 Item 1. BUSINESS

 Piedmont Lithium Inc. ("Piedmont Lithium," "Piedmont", "we," "us," "our," or "Company") is a U.S.-based, development-stage company advancing a multi-asset, integrated lithium business in support of a clean energy economy and U.S. and global energy security. We plan to supply lithium hydroxide to the electric vehicle and battery manufacturing supply chains in North America by processing spodumene concentrate produced from assets we own or in which we have an economic interest.
 Our portfolio includes our wholly-owned Carolina Lithium, a proposed fully integrated spodumene ore-to-lithium hydroxide project in Gaston County, North Carolina. The balance of our project portfolio includes strategic investments in lithium assets in Quebec, Canada, including the operational NAL mine; in Ghana, West Africa with Atlantic Lithium, including the Ewoyaa project; and in Newfoundland, Canada with Vinland Lithium, including the Killick Lithium project.
 Piedmont Lithium incorporated in the State of Delaware on December 3, 2020. We maintain executive offices at 42 E Catawba Street, Belmont, NC, 28012, and our telephone number is (704) 461-8000. Our website address is www.piedmontlithium.com. Shares of our common stock, par value $0.0001 per share, are traded on the Nasdaq under the symbol "PLL" and our CDIs, each representing 1/100th of a share of our common stock, are traded on the ASX, also under the symbol "PLL."

 Proposed Merger with Sayona Mining
 On November 18, 2024, we entered into the Merger Agreement with Sayona Mining, whereby Piedmont and Sayona Mining will be combined on a stock-for-stock basis where each share of Piedmont common stock, par value US$0.0001 per share, issued and outstanding immediately prior to the consummation of the Merger, subject to certain exclusions, shall be converted into the right to receive from Sayona Mining 527 Sayona Mining ordinary shares.
 Consummation of the Merger, which is expected to occur mid-2025, is subject to certain closing conditions, including requisite approvals of Piedmont's stockholders and Sayona Mining's shareholders of the Merger Agreement. The Merger Agreement contains certain termination rights in favor of Sayona Mining and Piedmont, including if the Merger is not consummated on or before September 30, 2025 or if the requisite approvals of Sayona Mining shareholders and Piedmont stockholders are not obtained.
 The foregoing summary of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the terms and conditions of the Merger Agreement, a copy of which is attached as Exhibit 2.1 to this Annual Report.
 See Part I, Item 1A -"Risk Factors-Risks Related to the Merger Agreement" in this Annual Report for additional information about the Merger.

 Our Segment
 We have one operating segment, which is also our reportable segment. Our CODM, who is also our CEO, manages our operations on a consolidated basis for purposes of allocating resources.

 Strategy
 Our strategic goal is to become a leading producer of lithium products in North America, supplied by geographically diverse and sustainable spodumene assets. North American demand for lithium continues to grow as a cornerstone material for the global energy transition, including the manufacturing of electric vehicles and development of energy storage systems. We believe our global portfolio of hard rock lithium assets should support a level of estimated lithium hydroxide production that will dramatically increase current production of lithium hydroxide in the United States.
 Our plan is to produce battery-grade lithium hydroxide from spodumene concentrate. We believe spodumene concentrate represents the lowest-risk and most commercially scalable raw material source for the production of lithium hydroxide. Within our production process, we expect to use Metso's pressure leach technology as well as a number of manufacturing processes commonly used in the lithium industry today. We plan, as part of our sustainability goals within our overall ESG strategy, to develop our greenfield operation in North Carolina as one of the most sustainable lithium hydroxide production operations in the world.
 Our portfolio, which includes Carolina Lithium and strategic equity investments, are being developed on a measured timeline to optimize both near-term cash flow and long-term value maximization. At production, we expect to have an estimated lithium hydroxide manufacturing capacity of 60,000 metric tons per year, as compared to the current total estimated U.S. lithium hydroxide production capacity of approximately 20,000 metric tons per year. In support of our strategy, we continue to evaluate opportunities to further expand our resource base and production capacity.

 Developing an Integrated Lithium Production Business—Key Projects
 Piedmont Lithium owns an equity interest of 25% in Sayona Quebec, which owns full equity interests in the NAL, Authier, Tansim, and Vall e properties. These projects are located in the Abitibi region of Quebec, Canada. We also hold an offtake agreement with Sayona Quebec for the greater of 113,000 dmt per year or 50% of annual spodumene concentrate production at market prices, subject to a price floor of $500 per dmt and a price ceiling of $900 per dmt for SC6, on a life-of-mine basis.
 In February 2024, we sold approximately 1,250 million shares of Sayona Mining for an average of $0.03 per share. The shares sold represented approximately 12% of Sayona Mining's outstanding shares and resulted in $41.4 million in net proceeds. The sale of these shares has no impact on Piedmont Lithium's joint venture or offtake rights with Sayona Quebec.
 NAL restarted production of spodumene concentrate in March 2023 and achieved steady-state production in June 2024. NAL progressively set record quarterly production levels of 40,439 dmt, 49,660 dmt, and 52,141 dmt, in the first quarter, second quarter, and third quarter, respectively, followed by 50,922 dmt in the fourth quarter, with significant increases in ore mined, mill utilization, and global recovery rates during 2024.
 Sayona Mining achieved record production for the one-year period ended December 31, 2024, producing 193,162 dmt, of which 116,700 dmt were delivered to Piedmont Lithium in accordance with our offtake agreement. We, in turn, sold 116,700 dmt to our customers to whom we supply through offtake and purchase agreements, all of which contain market-based pricing mechanisms. We utilized an updated commercial strategy in the second half of 2024 to take advantage of lithium futures markets, resulting in an industry-leading realized spodumene concentrate price in the third and fourth quarters of 2024. Improved profitability was also the result of consolidation of shipments with Sayona Quebec, which reduced transportation costs. NAL completed construction of its tailings storage facility in the first quarter of 2024 and a crushed-ore dome in the second quarter of 2024. The completion of the dome contributed to the achievement of steady-state production in the second quarter of 2024 and is expected to be key in achieving full run-rate production throughput at NAL, thereby allowing for improved overall availability in the operation and resulting in meaningfully lower unit production costs. Increased blasting efficiencies and dilution management were utilized to deliver higher grades of ore to the plant in the second half of 2024. Continuing improvement of operating costs will be a key focus for NAL in 2025.
 In addition to spodumene mining and concentrate production, NAL's facilities also include a partially completed lithium carbonate plant, which was developed by a prior operator of NAL. In the event both we and Sayona Mining decide to jointly construct and operate a lithium conversion plant through our jointly-owned entity, Sayona Quebec, then spodumene concentrate produced from NAL would be preferentially delivered to that conversion plant upon commencement of conversion operations. Any remaining spodumene concentrate not delivered to a jointly owned conversion plant would first be delivered to Piedmont Lithium up to our offtake right and then to third parties.

 In the third quarter of 2024, Sayona Mining announced an increase to the mineral resource estimate at NAL, including an increase to the mineral resources in the measured and indicated categories in accordance with JORC Code requirements.

 Ghana
 As of December 31, 2024, we have the ability to earn a 50% equity interest in Atlantic Lithium Ghana, which includes Ewoyaa. In August 2023, we exercised our option, to acquire an initial 22.5% equity interest, and expect to earn an additional 27.5% equity interest, subject to funding the first $70 million of development costs for Ewoyaa. Once our equity interests are acquired, and if both the mining lease is ratified and the agreement with MIIF is executed, Piedmont Lithium and Atlantic Lithium expect to each own a 40.5% equity interest in Ewoyaa. MIIF is expected to own a 6% equity interest in Ewoyaa, with the Government of Ghana expected to obtain a 13% free-carried interest in accordance with the mining lease. As of December 31, 2024, we have not received any shares in Atlantic Lithium Ghana.
 Additionally, we hold an offtake agreement for 50% of annual production of spodumene concentrate from Ewoyaa at market prices on a life-of-mine basis, subject to our satisfaction of certain development cost funding requirements. Ewoyaa is Atlantic Lithium's flagship project in the Cape Coast region of Ghana and located approximately 70 miles from the Port of Takoradi, a major port via a national highway. We anticipate the development of the Ewoyaa project to be key for delivering spodumene concentrate to the market.
 In January 2024, MIIF commenced its investment in Atlantic Lithium through its purchase of Atlantic Lithium's common stock totaling $5 million. In September 2023, Atlantic Lithium had announced that MIIF plans to invest (i) $27.9 million to acquire a 6% stake in Ewoyaa and (ii) $5 million in Atlantic Lithium's common stock to help further, in part, the development of Ewoyaa. As part of these investments, it is our understanding that MIIF intends to fund 6% of all future exploration and development costs within Atlantic Lithium Ghana. These funds are expected to equally reduce Piedmont Lithium's and Atlantic Lithium's capital expenditure contributions for Ewoyaa.
 In January 2024, we sold 24.5 million shares of Atlantic Lithium, for an average price of $0.32 per share, after which we retained shares representing approximately a 5% ownership interest. The shares sold resulted in net proceeds of $7.7 million.
 In July 2024, the application to grant the Ewoyaa mining lease was submitted to the Ghanaian parliament to undergo the ratification process. The mining lease remains subject to parliamentary ratification as of the date of this Annual Report. Ewoyaa made key strides on the regulatory front in the second half of 2024 with the receipt of the environmental permit granted by Ghana's Environmental Protection Agency in September 2024 and the Mine Operating Permit issued by the Minerals Commission of Ghana in October 2024.

 Carolina Lithium is a development stage, hard rock lithium project located within the renowned Carolina Tin-Spodumene Belt of North Carolina and in close proximity to lithium markets. Carolina Lithium is expected to consist of a mining operation, a concentrator, and a lithium hydroxide conversion plant. The conversion plant is expected to be developed in phases and produce 60,000 metric tons of lithium hydroxide per year at full capacity. Due to the expected quality of this hard rock lithium asset, integration of the operation, existing infrastructure, and proximity to lithium and byproduct markets, we believe Carolina Lithium will be one of the lowest cost lithium hydroxide manufacturing operations in the world.
 We received the mining permit for Carolina Lithium in 2024 and continue to engage in permitting activities with state and local agencies. In August 2021, we submitted a mining permit application to the NCDEQ's DEMLR. Following our submission, we responded to a series of additional information requests made by DEMLR. In April 2024, DEMLR approved the mining permit application and issued the finalized permit in May 2024 following our posting of the required reclamation bond. A Prevention of Significant Deterioration – Title V Air Permit application was submitted to the NCDEQ Division of Air Quality and deemed complete in February 2023, and remains under review. We previously worked with the NCDEQ Division of Water Resources on a National Pollutant Discharge Elimination System permit for the site; however, we recently pivoted toward pursuit of North Carolina General Stormwater permits instead. As a result, we have withdrawn our National Pollutant Discharge Elimination System permit applications and submitted applications required to obtain North Carolina General Stormwater permits for both the conversion plant as well as the mine and concentrator operations.
 Our goal in 2025 is to obtain the remaining material state permits for Carolina Lithium and assess the timeline for rezoning activities. The timeline for project development will take into consideration strategic partnerships and project financing activities, as well as market conditions.

 Tennessee Lithium
 Following the receipt of our Carolina Lithium state mining permit in the second quarter of 2024, and in response to changing market conditions, we consolidated our U.S. project development strategy by shifting the proposed Tennessee Lithium conversion capacity to Carolina Lithium. The updated strategy is designed to deploy capital and technical resources more efficiently and leverage our foundational North Carolina project with the potential for up to 60,000 metric tons of lithium hydroxide production per year.
 The conversion capacity is expected to include two lithium hydroxide trains constructed in a phased approach. The bulk of previously completed front-end engineering work for Tennessee Lithium will be transferred to Carolina Lithium.
 In 2024, we exited both our option agreement to purchase the proposed site for Tennessee Lithium and our purchase agreement to acquire an existing industrial facility in close proximity to our proposed Tennessee project site. We currently maintain in care and maintenance a 132-acre disposal facility adjacent to the former proposed Tennessee Lithium site, with the intention to sell the property in due time.

 Strengths
 We believe that we are well-positioned to successfully execute our business strategies primarily due to our following competitive strengths:
 • Revenue generation from NAL—NAL, the largest producing lithium mine in North America, achieved run rate and multiple quarterly production records in 2024. We hold an offtake agreement with Sayona Quebec for the greater of 113,000 dmt per year or 50% of spodumene concentrate production from NAL at market prices, subject to a price floor of $500 per dmt and a price ceiling of $900 per dmt for SC6, on a life-of-mine basis. We, in turn, sell spodumene concentrate procured under our NAL offtake to Piedmont Lithium's customers at market-based prices.
 • Scale and diversification of resources—We own or hold interests in three significant spodumene resources located in Quebec, Ghana, and North Carolina. Beginning in January 2021, we have made investments in key spodumene resources and have established strategic partnerships with Sayona Mining and Atlantic Lithium. We continue to pursue opportunities to complement our business through additional acquisitions, joint ventures, strategic alliances, and investments.
 • Advantageous locations and infrastructure—NAL is located in a well-established mining district within the Abitibi region of Quebec, Canada. The region provides access to infrastructure and is geopolitically advantageous. NAL is near the major mining town of Val-d'Or, Quebec, with access to rail, hydropower, and a skilled labor workforce. NAL has a partially completed lithium carbonate facility on site, which was developed by a previous operator. Ewoyaa is located in the Cape Coast region of Ghana with available power infrastructure nearby and direct highway access to Accra, which is approximately 60 miles from Ewoyaa. Ewoyaa also is approximately 70 miles from the deep-water Port of Takoradi, providing reasonable transport of spodumene concentrate. Carolina Lithium is well situated in a historical lithium region within the developing "Battery Belt." The area features access to road and rail infrastructure, a highly skilled labor workforce, low-cost and low-carbon sources of baseload grid power, and research and development centers for lithium manufacturing.
 • U.S.-based company—As a U.S.-domiciled and listed company with a U.S.-based proposed lithium project, Piedmont Lithium should benefit from policies aimed at supporting growth in the domestic battery supply chain and reducing reliance on foreign nations. These policies include the IRA's Advanced Manufacturing Production Credit (Section 45X), which is available only to U.S. taxpayers and provides certain tax incentives for the production of applicable critical minerals. This credit is in addition to the opportunities available through the DOE's ATVM loan program and DPA Title III loans or grants.
 • Strategic funding—We are evaluating a variety of funding options to support development objectives aimed at maintaining shareholder value in the capital markets. ATVM, DPA loan(s) or grants, if awarded, are expected to cover a significant share of the capital required to develop Carolina Lithium, thereby strengthening the opportunity for strategic parties. Strategic partnerships, offtake prepayments, mineral royalties, and other opportunities are being considered to support the development of our projects and equity investments.
 • Greenfield opportunities—Carolina Lithium is being designed as a new operation, which offers the opportunity to leverage modern technologies, systems, and procedures. We expect to utilize the innovative Metso pressure leach technology to convert spodumene concentrate to lithium hydroxide at this U.S. project. This technology is expected to provide a relative advantage in capital and operating costs and supports our ESG strategy to create a more sustainable operating profile as compared to other hard rock lithium conversion methods.
 • Highly experienced management team—The Company is led by a highly experienced management team and has strong execution capabilities across all key functions.

