consider to be unfavorable to us, may cause the market price of our shares to decline. The sale of additional equity or debt securities may dilute the ownership of existing shareholders.

***We will need to obtain additional financing to continue as a going concern and to continue our ongoing development and proposed operations.***

We have limited assets upon which to develop and commence our business operations and to rely otherwise. We will need to seek significant additional funds in the future through equity or debt financings, government funding or grants, private capital, royalty agreements or customer prepayments, or other strategic alliances with third parties, either alone or in combination to fund our business plan and to complete our mining exploration initiative. Our business plan, which includes the development of the Project, has required and will continue to require substantial capital expenditures. We will require financing to fund our engineering phases, development, construction, and initial commercial production activities and are required to raise additional capital in respect of continuing our proposed mining exploration program, pre-production activities, legal, operational set-up, general and administrative, marketing, employee salaries and other related expenses. For example, as previously disclosed, in September 2024, we received a non-binding letter of intent from the Export-Import Bank of the United States ("EXIM") for a loan-backed guarantee on project debt financing of up to $285 million for our proposed commercial-scale facility. We have had continued engagement with representatives from EXIM on the loan package, but we cannot make any assurances that the loan package will be finalized on a timely basis, on the currently proposed terms, or at all.

If we are unable to raise adequate funds, we may have to delay, reduce the scope of or eliminate some or all of our business plan expenditures, and the failure to procure such required financing could have a material and adverse effect on our business, liquidity, financial condition and results of operations as well as our ability to continue as a going concern. If we are unable to continue as a going concern, we might have to liquidate our assets and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our financial statements. The inclusion of the going concern explanatory paragraph by our auditors, our lack of cash resources and our potential inability to continue as a going concern may materially adversely affect our business, share price, and our ability to raise new capital or to enter into critical contractual relations with third parties due to concerns about our ability to meet our contractual obligations.

Obtaining additional funding will be subject to various additional factors, including investor acceptance of our business plan, the status of our development program and ongoing results from our exploration and development efforts. If we are not able to secure adequate additional funding when needed, we will need to re-evaluate our operating plan and may be forced to make significant reductions in spending, extend payment terms with suppliers, liquidate assets where possible, limit, suspend or curtail planned development programs and cease operations entirely. Having insufficient funds may also require us to relinquish rights to assets and technology that we would otherwise prefer to develop ourselves, or on less favorable terms than we would otherwise choose. The foregoing actions and circumstances could materially adversely impact our business, liquidity, results of operations and future prospects.

------

Any such required financing may not be available in amounts or on terms acceptable to us or at all, and the failure to procure such required financing could have a material and adverse effect on our business, financial condition and results of operations, or threaten our ability to continue as a going concern. In addition, if we are unsuccessful in raising the required funds, we may need to modify our operational plans to continue as a going concern, and we may have to delay, reduce the scope of or eliminate some or all of our planned development activities or proposed exploration and development programs at the Project. In the event additional capital resources are unavailable, we may also be forced to sell some or all of our properties in an untimely fashion or on less than favorable terms. Any of these factors could harm our operating results.

Until successful commercial production is achieved from the Project, allowing for the generation of sufficient revenue to fund our continuing operations, we will continue to incur operating and investing net cash outflows associated with, among other things, developing the Project, maintaining our properties and undertaking ongoing exploration and optimization activities. As a result, we rely on access to capital markets as a source of funding for our capital and operating requirements. We require additional capital to fund our ongoing operations, including the operation of our Small-scale Facility (the "SSF"), progress engineering for our proposed commercial-scale facility, testing and analysis to further de-risk our wellfield design and bring the Project into production, which will require funds for construction and working capital. We cannot assure you that such additional funding will be available to us on satisfactory terms, or at all, or that we will be successful in commencing and maintaining commercial borates or byproduct extraction, production of advanced boron materials, or that our sales projections for these and other products will be realized.

Depending on the type and the terms of any financing we pursue, shareholders' rights and the value of their investment in our common stock, par value $0.01, ("Common Stock") and CHESS Depositary Interests ("CDIs") could be reduced. Any additional equity financing will dilute stockholdings, and new or additional debt financing, if available, may involve restrictions on financing and operating activities. In addition, if we issue secured debt securities, the holders of the debt would have a claim to our assets that would be prior to the rights of shareholders until the debt is paid. Interest on such debt securities would increase costs and negatively impact operating results. If the issuance of new securities results in diminished rights to holders of our Common Stock and CDIs, the market price of our Common Stock and CDIs could be negatively impacted. Any sale of securities will also need to comply with the applicable rules of the stock exchanges on which our securities are listed or quoted for trading. Further, strategic collaboration or royalty agreements may provide us with non-dilutive or minimally dilutive financing but adversely impact our future results of operations or capital resources. There is no guarantee that we will be able to secure any additional funding or be able to secure funding which will provide us with sufficient funds to meet our objectives, which may adversely affect our business and financial position.

## *We have incurred significant net operating losses since our inception and anticipate that we will incur continued losses for the foreseeable future.* 
We had an accumulated deficit of $231.6 million as of June 30, 2025, and we expect to incur significant discovery and development expenses in the foreseeable future related to the completion of development and commercialization of the Project. As a result, we expect we will continue to sustain substantial operating and net losses, and it is possible that we will never be able to sustain or develop the revenue levels necessary to attain profitability. If we are unable to raise sufficient capital when needed, our business, financial condition and results of operations could be materially and adversely affected, and we may need to modify our operational plans. In addition, if we were unable to raise sufficient capital in the future, it may be determined that we would be unable to continue as a going concern, which could have a further material adverse impact on our business and financial condition.

***Our future performance is difficult to evaluate because we have no or only a limited operating history in the minerals industry and no revenue from our proposed extraction operations at our properties, which may negatively impact our ability to achieve our business objectives.***

Although the Project deposit was identified over 60 years ago and significant work has been undertaken to refine the resource estimate and development plan since that time, including by our immediate predecessor, ABR, which undertook significant development activities to develop the resource estimate and mine plan for the Project, we have not realized any material revenues to date from the sale of mineral products. To date, our operating cash flow needs have been financed primarily through equity and equity-linked financing and not through cash flows derived from our operations.

We currently produce an insignificant amount of material from our SSF and we have not sold any material amounts of product derived from our properties. As a result, our revenues are expected to be determined, to a large degree, by the development and future success of our proposed commercial-scale facility at the Project, subsequent operating activities as well as ongoing commercial and marketing efforts to establish offtake agreements for material products. Our revenues will also be substantially impacted by the prevailing prices for borates and its derivatives, calcium chloride, gypsum and other byproducts, to the extent that these products can be successfully extracted. At the present time, the recovery process for lithium has not been field tested and determined, and the cost and efficiency of such process will likely not be addressed until a later point in our development cycle. For the products that we aim to

------

successfully produce in the future, market prices are dictated by supply and demand, and we cannot predict or control the price we will receive for boric acid and its derivatives, calcium chloride, gypsum, lithium carbonate and other byproducts. Although management has identified currently favorable market conditions concerning the supply and demand of boric acid and advanced boron materials, future market conditions may be significantly less favorable as a result of numerous factors, including many that are beyond the scope of our control.

We were incorporated in September 2021, and we have only recently begun to implement our current business strategy. As a result, we have little or no historical financial and operating information available to help you evaluate our future financial and operating performance. Therefore, it is possible that actual costs may increase significantly, and we may not be able to achieve our expected results. The Project may ultimately be less profitable than currently anticipated or may not be profitable at all, which could have a material adverse effect on our results of operations and financial position.

***If we do not obtain additional financing and maintain sufficient funds to continue our ongoing development and proposed operations, our proposed business may be at risk or the execution of our business plan may be delayed.***

We have limited assets upon which to develop and commence our business operations and to rely otherwise. As of June 30, 2025 and June 30, 2024, we had cash and cash equivalents of $3.8 million and $4.9 million, respectively. We have had recurring net losses from operations and an accumulated deficit of $231.6 million as of June 30, 2025 and $200.0 million as of June 30, 2024. Given our net losses and with only these funds, we will need to seek significant additional funds in the future through equity or debt financings, or strategic alliances with third parties, either alone or in combination with debt or equity financings to fund our business plan and to complete our mining exploration initiative. Our business plan, which includes the development of the Project, has required and will continue to require substantial capital expenditures. We will require financing to fund our planned pre-production activities and are required to raise additional capital in respect of continuing our proposed mining exploration program, pre-production activities, legal, operational set-up, general and administrative, marketing, employee salaries and other related expenses.

The scope of our current business plan for the next 12 months includes, among other things: operation of the SSF to provide the necessary data for our commercial-scale facility, progress our customer qualification program and validate our wellfield design and operational plans; progress FEL-3 and the related detailed engineering and vendor testing; optimize well-field design and operating plan in an effort to reduce future mining capital and operational expenditures through various drilling techniques such as directional, horizontal, and radial drilling; pursue and optimize infrastructure capital expenditures for our larger-scale facility which could include expansion of non-potable water resources, upgrading shore power, connection to a natural gas network, preparing certain lands for the construction of the proposed commercial-scale facility, and constructing new access roads into and out of the location for our proposed commercial-scale facility; and further define our advanced boron materials strategy with consideration to engineering and repurposing our SSF once sufficient data has been obtained for flow sheet optimization and the production of product for customer qualification. It will be necessary for us to obtain additional financing during the next 12 months for us to fund and achieve the full scope of our current business plan. Further, we have incurred net losses and negative operating cash flows in each quarter since our inception and expect to incur significant losses in future periods as we continue to increase our expenses to pursue the development of our business.

Additional development work will be required beyond the scope of our current 12-month business plan in order to optimize, design and engineer operational processes at our proposed commercial-scale facility at the Project, which we expect will assist in our technical and economic analysis of the Project. Such additional development work may include additional drilling and detailed engineering work, continued operation of the SSF to provide the necessary data for our commercial-scale facility, tests of our wellfield design and operational plans, and progression of our customer qualification program, among others. We expect to source the capital needed for such additional development work from additional capital raises or other financing activities.

Our ability to raise additional funds may also be adversely impacted by an economic slowdown, higher inflation, increased interest rates, supply chain issues, diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, uncertainty about economic stability and uncertainty about economic policy, including tariffs. If the equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly and more dilutive.

Certain market disruptions may increase our cost of borrowing or affect our ability to access one or more financial markets. Such market disruptions could result from:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•adverse economic conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•adverse general capital market conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•poor performance or cyclical decline of the borates, or mining industries in general;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•bankruptcy or financial distress of unrelated companies or marketers engaged in the borates industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•significant decrease in demand for borates; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•adverse regulatory actions that affect our development and construction plans or the use of borates generally.

Our previous development plans were focused on boron and SOP extraction and developing a commercial-scale complex without first developing a smaller scale pilot facility, such as the SSF. During 2023, we updated our business plan with three phases of scaled production which represented a change in project scope compared to previous business plans. Our business plan now includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a focus on boron (as opposed to boron and SOP under our previous plans) and calcium-based co-products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Phase 1 targets production of 130,000 short tons per annum of boric acid with calcium byproducts of calcium chloride and gypsum, with targeted initial commercial production in the second half of calendar year 2028.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Expansion phases of additional tonnage of borates and calcium based co-products, advanced boron materials, and economically accretive byproducts.

In addition, the capital expenditures related to our proposed commercial-scale facility continue to be subject to change as our technical and economic analysis progresses. Such changes could also be material, including without limitation as a result of potential future price increases for major equipment or labor, and future operating data from our SSF which may result in changes in the design and engineering of our proposed commercial-scale facility. The foregoing factors may lead to materially higher costs, delays or the inability to complete our proposed commercial-scale facility as planned or on commercially reasonable terms or at all. Furthermore, future operating data from the SSF during FEL-3 engineering may provide reason for a change or changes to the engineering for our proposed commercial-scale facility, resulting in a difference in the expected total capital expenditures and ongoing required operating expenditures related thereto. As a result, depending on the timing, nature, quality and specificity of the data we receive from the ongoing operation of the SSF, we may require significant additional capital before we can progress the development of our proposed commercial-scale facility. Such additional capital may be needed to fund further detailed engineering work, including engineering work to define, with a reasonable degree of certainty, the capital expenditures required for our proposed commercial-scale facility and in particular related to equipment and drilling. We may also need additional capital for continued operation of the SSF to prepare boric acid for our customer qualification program, continued testing and analysis of our wellfield to finalize its commercial-scale design, and to evaluate data and design to complete detailed engineering work for the proposed commercial-scale facility. As a result, we can provide no assurance that we will be able to meet our expected timelines, capital expenditure and costs estimates with respect to either the ongoing operation of our SSF or proposed commercial-scale facility and we may need significant additional capital to pursue our operating plans, which capital may not be available to us on commercially reasonable terms or at all. Our inability to obtain any such required additional capital on commercially reasonable terms would have a material adverse impact on our business, operations, liquidity and financial position.

***Our inability to continue to operate the SSF, and our inability to complete further technical and economic studies with respect to the Project, may have a material adverse impact on the Project.***

The SSF is our smaller scale boron facility which serves as a foundation for future design, engineering, and cost optimization for our proposed commercial-scale facility at the Project. We believe that the continued successful operation of the SSF is an important path to obtaining critical information that will help enable us to optimize the efficiency, output and economic profile of our proposed commercial-scale facility. While the SSF has been operational for more than a year, it continues to provide valuable data and information to enhance the detailed engineering of the proposed commercial-scale facility, operational processes and operating expenditures.

The ongoing operation of the SSF, learnings, and data collection are being undertaken in parallel with the engineering process of the proposed commercial-scale facility. This approach has a higher risk of re-work of certain portions of the Project, as information and data we receive may cause us to revise or redesign portions of the proposed commercial-scale complex, causing potential delays and increased design costs. Further, additional technical and economic studies may be required to assist in determining the economic recoverability of mineral resources for the Project. An abbreviated process development approach may also lead to technical risk, and higher capital and operating expenditures. We cannot assure you that the proposed commercial-scale facility at the Project will be completed on schedule, within budget or at all, or achieve an adequate return on investment. We are also a newly formed company which makes it more difficult for you to evaluate our track record of meeting various milestones or target completion deadlines.

Further, the ongoing operation of the SSF is maintenance intensive, requires us to incur operating costs including labor and raw materials, among others, and may require additional capital expenditures to replace existing equipment, to test proposed designs or processes or evaluate modifications to our processes. We cannot assure you that we will have access to sufficient capital to continue the operation of the SSF, or that such costs and expenditure will result in a positive economic outcome for the Project.

------

Our inability to continue to operate the SSF may delay or prevent the completion of further technical and economic studies. Our ability to complete further technical and economic studies could materially and adversely impact the ability to secure additional funding and thereby delay or otherwise have a material adverse impact on the Project. If additional technical and economic studies are undertaken, the outcomes may not be favorable, and we may be unable to maintain commercial viability. Any further technical studies may also indicate that substantial additional financing will be required to complete the Project. We cannot give any assurance that we will be successful in completing any such financing or that such financing will be available to us if and when required or on satisfactory terms, or at all.

***We have invested and, subject to availability of adequate capital, plan to continue to invest significant amounts of capital in the Project on exploration and development activities, which involve many uncertainties and future operating risks that could prevent us from realizing profits on expected timeframes or at all.***

In total, we have spent in excess of $156 million on the Project thus far, including resource drilling, monitoring wells, metallurgical test works, well injection tests, permitting activities, construction and operation of the SSF, pilot-scale test works and engineering of the commercial-scale facility. For the year ended June 30, 2025, our capital expenditures per our statement of cash flows were $2.1 million.

Our business is capital intensive. Specifically, the extraction and recovery of borates and other potential byproducts, the mining costs, the maintenance of machinery and equipment, and the compliance with applicable laws and regulations, each require substantial operating and capital expenditures. Subject to the availability of adequate capital, we plan to continue to invest significant capital over the next several years on the development of the Project to bring it into production and will have to continue to invest capital to maintain or increase the amount of mineral reserves we hold and our rates of production once commercialization of the Project has occurred. Mining exploration is highly speculative in nature, involves many risks and is frequently unsuccessful. Development and production activities may involve many uncertainties and operating risks that could prevent us from realizing profits, putting pressure on our consolidated balance sheet and credit rating. Unforeseen issues, including increasing the required amount of capital expenditure necessary to bring the Project into production, the impact of volatility in the borates market and its derivatives, calcium chloride, gypsum and other prices, our ability to enter into supply contracts with buyers, and obstacles or complexities that could arise in the environmental or permitting process may cause us not to proceed with any one or a combination of these activities. Moreover, once mineralization is discovered, it may take a number of years from the initial phases of drilling before production is possible, during which time the economic feasibility of production may change. We previously targeted reaching initial commercial production in fiscal year 2026. Given the permitting hurdles and time to obtain final EPA approval and resource constraints in fiscal year 2024, we are now targeting to reach initial commercial production in the second half of calendar year 2028. This target continues to be dependent on a number of factors and assumptions, including obtaining the requisite funding for, and the successful construction of, our proposed commercial-scale facility, in addition to obtaining and maintaining applicable permits, and there can be no assurance that we will be able to meet any such target on time, on budget, or at all due to many factors including our limited experience in successful construction of similar projects, the complexity of the project, supply chain issues, higher costs, construction delays, cost overruns, planned and unplanned shutdowns, turnarounds, outages and other delays and interruptions. If and when production begins, no assurance can be given that we will be able to maintain our production levels or generate sufficient cash flow, capitalize a sufficient amount of our net profit or have access to sufficient equity investments, bank loan or other debt financing alternatives to fund our capital expenditure at a level necessary to continue our exploration and exploitation activities. In addition, we cannot assure you that existing or future projects, if approved and executed, will be completed on schedule, within budget or achieve an adequate return on investment.

The amounts and timing of expenditures will depend on the progress of ongoing development, the results of consultants' analyses and recommendations, the rate at which operating losses are incurred, and other factors, many of which are beyond our control. Whether the mineral deposits we have discovered will be successfully extracted depends on a number of factors, which include, without limitation, the particular attributes of the deposit, prices for the minerals and the volatility of their respective markets, and governmental regulations. If we cannot complete development activities and commence and maintain mining operations, we may never generate revenues and will never become profitable.

The Project may be delayed, more costly than anticipated or unsuccessful for many reasons, including declines in borate prices and its derivatives, calcium chloride, gypsum, and lithium carbonate, cost overruns, project implementation schedule slippage, shortages of or delays in the delivery of equipment or purpose-built components from suppliers, escalation in capital costs estimates, mechanical or technical difficulties, increases in operating costs structures, possible shortages of construction or other personnel, other labor shortages or industrial action, pandemic or localized epidemic, environmental occurrences during construction that result in a failure to comply with environmental regulations or conditions on development, or delays and higher-than expected costs, unanticipated natural disasters, accidents, miscalculations, unanticipated financial events, political or other opposition, litigation, acts of terrorism, operational difficulties or other events associated with such construction that may result in the delay, suspension or

termination of the Project, resulting in further costs, the total or partial loss of our investment and a material adverse effect on our results of operations, financial performance and prospects.

***We have a limited history of mineral production and we may not be able to successfully achieve our business strategies, including our downstream processing ambitions.***

We are a development stage company and we have a limited history of mining or refining mineral products from our properties. As such, any future revenues and profits are uncertain. There can be no assurance that the Project will successfully reach commercial-scale production of minerals or otherwise generate operating earnings. Advancing projects from the development stage into commercial production requires significant capital and time and will be subject to further technical and economic studies, permitting requirements and construction of mines, processing plants, roads and related works and infrastructure. We will continue to incur losses until mining-related operations successfully reach commercial production levels and generate sufficient revenue to fund continuing operations. There is no certainty that we will generate revenue from any source, operate profitably or provide a return on investment in the future.

In addition, substantial additional capital will be required to develop and support potential downstream processing capabilities at the Project. The economic viability of the production of advanced boron materials at the Project will be dependent on a number of factors beyond the scope of our control, including the market demand for and competitive landscape of the advanced boron materials that we hope to produce. We cannot assure you that our downstream processing ambitions will operate profitably or provide a return on investment in the future.

***We may be unable to develop or acquire certain intellectual property required to implement our business strategy successfully.***

A key element of our long-term business strategy is to develop high-performance, borates and advanced boron materials that support downstream applications in the areas of clean energy infrastructure, electric transportation, and high-grade fertilizers among other end uses. To implement this strategy successfully, we may need to license certain intellectual property related to these downstream processes and/or develop the ability, or collaborate with, purchase or form a joint venture with commercial partners. In addition, other licenses that may be necessary for some of these downstream processing steps have not yet been obtained. Any failure to establish or maintain collaborative, joint venture or licensing arrangements for the production of borates, calcium chloride, gypsum, lithium or other specialty products on favorable terms could adversely affect our business and prospects. No assurances can be given that we will be able to successfully license any such intellectual property, or that we will be able to do so on favorable terms. If we materially breach the obligations in any future licensing agreements, the licensor typically has the right to terminate the license and we may not be able to market products that are covered by the license, which could adversely affect our competitive business position and harm our business prospects. In addition, any claims brought against us by any future licensors could be costly and time-consuming and would divert the attention of our management and key personnel from our business operations.

Other licenses that may be necessary for some of our proposed downstream processing steps have not yet been obtained. Any failure to establish or maintain collaborative, joint venture or licensing arrangements for the production of boron or other specialty products on favorable terms could adversely affect our business and prospects.

***Third parties may claim that we infringe on their proprietary intellectual property rights, and resulting litigation may be costly, result in diversion of management's time and efforts, require us to pay damages or prevent us from marketing our future products.***

Our commercial success will depend in part on not infringing, misappropriating or violating the intellectual property rights of others. From time to time, we may be subject to legal proceedings and claims, including claims of alleged infringement of trademarks, copyrights, patents and other intellectual property rights held by third parties. In the future, third parties may sue us for alleged infringement of their proprietary or intellectual property rights. We may not be aware of whether our products do or will infringe existing or future patents or the intellectual property rights of others. Any litigation in this regard, regardless of outcome or merit, could result in substantial costs and diversion of management and technical resources as well as harm to our brand, any of which could adversely affect our business, financial condition and results of operations. If the party claiming infringement were to prevail, we could be forced to discontinue the use of the related technology or design and/or pay significant damages unless we enter into royalty or licensing arrangements with the prevailing party or are able to redesign our products or processes to avoid infringement. Any such license may not be available on reasonable terms, if at all, and there can be no assurance that we would be able to redesign our products or processes in a way that would not infringe the intellectual property rights of others. In addition, any payments we are required to make and any injunction we are required to comply with as a result of such infringement could harm our reputation and financial results.

------

***All of our business activities are now in the development stage, but there can be no assurance that our development efforts will result in commercial development.***

All of our operations are at the development stage and there is no guarantee that any such activity will result in commercial production. Although a certain amount of drilling has been conducted at the Project to date, the evaluation of the final mine plan is not yet complete, relies upon the ongoing operation of the SSF, horizontal wells, and we can provide no assurance that the evaluation of horizontal drilling will result in favorable outcomes that support that our proposed mine plans are feasible to develop the Project. Significant additional drilling and mine design activities could be required to develop the Project.

The exploration and development of boron and other byproducts involves significant risks which even a combination of careful evaluation, experience and knowledge cannot eliminate. While the discovery of these minerals may result in substantial rewards, few properties which are explored are ultimately developed into producing mines. Major expenses may be required to establish and develop proven and probable mineral reserves, to develop processes and to construct mining and processing facilities at a particular site, including at the Project. It is impossible to ensure that the exploration and development programs planned by us or any future development programs will result in a profitable commercial mining operation. There is no assurance that our mineral exploration and development activities will result in any discoveries of commercial quantities of boron, lithium, or any other materials or byproducts. There is also no assurance that any mineral property will be brought into commercial production. Whether a mineral deposit will be commercially viable depends on a number of factors, some of which are: the particular attributes of the deposit, such as size, grade and proximity to infrastructure, the run of mine solution produced, engineering of the plant and process to produce a commercial product, prices of minerals and the volatility of their respective markets; raw material input prices and the related volatility thereof, and government regulations, including regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of minerals and environmental protection. These factors and others are beyond our control, and the effects of these factors cannot be accurately predicted. Our long-term profitability will be in part related to the cost and success of our proposed exploration and development programs and any subsequent development programs at the Project and elsewhere.

***We are a development stage company and our estimates of mineral resources and reserves remain inherently uncertain and subject to significant change, and the actual volume and grade of material actually recovered may differ materially from current estimates.***

During August 2025, we advanced our Project from the exploration stage by filing a Preliminary Feasibility Study, resulting in the conversion of certain measured and indicated resources into proven and probable reserves. Despite this advancement, there remains considerable uncertainty in our resource and reserve estimates due to the inherent risks and subjective judgments involved in such assessments. Investors should not assume that the mineral reserve and resource estimates described under "Properties–Mineral Resource Estimate" and "Properties–Mineral Reserve Estimate" will be fully or economically extracted. Although certain mining and processing activities have been completed at the Project to date, additional drilling activities may be necessary to validate our wellfield design and operational plan for the commercial-scale facility, which serve as the basis for our estimates of mineral resources and reserves in our Preliminary Feasibility Study, and additional drilling will be necessary to construct the wellfield that will supply the commercial-scale facility. Each of these activities may result in changes to our estimates of mineral resources and reserves.

The Project deposit has had a significant amount of prior drilling and is the subject of at least four separate historic mineral resource estimates, including a 2018 initial feasibility study prepared for ABR prepared according to the Joint Ore Reserves Committee (the "JORC Code"), a second feasibility study originally released in April 2020 and updated further in February 2021 also prepared for ABR in accordance with the JORC Code, an amended initial assessment report released by us in May 2023 and further revised in February 2024, and a Preliminary Feasibility Study released by us in August 2025. None of the prior ABR mineral resource estimates were Regulation S-K 1300 compliant, and each report resulted in a different amount of mineral resource estimates. The Preliminary Feasibility Study released in August 2025, contains a combined 5.3 million short tons of proven and probable reserves of H3BO3, using a 2.0% cut-off grade for B2O3. Additional time and expenditures are required to commercially mine and to construct, complete and install mining and processing facilities in those properties that are actually mined and developed. Any expenditure that we may make in the development of any refined borates and advanced boron materials may not result in the discovery of any commercially exploitable mineral deposits or such advanced boron materials.

The mineral reserve estimates stated in this filing and extracted from the Preliminary Feasibility Study represent the amount of boric acid that the QP in that report estimated could be economically and legally extracted or produced at the time of the mineral reserve determination. There can be no assurance that our disclosed mineral reserve estimates can be recovered and any material reductions in the quantity of mineral reserves or the related grades or increase in cost of production could have a material adverse effect on our business, financial condition or prospects. Estimates of resources and reserves are subject to considerable uncertainty, and the estimation of mineral resources and reserves are a subjective process. Such estimates are expressions of judgment based on knowledge, experience and industry practice at the time of the estimation and will be, to a large extent, based on the interpretations, which may be imprecise or which may later prove to be inaccurate, of geologic data obtained from drill holes and other exploration techniques and which may not necessarily be indicative of future results. Estimates made at a given time may change significantly in

------

the future when new information becomes available. We expect that the estimates of resources and reserves will change to reflect such updated information. Resource and reserve estimates may be revised upward or downward based on the results of current and future drilling, testing or production levels, significantly lower borate prices as a result of a decrease in commodity prices, increases in operating costs, reductions in metallurgical recovery or other modifying factors, and this could result in material write-downs of our investment in mining properties and increased amortization, reclamation and closure charges. Such revisions may also render previously disclosed estimates of mineral resources and reserves uneconomical. We cannot assure you that any particular level of recovery of borates or other minerals from discovered mineralization will in fact be commercially realized. Actual operating and capital cost and economic returns on projects may differ significantly from original estimates. Further, it may take many years to commence production, during which time, the economic feasibility of production may change. The exploration and development of mineral deposits involve a high degree of financial risk over a significant period of time which a combination of careful evaluation, experience and knowledge of management may not eliminate.

We are engaged in the business of exploring and developing mineral properties with the intention of locating economic deposits of minerals. Our property interests are at the pre-commercial-production stage. Accordingly, it is unlikely that we will realize profits in the short term, and we cannot assure you that we will realize profits in the medium to long term. Any profitability from our business in the future will be dependent upon development of an economic deposit of minerals and further exploration and development of other economic deposits of minerals, each of which is subject to numerous risks that are outside of our control.

In addition, pre-production projects like the Project have no operating history upon which to base estimates of future operating costs and capital requirements. Project projections, such as any future estimates of reserves, mineral recoveries or cash operating costs will to a large extent be based upon the interpretation of geologic data, obtained from a limited number of mining data and other sampling techniques, and interpretation of market studies and estimates, which are subject to change. Actual operating costs and economic returns may materially differ from the costs and returns estimated, and accordingly, our financial condition, future results of operations, and cash flows may be negatively affected.

***Estimates relating to the development of the Project and mine plan are uncertain and we may incur higher costs and lower economic returns than estimated.***

Mine development projects such as the Project typically require a number of years and significant expenditures during the development phase before production is possible. These projects could experience unexpected problems and delays during development, construction and mine start-up. Our decisions concerning the development of the Project deposit have been based on the results of multiple studies performed under the JORC Code and S-K 1300, which have estimated the anticipated economic returns of the Project. The actual profitability or economic feasibility of the Project may differ from our estimates as a result of any of the following risks normally encountered in the mining industry, such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•changes in tonnage, grades and metallurgical characteristics of ore to be mined and processed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•changes in input commodity and labor costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the quality of the data on which engineering assumptions are made;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•adverse geotechnical conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•availability of adequate and skilled labor force, adequate machinery and equipment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•availability, supply and cost of water and power;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•fluctuations in inflation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•availability and terms of financing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•delays in obtaining environmental or other government permits or approvals or changes in the laws and regulations related to project development or operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•changes in tax laws, the laws and/or regulations around royalties and other taxes due to the local, state and federal governments and any royalty agreements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•weather or severe climate impacts, including, without limitation, prolonged or unexpected precipitation, drought, wildfires and/or sub-zero and extreme temperatures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•accidental fires, floods, earthquakes or other natural disasters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•controlling water and other similar mining hazards;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•liability for pollution, other environmental damage, or harm to plants or animals, including endangered or protected species;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•potential delays and restrictions in connection with health and safety issues, including pandemics and infectious diseases;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•potential delays relating to social and community issues, including, without limitation, issues resulting in labor disputes, protests, road blockages or work stoppages;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•uncertainties regarding our ability to successfully implement downstream processing and reach full revenue potential;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•potential challenges to mining activities or to permits or other approvals or delays in development and construction based on claims of disturbance of cultural resources or the inability to secure consent for such disturbance; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•other known and unknown risks involved in the conduct of exploration, development and the operation of mines.

Any of the aforementioned risks may cause substantial delays to the Project and require significant capital outlays, adversely affecting our future earnings and competitive position and, potentially, our financial viability. In addition, the nature of some of these risks is such that liabilities could exceed any applicable insurance policy limits or could be excluded from coverage. As many of the risks described above are also risks against which we cannot insure or against which we may elect not to obtain insurance, we are not fully insured against all potential risks incident to our business. The potential costs which could be associated with any liabilities not covered by insurance, or in excess of insurance coverage, or compliance with applicable laws and regulations could be substantial. As a result of market conditions, certain insurance may become unavailable or available only for reduced amounts of coverage. If we were to incur a significant loss for which we were not fully insured, it could have a material adverse effect on our business, results of operations, financial condition and liquidity.

