PART I

Overview

MP Materials Corp., including its subsidiaries (the “Company,” “MP Materials,” “we,” “our,” and “us”), is the largest producer of rare earth materials in the Western Hemisphere. Headquartered in Las Vegas, Nevada, the Company owns and operates the Mountain Pass Rare Earth Mine and Processing Facility (“Mountain Pass”) located near Mountain Pass, San Bernardino County, California, the only rare earth mining and processing site of scale in North America. The Company is also developing a rare earth metal, alloy and magnet manufacturing facility in Fort Worth, Texas (“Independence” or the “Independence Facility”). The Company’s operations are organized into two reportable segments: Materials and Magnetics. See Note 20, “Segment Reporting,” in the notes to the Consolidated Financial Statements for additional information.

The Materials segment operates Mountain Pass, which produces refined rare earth oxides and related products as well as rare earth concentrate products. The Materials segment primarily generates revenue from (i) sales of rare earth concentrate, which is principally sold pursuant to the Offtake Agreements (as defined in Note 19, “Related-Party Transactions,” in the notes to the Consolidated Financial Statements) to Shenghe (as defined in the “Customers” section below), that, in turn, typically sells that product to refiners in China, and (ii) sales of separated rare earth products, including neodymium-praseodymium (“NdPr”) oxide, primarily to customers in Japan, South Korea, and broader Asia.

The Magnetics segment operates the Independence Facility, where the Company began production of magnetic precursor products in December 2024 and anticipates manufacturing neodymium-iron-boron (“NdFeB”) permanent magnets by the end of 2025. The Company expects that the Magnetics segment will begin generating revenue from sales of magnetic precursor products, specifically NdPr metal, to a single customer in the U.S. in the first quarter of 2025.

Certain rare earth elements (“REE”) serve as critical inputs for the rare earth magnets inside the electric motors and generators powering carbon-reducing technologies such as hybrid and electric vehicles (referred to collectively as “xEVs”) and wind turbines, as well as drones, defense systems, robotics and many other high-growth, advanced technologies. Our integrated operations at Mountain Pass combine low production costs with high environmental standards, thereby restoring American leadership to a critical industry with a strong commitment to sustainability. The Company believes businesses are increasingly prioritizing diversification and security of their global supply chains to reduce reliance on a single producer or region for critical materials. As the only scaled source in North America for critical rare earths, with a processing footprint designed to operate with best-in-class sustainability and an industry-leading cost structure, the Company believes it is well-positioned to thrive as the global economy electrifies and as the United States prioritizes domestic manufacturing and secure supply chains.

The Company’s mission is to maximize stockholder returns over the long-term by executing a disciplined business strategy to restore the full rare earth magnetics supply chain to the United States of America. The Company believes it will generate positive outcomes for U.S. national security and industry, the U.S. workforce, and the environment.

Rare Earth Industry Overview

REE are crucial enablers of modern technologies spanning transportation, electronics, and robotics that have permeated modern society. REE are used in supporting, but often critical, amounts in hundreds of different technologies, materials, and chemicals worldwide for commercial, industrial, social, medical, and environmental applications. In the last several decades, REE have become deeply integrated into the foundation of modern technology and industry and have proven to be difficult to duplicate or replace.

By economic value, neodymium-praseodymium (previously defined as “NdPr,” also referred to as “PrNd” or “didymium”) is the largest segment of the REE market. NdPr is primarily used in neodymium-iron-boron (“NdFeB”) permanent magnets for electric machines such as EV traction motors, wind power generators, drones, robotics, electronics and a growing list of other applications. The rapid growth of these and other end-use markets is expected to drive substantial demand growth for NdPr and NdFeB magnets in the years ahead.

The REE group includes 17 elements, primarily the 15 lanthanide elements. Lanthanum, cerium, praseodymium, neodymium and promethium are considered “light” REE (“LREE”); samarium, europium and gadolinium are often referred to as “medium” REE; while terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium are considered “heavy” REE (“HREE”). Two additional elements, yttrium and scandium, are often classified as HREE although they are not lanthanides. Depending upon the rare earth-bearing mineral, the relative abundance of light, medium and heavy REE will differ. The REE in the Mountain Pass ore body are contained primarily within bastnaesite and related minerals in which LREE are predominant.

The aggregate global market for rare earth oxides (“REO”) totaled approximately 226,000 metric tons (“MTs”) in 2024 and is expected to grow at a compound annual growth rate (“CAGR”) of approximately 5.9% through 2040, according to research by Adamas Intelligence Inc. (“Adamas”). Further, Adamas estimates that the NdPr segment of the REO market, which makes up a significant majority of the market value, is expected to grow at an 8.4% CAGR through 2040 (excluding the impact of swarf recycling), well in excess of the overall REO market. This expected growth will be driven by secular growth in demand for NdPr magnets.

Rare earth materials are used in a diverse array of end markets, including:

• Electric Mobility:** traction motors in passenger xEVs, commercial xEVs, special purpose vehicles, two-wheelers, and other applications;

*•*Industrial, Consumer and Professional Service Robotics: motors, actuators, brakes and sensors used in industrial robots and welders, as well as consumer, service and humanoid robots;

• Renewable Power Generation:** wind power generators, for on- and offshore applications;

• Energy-Efficient Motors, Pumps and Compressors:** heating, ventilation and air conditioning (“HVAC”) systems, elevators, escalators, consumer appliances and other industrial applications;

*•*Consumer and Medical Applications: smart phones, tablets, laptops, hard disk drives, audio speakers, microphones, cameras, printers, cordless power tools as well as fiber optics, laser crystals, x-ray equipment, prostheses, dental crowns and more;

• Critical Defense Systems:** guidance and control systems, communications, avionics, global positioning systems, radar and sonar, drones, thermal barrier coatings and firearms; and

• Catalysts and Phosphors:** catalysts for vehicle emissions reduction and fuel refining, as well as phosphors for energy-efficient lighting, backlighting and counterfeit currency detection.

Process

The Company has established a three-stage business plan to enable and scale the full rare earth supply chain. Processing of rare earth materials at Mountain Pass includes five primary process steps: (i) mining and crushing; (ii) milling and flotation; (iii) roasting, leaching and impurity removal; (iv) separation and extraction; and (v) product finishing. Through its upstream operations (“Stage I”), which are comprised of the first two of these process steps, the Company produces rare earth concentrate that is marketed to refiners primarily via a distribution arrangement. In 2023, the Company commenced midstream operations (“Stage II”), which consist of the latter three primary process steps to produce separated rare earth products that are marketed directly to end users and indirectly via distributors, with revenue generated primarily from the magnet supply chain. Lastly, the Company is establishing downstream capabilities (“Stage III”) at Independence to convert a portion of the REO produced at Mountain Pass into rare earth magnets and its precursor products to be marketed directly to end users. The Company’s Materials segment includes both upstream and midstream operations, while the downstream operations constitute the Magnetics segment.

Upstream Operations - Stage I

Following the acquisition of Mountain Pass in July 2017, the Company began implementing Stage I, which was designed to re-establish stable and scaled production of rare earth concentrate by leveraging the site’s existing processing facilities. The upstream operations include the mining of primarily bastnaesite ore followed by comminution, which involves crushing and grinding the ore into a milled slurry. Then, the slurry is processed by froth flotation, whereby the bastnaesite is carried to the surface while the gangue, or non-desired, elements are suppressed and disposed as tailings.

Since restarting operations from cold-idle status, the Company implemented changes in the milling, flotation and tailings management processes; implemented and continue to advance an improved reagent scheme to enhance mineral recovery; and implemented operational best practices. Together, these changes have materially increased plant uptime and reliability driving enhanced flotation throughput, REO recovery and production as well as tailings facility reliability and throughput at a lower cost per processed ton. Following the implementation of the Company’s Stage I optimization plan, the Company has achieved at least 40,000 MTs of annual REO Production Volume (as defined in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations) since 2021. The Company’s Stage I optimization plan enabled it to achieve what the Company believes to be world-class production cost levels for rare earth concentrate.

In November 2023, the Company announced its “Upstream 60K” strategy whereby the Company intends to grow its annual REO Production Volume to approximately 60,000 MTs by expanding upstream capacity via investments in further

beneficiation, including the ability to process alternative feedstocks and upgrade lower-grade feedstocks. The Company aims to achieve this initiative within the next three years with modest incremental capital investment.

Midstream Operations - Stage II

Stage II advanced the Company’s operations from the production of rare earth concentrate to the separation of individual REE. The project incorporated upgrades and enhancements to the prior facility process flow intended to reliably produce separated REE at a low cost while minimizing the impact on the environment. More specifically, the Company reintroduced an oxidizing roasting circuit, reoriented portions of the plant process flow, increased product finishing capacity, improved wastewater management, and made other improvements to materials handling and storage.