 Marketing, Sales, and Principal Markets
 We continue to explore potential strategic partnerships and sales, offtake, and marketing agreements that will benefit the development of our assets as well as the U.S. electric vehicle supply chain.

 Customers
 On August 30, 2024, we entered into an amended offtake agreement with Tesla, Inc. to supply 125,000 dmt of spodumene concentrate from NAL. The term of the agreement runs through September 2026. Pricing is determined by a market-based mechanism. The initial term can be extended for an additional three years upon mutual agreement.
 On February 16, 2023, we entered into a spodumene concentrate offtake agreement with LG Chem to sell 200,000 dmt of spodumene concentrate from our NAL offtake agreement. The term of the agreement expires four years from the date of first shipment or upon the delivery of 200,000 dmt. Pricing is determined by a market-based mechanism.
 In addition to our offtake customers, we have entered into a series of purchase agreements with major international trading companies to facilitate individual sales. These purchase agreements provided for the delivery of spodumene concentrate primarily on an FOB vessel basis (Incoterms 2020) and included a partial prepayment convention.

 Competition and Market Barriers
 We compete with other mineral and chemical processing companies in connection with the acquisition of suitable exploration properties and the engagement of qualified personnel. Many of our competitors possess greater financial resources and technical capabilities than Piedmont Lithium. Although we aspire to be a leading lithium hydroxide producer in North America, the lithium mining and chemical industries are fragmented. We are one of many participants in these sectors. Many of our competitors, as compared to us, have been in business longer, have established more strategic partnerships and relationships, and have greater financial accessibility.
 While we compete with other exploration companies in acquiring suitable properties, we believe there will be readily available purchasers of lithium chemical products or other industrial minerals if they are produced from any of our owned or leased properties. The price of our planned products may be affected by factors beyond our control, including fluctuations in the market prices for lithium, supplies of lithium, demand for lithium, and mining activities of others.
 If we identify lithium mineralization that is determined to be of economic grade and in sufficient quantity to justify production, additional capital would be required to develop, mine, process, and sell such production. Our strategic partners, in which we have equity investments, face similar challenges as discussed above.

 Government Regulations
 Exploration and development activities for our projects are subject to extensive laws and regulations, which are overseen and enforced by multiple U.S. federal, state, and local authorities as well as foreign jurisdictions. These applicable laws govern exploration, development, production, exports, various taxes, labor standards, occupational and mine health and safety, waste disposal, protection and remediation of the environment, protection of endangered and protected species, and other matters. Various permits from government bodies are required for drilling, mining, or manufacturing operations to be undertaken, and we cannot be assured such permits will be received. Environmental laws and regulations may also, in addition to other requirements;
 • require notice to stakeholders of proposed and ongoing exploration, drilling, environmental studies, mining, or production activities;
 • require the installation of pollution control equipment;
 • restrict the types, quantities and concentrations of various substances that can be released into the environment in connection with exploration, drilling, mining, lithium hydroxide manufacturing, or other production activities;
 • limit or prohibit drilling, mining, lithium manufacturing or other production activities on lands located within wetlands, areas inhabited by endangered species and other protected areas, or otherwise restrict or prohibit activities that could impact the environment, including water resources;
 • impose substantial liabilities for pollution resulting from current or former operations on or for any preexisting environmental impacts from our projects;

 • require significant reclamation obligations in the future as a result of our mining and chemical operations; and
 • require preparation of an environmental assessment or an environmental impact statement.
 Compliance with environmental laws and regulations may impose substantial costs on us, subject us to significant potential liabilities, and have an adverse effect on our capital expenditures, results of operations, and competitive position. Violations and liabilities with respect to these laws and regulations could result in significant administrative, civil, and criminal penalties, remedial clean-ups, natural resource damages, permit modifications and/or revocations, operational interruptions and/or shutdowns, and other liabilities, as well as reputational harm, including damage to our relationships with customers, suppliers, investors, governments and other stakeholders. The costs of remedying such conditions may be significant, and remediation obligations could adversely affect our business, results of operations, and financial condition. Federal, state, and local legislative bodies and agencies frequently revise environmental laws and regulations, and any changes in these regulations, or the interpretations thereof, could require us to expend significant resources to comply with new laws or regulations or changes to current requirements and could have a material adverse effect on our business operations. As of the date of this Annual Report, other than with respect to the permitting activities of Carolina Lithium, we have not been required to spend material amounts on compliance regarding environmental regulations.
 Permits
 Obtaining and renewing governmental permits are complex and time-consuming processes and involves numerous jurisdictions, public hearings, and possibly costly undertakings. The timeliness and success of permitting efforts are contingent upon many variables not within our control, including the interpretation of permit approval requirements administered by the applicable permitting authority. We may not be able to obtain or renew permits that are necessary for our planned operations, or the cost and time required to obtain or renew such permits may exceed our expectations. Any unexpected delays or costs associated with the permitting process could delay the exploration, development and/or operation of our projects. For additional information, see Part I, Item 1A, "Risk Factors—We will be required to obtain governmental permits and approvals in order to conduct development and mining operations, a process that is often costly and time-consuming. There is no certainty that all necessary permits and approvals for our planned operations will be granted."
 In November 2019, we were granted a CWA Section 404 Standard Individual Permit from the U.S. Army Corps of Engineers for our integrated Carolina Lithium project. We received an updated preliminary jurisdictional determination in March 2022 based on an updated footprint of the integrated site.
 In July 2022, we received an updated CWA Section 401 Individual Water Quality Certificate from the NCDEQ Division of Water Resources for our Carolina Lithium project.
 In August 2021, we submitted a mining permit application to the NCDEQ's DEMLR. Since our submission, we have responded to a series of additional information requests made by DEMLR. In March 2024, we responded to the last round of DEMLR additional information requests which resulted in Piedmont's application being approved with the final permit received in May 2024.
 In September 2021, the Gaston County Board of Commissioners updated its Unified Development Ordinance which, in part, defines operational requirements for new mines and quarries in the county and provides the parameters for the requisite conditional district zoning.
 We hold a Synthetic Minor Construction and Operation Permit issued by the NCDEQ's Division of Air Quality for our property in Kings Mountain, North Carolina. In June 2022, we submitted an application to modify the active air permit to incorporate the use of Metso's pressure leach technology; however, in March 2024, we withdrew the modification application and continue to hold the air permit in its original form. We currently intend to sell this property since it is not strategic for the development of the Carolina Lithium project.
 In January 2022, we submitted a determination request to NCDEQ's Division of Air Quality in connection with Carolina Lithium. In March 2022, we received a response to this request informing us that Carolina Lithium would require a Title V Permit. In August 2022, we submitted our Title V Permit application, which was deemed complete in February 2023 and is subject to ongoing review.
 We previously worked with the NCDEQ Division of Water Resources on a National Pollutant Discharge Elimination System permit for the site; however, we recently pivoted toward pursuit of North Carolina General Stormwater permits instead. As a result, we have withdrawn our National Pollutant Discharge Elimination System permit applications and submitted applications required to obtain North Carolina General Stormwater permits for both the conversion plant as well as the mine and concentrator operations.

 Exploration and evaluation activities for our Carolina Lithium project included drilling, which was authorized under a general stormwater permit initially approved in 2017 by the NCDEQ and updated in April 2019, October 2019, and June 2021. We have reclamation obligations under this permit requiring us to reclaim all disturbed drill pads and temporary roads to the approximate original contours, including the seeding of grass and straw to stabilize any disturbances. Generally, we are required to affect such reclamation within 14 days following drilling. We have concluded that this cost of reclamation obligations is immaterial.
 We may be required to obtain additional permits and approvals for Carolina Lithium, including but not limited to, a municipal wastewater permit by the City of Gastonia Wastewater Treatment, a road abandonment approved by the NCDOT and Gaston County under North Carolina General Statute 136-63, an encroachment permit for an at-grade rail crossing issued by the NCDOT, various driveway permits issued by the NCDOT, a Gaston County Watershed Permit approved by the Gaston County Planning Department, various building permits approved by the Gaston County Planning Department, explosives permits approved by the U.S. Bureau of Alcohol, Tobacco, and Firearms, and hazardous chemical permits issued by Gaston County Fire Officials.
 U.S. Federal Legal Framework
 Carolina Lithium will be required to comply with applicable environmental protection laws and regulations and licensing and permitting requirements. The material environmental, health, and safety laws and regulations that we must comply with include, among others, the following U.S. federal laws and regulations:
 • NEPA, which requires careful evaluation of the environmental impacts of mining and lithium manufacturing operations that require federal approvals;
 • Clean Air Act and its amendments, which govern air emissions;
 • CWA, which governs discharges to and excavations within the waters of the U.S.;
 • RCRA, which governs the management of solid waste;
 • CERCLA, which imposes liability where hazardous substances have been released into the environment (commonly known as Superfund); and
 • Federal Mine Safety and Health Act, which established the primary safety and health standards regarding working conditions of employees engaged in mining, related operations, and preparation and milling of the minerals extracted, as well as the Occupation Safety and Health Act, which regulates the protection of the health and safety of workers in lithium manufacturing operations.
 Our operations will also be subject to state environmental laws and regulations, including but not limited to, laws and regulations related to the reclamation of mined lands, which may require reclamation bonds to be acquired prior to the commencement of mining operations and may require substantial financial guarantees to cover the cost of future reclamation activities.
 Solid and Hazardous Waste
 RCRA, and comparable state statutes, affect our operations by imposing regulations on the generation, transportation, treatment, storage, disposal, and cleanup of hazardous wastes and on the disposal of non-hazardous wastes. Under the auspices of the EPA, individual states administer some or all of the provisions of RCRA, sometimes in conjunction with their own, more stringent requirements.
 In addition, CERCLA can impose joint and several liability without regard to fault or legality of conduct on classes of persons who are statutorily responsible for the release of a hazardous substance into the environment. These persons can include the current and former owners, lessees, or operators of a site where a release occurs, and anyone who disposes or arranges for the disposal of a hazardous substance. Under CERCLA, such persons may be subject to strict, joint, and several liability for the entire cost of cleaning up hazardous substances that have been released into the environment and for other costs, including response costs, alternative water supplies, damage to natural resources and for the costs of certain health studies. Moreover, it is not uncommon for neighboring landowners, workers, and other third parties to file claims for personal injury and property damage allegedly caused by hazardous substances released into the indoor or outdoor environment. Each state also has environmental cleanup laws analogous to CERCLA. Hazardous wastes may have been previously handled, disposed of, or released on or under properties currently or formerly owned or leased by us or on or under other locations to which we sent waste for disposal. These properties and any materials disposed or released on them may subject us to liability under CERCLA, RCRA, and analogous state laws. Under such laws, we could be required to remove or remediate disposed wastes or property contamination, contribute to remediation costs, and perform remedial activities to prevent future environmental harm.

 Air Emissions
 The federal Clean Air Act and comparable state laws restrict the emission of air pollutants from numerous sources through the issuance of permits and the imposition of other requirements. Major sources of air pollutants are subject to more stringent, federally imposed permitting requirements. Air pollution regulations may require us to obtain pre-approval for the construction or modification of certain projects or facilities expected to produce or significantly increase air emissions, obtain air permits, and comply with stringent permit requirements or utilize specific equipment or technologies to control emissions of certain pollutants. The need to obtain permits has the potential to delay our operations, and we may be required to incur capital expenditures for air pollution control equipment or other air emissions related obligations. Administrative enforcement actions for failure to strictly comply with air pollution regulations or permits are generally resolved by payment of monetary fines and correction of any identified deficiencies. Alternatively, regulatory agencies could require us to forego construction, modification, or operation of certain air emission sources.
 Clean Water Act
 The CWA imposes restrictions and strict controls regarding the pollution of protected waters, including mineral processing wastes, into waters of the U.S., a term broadly defined to include, among other things, certain wetlands. Permits must be obtained to discharge pollutants into federal waters. The CWA provides for civil, criminal, and administrative penalties for unauthorized discharges, both routine and accidental, of pollutants. It imposes substantial potential liability for the costs of removal or remediation associated with discharges of oil or hazardous substances. State laws governing discharges to water also provide varying civil, criminal, and administrative penalties, and impose liabilities in the case of a discharge of petroleum or its derivatives, or other hazardous substances, into state waters. In addition, the EPA has promulgated regulations that require permits to discharge storm water runoff, including discharges associated with construction activities. In the event of an unauthorized discharge of waste, we may be liable for penalties and costs.
 Pursuant to these laws and regulations, we may also be required to develop and implement spill prevention, control, and countermeasure plans in connection with on-site storage of significant quantities of oil. Some states also maintain groundwater protection programs that require permits for discharges or operations that may impact groundwater conditions. The CWA also prohibits the discharge of fill materials to regulated waters, including wetlands, without a permit from the U.S. Army Corps of Engineers.
 In May 2015, the EPA issued a final rule that attempted to clarify the federal jurisdictional reach over waters of the U.S. The EPA repealed this rule in September 2019 and replaced it in April 2020 with the Navigable Water Protection Rule, which narrowed federal jurisdictional reach relative to the 2015 rule. The repeal and replacement of the 2015 rule is currently subject to litigation, and the scope of the jurisdictional reach of the CWA may, therefore, remain uncertain for several years, with a patchwork of legal guidelines applicable to various states potentially developing. We could incur increased costs and delays with respect to obtaining permits for dredge and fill activities in wetland areas to the extent they are required.
 NEPA
 NEPA requires federal agencies to evaluate major agency actions having the potential to significantly impact the environment. The NEPA process involves public input through comments, which can alter the nature of a proposed project either by limiting the scope of the project or requiring resource-specific mitigation. NEPA decisions can be appealed through the court system by process participants. This process may result in delaying the permitting and development of projects or increase the costs of permitting and developing some facilities.
 Endangered Species Act
 The federal Endangered Species Act restricts activities that may affect endangered and threatened species or their habitats. Some of our operations may be located in areas that are designated as habitats for endangered or threatened species. A critical habitat designation could result in further material restrictions to federal and private land use and could delay or prohibit land access or development. The U.S. Fish and Wildlife Service continues its effort to make listing decisions and critical habitat designations where necessary. To date, the Endangered Species Act has not had a significant impact on our operations. However, the designation of previously unprotected species as being endangered or threatened could cause us to incur additional costs or become subject to operating restrictions in areas where the species are known to exist.