***We depend on a single mining project.***

The Project accounts for all of our mineral resources and reserves and the current potential for the future generation of revenue. Any adverse development affecting the Project will have a material adverse effect on our business, prospects, profitability, financial performance and results of operations. These developments include, but are not limited to, the inability to obtain necessary permits or financing to develop the Project, changes in technical parameters of project development, changes in costs or anticipated costs which may make it uneconomic to develop and/or operate the Project, unusual and unexpected geologic formations, seismic activity, rock bursts, flooding, drought, and other conditions involved in the drilling and removal of material, any of which could result in damage to, or destruction of, property, and which could hinder the development and future operation of the Project. If the Project is completed to management's contemplated target production capacity of up to 450,000 tons per year of boric acid, it will exceed the limits of our existing permits, which would require us to seek modifications to the permits. There can be no assurance that we could obtain any required permit modifications. Based on the Preliminary Feasibility Report, and assuming we reach economically viable production, the Project, by its nature, will have a defined production life (the period during which extraction will remain viable). Ultimately, we will be required to replace and expand our resources and any established reserves if we are to maintain operating revenues. In the absence of additional mineral projects, we will be solely dependent on the Project for our revenue and profits, if any. Our ability to maintain or increase our annual production will be dependent, in significant part, on our ability to expand the Project, bring new projects into production and to complete acquisitions.

***Our long-term success will depend ultimately on our ability to achieve and maintain profitability and to develop positive cash flow from our proposed operating activities.***

Our long-term success, including the recoverability of the carrying values of our assets, our ability to acquire and develop additional projects, and continuing with the exploration, development and commissioning and operating activities of the Project will depend ultimately on our ability to achieve and maintain profitability and to develop positive cash flow from our operations by establishing ore bodies that contain commercially recoverable borates, lithium, and other minerals and to develop these into profitable operating activities. The economic viability of our future operating activities has many risks and uncertainties including, but not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a significant, prolonged decrease in the market price of borates, lithium, gypsum, calcium chloride and other minerals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•difficulty in marketing and/or selling borates, lithium, gypsum, calcium chloride and other minerals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•significantly higher than expected capital costs to construct the Project;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•significantly higher than expected extraction costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•significantly lower than expected borates, lithium, and other minerals extraction;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•significant delays, reductions or stoppages of borates, lithium, and other minerals extraction activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the introduction of significantly more stringent regulation affecting our activities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•global political, economic and market conditions, including political disturbances, war, terrorist attacks and changes in global trade policies and tariffs.

Our future operating activities may change as a result of any one or more of these risks and uncertainties, and we cannot assure you that any ore body that we extract mineralized materials from will result in achieving and maintaining profitability and developing positive cash flow.

***Our growth depends upon the continued growth in demand for end use and future facing applications that require borates, lithium, and related minerals and compounds we expect to produce.***

Our growth is dependent upon the continued adoption and demand by consumers of end use applications, such as solar and wind energy infrastructure, neodymium-ferro-boron magnets, lithium-ion batteries, and future facing applications, including the semi-conductor, aerospace, military, and automotive markets, which currently require borates, lithium, and related minerals and compounds we expect to produce. If the market for such applications does not develop as we expect, develops more slowly than we expect, and/or current boron producers fulfill all or a portion of the market's anticipated boron needs, our business, prospects, financial condition and results of operations will be affected. The market for such end use applications is relatively new, rapidly evolving, and could be affected by numerous external factors such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•government regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•tax and economic incentives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•rates of consumer adoption; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•competition.

***Our long-term success will depend on our ability to enter into and deliver product under supply agreements.***

Because we have not yet begun production of mineral products, we currently do not have any binding supply agreements with any customers. We may encounter difficulty entering into or maintaining supply agreements for our products, may fail to deliver required minimum amounts required by such agreements or may experience production costs in excess of the fixed price to be paid to us under such agreements.

In September 2021, we announced entry into a non-binding letter of intent with Borman Specialty Materials. Under the terms of the letter of intent, we agreed to work together towards a binding agreement for the supply of boric acid and other borates and advanced boron materials, which will be used to manufacture products with critical applications for future global markets, including the semi-conductor, life sciences, aerospace, military and automotive markets.

In May 2022, we also announced entry into a non-binding letter of intent with Rose Mill. Under the terms of the letter of intent, we agreed to work together on supplying advanced boron materials that focus on industrial and military applications.

In June 2022, we signed a non-binding letter of intent with Corning Incorporated for the supply of boron and lithium materials, technical collaboration to develop advanced boron materials and potential financial accommodation in support of a commercial agreement.

In December 2022, we signed a non-binding letter of intent with Estes Energetics to collaborate in producing boron-based materials for solid rocket motors used in U.S. space and military applications.

In May 2023, we signed a non-binding letter of intent with Orbital Composites to provide boron feedstock for 3D printing of wind turbines, permanent magnets, and boron carbide for defense applications.

We cannot assure you that the conditions for the closing of any of these non-binding agreements, which have not yet been completed, will be satisfied or, as applicable, waived or that the non-binding agreements will be finalized at all. Likewise, non-binding agreements that have not yet been completed may be completed on terms that differ, perhaps substantially, from those described herein. If the closing conditions are not satisfied or waived on a timely basis, or if another event occurs delaying, preventing or terminating these non-binding agreements, or if we are otherwise unable to enter into binding product and supply agreements, such delay, failure or termination of the non-binding agreements, or inability to enter into binding product and supply agreements, could

------

cause uncertainty or other negative consequences that may materially and adversely affect our business, financial performance and operating results.

Our business, results of operations and financial condition may be materially and adversely affected if we are unable to enter into similar agreements with other parties, we are unable to mutually agree to matters required by the non-binding agreements with Borman Specialty Materials, Rose Mill, Corning, Estes Energetics, and Orbital Composites and are unable to deliver the product required by such agreements, we are otherwise unable to enter into binding product and supply agreements, or we experience costs in excess of the price set forth in such agreements.

***If the estimates and assumptions we use to determine the size of our total addressable market are inaccurate, including its current size, growth trajectory, and the underlying factors that may drive future growth in overall market size, particularly for boron where there is limited third party published research and market forecasting, our future growth rate may be adversely affected, and the potential growth of our business may be limited.***

Our estimate of the annual total addressable market for our proposed products is based on a number of internal and third-party estimates, which are based on a number of factors, including, without limitation, historical and current global demand and pricing, the number and geographic location of global and regional suppliers and their current capacity capabilities, and the growing number of end-use applications and demand for such applications. Market estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may prove to be inaccurate. Even if the market in which we compete meets our size estimates and forecasted growth, our business could fail to grow at similar rates, if at all. Our market opportunity is also based on the assumption that our existing and future offerings will be more attractive to our customers and potential customers than competing products and services. If these assumptions prove inaccurate, our business, financial condition and results of operations could be adversely affected.

***The cost and availability of electricity and natural gas are subject to volatile market conditions.***

Mining development projects and operations consume large amounts of raw materials and energy. We may rely on third parties for the supply of energy we consume and will consume in our development and mining activities. The prices for and availability of electricity, natural gas, oil and other energy resources are all also subject to worldwide supply and demand, volatile market conditions, often affected by weather conditions, as well as political and economic factors beyond our control. Variations in the cost of raw materials, and of energy, which primarily reflects market prices for oil and natural gas, may significantly affect our operating results from period to period. Even if we choose to supply the Project with electricity from a cogeneration facility that we own and/or operate, we will be dependent on a supply of natural gas from a third party for the operation of the facility. We must have dependable delivery of energy in order to develop and ultimately operate our facilities. Accordingly, we are at risk in the event of an energy disruption. Prolonged black-outs or brown-outs or disruptions caused by natural disasters, or other means, would substantially disrupt our production. Moreover, we expect much of our finished borate products to be delivered by truck. Unforeseen fluctuations in the price of fuel attributable to fluctuations in crude oil prices would also have a negative impact on our costs or on the costs of many of our future customers. In addition, changes in certain environmental regulations in the U.S., including those that may impose output limitations or higher costs associated with climate change or greenhouse gas emissions legislation or regulation, could substantially increase the cost of inputs to our operations, such as energy, to us and other borate producers.

***Inadequate infrastructure may constrain our future mining operations, including at the Project.***

Any potential commercial production at the Project will depend on adequate infrastructure. In particular, reliable power sources, water supply, transportation and surface facilities are all necessary to develop and operate mines. Failure to adequately meet these infrastructure requirements or changes in the cost of such inputs could affect our ability to develop or commence production at the Project and could have a material adverse effect on our business, financial condition, results of operations, cash flows or prospects.

***Uncertain global economic conditions could have a material adverse effect on our business, financial condition, results of operations or prospects, including the pricing of our products.***

Our financial results are tied to global economic conditions and their impact on levels of consumer confidence and consumer spending. Global consumer markets can be impacted by significant U.S. and international economic downturns and inflation, such as the economic contraction caused by the coronavirus pandemic of 2020 and the global credit crunch experienced in 2008. High levels of inflation, recession or a weak recovery, due to factors that include, but are not limited to, disruptions in financial markets, federal budget, tax, tariff or trade policy issues in the United States, political upheavals, war or unrest, economic sanctions against trading nations, and demonetization, could cause us to experience significant cost increases and revenue declines due to deteriorated consumer

------

confidence and spending, and a decrease in the availability of credit or on commercially acceptable terms, which could have a material adverse effect on our business prospects or financial condition.

Our business is also dependent upon certain industries, such as energy, automotive, agriculture, transportation, petrochemical and original equipment manufacturing, and these are also cyclical in nature. Therefore, these industries may experience their own significant fluctuations in demand for our products based on such things as economic conditions, energy prices, consumer demand and infrastructure funding decisions by governments. Many of these factors are beyond our control. As a result of the volatility in the industries we plan to serve, we may ultimately have difficulty increasing or maintaining our level of sales or profitability. If the industries we serve were to suffer a downturn, then our business may be adversely affected.

Prices and availability of commodities consumed or used in connection with exploration and development and mining, such as natural gas, diesel, oil and electricity, also fluctuate, and these fluctuations have and could in the future affect the costs of operations. These fluctuations can be unpredictable, can occur over short periods of time and may have a material adverse impact on our operating costs or the timing and costs of various projects.

***Our business could be affected by macroeconomic risks****.*

Our operations and performance depend significantly on global and regional economic conditions. Macroeconomic conditions, including inflation, slower growth or recession, changes to fiscal and monetary policy, tighter credit, higher interest rates, high unemployment and currency fluctuations can materially adversely affect demand for our products and services. In addition, confidence and spending can be materially and adversely affected in response to financial market volatility, negative financial news, declines in income or asset values, energy shortages and cost increases, labor and healthcare costs and other economic factors. An adverse impact on demand for our products, uncertainty about, or a decline in, global or regional economic conditions can have a significant impact on our suppliers and other partners. Potential effects include financial instability; inability to obtain credit to finance operations and purchases of our products; and insolvency. We cannot predict the timing or scale of these various macroeconomic conditions, but they could have a material adverse effect on our business, results of operations and financial condition.

***Government efforts to combat inflation, along with other interest rate pressures arising from a recently inflationary economic environment, could lead to higher financing and Project completion costs.***

Over the past several years, global and U.S. levels of monetary inflation have been higher than recent historical averages. Government entities have taken various actions to combat inflation, such as raising interest rate benchmarks. Government entities may continue their efforts, or implement additional efforts, to combat inflation, which could include among other things continuing to raise interest rate benchmarks or maintaining interest rate benchmarks at elevated levels. Such government efforts, along with other interest rate pressures arising from an inflationary economic environment, could lead to higher financing costs and have a material adverse effect on our business, financial condition and results of operations.

***We are subject to anti-bribery, anti-corruption, and anti-money laundering laws, including the U.S. Foreign Corrupt Practices Act, as well as export control laws, customs laws, sanctions laws and other laws governing our operations. If we fail to comply with these laws, we could be subject to civil or criminal penalties, other remedial measures and legal expenses, which could adversely affect our business, results of operations and financial condition.***

The U.S. Departments of Justice, Commerce, State and Treasury and other federal agencies and authorities have a broad range of civil and criminal penalties they may seek to impose against corporations and individuals for violations of economic sanctions laws, export control laws, the U.S. Foreign Corrupt Practices Act (the "FCPA"), and other federal statutes and regulations, including those established by the Office of Foreign Assets Control ("OFAC"). Under these laws and regulations, as well as other anti-corruption laws, anti-money laundering laws, export control laws, customs laws, sanctions laws and other laws governing our operations, various government agencies may require export licenses, may seek to impose modifications to business practices, including cessation of business activities in sanctioned countries or with sanctioned persons or entities and modifications to compliance programs, which may increase compliance costs, and may subject us to fines, penalties and other sanctions. A violation of these laws or regulations would negatively affect our business, financial condition and results of operations.

We are continuing to implement policies and procedures designed to ensure compliance by us and our directors, officers, employees, representatives, consultants and agents with the FCPA, OFAC restrictions and other export control, anti-corruption, anti-money-laundering and anti-terrorism laws and regulations. We cannot assure you, however, that our policies and procedures are or will be sufficient or that directors, officers, employees, representatives, consultants and agents have not engaged and will not engage in conduct for which we may be held responsible, nor can we assure you that our business partners have not engaged and will not engage in conduct that could materially affect their ability to perform their contractual obligations to us or even result in our being

------

held liable for such conduct. Violations of the FCPA, OFAC restrictions or other export control, anti-corruption, anti-money laundering and anti-terrorism laws or regulations may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could have a material adverse effect on our business, financial condition and results of operations.

***Title to mineral properties and related water rights is a complex process and we may suffer a material adverse effect in the event the Project property or other properties that we may acquire are determined to have title deficiencies.***

Acquisition of title to mineral properties and related water rights is a very detailed and time-consuming process. Title to, and the area of, mineral properties may be disputed. We cannot give any assurance that title to such property will not be challenged or impugned. Mineral properties sometimes contain claims or transfer histories that examiners cannot verify. A successful claim that we do not have title to the Project property or lack appropriate water rights could cause us to lose any rights to explore, develop and mine any minerals on that property, without compensation for our prior expenditures relating to such property.

***Challenges to our mining claims could adversely affect our operations and financial condition.***

Certain of our mining activities depend upon the validity and enforceability of mining claims, including unpatented mining claims, which are subject to potential challenges from third parties, regulatory bodies, or governmental agencies. Such challenges may include assertions that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•A mining claim is invalid due to improper staking, inaccurate or incomplete documentation, or non-compliance with applicable laws and regulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•A mining claim lacks proper tenure, ownership, or rights due to disputed title or conflicting ownership claims.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The type of mining claim (e.g., lode versus placer) has been incorrectly characterized, which may impact our rights to extract minerals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The boundaries or location of a mining claim have been incorrectly established or recorded.

If any of our mining claims are challenged successfully, we may lose rights to some or all of the mineral deposits within those claims. The resolution of any such challenges, whether through litigation or administrative procedures, can be costly, time-consuming, and uncertain. An adverse determination could require us to modify or terminate our mining activities on the affected properties, incur substantial costs to rectify deficiencies, or significantly delay our mining plans. Such outcomes could materially and adversely affect our operations, financial condition, and results of operations.

***Restrictions on our ability to obtain, recycle and dispose of water may impact our ability to execute our development plans in a timely or cost-effective manner.***

Water is an essential component of our planned mining processes. We currently have two water production wells in an aquifer within our permit boundary, but water is limited in the Mojave Desert. If our demand for water were to outpace supply, our ability to perform mining operations could be restricted or made more costly. Along with the risks of other extreme weather events, drought risk, in particular, is likely increased by climate change. If we are unable to obtain sufficient water to use in our operations, we may be unable to economically produce our target minerals, which could have an adverse effect on our financial condition, results of operations and cash flows.

***The development, construction and proposed operation of our properties and projects is subject to various environmental and operational regulations, and risks relating to land use restrictions and potential opposition from landowners, environmental groups and other third parties, all of which could adversely affect or prevent our ability to grow.***

Our properties and Project are subject to numerous environmental laws, regulations, guidelines, policies and other requirements relating to, among other things, local land use, zoning, building and operational laws and regulations. We may also operate in jurisdictions with little or no land use regulations or programs. Requirements that are in place for mining projects may require conformance with specified generation capacities, sound levels, radar setbacks, as well as restrictions on communications interference, hazards to aviation or navigation, or other potential nuisances.

Mining projects may experience local opposition in certain markets due to claims based on these alleged nuisances, concerns about conversion of land use from agriculture or undeveloped land to mining, or other claims of potential adverse health or environmental impacts, such as misuse of water resources, landscape degradation, land use, food scarcity or price increase. We could experience significant opposition from third parties, including environmental non-governmental organizations, local landowners,

------

neighborhood groups, municipalities and other entities either during the permit application process, including during any public hearings, comment periods or appeal proceedings, or after environmental permits are issued. We could also experience renewed opposition if any permit requires amendment.

Any such opposition may be taken into account by government officials responsible for granting the relevant permits, which could result in the permits being delayed, not being granted or being granted solely on the condition that we carry out certain corrective measures to our proposed projects (including at the Project), which could materially increase our operational costs. In addition, we may become subject to legal proceedings or claims contesting the construction or operation of our projects or permits required thereunder. Any such delays, permit restrictions, legal proceedings or disputes (even if ultimately decided in our favor) could materially delay our ability to complete construction of a project (including at the Project) in a timely manner, or at all, materially increase the costs associated with commencing or continuing such project's commercial operations or harm our reputation. Any settlement of claims or unfavorable outcomes or developments relating to these proceedings or disputes, such as judgments for monetary damages, injunctions or denial or revocation of permits, could have a material adverse effect on our business, financial condition, results of operations, and reputation.

***The mining industry is historically a cyclical industry and market fluctuations in the prices of borates and other minerals could adversely affect our business.***

We may derive revenues from the extraction and sale of borates, calcium-based co-products and other minerals. The marketability of minerals is affected by numerous factors beyond our control. These factors include government regulations relating to pricing, taxes, royalties, allowable production, imports, exports, prevailing price, price volatility, supply, changes in buyer preferences and demand for borates and other minerals. The prices of such commodities have historically fluctuated, and may in the future fluctuate widely and may be affected by numerous factors beyond our control, including international, economic and political trends, domestic and foreign tax policy, the price of imports of commodities, the cost of exploration, development, production and processing mineral ore, available transportation capacity, expectations of inflation, currency exchange fluctuations, interest rates, global or regional consumptive patterns, speculative activities, increased production due to new or improved extraction and production developments and methods, technological changes in the markets for the end products and the overall supply and demand for minerals. The effect of these factors on the price of borates and other minerals, and therefore the economic viability of any of our exploration properties, cannot accurately be predicted. Additionally, new production of borates from current or new competitors in the borates market could adversely affect prices. Any additional supply (including as a result of new investments) could have an adverse effect on the price of such materials. Only limited information is available with respect to the status of expansion and new borate production capacity expansion projects being developed by current and potential competitors, and, as such, we cannot make accurate projections regarding the future capacities of current and possible new entrants into the market and the dates on which such capacities could become available on the market. If these potential projects are completed in the short term, they could adversely affect market lithium prices, thereby resulting in a material adverse effect on the economic feasibility of extracting any minerals we discover.

Changes in commodity prices would affect our revenues and may reduce the amount of funds available to reinvest in development activities. Reductions in mineral prices not only reduce our revenues and profits but could also reduce the quantities of any reserves that are commercially recoverable. Declining mineral prices may also adversely impact our operations by requiring a review of the commercial feasibility of any of our proposed exploration and development programs. Any such review may indicate a material adverse effect on the economic feasibility of our proposed business.

***Fluctuations in the value of the United States dollar relative to other currencies may adversely affect our business.***

Fluctuations in the value of the dollar can be expected to affect our business. A strong U.S. dollar would likely result in imported borate products becoming comparatively less expensive, potentially leading to increased competition from foreign producers importing into the U.S. Additionally, a strong dollar could negatively impact our export competitiveness, making our products more expensive for foreign buyers, thereby potentially reducing international sales volumes and revenues. Conversely, a weak U.S. dollar may make imported products comparatively more expensive, reducing competition from foreign imports, and may enhance our export competitiveness by making our products relatively less expensive in foreign markets, potentially increasing our international sales opportunities. These currency fluctuations, whether strengthening or weakening the U.S. dollar, introduce volatility and uncertainty in our pricing, sales, profitability, and overall competitive position in both domestic and international markets.

***We face risks relating to mining, exploration, and mine construction, if warranted, on our properties.***

Our level of profitability, if any, in future years will depend to a great degree on borate prices and whether our properties can be brought into production. Exploration and development of borate resources are highly speculative in nature, and it is impossible to ensure that the currently proposed and future exploration programs and/or feasibility studies on our existing properties will fully

------

monetize the reserves. Whether it will be economically feasible to extract boron depends on a number of factors, including, but not limited to: the particular attributes of the deposit, such as size, grade and proximity to infrastructure; boron prices and volatility of the market; mining, processing and transportation costs; the willingness of lenders and investors to provide project financing on commercially reasonable or favorable terms; labor costs and possible labor strikes; and governmental regulations, including, without limitation, regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting materials, foreign exchange, environmental protection, employment, worker safety, transportation, and reclamation and closure obligations. The effect of these factors cannot be accurately predicted, but any one or a combination of these factors may result in us receiving an inadequate return on invested capital. In addition, we are subject to the risks normally encountered in the mining industry, such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the discovery of unusual or unexpected geological formations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•accidental fires, floods, earthquakes, severe weather or other natural disasters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•unplanned power outages and water shortages;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•construction delays and higher than expected capital costs due to, among other things, supply chain disruptions, higher transportation costs and inflation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•controlling water and other similar mining hazards;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•explosions and mechanical failure of equipment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•operating labor disruptions and labor disputes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the ability to obtain suitable or adequate machinery, equipment or labor;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•our liability for pollution or other hazards; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•other unknown risks involved in the conduct of exploration and operation of mines.

The nature of these risks is such that liabilities could exceed any applicable insurance policy limits or could be excluded from coverage. There are also risks against which we cannot insure or against which we may elect not to insure. The potential costs, which could be associated with any liabilities not covered by insurance or in excess of insurance coverage, or compliance with applicable laws and regulations may cause substantial delays and require significant capital outlays, adversely affecting our future earnings and competitive position and potentially our financial viability.

***Mineral exploration and development, such as our proposed operations, are subject to extraordinary risks.***

Mineral exploration, development and production involves many risks which even a combination of experience, knowledge and careful evaluation may not be able to overcome. The industrial activities conducted at our facilities present significant risk of serious injury or death to our employees, customers or other visitors to our operations, notwithstanding our safety precautions, including our material compliance with federal, state and local employee health and safety regulations. While we have in place policies and procedures to minimize such risks, we may nevertheless be unable to avoid material liabilities for an injury or death. Our operations will be subject to geological, technical and operating hazards and risks inherent in the exploration for mineral resources and, if we discover a mineral resource in commercially exploitable quantity, our operations could be subject to all of the hazards and risks inherent in the development and production of resources, including liability for pollution or similar hazards against which we cannot insure or against which we may elect not to insure. Any such event could result in work stoppages and damage to property, including damage to the environment. Even though we maintain workers' compensation insurance and a general liability policy to address the risk of incurring material liabilities for injury or death, there can be no assurance that the insurance coverage will be adequate or will continue to be available on the terms acceptable to us, or at all, which could result in material liabilities for an injury or death. The payment of any liabilities that arise may have a material adverse impact on us.

***Our proposed facilities or operations could be adversely affected by natural or human causes outside of our control, such as natural disasters, wars or health epidemics or pandemics.***

We may be impacted by natural disasters, wars, health epidemics or pandemics, terrorist attacks, civil unrest, cyber threats or attacks, or other events outside of our control. For example, the Project is located in San Bernardino County, California near active faults, which may make our operations more susceptible to nearby earthquakes. If major disasters such as earthquakes, wildfires, health epidemics or pandemics, floods, drought, or other events occur, or our information system or communications network breaks down or operates improperly, our ability to achieve or continue operations at the Project may be seriously damaged, or we may have to stop or delay our proposed exploration and development, and eventually production and shipment of our products. We may incur

------

expenses or delays relating to such events outside of our control, which could have a material adverse impact on our business, operating results and financial condition.

***A shortage of skilled technicians and engineers may further increase our operating costs, which may materially adversely affect our results of operations.***

Efficient production of borates products using modern techniques and equipment requires skilled technicians and engineers. In addition, our efforts will significantly increase the number of skilled operators, maintenance technicians, engineers and other personnel required to successfully operate our business. In the event that we are unable to hire, train and retain the necessary number of skilled technicians, engineers and other personnel there could be an adverse impact on our labor costs and our ability to reach anticipated production levels in a timely manner, which could have a material adverse effect on our results of operations.

***Changes in U.S. trade policies, including the imposition of tariffs, could materially increase the cost of constructing our proposed commercial-scale facility and materially adversely impact the economic viability of our project.***

Our planned commercial-scale facility for in-situ mining of boron will require significant capital investment, currently estimated to be approximately $435 million, inclusive of contingency. The construction of this facility will involve sourcing equipment from within the United States, but also from various European countries and other international sources. Recent and potential future changes in U.S. trade policies, including tariffs implemented or proposed by the U.S. government and any retaliatory actions taken in response by foreign governments, could significantly increase the cost of imported equipment and materials required for the construction of our facility.

The economic feasibility study included in our Preliminary Feasibility Study, and the related cost analyses, have not accounted for the impact of existing or future tariffs. The ultimate impact of currently announced tariffs and any future tariffs or trade policies will depend on various factors, including the timing of implementation and the amount, scope and nature of such tariffs or policies. Given the uncertainty and volatility surrounding trade and tariff policies, particularly in light of historical shifts in tariff approaches, including those imposed under the current Trump administration, we may experience materially increased costs that are difficult to predict accurately at this time. Such cost increases could negatively affect the projected economics of our facility and our ability to access financing, potentially causing the economic feasibility of the project to deteriorate substantially or render the project economically unviable, thereby causing us to delay, significantly modify, or cancel the project entirely, which would have a material adverse effect on our business, financial condition, results of operations, and prospects.

***A shortage of equipment or disruption in our supply chain could adversely affect our ability to operate our business.***

We are dependent on various supplies and equipment to carry out our mineral exploration and development activities. Any shortage of such supplies, equipment and parts could have a material adverse effect on our ability to carry out our operations and therefore limit or increase the cost of potential future production.

Further, we are subject to risk from fluctuating market prices of certain raw materials, including steel, fiberglass reinforced plastic, and bulk chemicals, which are necessary to the construction, maintenance and operation of our assets. The price of these raw materials may be affected by supply restrictions or other market factors (including inflation) from time to time. Some of the components and materials related to our current and planned assets will be sourced from outside the United States through arrangements with various vendors, and we may experience delays in obtaining these components and materials as a result of shipping and transportation constraints, and other supply chain disruptions. Political, social or economic instability in regions where these components and materials are made could cause future disruptions in trade.

Actions in various countries have created uncertainty with respect to tariff impacts on the costs of some of these components and materials. The degree of our exposure is dependent on (among other things) the type of some of these components and materials. Significant price increases for these raw materials could reduce our operating margins, and could harm our business, financial condition, and results of operations.

In particular, bulk chemicals are critical to the operation of our business. These raw materials are in high demand, subject to price fluctuations and of limited availability. If manufacturers are not able to procure enough of these components or procure them in a timely manner, this would have a material adverse effect on the development of our products and in turn, our business, financial conditions and results of operations. Significant price increases for bulk chemicals in particular may have an adverse impact on the economic viability of our proposed development and operating activities.

------

***Disruptions in production at our proposed facilities may have a material adverse impact on our business, results of operations and/or financial condition.***

Manufacturing facilities in our industry are subject to planned and unplanned production shutdowns, turnarounds, outages and other disruptions. Any serious disruption at our proposed commercial-scale facility could impair our ability to use our facilities and have a material adverse impact on any future revenues and increase our costs and expenses. Long-term production disruptions may allow competitors to be sought for alternative supply which could further adversely affect our profitability or delay or keep us from reaching commercial development at all.

Unplanned production disruptions may occur for external reasons including natural disasters, weather, disease, strikes, transportation interruption, government regulation, political unrest or terrorism, or internal reasons, such as fire, unplanned maintenance or other manufacturing problems. We may experience delays in construction, equipment procurement, or in completing our proposed commercial-scale facility on time. Any such production disruption could have a material impact on our proposed operations, operating results and financial condition.

***Failure by our vendors or our component or raw material suppliers to use legal or ethical business practices and comply with applicable laws and regulations may adversely affect our proposed business.***

We do not control our vendors or suppliers or their business partners. Accordingly, we cannot guarantee that they follow legal or ethical business practices, such as fair wage practices and compliance with environmental safety and other local laws. A lack of demonstrated compliance could lead us to seek alternative manufacturers or suppliers, which could increase our costs and result in delayed delivery of components and raw materials, or other disruptions of our operations. Violation of labor or other laws by our manufacturers or suppliers or the divergence of a supplier's labor or other practices from those generally accepted as ethical in the U.S. or other markets in which we do and expect to do business could also attract negative publicity for us and harm our proposed business.

***Competition with and new production of borates and other minerals from current or new competitors in the market could adversely affect prices and our proposed business.***

The mining industry is highly competitive. According to Global Market Insights, as of 2025, there are two major competitors in the borates industry, Rio Tinto Borates and Eti Maden. If we are successful in bringing the Project into production, we would be competing with two large competitors in the borates industry, one global mining conglomerate and one state-owned enterprise, both of which we believe are generally well-funded and established. Competition principally involves sales, supply and labor prices, contractual terms and conditions, attracting and retaining qualified personnel and securing the services and supplies we need for our operations. We cannot guarantee that competition with these two major competitors for boron, as well as with others, will not adversely affect us in the future. For example, lower cost producers of the minerals we mine could be better positioned to manage future volatility through commodity price cycles. Any significant production increases from either of the aforementioned two main borate competitors, and others, or the discovery of any additional significant borate resources could negatively impact prices received for borates. Furthermore, it is possible that competitors may engage in pricing activities that could result in market price reductions that may materially and adversely impact the economic feasibility of our plans. In addition, mines have limited lives and, as a result, we must periodically seek to replace and expand our mineral resources by acquiring new properties. Significant competition exists to acquire mining concessions, land and related assets.

We expect that our competitors may have well-established relationships with our current and potential suppliers, lenders and customers and have extensive knowledge of our target markets. As a result, these competitors may be able to respond more quickly to evolving industry standards and changing customer requirements than we may be able to. The adoption of more advanced technology could reduce our competitors' production costs or may result in other efficiencies and, if we do not adopt such technologies, our competitors may have a lower cost structure or greater production efficiency, which may adversely affect our ability to compete.

There is limited information on the status of new production capacity expansion projects being developed by the current and potential competitors and, as such, we cannot make accurate projections regarding the capacities of possible new entrants into the market and the dates on which any new projects could become operational but any significant increase in supply could adversely affect market prices for borates, thereby resulting in a material adverse effect on the economic feasibility of extracting our resources.

***Industry consolidation may result in increased competition, which could have a material adverse effect on our proposed business.***

Some of our competitors have made or may make acquisitions or enter into partnerships or other strategic relationships to achieve competitive advantages. In addition, new entrants not currently considered competitors may enter our market through

------

acquisitions, partnerships or strategic relationships. We expect industry consolidation to continue and/or increase as demand for critical materials increases. Industry consolidation may result in competitors with more compelling product offerings or greater pricing flexibility than we may have, or business practices that make it more difficult for us to compete effectively, including on the basis of price, sales, technology or supply. These competitive pressures could have a material adverse effect on our proposed business.