The roasting step that oxidizes the rare earth concentrate in a rotary kiln is crucial to ensuring cost-competitiveness. One of the unique attributes of bastnaesite ore is the ability to convert the trivalent cerium in the mixed rare earth concentrate to tetravalent cerium that has a low propensity to dissolve, enabling cerium to be removed expediently along with other insoluble gangue elements without selective extraction. Removal of the lower-value cerium early in the Company’s separations process allows for a significant reduction in the mass of material to be separated and finished, thus reducing the energy, reagents, and wastewater required to produce the higher-value NdPr. Additionally, roasting facilitates a lower temperature leach that reduces maintenance costs and downtime.

During the second half of 2023, the Company began producing separated rare earth products. However, the Company continues to expect that it may take many quarters to achieve its designed throughput of separated products. As the Company increases production of separated products over time, it expects to improve the Company’s per-unit production costs of NdPr oxide, which represents a majority of the value contained in the Company’s concentrate. Additionally, beginning in the fourth quarter of 2023, the Company utilizes tolling partners in Southeast Asia to process the Company’s NdPr oxide into NdPr metal for delivery to the Company’s customers globally.

In February 2022, the Company was awarded a $35.0 million contract by the Department of Defense’s Office of Industrial Base Policy, Industrial Base Analysis and Sustainment program, to design and build a facility to process HREE. Successful completion of this project will establish, for the first time in many years, commercial-scale processing and separation of HREE in support of commercial and defense applications in the U.S. The HREE processing and separations facility (the “HREE Facility”) will be built at Mountain Pass and will be integrated into the rest of the Company’s facilities. The Company is currently advancing the facilitating works, engineering and procurement for the HREE Facility, which is expected to produce HREE products primarily for use in the Magnetics segment.

Downstream Operations and Future Capabilities - Stage III

In February 2022, the Company commenced construction of the Independence Facility, the U.S.’s first fully-integrated rare earth metal, alloy and magnet manufacturing facility located in Fort Worth, Texas. Independence will convert NdPr oxide produced at Mountain Pass into permanent magnets and its precursor products, while incorporating magnet recycling capabilities. The Company expects Independence to be capable of producing approximately 1,000 MTs of finished rare earth magnets per year at its initial design capacity, with infrastructure to support future capacity expansion. The initial capacity would be sufficient to power more than 700,000 electric vehicle motors annually, in addition to enabling other key markets including robotics, semiconductor manufacturing, clean energy, electronics and defense technologies. The Independence Facility serves as the business and engineering headquarters for the Company’s Magnetics segment.

In December 2024, the Company commissioned its electrowinning capability to produce NdPr metal from NdPr oxide at Independence. Further, the Company introduced capabilities to produce neodymium-praseodymium-iron-boron alloy flake, a key precursor product that is utilized as the material feedstock for magnet manufacturing. In addition, the Company recently began trial production of automotive-grade, sintered NdFeB magnets at its new product introduction (“NPI”) facility within Independence. In the near-term, the Company expects to produce and sell magnetic precursor products ahead of commissioning of its magnet manufacturing capabilities, which are targeted to enter service at the end of 2025. Following commissioning of these capabilities and qualification of the Company’s finished magnets, the Company expects it will manufacture and sell finished magnets.

In March 2024, the Company was awarded a $58.5 million Section 48C Qualifying Advanced Energy Project Tax Credit (the “48C Credit”) to advance the construction of the Independence Facility. The 48C Credit is an investment tax credit equal to 30% of qualified investments for certified projects that meet prevailing wage and apprenticeship requirements and are placed in service after the date of the award. The allocation of the awards under the 48C Credit was issued by the Internal Revenue Service and Treasury following a competitive, oversubscribed process administered by the Department of Energy that evaluated the technical and commercial viability and environmental and community impact of approximately 250 projects.

Strategy

Offer the Western Hemisphere a trusted, sustainable source of supply for materials and components that enable the development of critical industries.

More than 60 years of operations at Mountain Pass have demonstrated that the Company’s ore body is one of the world’s largest and highest-grade rare earth resources. The low-volume nature of rare earth mining coupled with the exceptional scale and quality of the ore body results in a resource with significant viability well into the future.

Upon achieving our designed throughput of separated products, the Company believes Mountain Pass will be one of the largest, most advanced and efficient fully-integrated REO processing facilities in the world, and the only such facility located in the Western Hemisphere. The Company aims to provide users of rare earths a U.S. alternative that helps avoid the risks associated with the single point-of-failure that Chinese producers represent. In addition, the U.S. government is actively seeking to end the country’s reliance on foreign REE sources, and the Company believes that this provides it with an advantage relative to non-U.S. REE producers.

The global effort to curb carbon emissions and address climate change often focuses on the impact of the transportation system. The Company believes that its products will play a large role in advancing those efforts. To date, nearly all U.S. states and the District of Columbia have mandated or offer incentives to support deployment of xEVs or alternative fuel vehicles and supporting infrastructure, either through state legislation or private utility incentives within the state, with similar mandates and incentives in other countries globally. Additionally, in August 2022, the U.S. government enacted the Inflation Reduction Act of 2022, which, among other things, provides several tax incentives to promote clean energy adoption, including tax credits on the purchase of xEVs and the production of certain critical minerals such as NdPr oxide. The NdPr oxide that the Company produces at Mountain Pass is essential to the permanent magnet motor technology deployed in a significant majority of current xEVs.

In addition, the Company believes end consumers will demand that the materials used to build these vehicles be extracted sustainably. MP Materials is committed to environmental responsibility and sustainability. The Company’s environmental management plans cover biodiversity impacts, waste and noise management, air and water pollution, water extraction and discharge, as well as natural resource disturbance and toxic chemical usage. The Company believes this commitment to responsible production of REO is a strong competitive advantage.

A confluence of geopolitical and economic factors is causing downstream customers, such as automotive and industrial original equipment manufacturers (“OEMs”), to be increasingly focused on supply risk, highlighting the need to develop domestic production of REE and related products. As the demand for xEVs and robotics continues to grow, the Company anticipates that automotive and industrial OEMs will continue to reconfigure their supply chains to secure a consistent and reliable supply of rare earth materials for manufacturing critical magnetic components. MP Materials is strategically positioned to leverage this opportunity by collaborating with both existing and prospective customers. Our goal is to support their efforts in realigning capital and labor within their supply chains to accommodate the growing demand for electrification.

Leverage the Company’s low-cost position to maximize earnings power in all commodity price environments.

The success of the Company’s business reflects its ability to manage its costs. The Company’s production achievements in Stage I have provided economies of scale to lower production costs per unit of REO produced in concentrate. Furthermore, Stage II was designed to enable the Company to continue to manage its cost structure for separating REE through an optimized facility process flow. This process flow allows the Company to use less energy and raw materials per ton of separated REO. Despite the initial phase of NdPr oxide production leading to elevated per-unit costs, the Company anticipates a decrease in per-unit production costs over time as production volumes expand.

Optimization of logistics is also central to maintaining a low-cost position relative to other global producers. Mountain Pass, located immediately adjacent to Interstate 15 and within a one-hour drive of a major railhead and a four-hour drive of the Ports of Los Angeles and Long Beach, offers transportation advantages that create meaningful cost efficiencies in securing incoming supplies and shipping its final products. The Company believes the self-contained nature of its operations, with mining, milling, separations, and finishing all on one site, creates additional cost advantages and operational risk mitigation. In addition, The Mountain Pass site includes a currently idle chlor-alkali facility that may be restarted in the future to produce key raw materials used in separations. Upon achieving the designed throughput of separated products, the Company’s integrated site will incur lower costs of packaging, handling and transportation as compared to competitors who lack co-located processing.

Further the Company’s mission and ability to capture the full rare earth value chain through downstream integration into rare earth magnet production.

At Independence, with GM as a foundational customer, the Company is pursuing vertical integration through further downstream processing of REO into finished rare earth magnets and precursor products, and incorporating process waste and end-of-life magnet recycling. As discussed above, in December 2024, the Company commissioned its electrowinning capability to produce NdPr metal from NdPr oxide and introduced capabilities to produce neodymium-praseodymium-iron-boron alloy flake, a key precursor product that is utilized as the material feedstock for magnet manufacturing. In addition, the Company recently began trial production of automotive-grade, sintered NdFeB magnets at its NPI facility within Independence. The Company is targeting the commissioning of its magnet manufacturing capabilities by the end of 2025.

Throughout 2024, the Company significantly advanced the organization’s engineering and manufacturing technology capabilities and meaningfully added to its magnetics team of scientists, technicians, and engineers, with the team now comprised of over 100 employees. With the recent achievements at Independence, the Company has taken a significant step towards reestablishing a fully integrated, domestic supply chain for these critical components for the first time in decades. By offering magnet customers a complete, end-to-end Western supply chain solution, the Company believes vertical integration represents a material incremental value creation opportunity, which the Company is uniquely positioned to provide given its ownership of Mountain Pass.