 Foreign Legal Framework
 Our projects with Sayona Mining, Atlantic Lithium, and Vinland Lithium are required to comply with all environmental laws and regulations in Quebec, Canada, Ghana, West Africa, and Newfoundland, Canada, respectively.
 U.S. Foreign Corrupt Practices Act
 The U.S. FCPA generally prohibits U.S. companies and their intermediaries from making corrupt payments to foreign officials for the purpose of obtaining or keeping business or otherwise obtaining favorable treatment and requires companies to maintain appropriate record-keeping and internal accounting practices to accurately reflect the transactions of the company. The FCPA applies to companies, individual directors, officers, employees and agents. Under the FCPA, U.S. companies may be held liable for actions taken by agents or local partners or representatives. If we or our intermediaries fail to comply with the requirements of the FCPA or the anti-corruption laws of other countries, governmental authorities in the U.S. or other countries could seek to impose civil and criminal penalties, which could have a material adverse effect on our business.

We caution readers not to place undue reliance on any such forward-looking statements, which speak

 only as of the date made. Except as otherwise required by the securities laws of the U.S., we disclaim any obligation to subsequently revise any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events. We qualify all the forward-looking statements contained in this Annual Report by the foregoing cautionary statements.

 CAUTIONARY NOTE REGARDING DISCLOSURE OF MINERAL PROPERTIES
 We are subject to the periodic reporting requirements of both U.S. and Australian securities laws with respect to mining matters. In the U.S., we are governed by the Exchange Act, including S-K 1300 thereunder. In Australia, we are governed by the JORC Code. Both sets of reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported but may at times embody different approaches or definitions.
 On October 21, 2021, we announced an inaugural mineral resources estimate for our Carolina Lithium project. On December 14, 2021, we announced the completion of a DFS for our Carolina Lithium project, which included an initial estimation of mineral reserves. These estimates of mineral resources and mineral reserves are compatible with both S-K 1300 and JORC Code. A technical report summary with respect to our estimated mineral reserves was filed as an exhibit to our Transition Report on Form 10-KT for the period ending December 31, 2021. This technical report summary was amended to include certain information as required by S-K 1300. The amended technical report summary dated April 20, 2023, is included as Exhibit 96.1 and incorporated by reference to Exhibit 96.3 to our Annual Report on Form 10-K/A for the year ended December 31, 2022. Additionally, S-K 1300-compliant technical report summaries with respect to our estimated mineral resources and mineral reserves at NAL, and Authier, are attached as Exhibits 96.3 and 96.2, respectively, of this Annual Report.

 Item 1A. RISK FACTORS.
 You should carefully consider the risks, as described below, together with all the other information in this Annual Report. If any of the following risks occur, our business, financial condition, and results of operations could be seriously harmed, and you could lose all or part of your investment. Further, if we fail to meet the expectations of the public market in any given period, the market price of our common stock could decline. We operate in a competitive environment that involves significant risks and uncertainties, some of which are outside of our control. If any of these risks actually occurs, our business and financial condition could suffer, and the price of our stock could decline. We caution you that the risks, uncertainties and other factors referred to below and elsewhere in this Annual Report may not contain all the risks, uncertainties, and other factors that may affect our future results and operations. Our future results and operations could also be affected by factors, events, or uncertainties that are not presently known to us or that we currently do not consider to present a material risk. It is not possible for our management to predict all risks.
 Business Risks
 Our future performance is difficult to evaluate because we have a limited operating history in the lithium industry.
 We began to implement our current business strategy in the lithium industry in 2016. Until the third quarter of 2023, we had yet to realize any revenues from the sale of lithium, and our operating cash flow needs have been financed primarily through issuances of common stock and not through cash flows derived from our operations. As a result, we have limited historical financial and operating information available to help you evaluate our performance.
 There is no guarantee that our development will result in the commercial extraction of mineral deposits.
 We are engaged in the business of exploring and developing mineral properties with the intention of locating economic deposits of minerals. We have declared mineral reserves on our development stage properties; however, we have yet to begin commercial extraction of minerals on these properties. Accordingly, we cannot assure you that we will realize profits in the medium to long term. Further, we cannot assure you that any of our property interests can be commercially mined or that our ongoing exploration programs will result in profitable commercial mining operations. The exploration and development of mineral deposits involve a high degree of financial risk over a significant period of time, which may or may not be reduced or eliminated through a combination of careful evaluation, experience, and skilled management. While discovery of additional ore-bearing deposits may result in substantial rewards, few properties that are explored are ultimately developed into producing mines. Major expenses may be required to construct mining and processing facilities and to establish additional reserves. The profitability of our operations will be, in part, directly related to the cost and success of our exploration and development programs, which may be affected by a number of factors. Additional expenditures are required to construct, complete, and install mining and processing facilities in those properties that are actually mined and developed.

 Our exploration and development projects have no operating history upon which to base estimates of future operating costs and capital requirements. Exploration project items, such as any future estimates of reserves, metal recoveries, or cash operating costs will, to a large extent, be based upon the interpretation of geologic data, obtained from a limited number of drill holes and other sampling techniques as well as future feasibility studies. Actual operating costs and economic returns of any and all exploration projects may materially differ from the costs and returns estimated, and accordingly, our financial condition, results of operations, and cash flows may be negatively affected.
 We do not control our equity method investments.
 We apply the equity method of accounting to investments when we have the ability to exercise significant influence over the operational decision-making authority and financial policies of the investee but we do not exercise control. Our equity method investees are governed by their own board of directors, whose members have fiduciary duties to the investees' shareholders. While we have certain rights to appoint representatives to the investees' boards of directors, the interests of the investees' shareholders may not align with our interests or the interests of our shareholders and strategic and contractual disputes may arise.
 We are generally dependent on the management team of our investees to operate and control such projects or businesses. While we may exert influence pursuant to our positions, as applicable, on the boards of directors and through certain limited governance or oversight roles, such influence may be limited. The management teams of our investees may not have the level of experience, technical expertise, human resources, management, and other attributes necessary to operate their projects or businesses optimally, and they may not share our business priorities, including, but not limited to, those priorities that relate to desired production levels. This could have a material adverse effect on the value of such investments as well as our growth, business, financial condition, results of operations, and prospects.
 Some of our current or future properties may not contain any reserves, and any funds spent on exploration and evaluation may be lost.
 We are a development stage mining company. We cannot assure you that our exploration programs will identify economically extractable mineralization, nor can we assure you about the quantity or grade of any mineralization we seek to extract. Our exploration prospects may not contain any reserves and any funds spent on evaluation and exploration may be lost. Even for the mineral reserves we have reported for our properties, any quantity or grade of reserves we indicate must be considered as estimates only until such reserves are actually mined. We do not know with certainty that economically recoverable lithium exists on our properties. In addition, the quantity of any reserves may vary depending on commodity prices. Any material change in the quantity or grade of reserves may affect the economic viability of our properties.
 We face risks related to mining, exploration, mine construction, and plant construction, if warranted, on our properties.
 Our level of profitability, if any, in future years will depend to a great degree on lithium prices and whether our exploration-stage properties can be brought into production. Exploration and development of lithium resources are highly speculative in nature, and it is impossible to ensure that current and future exploration programs and/or feasibility studies on our existing properties will establish reserves. Whether it will be economically feasible to extract lithium depends on a number of factors, including, but not limited to: the particular attributes of the deposit such as size, grade, and proximity to infrastructure; lithium prices; mining, processing and transportation costs; the willingness of lenders and investors to provide project financing; labor costs and possible labor strikes; and governmental regulations, including, without limitation, regulations related to prices, taxes, royalties, land tenure, land use, importing and exporting materials, foreign exchange, environmental protection, employment, worker safety, transportation, and reclamation and closure obligations. We could be adversely affected by a failure to complete our plant construction projects on time or on budget, and a substantial delay in the progress of construction due to adverse weather, work stoppages, shortages of materials, non-issuances of permits, nonperformance of suppliers or contractors, or other factors could result in a material increase in the overall cost of such projects. The exact effect of these factors cannot be accurately predicted, but the combination of these factors may result in us receiving an inadequate return on invested capital. In addition, we are subject to the risks normally encountered in the mining industry, such as:
 • the discovery of unusual or unexpected geological formations;
 • accidental fires, floods, earthquakes, severe weather, or other natural disasters;
 • unplanned power outages and water shortages;
 • construction delays and higher than expected capital costs due to, among other things, supply chain disruptions, higher transportation costs, and inflation;
 • controlling water and other similar mining hazards;
 • explosions and mechanical failure of equipment;
 • operating labor disruptions and labor disputes;
 • shortages in materials or equipment and energy and electrical power supply interruptions or rationing;

 • seismic activity;
 • the ability to obtain suitable or adequate machinery, equipment, or labor;
 • our liability for pollution or other hazards; and
 • other unknown risks involved in the conduct of exploration and operation of mines.
 The nature of these risks is such that liabilities could exceed any applicable insurance policy limits or could be excluded from coverage. There are also risks against which we cannot insure or we may elect not to insure. The potential costs, which could be associated with any liabilities not covered by insurance or in excess of insurance coverage, or compliance with applicable laws and regulations may cause substantial delays and require significant capital outlays, adversely affecting our future earnings, competitive position, and potentially our financial viability.
 Our long-term success will depend ultimately on our ability to generate revenues, achieve and maintain profitability, and develop positive cash flows from our mining activities.
 Our ability to recover carrying values of our assets, acquire additional lithium projects, continue with exploration, development, commissioning, and mining, and manufacture lithium hydroxide ultimately depends on our ability to generate revenues, achieve and maintain profitability, and generate positive cash flow from our operations. The economic viability of our future mining activities has many risks and uncertainties, including, but not limited to:
 • a significant, prolonged decrease in the market price of lithium or lithium hydroxide;
 • difficulty in marketing and/or selling lithium or lithium hydroxide;
 • significantly higher than expected capital costs to construct our mine or production facilities;
 • significantly higher than expected extraction costs;
 • significantly lower than expected lithium extraction;
 • significant delays, reductions, or stoppages of lithium extraction activities;
 • shortages of adequate and skilled labor or a significant increase in labor costs;
 • the introduction of significantly more stringent regulatory laws and regulations; and
 • delays in the availability of construction equipment.
 We are concurrently overseeing the advancement of Carolina Lithium, which is in the development planning stage. Work to advance this project requires the dedication of considerable time and resources by us and our management team. The advancement of several major resource projects concurrently brings with it the associated risk of strains on managerial, human, and other resources. Our ability to successfully manage each of these processes will depend on a number of factors, including, but not limited to, our ability to manage competing demands on time and other resources, financial or otherwise, and successfully retain personnel and recruit new personnel to support our growth and the advancement of our projects.
 Our plan is to produce battery-grade lithium hydroxide from spodumene concentrate at Carolina Lithium using the innovative Metso pressure leach technology as well as a number of processes commonly used in the lithium industry today. We may encounter difficulties or unforeseen expenditures in integrating new, unproven technologies.
 It is common for a new mining operation to experience unexpected costs, problems, and delays during construction, commissioning, and mine start-up. Most mining projects suffer delays during these periods due to numerous factors, including the factors listed above. Any of these factors could result in changes to economic returns or cash flow estimates of the project or have other negative impacts on our financial position. There is no assurance that our projects will commence commercial production on schedule, or at all, or will result in profitable mining operations. If we are unable to develop our projects into a commercial operating mine, our business and financial condition will be materially adversely affected. Moreover, even if the feasibility study continues to support a commercially viable project, there are many additional factors that could impact the project's development, including terms and availability of financing, cost overruns, litigation or administrative appeals concerning the project, delays in development, and any permitting changes, among other factors.
 Our future mining and lithium manufacturing activities may change as a result of any one or more of these risks and uncertainties. We cannot assure you that any ore body from which we extract mineralized materials will result in achieving and maintaining profitability and developing positive cash flows.
 Our business is subject to cybersecurity risks.
 Our operations depend on effective and secure information technology systems. Threats to information technology systems, such as cyberattacks and cyber incidents, continue to increase. Cybersecurity risks include, but are not limited to, malicious software, attempts to gain unauthorized access to our data and the unauthorized release, corruption or loss of our data and personal information, as well as interruptions in communication and operations.