***We are subject to significant environmental and government regulations and compliance with such regulations requires significant expenditures.***

Mining activities in the United States are subject to extensive federal, state, local and foreign laws and regulations governing environmental protection, natural resources, prospecting, development, production, post-closure reclamation, taxes, labor standards and occupational health and safety laws and regulations, including mine safety, toxic substances and other matters. The costs associated with compliance with such laws and regulations are substantial. In addition, changes in such laws and regulations, or more restrictive interpretations of current laws and regulations by governmental authorities, could result in unanticipated capital expenditures, expenses or restrictions on or suspensions of our operations and delays in the development of our properties.

As a current holder of interests in U.S. mineral properties, we may be subject to CERCLA. CERCLA, along with analogous statutes in certain states, imposes strict, joint and several liability on owners and operators of facilities which release hazardous substances into the environment. CERCLA imposes similar liability upon generators and transporters of hazardous substances disposed of at an off-site facility from which a release has occurred or is threatened. Under CERCLA's strict joint and several liability provisions, we could potentially be liable for all remedial costs associated with property that we currently or previously owned or operated regardless of whether our activities are the actual cause of the release of hazardous substances. Such liability could include the cost of removal or remediation of the release and damages for injury to the natural resources. Releases from such facilities or from any of our current U.S. properties due to past or current activities could form the basis for liability under CERCLA and its analogs. In addition, off-site disposal of hazardous substances, including hazardous mining wastes, may subject us to CERCLA liability. Our current and prior U.S. properties are not, to our knowledge, currently listed or proposed for listing on the National Priority List and we are not aware of pending or threatened CERCLA litigation which names us as a defendant or concerns any of our current or prior U.S. properties or operations. However, we have not conducted a Phase 1 or similar environmental site assessment on our properties and cannot be certain that we are aware of all current or historical operations at or affecting our properties that could involve contamination. We cannot predict the potential for future CERCLA liability with respect to our U.S. properties, nor can we predict the potential impact or future direction of CERCLA litigation in the area surrounding our current and prior properties.

Environmental regulations, including climate change related legislation or regulations, mandate, among other things, the maintenance of air and water quality standards, land development and land reclamation, and set forth limitations on the generation, transportation, storage and disposal of solid and hazardous waste. Enhanced public and private focus on climate change, greenhouse effects and proposed or contemplated laws and regulations relating to carbon emissions may impact aspects of our development plans or our future production. Environmental legislation is evolving in a manner that may require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects, and a heightened degree of responsibility for mining companies and their officers, directors and employees. In connection with our current activities or in connection with our prior operating activities, we may incur environmental costs that could have a material adverse effect on financial condition and results of operations. Any failure to remedy an environmental problem could require us to suspend operations or enter into interim compliance measures pending completion of the required remedy.

We may also incur substantial costs, including fines, damages, criminal or civil sanctions and remediation costs, or experience interruptions in our operations, for violations arising under these laws and regulations or permit requirements. If we violate environmental, health and safety laws or regulations, in addition to being required to correct such violations, we can be held liable in administrative, civil or criminal proceedings for substantial fines and other sanctions could be imposed that could disrupt or limit our operations. Liabilities associated with the investigation and clean-up of hazardous substances, as well as personal injury, property damages or natural resource damages arising from the release of, or exposure to, such hazardous substances, may be imposed without regard to violations of laws or regulations or other fault, and may also be imposed jointly and severally.

We may in the future be subject to claims by third parties or employees relating to exposure to hazardous materials and the associated liabilities may be material.

Any failure to ensure on-going compliance with current and future laws and government regulations, including environment, workplace health and safety, tax and accounting laws, rules and regulations as well as stock exchange listing rules could have a material adverse effect on our future financial condition and prospects.

------

***We may face increased costs and be subject to liability resulting from the generation and disposal of certain wastes, including hazardous wastes, in the course of the Project's development and/or other future operations.***

Our business is subject to stringent and complex laws and regulations relating to the generation, use, handling, storage, recycling, disposal and exposure to solid and hazardous wastes. These laws are frequently subject to change. In the course of our operations, we may generate solid or certain hazardous wastes through the disposal of other materials utilized in our development activities or our future operations. In addition, environmental laws can result in the imposition of liability in connection with end-of-life system disposal.

We own and lease real property and may be subject to requirements regarding the storage, use and disposal of hazardous substances, including spill prevention, control and counter-measure requirements. If our owned or leased properties are contaminated, whether during or prior to our ownership or operation, we could be responsible for the costs of investigation and cleanup and for any related liabilities, including claims for damage to property, persons or natural resources. That responsibility may arise even if we were not at fault and did not cause or were not aware of the contamination. The costs of compliance with laws relating to the management and disposal of solid and hazardous wastes or the remediation of any contamination to which we are or may be responsible, and any changes to our operations mandated by new or amended laws, may be significant. Failure to comply with such laws and regulations could result in significant expenses, delays or fines, which in turn could have a material adverse effect on our results of operations and financial position.

***Land reclamation requirements may be burdensome on our financial position.***

Land reclamation requirements are generally imposed on companies with mining operations or mineral exploration companies in order to minimize long term effects of land disturbance. We are required to mitigate long-term environmental impacts at the Project by stabilizing, contouring, re-sloping, and revegetating various portions of the site after well-field and processing operations are completed. In addition, we are responsible for plugging and abandoning all injection recovery, water monitoring, and exploration drilling holes. In undertaking these reclamation activities, we must meet comprehensive environmental protection and reclamation standards. Any failure to meet such standards may subject us to fines, penalties, or other sanctions. In addition, in order to carry out reclamation obligations imposed on us in connection with exploration, potential development and production activities, we must allocate financial resources that might otherwise be spent on exploration and development programs. We currently have reclamation obligations and have arranged and pledged certificates of deposits for reclamation. If we are required to carry out unanticipated reclamation work, our financial position could be adversely affected.

***The physical consequences of climate change could have a material adverse effect on our properties and proposed business activities.***

Climate change may increase the frequency or intensity of adverse weather conditions, such as tropical storms, wildfires, droughts, floods, hurricanes, tornadoes, extreme temperatures or ice storms and may have the long-term effect of changing weather patterns in ways that are difficult to anticipate, which may result in damage or destruction to our assets or to third party assets on which we rely, affect the availability of water for our facilities, or otherwise require us to incur costs, or elicit changes in applicable regulations in the jurisdictions in which we operate, which may result in, among other impacts, increased compliance costs, reduced revenues, restrictions on our proposed operations, and difficulties in obtaining or maintaining permits, licenses or authorizations required for our proposed business. Any such disruption may prevent us from continuing to develop the Project and any other of our properties, or, if and when completed, operating in the normal course.

Certain of our operations are dependent on particular meteorological conditions. Climate change may have a long-term and permanent effect on meteorological patterns, including the frequency or intensity of wind, precipitation, or change in temperatures at the Project and any other of our properties. Furthermore, components of our systems could be damaged by severe weather, such as wildfires, hailstorms, tornadoes, hurricanes, flooding, drought, high or low temperatures or other weather conditions. Replacement and spare parts for key components may be difficult or costly to acquire or may be unavailable. Unfavorable weather and atmospheric conditions could impair the effectiveness of our assets or reduce their output beneath their estimated or engineered capacity or require shutdown of key equipment, impeding future operation of our assets.

Increasing concentration of greenhouse gases in the Earth's atmosphere are contributing to climate changes that are having significant physical effects, such as increased frequency and severity of storms, droughts, fires, floods and other climatic events. If any such effects were to occur in the regions in which we explore, develop and operate, they could adversely affect or delay such activities and may otherwise cause us to incur significant costs in preparing for or responding to those effects.

***New or evolving sustainability and climate-related disclosure obligations, as well as increased expectations regarding management of sustainability matters from various stakeholders, could result in additional costs for compliance, restrictions on our access to capital, and increased litigation and reputational risk.***

In March 2024, the SEC adopted final rules providing a framework for reporting climate-related risks and creating new disclosure obligations for registrants, including requirements related to climate-related governance, risk management processes, greenhouse gas ("GHG") emissions, and certain climate-related financial statement metrics. However, implementation of the rules was voluntarily stayed in April 2024 due to multiple legal challenges, and in March 2025 the SEC announced it would cease defending the rules in court. Litigation remains ongoing in the Eighth Circuit Court of Appeals, with certain state governments intervening in support of the rules. As of the date of this report, the SEC's climate disclosure rules are not in effect, and their future status remains uncertain.

In October 2023, California enacted the Climate Corporate Data Accountability Act ("CCDAA"), or SB 253, and the Climate-Related Financial Risk Act ("CRFRA"), or SB 261. The CCDAA requires both public and private U.S. companies that are "doing business in California" and that have total annual revenue of $1 billion to publicly disclose and verify, on an annual basis, Scope 1, 2 and 3 GHG emissions. The CRFRA requires the disclosure of a biennial climate-related financial risk report, aligned with TCFD or ISSB standards, for public and private companies that are "doing business in California" and have total annual revenue of $500 million. Reporting under both laws is scheduled to begin in 2026, although the California Air and Resource Board ("CARB") is still undergoing its rulemaking process, and both laws are being challenged in federal court.

In September 2024, Australia introduced sustainability and climate-related reporting requirements into the Corporations Act. As a registered foreign company, the Company is not required to prepare a sustainability report under these requirements.

We are still assessing the potential impacts of these laws and other evolving sustainability and climate-related disclosure regimes that we may be subject to. Implementation could result in additional compliance costs, increased costs of and restrictions on access to capital, and reputational or other harm if our disclosures are perceived as insufficient or fail to meet verification or third-party standards. We may also face increased litigation risks relating to alleged damages from GHG emissions, statements made by us or others in our industry about climate-related risks, or any disclosures we make in connection with emissions reporting, particularly given the complexity of overlapping or diverging regulatory requirements and evolving stakeholder expectations.

Further, investors, employees, customers and other stakeholders are increasingly judging companies' performance on a variety of sustainability matters. Numerous organizations publish sustainability ratings or assessments, which influence investment decisions and are often publicized. Topics evaluated include climate impacts, human rights, land use, human capital management, ethics and compliance, and board oversight of sustainability issues. There can be no assurance that we will successfully manage such issues or meet evolving stakeholder expectations. Failure to do so could result in adverse impacts on our reputation, relationships, business, or operating results.

***We are required to obtain, maintain, and renew governmental permits in order to conduct development and mining operations, a process which is often costly and time-consuming.***

We are required to obtain, maintain and renew governmental permits for our development activities and, prior to mining any mineralization, we will be required to modify or obtain new governmental permits for our proposed operations. Certain of our land titles could be subject to lease and royalty payments that are either currently payable or may be payable in the future (subject to negotiation with the State of California). Obtaining, maintaining, and renewing governmental permits is a complex and time-consuming process. The timeliness and success of permitting efforts are contingent upon many variables, not all of which are within our control, including the interpretation of permit approval requirements administered by the applicable permitting authority. We may not be able to obtain, maintain, or renew permits that are necessary to our planned operations or the cost and time required to obtain, maintain, or renew such permits may exceed our expectations. Any unexpected delays or costs associated with the permitting process could delay the development or operation of our properties, which in turn could materially adversely affect our future revenues and profitability. In addition, key permits and approvals may be revoked or suspended or may be changed in a manner that adversely affects our activities.

Private parties, such as environmental activists, frequently attempt to intervene in the permitting process and to persuade regulators to deny necessary permits or seek to overturn permits that have been issued. Obtaining the necessary governmental permits involves numerous jurisdictions, public hearings and possibly costly undertakings. These third-party actions can materially increase the costs and cause delays in the permitting process and could potentially cause us to not proceed with the development or operation of our properties. In addition, our ability to successfully obtain key permits and approvals to explore for, develop, operate and expand operations will likely depend on our ability to undertake such activities in a manner consistent with the creation of social and economic benefits in the surrounding communities, which may or may not be required by law. Our ability to obtain permits and

------

approvals and to successfully operate in particular communities may be adversely affected by real or perceived detrimental events associated with our activities.

***Lawsuits may be filed against us or arbitration proceedings may be commenced and an adverse ruling in any such lawsuit or arbitration may adversely affect our business, or financial condition.***

In the ordinary course of our business, we may become involved in, named as a party to, or be the subject of, various legal proceedings, including regulatory proceedings, tax proceedings and legal actions, including arbitration proceedings, relating to personal injuries, workers' compensation, employment discrimination, property damage, property taxes, land rights, the environment, damages related to breaches of privacy or data security, and contract disputes. Such proceedings and actions may involve liquidated damages, consequential damages, punitive damages and civil penalties or other losses, or injunctive or declaratory relief. In addition, we may also be subject to class action lawsuits, including those alleging violations of the Fair Labor Standards Act and state and municipal wage and hour laws.

Due to the inherent uncertainties of litigation and other dispute resolution proceedings, the outcome of outstanding, pending or future actions or proceedings may be difficult to assess or quantify, cannot be predicted with certainty and may be determined adversely to us and as a result, could have a material adverse effect on our assets, liabilities, business, financial condition or results of operations. Even if we prevail in any such action or proceeding, they could be costly and time-consuming and may divert the attention of management and key personnel from our business operations, which could adversely affect our financial condition. The ultimate resolution of any litigation or proceeding through settlement, mediation, or a judgment could have a material impact on our reputation and adversely affect our financial performance and financial position.

Moreover, governmental authorities and private parties may bring lawsuits based upon damage to property and injury to persons resulting from the environmental, health and safety impacts of prior and current operations, including operations conducted by other mining companies many years ago at sites located on properties that we currently own or own in the future. These lawsuits could lead to the imposition of substantial fines, remediation costs, penalties and other civil and criminal sanctions. We cannot assure you that any such law, regulation, enforcement or private claim would not have a material adverse effect on our financial condition, results of operations or cash flows.

***We are vulnerable to the risks associated with operating in a single geographic region and concentrating our capital investment in the State of California increases our exposure to that risk.***

We expect to focus our operational activities and capital investments at the Project in California. Should we be able to bring the Project into production, we would then be solely dependent upon a single mining operation for our revenue and profits and all of our operations would be conducted in a single geographic region in the western United States in California. The geographic concentration of our operations may disproportionately expose us to disruptions in our operations if the region experiences severe weather, transportation capacity constraints, constraints on the availability of required equipment, facilities, personnel or services, significant governmental regulation or natural disasters. If any of these factors were to impact the region in which we operate more than other borate producing regions, our business, financial condition, results of operations and cash flows could be adversely affected relative to other mining companies that have a more geographically diversified asset portfolio.

In addition, scientists have warned that increasing concentrations of greenhouse gases in the Earth's atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts and floods and other climatic events. For example, the State of California has experienced several years of increasingly more extreme drought and forest fires throughout the state. If these warnings are correct, and if any such climate-related weather and environmental effects were to detrimentally impact the areas where we or our customers operate, they could have an adverse effect on our business, financial condition and prospects.

***The operation or development of our facilities could be adversely affected by local communities and/or other stakeholders.***

Relationships with local communities and other stakeholders may impact the development or operations of the Project as well as other future projects. We may become impacted by the interests of local communities and other stakeholders, including in some cases, Indigenous peoples. Certain of these communities or other stakeholders may have or may develop interests or objectives which are different from, or even in conflict with, our objectives, including the use of our project lands and waterways near our facilities. Our relationships with the communities near the Project and other stakeholders are critical to the future success of the Project, as well as at any future development. There is an increasing level of public concern relating to the perceived effect of mining activities on the environment and on communities impacted by such activities. Publicity adverse to the Project, or the mining industry generally, could

------

have an adverse effect on our development plans or future operations and may impact relationships with the communities in which we ultimately operate and other associated stakeholders.

We may in the future, be subject to disputes with local communities, including Indigenous peoples, regarding the use of certain aspects of our assets, facilities and land and may in the future, be required to enter into settlement agreements providing for such use, on terms that include, among others, lump sum payments, royalty payments or restrictions on our business.

In addition, disputes surrounding Indigenous land claims regarding lands on or near our properties could interfere with future operations and/or result in additional operating costs or restrictions, as well as adversely impact the use and enjoyment of our real property rights with respect to our assets.

While we are committed to operating in a socially responsible manner, there can be no assurance that our efforts in this respect will mitigate this potential risk. All the foregoing could have a material adverse effect on our business, financial condition and results of operations, including, but not limited to, as a result of increased costs, reduced revenues, diversion of management attention, reputational harm, disruptions to our operations and other reasons.

***We currently plan to continue to invest significant amounts of capital in a variety of exploration activities, which involve many uncertainties and risks that could prevent us from realizing profits or may result in the total or partial loss of our investment.***

Our exploration and development activities may be delayed, more costly than anticipated or unsuccessful for many reasons, including declines in boric acid and its derivatives, lithium carbonate, HCl and gypsum, cost overruns, unanticipated financial, operational or political events, mechanical and technical difficulties, increases in operating cost structures, equipment and labor shortages, industrial actions or other circumstances which may result in the delay, suspension or termination of our exploration and development projects, the total or partial loss of our investment in such projects and activities and a material adverse effect on our results of operations, financial condition and prospects.

***Our future success depends on the continuing efforts of our management and key employees and our ability to attract and retain highly-skilled personnel and senior management.***

The responsibility of overseeing the day-to-day operations and the strategic management of our business depends substantially on our senior officers and our key personnel. Loss of such personnel may have an adverse effect on our performance. The success of our operations will depend upon numerous factors, many of which are beyond our control, including our ability to attract and retain additional key personnel in sales, marketing, commercial, engineering and technical support and finance. We currently depend upon a relatively small number of key persons to seek out and form strategic alliances and find and retain additional employees. Certain areas in which we operate are highly competitive regions and competition for qualified personnel is intense. We may be unable to hire suitable field personnel for our technical team or there may be periods of time where a particular position remains vacant while a suitable replacement is identified and appointed.

Our inability to hire and maintain suitable personnel could have a material adverse effect on us and could prevent us from effectively pursuing our business plan, including developing, growing, and operating our business profitably.

We also depend upon third parties, including consultants, engineers, suppliers and others, for their development, construction and operating expertise and expect to remain so for the foreseeable future. Our ability to continue conducting our activities is in large part dependent upon the efforts of third parties. Highly qualified consultants and engineers are expensive and difficult to attract and retain. We may need to engage additional third parties for new development projects, to establish mineral reserves through drilling, to carry out environmental and social impact assessments, to develop processes to extract boron and lithium and other materials, and to continue to develop the Project. If such parties' work is deficient or negligent or is not completed in a timely manner, it could have a material adverse effect on us. As a result, our use of services of consultants could have a material adverse effect on us and could prevent us from effectively pursuing our business plan.

***We will need to increase the size of our organization and we may be unable to manage our growth effectively.***

Our past growth has provided, and our future growth may create, challenges to our organization. Members of our management team possess significant experience and have previously carried out or been exposed to exploration, development and production activities. However, we have limited operating history and our ability to achieve our objectives depends on the ability of our directors, officers and management to implement current plans and respond to any unforeseen circumstances that require changes to those plans. The execution of our business plan will place demands on us and our management. In the future, we expect to hire and train new

------

personnel as we continue to grow and expand our operations. Our ability to recruit, assimilate, and maintain new personnel will be critical to our performance and we will be required to recruit additional personnel to achieve our business objectives. As a public company, we will need to support managerial, operational, financial and other resources. This growth may place significant strain on us. Successful growth is also dependent upon our ability to implement appropriate financial and management controls and systems and procedures. If we are unable to recruit additional personnel and effectively train, motivate, retain, and manage employees, or if we fail to manage these challenges effectively, our financial condition, business, and results of operations could be materially and adversely affected.

***Our directors and officers may in the future be in a position of a conflict of interest.***

Some of our directors and officers currently also serve as directors and officers of other companies involved in natural resource exploration, development and production, and any of our directors may in the future serve in such positions. As at the date of this report, none of our directors or officers serves as an officer or director of a minerals exploration, development or producing company nor possesses a conflict of interests with our business. However, there exists the possibility that they may in the future be in a position of a conflict of interest.

***We have experienced significant turnover in our senior management team and across our organization, and our failure to attract and retain qualified personnel, skilled workers and key officers could have an adverse effect on us.***

Our business may be adversely affected by recent turnover in our senior management team and board of directors which may create instability within the Company, which could disrupt and impede our day-to-day operations, internal controls and our ability to fully implement our business plan and growth strategy. In addition, management transition inherently causes some loss of institutional knowledge, which can negatively affect strategy and execution, and our results of operations and financial condition could be negatively impacted as a result. Competition for key management personnel is intense. If we fail to successfully attract and appoint permanent replacements with the appropriate expertise, we could experience increased employee turnover and harm to our business, results of operations, cash flow and financial condition. The search for permanent replacements could also result in significant recruiting and relocation costs, as well as increased salary and benefit costs. Like most businesses, our employees are important to our success and we are dependent in part on our ability to retain the services of our key management, operational, compliance, finance and administrative personnel. In order to compete and implement our growth strategy, we must attract, retain, and motivate employees, and turnover of senior management may make it difficult to retain qualified and skilled employees.

***We may acquire additional businesses or assets, form joint ventures or make investments in other companies in the future that may be unsuccessful and may harm our operating results and prospects.***

As part of our business strategy, we may pursue additional acquisitions of complementary businesses or assets. While we currently expect that any such acquisition would be funded with equity, the type of financing for any such acquisition will depend on circumstances existing at that time, including market conditions and our share price. If we are successful at identifying and making such acquisitions, integration of any acquired businesses or assets nevertheless involves many challenges, including a potential strain on our administrative and operational resources, unanticipated issues, expenses or liabilities, and difficulties in the assimilation of different corporate cultures and business practices. We may also seek to enter into joint ventures, pursue strategic alliances in an effort to leverage our existing operations and industry experience, increase our product offerings, expand our distribution and make investments in other companies. We do not have specific timetables for these potential activities and we cannot guarantee that we will be able to identify and complete suitable acquisitions or investments at reasonable prices, or that we will be successful in realizing any anticipated benefits from any future acquisitions or investments.

The success of any acquisitions, joint ventures, strategic alliances or investments will depend on our ability to identify, negotiate, complete and, in the case of acquisitions, integrate those transactions and, if necessary, obtain satisfactory debt or equity financing to fund those transactions. We may not realize the anticipated benefits of any acquisition, joint venture, strategic alliance or investments. We may not be able to integrate acquisitions successfully into our existing business, maintain the key business relationships of businesses we acquire, or retain key personnel of an acquired business, and we could assume unknown or contingent liabilities or incur unanticipated expenses.

Integration of acquired companies or businesses also may require management resources that otherwise would be available for ongoing development of our existing business. Any acquisitions or investments made by us also could result in significant write-offs or the incurrence of debt and contingent liabilities, any of which could harm our operating results. In addition, if we choose to issue equity as consideration for any acquisition, our shareholders may experience dilution.

***We could be subject to information technology system failures, network disruptions, and breaches in data security which could negatively affect our business, financial position, results of operations and cash flows.***

The efficiency and efficacy of our business and its operations depend heavily on the performance and availability of our computer and information systems, which we use to communicate, control and manage our operations and prepare our financial management and reporting information. As dependence on digital technologies is expanding, cyber incidents, including deliberate attacks and accidental cybersecurity events have been increasing worldwide. We face numerous and evolving cybersecurity risks that threaten the confidentiality, integrity and availability of our information systems and confidential information, including from diverse threat actors, such as state-sponsored organizations, opportunistic hackers and hacktivists, as well as through diverse attack vectors, such as social engineering/phishing, company insiders, suppliers or providers, and as a result of human or technological error, including misconfigurations, bugs, or other vulnerabilities in software and hardware. Computers, telecommunication and information systems are used to conduct our exploration and development activities, will be used to conduct our production activities and have become an integral part of our business. We use these systems to analyze and store financial and operating data, as well as to support our internal communications and interactions with business partners. Cyber-attacks could compromise our computer, telecommunications and information systems and result in additional costs as well as disruptions to our business operations or the loss of our data. Cyberattacks are expected to accelerate on a global basis in frequency and magnitude as threat actors are becoming increasingly sophisticated in using techniques and tools – including artificial intelligence – that circumvent security controls, evade detection and remove forensic evidence. As a result, we may be unable to detect, investigate, remediate or recover from future attacks or incidents, or to avoid a material adverse impact to our information systems, confidential information or business. A cyber-attack involving our information systems and related infrastructure, or those of our business partners, could disrupt our business and negatively impact our operations in a variety of ways. Our information systems and confidential information are vulnerable to a range of cybersecurity risks and threats, including malicious code embedded in open-source software, or misconfigurations, "bugs" or other vulnerabilities in commercial software that is integrated into our (or our suppliers' or service providers') IT systems, products or services. Although we maintain insurance policies, we cannot be certain that any or all of the costs and liabilities incurred in relation any cybersecurity attack or incident will be covered or that applicable insurance will be available to us in the future on economically reasonable terms or at all.

Given the size of our organization, we rely heavily on the use of, and services provided by third parties, including for a significant portion of our key cybersecurity risk management. Because we make extensive use of third-party suppliers and service providers, such as cloud services that support our internal and customer-facing operations, successful cyberattacks that disrupt or result in unauthorized access to third party information systems can materially impact our operations and financial results.

Such material risks and threats include, but are not limited to, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•impacts to availability of systems or data, e.g., operational disruption such as ransomware, even if no direct impact to information data is involved. For instance:

oan attack on the computers or information systems which control our mining operations could cause a temporary interruption of our production;

oa cyber-attack on our accounting , accounts payable or related information systems could expose us to liability to employees and third parties, or reputational risk, if their sensitive personal information is obtained;

opossible loss of material information, which in turn could delay productive processes and selling efforts, causing economic losses; and

oa cyber-attack on a service provider or their information systems which we rely could result in supply chain disruptions, which could delay or halt our major development projects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Non-malicious (e.g., unintentional) incidents that have an adverse impact on confidentiality, integrity or availability of information or systems resulting from human or system error or malfunction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•A third party or supply chain incident, e.g., incidents that impact our company due to an impact on a vendor, service provider, supply chain player, partner, or any other third party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Further material risks connected to aforementioned cybersecurity incidents include but are not limited to:

otheft, loss, or unauthorized disclosure of sensitive information,

ofinancial loss,

olegal and regulatory penalties or enforcement, and

odamage to our reputation.

## Risks Relating to Our Common Stock and CDIs
***Our largest stockholders control a significant percentage of our voting power and may be able to exert significant control over the direction of our business.***

Our largest stockholders, Bluescape Special Situations IV ("Bluescape"), Meridian Investments Corporation ("Meridian") and Ascend Global Investment Fund SPC for and on behalf of Strategic SP (together with Meridian, "Ascend"), hold a majority of our outstanding shares of common stock, approximately 68.7% of our outstanding shares as of August 31, 2025. If Meridian, Ascend and Bluescape were to choose to act together, they would be able to control all matters submitted to our stockholders for approval, as well as our management and affairs. For example, these parties, if they choose to act together, could control the election of directors and approval of any merger, consolidation or sale of all or substantially all of our assets. This concentration of ownership control may delay, defer or prevent a change in control, entrench our management or the board of directors, or impede a merger, consolidation, takeover or other business combination involving us that other stockholders may desire. These parties may have interests that are different than those of other stockholders. Meridian, Ascend and Bluescape also hold warrants to purchase up to an aggregate of 5,632,692 shares of Common Stock which, if exercised prior to their expiration date in March 2026, would increase their voting power and ability to exert control over our business.

***Exercise of our outstanding warrants will dilute the ownership interest of our existing stockholders or may otherwise depress the price of our Common Stock.***

On March 13, 2025, we issued warrants to purchase an aggregate of 5,632,692 shares of our Common Stock at an exercise price of $3.5507 per share to Bluescape and Ascend, which were immediately exercisable, (the "Restructuring Warrants"). The Restructuring Warrants expire on the first anniversary of their issuance. Additionally, in August 2024, we issued and sold warrants to purchase an aggregate of 463,770 shares of our Common Stock at an exercise price of $18.3563 per share, including warrants to purchase 231,885 shares of our Common Stock (the "Series A Warrants") and warrants to purchase 231,885 shares of our Common Stock (the "Series B Warrants"), which became initially exercisable on February 27, 2025. The Series A Warrants will expire on February 27, 2030 and the Series B Warrants will expire on February 27, 2027.

The exercise of some or all of such warrants will dilute the ownership interests of existing stockholders and increase the number of shares of Common Stock eligible for resale in the public market. Any sales in the public market of the shares of Common Stock issuable upon such exercise of such warrants, or the anticipation of such exercises and sales, could adversely affect the prevailing market prices of our Common Stock. Additionally, the existence of such warrants may encourage short selling by market participants because the exercise of such warrants could be used to satisfy short positions, or because the anticipated exercise of such warrants for shares of Common Stock could depress the price of our Common Stock.

***The market price and trading volume of our Common Stock and CDIs may be volatile and may be affected by economic conditions beyond our control.***

Our Common Stock is listed and publicly traded on Nasdaq, while our CDIs are listed and publicly traded on the Australian Securities Exchange ("ASX"). The market price of our Common Stock and CDIs may be highly volatile and subject to wide fluctuations. In addition, the trading volume of our Common Stock and CDIs may fluctuate and cause significant price variations to occur. If the market price of our Common Stock and CDIs declines, you may be unable to resell your CDIs or Common Stock at a competitive price. We cannot assure you that the market price of our Common Stock and CDIs will not fluctuate or significantly decline in the future. We cannot assure you that a trading market for our Common Stock or CDIs will be maintained.

Some specific factors that could negatively affect the price of our Common Stock and CDIs or result in fluctuations in their price and trading volume include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•actual or expected fluctuations in our prospects or operating results;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•changes in the demand for, or market prices for, borates, lithium, calcium chloride, gypsum, and other minerals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•additions or departures of our key personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•changes or proposed changes in laws, regulations or tax policy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•sales or perceived potential sales of our Common Stock by us or our directors, senior management or shareholders in the future;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•announcements or expectations concerning additional financing efforts;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•conditions in the U.S. and global financial markets, or in our industry in particular, or changes in general economic conditions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the other factors described in this "Risk Factors" section and elsewhere in this Annual Report.

In recent years, the stock markets generally have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry factors may significantly affect the market price of our Common Stock, regardless of our actual operating performance.

***We incur significant costs as a result of being publicly traded in both the United States and Australia.***

As our Common Stock is publicly traded in both the United States and Australia, we incur significant legal, accounting, insurance and other expenses related to compliance with applicable regulations. Our management and other personnel devote a substantial amount of time to these compliance initiatives, and we may need to continue to add additional personnel and develop our internal compliance infrastructure. Moreover, these rules and regulations increase our legal and financial compliance costs and make some activities more time consuming and costly. Furthermore, if we are unable to satisfy our obligations as a public company in the United States, we could be subject to delisting of our Common Stock, fines, sanctions, and other regulatory action and potentially civil litigation.

Our Common Stock is publicly traded on the ASX in the form of CDIs. As a result, we must comply with the listing rules of the ASX (the "ASX Listing Rules"). We have policies and procedures that we believe are designed to provide reasonable assurance of our compliance with the ASX Listing Rules. If, however, we do not follow those procedures and policies, or they are not sufficient to prevent non-compliance, we could be subject to liability, fines and lawsuits. These laws, regulations and standards are subject to varying interpretations and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of management's time and attention from revenue generating activities to compliance activities. If, notwithstanding our efforts to comply with new laws, regulations and standards, we fail to comply, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

***We incur increased costs as a result of operating as a U.S. listed public company, and our management is required to devote substantial time to new compliance initiatives and corporate governance practices.***

As a U.S. listed public company we incur, and particularly after we are no longer an "emerging growth company" we expect to incur, significant additional legal, accounting, and other expenses. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"), the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act"), the listing requirements of Nasdaq, and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. We expect that we will need to hire additional accounting, finance, legal, and other personnel in connection with our efforts to comply with the requirements of being a public company, and our management and other personnel will need to devote a substantial amount of time towards maintaining compliance with these requirements. These requirements increase our legal and financial compliance costs and make some activities more time-consuming and costly. In addition, we expect that the rules and regulations applicable to us as a public company may make it more difficult and more expensive for us to obtain directors' and officers' liability insurance, which could make it more difficult for us to attract and retain qualified members of our board of directors or executive officers.