Beyond re-establishing a supply chain for REE in the Western Hemisphere, the Company expects to capitalize on the growing demand for downstream magnetic materials. In aiming to achieve technical and cost leadership, the Company expects it will continue to explore opportunities to invest in, develop, and/or sponsor new downstream initiatives for REO and rare earth products that support industrial electrification. MP Materials’ successes at Mountain Pass highlight its ability to identify undervalued assets, execute disciplined strategies, and assemble skilled management. The Company will leverage its expertise across the critical minerals value chain, responsibly allocating capital to benefit stockholders and align with its mission.

The health, safety, and well-being of the Company’s employees, suppliers and communities are a priority, with “Safety” being one of the Company’s six core values, along with “Empowerment,” “Entrepreneurship,” “Integrity,” “Results,” and “Unwavering” effort. MP Materials is committed to maintaining a strong safety culture and continues to emphasize the importance of its employees’ role in identifying, mitigating and communicating safety risks. To ensure the ongoing safety of employees and any contractors working on-site, the Company has a clear set of health and safety guidelines in place and routinely conducts general as well as equipment- and process-specific safety training. The Company believes that the achievement of superior safety performance is both an important short-term and long-term strategic imperative in managing its operations.

All newly-hired employees at Mountain Pass complete a minimum of 24 hours of Federal Mine Safety and Health Administration (“MSHA”) training during the onboarding process and must, at a minimum, complete annual refresher training. Following their initial training, depending on their job classification, new employees complete targeted online and supervised field training specific to their roles and responsibilities. For example, operations and maintenance workers go through specific Lock Out/Tag Out/Try Out training, confined-space work and rescue, and forklift classroom and in-the-field training. In total, during 2024, the Company’s employees completed over 13,000 hours of new hire and/or annual refresher training and over 1,200 hours of emergency medical response training, including first aid and CPR.

The Company utilizes a formalized digital data reporting system to track all incidents reportable to the California Occupational Health and Safety Administration and MSHA. The Company tracks lost time injuries, recordable injuries, recordable injury rates, and near-miss reports. MP Materials strongly encourages the reporting of near-miss incidents so that it can mitigate hazards or change procedures to improve workforce safety in advance of any actual incident. As of December 31, 2024, the Company had completed over 1,700 days without a lost-time injury.

Diversity and Meritocracy

MP Materials believes that a diverse and meritocratic workforce and Board of Directors produces better overall decision-making for employees, which benefits the organization. In prioritizing hiring employees with the requisite skills, the Company continues to assemble a diverse workforce. As of December 31, 2024, based on employees’ self-reporting, veterans and women represented 4% and 15%, respectively, of the Company’s workforce and 20% of managerial or supervisory positions were occupied by women. As of December 31, 2024, women represented 28% of the Company’s Board of Directors. Additionally, as of December 31, 2024, 51% of the Company’s workforce was composed of underrepresented minorities.

Employee Engagement and Development

Employee engagement efforts are critical in ensuring all employees feel heard, respected, and valued, and that applicable actions are taken when feedback is received. The Company continues to hold events where collaboration occurs and contributions are recognized while continuing its focus on providing opportunities for employees to interact with executive management through events such as in-person sessions, milestone celebrations, and routine stand-up briefings.

Methodical execution is key to ensuring Company goals are achieved and exceeded. To ensure the Company’s employees receive the feedback they need to grow and thrive in their careers, MP Materials continually reviews and updates its performance-management processes. The Company ensures that new hires receive the feedback and support they need by scheduling periodic performance evaluations three to six months after their introductory periods. Managers hold reviews with all employees no less than annually to give them an opportunity to discuss work performance. This performance management process, rooted in the values of the organization, sets the foundation for applicable goal setting, individual development plans and career pathways going forward.

MP Materials is dedicated to the continual training and development of its employees, especially of those in field operations, to ensure the Company develops future managers and leaders from within its organization. The training starts on an employee’s first day with on-boarding procedures that focus on safety, responsibility, ethical conduct, and collaborative teamwork. In addition, the Company has partnered with educational institutions, governmental authorities, and strategic outside organizations to further enhance and improve access to the talent required to advance the Company’s mission. The Company also has an electrical and instrumentation apprenticeship program that pays for employees to attend trade school to increase their opportunity for future advancement.

Sustainability and Natural Resources

The Company’s business provides a key input to carbon-reducing technologies critical for the transition to a low-carbon economy. Further, MP Materials is solving for the foreign-controlled overconcentration of the rare earth supply while helping to enable a more sustainable future. Sustainability at MP Materials means much more than maintaining environmentally conscious operations; it means caring for the health, safety, and well-being of our employees; encouraging a spirit of joint ownership, entrepreneurship, and continuous growth; supporting the communities that surround us; and operating with integrity. The Company recognizes that it has a responsibility to operate as efficiently as possible to reduce emissions.

The Company believes Mountain Pass is the world’s cleanest and most environmentally sustainable rare earth production facility. Producing rare earth materials requires significant energy and resources and can lead to environmental challenges if not carefully managed. MP Materials understands that our natural resources, such as water, are precious and limited. As such, the Company is committed to limiting resource consumption, increasing efficiency, and achieving as light of an environmental

footprint as possible. The Company does this, in part, by investing in water recycling, reducing reagent usage, implementing energy reduction initiatives, and utilizing a dry stack tailings process.

The Company believes it is unique among scaled rare earth producers in its use of a dry tailings process that allows recycling of the water used in the milling and flotation circuit and eliminates the need for high-risk wet tailings ponds and traditional impoundment dams. The Company’s tailings and concentrate dewatering methods provide a closed-loop water resource for its beneficiation process satisfying approximately 95% of those processes’ water needs at Mountain Pass. The Company also has a variety of initiatives underway at Mountain Pass to limit freshwater withdrawal and maximize recycling. In addition, the Company remains focused on ensuring the most efficient use of energy to minimize hydrocarbon consumption and greenhouse gas (“GHG”) emissions.

The materials that the Company produces are essential to the supply chains for many technologies that help decarbonize the global economy, improve productivity in the workforce, and better the lives of many. Without MP Materials’ conscientiously-mined materials, not only will the future of magnetic technologies depend on more highly polluting traditional production methods, but the advanced research and development related to these vital applications and their manufacturing will continue to follow that supply overseas. MP Materials is restoring the resource independence of the U.S.— removing the single point-of-failure in the supply chain for these products and ensuring that American industry can determine its own future in the automotive, robotics, aerospace, renewable energy, and information technology industries.

Customers

Materials Segment

Currently, the Company sells the vast majority of its rare earth concentrate to Shenghe Resources (Singapore) International Trading Pte. Ltd. (“Shenghe”) under the terms of the 2024 Offtake Agreement, which became effective in January 2024 and replaced and extended the 2022 Offtake Agreement (as such terms are defined in Note 19, “Related-Party Transactions,” in the notes to the Consolidated Financial Statements). Shenghe is an indirect majority-owned subsidiary of Shenghe Resources Holding Co., Ltd., a leading global rare earth company listed on the Shanghai Stock Exchange. Under the 2024 Offtake Agreement, Shenghe is contractually obligated to purchase the Company’s rare earth concentrate product meeting certain minimum specifications as the exclusive distributor in China on a “take-or-pay” basis (such that they are obliged to pay for product even if they are unable or unwilling to take delivery), with certain exceptions for the Company’s direct sales globally. Shenghe then sells the rare earth concentrate it acquires to customers in China for processing into refined products. In addition, at the discretion of the Company, Shenghe may be required to purchase on a “take-or-pay” basis certain non-concentrate rare earth products, although the Company may sell all non-concentrate rare earth products in its sole discretion to customers or end users in any jurisdiction.

The initial term of the 2024 Offtake Agreement is two years, with the option for the Company to extend the term for an additional one-year period. The terms of the 2024 Offtake Agreement are substantially the same as those of the 2022 Offtake Agreement with the exception of the addition of NdPr metal into the definition of non-concentrate rare earth products.

In February 2023, the Company entered into a distributorship agreement (the “Distribution Agreement”) with Sumitomo Corporation of Americas (“Sumitomo”), under which Sumitomo serves as the exclusive distributor of the NdPr oxide and NdPr metal produced by the Company to Japanese customers. The initial term of the Distribution Agreement extends through the end of 2025 with options to renew annually.

The Company also regularly enters into short- and long-term sales contracts with other customers for the sale of its rare earth concentrate and separated rare earth products.

Magnetics Segment

In April 2022, as discussed above, the Company entered into a long-term agreement to supply magnets and precursor products manufactured at the Independence Facility to GM as its foundational customer. The Company is also pursuing sales opportunities to other customers for its future magnet products.