 It is possible that our business, financial, and other systems could be compromised, which could go unnoticed for a prolonged period of time. We have not experienced a material breach of our information technologies. Nevertheless, we continue to take steps to mitigate these risks by employing a variety of measures, including employee training, technical security controls, and maintenance of backup and protective systems. Despite these mitigation efforts, cybersecurity attacks and other threats exist and continue to increase, any of which could have a material adverse effect on our business, results of operations, financial condition, and cash flows.
 Our long-term success depends on our ability to enter into and deliver product under offtake agreements.
 We may encounter difficulty entering and fulfilling offtake agreements for our products. We may fail to deliver the product required by such agreements or may experience production costs in excess of the price to be paid to us under such agreements. Failure to meet these specifications could result in price adjustments, the rejection of deliveries, or termination of the contracts. Our supply agreements contain force majeure provisions allowing temporary suspension of performance by us or the customer during specified events beyond the control of the affected party. As a result of these issues, we may not achieve the revenue or profit we expect to achieve from our offtake agreements. As of the date of this filing, we have entered into two offtake agreements for our lithium products.
 On August 30, 2024, we entered into an amended offtake agreement with Tesla, Inc. to provide spodumene concentrate from NAL in Quebec. The agreement commits us to sell 125,000 dmt of spodumene concentrate from our offtake agreement with Sayona Quebec. The term of the agreement runs through September 2026, and pricing is determined by a market-based mechanism. The initial term can be extended for an additional three years upon mutual agreement.
 On February 16, 2023, we entered into a spodumene concentrate offtake agreement with LG Chem, which commits us to sell 200,000 dmt of spodumene concentrate from our offtake agreement with Sayona Quebec. The term of the agreement ends in the second quarter of 2028 or upon Piedmont delivering 200,000 dmt of spodumene concentrate. Pricing is determined by a market-based mechanism.
 Our business, results of operations, and financial condition may be materially and adversely affected if we are unable to enter into similar agreements with other buyers, deliver the products required by such agreements, or incur costs in excess of the price set forth in such agreements.
 We depend on our ability to successfully access the capital and financial markets. Any inability to access the capital or financial markets may limit our ability to meet our liquidity needs and long-term commitments, fund our ongoing operations, execute our business plan or pursue investments that we may rely on for future growth.
 We may continue to incur operating and investing net cash outflows associated with, but not limited to, maintaining and acquiring exploration properties, undertaking ongoing exploration activities, the development of our planned projects, and our funding obligations to develop the assets of our joint ventures with Sayona Mining, including NAL, and Atlantic Lithium's Ewoyaa project. As a result, we rely on access to capital markets as a source of funding for our capital and operating requirements. We will require additional capital to meet our liquidity needs related to expenses for our various corporate activities, including costs related to our status as a publicly traded company, funding of our ongoing operations, exploring and defining lithium mineralization, and establishing any future mining or lithium manufacturing operations. We cannot assure you that such additional funding will be available to us on satisfactory terms, or at all.
 To finance our future ongoing operations and future capital needs, we may require additional funds through the issuance of additional equity or debt securities. Depending on the type and terms of any financing we pursue, stockholders' rights and the value of their investment in our common stock could be reduced. Any additional equity financing will dilute shareholdings. If the issuance of new securities results in diminished rights to holders of our common stock, the market price of our common stock could be negatively impacted. New or additional debt financing, if available, may involve restrictions on financing and operating activities. In addition, if we issue secured debt securities, the holders of the debt would have a claim to our assets that would be prior to the rights of stockholders until the debt is paid. Interest on such debt securities would increase costs and negatively impact operating results.
 We have a universal shelf registration statement on file with the SEC to provide us with capacity to publicly offer common stock, preferred stock, warrants, debt, convertible or exchangeable securities, depositary shares, or units, or any combination thereof. We may, from time to time, raise capital under our shelf registration statement in amounts, at prices, and on terms to be announced when and if any securities are offered. As of December 31, 2024, we had $500.0 million remaining under our shelf registration statement, which expires on September 26, 2027.
 If we are unable to obtain additional financing, as needed, at competitive rates, our ability to fund our current operations and implement our business plan and strategy will be affected. These circumstances may require us to reduce the scope of our operations and scale back our exploration, development and mining programs. There is, however, no guarantee that we will be able to secure any

 additional funding or be able to secure funding to provide us with sufficient funds to meet our objectives, which may adversely affect our business and financial position. Certain market disruptions may increase our cost of borrowing or affect our ability to access one or more financial markets. Such market disruptions could result from, but are not limited to:
 • adverse economic conditions;
 • adverse general capital market conditions;
 • poor performance and health of the lithium or mining industries in general;
 • bankruptcy or financial distress of unrelated lithium companies or marketers;
 • significant decrease in the demand for lithium products;
 • significant decrease in the price of lithium products; or
 • adverse regulatory actions that affect our exploration and construction plans or the use of lithium generally.
 Our ability to manage growth will have an impact on our business, financial condition, and results of operations.
 Future growth may place strains on our financial, technical, operational, and administrative resources and cause us to rely more on project partners and independent contractors, thus, potentially adversely affecting our financial position and results of operations. Our ability to grow will depend on a number of factors, including, but not limited to:
 • our ability to purchase, obtain leases on, or obtain options on properties;
 • our ability to identify and acquire new exploratory prospects;
 • our ability to develop existing prospects;
 • our ability to continue to retain and attract skilled personnel;
 • our ability to maintain or enter into new relationships with project partners and independent contractors;
 • the results of our exploration programs;
 • the market price for lithium products;
 • our ability to successfully complete construction projects on schedule, and within budget;
 • our access to capital; and
 • our ability to enter into agreements for the sale of lithium products.
 We may not be successful in upgrading our technical, operational, and administrative resources or increasing our internal resources sufficiently to provide certain services currently provided by third parties. Our inability to achieve or manage growth may materially and adversely affect our business, results of operations, and financial condition.
 We may acquire additional businesses or assets, form joint ventures, or make investments in other companies that may be unsuccessful and harm our operating results and prospects.
 As part of our business strategy, we may pursue additional acquisitions of complementary businesses or assets or seek to enter into joint ventures. We may pursue strategic alliances, such as our Sayona Mining, Atlantic Lithium, and Vinland Lithium investments, in an effort to leverage our existing operations and industry experience, increase our product offerings, expand our distribution, and make investments in other companies.
 The success of any acquisitions, joint ventures, strategic alliances, or investments, including our Sayona Quebec, Atlantic Lithium, and Vinland Lithium investments, will depend on our ability to identify, negotiate, complete and, in the case of acquisitions, integrate those transactions and, if necessary, obtain satisfactory debt or equity financing to fund those transactions. We may not realize the anticipated benefits of any acquisition, joint venture, strategic alliance or investment. We may not be able to integrate acquisitions successfully into our existing business, maintain the key business relationships of businesses we acquire, or retain key personnel of an acquired business. We could assume unknown or contingent liabilities or incur unanticipated expenses. Integration of acquired companies or businesses also may require management resources that otherwise would be available for ongoing development of our existing business. Any acquisitions or investments made by us could result in significant write-offs or the incurrence of debt and contingent liabilities, any of which could harm our operating results. If we choose to issue equity as consideration for any acquisition, our stockholders may experience dilution.
 We are dependent upon key management employees.
 The responsibility of overseeing the day-to-day operations and the strategic management of our business depends substantially on our senior management and key personnel. Loss of any such personnel may have an adverse effect on our performance. The success of our operations will depend upon numerous factors, many of which, in part, are beyond our control, including our ability to attract and retain additional key personnel in sales, marketing, technical support, and finance. Certain areas in which we operate are highly competitive and competition for qualified personnel is significant. We may be unable to hire suitable field personnel for our technical team or there may be periods of time where a particular position remains vacant while a suitable replacement is identified and appointed. We may not be successful in attracting and retaining the personnel required to grow and operate our business profitably.

 Our growth will require new personnel, which we will be required to recruit, hire, train, and retain.
 Members of our management team possess significant experience and have previously carried out or been exposed to exploration, development, and production activities. However, we have a limited operating history with respect to lithium projects and our ability to achieve our objectives depends on the ability of our directors, officers, and management to implement current plans and respond to any unforeseen circumstances that require changes to those plans. The execution of our exploration, development, and production plans will place demands on us and our management. Thus, our ability to recruit and assimilate new personnel will be critical to our performance. We will be required to recruit additional personnel and to train, motivate, and manage employees. Failure to meet these requirements may adversely affect our plans.
 Lawsuits may be filed against us and an adverse ruling in any such lawsuit may adversely affect our business, financial condition, or liquidity or the market price of our common stock.
 We may become involved in, named as a party to, or be the subject of various legal proceedings, including regulatory proceedings, tax proceedings, and legal actions related to personal injuries, property damage, property taxes, land rights, the environment, and contract disputes. For additional information, refer to Part I, Item 3, "Legal Proceedings."
 The outcome of outstanding, pending, or future proceedings cannot be predicted with certainty and may be determined adversely to us and as a result, could have a material adverse effect on our assets, liabilities, business, financial condition, or results of operations. Even if we prevail in any such legal proceeding, the proceedings could be costly, time-consuming, and may divert the attention of management and key personnel from our business operations, which could adversely affect our financial condition.
 Our mineral properties may be subject to defects in title.
 Title to the majority of our properties for Carolina Lithium are derived from option agreements with local landowners in North Carolina, which upon exercise, allow us to purchase, or in certain cases, long-term lease the real property and associated mineral rights from the local landowners. If we exercise the option to purchase a property, we will pay cash consideration, approximating the fair market value of the real property, excluding the value of any minerals, plus a premium based on a negotiated fixed price or percentage premium. If we exercise the option for a long-term lease, we will pay annual advanced royalty payments per acre. Some landowners also retain a production royalty payable on production of ore from the property.
 The ownership and title to unpatented mining claims and concessions are often uncertain and may be contested. We may not have, or may not be able to obtain, all necessary rights to develop a property. Although we have obtained title opinions with respect to certain of our properties and have taken reasonable measures to ensure proper title to our properties, there is no guarantee that title to any of our properties will not be challenged or impugned. Title insurance is generally not available for mineral properties and our ability to ensure that we have obtained clear title to individual mineral properties or mining concessions may be severely constrained. Our mineral properties may be subject to prior unregistered agreements, transfers, or claims, and title may be affected by, among other things, undetected defects. We may incur significant costs related to defending the title to our properties. A successful claim contesting our title to a property may cause us to compensate other persons or perhaps reduce our interest in the affected property or lose our rights to explore and develop that property. This could result in our not being compensated for our prior expenditures related to the property. In any such case, the investigation and resolution of title issues would divert our management's time from ongoing exploration and, if warranted, development programs. Any impairment or defect in title could negatively affect us.
 Our directors and officers may be in a position of conflict of interest.
 Some of our directors and officers currently serve as directors and officers of other companies involved in natural resource exploration, development, and production, and any of our directors and officers may serve in such positions in the future. As of the date of this Annual Report, none of our directors or officers serves as an officer or director of a lithium exploration, development, or producing company nor possess a conflict of interests with our business, other than as follows: (i) pursuant to our agreements related to our Sayona Mining investment, Keith Phillips, our President and Chief Executive Officer, was appointed as a board member of Sayona Quebec, and (ii) pursuant to our agreements related to our Vinland Lithium investment, Mr. Czachor was appointed as a board member of Vinland Lithium. However, there exists the possibility that they may be in a position of conflict of interest in the future. Any decision made by such persons involving us will be made in accordance with their duties and obligations to deal fairly and in good faith with us and such other companies. In addition, any such directors and officers will declare, and refrain from voting on, any matter in which such directors and officers may have a material interest.
 In order to manage our growth effectively and support our future operations, we expect to improve our financial and operations systems.
 To manage our growth and support our future manufacturing operations, we will periodically upgrade our operational and financial systems and procedures. This requires management time and may result in significant expense. We cannot be certain that we will

 institute in a timely or efficient manner, or at all, the improvements to our managerial, operational, and financial systems and procedures necessary to support our anticipated increased levels of operations. Problems associated with, or disruptions resulting from, any improvement or expansion of our operational and financial systems could adversely affect our relationships with our suppliers and customers, inhibit our ability to expand or take advantage of market opportunities, cause harm to our reputation, result in errors in our financial and other reporting, and adversely affect our ability to maintain an effective internal control environment and meet our external reporting obligations, any of which could harm our business and operating results and affect our stock price.
 There is no assurance we will secure a loan from the Department of Energy's Loan Programs Office.
 We previously received a conditional invitation from the DOE to due diligence for an ATVM loan for our Carolina Lithium project. As our Carolina Lithium project has not yet met the conditional criteria for the Loan Programs Office to start due diligence, we withdrew our application in 2023 with the intention to resubmit an application at a future date and remain in the pre-application stage of the ATVM loan process. If and when we submit an application for an ATVM loan, the Loan Programs Office must make a finding that Carolina Lithium is eligible and meets the viability thresholds specified under law. Thereafter, our application becomes subject to both preliminary and advanced-stage due diligence and the negotiation of preliminary terms and conditions. Should the Loan Programs Office issue a conditional commitment letter for either project, and should we satisfy all conditions precedent and requirements specified in the letter, we would become eligible to enter into a final loan agreement. Upon closing, the loan would remain subject to certain restrictive covenants and financial reporting requirements set forth in the final loan agreement. As a result, there can be no assurance that we will secure such loan from the DOE for the project within the expected timeframe, on terms that are acceptable to the Company, or at all.
 We are dependent on a limited number of customers, which makes us vulnerable to the continued relationship with and financial health of those customers.
 Four customers have accounted for 100% of our revenue as of the date of this Annual Report. Our future prospects may depend on the continued business of a limited number of key customers and on our continued status as a qualified supplier to such customers. We cannot guarantee that these key customers will continue to buy products from us at current levels. The loss of a key customer could have a material adverse effect on our business, financial condition, and results of operations.
 If we are required to register as an investment company, we will be subject to a significant regulatory burden and our results of operations will suffer.
 We are an operating company and believe we are not subject to regulation as an investment company under the U.S. Investment Company Act of 1940, as amended. However, if we were required to register as an investment company, our ability to use debt would be substantially reduced, and we would be subject to significant additional disclosure obligations and restrictions on our operational activities. Because of the additional requirements imposed on an investment company with regard to the distribution of earnings, operational activities and the use of debt, in addition to increased expenditures due to additional reporting responsibilities, our cash available for investments would be reduced. The additional expenses would reduce income. These factors would adversely affect our business, financial condition, and the results of operations and cash flows.
 Risks Related to the Merger Agreement
 The completion of the Merger Agreement is subject to a number of conditions and the Merger Agreement may be terminated in accordance with its terms. As a result, the timing surrounding the closing of the Merger Agreement is uncertain and there is risk that the Merger may not be completed.
 The completion of the Merger is subject to the satisfaction or waiver of a number of conditions as set forth in the Merger Agreement, including, among others: (1) requisite approvals of Piedmont's stockholders and Sayona's shareholders of the Merger Agreement, (2) required regulatory approvals (including expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended), (3) the absence of certain enumerated legal impediments to the consummation of the Merger, (4) effectiveness of the registration statement for the Sayona Mining Ordinary Shares and Sayona Mining ADSs to be issued as consideration in the Merger and the related Form F-6, (5) the authorization to list the Sayona Mining ADSs and Sayona Mining Ordinary Shares issuable pursuant to the Merger Agreement on the Nasdaq and the ASX, respectively, (6) required approvals from ASX and the Australian Securities and Investments Commission, (7) the representations and warranties of each of Piedmont and Sayona Mining being true and correct to the extent required by, and subject to the applicable materiality standards set forth in, the Merger Agreement; each of Piedmont, Sayona Mining and the other parties to the Merger Agreement having in all material respects performed the obligations and complied with the covenants required to be performed or complied with by it under the Merger Agreement, and (8) there having been no material adverse effect (as defined in the Merger Agreement) with respect to Piedmont or Sayona Mining. The timing surrounding whether these conditions will be satisfied or waived, if at all, is uncertain. Additionally, other events could intervene to delay or result in the failure to close the Merger.