We are subject to Section 404 of the Sarbanes-Oxley Act and the related rules of the SEC, which generally require our management and independent registered public accounting firm to report on the effectiveness of our internal control over financial reporting. Beginning with our 2023 Annual Report on Form 10-K, Section 404 required an annual management assessment of the effectiveness of our internal control over financial reporting. However, for so long as we remain an emerging growth company as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), we intend to take advantage of certain exemptions from various reporting requirements that are applicable to public companies that are not emerging growth companies, including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404. Once we are no longer an emerging growth company or, if prior to such date, we opt to no longer take advantage of the applicable exemption, we will be required to include an opinion from our independent registered public accounting firm on the effectiveness of our internal control over financial reporting.

------

***An active trading market for our Common Stock and CDIs may not be sustained and the trading price for our Common Stock and CDIs may fluctuate significantly.***

Shares of our Common Stock are able to be traded by the public on Nasdaq, and our CDIs are able to be traded by the public on the ASX. However, a liquid public market for our Common Stock or CDIs may not be sustained, which means you may experience a decrease in the value or trading price of the shares of our Common Stock and our CDIs (which is based upon the value of our Common Stock), regardless of our operating performance. If a liquid public market for our Common Stock does not sustain, then the value of our CDIs, which is based upon the value of our Common Stock, is also likely to decrease in value. In the past, following periods of volatility in the market price of a company's securities, shareholders often instituted securities class action litigation against that company. If we were involved in a class action suit, it could divert the attention of directors or senior management and, if adversely determined, could have a material adverse effect on our results of operations and financial condition.

***Because we do not anticipate paying dividends on our Common Stock in the foreseeable future, capital appreciation, if any, will be your sole source of gain on our Common Stock and CDIs.***

Our former parent company, ABR, did not declare any dividends during fiscal years 2019, 2020 or 2021, and we have not declared dividends since, and we do not anticipate that we will do so in the foreseeable future. We currently intend to retain future earnings, if any, to finance the development of our proposed business. Dividends, if any, on our outstanding Common Stock and CDIs will be declared by and subject to the discretion of our Board of Directors on the basis of our earnings, financial requirements and other relevant factors, and subject to Delaware and federal law. We cannot assure you that our Common Stock and CDIs will appreciate in value. You may not realize a return on your investment in our Common Stock and CDIs and you may even lose your entire investment in our Common Stock and CDIs.

***If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse or misleading opinion regarding our stock, the market price and trading volume of our Common Stock and CDIs could decline.***

The trading market for our Common Stock and CDIs will be influenced by the research and reports that U.S. securities or industry analysts publish about us or our business. Securities and industry analysts may discontinue research on us, to the extent such coverage currently exists, or in other cases, may never publish research on us. If no or few U.S. securities or industry analysts commence coverage of us, the trading price for our Common Stock and CDIs would be negatively affected. In the event securities or industry analysts initiate coverage, if one or more of the analysts who cover us downgrade our Common Stock and CDIs Stock or publish adverse or misleading research about our business, the market price of our Common Stock and CDIs would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, demand for our Common Stock and CDIs could decrease, which might cause our price and trading volume to decline. In addition, research and reports that Australian securities or industry analysts may, initiate or may continue to, publish about us, our business or our Common Stock may impact the market price of our Common Stock and CDIs.

***We are an "emerging growth company" and "smaller reporting company" and are able to avail ourselves to reduced disclosure requirements applicable to emerging growth companies and small reporting companies, which may make our Common Stock and CDIs less attractive to investors and, as a result, adversely affect the price of our Common Stock and CDIs and result in a less active trading market for our Common Stock and CDIs.***

We are an "emerging growth company" as defined in the JOBS Act and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. For example, we have elected to rely on an exemption from the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act relating to internal control over financial reporting, and we will not provide such an attestation from our auditors.

We may avail ourselves of these disclosure exemptions until we are no longer an "emerging growth company." We cannot predict whether investors will find our Common Stock and CDIs less attractive because of our reliance on some or all of these exemptions. If investors find our Common Stock and CDIs less attractive, it may adversely affect the price of our Common Stock and CDIs and there may be a less active trading market for our Common Stock and CDIs.

We will cease to be an "emerging growth company" upon the earliest of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the last day of the fiscal year during which we have total annual gross revenues of US$1,235,000,000 (as such amount is indexed for inflation every five years by the SEC) or more;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the last day of our fiscal year following the fifth anniversary of the completion of our first sale of common equity securities pursuant to an effective registration statement under the Securities Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the date on which we have, during the previous three-year period, issued more than US$1,000,000,000 in non-convertible debt; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the date on which we are deemed to be a "large accelerated filer," as defined in Rule 12b-2 of the Exchange Act, which would occur if the market value of our Common Stock that are held by non-affiliates exceeds US$700,000,000 as of the last day of our most recently completed second fiscal quarter.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. We have elected to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, we must adopt the new or revised standard at the time other non-emerging growth public companies adopt the new or revised standard. This may make comparison of our financial statements with an emerging growth company which has opted to use the extended transition period difficult or impossible because of the potential differences in accounting standards used. Additionally, the cost to implement new or revised financial accounting standards may be more costly and difficult as we will be required to implement such standards during periods when a significant number of companies are doing so, making third-party resources scarce and/or costly, and when interpretations of the new standards may still be emerging.

We are also a smaller reporting company, and we will remain a smaller reporting company until, as of fiscal year end, we determine that either (1) our annual revenues are at least $100 million and our voting and non-voting common stock held by non-affiliates is at least $250 million measured on the last business day of our most recent second fiscal quarter or (2) our voting and non-voting common stock held by non-affiliates is at least $700 million measured on the last business day of our most recent second fiscal quarter. Similar to emerging growth companies, smaller reporting companies are able to provide simplified executive compensation disclosure, are exempt from the auditor attestation requirements of Section 404, and have certain other reduced disclosure obligations, including, among other things, being required to provide only two years of audited financial statements and not being required to provide selected financial data, supplemental financial information or risk factors.

***If we experience any material weaknesses in the future or otherwise fail to develop or maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our Common Stock and CDIs.***

Effective internal control over financial reporting is necessary for us to provide reliable financial reports, prevent fraud and operate successfully as a public company. If we cannot provide reliable financial reports or prevent fraud, our reputation and operating results would be harmed. As a result of being a public company, we are required, under Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting, which began with our 2023 Annual Report on Form 10-K. This assessment includes disclosure of any material weaknesses identified by our management in our internal control over financial reporting. If we identify one or more material weaknesses in our internal control over financial reporting during the evaluation and testing process, we may be unable to conclude that our internal controls are effective. We have not been, and will not be, audited or subject to an assessment of internal control over financial reporting until we are no longer an emerging growth company. There can be no assurance that no material weakness or significant deficiency will be identified once such an audit or assessment of internal control over financial reporting is completed.

Additionally, when we cease to be an "emerging growth company" under the federal securities laws, our independent registered public accounting firm may be required to express an opinion on the effectiveness of our internal controls. If we are unable to confirm that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an unqualified opinion on the effectiveness of our internal controls, we could lose investor confidence in the accuracy and completeness of our financial reports, which could cause the price of our Common Stock and CDIs to decline.

***Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.***

As a public company, we are subject to the periodic reporting requirements of the Exchange Act. We designed our disclosure controls and procedures to provide reasonable assurance that information we must disclose in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures, no matter how

------

well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.

***Our Certificate of Incorporation and Bylaws contain anti-takeover provisions that could delay or discourage takeover attempts that shareholders may consider favorable and may prevent attempts by our shareholders to replace or remove our current management.***

Our Certificate of Incorporation and Bylaws contain provisions that could delay or prevent a merger, acquisition, or other change in control of our company that shareholders may find favorable, including transactions in which shareholders might otherwise receive a premium for their shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our Common Stock, thereby depressing the market prices for our Common Stock. In addition, these provisions could also make it difficult for shareholders to elect directors who are not nominated by the current members of our Board of Directors or take other corporate actions, including effecting changes in our management. These provisions include, among other things, that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the ability of our Board to issue shares of Preferred Stock and to determine the price and other terms of those shares, including preferences and voting rights, without shareholder approval, which could be used to significantly dilute the ownership of a hostile acquirer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•allowing only our Board to fill director vacancies, which prevents shareholders from being able to fill vacancies on our Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a prohibition on shareholders action by written consent, which forces shareholder action to be taken at an annual or special meeting of our shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a requirement that special meetings of our shareholders may be called only by (i) our Board or (ii) our secretary, following receipt of one or more written demands to call a special meeting from shareholders of record who own, in the aggregate, at least 25% of the voting power of our outstanding shares then entitled to vote on the matter or matters to be brought before the proposed special meeting that complies with the procedures for calling a special meeting set forth in our Bylaws, which may inhibit the ability of an acquirer to require the convening of a special meeting of our shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a requirement for the affirmative vote of holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of the voting stock, voting together as a single class, to amend the certain provisions of our Certificate of Incorporation or our Bylaws, which may inhibit the ability of an acquirer to effect such amendments to facilitate an unsolicited takeover attempt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the ability of our Board to amend our Bylaws, which may allow our Board to take additional actions to prevent an unsolicited takeover and inhibit the ability of an acquirer to amend the Bylaws to facilitate an unsolicited takeover attempt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•advance notice procedures with which shareholders must comply to nominate candidates to our Board or to propose matters to be acted upon at a shareholders' meeting, which may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer's own slate of directors or otherwise attempting to obtain control of our company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a prohibition of cumulative voting in the election of our Board, which would otherwise allow less than a majority of shareholders to elect director candidates.

We are also subject to Section 203 of the Delaware General Corporation Law (the "DGCL"), which prevents us from engaging in a business combination, such as a merger, with an interested shareholder (i.e., a person or group that acquires at least 15% of our voting stock) for a period of three years from the date such person became an interested shareholder, unless (with certain exceptions) the business combination or the transaction in which the person became an interested shareholder is approved in a prescribed manner.

***Raising additional capital could adversely affect the voting power or value of our Common Stock and CDIs.***

Until such time, if ever, as we can generate substantial revenue, we may finance our cash needs through a combination of equity offerings or the issuance of debt instruments or other securities convertible into Common Shares. We do not currently have any committed external source of funds. In addition, we may seek additional capital due to favorable market conditions or strategy considerations, even if we believe that we have sufficient funds for our current or future operating plans.

------

We cannot predict the size or price of future issuances of Common Shares or the size or terms of future issuances of debt instruments or other securities convertible into Common Shares, or the effect, if any, that future issuances and sales of our securities will have on the market price of the Common Shares. To the extent that we raise additional capital through the sale of equity or convertible debt securities, investors' ownership interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common shareholder including voting rights.

Our Certificate of Incorporation authorizes us to issue, without the approval of our shareholders, one or more classes or series of Preferred Stock having such designations, preferences, limitations and relative rights, including preferences over our Common Stock and CDIs respecting dividends and distributions, as our Board of Directors may determine. For example, we might grant holders of Preferred Stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. The terms of one or more classes or series of Preferred Stock could adversely impact the voting power or value of our Common Stock and CDIs. Similarly, the repurchase or redemption rights or liquidation preferences we might grant to holders of Preferred Stock could affect the residual value of our Common Stock.

Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, or declaring dividends.

***We have in the past and may again in the future receive a notice of the failure to satisfy a continued listing rule from Nasdaq.***

Our Common Stock is listed on Nasdaq. Nasdaq maintains several requirements for continued listing of our Common Stock, one of which is the maintenance of a minimum closing bid price of $1.00. In September 2024, we received written notice from Nasdaq notifying us that the bid price for our common stock had closed below the $1.00 Bid Price Requirement for continued inclusion on The Nasdaq Global Select Market. Although we regained compliance with the Bid Price Requirement in a timely manner, there is no guarantee we will in the future be able to maintain compliance with the Bid Price Requirement or any other Nasdaq listing standard, which would subject our Common Stock to delisting from Nasdaq.

If our Common Stock is delisted from Nasdaq in the future based on any continued listing requirement, it is unlikely that we will be able to re-list our common stock on another national securities exchange and, as a result, we expect our securities would be quoted on an over-the-counter market. If this occurs, we could face significant material adverse consequences, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a limited availability of market quotations for our Common Stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a determination that our Common Stock is a "penny stock" which will require brokers trading in our Common Stock to adhere to more stringent rules, which could result in a reduced level of trading activity in the secondary trading market for our Common Stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•more limited news and analyst coverage for us; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a decreased ability to issue additional securities or obtain additional financing in the future.

Delisting also could result in, among other things, a loss of investor confidence or interest in strategic transactions or opportunities, us being subject to regulation in each state in which we offer our securities, and difficulty in recruiting and retaining personnel through equity incentive awards.

***Sales by our existing shareholders can reduce the market price of our Common Stock and CDIs.***

Sales of a substantial number of our Common Stock in the public market could occur at any time. Such sales, or any market perception that substantial holders of our Common Stock intend to sell our Common Stock, could reduce the market price of our Common Stock and CDIs. If this occurs, it could impair our ability to raise additional capital through the sale of securities.

## *We are a holding company and, as such, we depend on our subsidiaries to generate cash to fund our operations and expenses.* 
We are a holding company and essentially all of our assets are the capital stock of our subsidiaries. As a result, our investors are subject to the risks attributable to our subsidiaries. As a holding company, we conduct all of our business through our subsidiaries. Therefore, our ability to fund and conduct our business, service our debt and pay dividends, if any, in the future will principally depend on the ability of our subsidiaries to generate sufficient cash flow to make upstream cash distributions to us. Our subsidiaries are separate legal entities, and although they are wholly-owned and controlled by us, they have no obligation to make any funds available to us, whether in the form of loans, dividends or otherwise. The ability of these entities to pay dividends and other distributions will depend on their operating results and will be subject to applicable laws and regulations which require that solvency

------

and capital standards be maintained by such companies and contractual restrictions contained in the instruments governing any debt obligations. In the event of a bankruptcy, liquidation or reorganization of any of our material subsidiaries, holders of indebtedness and trade creditors may be entitled to payment of their claims from the assets of those subsidiaries before us.

***Our Bylaws designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our shareholders, which could limit our shareholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.***

These choice-of-forum provisions may limit a shareholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and such persons. Alternatively, if a court were to find these provisions of our Bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or operating results.

## Item 1C. Cybersecurity

## Description of Processes for Assessing, Identifying, and Managing Cybersecurity Risks
Cybersecurity is integrated within the Company's Enterprise Risk Management process, which is the Company's systematic approach to identifying, managing and assessing major risk and safeguards, including cybersecurity. We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity, and availability of our critical systems and information.

Our cybersecurity risk management program is integrated into our overall risk management program, and shares common methodologies, reporting channels and governance processes that apply across the risk management program to other legal, compliance, strategic, operational, and financial risk areas. Despite our efforts we put into maintaining a high level of cybersecurity, there can be no assurance that our cybersecurity risk management program and processes, including our policies, controls or procedures, will be fully implemented, complied with or effective in protecting our systems and information.

Key elements of our cybersecurity risk management program include but are not limited to the following:

***Risk Assessment***

We periodically conduct assessments of cybersecurity risks to identify potential vulnerabilities and threats to our systems and data. These risk assessments are designed to help identify material risks from cybersecurity threats to our critical systems and information.

------

***Security Team***

We have established a security team which is principally responsible for managing (i) our cybersecurity risk assessment processes, (ii) our security controls, and (iii) our response to cybersecurity incidents.

***Protection Measures***

We implement and maintain cybersecurity controls, including firewalls, access controls, and intrusion detection systems, to safeguard our systems and data from unauthorized access, use, or disclosure. Furthermore, we use external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security processes.

***Incident Detection and Response***

We have established a cybersecurity incident response plan that includes procedures for responding to relevant cybersecurity incidents. These protocols include incident response plans and escalation procedures to minimize the impact of potential breaches.

***Cybersecurity Training and Awareness***

All new hires receive cybersecurity awareness training. All employees, including incident response personnel and senior management, receive periodic training and are periodically subject to evaluations to confirm their cybersecurity knowledge and awareness.

***Third-Party Risk Management***

We have implemented a third-party risk management process for key service providers based on our assessment of their criticality to our operations and respective risk profile.

## Material Cybersecurity Incidents
We have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected us, including our operations, business strategy, results of operations, or financial condition. We face risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. See "Risk Factors" within this report when evaluating our business and related risk.

## Cybersecurity Governance
The Board of Directors is responsible for overseeing cybersecurity, information security, and information technology risks, as well as management's actions to identify, assess, mitigate, and remediate those risks. As part of its program of regular risk oversight, the Audit Committee assists the Board of Directors in exercising oversight of the Company's cybersecurity, information security, and information technology risks. Periodically, the Audit Committee reviews and discusses with the Chief Financial Officer, who leads our cybersecurity program, the Company's policies, procedures, and practices with respect to cybersecurity, information security and information and operational technology, including related risks.

Recognizing the importance of cybersecurity to the success and resilience of our business, the Board of Directors considers cybersecurity to be an important aspect of corporate governance. To facilitate effective oversight, our Chief Financial Officer holds discussions on cybersecurity risks and the effectiveness of cybersecurity measures as necessitated by emerging material cyber risks.

Our management team, including the Chief Financial Officer, is responsible for assessing and managing our material risks from cybersecurity threats. The team has primary responsibility for our overall cybersecurity risk management program and supervises both our internal cybersecurity personnel and our retained external cybersecurity consultants.

Given the size of the Company, we do not employ individuals with significant experience and relevant backgrounds in information security, cyber risk management, and cyber incident response. However, we contract with third-party vendors who have these backgrounds. These backgrounds include relevant degrees, certifications, and relevant work experience, including in roles responsible for cybersecurity oversight in entities similar to us, and our Chief Financial Officer relies on the expertise provided by these third-parties in carrying out his cybersecurity responsibilities.

------

Our management team takes steps to stay informed about and monitor efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through various means, which may include threat intelligence and other information obtained from governmental, public or private sources, including external consultants engaged by us; and alerts and reports produced by security tools deployed in our information technology environment.

## Item 3. Legal Proceedings
Except as disclosed in Note 14–*Commitments and Contingencies* in the consolidated financial statements included in Item 8 of this Form 10-K, as of the date of this filing, we are not a party to any material pending legal proceedings, nor are we aware of any material civil proceeding or government authority contemplating any legal proceeding, and to our knowledge, no such proceedings by or against us have been threatened. We anticipate that we and our subsidiaries may from time to time become subject to various claims, legal proceedings, governmental inspections, audits, or investigations arising in the ordinary course of business. It is not feasible to predict the outcome of any such proceedings, and we cannot assure you that their ultimate disposition will not have a material adverse effect on our business, financial condition, cash flows or results of operations.

## Item 4. Mine Safety Disclosures
Not applicable as we do not currently operate any mines subject to the U.S. Federal Mine Safety and Health Act of 1977.

------

# PART II

## Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

## *Market for Common Stock* 
Our Common Stock is currently listed on Nasdaq under the symbol "FEAM."

The closing price of our Common Stock on September 28, 2025 was [$3.72] per share. As of that date, there were [17] holders of record of our Common Stock according to Computershare Trust Company, N.A. The actual number of stockholders is greater than these numbers and includes holders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. These numbers of active holders of record also do not include holders whose shares may be held in trust by other entities.

## *Dividend Policy* 
We have not paid any cash dividends on our Common Stock to date. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial condition. The payment of any cash dividends will be subject to the discretion of the Board of Directors.

## *Unregistered Sale of Equity Securities* 
Except as previously disclosed on Current Reports on Form 8-K filed with the SEC on August 28, 2024, September 26, 2024, January 14, 2025, March 5, 2025 and March 13, 2025, and in our Quarterly Report on Form 10-Q filed with the SEC on May 15, 2025, there was a single unregistered sale of equity securities for the year ended June 30, 2025, as further described below.

On July 15, 2025, the Company issued a total of 20,000 shares of Common Stock with a fair value on the issuance date of $3.55 per share to an investor in exchange for a market awareness campaign and various public and investor relations services. The shares were sold in a private offering to an investor that was acquiring the shares for its own account. The offering, therefore, was exempt from registration under the Securities Act of 1933 pursuant to Section 4(2) of the Securities Act.

## *Purchases of Equity Securities by the Issuer and Affiliated Purchasers* 
None.

**Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations**

*The following Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") summarizes the significant factors affecting the operating results, financial condition, liquidity and capital resources, and cash flows of our Company for the years ended June 30, 2025 and 2024. This MD&A should be read in conjunction with, and is qualified in its entirety by, the consolidated financial statements, the accompanying notes thereto and other financial information included in this Annual Report on Form 10-K (the "Annual Report"). Except for historical information, this MD&A contains various forward-looking statements that involve risks, uncertainties and assumptions and other important factors and are based upon judgments concerning various factors beyond our control. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of many factors, including those discussed under "Item 1A-Risk Factors" and elsewhere in this Annual Report, any of which could cause the Company's actual results, performance or achievements, or industry results, to differ materially from any future results, performance or achievements expressed or implied by such forward-looking statements. All forward-looking statements speak only as of the date on which they are made. We undertake no obligation to update such statements to reflect events that occur or circumstances that exist after the date on which they are made. Additionally, you should refer to the "Cautionary Note Regarding Forward-Looking Statements." References within this MD&A to the "Company," "we," "our," and "us," refer to 5E Advanced Materials, Inc., and its subsidiaries.*

## Overview
5E Advanced Materials, Inc. is a development stage company focused on becoming a vertically integrated global leader and supplier of refined borates and advanced boron derivative materials whose mission is to enable decarbonization, increase food security, and ensure domestic supply of critical materials. Our business strategy and objectives are to develop capabilities ranging from upstream extraction and product sales of borates, calcium-based co-products, and potentially other byproducts such as lithium carbonate, to downstream advanced boron material processing and development. Our vision is to safely process borates and other industrial minerals through sustainable best practices and a continuous improvement mindset. We hold 100% of the rights through ownership and lode claims filed with the United States Bureau of Land Management in the 5E Boron Americas (Fort Cady) Complex (the "Project") located in southern California through our wholly owned subsidiary 5E Boron Americas LLC (formerly Fort Cady (California) Corporation ("5EBA")). Our Project is underpinned by boron reserves and lithium resource, with the boron being contained in a conventional boron mineral known as colemanite. In 2022, our facility was designated as Critical Infrastructure by the U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency. We currently operate our small-scale facility (the "SSF") at the Project, which provides data and information necessary for us to ultimately establish a commercial-scale facility (the "Commercial Scale Facility") at the Project.

We believe the Project represents one of the most compelling domestic critical material projects in the United States as a strategically located operation that targets stable long-term demand, with a defined pathway to production and a low-cost, high margin and profitable financial profile.

## Recent Developments
*Preliminary Feasibility Study, Technical Report Summary, Capital Estimate and Timeline to Final Investment Decision*

In August 2025, we issued our Preliminary Feasibility Study ("PFS") prepared in accordance with Regulation S-K 1300, which focuses on Phase 1 development of our Fort Cady Project to develop a 130,000 short ton per annum boric acid plant. We believe the PFS demonstrates a world-class resource, management's firm understanding and direction for the business, which can position the Company to achieve profitability, generate cash flow, and reduce risk.

Due to the current favorable market backdrop and growing importance of critical materials, we continue to focus primarily on further defining our boron reserves, and to work towards developing a commercial-scale commercial facility for the production of borates, calcium chloride and gypsum. A focus on boron extraction and related end markets is aligned with our mission to become a global leader in enabling industries addressing decarbonization, food security, national defense and production of domestic supply and our focus on high value in use materials and applications.

The PFS was based upon converting approximately 41% of our total mineral resource and established approximately 5.3 million short tons of boric acid reserves with an average grade of 8.03% (B2O3) and an initial 39.5 year life of mine utilizing an in-situ leaching mining method. The PFS allows for optionality for future expansion phases to develop the remaining portions of our total resource and future endeavors into value added advanced boron derivatives.

------

The financial model for the economic analysis included in the PFS was based upon a third-party preliminary market study which evaluated future supply and demand thematics for the boric acid market, as well as capital estimates developed by our EPC firm, Fluor Enterprises, Inc. ("Fluor") and Miocene, Inc. ("Miocene"). The PFS included a capital estimate of approximately $367 million, a 15% contingency of approximately $55 million, and owner's costs of approximately $13 million, for an aggregate capital estimate of approximately $435 million. The capital estimate includes the anticipated costs for a natural gas Combined Heat & Power ("CHP") COGEN facility that will power Phase 1 of the Project. The estimated accuracy range for the capital estimate is ±25%, which is consistent with industry standards for an Association for Advancement of Cost Engineering Class 4 estimate for projects at the PFS stage. However, our capital estimate is supported by a comprehensive suite of engineering deliverables, including process flow diagrams, simulation and material balance data, equipment lists, preliminary design documentation, and advanced vendor testing, all of which contribute to a well-substantiated capital cost basis.

We will continue to operate the SSF while we stage gate to FEL-3 engineering for Phase 1 of the commercial-scale complex. FEL-3 engineering is expected to provide the necessary estimates to publish a final feasibility study and reach a final investment and construction decision for Phase 1 of the proposed commercial-scale complex during the middle of calendar year-2026. Based upon progress to date, we are now targeting to reach initial commercial production from Phase 1 in the second-half of calendar year 2028.

Although our PFS focused on Phase 1 of commercial production, we have retained optionality for Phase 2 and Phase 3, at which point full operation would include 450,000 short tons of boric acid.

*Wellfield*

During July 2025, we converted two of our existing vertical injection recovery wells to horizontal-side tracks where each well now extends approximately 1,500 feet into high grade colemanite zones of the Project. The mine plan incorporated into the PFS contemplates the installation of 27 horizontal wells and the use of jet pumps for artificial lift. Over the next several months, we plan to operate these newly drilled horizontal injection recovery wells to refine our operational strategy for the proposed commercial-scale wellfield and to confirm expectations related to head grade. We expect to submit a final mine plan to the EPA for review based on the performance of the horizontal-side track wells.

## Fiscal Year 2025 Highlights and Future Considerations
***Operational Highlights***

*Operational Update*

During the first fiscal quarter of the year, we optimized and steadied production rates of boric acid at one short ton per day at the SSF and successfully programmed crystallization to operate in an automated mode such that distillation occurred based on feed concentration, improving both boric acid consistency, yield and quality. During this time, the SSF's belt filter spray nozzle systems were optimized to maintain sulfur content below 100 ppm, which is lower than levels specified by customers in our qualification program. Also during this time, we began to remove metal salts as calcium levels and metal salts had lagged boric acid leach rates to this point. Calcium content increased to greater than 20,000 ppm, necessitating the production of a calcium-based byproduct.

During the second fiscal quarter, we continued to optimize plant-level production rates and streamlined overall operations and our production process. Such efforts resulted in operating cost reductions and an improvement in the quality and consistency of our boric acid production.

During the third fiscal quarter, we focused our efforts on obtaining plant data to inform our byproduct selection, which included the considerations of solution feed profiles that inform raw material utilizations that drive operating expenses, which enabled us to have a more refined view of our future capital needs and operating expense profile. We have tested and produced samples of a 38% calcium chloride solution and a calcium-based product that we believe are representative of what could be produced on a commercial scale, and samples of these products have been provided to potential future customers. We continue to evaluate our byproduct selection, including consideration for the potential to modulate production of both a calcium-based byproduct and calcium chloride to maximize the future economics of the Project.

During the final fiscal quarter of the year, we focused our efforts on customer qualification by shipping product samples to a diverse group of potential customers, while simultaneously carrying out tests and activities aimed at optimizing our future wellfield design, improving wellfield head-grade, and optimizing our process for crystallization of boric acid. For the foreseeable future, we anticipate maintaining boric acid production rates of one short ton per day while the SSF continues to provide the necessary data to

------

inform and refine the design of the Commercial-Scale Facility, explore ways to optimize our wellfield design and related capital costs, and progress our customer qualification program, while striving to minimize liquidity impacts of the continued operation of the SSF. We believe that the information, data and operating results that have come, and will come, from the operation of the SSF will enable us to design the most efficient commercial-scale facility with optimized project economics.

*Commercial Team Strategic Hires*

In October 2024, Mark Zamek became our Vice President of Commercial Products, and Kenneth Hoo became our Vice President of Commercial Products - APAC. Mr. Zamek has over 20 years of direct industry experience, having held various senior roles across sales and marketing functions at the largest global borate producers. Most recently, Mr. Zamek served as a consultant for Eti Maden, where he advised the U.S.-focused boron operations on commercial strategy and market expansion initiatives. Prior to that, Mr. Zamek served in numerous strategic sales and marketing roles for over twenty years with Rio Tinto's U.S. Borax, most recently as Key Global Accounts Manager where he was responsible for managing the company's largest global borates contract.

Mr. Hoo has over 17 years of borates industry experience, having held several sales roles at the largest global borate producers, as well as consumers. Most recently, Mr. Hoo served as a Sales Manager at Rio Tinto Group, where he specialized in a variety of products, notably borates. Prior to that, Mr. Hoo served in numerous strategic sales roles at borate producers where he accumulated APAC supply chain and logistics expertise while focusing on developing commercial relationships in the Asian market.

We believe that the additions of Mr. Zamek and Mr. Hoo to our team will progress our vision of becoming a leading global supplier of borates and other industrial materials.

*Commercial Strategy*

During the second fiscal quarter of the year, we met a key milestone through the delivery of our first truckload of boric acid super sacks to a U.S. customer. During the second half of fiscal year 2025, approximately 14 customers successfully qualified our boric-acid product, and additional customers have requested product or are in advanced phases of the testing process. Customers that qualified our product represent a diverse group of industries and market segments such as specialty glass, textile fiberglass, ceramics, insulation, agriculture, defense and chemicals. Testing programs to date have included laboratory evaluation, field trials, and truckload-scale shipments. During April 2025, samples of boric acid that we supplied to a global specialty glass manufacturer successfully produced glass during qualification trials against other suppliers, with results showing that our boric acid performed as well as or better than the product of other suppliers across a variety of attributes of comparison. During August 2025, we packaged boric acid at our Project location and shipped it in an ocean freight container where it completed a 20-day international transit to Taiwan to a major global specialty glass manufacturing facility. Upon receipt, our product passed a handling trial and met all required specifications. The successful trials advance our customer onboarding and qualification process, and we believe demonstrates that our boron production is of the necessary quality to meet the rigorous standards of the specialty glass market. As part of the next phase of the broader qualification process, we plan to ship larger quantities of boric acid for production scale evaluation. We are currently in the process of negotiating contracts for a portion of our initial boric acid production in commercial Phase 1.

This progress supports the Company's strategy to build a multi-market customer base across multiple high value sectors. We believe this progress highlights its continued momentum toward building commercial relationships and advancing our operational and strategic objectives.

*Reduction in Workforce*

During November 2024, we undertook a strategic reduction in workforce (the "Reduction in Force"), which reduced our company-wide headcount by approximately 40% with the goal of optimizing our team, reducing fixed and variable operating costs and increasing our efficiency. We estimate that this initiative allowed us to save approximately $1.1 million in operating expenditure during the second half of fiscal year 2025.