Suppliers

The Materials segment uses certain proprietary chemical reagents in its flotation process, which it currently purchases from third-party suppliers. The hydrometallurgy, separations, and product finishing processes are reliant upon certain commodity reagents. These chemicals are subject to pricing volatility, supply availability and other restrictions and guidelines. In the event of a supply disruption or any other restriction, the Company believes that alternative reagents could be sourced for certain

processes. As operations scale at the Independence Facility, the Company expects that the Magnetics segment will be supplied with NdPr oxide produced at Mountain Pass, which is within the Materials segment. In addition, certain raw materials expected to be used in the production of metal and magnets may be subject to pricing volatility, supply availability and other restrictions and guidelines.

Patents, Trademarks and Licenses

The Company relies on a combination of trade secret protection, nondisclosure and licensing agreements, patents and trademarks to establish and protect its proprietary intellectual property rights. The Company utilizes patents, trade secret protection and nondisclosure agreements to protect its proprietary rare earth technology.

Competition

The rare earth mining, processing, and magnetics manufacturing markets are capital-intensive and highly competitive. With continued state-sponsored consolidation, there remain two major rare earth groups in China. These groups and their affiliates control (and/or allocate to unaffiliated third parties) substantially all of China’s quota for concentrate production and rare earth refining. Outside of China, there are few producers operating at scale, with processing capabilities located in Australia and Malaysia. China also maintains a dominant position in the supply of NdFeB permanent magnets due to its vast rare earth reserves, advanced processing capabilities, and vertically integrated production infrastructure.

Environmental and Regulatory Matters

The Company is subject to numerous federal, state and local environmental laws, certifications, regulations, permits, and other legal requirements applicable to the mining, mineral processing industry, and magnetics manufacturing industries including, without limitation, those pertaining to employee health and safety, air quality standards and emissions, water usage, wastewater and stormwater discharges, GHG emissions, hazardous and radioactive and other waste management, storage and handling of naturally occurring radioactive material, plant and wildlife protection, remediation of contamination, land use, reclamation and restoration of properties, procurement of certain materials used in the Company’s operations, groundwater quality and the use of explosives. Environmental laws and regulations continue to evolve which may require the Company to meet stricter standards and give rise to greater enforcement, result in increased fines and penalties for non-compliance, and result in a heightened degree of responsibility for companies and their officers, directors and employees. Future laws, regulations, permits or legal requirements, as well as the re-interpretation or change in enforcement of existing requirements, may require substantial increases in capital or operating costs to achieve and maintain compliance or otherwise delay, limit or prohibit operations, or impose other restrictions upon the Company’s current 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. The Company expects to continue to incur significant sums for ongoing environmental matters, including salaries, and expenditures for monitoring, compliance, remediation, reporting, pollution control equipment and permitting.

Risk Factor Summary

Our business is subject to a number of risks and uncertainties, including those highlighted immediately following this summary. Some of these risks are:

• We may be adversely affected by fluctuations in demand for, and prices of, REE and magnet materials.

• The success of our business will depend, in part, on the growth of existing and emerging uses for rare earth products.

• An increase in the global supply of rare earth products, dumping, predatory pricing and other tactics designed to inhibit our further downstream integration by our competitors may materially adversely affect our profitability.

• We operate in a highly competitive industry.

• Industry consolidation may result in increased competition, which could result in a reduction in revenue.

• Our ability to generate revenue will be diminished if we are unable to compete with substitutions for our rare earth materials.

• We currently rely on Shenghe to purchase the vast majority of our rare earth concentrate product on a “take-or-pay” basis and sell that product to end users in China; we cannot assure you that they will continue to honor their contractual obligations to purchase and sell our products, or that they will make optimum efforts to market and sell our products.

• Significant political, trade, regulatory developments, and other circumstances beyond our control, could have a material adverse effect on our financial condition or results of operations.

• Changes in China’s political environment and policies, including changes in export policy or the interpretation of China’s export policy and policy on rare earths production or the import of rare earth feedstock, may adversely affect our financial condition and results of operations.

• The production of rare earth products is a capital-intensive business that requires the commitment of substantial resources; if we do not have sufficient resources to provide for such production, it could have a material adverse effect on our financial condition or results of operations.

• Our continued growth depends on our ability to reach anticipated production rates for the separation of REE as part of the Stage II project at Mountain Pass, our only rare earth mining and processing facility.

• The production of magnets and magnetic precursor products in Stage III is dependent upon our ability to complete the buildout of the Independence Facility; an unanticipated delay in the completion of the Independence Facility could have a material adverse effect on our ability to produce magnets.

• If we infringe, or are accused of infringing, the intellectual property rights of third parties, it may increase our costs or prevent us from being able to commercialize new products.

• We may not be able to adequately protect our intellectual property rights. If we fail to adequately enforce or defend our intellectual property rights, our business may be harmed.

• We may not be able to obtain additional patents and the legal protection afforded by any additional patents may not adequately protect our rights or permit us to gain or keep any competitive advantage.

• If we are unable to perform the obligations under our long-term supply agreement with GM, this could have a material adverse effect on our financial position and results of operations.

• We may not be able to convert current commercial discussions with customers for the sale of REO products into contracts, which may have a material adverse effect on our financial position and results of operations.

• We may not successfully establish or maintain collaborative, joint venture and licensing arrangements, which could adversely affect our ability to vertically integrate into further downstream processing of our REO.

• Outbreaks, epidemics or pandemics could have an adverse effect on our business.

• We are subject to a number of operational risks of our business, including power outages or shortages at Mountain Pass; increasing costs or limited access to raw materials; disruptions in transportation or other services; inability to process REO that meet individual customer specifications; access to water; uncertainty in our estimates of REO reserves; labor matters/labor relations; information technology and cybersecurity breaches; and/or sustainability matters.

• We are subject to regulatory and business risks associated with our investment in VREX Holdco Pte. Ltd. (“VREX Holdco”).

*•*The conditional conversion features of our Convertible Notes (as defined in Note 10, “Debt Obligations” in the notes to the Consolidated Financial Statements), if triggered, may adversely affect our financial condition and operating results.

• Conversion of our Convertible Notes may dilute the ownership interest of our stockholders or may otherwise depress the price of our common stock.

• Certain provisions in the indentures governing the Convertible Notes may delay or prevent an otherwise beneficial takeover attempt of us.

• Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our debt.

Risks Relating to our Business and Industry

We may be adversely affected by fluctuations in demand for, and prices of, REE and magnet materials.

Because our revenue is, and will be for the foreseeable future, from the sale of rare earth products, changes in demand for, and the market price of (including taxes and other tariffs and fees imposed upon) REE and magnet materials could significantly affect our profitability. Our financial results may be significantly adversely affected by declines in our realized prices for REE and magnet materials. For example, as a result of the decrease in the market price of NdPr oxide in 2024, our NdPr Realized Price per KG (as defined in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations) decreased from $70 for the year ended December 31, 2023, to $51 for the year ended December 31, 2024, which negatively impacted our results of operations and cash flows.

REE and magnet material prices may fluctuate and are affected by numerous factors beyond our control such as interest rates, exchange rates, taxes, inflation or deflation, fluctuation in the relative value of the U.S. dollar against foreign currencies on the world market, shipping and other transportation and logistics costs, global and regional supply and demand for rare earth minerals and products, potential industry trends, such as competitor consolidation or other integration methodologies, and the political and economic conditions of countries that produce and procure REE and magnet materials. A change in the U.S. federal administration introduces uncertainty as to shifts in policies, tariffs, taxes, regulations, and priorities, all of w

The Company’s information security program is managed by a dedicated Chief Technology Officer (“CTO”), who has over 25 years of professional experience within information technology roles, including 15 years of security consulting experience. The CTO leads the information technology department, which is responsible for enterprise-wide cybersecurity strategy, policy, standards, architecture, and processes. The Company’s Cybersecurity Incident Response Committee (the “CIRC”), which is comprised of the Company’s CTO, Chief Financial Officer, General Counsel, Senior Vice President of Financial Reporting and Technical Accounting, and Vice President of Internal Audit, meets periodically and more often, as needed, in the event cybersecurity incidents are identified.

As part of the Company’s overall risk assessment process, the enterprise risk management framework considers cybersecurity risk alongside other company risks. The Company’s internal audit department collaborates with the Company’s information technology department to gather insights for assessing, identifying and managing cybersecurity threat risks, their severity, and potential mitigations. The Company actively engages with key vendors, industry participants, and intelligence and law enforcement communities as part of its continuing efforts to evaluate and enhance the effectiveness of its information security policies and procedures. Additionally, the Company provides cybersecurity awareness training to its employees, incident response personnel, and senior management.

Furthermore, the Company’s vendor management program addresses cybersecurity risks associated with its use of third-party service providers including suppliers, software, and cloud-based service providers. The Company proactively evaluates the cybersecurity risk of a third party by utilizing a repository of risk assessments, external monitoring sources, threat intelligence during contracting, and vendor selection processes. Security issues are documented and tracked, and periodic monitoring of third parties is conducted to mitigate risk.