 If completion of the Merger has not occurred by September 30, 2025, either Piedmont or Sayona Mining may choose to terminate the Merger Agreement. However, this right to terminate the Merger Agreement will not be available to Piedmont or Sayona Mining if such party has failed to fulfill any material covenant or agreement under the Merger Agreement and such failure has been the cause of, materially contributed to, or resulted in the failure of the Merger to occur on or before such date. Piedmont or Sayona Mining may elect to terminate the Merger Agreement in certain other circumstances, including if the Sayona Mining shareholders or Piedmont's stockholders fail to approve the Merger at the respective shareholder meetings, and Piedmont and Sayona Mining can mutually decide to terminate the Merger Agreement at any time prior to the effective time of the Merger, before or after the required approval by the Sayona Mining shareholders or Piedmont stockholders.
 The completion of the Merger is subject to risks and uncertainties surrounding conditions that may be imposed by regulatory or governmental entities which may reduce the anticipated benefits of the Merger or could prevent the closing of the Merger entirely.
 Regulatory and governmental entities may impose conditions on the granting of consents required in connection with the Merger. The conditions imposed by regulatory and governmental entities on the granting of authorizations, consents, orders and approvals may require divestitures of certain divisions, operations or assets of Piedmont or Sayona Mining and may impose costs, limitations or other restrictions on business conduct. Under the Merger Agreement, each of Piedmont and Sayona Mining has agreed to use reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, and to assist and cooperate with the other in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner reasonably practicable, the Merger. However, neither party shall be required to become subject to, consent to, or offer or agree to, or otherwise take any action with respect to, any requirement, condition, limitation, understanding, agreement or order to (1) sell or otherwise dispose of, or hold separate and agree to sell or otherwise dispose of, assets, categories of assets or businesses of Piedmont or Sayona Mining, (2) terminate, modify or extend any existing relationships and contractual rights and obligations of Piedmont, Sayona Mining or their respective subsidiaries, (3) terminate any relevant venture or other arrangement, (4) effectuate any other change or restructuring of Piedmont, Sayona Mining or their respective subsidiaries (and, in each case, to enter into agreements or stipulate to the entry of an order or file appropriate applications with any governmental entity), or (5) litigate (or defend) against any administrative or judicial action or proceeding (including any proceeding seeking a temporary restraining order or preliminary injunction) challenging any of the transactions contemplated by the Merger Agreement as violative of any applicable national security law.
 Compliance with any conditions imposed by regulatory and governmental entities may reduce the anticipated benefits of the Merger, which could also have an adverse effect on the business, cash flows and results of operations, and neither Piedmont nor Sayona Mining can predict what, if any, changes may be required by regulatory or governmental authorities whose consents, orders or approvals are required.
 The termination of the Merger Agreement could negatively impact us and, in certain circumstances, could require us to pay a termination fee to Sayona.
 If the Merger Agreement is terminated in accordance with its terms and the Merger is not completed, our ongoing business may be adversely affected by a variety of factors, including the failure to pursue other beneficial opportunities during the pendency of the Merger, the failure to obtain the anticipated benefits of completing the Merger, the payment of certain costs relating to the Merger and the focus of our management on the Merger for an extended period of time rather than on ongoing business matters or other opportunities or issues. Our stock price may fall as a result of any such termination, to the extent that the current price of our shares reflects a market assumption that the Merger will be completed (although this is difficult to predict with any certainty). In addition, the failure to complete the Merger may result in negative publicity or a negative impression of Piedmont in the investment community and may affect our relationship with employees, customers, suppliers, vendors and other partners.
 We may be required to pay Sayona Mining a termination fee equal to $2.62 million if the Merger Agreement is terminated under certain circumstances specified in the Merger Agreement relating to, among other things, if Piedmont's Board changes its recommendation that Piedmont stockholders vote in favor of the Merger or if there is a willful and material breach of certain provisions of the Merger Agreement by Piedmont.
 Further, Piedmont will also be required to pay Sayona Mining the $2.62 million termination fee if the Merger Agreement is terminated under certain circumstances specified in the Merger Agreement after we receive a competing transaction proposal, and, within twelve months after the date of termination, we enter into a definitive agreement with respect to or consummate the competing transaction proposal. If the Merger Agreement is terminated and we determine to seek another business combination or strategic opportunity, we may not be able to negotiate a transaction with another party on terms comparable to, or better than, the terms of the Merger.

 The pendency of the Merger could adversely affect our and Sayona Mining's respective business, results of operations, and financial condition.
 The pendency of the Merger could cause disruptions in and create uncertainty surrounding Piedmont's and Sayona Mining's respective businesses, including by affecting relationships with Piedmont's and Sayona Mining's respective existing and future customers, suppliers, vendors, partners, and employees, and Piedmont's and Sayona Mining's respective standing with local communities, regulators, and other government officials. This could have an adverse effect on Piedmont's and Sayona Mining's respective businesses, results of operations and financial condition, as well as the market prices of Piedmont's shares and Sayona Mining's shares, regardless of whether the Merger is completed. In particular, Piedmont and Sayona Mining could potentially lose important personnel who decide to pursue other opportunities as a result of the Merger. Any adverse effect could be exacerbated by a prolonged delay in completing the Merger. Piedmont and Sayona Mining could also potentially lose customers, suppliers or vendors, existing customers, suppliers or vendors may seek to change their existing business relationships or renegotiate their contracts with Piedmont or Sayona Mining or defer decisions concerning Piedmont or Sayona Mining and potential customers, suppliers, or vendors could defer entering into contracts with Piedmont or Sayona Mining, each as a result of uncertainty relating to the Merger. In addition, in an effort to complete the Merger, Piedmont and Sayona Mining have expended, and will continue to expend, significant management resources on matters relating to the Merger, which are being diverted from Piedmont's and Sayona Mining's day-to-day operations, and significant demands are being, and will continue to be, placed on the managerial, operational and financial personnel and systems of Piedmont and Sayona Mining in connection with efforts to complete the Merger.
 While the Merger Agreement is in effect, Piedmont and Sayona Mining are subject to restrictions on their conduct and business activities, which could adversely affect both companies' business, financial results, financial condition or share price.
 Under the Merger Agreement, each of Piedmont and Sayona Mining is subject to a range of restrictions on the conduct of its respective business and generally must operate its business in the ordinary course of business consistent with past practice prior to completing the Merger. These restrictions may constrain Piedmont's and Sayona Mining's ability to pursue certain business strategies. The restrictions may also prevent Piedmont and Sayona Mining from pursuing otherwise attractive business opportunities, making acquisitions and investments or making other changes to our and its respective businesses prior to the completion of the Merger or the termination of the Merger Agreement. Any such lost opportunities may reduce either or both companies' competitiveness or efficiency and could lead to an adverse effect on their respective business, financial results, financial condition or share prices.
 The Merger Agreement contains restrictions on our ability to pursue alternatives to the Merger, which may limit the value that our stockholders could receive from a transaction.
 The Merger Agreement generally prohibits us, subject to certain exceptions, from initiating, soliciting, proposing, knowingly encouraging or otherwise knowingly facilitating any inquiries or the making of any proposal or offer that constitute or would reasonably be expected to lead to any competing transaction proposal. Further, subject to limited exceptions and consistent with applicable law, the Merger Agreement prohibits our Board from changing, withholding, withdrawing, qualifying or modifying, in a manner adverse to Sayona Mining, its recommendation that our stockholders approve the Merger and, in specified circumstances, Sayona Mining has a right to negotiate with us in order to match any competing transaction proposal that may be made. Although our Board is permitted to take certain actions in response to a superior transaction proposal or a competing transaction proposal that would reasonably be expected to result in a superior transaction proposal if it determines that the failure to do so would likely breach its statutory or fiduciary duties under applicable law, in specified situations, we may still be required to pay to Sayona Mining a termination fee of $2.62 million. These provisions may limit our ability to pursue offers from third parties that could result in greater value to our stockholders than they would receive in the Merger. The $2.62 million termination fee may also discourage third parties from pursuing an acquisition proposal with respect to Piedmont.
 Piedmont and Sayona Mining may be targets of shareholder class actions or derivative actions, which could result in substantial costs and may delay or prevent the Merger from being completed.
 Shareholder class action lawsuits or derivative lawsuits are often brought against companies that have entered into transaction agreements. Such litigation can be costly and time consuming and can create uncertainty. Even if the lawsuits are without merit, defending against these claims can result in substantial costs and divert management time and resources. Additionally, if a plaintiff is successful in obtaining an injunction prohibiting consummation of the Merger, then that injunction may delay or prevent the Merger from being completed. One of the conditions to consummating the Merger is that no governmental entity has issued any order, decree, ruling, injunction or other action that is in effect (whether temporary, preliminary or permanent) restraining, enjoining or otherwise prohibiting the consummation of the Merger. Consequently, if a party secures injunctive or other relief prohibiting, delaying or otherwise adversely affecting Piedmont's or Sayona Mining's ability to complete the Merger on the terms contemplated by the Merger Agreement, then such law or injunctive or other relief may prevent consummation of the Merger in a timely manner or at all. These lawsuits also have the potential to negatively impact Piedmont's or Sayona Mining's reputation.

 The combined company may not realize all of the anticipated benefits of the Merger.
 The combined company may not realize all of the anticipated benefits of the transaction. There is a risk that some or all of the expected benefits of the transaction may fail to materialize, or may not occur within the time periods anticipated by Sayona and Piedmont. The realization of such benefits may be affected by a number of factors, many of which are beyond the control of Sayona and Piedmont. The challenge of integrating previously independent businesses makes evaluating the business and future financial prospects of the combined company following the transaction difficult. Piedmont and Sayona have operated and, until completion of the transaction, will continue to operate, independently. The success of the transaction, including anticipated benefits and cost savings, will depend, in part, on the ability to successfully integrate the operations of both companies in a manner that results in various benefits, including, among other things, the expected optimization of NAL, currently owned 75% by Sayona and 25% by Piedmont, through consolidated offtake economics, complimentary technical capabilities, and material logistics, procurement and marketing synergies with aligned economic interests in pursuing NAL brownfield expansion. The past financial performance of each of Piedmont and Sayona may not be indicative of the future financial performance of the combined company. Piedmont and Sayona have incurred significant financial services, accounting, tax and legal fees in connection with the process of negotiating and evaluating the terms of the transaction. Additional significant unanticipated costs may be incurred in the course of coordinating the businesses of Piedmont and Sayona after completion of the transaction. Even if the transaction is not completed, Piedmont and Sayona will need to pay certain costs relating to the transaction incurred prior to the date the transaction was abandoned, such as financial advisory, accounting, tax, legal, filing and printing fees. Such costs may be significant and could have an adverse effect on the parties' future results of operations.
 Piedmont and Sayona Mining may have difficulty attracting, motivating and retaining executives and other employees in light of the Merger.
 Uncertainty about the effect of the Merger on current Piedmont employees and/or Sayona Mining employees may have an adverse effect on the combined company. This uncertainty may impair Piedmont's ability to attract, retain and motivate personnel until the Merger is completed. Employee retention may be particularly challenging during the pendency of the Merger, as employees may feel uncertain about their future roles with Piedmont after their combination. If large numbers of employees, or a concentration of critical employees of Piedmont, depart because of issues relating to the uncertainty or perceived difficulties of integration or a desire not to become employees of the combined company after the Merger, Piedmont's ability to realize the anticipated benefits of the Merger could be reduced.
 Piedmont will incur significant costs related to the Merger that could have a material adverse effect on its liquidity, cash flows and operating results.
 Piedmont expects to incur significant one-time costs in connection with the Merger. These costs have been, and will continue to be, substantial and, in many cases, will be borne by Piedmont whether or not the Merger is completed. A substantial majority of these one-time costs will be transaction-related fees and expenses and include, among others, fees paid to financial, legal, accounting and other professional fees and transition and pre-Merger integration planning-related expenses. While Piedmont expects to be able to fund these one-time costs using existing cash, these costs will negatively impact Piedmont's liquidity, cash flows and results of operations in the periods in which they are incurred.
 Regulatory and Industry Risks
 We will be required to obtain governmental permits and approvals in order to conduct development and mining operations, a process that is often costly and time-consuming. There is no certainty that all necessary permits and approvals for our planned operations will be granted.
 We are required to obtain and renew governmental permits and approvals for our exploration and development activities, and prior to mining any mineralization we discover, we will be required to obtain additional governmental permits and approvals that we do not currently possess. Obtaining and renewing any of these governmental permits is a complex, time-consuming, and uncertain process involving numerous jurisdictions, public hearings, and possibly costly undertakings. The timeliness and success of permitting efforts are contingent upon many variables not within our control, including the interpretation of approval requirements administered by the applicable governmental authority.
 We may not be able to obtain or renew permits or approvals that are necessary to our planned operations, or we may discover that the cost and time required to obtain or renew such permits and approvals exceeds our expectations. Any unexpected delays, costs or conditions associated with the governmental approval process could delay our planned exploration, development, and mining operations, which in turn could materially adversely affect our prospects, revenues, and profitability. In addition, our prospects may be adversely affected by the revocation or suspension of permits or by changes in the scope or conditions to use of any permits obtained.