***Financing Highlights***

*August 2024 Equity Offering*

On August 27, 2024, we completed an offering (the "August 2024 Equity Offering") of (i) 231,884 shares (the "Shares") of our common stock, par value $0.01 per share ("Common Stock"), (ii) Series A warrants to purchase up to an aggregate of up to 231,885

------

shares of Common Stock (the "Series A Warrants") and (iii) Series B warrants to purchase an aggregate of 231,885 shares of Common Stock (the "Series B Warrants", and collectively with the Series A Warrants, the "2024 Warrants"). The Shares and 2024 Warrants were offered and sold on a combined basis for consideration equating to $17.25 for one Share and two 2024 Warrants. The exercise price for each of the 2024 Warrants is $18.3563 per share.

The Series A Warrants and the Series B Warrants became exercisable on February 27, 2025. The Series A Warrants will expire on February 27, 2030 and the Series B Warrants will expire on February 27, 2027. The 2024 Warrants contain standard adjustments to the exercise price including for stock splits, stock dividends, rights offerings and pro rata distributions. The 2024 Warrants also include certain rights upon the occurrence of a "fundamental transaction" (as described in the warrants), including the right of the holder thereof to receive from the Company or a successor entity the same type or form of consideration (and in the same proportion) that is being offered and paid to the holders of Common Stock in such fundamental transaction in the amount of the Black Scholes value (as described in the respective warrant agreement) of the unexercised portion of the 2024 Warrants on the date of the consummation of such fundamental transaction. The 2024 Warrants include cashless exercise rights to the extent the resale of the shares of Common Stock underlying the 2024 Warrants is not registered under the Securities Act.

The net proceeds to us for the August 2024 Equity Offering were approximately $3.0 million after deducting the placement agent's fees and other offering expenses payable by us.

*September 2024 Notes Offering*

On September 16, 2024, we entered into a third amendment ("Amendment No. 3") to a January 2024 amended and restated note purchase agreement (as described in Note 7–*Debt*, of Item 8 of this Annual Report, the "January 2024 Amended and Restated Note Purchase Agreement") and agreed, among other things, to (i) issue and sell new senior secured convertible notes in substantially the same form and under the same terms as convertible notes issued in June of 2024 (as described in Note 7–*Debt* of Item 8 of this Annual Report, the "June 2024 Notes"), in an aggregate principal amount of $6.0 million (the "September 2024 Notes") to Bluescape Special Situations IV ("Bluescape"), Meridian Investments Corporation ("Meridian") and Ascend Global Investment Fund SPC for and on behalf of Strategic SP (together with Meridian, "Ascend"), and (ii) amend and restate the January 2024 Amended and Restated Note Purchase Agreement in the form attached as Annex A to Amendment No. 3 (the "September 2024 Amended and Restated Note Purchase Agreement"). The net proceeds to us for the September 2024 Notes were approximately $5.5 million after deducting issuance costs and fees payable by us.

*January 2025 Notes Offering*

On January 14, 2025, we entered into a fourth amendment ("Amendment No. 4") to the January 2024 Amended and Restated Note Purchase Agreement and agreed, among other things, to (i) issue and sell new senior secured convertible notes in substantially the same form and under the same terms as the September 2024 Notes, in an aggregate principal amount of $5.0 million (the "January 2025 Notes" and, together with the August 2022 Notes, the June 2024 Notes and the September 2024 Notes, the "Convertible Notes") to Bluescape and Ascend, and (ii) amend and restate the January 2024 Amended and Restated Note Purchase Agreement in the form attached as Annex A to Amendment No. 4 (as amended, the "Amended and Restated Note Purchase Agreement"). The Amended and Restated Note Purchase Agreement also extended the date to which we were required to comply with a financial covenant to maintain a cash balance of at least $7.5 million from December 31, 2024 to March 31, 2025 (the "Minimum Cash Covenant"). Concurrently with the execution of Amendment No. 4, we entered into a restructuring support agreement (the "2025 Restructuring Support Agreement"), and other related agreements, as defined and discussed below.

The net proceeds to us for the January 2025 Notes were approximately $4.7 million after deducting issuance costs and fees payable by us.

*Debt Exchange and Related Agreements*

On January 14, 2025, we entered into the 2025 Restructuring Support Agreement with Bluescape and Ascend in connection with certain restructuring and recapitalization transactions with respect to our capital structure (collectively the "Exchange Transaction"), including our Convertible Notes issued pursuant to the Amended and Restated Note Purchase Agreement.

Pursuant to the 2025 Restructuring Support Agreement, the parties agreed to implement the Exchange Transaction as either an:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Out-of-Court Restructuring: Subject to the satisfaction of customary conditions, including approval by our stockholders, a recapitalization through, among other things:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)pursuant to an Exchange Agreement dated January 14, 2025 among Ascend, Bluescape and us (the "Exchange Agreement"), the issuance of an aggregate of 13,586,524 shares of our Common Stock to Ascend and Bluescape upon exchange of all of the outstanding Convertible Notes (the "Exchange");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)pursuant to a Securities Subscription Agreement dated January 14, 2025 among Ascend, Bluescape and us (the "January 2025 Subscription Agreement"), the issuance and sale by us of an aggregate of $5.0 million of Common Stock to Ascend and Bluescape at a price per share equal to the lesser of (a) $6.716 per share and (b) the volume weighted average price for the Common Stock on the five consecutive trading days immediately following the date of the Exchange (the "Subscription Price");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)pursuant to the January 2025 Subscription Agreement, the issuance by us to Ascend and Bluescape of warrants with a one-year term (the "Restructuring Warrants") to purchase an aggregate number of shares of Common Stock represented by up to $20.0 million divided by the Subscription Price, at a price per share equal to the Subscription Price; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)pursuant to a Fourth Amended and Restated Investor and Registration Rights Agreement dated January 14, 2025 among Ascend, Bluescape and us (the "IRRA"), the right of each of Ascend and Bluescape to designate two directors to serve on our Board of Directors ("Board") following the consummation of the Exchange Transaction for so long as such party beneficially owns 25% of our Common Stock and one director to serve on our Board for so long as such party beneficially owns 10% of our Common Stock (clauses (i) through (iv), together, the "2025 Out-of-Court Restructuring"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•In-Court Restructuring: To the extent that the terms of or the conditions precedent to the 2025 Out-of-Court Restructuring could not be timely satisfied or waived, we would file voluntary pre-packaged cases under chapter 11 of title 11 of the United States Code in a United States Bankruptcy Court (the "Bankruptcy Court") pursuant to a pre-packaged plan of reorganization (the "Pre-Packaged Chapter 11 Plan") pursuant to which, among other things, all of our existing equity interests would be extinguished, with Ascend and Bluescape each owning their respective pro rata share of 100% of the new equity interests in the Company upon the effective date of the Pre-Packaged Chapter 11 Plan (the "In-Court Restructuring"). The 2025 Restructuring Support Agreement further provided that Ascend and Bluescape would provide a $10.0 million debtor-in-possession financing facility pursuant to a debtor-in-possession credit agreement to be agreed upon by the parties and, as necessary, approved by the Bankruptcy Court.

On March 4, 2025, at a special meeting of stockholders, our stockholders voted in favor of the 2025 Out-of-Court Restructuring, and on March 5, 2025 the Exchange was completed and resulted in 13,586,524 shares of the Company's Common Stock issued to Bluescape and Ascend, the termination of the Amended and Restated Note Purchase Agreement and the extinguishment of all indebtedness owed by the Company under the Amended and Restated Note Purchase Agreement.

On March 13, 2025, pursuant to the January 2025 Subscription Agreement, we issued and sold an aggregate of 1,408,173 shares of Common Stock to Bluescape and Ascend, at a Subscription Price of $3.5507 per share for aggregate net proceeds of $4.9 million (the "March 2025 Subscription"). Also pursuant to the January 2025 Subscription Agreement, we issued Restructuring Warrants to purchase up to an aggregate of 5,632,692 shares of Common Stock to Bluescape and Ascend. The Restructuring Warrants are immediately exercisable and expire on March 13, 2026, and have an exercise price per share equal to the Subscription Price.

*May 2025 Equity Offering*

On May 12, 2025 and May 13, 2025, we entered into subscription agreements to issue and sell an aggregate of 1,984,709 shares of our Common Stock at a price of $3.55 per share (collectively, the "May 2025 Subscription"). In connection with the May 2025 Subscription, we also issued 37,042 shares of our Common Stock as an advisory fee. The May 2025 Subscription closed on May 15, 2025 and resulted in aggregate net proceeds to us of approximately $6.4 million after deducting fees and other offering expenses payable by us (inclusive of costs that remained payable by the Company as of June 30, 2025).

*August 2025 Equity Offering*

On August 21, 2025, we entered into an underwriting agreement to issue and sell an aggregate of 2,374,481 shares of our Common Stock at a price of $3.50 per share (the "August 2025 Equity Offering"). The August 2025 Offering closed on August 25, 2025, and resulted in aggregate proceeds of approximately $8.31 million before deducting underwriting discounts and commissions, and other offering expenses payable by us.

------

*Financing Transactions — Liquidity Considerations and Going Concern*

Although the financing transactions described above provided an aggregate of approximately $35.3 million of proceeds to us, prior to recognition of issuance costs and transaction fees, and we continue to operate under a business plan that includes reductions in certain spending, we will need additional financing in order to continue as a going concern for a period of at least one year after the date this Annual Report is issued. The receipt of potential funding cannot be considered probable at this time because these plans are not entirely within management's control as of the date of this Annual Report. Therefore, there exists substantial doubt regarding our ability to continue as a going concern. Even if additional financing is successfully consummated, available liquidity may still not be sufficient to eliminate the aforementioned substantial doubt regarding our ability to continue as a going concern. Refer to the "Going Concern" discussion within Note 1-*Description of Company and Summary of Significant Accounting Policies* of Item 8 of this Annual Report and "Liquidity and Capital Resources" below for more information.

*Export-Import Bank of the United States ("EXIM") Letter of Interest and Meeting*

In September 2024, we received a non-binding Letter of Interest ("LOI") from EXIM. The LOI outlines the potential for the creation of a debt facility of up to $285 million, which would be utilized for commercial-scale development and construction of 5E's Boron Americas Complex. The potential debt funding package would carry a repayment tenor of up to 15 years under EXIM's Make More in America Initiative, a part of a whole-of-government effort to strengthen America's supply chains, support American jobs and boost America's ability to compete with countries like China, especially in sectors critical to national security. We believe the LOI demonstrates a growing awareness and commitment by the U.S. government to securing an integrated boron supply chain.

In late January 2025, our executive management held meetings with representatives of EXIM in Washington, D.C., through which we gained deeper insights into the funding process requirements and expected timetables for EXIM's loan programs, and provided EXIM with additional education on our Project.

We target submitting a formal application to EXIM during the second half of calendar year 2025, at which point we expect EXIM would begin the necessary due diligence to determine if a final commitment may be issued. A final commitment, if any, must comply with EXIM's policies and eligibility requirements, and will depend on meeting EXIM's underwriting criteria, authorization process, finalization and satisfaction of terms and conditions. The LOI does not represent a funding commitment nor an indication of financing or project viability and there is no guarantee that we will secure the EXIM funding commitment.

*Reverse Stock Split*

On February 14, 2025, following approval by our stockholders at our 2024 annual meeting of our stockholders (the "Annual Meeting"), we effected a 1-for-23 reverse stock split (the "Reverse Stock Split") of our Common Stock.

The Reverse Stock Split did not affect the number of authorized shares of Common Stock or the par value of each share of Common Stock. The number of CHESS Depositary Interests ("CDIs") in respect of the Company's shares of Common Stock outstanding immediately prior to the effectiveness of the Reverse Stock Split was proportionately reduced by the final split ratio, subject to rounding. The 1:10 share-to-CDI ratio was not affected by the Reverse Stock Split. Our Common Stock began trading on a post-split adjusted basis on February 18, 2025. On March 4, 2025, we were notified by the Nasdaq Listing Qualifications staff that the closing bid price of our Common Stock had been at $1.00 per share or greater for 10 consecutive business days, from February 18, 2025 to March 3, 2025, and accordingly, that we had regained compliance with Nasdaq Listing Rule 5450(a)(1) and this matter is now closed. If our Common Stock again closes below the $1.00 per share minimum bid price required by Nasdaq for 30 consecutive business days, we would again receive another notice of non-compliance with Nasdaq's listing standards and face the risk of delisting.

All references to the number of shares and per share amounts of our Common Stock included in this Annual Report have been retroactively adjusted to give effect to the Reverse Stock Split for all periods presented.

***Director Changes***

Effective December 31, 2024, David J. Salisbury, Chairman and Director, and Keith Jennings, Director, resigned from the Board, and the Board's size was reduced from six to four. On January 21, 2025, Paul Weibel, our Chief Executive Officer, was elected to the Board at the Annual Meeting, and succeeded Jimmy Lim, who was not re-nominated for election at the Annual Meeting. On March 5, 2025, upon the effectiveness of the Exchange, Mr. Weibel resigned from the Board and was succeeded by Curtis L. Hebert, Jr.

## Results of Operations
Effective April 1, 2024, we placed our SSF into operation, and accordingly all direct operating costs associated with the SSF, including raw materials, labor and maintenance, have been separately classified as Small-scale operating costs within our statements of operations after such date. Prior to April 1, 2024, these direct costs have not been reclassified and remain either as Project expenses or General and administrative costs, as appropriate. As a result of this updated presentation, certain reclassifications have been made to prior years' reported amounts in order to conform to the current year presentation, but these reclassifications did not impact our previously reported net income (loss).

The following table summarizes our results of operations for the periods presented.

***Comparison of the years ended June 30, 2025 and 2024***

*Project expenses*

Project expenses include drilling, plug and abandonment, site preparation, engineering (excluding amounts eligible to be capitalized), consumables, testing and sampling, hydrology, permits, surveys, and other expenses associated with further progressing our Project. Prior to April 1, 2024, Project expenses also included non-labor related costs incurred to prepare for the operation of the SSF, as these costs were incurred prior to the SSF being placed into operation. For the year ended June 30, 2025, Project expenses decreased $1.3 million, or 21%, versus the comparable period in the prior year. The decrease was primarily the result of decreases in: (i) Environmental Protection Agency and other environmental compliance costs, including permit activity ($1.0 million), (ii) testing and analysis costs, primarily for environmental compliance ($0.5 million), (iii) insurance costs ($0.2 million), and (iv) plugging and abandonment ($0.1 million). These decreases were offset to a lesser extent by increases in: (i) an increase in site related costs due to increased activity at the Project ($0.3 million), and (ii) increased wellfield development activity primarily related to the installation of additional observation monitoring wells that were required for environmental compliance ($0.2 million).

*Small-scale facility operating costs*

Small-scale facility operating costs consist of raw materials, salaries and benefits for employees that are directly responsible for the operation of the SSF, and maintenance and upkeep related to the SSF after April 1, 2024. Prior to April 1, 2024, such costs were reported within either Project expenses or General and administrative expenses as the SSF had not yet been placed into operation. Accordingly, for fiscal year 2025, there are four quarters of Small-scale facility operating costs recognized, as compared to only one quarter in the prior year. For the year ended June 30, 2025, Small-scale facility operating costs increased $2.9 million, or 201%, versus the comparable period in the prior year. The increase was primarily the result of: (i) salaries and benefits for our employees directly

------

responsible for operating the SSF ($2.0 million), which represents the increase in operating time of the SSF in the current year, offset by the cost savings associated with the Reduction in Force, (ii) raw materials necessary to operate the SSF and produce boric acid and byproducts ($0.6 million), with such increase being consistent with the increase in operating time for the SSF in the current year and increased throughput as our process was optimized, and (iii) maintenance, upkeep and other costs incurred for the operation of the SSF ($0.3 million), consistent with the increase in operating time for the SSF in the current year.

*General and administrative expenses*

General and administrative expenses include professional fees, costs associated with marketing, on-going SEC and public company costs, public relations, rent, salaries for administrative personnel within the Company, share-based compensation and other expenses. Prior to April 1, 2024, all salaries and benefits for the entire organization were reported in general and administrative expenses. After April 1, 2024, the date which we began operation of the SSF, salaries and benefits for employees that are directly responsible for the operation of the SSF are reported in Small-scale facility operating costs. Accordingly, for fiscal year 2025, no salaries and benefits for employees who operate the SSF are included in General and administrative expenses, as compared to three quarters in the prior year. For the year ended June 30, 2025, general and administrative expenses decreased $8.4 million, or 37%, versus the comparable period in the prior fiscal year. The decrease was primarily due to decreases in: (i) base compensation and employee benefits, resulting from the combined impact of (a) salaries and benefits for personnel responsible for the operation of the SSF now reported as Small-scale facility operating costs, and (b) a reduction in head count across the organization, including the Reduction in Force (for a combined impact of $2.9 million), (ii) incentive compensation related costs, inclusive of share-based compensation expense ($2.8 million), which is amplified by significant share-based compensation expense in the prior year due to the acceleration of expense associated with severance agreements with former employees and a prior year cash-based retention program for certain key employees in connection with a debt restructuring transaction (iii) other employee related severance and relocation costs ($1.0 million), (iv) professional fees, primarily as a result of incurring incremental legal fees in the prior year leading up to the January 2024 restructuring transaction ($0.7 million), (v) miscellaneous and travel costs resulting from cost cutting measures across the organization ($0.4 million), (vi) insurance related costs ($0.3 million), (vii) marketing related costs ($0.2 million) and (vii) information technology related costs ($0.1 million).

*Research and development*

Research and development expense includes costs incurred under research agreements with Georgetown University and Boston College that aim to enhance the performance of permanent magnets through increased use of boron. Both engagements were completed during the second fiscal quarter of 2024. Therefore, we incurred no research and development costs in the year ended June 30, 2025, compared to $45 thousand in research and development costs incurred in the prior fiscal year.

*Depreciation and amortization expense*

Depreciation and amortization relate to use of our SSF, injection and recovery wells, owned or leased vehicles, buildings and equipment and the accretion of our asset retirement obligations. For the year ended June 30, 2025, depreciation and amortization expense increased $14.8 million, or 286%, versus the comparable period in the prior year. This increase was primarily due to placing the SSF and its related injection and recovery wells, facilities, and equipment into service as of April 1, 2024, corresponding with the commencement of operations.

*Interest income*

Interest income is derived from the investment of our excess cash and cash equivalents in short-term (original maturities of three months or less) investments of highly liquid treasury bills and certificates of deposit. For the year ended June 30, 2025, interest income decreased $149 thousand, or 59%, versus the comparable period in the prior fiscal year. Such decreases correspond to decreases in our average cash and cash equivalent balances between periods.

*Other income*

Other income is derived from the sale of scrap and other materials, the third-party use of our hydrology wells, and other non-operating income. For the year ended June 30, 2025, other income was consistent with the prior fiscal year.

------

*Gain (Loss) on extinguishment of debt*

The gain on extinguishment of debt incurred for the year ended June 30, 2025 resulted from the Exchange Transaction and the related extinguishment of all indebtedness owed by the Company under the Amended and Restated Note Purchase Agreement. As discussed within Note 7–*Debt* to the financial statements included in Item 8 of this Annual Report, the Exchange Transaction was accounted for as a troubled debt restructuring. As a result, we derecognized the remaining principal, accrued interest and unamortized discount and debt issuance costs associated with the Convertible Notes of $82.4 million, and recognized the fair value of various equity interests issued to the former noteholders, less $5.0 million of proceeds received, at their fair value of $65.1 million. The difference in value between the Convertible Notes and the net fair value of equity interests issued resulted in a gain on extinguishment of debt of $17.3 million.

The loss on extinguishment of debt incurred for the year ended June 30, 2024 resulted from the modification of the terms of our Convertible Notes contained in the January 2024 Amended and Restated Note Purchase Agreement executed January 18, 2024. The modified terms of the Convertible Notes were evaluated and determined to be representative of an in-substance extinguishment of the Convertible Notes and establishment of new debt, for accounting purposes, primarily due to the significance of the changes to the terms of the conversion features. As a result, we derecognized the remaining principal, accrued interest and unamortized discount and debt issuance costs associated with the prior debt with an aggregate value of $44.2 million, and recognized the modified debt at its fair value of $65.2 million upon execution of the Amended and Restated Note Purchase Agreement. The difference in value between the prior debt and the modified debt resulted in a loss on extinguishment of debt of $21.0 million.

*Derivative gain*

Derivative gain (loss) results from changes in the fair value of the embedded conversion features relating to degressive issuance provisions originally contained in the May 2024 Amended and Restated Note Purchase Agreement, and subsequently incorporated into and continued under the September 2024 Amended and Restated Note Purchase Agreement. As a result, these conversion features were deemed to be embedded derivatives requiring bifurcation and separate accounting as stand-alone derivative instruments (the "June 2024 Convertible Note Derivative" and "September 2024 Convertible Note Derivative"). On December 31, 2024, upon the expiration of the degressive issuance conversion feature associated with the June 2024 Notes and September 2024 Notes, the June 2024 Convertible Note Derivative and September 2024 Convertible Note Derivative expired and the remaining aggregate fair value of such derivatives of $3.6 million was transferred to additional paid-in capital. Refer to Note 7–*Debt* and Note 8–*Convertible Note Derivatives* to the financial statements included in Item 8 of this Annual Report for additional details.

The unrealized derivative gain of $1.4 million during the year ended June 30, 2025, was primarily due to a decrease in our stock price during the period, which resulted in a gain on the June 2024 Convertible Note Derivative. Our stock prices on June 28, 2024 (the last trading day prior to the end of our prior fiscal year) and December 31, 2024 (the date the June 2024 Convertible Note Derivative expired) were $27.83 and $14.72, respectively. The observed decline in our stock price resulted in a decline in the value of the embedded conversion feature liability and a resulting derivative gain of $2.2 million. This derivative gain was offset, by a loss with respect to the September 2024 Convertible Note Derivative during the same period, which was primarily due to an increase in our stock price from $11.50 on September 16, 2024 (the issuance date of the September 2024 Notes) to $14.72 on December 31, 2024 (the date the September 2024 Convertible Note Derivative expired), resulting in an increase in the value of the embedded conversion feature liability during such period and a resulting derivative loss of $0.8 million, for a net derivative gain of approximately $1.4 million for the year ended June 30, 2025.

The unrealized derivative gain of $0.7 million during the year ended June 30, 2024, was primarily due to a decrease in our stock price during the period, which resulted in a gain on the June 2024 Convertible Note Derivative. Our stock prices on June 11, 2024 (the issuance date of the June 2024 Notes) and June 28, 2024 (the last trading day prior to the end of our prior fiscal year) were $33.12 and $27.83, respectively. The observed decline in our stock price resulted in a decline in the value of the embedded conversion feature liability and a resulting derivative gain of $0.7 million.

*Interest expense*

Interest expense primarily related to interest expense incurred on the Convertible Notes and was net of amounts capitalized to construction-in-progress. Prior to the January 2024 Amended and Restated Note Purchase Agreement, the August 2022 Notes accrued interest at a rate of 6% when interest was paid-in-kind through the issuance of additional notes. Subsequent to the January 2024 Amended and Restated Note Purchase Agreement, the August 2022 Notes accrued interest at a rate of 10% when interest was paid-in-kind through the issuance of additional notes, with such rate also applying to the June 2024 Notes, September 2024 Notes and January 2025 Notes. We also recognized interest expense for the amortization of debt issuance costs and the amortization of debt discounts on the Convertible Notes. As part of the modification of the terms of our debt associated with the January 2024 Amended and Restated

------

Note Purchase Agreement, the modified debt was recognized at fair value on our balance sheet which eliminated the prior debt discount and prior debt issuance costs that were amortized to interest expense. In connection with the Exchange Transaction on March 5, 2025, all indebtedness owed by the Company under the Amended and Restated Note Purchase Agreement was extinguished and the recognition of interest expense ceased.

For the year ended June 30, 2025, interest expense increased $0.3 million, or 4%, versus the comparable period in the prior fiscal year. This increase was primarily the result of (i) capitalizing less interest expense to construction-in-progress between periods (which results in an increase in the amount of interest expense recognized) as a result of the SSF being placed into service on April 1, 2024 and therefore no longer eligible for interest capitalization (an impact of $2.3 million increase in interest expense), and (ii) the combined effect of interest accruing (a) at 10% under the terms of our January 2024 Amended and Restated Note Purchase Agreement compared to 6% under our prior agreement in the prior period, (b) on a $11.0 million aggregate increase in the principal balance of Convertible Notes resulting from the issuance of the September 2024 Notes and January 2025 Notes, (c) on $3.4 million and $4.0 million of interest that was paid-in-kind during August of 2024 and February 2025, respectively, and (d) for a shorter period of time in current year resulting from the Exchange Transaction (for a combined impact of $0.4 million increase in interest expense). These increases were partially offset by the combined effects of a reduction in (i) the amount of debt discount amortization from the combined impact of (a) the write-off of the remaining unamortized debt discount (established August 26, 2022) and corresponding elimination of the amortization of such amount in connection with the accounting for the January 2024 Amended and Restated Note Purchase Agreement, and (b) a shorter period of amortization in the current year resulting from the Exchange Transaction (for a combined impact of $2.2 million decrease in interest expense), and (ii) the amount of debt issuance cost amortization from the combined impact of (a) the write-off of the remaining unamortized debt issuance costs (established August 26, 2022) and corresponding elimination of the amortization of such amount in connection with the accounting for the January 2024 Amended and Restated Note Purchase Agreement, (b) a shorter period of amortization in the current year resulting from the Exchange Transaction, and (c) an increase of approximately $0.8 million in debt issuance costs between periods as a result of costs incurred for the issuance of the September 2024 Notes and January 2025 Notes (for a combined impact of $0.2 million decrease in interest expense).

*Other expense*

Other expense relates to losses on foreign currency transactions and certain non-income related taxes and penalties. For the year ended June 30, 2025, other expense decreased $7 thousand, or 78%, versus the prior year. The decrease primarily relates to reduced foreign currency transaction losses compared to the prior year.

*Income tax expense* 

Income tax expense relates to federal, state and foreign taxes levied on our income, subject to the applicable tax codes and regulations. For the year ended June 30, 2025, we incurred income tax expense of approximately $179 thousand. Such income tax expense was primarily the result of cancellation of debt income recognized as a result of the Exchange which was not eligible to be fully offset with accumulated net operating losses subject to limitation or exclusion from income under the applicable tax code, which resulted in federal income tax expense. We did not have any income tax expense or benefit for the year ended June 30, 2024. We have recorded a full valuation allowance against our net deferred tax asset.

## Liquidity and Capital Resources
***Overview***

As of June 30, 2025, we had cash and cash equivalents of $3.8 million and a working capital deficit of $1.8 million compared to $4.9 million of cash and cash equivalents and a working capital deficit of $2.9 million as of June 30, 2024. We maintain the majority of our cash and cash equivalents in accounts with major U.S. and multi-national financial institutions, and our deposits at certain of these institutions may exceed insured limits. Market conditions can impact the viability of these institutions.

Our predominant source of cash has been generated through equity financing from issuances of our common stock and equity-linked securities, including our Convertible Notes. Since inception, we have not generated revenues, and as such, have relied on equity financing and equity-linked instruments to fund our operating and investing activities.

In August 2022, we executed a $60 million private placement of senior secured convertible notes (the "August 2022 Notes") to complete construction and commissioning of our SSF, fund operation of our SSF, and general corporate purposes. During fiscal year 2024, we completed an out-of-court restructuring, two closings of a private placement of our Common Stock, and issued the June 2024 Notes, each to strengthen our balance sheet and to help fund mining and SSF operations. Refer to Note 1–*Description of* 

------

*Company and Summary of Significant Accounting Policies,* Note 7–*Debt* and Note 10–*Equity* to the financial statements included in Item 8 of this Annual Report for additional details of each of these financing activities.

During fiscal year 2025, we completed the August 2024 Equity Issuance, issued the September 2024 Notes, issued the January 2025 Notes, completed the 2025 Out-of-Court restructuring, completed the March 2025 Subscription and completed the May 2025 Subscription, each of these transactions aimed at strengthening our balance sheet, to help fund mining and SSF operations and to further progress our FEL-2 engineering program for the proposed commercial scale-facility. As a result of the Exchange Transaction in March of 2025, all outstanding indebtedness pursuant to the Amended and Restated Convertible Note Agreement was extinguished in exchange for equity interests in the Company, and the Minimum Cash Covenant was eliminated. Refer to the discussion above under the caption *Fiscal Year 2025 Highlights and Future Considerations-Financing Highlights* within this section of the Annual Report for additional details of each of these financing transactions.

A summary of our cash flows for the years ended June 30 follows.

*Cash Flows Used For Operating Activities*

Net cash used in operating activities for each of the above periods was primarily the result of general and administrative costs (exclusive of share based compensation), costs incurred in furthering the Project, operating costs of the SSF, the funding of reclamation bond accounts, and transaction costs incurred related to the Exchange Transaction that were not directly related to the issuance of the related equity interests issued to our former noteholders. During the year ended June 30, 2025, we used $23.6 million of cash for operating activities, a decrease of approximately $3.2 million or 12% compared to the comparable period in the prior fiscal year. The decrease in cash used in operations during the current period primarily results from the decrease in General and administrative expenses, net of non-cash share-based compensation expense, offset by the incurrence of Small-scale facility operating costs (refer to the discussion of year-over-year changes in General and administrative expenses and Small-scale facility operating costs within *Results of Operations* above for additional details).

*Cash Flows Used For Investing Activities*

Our cash flows used for investing activities primarily relate to equipment purchases, the construction and commissioning of our SSF, stage 2 of our front-end loading ("FEL-2") engineering and related vendor testing related to our commercial-scale facility. During the year ended June 30, 2025, we used $2.0 million of cash for investing activities, a decrease of approximately $5.2 million, or 73%, compared to the comparable period in the prior fiscal year. Net cash used in investing activities during the year ended June 30, 2025 related to engineering services for FEL-2 engineering and related vendor testing for our commercial-scale facility. Net cash used in investing activities during the year ended June 30, 2024 primarily related to final construction and commissioning of our SSF.

*Cash Flows From Financing Activities*

Our cash flows from financing activities primarily relate to equity and equity-linked financing transactions to fund our business and operations. Cash flows provided by financing activities for the year ended June 30, 2025 were the result of (i) approximately $3.0 million of net proceeds received from the August 2024 Equity Offering, (ii) approximately $5.5 million of net proceeds received from the issuance of September 2024 Notes, (iii) approximately $4.7 million of net proceeds received from the issuance of January 2025 Notes, (iv) approximately $4.9 million of net proceeds received from the March 2025 Subscription, after recognition of the related costs and fees related directly to the issuance of the related equity instruments, (v) approximately $6.6 million of proceeds received from the May 2025 Equity Offering (exclusive of amounts that remain payable as of June 30, 2025), and (vi) approximately $0.2 million of taxes paid upon the vesting and release of shares for equity awards.

Cash flows provided by financing activities for the year ended 2024 were the result of (ii) $15.8 million of net proceeds received from two closings of a private placement of our Common Stock in January of 2024, (ii) $2.6 million of cash used to pay legal and

------

accounting fees associated with the January 2024 Amended and Restated Note Purchase Agreement, and (iii) approximately $5.5 million of net proceeds received from the issuance of June 2024 Notes.

## Material Cash Requirements
Our material short-term cash requirements include general and administrative expenses including recurring payroll and benefit obligations for our employees, costs necessary to further the engineering of our proposed commercial-scale facility, professional fees, operating costs for the SSF, Project related costs, payments under certain lease agreements and working capital needs. Our long-term material cash requirements from currently known obligations include future obligations to reclaim, remediate, or otherwise restore properties to a condition that existed prior to our operations, and $3.5 million of purchase order commitments for drilling and other services related to our wellfield development program, raw materials for the operation of the SSF, engineering services and vendor tested related to the design of our proposed commercial-scale facility, environmental testing and other corporate services. Refer to the "Construction in Progress," "Asset Retirement Obligations," "Accounts Payable and Accrued Liabilities," and "Commitments and Contingencies" footnotes in the financial statements included in Item 8 of this Annual Report for more information on certain of these expenditures and obligations.