The Company’s CTO provides periodic reports to the Audit Committee of the Company’s Board of Directors, as well as the CIRC, as appropriate. These periodic reports include updates on the Company’s cyber risks and threats, the status of projects to strengthen its information security systems, assessments of the information security program, and the emerging threat landscape. The information security program is regularly evaluated by the CTO with the results of those reviews reported to the CIRC, the Audit Committee of the Company’s Board of Directors, and the Board of Directors, as appropriate.

Cybersecurity threats, including as a result of any previous cybersecurity incidents, have not materially affected nor are they reasonably likely to affect the Company, including its business strategy, results of operations or financial condition.

Mountain Pass

The Company owns and operates the Mountain Pass Rare Earth Mine and Processing Facility (previously defined as “Mountain Pass”), which is located on 2,232 fee simple acres of land, approximately 50 miles southwest of Las Vegas, Nevada, near Mountain Pass, San Bernardino County, California, at geographic coordinates 35°28’56”N latitude and 115°31’54”W longitude. Mountain Pass supports the Company’s Materials segment and includes an open-pit mine in the production stage, infrastructure supporting mining and processing operations, overburden and ore stockpiles, a crusher, a mill/flotation plant, hydrometallurgy facilities, separation plants, product finishing facilities, tailings processing and storage facilities, a water treatment plant, an idle chlor-alkali facility, and on-site evaporation ponds, as well as laboratory facilities to support product analysis and research and development activities, offices, maintenance shops, warehouses and support buildings. In 2023, the Company completed recommissioning activities on its previously idle separation facilities at Mountain Pass and completed construction of new assets, which are utilized to separate rare earth concentrate into other products, including NdPr oxide. The Mountain Pass facilities and infrastructure, the majority of which were constructed between 2012 and 2023, are in good operating condition and benefit from routine maintenance. The net carrying amount of property, plant and equipment (excluding mineral rights) used in the operation of Mountain Pass was approximately $621 million as of December 31, 2024.

Mountain Pass directly abuts Interstate 15 and may be accessed by existing hard-surface roads. Water at Mountain Pass is supplied through active water wells, pit dewatering, and process water recovery. MP Materials’ facilities at Mountain Pass are powered by a natural gas-powered CHP plant, which produces electricity and steam, minimizing reliance on the regional electric power grid.

As of December 31, 2024, approximately 1,128 acres of the 2,232 acres were in use (e.g., existing buildings, infrastructure or active disturbance). Portions of the fee lands, none of which are actively being mined or are currently anticipated to be mined for the purpose of recovering ore, are subject to mineral reservations in favor of the U.S. for some properties and the State of California for other properties. The specific minerals reserved on those parcels vary according to the type of land patent or conveyance document through which the land was acquired or conveyed. The Company also owns mining and mill site claims over a further 15,000 acres of adjacent land. The lands surrounding Mountain Pass are mostly public lands managed by the Bureau of Land Management and the National Park Service. In addition, MP Materials holds 525 unpatented lode and mineral mining claims and mill sites under the provisions of The Mining Law of 1872. These mining claims and mill sites provide land for mining, ancillary facilities, and expansion capacity around Mountain Pass.

Mountain Pass represents the largest commercial source of rare earth materials in the Western hemisphere. Molybdenum Corporation of America began REE mining operations at Mountain Pass in 1952. Mining, milling, and separation processes continued under Unocal Corporation, which purchased Molybdenum Corporation of America in 1977, until 1998. In 2005, ChevronTexaco Corporation acquired Unocal Corporation and then, in 2008, Molycorp Minerals, LLC acquired Mountain Pass from Chevron Mining Inc. Operations relating to mining, milling and separations resumed under Molycorp until they were placed into cold-idle status in mid-2015. In July 2017, the Company acquired Mountain Pass from the Molycorp estate.

The Company holds the necessary permits to operate Mountain Pass, including conditional use and minor use permits from San Bernardino County, California, and an associated environmental impact report, all of which were issued in 2004, which currently allow continued operation of Mountain Pass through 2042, though the Company expects to extend such permits to allow for continued operation through at least 2053. Since restarting operations at the facility in the fourth quarter of 2017, the Company’s activities initially focused on the milling and flotation processes, leading to production of a bastnaesite concentrate, rich in REE, with the first concentrate sales in the first quarter of 2018. In the second half of 2023, the Company commenced production of separated rare earth products.

The bastnaesite ore body at Mountain Pass has been mined as a principal source of REE for a period of over 60 years. The Mountain Pass REE deposit is located within an uplifted block of Precambrian metamorphic and igneous rocks that are bounded to the south and east by basin-fill deposits in California’s Ivanpah Valley. The two main groups of rocks in the Mountain Pass area are Early Proterozoic high-grade metamorphic rocks and Middle Proterozoic ultrapotassic rocks and monazitic carbonatites, which carbonatites are associated with higher levels of REE. The total orebody strike length is approximately 2,750 feet and dip extent is 3,000 feet; true thickness of the more than 2% total rare earth oxide (“TREO”) grade

zone ranges between 15 feet and 250 feet. The percentage of each rare earth material contained in typical Mountain Pass bastnaesite concentrate is estimated to be as follows:

(1)See the “Rare Earth Resources and Reserves” section below for definition.

Independence Facility

The Company owns approximately 18 acres of land in Fort Worth, Texas, on which it is developing Independence, a metal, alloy, and magnet manufacturing facility as part of its Stage III strategy. The building and building improvements were substantially completed in the fourth quarter of 2023. In the fourth quarter of 2024, the Company commissioned machinery and equipment used in the manufacturing of NdPr metal, including electrolysis cells, and placed into service certain other machinery and equipment necessary for the production of other magnetic precursor products, such as strip casters. Installation and construction related to certain magnet manufacturing processes and equipment continues within the building. The Independence Facility supports the Magnetics segment.

Corporate Office

The Company has a lease for corporate office space at 1700 S. Pavilion Center Drive, Suite 800, Las Vegas, Nevada 89135. The lease has an initial term of 91 months expiring in October 2030, with an option to renew for one five-year period at the Company’s election.

Rare Earth Resources and Reserves

Introduction

Mineral resources and mineral reserves were estimated by SRK Consulting (U.S.) Inc. (“SRK”) for inclusion in this Annual Report. Pursuant to the requirements of Regulation S-K Subpart 1300 (“S-K 1300”), SRK prepared a pre-feasibility level Technical Report Summary for Mountain Pass with an effective date of October 1, 2024 (the “2024 TRS”) (refer to Exhibit 96.1 to this Annual Report). The mineral resource and mineral reserve estimated in the 2024 TRS were subsequently depleted by SRK to present an estimate of our resources and reserves as of December 31, 2024. The depletion removed by SRK represents resources and reserves that were extracted from the Mountain Pass open pit from October 1, 2024, through December 31, 2024.

Mineral Resource and Mineral Reserve Definitions

Mineral Resources

Item 1300 of 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, taking into account relevant factors such as cut-off grade (“COG”), 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 may not be considered when assessing the economic viability of a mining project and may not be converted to a mineral reserve.

Mineral Reserves

Item 1300 of S-K 1300 defines a “mineral reserve” as an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. A “proven mineral reserve” 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.

Estimation Methodology

Mineral Resources

The mineral resource estimate has been constrained by a geological model considering relevant rock types, structure, and mineralization envelopes as defined by TREO content within relevant geological features. This geological model is informed principally by diamond core drilling and multiple phases of geological mapping. Sectional interpretation based on the combination of these data were used to influence implicit modeling of the geological data with manual controls where appropriate. Data has been composited to reasonable lengths based on the original sample lengths and expected mining unit scale, and outliers have been addressed during estimation using restrictions on influence.

A number of internal controls have been applied over the history of the Mountain Pass deposit to demonstrate the consistency and reliability of historical analytical data supporting mineral resource estimation. Almost all data supporting the mineral resource has been generated by an iteration of a site-based laboratory at the Mountain Pass mine. The Mountain Pass laboratory uses various quality assurance and quality control (“QA/QC”) measures to calibrate modern equipment and ensure analytical precision and accuracy. QA/QC generated by previous laboratories has undergone check assays at independent third-party laboratories, and generally demonstrate no consistent bias. The quality analytical database is also supported by a limited amount of blind quality control samples inserted during a re-assay program, including site-specific standards of known TREO content, a variety of duplicate samples, and blank samples. The implementation and results of these various QA/QC programs have not been fully aligned with current industry standards and are not comprehensive but are considered satisfactory for use in mineral resource estimation.