 For example, in addition to the permits that we have been issued to date, we are required to obtain other permits and approvals before construction or operations of Carolina Lithium, including approvals related to rezoning, mining, mineral concentration, and chemical manufacturing. Such permits include an air permit that would be issued by the Division of Air Quality and rezoning that would be approved by the Gaston County Board of Commissioners. The following permits have been submitted for Carolina Lithium: (i) Prevention of Significant Deterioration Title V Air Permit to the Division of Air Quality on August 31, 2022, and (ii) North Carolina General Stormwater permits for both the conversion plant as well as the mine and concentrator operations.
 Private parties frequently attempt to intervene in the permitting process to persuade regulators to deny necessary permits or seek to overturn permits that have been issued. For example, on June 6, 2024, four petitioners with residential or business properties near our permitted Carolina Lithium project filed a Petition for a Contested Case Hearing with the North Carolina Office of Administrative Hearings, challenging DEMLR's issuance of our mining permit for Carolina Lithium. While the four petitioners voluntarily dismissed without prejudice all claims asserted under their petition on February 3, 2025, we cannot guarantee the petitioners will not attempt to refile the petition in the future. For more information, see Note 19—Commitments and Contingencies. Third-party actions like these can materially increase the costs, cause delays in the permitting process, and could cause us to not proceed with the development or operation of a property. Our ability to successfully obtain key permits and approvals to explore for, develop, operate, and expand operations will likely depend on our ability to undertake such activities in a manner consistent with the creation of social and economic benefits in the surrounding communities, which may or may not be required by law. Our ability to obtain permits and approvals and to successfully operate in particular communities may be adversely affected by real or perceived detrimental events associated with our activities.
 Certain members of the Gaston County Board have indicated opposition to granting the approvals necessary for Carolina Lithium. In September 2021, the Gaston County Board approved updates to the Gaston County Unified Development Ordinance, which in part, established certain operating limitations for new mines and quarries within the county and provides the parameters for requisite Conditional District zoning. While we have initiated a dialog with the Gaston County Board, we are unable to predict the duration, scope, result, or related costs or conditions associated with the Boards' review, nor can we assure you that we will be successful in obtaining required local approvals.
 Lithium and lithium byproduct prices are subject to unpredictable fluctuations which may greatly affect the value of our investment in our lithium assets and our ability to develop them successfully.
 The prices of lithium and lithium byproducts may fluctuate widely and are affected by numerous factors beyond our control, including international, economic, and political trends, expectations of inflation, currency exchange fluctuations, interest rates, global and regional consumptive patterns, speculative activities, increased production due to new extraction developments and improved extraction and production methods and technological changes in the markets for the end products. The effect of these factors on the prices of lithium and lithium byproducts, and therefore the economic viability of any of our exploration, development, and operational properties, cannot be accurately predicted and could have dramatic effects on the results of our operations and our ability to execute our business plan.
 New production of lithium hydroxide or lithium carbonate from current or new competitors in the lithium markets could adversely affect prices. In recent years, new and existing competitors have increased the supply of lithium hydroxide and lithium carbonate, which has affected pricing. Further production increases could negatively affect prices. There is limited information on the status of new lithium hydroxide production capacity expansion projects being developed by current and potential competitors and, as such, we cannot make accurate projections regarding the capacities of possible new entrants into the market and the dates on which they could become operational. If these potential projects are completed in the short term, they could adversely affect market lithium prices, thereby resulting in a material adverse effect on the economic feasibility of extracting any mineralization we discover and reducing or eliminating any reserves we identify.
 We may not be able to effectively mitigate pricing risks for our products. Depressed pricing for our products will affect the level of revenues expected to be generated by us, which, in turn, could affect our value, share price and the potential value of our assets. There can be no assurance that the price of lithium products will be such that it can be produced at a profit.
 The proposed Carolina Lithium project will be subject to significant governmental regulations, including the U.S. Federal Mine Safety and Health Act.
 Mining activities in the U.S. are subject to extensive foreign, federal, state, and local laws and regulations governing environmental protection, natural resources, prospecting, development, production, post-closure reclamation, taxes, labor standards, and occupational health and safety laws and regulations, including mine safety, toxic substances, and other matters. The costs associated with compliance with such laws and regulations are substantial. In addition, changes in such laws and regulations, or more restrictive

 interpretations of current laws and regulations by governmental authorities, could result in unanticipated capital expenditures, expenses, or restrictions on or suspensions of our operations and delays in the development of our properties.
 Compliance with environmental regulations and litigation based on environmental regulations could require significant expenditures.
 Environmental regulations mandate, among other things, the maintenance of air and water quality standards, land development, and land reclamation, and set forth limitations on the generation, transportation, storage, and disposal of solid and hazardous waste. Environmental legislation is evolving in a manner that may require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects, and a heightened degree of responsibility for mining companies and their officers, directors, and employees. In connection with our current exploration activities or in connection with our prior mining operations, we may incur environmental costs that could have a material adverse effect on the financial condition and results of our operations. Any failure to remedy an environmental problem could require us to suspend operations or enter into interim compliance measures pending completion of the required remedy.
 Moreover, governmental authorities and private parties may bring lawsuits based upon damage to property and injury to persons resulting from the environmental, health, and safety impacts of prior and current operations, including operations conducted by other mining companies many years ago at sites located on properties that we currently own or formerly owned. These lawsuits could lead to the imposition of substantial fines, remediation costs, penalties, and other civil and criminal sanctions as well as reputational harm, including damage to our relationships with customers, suppliers, investors, governments, or other stakeholders. Such laws, regulations, enforcement, or private claims may have a material adverse effect on our financial condition, results of operations, or cash flows.
 Changes in technology or other developments could adversely affect demand for lithium compounds or result in preferences for substitute products.
 Lithium and its derivatives are preferred raw materials for certain industrial applications, such as rechargeable batteries. For example, current and future high energy density batteries for use in electric vehicles will rely on lithium compounds as a critical input. The pace of advancements in current battery technologies, development and adoption of new battery technologies that rely on inputs other than lithium compounds, or a delay in the development and adoption of future high nickel battery technologies that utilize lithium hydroxide could significantly impact our prospects and future revenues. Many materials and technologies are being researched and developed with the goal of making batteries lighter, more efficient, faster charging, and less expensive, some of which could be less reliant on lithium hydroxide or other lithium compounds. Some of these technologies, such as commercialized battery technologies that use no, or significantly less, lithium compounds, could be successful and could adversely affect demand for lithium batteries in personal electronics, electric and hybrid vehicles, and other applications. We cannot predict which new technologies may ultimately prove to be commercially viable and on what time horizon. In addition, alternatives to industrial applications dependent on lithium compounds may become more economically attractive as global commodity prices shift. Any of these events could adversely affect demand for and market prices of lithium, thereby resulting in a material adverse effect on the economic feasibility of extracting any mineralization we discover and reducing or eliminating any reserves we identify.
 Our growth depends upon the continued growth in demand for electric vehicles with high performance lithium compounds.
 We plan to be one of a few producers of performance lithium compounds that are a critical input in current and next generation high energy density batteries used in electric vehicle applications. Our growth is dependent upon the continued adoption of electric vehicles by consumers. If the market for electric vehicles does not develop as we expect, or develops more slowly than we expect, our business, prospects, financial condition, and results of operations will be affected. The market for electric vehicles is relatively new, rapidly evolving, and could be affected by numerous external factors, such as:
 • government regulations and automakers' responses to these regulations
 • tax and economic incentives
 • rates of consumer adoption, which is driven in part by perceptions about electric vehicle features (including range per charge), quality, safety, performance, cost, and charging infrastructure
 • competition, including from other types of alternative fuel vehicles, plug-in hybrid electric vehicles, and high fuel-economy internal combustion engine vehicles
 • volatility in the cost of battery materials, oil, and gasoline
 • rates of customer adoption of higher performance lithium compounds and
 • rates of development and adoption of next generation high nickel battery technologies.

 Our cash and cash equivalents could be adversely affected if the financial institutions in which we hold our cash and cash equivalents fail.
 We maintain cash deposits in accounts that, at times may exceed the amount of insurance provided on such deposits by the FDIC. If one or more of the financial institutions in which we hold cash deposits fails, we could lose all or a portion of our uninsured cash balances. If access to our cash accounts in the future is impaired, whether temporarily or otherwise, we may be unable to pay our operational expenses such as payroll or make other payments. There can be no assurance that the FDIC will take actions to support deposits in excess of existing FDIC insured limits. If banks and financial institutions enter receivership or become insolvent in the future, including the financial institutions in which we, our equity method investments, or our customers hold cash, our and their ability to access existing cash, cash equivalents, and investments may be threatened and could have a material adverse effect on our business and financial condition. In addition, there is a risk that one or more of our current service providers, financial institutions, and other partners may be adversely affected by the foregoing risks, which could directly affect our ability to conduct our business plans on schedule and on budget.
 Risks Related to an Investment in Our Common Stock
 The market price and trading volume of our common stock may be volatile and may be affected by economic conditions beyond our control.
 The market price of our common stock may be highly volatile and subject to wide fluctuations. For instance, from January 1, 2024, through February 15, 2025, the closing price of our common stock on Nasdaq ranged from as high as $27.88 to as low as $6.58. In addition, the trading volume of our common stock may fluctuate and cause significant price variations to occur. If the market price of our common stock declines significantly, you may be unable to resell your shares of our common stock at or above the purchase price, if at all. We cannot assure you that the market price of our common stock will not fluctuate or significantly decline in the future.
 Some specific factors that could negatively affect the price of our common stock or result in fluctuations in the price and trading volume include:
 • actual or expected fluctuations in our prospects or operating results;
 • changes in the demand for, or market price of lithium, lithium hydroxide, or lithium-ion batteries;
 • additions to or departures of our key personnel;
 • changes or proposed changes in laws and regulations;
 • changes in trading volume of our common stock on Nasdaq or the ASX;
 • sales or perceived potential sales of our common stock by us, our directors, senior management, or our stockholders in the future;
 • announcement or expectation of additional financing efforts;
 • conditions in the financial markets or changes in general economic and political conditions and events, including repercussions from the wars in Ukraine and the Middle East;
 • market conditions or investor sentiment in the broader stock market, or in our industry in particular
 • introduction of new products and services by us or our competitors
 • issuance of new or changed securities analysts' reports or recommendations
 • litigation and governmental investigations and
 • changes in investor perception of our market position based on third-party information.
 When the market price of a stock is volatile, certain holders of that stock may institute securities class action litigation against the company that issued the stock. If any of our stockholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit or any future securities class litigation that may be brought against us.
 We incur significant costs as a result of being publicly traded in the U.S. and Australia.
 As a company whose common stock is publicly traded in both the U.S. and Australia, we incur significant legal, accounting, insurance, and other expenses related to compliance with applicable regulations. Our management and other personnel devote a substantial amount of time to these compliance initiatives, and we may need to continue to add additional personnel and build our internal compliance infrastructure.
 Our common stock is publicly traded on the ASX in the form of CDIs. As a result, we must comply with the ASX Listing Rules. We have policies and procedures that we believe are designed to provide reasonable assurance of our compliance with the ASX Listing Rules. If, however, we do not follow those procedures and policies, or they are not sufficient to prevent non-compliance, we could be subject to liability, fines, and lawsuits. These laws, regulations, and standards are subject to varying interpretations, and as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. We intend to invest resources to comply with evolving laws, regulations, and standards, and this investment may result in increased selling, general

 and administrative expenses, and a diversion of management's time and attention from growth and revenue-generating activities to compliance activities. If, notwithstanding our efforts to comply with new laws, regulations, and standards, we fail to comply, regulatory authorities may initiate legal proceedings against us, and our business may be harmed.
 Some provisions of Delaware law and our certificate of incorporation and bylaws may deter third parties from acquiring us or limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.
 Our certificate of incorporation and bylaws provide for, among other things:
 • a staggered board and restrictions on the ability of our stockholders to fill a vacancy on our Board
 • the authorization of undesignated preferred stock, the terms of which may be established and shares of which may be issued without stockholder approval
 • advance notice requirements for stockholder proposals
 • a requirement that, except as otherwise provided for or fixed with respect to actions required or permitted to be taken by holders of preferred stock, no action that is required or permitted to be taken by the stockholders may be affected by consent of stockholders in lieu of a meeting of stockholders;
 • permit the Board to establish the number of directors;
 • a provision that the Board is expressly authorized to adopt, amend, or repeal our amended and restated bylaws;
 • a provision that stockholders can remove directors only for cause and only upon the approval of not less than 66 2/3% of all outstanding shares of our voting stock;
 • a requirement that the approval of not less than 66 2/3% of all outstanding shares of our voting stock to adopt, amend, or repeal certain provisions of our bylaws and certificate of incorporation; and
 • limit the jurisdictions in which certain stockholder litigation may be brought.
 These anti-takeover defenses could discourage, delay, or prevent a transaction involving a change in control of our company. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors of their choosing and cause us to take other corporate actions than desired.
 Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the sole and exclusive forum for any complaint asserting any internal corporate claims (including claims in the right of the Company that are based upon a violation of a duty by a current or former director, officer, employee, or stockholder in such capacity, or as to which the Delaware General Corporation Law confers jurisdiction upon the Court of Chancery) or a cause of action arising under the Securities Act. This provision shall not apply to suits brought to enforce a duty or liability created by the Exchange Act. This choice of forum provision may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees. If a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business. For example, under the Securities Act, federal courts have concurrent jurisdiction over all suits brought to enforce any duty or liability created by the Securities Act, and investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder.
 We do not anticipate paying dividends in the foreseeable future.
 We have not declared any dividends during the years ended December 31, 2024, or 2023, and do not anticipate that we will do so in the foreseeable future. We currently intend to retain future earnings, if any, to finance the development of our business. Dividends, if any, on our outstanding shares of common stock will be declared by and subject to the discretion of the Board on the basis of our earnings, financial requirements, and other relevant factors. As a result, a return on your investment will only occur if our common stock price appreciates. We cannot assure you that our common stock will appreciate in value or even maintain the price at which you purchase shares of our common stock. You may not realize a return on your investment in our common stock, and you may even lose your entire investment in our common stock. Therefore, you should not rely on an investment in our common stock as a source for any future dividend income.
 If U.S. securities or industry analysts do not publish research reports about our business, or if they issue an adverse opinion about our business, the market price and trading volume of our common stock could decline.
 The trading market for our common stock will be influenced by the research and reports that U.S. securities or industry analysts publish about us and our business. Securities and industry analysts may discontinue research on us, to the extent such coverage currently exists, or in other cases, may never publish research on us. If no, or too few, U.S. securities or industry analysts commence coverage of our Company, the trading price for our common stock would likely be negatively affected. In the event securities or industry analysts initiate coverage, if one or more of the analysts who cover us downgrade our common stock or publish inaccurate or unfavorable research about our business, the market price of our common stock would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our common stock could decrease, which might cause our