***Future Capital Requirements and Going Concern***

Over the next 12 months we have the following plans that will require additional capital:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Operate the SSF to provide the necessary data for our commercial-scale facility, progress our customer qualification program and validate our wellfield design and operational plans;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Progress FEL-3, and the related detailed engineering and vendor testing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Optimize well-field design and operating plan in an effort to reduce future mining capital and operational expenditures through various drilling techniques such as directional, horizontal, and radial drilling;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Pursue and optimize infrastructure capital expenditures for our larger-scale facility which could include expansion of non-potable water resources, upgrading shore power, connection to a natural gas network, preparing certain lands for the construction of the proposed commercial-scale facility, and constructing new access roads into and out of the location for our proposed commercial-scale facility; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Further define our advanced boron materials strategy with consideration to engineering and repurposing our SSF once sufficient data has been obtained for flow sheet optimization and the production of product for customer qualification.

Although the August 2024 Equity Offering, issuance of the September 2024 Notes, issuance of the January 2025 Notes, proceeds received in the March 2025 Subscription, May 2025 Subscription and August 2025 Equity Offering improved our cash position, and we continue to operate under a business plan that includes reductions in certain spending, we will need additional financing within the next twelve months. Absent additional financing, we may no longer be able to meet our ongoing obligations, continue operations or achieve the milestones outlined above.

We intend to explore different potential financing strategies to help support the growth of our business and execution of our business plan, including equity or debt financing, government funding or grants, private capital, royalty agreements or customer prepayments, the exercise of a significant portion of the warrants outstanding to acquire our Common Stock, or other strategic alliances with third parties. However, there is no assurance that we will be able to secure additional financing on adequate terms, in a timely manner, or at all.

The receipt of any potential funding cannot be considered probable at this time because these plans are not entirely within our control as of the date of this Annual Report. Therefore, there exists substantial doubt regarding our ability to continue as a going concern for a period of one year after the date of this Annual Report. Even if additional financing is successfully consummated, available liquidity may still not be sufficient to eliminate the aforementioned substantial doubt regarding our ability to continue as a going concern. If the Company is unable to raise additional capital or generate cash flows necessary to fund our operations, we will need to curtail planned activities, discontinue certain operations, or sell certain assets, which could materially and adversely affect our business, financial condition, results of operations, and prospects. Refer to the "Going Concern" discussion within Note 1–*Description of Company and Summary of Significant Accounting Policies* included in Item 8 of this Annual Report for more information.

***2024 Equity Distribution Agreement***

On March 28, 2024, we entered into an equity distribution agreement (the "Equity Distribution Agreement") with Canaccord Genuity LLC and D.A. Davidson & Co. (the "Agents") pursuant to which we may offer and sell up to $15.0 million of shares of our Common Stock from time to time through the Agents, acting as our sales agents, or directly to one or more of the Agents, acting as principal. On August 14, 2025, the Equity Distribution Agreement was terminated pursuant to the terms therein. The Company is not subject to any termination penalties related to the termination of the Equity Distribution Agreement. We did not sell any shares of our common stock under the Equity Distribution Agreement.

## Critical Accounting Policies and Estimates
***Use of Estimates*** 

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates, assumptions and allocations that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of expenses during the reporting periods. Actual results could differ materially from those estimates. Our significant estimates and assumptions may include the estimated useful lives and valuation of properties, plant and equipment, mineral rights and properties, deferred tax assets, reclamation liabilities and share-based compensation. See Note 1–*Description of Company and Summary of Significant Accounting Policies* to our consolidated financial statements included in Item 8 of this Annual Report for a full description of the critical accounting policies and estimates below, as well as other accounting policies and estimates we make. Below are the most significant policies we apply in preparing our financial statements, which also describe the most significant estimates and assumptions we make in applying these policies.

***Asset Retirement Obligations***

Our mining, exploration and development activities are subject to various laws and regulations, including legal and contractual obligations to reclaim, remediate, or otherwise restore properties at the time the property is removed from service. We estimate these costs based upon internally generated information and information obtained from outside sources. These estimates are then inflated and discounted based on when the expenditures are expected to be incurred and recorded at fair value as an asset and corresponding liability on our consolidated balance sheet. Because these costs typically extend many years into the future, estimation is difficult and requires judgments that are subject to revisions based upon numerous factors, including inflation, changing technology and the political and regulatory environment in which we operate. Changes in cost estimates, discount rates, timing of abandonment activities or inflation, among others, could have a significant impact on our future results of operations or liquidity. We review our assumptions and estimates of future development and abandonment costs annually, or more frequently if circumstances change. See Note 5-*Asset Retirement Obligations* to our consolidated financial statements included in Item 8 of this Annual Report.

***Derivative Financial Instruments***

We record derivative instruments on our consolidated balance sheet at fair value as either an asset or a liability with changes in fair value recognized currently in earnings. During the years ended June 30, 2025 and 2024, we recognized two separate derivative instruments, each related to beneficial conversion features associated with our Convertible Notes. The valuation methodology used as the basis of determining the amount allocated to the derivative instruments and the related derivative gains was a with-and-without methodology utilizing a binomial lattice model (Level 3). This model required the use of assumptions that were subjective, and had different assumptions been used, the resulting derivative gains and amount reflected as a discount to the respective Convertible Notes could have been materially different. See Note 8–*Convertible Notes Derivatives* to our consolidated financial statements included in Item 8 of this Annual Report.

***Properties, Plant and Equipment***

We record properties, plant and equipment at historical cost. Depreciation and amortization expense is provided in amounts sufficient to match the cost of depreciable assets to operations over their estimated service lives or productive value, whichever is shorter. There is inherent judgment applied in determining an assets useful life, particularly related to the useful life we have assigned to the SSF and its related injection and recovery wells since we do not have a historical basis of comparison for similar assets, and there are limited comparable projects to utilize in benchmarking. If different useful lives had been used, the resulting depreciation expense recognized may be materially different. We review our assumptions and estimates for the assigned useful lives annually, or more frequently if circumstances change. Expenditures for improvements that significantly extend the useful life of an asset are

------

capitalized. Expenditures for maintenance and repairs are charged to expense when incurred. See Note 4–*Properties, Plant and Equipment, Net* to our consolidated financial statements included in Item 8 of this Annual Report.

***Share-Based Compensation*** 

We apply a fair value-based method of accounting for stock-based compensation, which requires recognition in the financial statements of the cost of services received in exchange for equity awards. Compensation expense is based on the fair value on the grant or modification date and is recognized in our financial statements over the vesting period with a corresponding increase in additional paid-in capital. We utilize the Black-Scholes option-pricing model to measure the fair value of stock options and our stock price on the date of grant for restricted stock units and performance based restricted stock units. See Note 11–*Share-Based Compensation* to our consolidated financial statements in Item 8 of this Annual Report for a full discussion of our stock-based compensation.

## *New Accounting Pronouncements and Requirements* 
See Note 1–*Description of Company and Summary of Significant Accounting Policies* and specifically the discussion under the heading *Recently Issued and Adopted Accounting Pronouncements* to our consolidated financial statements included in Item 8 of this Annual Report for a discussion of new accounting requirements and related status of our adoption.

**Report of Independent Registered Public Accounting Firm** 

To the Board of Directors and Stockholders of 5E Advanced Materials, Inc.

***Opinion on the Financial Statements***

We have audited the accompanying consolidated balance sheets of 5E Advanced Materials, Inc. and its subsidiaries (the "Company") as of June 30, 2025 and 2024, and the related consolidated statements of operations, of changes in stockholders' equity and of cash flows for the years then ended, including the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of June 30, 2025 and 2024, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

***Substantial Doubt About the Company's Ability to Continue as a Going Concern***

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company currently generates no revenue from operations and has incurred recurring losses from operations and will need to secure additional financing in the next twelve months to maintain its operations, which raises substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

***Basis for Opinion***

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control

over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

**5E ADVANCED MATERIALS, INC.** 

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

1. Description of Company and Summary of Significant Accounting Policies

***Nature of Business*** 

5E Advanced Materials, Inc. ("5E," or the "Company") is a development stage company focused on becoming a vertically integrated global leader and supplier of refined borates and advanced boron derivative materials whose mission is to enable decarbonization, increase food security, and ensure domestic supply of critical materials. The Company's business strategy and objectives are to develop capabilities ranging from upstream extraction and product sales of borates, calcium-based co-products, potentially other byproducts such as lithium carbonate, to downstream boron advanced material processing and development. The Company holds 100% of the rights through ownership and lode claims filed with the United States Bureau of Land Management in the 5E Boron Americas (Fort Cady) Complex (the "Project") located in southern California through its wholly owned subsidiary 5E Boron Americas LLC (formerly Fort Cady (California) Corporation ("5EBA")). The Project is underpinned by a boron reserve and lithium resource, with the boron being contained in a conventional boron mineral known as colemanite. In 2022, the Company's facility was designated as Critical Infrastructure by the U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency. The Company is currently operating its small-scale facility (the "SSF") at the Project, which provides data and information necessary for the Company to ultimately establish a commercial-scale facility at the Project.

***Reorganization Scheme***

5E acquired all of the issued and outstanding shares of American Pacific Borates Limited ("ABR"), the Company's Australian predecessor and wholly owned subsidiary, pursuant to a Scheme of Arrangement ("Scheme") under Australian law, which was approved by ABR's shareholders on December 2, 2021, and the Supreme Court of Western Australia on February 24, 2022. As part of the Scheme, 5E became the parent company of ABR and changed its place of domicile from Australia to the State of Delaware in the United States, effective on March 8, 2022.

In accordance with the Scheme, all ordinary shares of ABR have been transferred to 5E and pursuant to the Scheme, the Company issued to the shareholders of ABR, either one share of its common stock, par value $0.01 (the "Common Stock") for every ten ordinary shares of ABR or one CHESS Depositary Interest ("CDI") of its common stock for every one ordinary share of ABR, in each case, as held on the Scheme record date. The Company maintains an Australian Stock Exchange ("ASX") listing for its CDIs, with each CDI representing 1/10<sup>th</sup> of a share of Common Stock. Holders of CDIs are able to trade their CDIs on the ASX under the symbol "5EA" and holders of shares of the Company's Common Stock are able to trade their shares on Nasdaq under the symbol "FEAM." All share and per share data presented in the consolidated financial statements is presented on the basis of the Company's Common Stock.

***2024 Out-of-Court Restructuring***

On November 9, 2023, the Company entered into a standstill agreement (the "Standstill Agreement") with Bluescape Special Situations IV ("Bluescape"), Alter Domus (US) LLC (the "Collateral Agent"), Ascend Global Investment Fund SPC for and on behalf of Strategic SP, and Mayfair Ventures Pte Ltd in connection with the Company's then outstanding 4.50% senior secured convertible notes (the "Original Convertible Notes"). Pursuant to the Standstill Agreement, Bluescape and the Collateral Agent agreed to not exercise their respective rights, remedies, powers, privileges, and defenses under a note purchase agreement, dated August 11, 2022 (the "Note Purchase Agreement") with respect to the occurrence of any default or event of default, and all parties to the Standstill Agreement agreed to forbear from instituting or pursuing legal action with respect to the Original Convertible Notes. The Standstill Agreement also temporarily allowed the Company to go below its then enforceable cash covenant of $10 million.

On December 1, 2023, the effectiveness of the Standstill Agreement was extended from December 1, 2023 to December 5, 2023 at which point the Company entered into a restructuring support agreement (the "2023 Restructuring Support Agreement") with Bluescape, the Collateral Agent, and Ascend Global Investment Fund SPC for and on behalf of Strategic SP in connection with certain restructuring transactions with respect to the Company's capital structure, including the Company's Original Convertible Notes. Pursuant to the 2023 Restructuring Support Agreement, the parties agreed to implement the restructuring transactions either as an out-of-court restructuring (the "2024 Out-of-Court Restructuring") or an in-court restructuring under voluntary pre-packaged cases under chapter 11 of title 11 of the United States Code in a United States Bankruptcy Court (the "Bankruptcy Court").

------

On January 12, 2024, the Company held a special meeting of stockholders (the "2024 Special Meeting") where the Company's stockholders approved the 2024 Out-of-Court Restructuring, including (i) an amendment to the Company's certificate of incorporation to increase the number of authorized shares of the Company's Common Stock from 180,000,000 to 360,000,000, (ii) the issuance of up to $35 million of Common Stock at a price of $23.575 per share (the "2024 Securities Offering") to Ascend Global Investment Fund SPC for and on behalf of Strategic SP and Bluescape, if Bluescape decided to exercise its option to participate in the Securities Offering, and (iii) the issuance of additional shares of the Company's Common Stock upon conversion of the Original Convertible Notes in connection with an amendment to the Note Purchase Agreement.

In accordance with the results from the 2024 Special Meeting, during January 2024, the Company issued Common Stock in two separate transactions that resulted in net proceeds to the Company of approximately $15.8 million (as further described in Note 10–*Equity*) and entered into an amended and restated note purchase agreement (the "January 2024 Amended and Restated Note Purchase Agreement," as further described in Note 7–*Debt*), which completed the 2024 Out-of-Court Restructuring.

***Reverse Stock Split***

On January 21, 2025, at an annual meeting of stockholders, the Company's stockholders approved amendments to the Company's Amended and Restated Certificate of Incorporation to effect a reverse stock split of the Company's Common Stock at a ratio ranging from any whole number between 1-for-10 and 1-for-25, with the exact ratio within such range to be determined by the Company's Board of Directors (the "Board") in its discretion. On February 3, 2025, the Board approved a 1-for-23 reverse stock split, which became effective at 5:00 p.m., Eastern Time on February 14, 2025 (the "Effective Time"), upon filing of an amendment to the Amended and Restated Certificate of Incorporation (the "Charter Amendment") with the Secretary of State of the State of Delaware (the "Reverse Stock Split").

As a result of the Reverse Stock Split, at the Effective Time, every 23 shares of the Company's issued and outstanding shares of Common Stock immediately prior to the Effective Time, were automatically converted, without any action on the part of the holder thereof, into one validly issued, fully-paid and non-assessable share of Common Stock, subject to the treatment of fractional shares as described below.

The Charter Amendment did not affect the number of authorized shares of Common Stock or the par value of each share of Common Stock. The number of CDIs in respect of the Company's shares of Common Stock outstanding immediately prior to the effectiveness of the Reverse Stock Split was proportionately reduced by the final split ratio, subject to rounding. The 1:10 share-to-CDI ratio was not affected by the Reverse Stock Split.

No fractional shares of Common Stock or CDIs were issued as a result of the Reverse Stock Split. Holders of Common Stock who otherwise would have been entitled to receive a fractional share of Common Stock in connection with the Reverse Stock Split received a cash payment in lieu thereof.

As a result of the Reverse Stock Split, proportionate adjustments were made to the per share exercise price and the number of shares issuable upon the exercise of all outstanding options and warrants to purchase shares of the Company's Common Stock, and a proportionate adjustment was made to the number of shares issuable upon the vesting of all outstanding Restricted Stock Units and Performance Stock Units.

These notes to the consolidated financial statements and the accompanying consolidated financial statements give retroactive effect to the Reverse Stock Split for all periods presented.

***Debt Exchange and Related Agreements***

On January 14, 2025, the Company entered into a restructuring support agreement (the "2025 Restructuring Support Agreement") with Bluescape, Meridian Investments Corporation ("Meridian") and Ascend Global Investment Fund SPC, for and on behalf of Strategic SP (together with Meridian, "Ascend") in connection with certain restructuring and recapitalization transactions with respect to the Company's capital structure (collectively the "Exchange Transaction"), including the Company's Convertible Notes (as defined in Note 7–*Debt*) issued pursuant to the Amended and Restated Note Purchase Agreement (as defined in Note 7–*Debt*) by and among the Company, Bluescape, Ascend, the guarantors from time to time party thereto and the Collateral Agent.

------

Pursuant to the 2025 Restructuring Support Agreement, the parties agreed to implement the Exchange Transaction either as an:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Out-of-Court Restructuring: Subject to the satisfaction of customary conditions, including approval by the Company's stockholders, a recapitalization through, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)pursuant to an Exchange Agreement dated January 14, 2025 among the Company, Ascend and Bluescape (the "Exchange Agreement"), the issuance of an aggregate of 13,586,524 shares of the Company's Common Stock, to Ascend and Bluescape upon exchange of all of the outstanding Convertible Notes (as defined in Note 7-*Debt*) (the "Exchange");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)pursuant to a Securities Subscription Agreement dated January 14, 2025 among the Company, Ascend and Bluescape (the "January 2025 Subscription Agreement"), the issuance and sale by the Company of an aggregate of $5.0 million of Common Stock to Ascend and Bluescape at a price per share equal to the lesser of (a) $6.716 per share and (b) the volume weighted average price for the Common Stock on the five consecutive trading days immediately following the date of the Exchange (the "Subscription Price");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)pursuant to the January 2025 Subscription Agreement, the issuance by the Company to Ascend and Bluescape of warrants with a one-year term (the "Restructuring Warrants") to purchase an aggregate number of shares of Common Stock represented by up to $20.0 million divided by the Subscription Price, at a price per share equal to the Subscription Price; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)pursuant to a Fourth Amended and Restated Investor and Registration Rights Agreement dated January 14, 2025 among the Company, Ascend and Bluescape (the "IRRA"), the right of each of Ascend and Bluescape to designate two directors to serve on the Company's Board following the consummation of the Exchange Transaction for so long as such party beneficially owns 25% of the Company's Common Stock and one director to serve on the Company's Board for so long as such party beneficially owns 10% of the Company's Common Stock (clauses (i) through (iv), together, the "2025 Out-of-Court Restructuring"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•In-Court Restructuring: To the extent that the terms of or the conditions precedent to the 2025 Out-of-Court Restructuring could not be timely satisfied or waived, the Company would file voluntary pre-packaged cases under chapter 11 of title 11 of the United States Code in the Bankruptcy Court pursuant to a pre-packaged plan of reorganization (the "Pre-Packaged Chapter 11 Plan") pursuant to which, among other things, all existing equity interests of the Company would be extinguished, with Ascend and Bluescape each owning their respective pro rata share of 100% of the new equity interests in the Company upon the effective date of the Pre-Packaged Chapter 11 Plan (the "In-Court Restructuring"). The 2025 Restructuring Support Agreement further provided that Ascend and Bluescape would provide a $10.0 million debtor-in-possession financing facility pursuant to a debtor-in-possession credit agreement to be agreed upon by the parties and, as necessary, approved by the Bankruptcy Court.

On March 4, 2025, at a special meeting of stockholders, the Company's stockholders voted in favor of the 2025 Out-of-Court Restructuring, and on March 5, 2025 the Exchange was completed and resulted in 13,586,524 shares of the Company's Common Stock issued to Bluescape and Ascend, the termination of the Amended and Restated Note Purchase Agreement (as defined in Note 7–*Debt)* and the extinguishment of all indebtedness owed by the Company under the Amended and Restated Note Purchase Agreement (as defined in Note 7–*Debt)*.

On March 13, 2025, pursuant to the January 2025 Subscription Agreement, the Company issued and sold an aggregate of 1,408,173 shares of Common Stock to Bluescape and Ascend, at a Subscription Price of $3.5507 per share for aggregate net proceeds of $4.9 million (the "March 2025 Subscription"). Also pursuant to the January 2025 Subscription Agreement, the Company issued Restructuring Warrants to purchase up to an aggregate of 5,632,692 shares of Common Stock to Bluescape and Ascend. The Restructuring Warrants are immediately exercisable and expire on March 13, 2026, and have an exercise price per share equal to the Subscription Price.

***Going Concern***

Management evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern for one year after the date that these consolidated financial statements are issued. When substantial doubt exists, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company's ability to continue as a going concern. The mitigating effect of management's plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions

------

or events that raise substantial doubt about the Company's ability to continue as a going concern for one year after the date that the consolidated financial statements are issued. In performing this analysis, management concluded there continues to exist substantial doubt regarding the Company's ability to continue as a going concern.

Although the August 2024 Equity Offering (as further described and defined in Note 10–*Equity*) provided net cash proceeds of approximately $3.0 million, the issuance of the September 2024 Notes and January 2025 Notes (each as further described and defined in Note 7–*Debt*) provided aggregate net cash proceeds of approximately $10.2 million, the March 2025 Subscription provided net cash proceeds of approximately $4.9 million, the May 2025 Equity Offering (as further described and defined in Note 10–*Equity* provided net cash proceeds of approximately $6.4 million (inclusive of costs that remained payable by the Company as of June 30, 2025), and the August 2025 Equity Offering (as further described and defined in Note 16–*Subsequent Events* provided proceeds to the Company before costs payable by the Company of approximately $8.3 million, each of which improved the Company's cash position, and while the Company continues to operate under a business plan that includes reductions in certain spending, management anticipates the need for additional financing within the next twelve months to maintain its operations. The receipt of potential funding cannot be considered probable at this time because these plans are not entirely within management's control as of the date of these consolidated financial statements. Therefore, there exists substantial doubt regarding the Company's ability to continue as a going concern. Even if additional financing is successfully consummated, available liquidity may still not be sufficient to eliminate the aforementioned substantial doubt regarding the Company's ability to continue as a going concern. If the Company is unable to raise additional capital or generate cash flows necessary to fund its operations, the Company will need to curtail planned activities, discontinue certain operations, or sell certain assets, which could materially and adversely affect its business, financial condition, results of operations, and prospects.

These financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business and do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above.

***Basis of Presentation*** 

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"). The financial statements are presented in U.S. dollars.

***Basis of Consolidation*** 

The consolidated financial statements comprise the financial statements of 5E and its wholly owned subsidiaries, ABR, and 5EBA. In preparing the consolidated financial statements, all intercompany balances and transactions, income and expenses and profit and losses resulting from intra-company transactions have been eliminated.

***Concentrations of Risk*** 

The Company maintains cash deposits at several major banks, which at times may exceed amounts covered by insurance provided by the United States Federal Deposit Insurance Corporation. Management monitors the financial health of the banks and believes the Company is not exposed to any significant credit risk, and the Company has not experienced any such losses.

The Company's operations are predominately focused on the Project, which results in the Company being dependent upon a single mining operation in a single geographic region in the western United States in California. The geographic concentration of the Company's operations may disproportionately expose it to disruptions if the region experiences severe weather, transportation capacity constraints, constraints on the availability of required equipment, facilities, personnel or services, significant governmental regulation or natural disasters.

***Risks and Uncertainties*** 

The Company is subject to a number of risks that its management believes are similar to those of other companies of similar size and industry, including but not limited to, the success of its exploration activities, need for significant additional capital (or financing) to fund operating losses, competition from substitute products and services from larger companies, protection of proprietary technology, patent litigation, tariff and trade policy impacts on operating and construction costs, and dependence on key individuals. The Company currently generates no revenue from operations and will need to rely on raising additional capital or financing to sustain current and planned operations in the long term. There can be no assurance that management will be successful in its efforts to raise additional capital on terms favorable to the Company, or at all, or in management's ability to adequately reduce

------

expenses, if necessary, to maintain sufficient liquidity or capital resources. Refer to the Going Concern discussion above for additional details.

***Use of Estimates*** 

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates, assumptions, and allocations that affect amounts reported in the consolidated financial statements and related notes. Items that are subject to such estimates and assumptions include, but are not limited to, estimated useful lives and valuation of properties, plant and equipment, mineral rights and properties, deferred tax assets, estimation of future costs, useful life, and discount rates used to calculate the asset retirement obligations ("ARO"), assumptions used to value the embedded conversion option of the Convertible Notes (as further defined and described in Note 7–*Debt*), and fair value of stock-based compensation. Actual results could differ due to the uncertainty inherent in the nature of these estimates.

***Segment Information***

The Company has evaluated how it is organized and managed and has identified only one reportable business segment, which is the development of the Project. All of the Company's operations and assets are located in the United States. The operating results of the Company's single reportable segment are evaluated by the Company's Chief Executive Officer, who has been determined to be the Company's Chief Operating Decision Maker ("CODM"), to make key operating decisions, such as the allocation of resources and the evaluation of operating segment performance. The primary measure of profit and loss evaluated by the Company's CODM for its single reportable segment is consolidated net income. Consolidated net income, total assets, cash flows and all significant segment expense items are presented in the Company's consolidated financial statements and notes to the consolidated financial statements.

***Significant Accounting Policies*** 

*Convertible Debt*

Upon the issuance of convertible debt, the Company evaluates the embedded conversion features to determine whether the embedded conversion feature(s) should be bifurcated from the host instrument and accounted for separately as a derivative. If the conversion feature does not require derivative treatment, the instrument is evaluated for consideration of any beneficial conversion features. If a conversion feature is deemed to be beneficial, the intrinsic value of the conversion feature is recorded as additional paid in capital.

*Derivative Financial Instruments*

The Company records derivative instruments on the consolidated balance sheet at fair value as either an asset or a liability with changes in fair value recognized currently in earnings. Derivative financial instruments are classified as either current or non-current based upon the related classification of the host contract.

*Debt Issue Costs*

Costs incurred in connection with the issuance of debt are recorded as a reduction of the related debt and are amortized to interest expense over the life of the debt. Upon the extinguishment of the related debt, any remaining unamortized debt issue costs are written-off.

*Capitalized Interest*

The Company capitalizes a portion of its interest expense incurred on its Convertible Notes (as further described and defined in Note 7-*Debt)*. The amount capitalized is determined by multiplying the amount of interest expense incurred during the reporting period by the ratio of amounts capitalized to construction in progress with respect to the principal amount of Convertible Notes outstanding, and is limited to actual interest costs incurred during the period. The accumulated construction in progress balances included in the capitalized interest calculation begin when the costs are incurred and end when the asset is either placed into service or written off. Capitalized interest costs are then depreciated over the life of the related asset.

------

*Fair Value Measurements*

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The authoritative guidance requires disclosure of the framework for measuring fair value and requires that fair value measurements be classified and disclosed in one of the following categories:

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. The Company considers active markets as those in which transactions for the assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 - Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability. This category includes those derivative instruments that can be valued using observable market data. Substantially all of the inputs are observable in the marketplace throughout the full term of the derivative instrument, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace.

Level 3 - Measured based on prices or valuation models that require inputs that are both significant to the fair value measurement and less observable from objective sources (i.e., supported by little or no market activity).

Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy. The Company periodically reviews its inputs to ensure the fair value level classification is appropriate. When transfers between levels occur, it is the Company's policy to assume that the transfer occurred at the end of the period in which the change in circumstances that caused the transfer occurred.

The Company uses a Black-Scholes option valuation model to determine the grant date fair value of employee stock options which uses Level 2 inputs. See Note 11–*Share-Based Compensation* for a description of the inputs used. The Company uses a binomial lattice model to determine the fair value of its Convertible Notes and related Convertible Note Derivative, which uses Level 2 and Level 3 inputs, respectively. See Note 7–*Debt* and Note 8–*Convertible Notes Derivatives*, respectively, for a description of the inputs used.

*Cash and Cash Equivalents*

Cash and cash equivalents consist of cash and liquid investments with an original maturity when acquired of three months or less. As of June 30, 2025 and 2024, cash and cash equivalents consisted of $3.8 million and $4.9 million, respectively, of funds held in bank accounts with financial institutions in the United States.

*Mineral Rights and Properties and Exploration and Evaluation Costs*

Mineral property acquisition costs, including indirectly related acquisition costs, are capitalized when incurred. Acquisition costs include cash consideration.

Exploration and evaluation costs are classified as project expenses and expensed as incurred. When it is determined that a mining deposit can be economically and legally extracted or produced, development costs related to such reserves and incurred after such determination will be considered for capitalization. The establishment of proven and probable reserves is based on results of feasibility studies. Upon commencement of commercial production from the proposed commercial-scale facility, capitalized costs will be amortized over their estimated useful lives or units of production, whichever is a more reliable measure. Capitalized amounts relating to a property that is abandoned or otherwise considered uneconomic for the foreseeable future will be written off.

Drilling, development and related costs are either classified as project expenses and charged to operations as incurred, or capitalized, based on the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•whether the drilling or development costs relate to a project that has been determined to be economically feasible, and a decision has been made to put the project into production; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•whether, at the time the cost is incurred: (a) the expenditure embodies a probable future benefit that involves a capacity, singly or in combination with other assets, to contribute directly or indirectly to future net cash inflows, (b) the

------

Company can obtain the benefit and control others' access to it, and (c) the transaction or event giving rise to the right to or control of the benefit has already occurred.

*Impairment of Long-Lived Assets*

The carrying amount of long-lived assets is reviewed for impairment when events and circumstances indicate that such assets might be impaired. An asset is considered impaired when estimated future undiscounted cash flows are less than the carrying amount of the asset. In the event the carrying amount of such asset is not considered recoverable, the asset is adjusted to its fair value.

*Properties, Plant and Equipment*

Properties, plant and equipment are recorded at historical cost. Depreciation and amortization are provided in amounts sufficient to match the cost of depreciable assets to operations over their estimated service lives or productive value, whichever is shorter. Expenditures for improvements that significantly extend the useful life of an asset are capitalized. Expenditures for maintenance and repairs are charged to expense when incurred.

Assets under construction ("Construction in progress") include engineering costs related to the proposed commercial-scale facility, and will be depreciated in accordance with the Company's depreciation policy once placed in service.

*Asset Retirement Obligations*

The Company's mining, construction, exploration and development activities are subject to various laws and regulations, including legal and contractual obligations to reclaim, remediate, or otherwise restore properties at the time the related asset is removed from service. If a reasonable estimate of the fair value of an obligation to perform site reclamation, dismantle facilities, plug and abandon wells and neutralize the ore body after the completion of mining operations can be made, the Company records an asset retirement obligation liability (an "ARO") on its consolidated balance sheet and capitalizes the present value of the asset retirement cost in mineral rights and properties.

In general, the amount of the initial recorded ARO and the costs capitalized will equal the estimated future costs to satisfy the abandonment obligation assuming normal operation of the asset, using current prices that are escalated by an assumed inflation factor up to the estimated settlement date, which is then discounted back to the date that the abandonment obligation was incurred using the Company's credit adjusted risk-free rate. After recording these amounts, the ARO is accreted to its future estimated value and the original capitalized costs are amortized using the straight line method over the estimated life of the related asset. Accretion of the liability is included in project expenses in the statement of operations and the amortization of the original capitalized costs are included in depreciation and amortization expense in the Company's statement of operations (See Note 2–*Mineral Rights and Properties, Net* and Note 5–*Asset Retirement Obligations*).

For activities that do not qualify for asset capitalization, the costs associated with the obligation are charged to expense. Environmental compliance costs related to maintaining the existing permits are expensed in the period incurred.

Certain asset retirement obligations are secured by either certificate of deposits or surety bonds held for the benefit of the state of California or United States Environmental Protection Agency in amounts determined by applicable federal and state regulatory agencies. Reclamation bond deposits as of June 30, 2025 and 2024 were $1.5 million and $311 thousand, respectively.

*Leases*

The Company determines if a contractual arrangement is, or contains, a lease at the inception date. Right-of-use ("ROU") assets and liabilities related to operating leases are separately reported in the consolidated balance sheet. The Company has made an accounting policy election to exclude short-term leases (leases with a term of 12 months or less and which do not include a purchase option that the Company is reasonably certain to exercise) from the balance sheet presentation.

ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of the future lease payments over the lease term. When the rate implicit to the lease cannot be readily determined, the Company utilizes the Company's incremental borrowing rate in determining the present value of the future lease payments. The incremental borrowing rate is derived from information available at the lease commencement date

------

and represents the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. The ROU asset includes any lease payments made and lease incentives received prior to the commencement date. Operating lease ROU assets could also include any cumulative prepaid or accrued rent when the lease payments are uneven throughout the lease term. The ROU assets and lease liabilities may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.

Lease liabilities are increased by interest and reduced by payments each period, and the ROU asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the ROU asset result in straight-line rent expense over the lease term. Variable lease expenses are recorded when incurred.

*Financial Instruments*

The Company's financial instruments consist of cash and cash equivalents, the Convertible Notes, vehicle notes, and accounts payable and accrued liabilities. Management believes the Company is not exposed to significant interest, currency or credit risks arising from these financial instruments. The fair values of these instruments, due to their short-term nature, with the exception of the Convertible Notes and vehicle notes, approximate their carrying value. See Note 8–*Convertible Notes Derivatives* for fair value information related to the Convertible Notes.

*Share-Based Compensation*

The fair value of share-based compensation awards is measured at the date of grant and amortized over the requisite service period, which is generally the vesting period, with a corresponding increase in additional paid-in capital. The Company does not estimate the potential for forfeiture of share-based compensation awards when determining the fair value of awards on the grant date. In the case of a share-based compensation award that is either canceled or forfeited prior to vesting, the amortized expense associated with the unvested award is reversed.

*Loss per Common Share*

Basic loss per common share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding during the respective period. Diluted loss per share includes certain adjustments to basic net loss per share for income and to common shares outstanding for common stock equivalents and convertible instruments. See Note 12–*Earnings (Loss) Per Common Share* for details of any such adjustments.

*Income Taxes*

The Company uses the liability method of accounting for income taxes. Under this method, deferred income taxes are recorded to reflect the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts at each year-end.

In evaluating the Company's ability to recover its deferred tax assets, management considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In projecting future taxable income, the Company develops assumptions including the amount of future state and federal pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and the assumptions are consistent with the plans and estimates that the Company uses to manage the underlying business. A valuation allowance is recorded against deferred tax assets if the Company believes it is more likely than not the related tax benefits will not be realized.

The Company evaluates uncertain tax positions in a two-step process, whereby (i) it is determined whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position and (ii) for those tax positions that meet the more-likely-than-not recognition threshold, the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the related tax authority would be recognized.

*Contingencies*

Certain conditions may exist as of the date the Company's consolidated financial statements are issued that may result in a loss to the Company, but which will only be resolved when one or more future events occur or fail to occur. The Company's

------

management, with input from legal counsel, assesses such contingent liabilities, and such assessment inherently involves judgment. In assessing loss contingencies related to legal proceedings that are pending against the Company or unasserted claims that may result in proceedings, the Company's management, with input from legal counsel, evaluates the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein.

If the assessment of a contingency indicates that it is probable that a loss has been incurred and the amount of liability can be estimated, then the estimated undiscounted liability is accrued in the Company's consolidated financial statements. If the assessment indicates that a potentially material loss contingency is not probable but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, is disclosed. Actual results could vary from these estimates and judgments.

Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the guarantees would be disclosed.

Legal costs incurred in connections with loss contingencies are generally expensed when incurred as general and administrative costs.

*Reclassifications* 

Certain reclassifications have been made to prior years' reported amounts in order to conform to the current year presentation. These reclassifications did not impact our previously reported net income (loss), stockholders' equity or cash flows.

*Recently Issued and Adopted Accounting Pronouncements* 

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") that are adopted by the Company as of the specified effective date. Unless otherwise discussed, management believes that the impact of recently issued standards did not or will not have a material impact on the Company's consolidated financial statements upon adoption.

In November 2023, the FASB issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280) ("ASU 2023-07"). ASU 2023-07 is intended to enhance reportable segment disclosure requirements, including significant segment expenses and interim disclosures. The guidance allows for disclosure of multiple measures of a segment's profit or loss, and it requires that public entities with a single reportable segment provide all disclosures required by ASU 2023-07 and all existing disclosures required by the existing segment disclosure guidance. ASU 2023-07 is effective for annual reporting periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. The amendments are to be applied retrospectively, and early adoption is permitted. The Company adopted ASU 2023-07 effective June 30, 2025, and applied its provisions retrospectively to all periods presented in its consolidated financial statements (refer to *Segment Information* above for additional information).

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures ("ASU 2023-09"). ASU 2023-09 is intended to improve income tax disclosures primarily through enhanced disclosure of income tax rate reconciliation items, and disaggregation of income (loss) from continuing operations, income tax expense (benefit) and income taxes paid, net disclosures by federal, state, and foreign jurisdictions, among others. ASU 2023-09 is effective for annual reporting periods beginning after December 15, 2024, and early adoption is permitted. The Company plans to adopt ASU 2023-09 effective for its fiscal year ended June 30, 2026.

In November 2024, the FASB issued ASU 2024-03, Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses ("ASU 2024-03"), which requires the disaggregation of certain expenses in the notes of the financials, to provide enhanced transparency into the expense captions presented on the face of the income statement. In January 2025, the FASB issued Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date ("ASU 2025-01"), which clarified the effective dates of ASU 2024-03. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027 and may be applied either prospectively or retrospectively. The Company is currently evaluating the impact that ASU 2024-03 will have on its related disclosures, including the adoption date and transition method.

4. Properties, Plant and Equipment, Net

During the fourth fiscal quarter of 2024, the Company placed the SSF and its related injection and recovery wells, equipment and facilities into operation and therefore transferred approximately $75.9 million previously recorded as construction in progress to property plant and equipment. This amount represents the engineering services, equipment and construction costs related to the SSF and its related facilities, including any amounts of interest that were capitalized thereon. This amount was categorized into small-scale facility, injection and recovery wells, buildings and other plant and equipment, as appropriate. The Company intends to operate the SSF until we advance to the commercial construction stage for our proposed commercial facility, and therefore assigned a corresponding useful life. The useful life of the injection and recovery wells was based on their estimated productive life. The other assets placed into service will be depreciated in accordance with the Company's established estimated useful life policy.

---

(1)The effective interest rate represents a weighted-average interest rate applicable for the respective period, for the period of time which the Convertible Notes (as defined below) were outstanding. Interest expense utilized in the calculation is based upon the gross interest expense in the table above, and the principal balance utilized in the calculation is based on the ending net long-term debt applicable to each interest period inclusive of unamortized debt issuance costs and discount, changes in the principal balance resulting from the issuance of any Convertible Notes, interest paid-in-kind and any adjustments resulting from the Amended and Restated Note Purchase Agreement (as defined below).

***Convertible Notes - Background***

On August 11, 2022, the Company executed a $60.0 million private placement of senior secured convertible notes (the "August 2022 Notes") with Bluescape, which were secured by substantially all of the Company's assets. The August 2022 Notes bore interest at an annual rate of 4.5% if paid in cash, and 6.0% if paid through the issuance of additional notes. Interest was paid semi-annually on February 15 and August 15 of each year. The August 2022 Notes contained a financial covenant requiring the Company to maintain a cash balance of at least $10 million. Prior to fiscal year 2024, the Company elected to issue additional notes as payment for approximately $1.7 million of interest accrued on the August 2022 Notes during the period from issuance through June 30, 2023.

On August 15, 2023, the Company elected to issue additional notes as payment for approximately $1.9 million of interest accrued on the August 2022 Notes during the period from February 16, 2023 through August 15, 2023.

------

On January 18, 2024 (the "Modification Date"), the Company entered into an amended and restated note purchase agreement (the "January 2024 Amended and Restated Note Purchase Agreement") which modified certain terms of the August 2022 Notes, including (i) to extend the maturity date of the August 2022 Notes to August 15, 2028, (ii) a reduction to the conversion rate applicable to the August 2022 Notes, (iii) fifty percent (50%) of the outstanding August 2022 Notes being acquired by Ascend, (iv) increasing the annual interest rate to 10.0% if future interest was paid through the issuance of additional notes, and (v) waiver of the minimum cash covenant through June 28, 2024 and reduction in amount to $7.5 million.

On February 15, 2024, the Company elected to issue additional notes as payment for approximately $2.1 million of interest accrued on the August 2022 Notes during the period from August 16, 2023 through February 15, 2024.

On May 28, 2024, the Company entered into a second amendment ("Amendment No. 2") to the January 2024 Amended and Restated Note Purchase Agreement and agreed, among other things, to (i) issue and sell new senior secured convertible notes in substantially the same form and under the same terms as the August 2022 Notes, as amended, in an aggregate principal amount of $6.0 million (the "June 2024 Notes") to Bluescape and Ascend, (ii) a waiver of the minimum cash covenant through December 31, 2024, and (iii) amend and restate the January 2024 Amended and Restated Note Purchase Agreement in the form attached as Annex A to Amendment No. 2 (the "May 2024 Amended and Restated Note Purchase Agreement").

On August 15, 2024, the Company elected to issue additional notes as payment for approximately $3.4 million of interest accrued on the August 2022 Notes during the period from February 16, 2024 through August 15, 2024, and on the June 2024 Notes during the period from issuance through August 15, 2024.

On September 16, 2024, the Company entered into a third amendment ("Amendment No. 3") to the January 2024 Amended and Restated Note Purchase Agreement and agreed, among other things, to (i) issue and sell new senior secured convertible notes in substantially the same form and under the same terms as the June 2024 Notes, in an aggregate principal amount of $6.0 million (the "September 2024 Notes") to Bluescape and Ascend, and (ii) amend and restate the January 2024 Amended and Restated Note Purchase Agreement in the form attached as Annex A to Amendment No. 3 (the "September 2024 Amended and Restated Note Purchase Agreement").

On January 14, 2025, the Company entered into a fourth amendment ("Amendment No. 4") to the January 2024 Amended and Restated Note Purchase Agreement and agreed, among other things, to (i) issue and sell new senior secured convertible notes in substantially the same form and under the same terms as the September 2024 Notes, in an aggregate principal amount of $5.0 million (the "January 2025 Notes" and, together with the August 2022 Notes, the June 2024 Notes and the September 2024 Notes, the "Convertible Notes") to Bluescape and Ascend, and (ii) amend and restate the January 2024 Amended and Restated Note Purchase Agreement in the form attached as Annex A to Amendment No. 4 (as amended, the "Amended and Restated Note Purchase Agreement"). The Amended and Restated Note Purchase Agreement also extended the date to which the Company must comply with a financial covenant for the Company to maintain a cash balance of at least $7.5 million from December 31, 2024 to March 31, 2025 (the "Minimum Cash Covenant"). Concurrently with the execution of Amendment No. 4, the Company entered into the 2025 Restructuring Support Agreement, and other related agreements, as discussed in Note 1–*Description of Company and Summary of Significant Accounting.* 

On February 17, 2025, the Company elected to issue additional notes as payment for approximately $4.0 million of interest accrued on the August 2022 Notes and June 2025 Notes during the period from August 15, 2024 through February 15, 2025, and on the September 2024 Notes and January 2025 Notes during the period from their respective issuance through February 15, 2025.

In connection with its entry into the January 2024 Amended and Restated Note Purchase Agreement, May 2024 Amended and Restated Note Purchase Agreement, September 2024 Amended and Restated Note Purchase Agreement, and January 2025 Amended and Restated Note Purchase Agreement, the Company incurred approximately $2.6 million, $541 thousand, $454 thousand, and $283 thousand of debt issuance costs, respectively.

As discussed in Note 1–*Description of Company and Summary of Significant Accounting*, on March 4, 2025, at a special meeting of stockholders, the Company's stockholders voted in favor of the 2025 Out-of-Court Restructuring, and on March 5, 2025 the Exchange was completed and resulted in 13,586,524 shares of the Company's Common Stock issued to Bluescape and Ascend, the termination of the Amended and Restated Note Purchase Agreement and related Minimum Cash Covenant, and the extinguishment of all indebtedness owed by the Company under the Amended and Restated Note Purchase Agreement.

***Convertible Notes - Conversion Terms***

Prior to entering into the January 2024 Amended and Restated Note Purchase Agreement, the Company had the right to convert the Convertible Notes, including interest paid-in-kind, into shares of the Company's Common Stock based upon the

------

Company's Common Stock trading above certain threshold prices at certain dates. However, in connection with the January 2024 Amended and Restated Note Purchase Agreement, the Company's ability to convert the Convertible Notes and force conversion into Common Stock was eliminated.

Prior to the Exchange, the Convertible Notes, including accrued interest paid-in-kind, were convertible into shares of the Company's Common Stock at any time before the Convertible Notes matured, at conversion rates (the "Conversion Rates") applicable to each separate issuance of Convertible Notes, at the election of the holder of the Convertible Notes. In addition, the Amended and Restated Note Purchase Agreement provided for certain adjustments to the Conversion Rates to increase the number of shares of Common Stock issuable upon conversion of the Convertible Notes in the event of certain change of control transactions or other events specified in the Amended and Restated Note Purchase Agreement (a "Make-Whole Fundamental Change"). The adjustment to the Conversion Rates in the event of a Make-Whole Fundamental Change was to be based on the timing of a Make-Whole Fundamental Change and the trading price of the Common Stock at such time or the cash received by holders of the Common Stock in connection with such Make-Whole Fundamental Change.

The Conversion Rate applicable to the June 2024 Notes and September 2024 Notes was subject to adjustment if, after the issuance date of such notes and on or prior to December 31, 2024, the Company sold Common Stock or any other equity-linked securities in one or more transactions at an effective price per share that was less than the respective conversion price then in effect, subject to certain exemptions (a "Degressive Issuance"). In the event of a Degressive Issuance, the Conversion Rate applicable to the respective Convertible Notes was subject to adjustment based on the weighted average issuance price of the securities sold in such Degressive Issuance, as set forth in the Amended and Restated Note Purchase Agreement. As part of the August 2024 Equity Offering (as further described and defined in Note 10–*Equity*), a Degressive Issuance provision applicable to the June 2024 Notes resulted in an adjustment to the Conversion Rate applicable only to the June 2024 Notes. A Degressive Issuance did not occur with respect to the September 2024 Notes prior to the expiration of such feature on December 31, 2024.

During the period over which the Convertible Notes were outstanding, and prior to the Exchange, no holder of Convertible Notes elected to convert such Convertible Notes into the Company's Common Stock.

***Convertible Notes – Derivatives***

The terms of the Amended and Restated Note Purchase Agreement permitted a change to the Conversion Rates applicable to the June 2024 Notes and September 2024 Notes upon a Digressive Issuance by the Company on or before December 31, 2024. As a result, these conversion features were deemed to be embedded derivatives requiring bifurcation and separate accounting as stand-alone derivative instruments (the "June 2024 Convertible Note Derivative" and "September 2024 Convertible Note Derivative," respectively, and together, the "Convertible Note Derivatives") through December 31, 2024. The June 2024 Notes were initially recorded at their face amount of $6.0 million less debt issuance costs of $541 thousand and the fair value of the June 2024 Convertible Note Derivative, which was determined to be $4.1 million. Similarly, the September 2024 Notes were initially recorded at their face amount of $6.0 million less debt issuance costs of $454 thousand and the fair value of the September 2024 Convertible Note Derivative, which was determined to be $1.6 million.

The provisions that resulted in separate accounting for the Convertible Note Derivatives expired on December 31, 2024, and accordingly, the fair value of the Convertible Note Derivatives on such date was transferred to additional paid-in capital. Refer to Note 8–*Convertible Note Derivatives* and the discussion immediately below for additional details regarding the fair values of the Convertible Note Derivatives.

***Convertible Notes – Fair Value***

Fair value and carrying value information for the Convertible Notes as of June 30, 2024 follows. There were no Convertible Notes outstanding as of June 30, 2025.

(1)The reported fair value of the convertible note relates only to the debt component of such security and excludes the fair value associated with the related convertible note derivative that has been bifurcated and accounted for separately. Refer to Note 8–Convertible Note Derivatives for fair value information related to the Convertible Note Derivatives.

------

The fair value model for the Convertible Notes and related Convertible Note Derivatives requires the input of subjective assumptions including expected share price volatility, risk-free interest rate and debt rate. Changes in the input assumptions as well as the Company's underlying share price can materially affect the fair value estimates. Changes in the reported fair value of the Convertible Notes between periods are not recognized in net income and therefore have no effect on reported net income (loss).

The significant assumptions used in the fair value model for the Convertible Notes and related Convertible Note Derivatives include the following, with changes in volatility, debt rate and stock price having the most significant impact on the related fair values.

(2)Debt rates of 28.7% and 36.7% were utilized in the valuation of the August 2022 Notes and June 2024 Notes, respectively.

***January 2024 Convertible Notes – Loss on Extinguishment***

For accounting purposes, the modification of the terms of the Convertible Notes in connection with the January 2024 Amended and Restated Note Purchase Agreement was evaluated and determined to be representative of an in-substance extinguishment of the Convertible Notes outstanding at that date, and establishment of new debt, primarily due to the significance of the changes to the terms of the conversion features. As a result, the Company wrote-off the remaining principal, accrued interest, unamortized discount and debt issuance costs associated with the prior debt on the Modification Date and recognized the modified debt on the balance sheet at its fair value of $65.2 million. The fair value of the modified debt was determined utilizing a binomial lattice model, and the significant inputs to such model are described in more detail in the table under the heading *Convertible Notes – Fair Value* within this footnote. The difference in value between the prior debt and the modified debt resulted in a loss on extinguishment of debt of $21.0 million, the calculation of which is summarized in the following table.

***March 2025 Convertible Notes – Debt Exchange***

The Exchange Transaction described in Note 1–*Description of Company and Summary of Significant Accounting*, was evaluated for accounting purposes, and determined to constitute a single transaction that was accounted for as a troubled debt restructuring. The Exchange Transaction is considered a troubled debt restructuring as the Company was experiencing financial difficulty at the time of the transaction and the noteholders granted a concession to the Company. A concession was determined to be granted to the Company, as the fair value of equity interests received by the noteholders was less than the net carrying value of the long-term debt on such date.

In accordance with the accounting for troubled debt restructurings, the Company derecognized the remaining principal, accrued interest, unamortized discount and debt issuance costs associated with the Convertible Notes upon the effectiveness of the

------

Exchange Transaction, and recognized the equity interest issued to the noteholders at fair value, less issuance costs paid. Refer to Note 10–*Equity*, for information related to the determination of fair value of the equity interests issued and issuance costs paid. The difference in value between the prior debt and the fair value of the equity interest issued, less proceeds received by the Company in the Exchange Transaction, resulted in a gain on extinguishment of debt of approximately $17.3 million, the calculation of which is summarized in the following table.

---

The gain on extinguishment of debt decreased basic loss per share of Common Stock for the year ended June 30, 2025, by $2.17.

8. Convertible Notes Derivatives

The June 2024 Convertible Note Derivative and September 2024 Convertible Note Derivative, each which relate to the June 2024 Notes and September 2024 Notes, respectively, described in Note 7–*Debt*, were valued upon initial recognition and at each reporting period at fair value using a with-and-without methodology utilizing a binomial lattice model (a model which utilizes Level 3 fair value inputs).

The valuation model for the Convertible Note Derivatives requires the input of subjective assumptions including expected share price volatility, risk-free interest rate and debt rate. Refer to *Convertible Notes*–*Fair Value* in Note 7–*Debt* for a table of certain inputs utilized in the valuation of the Convertible Notes and related Convertible Notes Derivatives on certain dates. Changes in the input assumptions as well as the Company's underlying share price can materially affect the fair value estimates.

Changes in the fair value between periods were recognized in Derivative gain (loss) in the statement of operations but had no related impact on the Company's cash position or cash flows. The provision that resulted in separate accounting for the June 2024 Convertible Note Derivative began June 11, 2024 in connection with the issuance of the June 2024 Notes, and on September 16, 2024 for the September 2024 Convertible Note Derivative in connection with the issuance of the September 2024 Notes. Each of these provisions expired on December 31, 2024, and accordingly, the Convertible Note Derivatives were derecognized and the remaining fair values were transferred to additional paid-in capital.

The components of changes to the fair value of the Convertible Note Derivatives for the periods presented is summarized below.

9. Financial Instruments and Fair Value Measurements

At June 30, 2025, cash equivalents as well as trade and other payables approximated their fair value due to their short-term nature. The Company's financial instruments also consist of environmental reclamation bonds which are invested in certificates of deposit and money market funds which are classified as Level 1. The Convertible Notes and Convertible Note Derivatives were classified as Level 2 and Level 3, respectively, while outstanding. Fair value disclosures related to the Convertible Notes and the reconciliation of changes in the fair value of the Convertible Note Derivatives can be found in Note 7–*Debt* and Note 8–*Convertible Note Derivatives, respectively*.

## 10 . Equity
The Company is authorized to issue up to 360,000,000 shares of common stock, par value $0.01 per share, and 20,000,000 shares of preferred stock, par value, $0.01 per share. The Company has no outstanding shares of preferred stock.

***2024 Out-of-Court Restructuring***

On January 18, 2024, as part of the 2024 Out-of-Court Restructuring, and pursuant to a subscription agreement with Ascend, dated December 5, 2023 and an amended and restated subscription agreement with 5ECAP LLC ("5ECAP"), dated January 18, 2024 (the "5ECAP Subscription Agreement"), the Company issued (i) 233,298 shares of Common Stock to Ascend at a price of $23.575 per share, which shares included the placement fee to Ascend in shares of Common Stock and (ii) 233,298 shares of Common Stock to 5ECAP at a price of $23.575 per share, which shares included the placement fee to 5ECAP in shares of Common Stock. Then, on January 29, 2024, also as part of the 2024 Out-of-Court Restructuring and pursuant to the 5ECAP Subscription Agreement, the Company issued an additional 361,611 shares of Common Stock to 5ECAP at a price of $23.575 per share. These transactions resulted in net proceeds to the Company of $15.8 million.

***August 2024 Equity Offering***

On August 27, 2024, the Company completed an offering (the "August 2024 Equity Offering") of (i) 231,884 shares (the "Shares") of Common Stock, (ii) Series A warrants to purchase up to an aggregate of up to 231,885 shares of Common Stock (the "Series A Warrants") and (iii) Series B warrants to purchase an aggregate of 231,885 shares of Common Stock (the "Series B Warrants", and collectively with the Series A Warrants, the "2024 Warrants"). The Shares and 2024 Warrants were offered and sold on a combined basis for consideration equating to $17.25 for one Share and two 2024 Warrants. This transaction resulted in net proceeds to the Company of approximately $3.0 million after deducting the placement agent's fees and other offering expenses. The aggregate net proceeds and issuance costs associated with the August 2024 Equity Offering were allocated to the Shares and 2024 Warrants based upon the relative fair value of such items on the offering date, which resulted in approximately $1.5 million allocated to the Shares and $1.5 million allocated to the 2024 Warrants.

***Convertible Notes Derivatives***

On December 31, 2024, the provisions that resulted in separate accounting for the Convertible Notes Derivatives expired, and accordingly, the Convertible Note Derivatives were derecognized and the remaining aggregate fair value of approximately $3.6 million was transferred to additional paid-in capital. Refer to Note 8–*Convertible Notes Derivatives*, for additional details.

***Debt Exchange Transaction***

As further described in Note 1–*Description of Company and Summary of Significant Accounting* and Note 7–*Debt*, the Exchange Transaction resulted in (i) the issuance of 13,586,524 shares of Common Stock issued in the Exchange for the termination of the Amended and Restated Note Purchase Agreement and the extinguishment of all indebtedness owed by the Company under the Amended and Restated Note Purchase Agreement, (ii) the issuance of 1,408,173 shares of Common Stock for an aggregate purchase price of $5.0 million in the March 2025 Subscription, and (iii) the issuance of Restructuring Warrants with a one-year term to purchase an aggregate 5,632,692 shares of Common Stock. For accounting purposes, and as described in Note 7–*Debt*, the Exchange Transaction was determined to constitute a single transaction accounted for as a troubled debt restructuring. As such, the equity interests issued in the Exchange Transaction were recognized in shareholders' equity at fair value on their respective issuance dates, less issuance costs incurred, which were allocated based upon the relative fair value of the underlying

During the years ended June 30, 2025 and 2024, the Company issued approximately 16 thousand shares and 4 thousand shares of its Common Stock, respectively, upon the vesting of equity awards. The vesting events did not result in any cash proceeds to the Company.

***Warrants***

The Series A Warrants and the Series B Warrants became exercisable on February 27, 2025. The Series A Warrants will expire on February 27, 2030 and the Series B Warrants will expire on February 27, 2027. The exercise price for each of the 2024 Warrants is $18.3563 per share. The Restructuring Warrants were exercisable upon issuance and will expire on March 13, 2026. The exercise price for the Restructuring Warrants is $3.5507 per share.

The 2024 Warrants and Restructuring Warrants (collectively, the "Warrants") contain standard adjustments to the exercise price including for stock splits, stock dividends, rights offerings and pro rata distributions.

The Warrants include cashless exercise rights to the extent the resale of the shares of Common Stock underlying the Warrants is not registered under the Securities Act.

***2024 Equity Distribution Agreement***

On March 28, 2024, the Company entered into an equity distribution agreement (the "Equity Distribution Agreement") with Canaccord Genuity LLC and D.A. Davidson & Co. (the "Agents") pursuant to which the Company may offer and sell up to $15.0 million of shares of Common Stock from time to time through the Agents, acting as the Company's sales agents, or directly to one or more of the Agents, acting as principal (the "ATM Program").

As a result of the August 2024 Equity Offering, the Company was precluded from utilizing the ATM Program for one year following the closing of the offering, and as a result approximately $410,000 of costs previously capitalized for the ATM Program were written-off to general and administrative expense during the year ended June 30, 2025. On August 14, 2025, the Equity Distribution Agreement was terminated pursuant to the terms therein. The Company is not subject to any termination penalties related to the termination of the Equity Distribution Agreement. The Company did not sell any shares of its common stock under the Equity Distribution Agreement.

11. Share Based Compensation

***2022 Equity Compensation Plan*** 

In March 2022, the Board adopted the 5E Advanced Materials, Inc. 2022 Equity Compensation Plan (the "5E Incentive Plan"), which was approved by our shareholders in April 2023, which reserved approximately 109 thousand shares of Common Stock for issuance under the 5E Incentive Plan. In October 2024, the Board adopted an amendment to the 5E Incentive Plan, which was approved by our shareholders in January 2025, which reserved approximately 217 thousand additional shares for issuance under the 5E Incentive Plan. Finally, in January 2025, the Board adopted an Amended and Restated 5E Incentive Plan (the "Restated Incentive Plan"), which was approved by our shareholders in March 2025, which reserved approximately 609 thousand additional shares for issuance under the Restated Incentive Plan, for an aggregate of approximately 935 thousand shares reserved for issuance under the Restated Incentive Plan. The Restated Incentive Plan authorizes the grant of stock options, restricted share units ("RSUs"), performance share units ("PSUs"), performance cash units and other equity-based awards. The Company's Compensation Committee determines the exercise price for stock options and other equity-based awards, which may not be less than the fair market value of the Company's common stock on the date of grant. As of June 30, 2025, approximately 198 thousand shares remain available for issuance under the Restated Incentive Plan. It is the Company's policy to issue new shares of Common Stock to satisfy stock option exercises. Approval for awards issued to directors under the Restated Incentive Plan during the year ended June 30, 2025 was obtained under ASX Listing Rule 10.14.

***Share-Based Compensation Expense***

Share-based compensation expense is included in general and administrative expense and represents costs associated with RSUs, PSUs and options granted to directors, employees and consultants of the Company. Share-based compensation expense consisted of the following for the periods presented.

As of June 30, 2025, the Company had approximately $2.1 million of total unrecognized stock-based compensation expense related to unvested stock-based compensation awards that is expected to be recognized over a weighted average period of approximately 1.8 years.

***Stock Options***

All stock options outstanding prior to September 30, 2022 were granted under the predecessor parent company's employee share option plan (the "ABR Employee Share Option Plan"). New option grants are made under the Restated Incentive Plan and vest ratably over the vesting period, which is generally three years or less. The fair value of stock option awards granted to directors, officers, employees and/or consultants is estimated on the grant date using the Black-Scholes option valuation model. Volatility is determined using the Company's historical stock price information. The significant assumptions used to estimate the fair value of stock option awards granted during the years ended June 30, 2025 and 2024, respectively, using the Black-Scholes option valuation model are as follows.

The weighted average remaining life of vested options as of June 30, 2025 and 2024, was approximately 5.0 years and 1.4 years, respectively. As of June 30, 2025 and 2024, the maximum expiration date for vested options was approximately 7.8 and 8.8 years, respectively.

As of June 30, 2025, there was approximately $1.8 million of unrecognized compensation cost related to 619 thousand unvested stock options. This cost is expected to be recognized over a weighted-average remaining period of approximately 1.9 years. As of June 30, 2025 and 2024, the maximum expiration date for unvested options was approximately 3.9 and 3.1 years, respectively.

During the year ended June 30, 2024, approximately 12 thousand options with a remaining term of approximately 1.9 years and an exercise price of $589.26, granted to one grantee, were cancelled and concurrently replaced with approximately 2 thousand RSUs that vest over two years. The modification did not result in any incremental compensation expense.

(1)During the year ended June 30, 2024, approximately 5.3 thousand PSUs were granted, which based on the achievement of certain financial and operational targets, could vest within a range of 0% to 100%. The targets are 1) construction of the proposed commercial-scale facility commencing prior to September 1, 2026; 2) the budget for the proposed commercial-scale facility within a range of $342-418 million; and 3) an approved final investment decision in the proposed commercial-scale facility at a modeled internal rate of return of 20%. The determination of the percentage of shares that ultimately vest will be made at the three-year anniversary of the grant date based upon achievement of the performance targets over the period.

(1)During the year ended June 30, 2025, approximately 19.8 thousand PSUs were granted, which based on the achievement of certain financial and operational targets, could vest within a range of 0% to 100%. The targets are 1) construction of the proposed commercial-scale facility commencing prior to September 1, 2026; 2) an approved final investment decision in the proposed commercial-scale facility at a modeled internal rate of return of 20%, 3) achievement of an enterprise value in excess of $200 million, and 4) achievement of an enterprise value in excess of $300 million. The determination of the percentage of shares that ultimately vest will be made at the three-year anniversary of the grant date based upon achievement of the performance targets over the period.

12. Earnings (Loss) Per Common Share

Basic loss per share is computed by dividing the net loss available to common stockholders by the weighted average number of common shares outstanding during the respective period. Diluted loss per share includes certain adjustments to basic loss per share for income and to common shares outstanding that could occur if RSUs, PSUs, stock options and convertible securities such as the Convertible Notes and Warrants were exercised or converted into common stock. Diluted loss per share equals basic loss per share for the years ended June 30, 2025 and 2024, as the effect of including dilutive securities in the calculation would be antidilutive.

For the years ended June 30, 2025 and 2024, the following effects are excluded from the computation of dilutive loss per share as such effects would have an anti-dilutive effect.

|  | **2025** | **2024** |

(1)In accordance with the relevant authoritative guidance, this represents the shares that would have been issued if noteholders had elected to convert the Convertible Notes into shares of Common Stock based upon the principal balance and Conversion Rate applicable at the beginning of the respective period, or at the issuance date of such Convertible Notes, if later.

***Subsequent Equity Issuance – August 2025***

As discussed in Note 16–*Subsequent Events*, subsequent to June 30, 2025, the Company issued an aggregate of 2,374,481 shares of its Common Stock in connection with the August 2025 Equity Offering (as defined in Note 16–*Subsequent Events*). The impact of the equity issuance is not reflected in the computation of earnings per share for the year ended June 30, 2025.