Estimates have been validated to the input data using statistical and visual comparisons, localized swath plot comparisons of mean grades, and review of the limited mine production reconciliation data to the model. In general, estimates of grade quality are shown to align closely with the input exploration data, but have been demonstrated to be under-reporting relative to the grade control drilling. SRK has categorized uncertainty and risk at Mountain Pass by classifying the contained mineral resource by varying degrees of confidence in the estimate. The mineral resources at the Mountain Pass deposit have been classified in accordance with S-K 1300 definitions. The classification parameters are defined by the distance to composited data, the number of drillholes used to inform estimated block grades and a geostatistical indicator of relative estimation quality (kriging efficiency). As an overall modifier to classification, SRK considered the results from the QA/QC noted above and the observed variability in production reconciliation in the mineral resource classification as well, both of which preclude the assignment of measured resources, as defined by the SEC. Bulk density is based on average density measurements collected from the various rock types over the years, and carbonatite density in particular is supported by extensive mining and processing experience with the materials.

An economic COG of 2.35% TREO has been developed to ensure that material reported as a mineral resource can satisfy the definition of having reasonable prospects for economic extraction as required for the SEC definition. Mineral resources have been constrained within an optimized economic pit shell based on reserve input parameters, with the exception of the assumed REO selling prices, which are set 15% higher than the reserves price.

For mineral resources, a revenue factor of 1.0 is selected which corresponds to a break-even pit shell volume. SRK notes that the pit selected for mineral resources has been influenced by setbacks relative to critical infrastructure such as the tailing storage and the mill and flotation facilities.

A description of the methodology used to calculate mineral resources is provided in Exhibit 96.1 to this Annual Report.

Mineral Reserves

SRK developed a life-of-mine (“LoM”) plan for the Mountain Pass operation in support of mineral reserves. The Company operates a separations facility at Mountain Pass that allows it to separate bastnaesite concentrate into four individual REO products for sale. The Company further expects to install an ore sorting (pre-concentration) facility during 2025 to upgrade mined ore that is in the 2.5% to 5.0% TREO grade range. The Company expects that the separations and ore sorting facilities will both achieve full design capacity during 2026.

For economic modeling of the mineral reserves, SRK assumed that production will be a combination of bastnaesite concentrate sales and sales of four individual REO products: neodymium and praseodymium (previously defined as “NdPr”) oxide; samarium, europium, and gadolinium (“SEG+”) precipitate; lanthanum carbonate; and cerium chloride. Forecast economic parameters are based on historical cost performance for process, transportation, and administrative costs, as well as a first principles estimation of future mining costs. Forecast revenue from concentrate sales and individual separated product sales is based on a preliminary market study commissioned by the Company.

Pit optimization was performed based on prices that were established by the preliminary market study. The results of pit optimization guided the design and scheduling of the ultimate pit. SRK generated a cash flow model which indicated positive economics for the 30-year LoM plan, which provides the basis for the reserves. Reserves within the new ultimate pit are sequenced for approximately 25 years (Q4 2024 through 2048), with processing of stockpile material to occur for a further approximately 5 years (2049 through early 2053).

The costs used for pit optimization include estimated mining, processing, sustaining capital, transportation, and administrative costs, including an allocation of corporate costs. Processing and SG&A costs used for pit optimization were based on historical actual costs.

Processing recovery for concentrate is variable based on a mathematical relationship to estimate overall TREO recovery versus ore grade. The calculated COG for the reserves is 2.50% TREO, which was applied to indicated blocks contained within an ultimate pit, the design of which was guided by economic pit optimization.

The optimized pit shell selected to guide final pit design was based on a combination of the revenue factor (“RF”) 0.45 pit (used on the north half of the deposit) and the RF 1.00 pit shell (used on the south half of the deposit). The inter-ramp pit slopes used for the mineral reserves pit design are based on geotechnical studies and range from 44° to 47°.

Measured resources in stockpiles were converted to proven reserves. Indicated pit resources were converted to probable reserves by applying the appropriate modifying factors to potential mining pit shapes created during the mine design process. Inferred resources present within the LoM pit are treated as waste. Internal controls to demonstrate the consistency and reliability of the historic analytical data supporting the mineral resource estimate (which forms the basis for the mineral reserve estimate) are discussed above.

A description of the methodology used to calculate mineral reserves is provided in Exhibit 96.1 to this Annual Report.

Results

Mineral Resources

As of December 31, 2024, SRK estimates total indicated resources of 4.35 million STs with an average grade of 3.71% TREO and 13.35 million STs of inferred resources with an average grade of 4.79% TREO. Mineral resources are reported exclusive of mineral reserves. The reference point for mineral resources is in situ material.

(1)TREO% represents the total of individually assayed light rare earth oxides on a 99.7% basis of total contained TREO, based on the historical site analyses.

(2)Percentage of individual light rare earth oxides are based on the average ratios; La2O3 is calculated at a ratio of 32.6% grade of TREO% equivalent estimated grade, CeO2 is calculated at a ratio of 49.9% of TREO% equivalent estimated grade, Pr6O11 is calculated at a ratio of 4.3% of TREO% equivalent estimated grade, Nd2O3 is calculated at a ratio of 12.1% of TREO% equivalent estimated grade, and Sm2O3 is calculated at a ratio of 0.9% of TREO% equivalent estimated grade. The sum of light rare earths averages 99.7%; the additional 0.3% cannot be accounted for based on the analyses available to date and has been discounted from this resource statement.

General Notes:

• Mineral resources are reported exclusive of mineral reserves.

• Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources estimated will be converted into the mineral reserves estimate.

• Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, any apparent rounding errors are considered insignificant.

*•*The mineral resource model has been depleted for historical mining based on the December 31, 2024, pit topography.

• Pit optimization is based on pit slope angles of 39° to 45° including ramps and the following assumed prices: Rare Earth Mineral Concentrate $11.73 per kilogram (“kg”), PrNd Oxide $143.55/kg, SEG+ Precipitate $55.45/kg, La Carbonate $1.66/kg and Ce Chloride $2.96/kg.

• Pit optimization is based on concentrator recovery that varies based on the grade of the ore fed to the concentrator. The average REO distribution in the concentrate is PrNd (15.7%), SEG+ (1.8%), Lanthanum (32.3%) and Cerium (50.2%). Overall recoveries at the onsite separations plant as applied to concentrate containing on average 60% TREO are: PrNd Oxide (89.7%), SEG+ Precipitate (97.9%), La Carbonate (75.0%) and Ce Chloride (11.5%).

• Pit optimization is based on the following costs: mining cost at the pit exit of $1.50 per ST mined plus $0.05 per ST mined for each 15 feet bench above or below the pit exit, sorted ore rehandling ($2.55 per ST of sorted ore mined); non-sorted ore rehandling ($2.17 per ST of non-sorted ore mined), crushing ($3.66 per ST of ore crushed); ore sorting ($1.80 per ST ore fed to ore sorters), concentrating ($50.05 per ST of ore fed to concentrator), general and administrative ($28.82 per ST of ore fed to the concentrator), separations (includes a fixed annual cost and a variable cost of $1,080.59 per ST of concentrate processed on site), finished product shipping ($146.92 per ST shipped) and sustaining capital ($33.23 per ST of ore fed to the concentrator).

• The mineral resource statement reported herein only includes the REE cerium, lanthanum, neodymium, praseodymium, and samarium (often referred to as LREE). While other REE, often referred to as HREE, are present in the deposit, they are not accounted for in this estimate due to historic data limitations.

The following table is provided to show the change in mineral resources from December 31, 2023, to December 31, 2024:

(1)Percentages may not recompute as presented due to rounding.

The difference as compared to the previous year is due to inferred resources located within the mineral reserve pit that were mined and processed during 2024, assumed improvements in metallurgical recovery, and a change in the mineral resource COG due to updated project economics.

Mineral Reserves

As of December 31, 2024, SRK estimates total proven reserves of 0.81 million STs of ore with an average grade of 4.06% TREO and 28.88 million STs of probable reserves with an average ore grade of 6.02%. The Company’s total proven and probable reserves are estimated as 29.69 million STs with an average grade of 5.97%. The reference point for the mineral reserves is material delivered to the Mountain Pass crushing facility.

Based on these estimated reserves, the Company’s expected remaining mine life as of December 31, 2024, is approximately 29 years (2025 through 2053) to complete the processing of stockpiles and separations.

The following table states the amount of the Company’s proven and probable mineral reserves as of December 31, 2024.

General Notes:

• Reserves stated as contained within an economically mineable open pit design stated above a 2.50% TREO COG.

• Mineral reserves tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.

• MY% (mass yield) calculation is based on 60% concentrate grade of the product and the ore grade dependent metallurgical recovery. MY% = (TREO% * Met recovery)/60% concentrate TREO grade.

• Indicated mineral resources have been converted to probable reserves. Measured mineral resources have been converted to proven reserves.

• Reserves are diluted at the contact of the 2% TREO geological model triangulation (further to dilution inherent to the resource model and assume selective mining unit of 15 feet x 15 feet x 30 feet).