 price and trading volume to decline. In addition, research and reports that Australian securities or industry analysts publish about us, our business, or our common stock may impact the market price of our common stock.
 Unstable market and economic conditions may have serious adverse consequences on our business and financial condition.
 Global credit and financial markets have experienced extreme disruptions at various points over the last few decades, characterized by diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, and uncertainty about economic stability. If another such disruption in credit and financial markets and deterioration of confidence in economic conditions occurs, our business may be adversely affected. If the equity and credit markets were to deteriorate significantly in the future, it may make any necessary debt or equity financing more difficult to complete, more costly, and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance, and share price and could require us to delay or abandon development or commercialization plans. In addition, there is a risk that one or more of our service providers, manufacturers, or other partners would not survive or be able to meet their commitments to us under such circumstances, which could directly affect our ability to attain our operating goals on schedule and on budget.
 Sales of our common stock, or the perception that such sales may occur, could depress the price of our common stock.
 Sales of a substantial number of shares of our common stock in the public market, or the perception that such sales may occur, could depress the market price of our common stock. We have filed a registration statement registering under the Securities Act the shares of our common stock reserved for issuance under our Stock Incentive Plan, including shares issuable upon exercise of outstanding options. These shares can be freely sold in the public market upon issuance, subject to volume limitations applicable to affiliates. Further, as opportunities present themselves, we may enter into financing or similar arrangements in the future, including the issuance of debt or equity securities. If we issue common stock or securities convertible into our common stock, our common stockholders would experience additional dilution, and as a result, the price of our common stock may decline.

 Item 1C. CYBERSECURITY.
 Cybersecurity Risk Management and Strategy
 We recognize the importance of developing, implementing, and maintaining robust cybersecurity measures to safeguard our information systems and protect the confidentiality, integrity, and availability of our data. As a result, we have integrated cybersecurity risk management into our broader risk management framework to promote a holistic approach toward assessing, identifying, and managing material risks associated with cybersecurity threats. This integration ensures that cybersecurity considerations are an integral part of the decision-making processes at every level of our organization.
 Recognizing the complexity and evolving nature of cybersecurity threats, we have partnered with third-party cybersecurity agencies to leverage specialized knowledge and insights, ensuring our cybersecurity strategies and processes remain at the forefront of industry best practices. Our cybersecurity partners work to continuously scan and monitor our networks for threats and vulnerabilities and provide access to a 24/7 incident response team. Further, through our partnerships, we conduct annual security risk assessments, which are designed in alignment with the National Institute of Standards and Technology Cybersecurity Framework and perform annual penetration tests and breach and attack simulations to validate security controls. These partnerships are actively managed by members of our management team, together with our information technology department, to ensure effective implementation.
 Additionally, to best position Piedmont Lithium to avoid cybersecurity incidents, we, among other things, conduct employee trainings and, where appropriate, utilize a coordinated procurement process to bring consistency, compliance, and interoperability to the hardware, software, and services we obtain from vendors and other business partners. This coordinated procurement process includes, in addition to other safeguards, review by our information technology and legal departments to address any security concerns before any vendor or business partner is granted access to our information systems.
 As of the date of this Annual Report, we have not identified risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have or are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. While we continually work to safeguard the information systems we use, and the proprietary, confidential and personal information residing therein, and mitigate potential risks, there can be no assurance that such actions will be

 sufficient to prevent cybersecurity incidents or mitigate all potential risks to such systems, networks and data or those of our third-party providers. For additional information, refer to Part I, Item 1A, "Risk Factors—Our business is subject to cybersecurity risks."
 Governance
 Cybersecurity is an important part of our risk management processes and an area of focus for our Board and management team. Our Audit Committee is responsible for the Board-level oversight of risks from cybersecurity threats. Members of our Audit Committee receive updates from our management team regarding Company practices, programs, and other developments related to cybersecurity throughout the year, including quarterly updates from our Chief Legal Officer on cyber threats and our cybersecurity risk management and strategy program. Our Audit Committee is comprised of Board members with diverse expertise, including risk management and strategy, equipping each member to oversee cybersecurity risks effectively.
 We maintain a Cybersecurity Incident Response Team composed of professionals across various functions, including information technology, legal, finance, accounting, and risk. This team is trained in managing cybersecurity incidents and is comprised of individuals with experience in various roles involving information technology, including, security, auditing, compliance, systems, and programming.

 Item 2. PROPERTIES.
 We lease our corporate headquarters in Belmont, North Carolina and lease additional office space in Cherryville, North Carolina. We own and lease properties in Gaston and Cleveland Counties in North Carolina, primarily for the principal use of current development activities for Carolina Lithium. We expect to further our principal use to include mining, development and production of lithium hydroxide and other lithium products and byproducts.
 In October 2023, we purchased a 132-acre disposal facility adjacent to the previously proposed Tennessee Lithium plant site for the placement of inert tailings produced as part of the innovative alkaline pressure leach process. We currently hold a Solid Waste Disposal Permit for this disposal facility.

 Mineral Properties
 The below table discloses, as of December 31, 2024, our relevant mineral properties categorized as wholly-owned and owned through direct investment. We classify our mineral properties into three categories: "Production Properties," "Development Properties," and "Exploration Properties." Production Properties are properties with material extraction of mineral reserves. Development Properties are properties that have mineral reserves disclosed but no material extraction. Exploration Properties are properties that have no mineral reserves disclosed. We currently categorize both Carolina Lithium and NAL as material individual properties under S-K 1300 and provide additional details accordingly under "Material Individual Properties."

 As of December 31, 2024, we owned a 25% equity interest in Sayona Quebec. Sayona Quebec owns the now-producing NAL, the Authier Lithium project, and the Tansim Lithium project. Additionally, in November of 2022, Sayona Quebec, through NAL, entered into an acquisition and earn-in agreement with Jourdan Resources Inc. to purchase 20 claims of Vall e and to earn up to a 51% equity interest in the remaining 28 claims. As part of the agreement, NAL became a 9.99% equity holder of Jourdan Resources Inc.
 Through our strategic partnership, Sayona Quebec is prioritizing the manufacturing of lithium products in Quebec and capitalizing on Quebec's competitive advantages, which include access to skilled labor, strong infrastructure, governmental mining support and zero-carbon, low-cost hydropower. As of December 31, 2024, our investments in Sayona Quebec totaled $ 70.2 million.
 Revenue and expenses of Sayona Quebec are not consolidated into our financial statements; rather, our proportionate share of the income or loss is reported as "(Loss) income from equity method investments" in our consolidated statements of operations.
 Offtake Agreement
 In January 2021, we entered into a long-term offtake agreement with Sayona Quebec. Under the terms of the offtake supply agreement, Sayona Quebec will supply Piedmont Lithium the greater of 113,000 dmt per year or 50% of Sayona Quebec's spodumene concentrate production from the combination of NAL and the Authier project. Under the agreement, spodumene concentrate is priced on a market price basis with a floor price of $500 per dmt and a ceiling price of $900 per dmt for SC6.

 Vinland Lithium
 As of December 31, 2024, we owned an equity interest of approximately 19.9% in Vinland Lithium, which is a Canadian-based entity which owns Killick Lithium, the owner of a large exploration property prospective for lithium located in southern Newfoundland, Canada. As of December 31, 2024, we have invested $ 1.5 million in Vinland Lithium.
 Offtake and Project Agreement
 In October 2023, we entered into an earn-in agreement with Vinland Lithium to acquire up to a 62.5% equity interest in Killick Lithium through staged-investments. As part of our investment, we entered into a marketing agreement with Killick Lithium for 100%

 marketing rights and right of first refusal to purchase 100% of all lithium products produced by Killick Lithium on a life-of-mine basis at competitive commercial rates.

 Equity Method Investment Properties
 The information below specific to each property is derived from information publicly disclosed by each such investee company. Additionally, the disclosed mineral reserves estimates and mineral resources estimates of NAL and Authier are presented according to the following principals.

 Mineral Reserves
 A "mineral reserve" is an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the QP, can be the basis of an economically viable project. Specifically, mineral reserve is the economically mineable part of a measured or indicated mineral resource. The term "economically viable," as used in the definition of reserve, means that the QP has analytically determined that extraction of the mineral reserve is economically viable under reasonable investment and market assumptions.
 The term "proven reserves" means the economically mineable part of a measured mineral resource and can only result from conversion of a measured mineral resource. The term "probable reserves" means mineral reserves for which quantity and grade are computed from information similar to that used for proven reserves, but the sites for sampling are farther apart or are otherwise less closely spaced. The degree of assurance, although lower than that for proven reserves, is high enough to assume continuity between points of observation.
 Proven and probable mineral reserves are based on extensive drilling, sampling, mine modeling, and metallurgical testing from which we determined economic feasibility. The reference point for mineral reserves is the undiluted ore, excluding dilution material, delivered to our spodumene concentrator. The price sensitivity of mineral reserves depends upon several factors including grade, metallurgical recovery, operating cost, and waste-to-ore ratio. Each respective mineral reserves table in this Item 2 lists the estimated metallurgical recovery rate of spodumene concentrate. The cut-off grade, or lowest grade of mineralization considered economic to process, depends upon prevailing economic conditions, estimated mineability of our deposit, and amenability of the mineral reserve to spodumene concentration.
 The proven and probable reserve figures presented herein are estimates based on information available at the time of calculation. No assurance can be given that the estimated levels of metallurgical recovery of lithium minerals will be realized. Metric tons of ore containing lithium minerals included in the proven and probable reserves are those contained prior to losses during metallurgical treatment. Reserve estimates may require revision based on actual production. Market fluctuations in the price of spodumene concentrate, lithium hydroxide, or lithium carbonate, as well as increased production costs or reduced metallurgical recovery rates, could render certain proven and probable reserves containing higher cost reserves uneconomic to exploit and might result in a reduction of mineral reserves.

 Mineral Resources
 The mineral resource figures presented herein are estimates based on information available at the time of calculation and are exclusive of reserves. A "mineral resource" is a concentration or occurrence of solid 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 eventual economic extraction. The location, quantity, grade or quality, continuity and other geological characteristics of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling. The reference point for mineral resources is in situ. Mineral resources are subdivided in order of increasing geological confidence into inferred, indicated and measured categories. Metric tons of mineral resources containing spodumene, quartz, feldspar and mica, included in the measured, indicated, and inferred resources, are those contained prior to losses during metallurgical treatment. The terms "measured resource," "indicated resource," and "inferred resource" mean the part of a mineral resource for which quantity and grade or quality are estimated on the basis of geological evidence and sampling that is considered to be comprehensive, adequate, or limited, respectively.
 Market fluctuations in the price of lithium hydroxide as well as increased production costs or reduced metallurgical recovery rates, could change future estimates of resources. We have reported mineral resources, prepared in accordance with S-K 1300, as part of our exploration and evaluation activities.

 Quebec Properties
 Sayona Quebec's assets are comprised of four wholly-owned projects as follows: NAL, which restarted production in 2023, the Authier project, which is in the development stage, and Tansim and Vall e, which are both in the exploration stage. Additionally, Sayona Quebec entered into a joint-venture agreement with Jourdan Resources Inc. to jointly develop additional Vall e claims, which are also in the exploration stage.

 Authier
 Authier is located approximately 28 miles northwest of the city of Val-d'Or. Val-d'Or is located approximately 290 miles northwest of the city of Montreal. Authier is easily accessible by a rural road network that is connected to a national highway a few miles east of the project site. The project area comprises 24 mineral claims totaling 2,184 acres and directionally extends 2.6 miles east-west and 2.1 miles north-south. The mineral claims are located over Crown Lands, which is land owned by the Province of Quebec.

 Figure 2
 The spodumene-bearing pegmatite is principally defined by one single continuous intrusion, or dyke, that contains local rafts, or xenoliths, of the amphibolitic host rock, which are approximately 10 feet thick and up to 656 feet in length at shallow levels within the western zone. The main pegmatite outcrops in a small, 164 feet by 65 feet, area at the central-eastern sector that orients east-west and is mostly covered by up to 32 feet of overburden. Based on the information gathered from the drilling, the pegmatite intrusion is more than 3,608 feet in length and can be up to 196 feet thick. The intrusion is generally oriented east-west, dips to the north at angles ranging between 35 and 50 and reaches depths of up to 885 feet below surface in drilling to date.
 A second spodumene-bearing pegmatite, not visible from the surface, was intersected by diamond hole AL-16-10 at shallow levels, between 49 feet and 72 feet downhole depth, approximately 1,312 feet north of the main pegmatite. Follow-up drilling in early 2017 and 2018 outlined this new body, the Authier North pegmatite, which has a strike extension of 1,640 feet east-west, 22 feet average width, gently dipping 15 degrees to the north. The Authier North pegmatite appears at shallow levels, 49 feet to 82 feet vertical depth, and is open in all directions.
 Authier has been subject to more than 19 miles of exploration drilling. Between 2010 and 2012, Glen Eagle, the previous tenement holder, completed approximately 6 miles of diamond drilling in 69 diamond drill holes of which 5 miles were drilled on the Authier deposit; 1,998 feet (five diamond drill holes) were drilled on the northwest and 1,384 feet on the south-southwest of the property. Sayona Quebec completed four phases of drilling totaling more than 8.7 miles in 94 diamond drill holes. All the holes completed by Sayona Quebec have used standard diamond drill hole diameter size, using a standard tube and bit.
 Sayona Quebec continues to closely engage with all stakeholders concerning Authier's development by, among other things, holding information sessions and consultations with local municipalities, landowners, First Nations communities, nongovernmental organizations and other stakeholders.