13. Defined Contribution Plan

The Company sponsors a defined contribution plan under Section 401(k) of the Internal Revenue Code. This plan covers all of the Company's employees that have attained the age of 21 and have completed three months of service to the Company. The Company matches employee deferrals 100% up to 4% and 50% up to 6% of an employee's eligible earnings, subject to limitations imposed by the Internal Revenue Service. The Company's contributions to this plan were $107 thousand and $183 thousand for the years ended June 30, 2025 and 2024, respectively.

14. Commitments and Contingencies

***Purchase Obligations*** 

As of June 30, 2025, the Company had purchase order commitments of approximately $3.5 million primarily for drilling and other services related to the Company's wellfield development program, raw materials for the operation of the SSF, engineering services and vendor tested related to the design of the proposed commercial-scale facility, environmental testing and other corporate services.

***Litigation***

On July 17, 2023, the Company filed a complaint (the "Complaint") against a previous construction contractor in the United States District Court for the Central District of California, Eastern Division, alleging, among other things, numerous breaches by the contractor of its contractual obligations to 5EBA under the Procurement and Construction Contract, effective April 26, 2022, by and between 5EBA and the contractor, relating to the construction of the SSF in California (the "Contract"). On August 10, 2023, the contractor filed an answer to the Complaint as well as a counterclaim for, among other things, alleged breaches by 5EBA of its contractual obligations to the contractor under the Contract and has requested relief in the approximate amount of $5.5 million. The Company has filed a response disputing the counterclaims asserted by the contractor. Discovery has begun and is ongoing. During July 2025, the Company and contractor attended mediation, which did not result in a resolution relating to the litigation. An estimate of reasonably probable outcomes cannot be made at this time.

15. Income Taxes

The Company recorded U.S. current income tax expense in connection with the Exchange during the fiscal year ended June 30, 2025. No U.S. federal or state income tax benefit was recorded for losses incurred during the year ended June 30, 2024. The Company has concluded that it is more likely than not that its deferred tax assets will not be realized which resulted in the recording of a full valuation allowance during those periods.

Domestic and foreign components of loss before income taxes for the years ended June 30 are as follows.

As of June 30, 2025, the Company had U.S. federal, state, and Australian net operating loss ("NOL") carryforwards of $67.7 million, $40.7 million and $14.6 million, respectively. As of June 30, 2024, the Company had U.S. federal, state, and Australian NOL carryforwards of $85.3 million, $74.0 million and $9.4 million, respectively. U.S. net operating loss carryforwards for the periods arising before December 31, 2018 have a 20 year carryforward, the earliest of which could expire in 2037. The amount of the post-tax reform U.S. federal NOL generated after tax year 2017 of approximately $66.8 million, can be carried forward indefinitely. California net operating losses have a 20-year carryforward, the earliest of which could expire beginning in 2037. Australia net operating losses can be carried forward indefinitely.

The utilization of the Company's net operating loss or tax attributes are subject to annual limitations in accordance with IRC section 382 and similar state provisions resulting from certain ownership changes that occurred. Such an annual limitation could result in the expiration of the attributes before utilization. The federal and state NOL carryforwards at June 30, 2025 have been reduced to reflect IRC section 382 ownership changes through June 30, 2025 and resultant inability to utilize a portion of the NOL prior to its expiration due to annual limitations.

The Company evaluates both the positive and negative evidence available to determine the realizability of its deferred tax assets. As of June 30, 2025 and 2024, the Company had a valuation allowance of $35.6 million and $39.4 million, respectively, of which both primarily relate to net operating losses and exploration costs.

Changes in the balance of the Company's deferred tax asset valuation allowance for the periods presented are as follows:

---

| | | |
|:---|:---|:---|
|  | **Year ended June 30,** | **Year ended June 30,** |
|  | **2025** | **2024** |
|  | ($ in thousands) | ($ in thousands) |
| &nbsp;&nbsp;&nbsp;&nbsp;Valuation allowance | $(3803) | $14621 |

---

The Company had no unrecognized tax benefits as of June 30, 2025 or 2024. The Company recognizes interest accrued related to unrecognized tax benefits and penalties in its income tax provision, if applicable. The Company has not recognized any interest or penalties in the periods presented in these financial statements. The Company is subject to income tax in the U.S. federal jurisdiction, California and Australia. Tax years 2021 and forward remain subject to examination but there are currently no ongoing exams in any taxing jurisdictions.

16. Subsequent Events

***Enactment of Tax Legislation***

On July 4, 2025, President Trump signed into law legislation formally titled An Act to Provide for Reconciliation Pursuant to Title II of H. Con. Res. 14 (the "Act"), commonly referred to as the One Big Beautiful Bill Act ("OBBB"). The Act primarily makes permanent many of the tax provisions originally enacted under the Tax Cuts and Jobs Act of 2017 ("TCJA") and introduces modifications to certain U.S. corporate tax provisions. The Company is currently evaluating the impact of the Act and does not expect it to have a material effect on the Company's financial statements as of June 30, 2025.

***August 2025 Equity Offering***

On August 21, 2025, the Company entered into an underwriting agreement to issue and sell an aggregate of 2,374,481 shares of its Common Stock at a price of $3.50 per share (the "August 2025 Equity Offering"). The August 2025 Equity Offering closed on August 25, 2025, and resulted in aggregate proceeds of approximately $8.31 million before deducting underwriting discounts and commissions, and other offering expenses payable by the Company.

## Item 9A. Controls and Procedures
***Evaluation of Disclosure Controls and Procedures*** 

The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company's disclosure controls and procedures as of June 30, 2025 (the "Evaluation Date"). Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on that evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective at the reasonable assurance level as of the Evaluation Date.

***Management's Annual Report on Internal Control Over Financial Reporting***

Our management, with the participation of our Chief Executive Officer and Chief Financial Officers, is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, for the Company.

Our internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP"), and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Management conducted an evaluation of the effectiveness of our internal control over financial reporting, as of the Evaluation Date, based on the framework set forth in Internal Control-Integrated Framework 2013 issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its evaluation under this framework, management concluded that our internal control over financial reporting was effective at the reasonable assurance level as of the Evaluation Date.

This annual report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting due to an exemption established by the JOBS Act for "emerging growth companies."

***Changes in Internal Control Over Financial Reporting*** 

There were no changes in the Company's internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

***Australian Disclosure Requirements***

In addition to the Company's primary Nasdaq listing, Common Stock are also quoted in the form of CHESS Depositary Interests ("CDIs") on the Australian Securities Exchange ("ASX") and trade under the code "5EA". As part of our ASX listing, we are required to comply with certain of the disclosure and other obligations set out in the ASX Listing Rules. The following information is provided in accordance with the requirements of the ASX and the ASX Listing Rules (where that information has not been provided elsewhere in this Annual Report).

*Place of Incorporation and Restrictions on the Acquisition of Securities*

The Company is incorporated in the State of Delaware and is registered as a foreign company in Australia under the Corporations Act (ARBN 665 137 170). As a foreign company, the Company is not subject to Chapters 6, 6A, 6B or 6C of the Corporations Act (dealing with the acquisition of its shares, including substantial holdings and takeovers).

Under the Delaware General Corporation Law, shares in the Company are generally freely transferable. Transfers may, however, be subject to restrictions imposed by United States federal or state securities laws, by the Company's Certificate of Incorporation or Bylaws, or by an agreement signed with the holders of shares on issue.

The Company's Certificate of Incorporation and Bylaws do not impose any specific restrictions on the transfer of the Company's shares. Transfers of the Company's shares will be made only on the transfer books of the Company or by a transfer agent designated to transfer the Company's shares.

Repurchases of the Company's securities are governed by the safe harbor provisions set forth in Rule 10B-18 of the Securities Exchange Act of 1934. However, provisions of the Delaware General Corporation Law, the Company's Certificate of Incorporation and Bylaws could make it more difficult to acquire the Company by means of a tender offer (takeover), a proxy contest or otherwise, or to remove incumbent officers and directors of the Company. These provisions could discourage certain types of coercive takeover practices and takeover bids that the Company's Board may consider inadequate and encourage persons seeking to acquire control of the Company to first negotiate with the Board.

*Issued Capital*

As of August 31, 2025, the Company had 22,441,260 shares of Common Stock on issue, of which:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•22,441,260 shares of Common Stock were held by 17 stockholders and quoted on Nasdaq. (Note: The actual number of stockholders is greater than this number and includes holders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. The number of active holders of record also do not include holders whose shares may be held in trust by other entities.); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•1,483,299 shares of Common Stock were held by CHESS Depositary Nominees Pty Ltd (as Depositary Nominee) on behalf of 3,267 CDI holders, representing 14,832,990 CDIs quoted on ASX.

In addition, as of August 31, 2025, the Company had the following unquoted securities on issue which entitle the holder (upon vesting) to be issued Common Stock:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•646,487 unquoted options, held by 10 option holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•9,716 Restricted Share Units, held by 20 employees of the Company pursuant to the Company's Amended and Restated 2022 Equity Compensation Plan; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•22,801 Performance Share Units, held by 7 employees of the Company pursuant to the Company's Amended and Restated 2022 Equity Compensation Plan.

*Voting Rights*

Each holder of Common Stock is entitled to one vote per Common Stock held. Holders of CDIs are entitled to receive notice of, and to attend as guests (but not vote at) meetings of stockholders. Holders of CDIs are the beneficial owner of one share of Common Stock for every 10 CDIs held. The Depositary Nominee (or its custodian) is the legal holder of the Common Stock underlying the CDIs.

As the beneficial owners, holders of CDIs may:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•direct the Depositary Nominee (or its custodian) how to vote the Common Stock represented by their CDIs by completing the CDI Voting Instruction Form that accompanies the relevant notice of meeting or proxy statement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•(if applicable) appoint themselves (or another person) to be the Depositary Nominee's proxy with respect to the Common Stock represented by their CDIs for the purposes of attending and voting at the meeting by completing the CDI Voting Instruction Form that accompanies the relevant notice of meeting or proxy statement.

Alternatively, holders of CDIs can elect to convert their CDIs into Common Stock and vote those Common Stock at the meeting. Such conversion must be completed prior to the record date fixed by the Company for determining the entitlement of stockholders to attend and vote at the meeting.

Options, Restricted Share Units and Performance Share Units do not carry voting rights.

*Distribution of CDI Holders*

Below is a distribution schedule of the number of holders of CDIs, as of August 31, 2025 and assuming all shares of Common Stock are held as CDIs.

## Exhibit 4.1

**Exhibit 4.1**

# DESCRIPTION OF CAPITAL STOCK

## Description of Capital Stock
The following description of our capital stock is a summary. The following description of our securities is not complete and may not contain all the information you should consider before investing in our securities. This description is summarized from, and qualified in its entirety by reference to, the complete text of our Amended and Restated Certificate of Incorporation and Bylaws are each included as exhibits to the registration statement of which this prospectus forms a part and are incorporated by reference herein.

Our authorized capital stock is 380,000,000 shares divided into 360,000,000 shares of common stock, par value of $0.01 per share, and 20,000,000 shares of preferred stock, par value of $0.01 per share.

## Common Stock
Except as otherwise required by law, as provided in our Amended and Restated Certificate of Incorporation or as provided in the resolution or resolutions, if any, adopted by our Board of Directors (our "Board") with respect to any series of the preferred stock, the holders of our common stock will exclusively possess all voting power. Each holder of shares of common stock will be entitled to one vote for each share held by such holder. Our Amended and Restated Certificate of Incorporation and Bylaws provide that holders of one-third (1/3) in voting power of the shares entitled to vote, present in person or represented by proxy, will constitute a quorum at all meetings of stockholders for the transaction of business. When a quorum is present, the affirmative vote of a majority of the votes cast is required to take action, unless otherwise specified by law, our Bylaws or our Amended and Restated Certificate of Incorporation, and except for any action to amend, alter or repeal our Bylaws, which shall require the affirmative vote of at least 66 2/3% of the voting power of the shares of then-outstanding voting stock entitled to vote generally in the election of directors, voting together as a single class. Subject to the rights of holders of any series of outstanding preferred stock, holders of shares of our common stock will have equal rights of participation in the dividends and other distributions in cash, stock or property of the Company when, as and if declared thereon by our Board from time to time out of assets or funds legally available therefor and will have equal rights to receive the assets and funds of the Company available for distribution to stockholders in the event of any liquidation, dissolution or winding up of the affairs of the Company, whether voluntary or involuntary.

## CDIs
CDIs confer the beneficial ownership of our common stock on each CDI holder, with the legal title to such securities held by an Australian depositary entity, CHESS Depositary Nominees Pty Ltd. (the "Depositary Nominee"). The Depositary Nominee will be the registered holder of those shares of our common stock held for the benefit of holders of CDIs. The Depositary Nominee does not charge a fee for providing this service. Ten CDIs will represent an interest in one share of our common stock. Holders of CDIs will not hold the legal title to the underlying shares of our common stock to which the CDIs relate, as the legal title will be held by the Depositary Nominee. Each holder of CDIs will, however, have a beneficial interest in the underlying shares in our common stock. Each holder of CDIs that elects to vote at a stockholders meeting will be entitled to one vote for every 10 CDIs held by such holder. In order to vote at a stockholder meeting, a CDI holder may:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•instruct the Depositary Nominee, as legal owner of the shares of common stock, to vote the common stock represented by their CDIs to vote the shares of our common stock represented by their CDIs in a particular manner. A voting instruction form will be sent to holders of CDIs and must be completed and returned to the share registry for the CDIs prior to a record date fixed for the relevant meeting, or the Voting Instruction Receipt Time, which is notified to CDI holders in the voting instructions included in a notice of meeting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•inform us that they wish to appoint themselves or a third party as the Depositary Nominee's proxy with respect to our shares of common stock underlying the holder's CDIs for the purposes of attending and voting at the meeting. The instruction form must be completed and returned to the share registry for the CDI prior to the CDI Voting Instruction Receipt Time; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•convert their CDIs into shares of our common stock and vote those shares at the meeting. The conversion must be undertaken prior to a record date fixed by the Board for determining the entitlement of members to attend and vote at the meeting. If the holder later wishes to sell their investment on the ASX, it would first be necessary to convert those shares of common stock back to CDIs. Further details on the conversion process are set out below.

Voting instruction forms and details of these alternatives are included in each notice of meeting sent to CDI holders by the Company.

------

## *Conversion of CDIs to shares of Common Stock* 
CDI holders may at any time convert their CDIs to a holding of shares of common stock by instructing the share registry for the CDIs, either:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Directly in the case of CDIs held on the issuer sponsored sub-register operated by the Company (holders of CDIs will be provided with a CDI issuance request form to return to the share registry for the CDIs); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Through their "sponsoring participant" (usually their broker) in the case of CDIs which are held on the CHESS sub-register (in this case, the sponsoring broker will arrange for completion of the relevant form and its return to the share registry for the CDIs).

In both cases, once the share registry for the CDIs has been notified, it will arrange the transfer of the relevant number of shares of common stock from the Depositary Nominee into the name of the CDI holder in book entry form or, if requested, deliver the relevant shares of common stock to their DTC participant in the United States Central Securities Depositary. The share registry for the CDIs will not charge a fee for the conversion (although a fee may be payable by market participants). Holding shares of common stock will, however, prevent a person from selling their shares of common stock on the ASX, as only CDIs can be traded on that market.

*Conversion of shares of Common Stock to CDIs*

Shares of common stock may be converted into CDIs and traded on the ASX. Holders of shares of common stock may at any time convert those shares to CDIs by contacting the Company's transfer agent. The underlying shares of common stock will be transferred to the Depositary Nominee, and CDIs (and a holding statement for the corresponding CDIs) will be issued to the relevant security holder. No trading in the CDIs may take place on the ASX until this conversion.

The Company's transfer agent will not charge a fee to a holder of shares of common stock seeking to convert their shares of common stock to CDIs, although a fee may be payable by market participants.

In either case, it is expected that each of the above processes will be completed within 24 hours, provided that the Company's transfer agent is in receipt of a duly completed and valid request form. No guarantee can, however, be given about the time required for this conversion to take place.

## Dividends and Other Shareholder Entitlements
Holders of CDIs are entitled to receive all the direct economic benefits and other entitlements in relation to the underlying shares of common stock that are held by the Depositary Nominee, including dividends and other entitlements that attach to the underlying shares of common stock.

It is possible that marginal differences may exist between the resulting entitlement of a holder of CDIs and the entitlements that would have accrued if a holder of CDIs held their holding directly as shares of common stock. As the ratio of CDIs to common stock is not one-to-one, and any entitlement will be determined on the basis of shares of common stock rather than CDIs, a holder of CDIs may not always benefit to the same extent (e.g. from the rounding up of fractional entitlements). We will, however, be required by the ASX Settlement Rules to minimize any such differences where legally permissible. If a cash dividend or any other cash distribution is declared in a currency other than Australian dollars, we currently intend to convert that dividend or other cash distribution to which a holder of CDIs is entitled to Australian dollars and distribute it to the relevant holder of CDIs in accordance with their entitlement.

Due to the need to convert dividends from United States dollars to Australian dollars in the above mentioned circumstances, holders of CDIs may potentially be advantaged or disadvantaged by exchange rate fluctuations, depending on whether the Australian dollar weakens or strengthens against the United States dollar during the period between the resolution to pay a dividend and conversion into Australian dollars.

## Takeovers
If a takeover bid is made in respect of any of our common stock of which the Depositary Nominee is the registered holder, the Depositary Nominee is prohibited from accepting the offer made under the takeover bid except to the extent that acceptance is authorized by the CDI holders in respect of the shares of common stock represented by their holding of CDIs.

------

The Depositary Nominee must accept a takeover offer in respect of shares of common stock represented by a holding of CDIs if the relevant holder of CDIs instructs it to do so and must notify the entity making the takeover bid of the acceptance.

## Preferred Stock
Our Board is authorized to provide, out of the unissued shares of preferred stock, for one or more series of preferred stock and, with respect to each such series, to fix the number of shares constituting such series and the designation of such series, the voting powers, if any, of the shares of such series, and the preferences and relative, participating, optional or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares of such series, as are stated in the resolution or resolutions providing for the issuance of such series adopted by the Board. The authority of the Board with respect to each series of preferred stock includes determination of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the designation of the series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the number of shares of the series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the dividend rate or rates on the shares of that series, whether dividends will be cumulative and, if so, from which date or dates, and the relative rights of priority, if any, of payment of dividends on shares of that series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•whether the series will have voting rights in addition to the voting rights provided by law and, if so, the terms of such voting rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•whether the series will have conversion privileges and, if so, the terms and conditions of such conversion, including provision for adjustment of the conversion rate in such events as the Board determines;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•whether or not the shares of that series will be redeemable, in whole or in part, at the option of the Company or the holder thereof and, if made subject to such redemption, the terms and conditions of such redemption, including the date or dates upon or after which they will be redeemable, and the amount per share payable in case of redemptions, which amount may vary under different conditions and at different redemption rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the terms and amount of any sinking fund provided for the purchase or redemption of the shares of such series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the rights of the shares of that series in the event of voluntary or involuntary liquidation, dissolution or winding up of the Company, and the relative rights of priority, if any, of payment of shares of that series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the restrictions, if any, on the issue or reissue of any additional preferred stock; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•any other relative rights, preferences and limitations of that series.

## Investor Designation Rights
Pursuant to the terms of an investor and registration rights agreement to which we are a party, each of BEP Special Situations IV LLC and Ascend Global Investment Fund SPC for and on behalf of Strategic SP has the right to designate two individuals to our Board, and we are required to appoint or nominate such persons to our Board. Such party's respective designation right will continue for so long as each such party beneficially owns 25% of our common stock, and one director to serve on the Company's Board for so long as each such party beneficially owns 10% of our common stock, in each case including any shares of common stock previously issued or issuable to such party in connection with its exercise of the warrants issued to such party on March 13, 2025, and otherwise without regard to any of the limitations on exercise of such warrants. The size of our Board was also reduced to four directors pursuant to the terms of this agreement.

**Exhibit 19.1**

**5E Advanced Materials, Inc.** 

**INSIDER TRADING POLICY**

**(dated July 13, 2023)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**I.** **INTRODUCTION**

United States federal and state laws as well as the Corporations Act of Australia prohibit buying, selling or making other transfers of securities by persons who have material information that is not generally known or available to the public. These laws also prohibit persons with such Material Nonpublic Information (as further defined below) from disclosing this information to others who trade.

5E Advanced Materials, Inc. (the "**Company**") has adopted the following policy (this "**Policy**") regarding trading in securities by directors, officers, employees and consultants who have Material Nonpublic Information.

You are responsible for ensuring that you do not violate United States federal or state securities laws or this Policy. We designed this Policy to promote compliance with applicable securities laws, Australian securities laws, and to protect the Company and you from the serious liabilities and penalties that can result from violations of these laws.

If you violate the insider trading laws, you may have to pay significant civil and criminal fines. You also may have to serve a jail sentence. In addition, the Company may face significant civil penalties, as well as criminal fines

The United States Securities and Exchange Commission ("**SEC**"), Nasdaq Stock Market ("**Nasdaq**"), Australian Securities and Investments Commission ("**ASIC**") and Australian Securities Exchange ("**ASX**"), are very effective at detecting and pursuing insider trading cases. The SEC has successfully prosecuted cases against employees trading through foreign accounts, trading by family members and friends, and trading involving only a small number of shares. Therefore, it is important that you understand the breadth of activities that constitute illegal insider trading. This Policy sets out the Company's policy in the area of insider trading and should be read carefully and complied with fully.

This Policy will be reviewed, evaluated and revised by the Company from time to time in light of legal and regulatory changes, developments in the Company's business and other factors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**II.** **POLICIES AND PROCEDURES**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.** **Trading Policy**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•You may not buy or sell a company's securities when you have Material Nonpublic Information about that company. This Policy against "insider trading" applies to trading in any Company securities, as well as to trading in the securities of other companies with whom the Company has a relationship, such as the Company's investees, customers and suppliers or a firm with which the Company is negotiating a major transaction (a "**Company Counterparty**").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•You may not convey Material Nonpublic Information about the Company or another company to others. You also may not suggest that anyone purchase or sell any company's securities while you are aware of Material Nonpublic Information about that company. These practices, known as "tipping," also violate U.S. and Australian securities laws and can result in the same civil and criminal penalties that apply if you engage in insider trading directly, even if you do not receive any money or derive any benefit from trades made by persons to whom you passed Material Nonpublic Information. This Policy against "tipping" applies to information about the Company and its securities, as well as to information about Company Counterparties. This Policy does not restrict legitimate business communications on a "need to know" basis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•It is against Company policy for you to engage in short-term or speculative transactions in Company securities. As such, you may not engage in: (a) short-term trading (generally defined as selling Company securities within six months following a purchase); (b) short sales (selling Company securities you do not own); (c) transactions involving publicly traded options or other derivatives, such as trading in puts or calls with respect to Company securities; and (d) hedging transactions. Additionally, because securities held in a margin account or pledged as collateral may be sold without your consent, if you fail to meet a margin call or if you default on a loan, a margin or foreclosure sale may result in unlawful insider trading. Because of this danger, you are prohibited from including Company securities in a margin account or pledging Company securities as collateral for a loan. The foregoing restrictions apply to all directors, officers, employees and consultants. These restrictions also apply to anyone that lives in your household. The SEC and federal prosecutors may presume that trading by family

members is based on information you supplied and may treat any such transactions as if you had traded yourself. There is no exception for small transactions or transactions that may seem necessary or justifiable for independent reasons, such as the need to raise money for an emergency expenditure.

For purposes of this Policy, references to "trading" and "transactions" includes, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•purchases and sales of Company securities in public markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•sales of Company securities obtained through the exercise of employee stock options granted by the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•making gifts of Company securities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•using Company securities to secure a loan.

For the purposes of this Policy, a "**Trading Day**" shall mean any day on which the Nasdaq is open for trading.

For the purposes of this Policy, the Company's "securities" include both common stock (listed on Nasdaq) and CHESS Depositary Interests (CDIs) (listed on ASX).

Directors, officers, employees and consultants should consult the Office of the Corporate Secretary if they have any questions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.** **What is "Material Nonpublic Information"?**

1.*Material Information*

Material information generally means information that a reasonable investor would consider important in making an investment decision to buy, hold, or sell securities or would likely to have a material effect on the price or value of those securities. Either positive or negative information may be material. Depending on the circumstances, common examples of information that may be material include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•earnings, revenue, or similar financial information;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•technical or scientific information relating to our operations, project, or research and development activities;

• unexpected financial results;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•unpublished financial reports or projections;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•extraordinary borrowing or liquidity problems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•changes in control or sale of all or part of the Company's business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•changes in directors, senior management, or auditors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•information about current, proposed, or contemplated transactions, business plans, financial restructurings, acquisition targets or significant expansions or contractions of operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•changes in dividend policies or the declaration of a stock split or the proposed or contemplated issuance, redemption, or repurchase of securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•negotiations regarding an important license, distribution agreement, joint venture or collaboration agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•material defaults under agreements or actions by creditors, clients, or suppliers relating to a company's credit rating;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•information about major contracts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•impending financial problems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the interruption of project development or production or other aspects of a company's business as a result of an accident, fire, natural disaster, or breakdown of labor negotiations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•major environmental incidents or environmental regulatory issues;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•institution of, or developments in, major litigation, investigations, or regulatory actions or proceedings; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•information about Company affiliates.

Federal, Nasdaq, ASIC, and ASX investigators will scrutinize a questionable trade after the fact with the benefit of hindsight, so you should always err on the side of deciding that the information is material and not trade. If you have questions regarding specific transactions, please contact the Office of the Corporate Secretary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.*Nonpublic Information*

Nonpublic information is information that is not generally known or available to the public.

We consider information to be available to the public only when:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•it has been released to the public by the Company through appropriate channels (e.g., by means of a press release, a filed Form 8-K with the SEC or a widely disseminated statement from a senior officer); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•enough time has elapsed to permit the investment market to absorb and evaluate the information. As a general rule, you should consider information to be nonpublic until two full Trading Days have lapsed following public disclosure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.** **Unauthorized Disclosure**

All directors, officers, employees and consultants must maintain the confidentiality of Company information for competitive, security and other business reasons, as well as to comply with applicable securities laws. All information you learn about the Company or its business plans is potentially nonpublic information until it is publicly disclosed. You should treat this information as confidential and proprietary to the Company. You may not disclose it to others, such as family members, other relatives, or business or social acquaintances.

Also, legal rules govern the timing and nature of our disclosure of material information to outsiders or the public. Violation of these rules could result in substantial liability for you, the Company and its management. For this reason, we permit only specifically designated representatives of the Company to discuss the Company with the news media, securities analysts and investors. If you receive inquiries of this nature, refer them to the Chief Financial Officer ("**CFO**") or the Office of the Corporate Secretary. At any time when the Company does not have an active CFO, the duties and responsibilities assigned to the CFO under this Policy shall be performed by the chief executive officer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.** **When and How to Trade Company Stock**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.*Overview*

Directors, officers and certain other employees and consultants who are so designated from time to time (such officers and designated employees and consultants, "**Restricted Employees**")

are for purposes of this Policy required to comply with the restrictions covered below. Even if you are not a director or a Restricted Employee, however, following the procedures listed below may assist you in complying with this Policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.*Blackout Periods*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a.** **Regular Blackout Periods**

------

The Company's executive officers and directors and all other employees, and family members of all of the above who share their households may only trade the Company's securities during the period commencing two full Trading Days following a release of quarterly results, and ending on the date that is ten Trading Days prior to the end of the subsequent quarter. Nonetheless, as mentioned above, no trade of the Company's securities may be made during these periods if the person covered by this Policy possesses Material Nonpublic Information which has not be disseminated in the public market for at least two full Trading Days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b.** **Special Blackout Periods**

From time to time due to certain developments relating to Material Nonpublic Information, the Company may implement special blackout periods during which the Company may notify particular individuals that they should not engage in any transactions involving the purchase or sale of Company securities or the securities of another company. If you are subject to a special blackout period, you should not trade in the applicable company's securities during such time and you should not disclose to others the fact that you are prohibited from trading. In exceptional circumstances, the CFO may give written clearance to sell Company securities to individuals subject to blackout period restrictions. A request seeking such clearance must be made in writing to the CFO and must include an undertaking that the individual is not in possession of Material Nonpublic Information and must also specify severe financial or other unique hardships that would result in the absence of such clearance. The CFO shall have discretion to deny any such request and clearance shall not be granted if, upon consideration of an individual's specific circumstances, the CFO determines that there is a reasonable likelihood that the individual is in possession of Material Nonpublic Information.

# However, it is not the Company's policy to impose special blackout periods every time that Material Nonpublic Information exists, or every time that a Company employee may be in the possession of Material Nonpublic Information. Thus, the absence of a special blackout should not be interpreted as permission to trade. In addition, if you are subject to the Company's pre-clearance policy (described below), you must pre-clear transactions even if you initiate them while a special blackout period is not in place.
Even if a special blackout period is in place, you may exercise Company stock options if no shares are to be sold – you may not, however, effect sales of stock issued upon the exercise of stock options (including same-day sales and cashless exercises). Generally, all pending purchase and sale orders regarding Company securities that could be executed while a special blackout period is not in place must be cancelled before a special blackout period is implemented so as to avoid any purchases and sales during such period.

In light of these restrictions, if you expect a need to sell Company stock at a specific time in the future, you may wish to consider entering into a prearranged Rule 10b5-1(c) trading plan, as discussed below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.*Pre-clearance*

The Company requires its directors and Restricted Employees to contact the Office of the Corporate Secretary in advance of effecting any purchase, sale or other trading of Company securities and to obtain prior approval of the transaction, other than transactions made under an approved Rule 10b5-1 Trading Plan pursuant to Section II.E below. **The pre-clearance policy applies to directors and Restricted Employees even if they are initiating a transaction while a special blackout period is not in place.** The pre-clearance policy also applies to anyone that lives in the household of a director or Restricted Employee.

If a transaction is approved under the pre-clearance policy, the transaction must be executed by the end of the second full Trading Day after the approval is obtained, but regardless may not be executed if you acquire Material Nonpublic Information concerning the Company during that time. If a transaction is not completed within the period described above, the transaction must be approved again before it may be executed.

If a proposed transaction is not approved under the pre-clearance policy, you may not transact in Company stock, and you should not inform anyone within or outside of the Company of the restriction. Any transaction under a Rule 10b5-1 trading plan (discussed below) will not require pre-clearance at the time of the transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E.** **Rule 10b5-1 Trading Plans**

Rule 10b5-1 provides a defense from insider trading liability under United States federal and state securities laws if trades occur pursuant to a pre-arranged trading plan that meets specified conditions. It is possible to pre-arrange trades in Company securities by entering into a written trading plan. Trading plans can be established for a single trade or a series of trades. A plan must either specify the number of securities to be bought or sold, along with the price and the date, or provide a

written formula for determining this information. Alternatively, a trading plan can delegate investment discretion to a third party, such as a broker, who then makes trading decisions without further input from the person implementing the plan. Because the SEC rules on trading plans are complex and have been recently revised, you should consult with your broker and the Company and be sure you fully understand the limitations and conditions of the rules before you establish a trading plan.

All Rule 10b5-1 trading plans must be reviewed and approved in advance by the Office of the Corporate Secretary.

A Rule 10b5-1 trading plan may not operate as a defense to insider trading liability under Australian securities laws, and you should ensure that you comply with those laws at all times.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**F.** **Noncompliance**

Anyone who fails to comply with this Policy will be subject to appropriate disciplinary action, up to and including termination of employment.

*Questions about these guidelines should be directed to the Office of the Corporate Secretary.*