• Mineral reserves tonnage and grade are reported as diluted.

• Pit optimization is based on pit slope angles of 39° to 45° including ramps and the following assumed prices: Rare Earth Mineral Concentrate $10.20/kg, PrNd Oxide $124.83/kg, SEG+ Precipitate $48.22/kg, La Carbonate $1.44/kg and Ce Chloride $2.57/kg.

• Pit optimization is based on concentrator recovery that varies based on the grade of the ore fed to the concentrator. The average REO distribution in the concentrate is PrNd (15.7%), SEG+ (1.8%), Lanthanum (32.3%) and Cerium (50.2%). Overall recoveries at the onsite separations plant as applied to concentrate containing on average 60% TREO are: PrNd Oxide (89.7%), SEG+ Precipitate (97.9%), La Carbonate (75.0%) and Ce Chloride (11.5%).

• Pit optimization is based on the following costs: mining cost at the pit exit of $1.50 per ST mined plus $0.05 per ST mined for each 15 feet bench above or below the pit exit, sorted ore rehandling ($2.55 per ST of sorted ore mined); non-sorted ore rehandling ($2.17 per ST of non-sorted ore mined), crushing ($3.66 per ST of ore crushed); ore sorting ($1.80 per ST ore fed to ore sorters), concentrating ($50.05 per ST of ore fed to concentrator), general and administrative ($28.82 per ST of ore fed to the concentrator), separations (includes a fixed annual cost and a variable cost of $1,080.59 per ST of concentrate processed on site), finished product shipping ($146.92 per ST shipped) and sustaining capital ($33.23 per ST of ore fed to the concentrator).

• Reserves contain material inside and outside permitted mining but within mineral lease.

• Reserves assume 100% mining recovery.

• The strip ratio for the remaining reserves is 5.8 to 1 (waste to ore ratio).

• The mineral reserves were estimated by SRK.

The following table is provided to show the change in reserves from December 31, 2023, to December 31, 2024:

(1)Percentages may not recompute as presented due to rounding.

The primary reasons for the differences between the two reserves estimates are:

• The reserves were depleted by mining and processing that occurred during 2024. It is noted that reserves depletion due to mining and processing during 2024 was partially offset by additional above COG material that was identified by closely spaced blasthole sampling. This above COG material was not included in the previous reserves estimate because the material had not been identified by the wider spaced resource drilling that informed the resource block model utilized for the 2023 TRS.

• For the 2024 end-of-year reserves, it has been assumed that pre-concentration (ore sorting) will be applied to mined material having an in-situ grade that is in the 2.5% to 5.0% TREO grade range. As a result of pre-concentration, the average grade will be increased for the fraction of sorted material that is advanced to the concentrator. This grade uplift, which is supported by the results of test work performed during 2023 and 2024 on Mountain Pass ores, is expected to allow for improved recovery because metallurgical recovery at the concentrator is positively correlated with feed grade.

• For the 2024 end-of-year reserves, it also has been assumed that overall metallurgical recovery at the concentrator will improve due to the installation of a boiler that has enabled flotation to be conducted at a constant higher temperature, as well as new reagent testing and blending of historically problematic ores. The overall improvements in metallurgical recovery are supported by a plant monitoring campaign that was conducted to evaluate concentrator performance during July and August of 2024.

Factors and Assumptions Affecting Mineral Resource and Mineral Reserve Estimates

There are numerous uncertainties inherent in estimating quantities and qualities of REO reserves and costs to mine recoverable reserves, including many factors beyond our control. We will regularly evaluate our REO reserve estimates. This may be done in conjunction with additional exploration drilling programs. The estimates of REO reserves as to both quantity and quality will also be updated to reflect new drilling or other data received. Estimates of economically recoverable REO

reserves, however, necessarily depend upon a number of variable factors and assumptions, all of which may vary considerably from actual results, such as:

• geological, mining and processing conditions and/or effects from prior mining that may not be fully identified by available data or that may differ from experience;

• the strategic approach to mining and processing the deposit may change depending upon market demand, corporate strategy and other prevailing economic conditions;

• assumptions concerning future prices of rare earth products, foreign exchange rates, process recovery rates, transportation costs, operating costs, capital costs, and reclamation costs; and

• assumptions concerning future effects of regulation, including the issuance of required permits and taxes by governmental agencies and foreign government policy relating to import or export of rare earth products.

Actual REO tonnage recovered from identified REO reserves and revenues and expenditures with respect to the same may vary materially from estimates. Further, period-to-period, our future estimates of REO reserves may fluctuate significantly as macroeconomic conditions and our level of understanding with respect to the deposit change. These estimates may not accurately reflect our actual REO reserves. Any inaccuracy in our estimates related to our REO reserves could result in lower-than-expected revenues and higher-than-expected costs.

From time to time, we may be subject to legal and governmental proceedings and claims in the ordinary course of business. We are not currently a party to any material legal or governmental proceedings, and, to our knowledge, none is threatened.

You should read the following discussion and analysis of our financial condition and results of operations together with our Consolidated Financial Statements and related notes appearing elsewhere in this annual report on Form 10-K for the year ended December 31, 2024 (this “Annual Report”). A discussion of changes in our consolidated results of operations and cash flows between years ended December 31, 2023 and 2022, has been omitted from this Annual Report, but may be found in “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, Comparison of the Years Ended December 31, 2023, 2022, and 2021,” of our annual report on Form 10-K for the year ended December 31, 2023, filed with the U.S. Securities and Exchange Commission on February 28, 2024. This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. The actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including, but not limited to, those set forth under “Item 1A. Risk Factors” and elsewhere in this Annual Report. See also “Cautionary Note Regarding Forward-Looking Statements.”

Executive Overview

MP Materials Corp., including its subsidiaries (“we,” “our,” and “us”), is the largest producer of rare earth materials in the Western Hemisphere. We own and operate the Mountain Pass Rare Earth Mine and Processing Facility (“Mountain Pass”) located near Mountain Pass, San Bernardino County, California, the only rare earth mining and processing site of scale in North America. We are also developing a rare earth metal, alloy and magnet manufacturing facility in Fort Worth, Texas (“Independence” or the “Independence Facility”).

During the fourth quarter of 2024, we modified our segment structure largely as a result of initial production of magnetic precursor products. Beginning with the fourth quarter of 2024, our reportable segments, which are primarily based on our internal organizational structure and types of products, are our two operating segments—Materials and Magnetics. In conjunction with this change, where applicable, prior period amounts have been recast to conform to this new segment reporting structure.

The Materials segment operates Mountain Pass, which produces refined rare earth products as well as rare earth concentrate and related products. The Materials segment primarily generates revenue from (i) sales of rare earth concentrate, primarily sold for further distribution to a single, principal customer in China, and (ii) sales of neodymium-praseodymium (“NdPr”) oxide and metal, primarily sold to customers in Japan, South Korea, and broader Asia.

The Magnetics segment operates the Independence Facility, where we began production of magnetic precursor products in December 2024 and anticipate manufacturing neodymium-iron-boron (“NdFeB”) permanent magnets by the end of 2025. Beginning in the first quarter of 2025, we expect that the Magnetics segment will begin generating revenue from sales of NdPr metal to a single customer in the U.S.

Certain rare earth elements (“REE”) serve as critical inputs for the rare earth magnets inside the electric motors and generators powering carbon-reducing technologies such as hybrid and electric vehicles (referred to collectively as “xEVs”) and wind turbines, as well as drones, defense systems, robotics and many other high-growth, advanced technologies. Our integrated operations combine low production costs with high environmental standards, thereby restoring American leadership to a critical industry with a strong commitment to sustainability.

Highlights from the year ended December 31, 2024, include:

• Commenced production of magnetic precursor products at Independence in December 2024;

• Received a total of $100.0 million in customer prepayments for magnetic precursor products pursuant to the long-term supply agreement with GM;

• Continued NdPr sales momentum, including signing a supply agreement with a global automaker for a significant volume commitment;

• Achieved record rare earth oxide (“REO”) in concentrate production volume;

• Significantly advanced ramp-up of separated rare earth products production, producing record domestic NdPr oxide volumes;

• Issued $747.5 million of 2030 Notes (as defined below) in March 2024 and entered into Capped Call Options (as defined below) covering 34.4 million shares of common stock to offset potential dilution; concurrently repurchased a portion of our 2026 Notes (as defined below) at prices lower than the associated carrying amounts resulting in a $46.3 million gain on early extinguishment of debt;

• Received a $58.5 million Section 48C Qualifying Advanced Energy Project Tax Credit (the “48C Credit”) in March 2024 to support the construction of the Independence Facility;

• Repurchased 15.2 million or 8.6% of the Company’s outstanding shares at a total cost of $225.1 million at an average price of $14.76 per share through the Company’s share repurchase program that was implemented during the year;

• Completed a debt exchange in December 2024, reducing the principal amount of debt by $27.0 million by exchanging $142.3 million of 2026 Notes for $115.3 million of 2030 Notes; and

• Maintained a strong balance sheet with cash, cash equivalents and short-term investments totaling $850.9 million as of December 31, 2024, after incurring capital expenditures to advance construction of the Independence Facility, as well as various projects at Mountain Pass, including the HREE Facility.

Despite a continued weak pricing backdrop in 2024, our operating results for the Materials segment demonstrate solid operational execution. Our upstream concentrate operations delivered record production levels despite significant focus being spent on scaling midstream separated product operations. Although we remain well below our designed throughput of separated products, we have seen steady improvements throughout 2024. Furthermore, we expanded our customer base of separated rare earth products and steadily increased sales throughout the year. Although we continue to expect that it may take several quarters to achieve our designed throughput of separated products, we remain confident in our ability to achieve it in the future.

In addition, our Magnetics segment continued to make significant progress on our strategy to re-establish magnet manufacturing in the U.S., including commissioning our electrowinning capability to produce NdPr metal from NdPr oxide at Independence in the fourth quarter of 2024. Throughout 2024, we significantly advanced the organization’s engineering and manufacturing technology capabilities and meaningfully added to our magnetics team of scientists, technicians and engineers, with the team now comprised of over 100 employees. In addition, we recently began trial production of automotive-grade, sintered neodymium-iron-boron (“NdFeB”) magnets at our new product introduction (“NPI”) facility within Independence.

Recent Developments

2024 Offtake Agreement

In January 2024, we entered into a new offtake agreement with Shenghe (the “2024 Offtake Agreement”) that replaced and extended the offtake agreement entered into in March 2022 with Shenghe (the “2022 Offtake Agreement” and, together with the 2024 Offtake Agreement, the “Offtake Agreements”). The initial term of the 2024 Offtake Agreement is two years, with the option for us to extend the term for an additional one-year period. The terms of the 2024 Offtake Agreement are substantially the same as those of the 2022 Offtake Agreement with the exception of the addition of NdPr metal into the definition of non-concentrate rare earth products.

We have in the past and may in the future be exposed to certain market risks, including commodity price, foreign currency, and interest rate risks, in the ordinary course of our business, as discussed further below.

Commodity Price Risk

Our results of operations depend in large part upon the market prices of REO and particularly the price of rare earth concentrate and NdPr. Rare earth concentrate is not quoted on any major commodities market or exchange as product attributes vary and demand is currently constrained to a relatively limited number of refiners, a significant majority of which are based in China. NdPr pricing is primarily based off of indices in China.

NdPr represents a significant portion of the economic value of our rare earth concentrate. We expect demand for NdPr to continue to grow, driving demand for our concentrate, separated NdPr oxide, and in the future, permanent magnets containing NdPr. However, actual demand and pricing may fluctuate for numerous reasons beyond our control, including, among other things, supply of NdPr from other producers, discoveries of new mineral properties, technological changes that lead to diminished reliance on NdPr and/or permanent magnets, and shifts in underlying end-user demand for products or components manufactured with NdPr. We have not entered into derivative contracts to protect the price of our products, and do not expect to do so in the foreseeable future, as there is no liquid market for such contracts and their cost may be prohibitive, if they could be obtained at all.

The solvent extraction and finishing processes are highly reliant upon commodity reagents. These reagents, as well as certain other raw materials and supplies we use in our operations, are subject to price volatility caused by weather, supply conditions, political and economic variables and other unpredictable factors. We have not historically used options or swap contracts to manage the volatility related to the above exposures. When possible, we seek to limit our exposure by entering into long-term contracts and price increase limitations in contracts. Also, we use natural gas to operate our CHP plant, which powers our processing and separations facilities at Mountain Pass, and to power backup generators at the Independence Facility. We generally purchase or expect to purchase natural gas from suppliers at market or tariff rates. From time to time, we use commodity contracts to hedge energy exposures. Such commodity price fluctuations may cause volatility in our results of operations and cash flows in the future.

Foreign Currency Risk

While we currently generate revenue in the United States and in U.S. dollars, the market transactions are denominated mainly in the Chinese Yuan, and we are therefore exposed to currency volatility and devaluation risks. For example, we negotiate monthly U.S. dollar REO prices with Shenghe, which are based in part on the exchange rate between the U.S. dollar and the Chinese Yuan. Geopolitical tensions between the U.S. and China may lead to increased tariffs, preferences for local producers, some of which may be government-supported, changes in taxing regimes or other trade barriers. Foreign currency risk has not historically had a material impact on our results of operations or cash flows. However, as we expand internationally, we become further exposed to foreign currency risk by entering new markets with additional foreign currencies. The economic impact of currency exchange rate movements is often linked to variability in real growth, inflation, interest rates, governmental actions and other factors. Accordingly, to the extent that foreign currency risk becomes material, we may enter into hedging transactions to manage our exposure to fluctuations in foreign currency exchange rates.

Equity Market and Interest Rate Risk

Convertible Notes

While the fair values of our Convertible Notes are subject to interest rate risk, market risk and other factors due to their convertible feature, the Convertible Notes are more sensitive to the equity market price volatility of our stock price than changes in interest rates. In March 2024, in connection with the offering of the 2030 Notes, we entered into Capped Call Options with the Counterparties. The Capped Call Options are expected generally to reduce the potential dilution to our common stock upon any conversion of the 2030 Notes.

The fair values of our Convertible Notes will generally increase as the price of our common stock increases and will generally decrease as the price of our common stock declines in value. The interest and market value changes affect the fair value of our Convertible Notes but do not impact our financial position, cash flows or results of operations due to the fixed nature of the debt obligations. Generally, the fair values of our Convertible Notes will increase as interest rates fall and decrease as interest rates rise. Over the past several years, the Federal Reserve raised interest rates in an effort to combat high inflation; however, with recent indicators that inflation is moderating, the Federal Reserve has recently begun to reduce interest rates.

Despite this shift in U.S. policy, uncertainty persists in the market and economic conditions, including the possibility of additional measures that could be taken by the Federal Reserve and other government agencies, related to concerns over inflation risk.

See Note 10, “Debt Obligations,” in the notes to the Consolidated Financial Statements for further information on our Convertible Notes.

Cash equivalents and short-term investments

We had cash, cash equivalents and short-term investments totaling $850.9 million as of December 31, 2024, of which $849.0 million was invested in money market funds, U.S. Treasury and agency securities, commercial paper and certificates of deposit. Our cash, cash equivalents and short-term investments are held for working capital and general corporate purposes. We have not historically entered into investments for trading or speculative purposes.

Our cash equivalents and short-term investments are subject to market risk due to changes in interest rates. Fixed-rate securities may have their market value adversely affected due to a rise in interest rates. Due in part to these factors, our future investment income may fall short of our expectations due to changes in interest rates or we may suffer losses in principal if we are forced to sell securities that decline in market value due to changes in interest rates. As our short-term investments are classified as available-for-sale, no gains are recognized due to changes in interest rates. As losses due to changes in interest rates are generally not considered to be credit related, no losses in such investments are recognized due to changes in interest rates unless we intend to sell, it is more likely than not that we will be required to sell, we sell prior to maturity, or we otherwise determine that all or a portion of the decline in fair value is due to credit related factors.

As of December 31, 2024, a hypothetical increase of 100-basis points in interest rates would not have a material impact on the value of our cash equivalents or short-term investments in our Consolidated Financial Statements.

MP Materials Corp.:

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of MP Materials Corp. and subsidiaries (the Company) as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive income (loss), changes in stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2024, and the related notes (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024 based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting 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 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, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements 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. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s 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 the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Identification and disclosure of related party transactions with Shenghe

As discussed in Note 19 to the consolidated financial statements, the Company has entered into a series of commercial agreements with Shenghe Resources (Singapore) International Trading Pte. Ltd (Shenghe), a related party. Under the agreements, Shenghe purchases rare earth products produced by the Company at specified prices.

We identified the identification and disclosure of the related party transactions with Shenghe as a critical audit matter. Subjective auditor judgment was required in assessing the sufficiency of the procedures performed to determine whether all such transactions were identified and disclosed properly by the Company.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the identification and disclosure of transactions with Shenghe. We applied auditor judgment to determine the nature and extent of procedures to be performed to identify transactions with Shenghe. We evaluated the identification and disclosure of transactions with Shenghe by:

• inquiring of management of the Company and the Audit Committee of the Board of Directors regarding (i) the Shenghe relationship and (ii) transactions between the Company and Shenghe

• reading the minutes from meetings of the Board of Directors

• obtaining and analyzing underlying documentation for a sample of sales transactions and comparing it to the contractual agreements with Shenghe

• confirming transactions and contractual agreements with Shenghe as of and for the year ended December 31, 2024 and comparing the responses to the Company’s c