 Environmental baseline studies including literature review, field works and laboratory analysis have been undertaken on the Authier project in 2012, and again from 2017 to 2022 by Sayona Quebec and the previous project owner. Sayona Quebec has progressed environmental studies on the project in accordance with Quebec's regulatory requirements. In 2023, the Government of Quebec agreed with Sayona Quebec's request to voluntarily submit the Authier project to the Quebec BAPE process. In line with its commitment to transparency and collaboration, Sayona's request will allow citizens to get involved in the project's development. The BAPE's mission is to inform government decision-making by issuing findings and opinions that account for the public's concerns and are based on the principles of the Sustainable Development Act.
 A technical report summary with respect to our estimated resources and reserves at Authier is filed as an exhibit to this Annual Report as Exhibit 96.2. The "Summary Resources Table and Summary Reserves Table" located above in this Item 2 reflect only those resources and reserves attributable to our ownership or economic interest as of December 31, 2024, and such reported resources and reserves have been prepared in accordance with S-K 1300.
 The following table details measured, indicated and inferred resources which have been prepared in accordance with S-K 1300 and are solely attributable to our ownership or economic interest as of December 31, 2024.

 (1) Mineral resources are 100% attributable to the property. Values shown in the table are based on Piedmont Lithium's economic interest in the mineral resource. Piedmont Lithium had a 25% economic interest in the Authier project as of December 31, 2024.
 Mineral Reserves
 Probable mineral reserves have been estimated and based on the consideration of pertinent modifying factors, inclusive of geological, environmental, regulatory and legal factors, in converting a portion of the mineral resources to mineral reserves. A cutoff grade of 0.55% Li2O based on metallurgical recovery limitations was used in creation of the block model. An open pit mining method was selected due to the depth of the ore body. No other mining method was evaluated as part of the mineral reserves estimation. Mine design parameters include an overburden berm width of less than 1 foot, overburden bench face angle of 14 degrees, and a setback at the overburden fresh rock contact of 33 feet. Mine design parameters additionally include 20 foot bench heights, berm widths of 27 feet, inter ramp angles ranging from 156 to 189 feet and bench face angles ranging from 65 to 80 degrees. The single lane ramp width is 56 feet with the dual lane ramp measuring 76 feet with a maximum ramp grade of 10%. Mining ore losses have been estimated at 2.3%, and mine dilution of approximately 9%. To account for additional operational errors and re-handling an additional mine ore loss factor of 2.0% was applied. Process recovery for spodumene concentrate is estimated to be 73.6%.

 The following table details proven and probable reserves reflecting only those reserves attributable to our ownership or economic interest as of December 31, 2024, and have been prepared in accordance with S-K 1300.

 (1) Reserves are expressed as tonnages and grades reported as run-of-mine feed at the NAL crusher and account for mining dilution, geological losses, and operational mining loss factors. Pricing to support mineral reserve economics is based upon the sale of run-of-mine ore from the Authier project to North American Lithium at a transfer price of CAD$120 per dmt. The selected optimized pit shell is based on a revenue factor of 0.86 applied to a base case selling price for spodumene concentrate of 850 per dmt of SC6. Mineral reserves estimated are exclusive of the mineral resources.

 Tansim
 Tansim is situated 51 miles south-west of Authier. Tansim comprises 355 mineral claims spanning 50,749 acres and is prospective for lithium, tantalum, and beryllium.
 Mineralization is hosted within spodumene-bearing pegmatite intrusions striking east-west, dipping to the north, and hosted by metasedimentary – metavolcanic rocks of the Pontiac sub-province. The main prospects are Viau-Dallaire, Viau and Vezina. The potential quantity and grade of the exploration target is uncertain as there has been insufficient exploration to estimate a mineral resource, and it is uncertain if further exploration will result in the estimation of a mineral resource.

 Vall e
 Vall e is located in Abitibi, Quebec, near the township of La Corne and comprises 48 claims covering approximately 4,934 acres, closely neighboring the NAL mine tenure with 20 claims located within 550 yards of the NAL mine boundary. See Figure 3 below.

 Figure 3: Vall e

 In November 2022, NAL acquired those 20 claims outright, which span approximately 1,866 acres. Such claims allow for potential future infrastructure expansion at the NAL mine and its processing facility. In December 2023, NAL earned its initial 25% stake in the remaining 28 claims and has the right to earn up to a 51% stake in total.
 As of December 31, 2024, a total of 66 diamond drill holes measuring a total depth of approximately 10 miles has been completed at Vall e.
 The project is situated within the heart of the southern portion of the Abitibi Greenstone Belt, some 62 miles northeast of the mining towns of Rouyn Noranda, 28 miles north of Val d'Or, 31 miles northeast of Malartic (home to the Canadian Malartic Mine), 19 miles southeast of Amos and contiguous and in proximity to RB Energy's Quebec Lithium Property and adjacent to the NAL mine.
 The mineralized spodumene pegmatite dykes that NAL has mined continue directly onto the claims of Vall e.

 Newfoundland

 Killick Lithium is an exploration stage project currently operated by Sokoman Minerals and Benton Resources that consists of 3,146 claims totaling approximately 234,748 acres, accessible by the Burgeo Highway in southwestern Newfoundland. See Figure 4 below.

 Figure 4: Killick Lithium location, showing proximity to highway and grid power.
 According to their data, Benton Resources and Sokoman Minerals completed 61 exploratory drill holes, 50 of which intersected spodumene-bearing pegmatites. Mineralization in surface trenching and drilling has been identified over a strike length of 1.5 miles. These early drilling results include multiple intercepts over 1.0% Li2O and demonstrate the potential for additional discoveries within the property. Their exploration work in 2023 identified numerous soil and geophysical anomalies, highlighting high-priority drill targets. The property features excellent infrastructure with close proximity to paved roadways, an electrical substation, and an ice-free, deepwater port.

 Ghana

 Ewoyaa Lithium Project
 We have a strategic partnership with Atlantic Lithium that includes Atlantic Lithium Ghana's flagship Ewoyaa project. Under our partnership, we entered into a project agreement to acquire a 50% equity interest in Atlantic Lithium Ghana in two phases, with each phase requiring us to make future staged investments in Ewoyaa over a period of time in order to earn our additional equity interest. We completed Phase 1 of our investment in mid-2023, which allows us to acquire a 22.5% equity interest in Atlantic Lithium Ghana, by funding Ewoyaa's exploration activities and DFS costs and notifying Atlantic Lithium of our intention to proceed with additional funding contemplated under Phase 2, which mainly consists of construction and development activities for Ewoyaa. Our future equity interest ownership under Phase 1 remains subject to government approvals. Phase 2 allows us to acquire an additional 27.5% equity interest in Atlantic Lithium Ghana upon completion of funding $70 million for capital costs associated with the development of Ewoyaa. Upon issuance of our equity interest associated with Phase 1 and completion and issuance of our equity interested associated with Phase 2, we expect to have a total equity interest of 50% in Atlantic Lithium Ghana. Atlantic Lithium Ghana, in turn, will hold an 81% interest in the Ewoyaa project net of the interests that will be held by the Ghanaian government and MIIF, which will result in an effective ownership interest of 40.5% in Ewoyaa, by Piedmont Lithium. As of December 31, 2024, we did no t own an equity interest in Atlantic Lithium Ghana.
 Ewoyaa is a development stage project for the mining, development and production of spodumene concentrate located on the south coast of Ghana and covers an area of approximately 348 square miles.
 Ewoyaa includes the Ewoyaa, Abonko, and Kaampakrom deposits, and is located in Ghana, West Africa, approximately 60 miles southwest of the capital of Accra. The project area is immediately north of Saltpond, in the Central Region, and falls within the Mfantseman Municipality where Saltpond is the district capital. See Figure 5 below.
 Access to the site from Accra is along the asphalt N1 Accra-Cape Coast-Takoradi Highway which runs along the southern coastal boundary of the project. Several laterite roads extend northwards from the highway and link communities in the project area. The deep-sea Port of Takoradi is within 70 miles west of the Ewoyaa site and accessible via the same highway. See Figure 5 below.

 Figure 5: Ewoyaa location and tenure, showing proximity to Takoradi Port, highway and grid power.
 The topography of the project varies with steep hills surrounding low-lying valleys throughout the proposed mining area. The terrain of the project area rises sharply from a narrow coastal plane to an undulating peneplane where elevation ranges from 66 feet to 394 feet above mean sea level.

 Ghana is a republic within the Commonwealth. Ghana gained independence from colonial Britain in 1957, being the first sub-Saharan African country in colonial Africa to do so. Despite some turbulent history in the first decades following independence, Ghana has emerged since the 1990s as a stable, multi-party democracy.

 Figure 6: High voltage power transmission lines, bitumen highway and deep-sea Takoradi port close to project site.
 Ewoyaa covers two contiguous exploration licenses, the Mankessim (RL 3/55) and Mankessim South (RL PL3/109) licenses. The Mankessim is a joint venture, with the license in the name of the joint venture party, Barari DV Ghana; document number 0853652-18. The Mineral Prospecting License was renewed on July 27, 2021, for a further three-year period valid through July 26, 2024. Mankessim South is a wholly-owned subsidiary of Green Metals Resources. A Mineral Prospecting License was renewed on February 19, 2020, for a further three-year period through February 18, 2023. The tenement is in good standing with no known impediments.
 In October 2023, Atlantic Lithium announced Ghana's Ministry of Lands and Natural Resources granted a mining lease for Ewoyaa. The mining lease provides exclusive rights to carry out lithium mining and commercial production activities for an initial 15-year period and is renewable in accordance with Ghanaian legislation. The issuance of the mining lease is subject to ratification by the Ghanaian parliament, approval of the Environmental Protection Agency of Ghana, and other statutory requirements. The mining lease provides the Government of Ghana a 13% free-carried interest and a 10% royalty in Ewoyaa.

 Material Individual Properties
 We categorize Carolina Lithium and NAL as material individual properties under S-K 1300.

 Material Individual Property - Carolina Lithium

 Carolina Lithium is a development stage project for the mining, development and production of lithium products. The property is located in a rural area of Gaston County, North Carolina, approximately 25 miles northwest of the City of Charlotte. The property is centered at approximately 35 23'20"N 81 17'20"W. The property currently has no known encumbrances. In addition to the information summarized below, you can learn more about Carolina Lithium by reading the technical report summary dated April 20, 2023, attached as Exhibit 96.1 and incorporated by reference to Exhibit 96.3 to our Annual Report on 10-K/A dated April 25, 2023.
 Spodumene Concentrate Operation
 The technical report summary for Carolina Lithium is based on a mine life of 11 years of mineral reserves, with an estimated average annual production of 242,000 metric tons of spodumene concentrate at steady-state operation.
 We believe there is significant opportunity to increase the mineral reserve life of Carolina Lithium beyond 11 years by conversion of existing mineral resources to mineral reserves or by discovery of additional resources within the Carolina Tin-Spodumene Belt within a reasonable trucking or conveying distance to the proposed spodumene concentrator.

 Lithium Hydroxide Conversion Operation
 The technical report summary for Carolina Lithium assumes a lithium hydroxide conversion plant, also referred to as a chemical plant, that will be supported with spodumene concentrate produced from our mineral reserves and that the lithium hydroxide chemical plant has an estimated production rate of 30,000 metric tons of lithium hydroxide per year.
 Our business plan is, upon depletion of our mineral reserves, to continue lithium hydroxide production at Carolina Lithium using spodumene concentrate sourced from offtake agreements, which will allow us to secure spodumene concentrate from alternate sources or from our own mineral reserves if our estimation of mineral reserves was increased in the future.
 Operating and Capital Costs
 According to the technical report summary results, our integrated Carolina Lithium project is projected to have an average cash operating cost of approximately $4,844 per metric ton of lithium hydroxide at steady state during the first 10 years of operations, including royalties and exclusive of any byproduct credits, thereby potentially positioning Piedmont Lithium as one of the industry's lowest-cost producers. The technical report summary estimates, in accordance with the Association the Advancement of Cost Engineering class 3 level of detail, total capital costs of approximately $1 billion for the construction of the fully integrated Carolina Lithium project, inclusive of potential recovery of byproduct mineral resources.
 Ownership and Location
 We hold a 100% interest in Carolina Lithium which is located approximately 25 miles northwest of Charlotte, North Carolina in the U.S.
 History
 Carolina Lithium lies within the Carolina Tin-Spodumene Belt. Mining in the belt began in the 1950s with the Kings Mountain Mine, currently owned by Albemarle Corporation, and the Hallman-Beam Mine near Bessemer City, North Carolina, which is currently owned by Martin Marietta Corporation. Both former mines are located within approximately 12 miles of Carolina Lithium to the south, near Bessemer City, North Carolina, and Kings Mountain, North Carolina, respectively. Portions of the project area were explored and excavated to shallow depths in the 1950s as the Murphy-Houser Mine, owned by the Lithium Corporation of America. In 2009, Vancouver-based North Arrow Minerals Inc. commenced exploration at the property. In 2016, we began optioning surface and mineral rights at the property and subsequently commenced a renewed exploration effort at the site.
 Present Condition, Work Completed, and Exploration Plans
 General access to Carolina Lithium is via a network of primary and secondary roads. Interstate highway I 85 lies 6 miles to the south of the project area and provides easy access to Charlotte Douglas International Airport, which is approximately 19 miles to the east. A rail line borders the property to the northwest. Transport links provide access to Charlotte, which is the largest city based on size and population in North Carolina, within approximately 25 miles from Carolina Lithium. Extensive exploration supports our resource estimate and is comprised of surface mapping and extensive subsurface drilling. Between 2017 and 2021, we completed five phases of exploratory drilling which included a total of 542 core holes amounting to approximately 50 miles to define the Core property deposit. The exploration of Carolina Lithium has been performed by professional geologists in adherence to established operating procedures that have been verified by the qualified person. Through the date of this report, exploration has been concentrated on the Core, Central, and Huffstetler deposit areas detailed in Figure 8 below.

 Properties

 Figure 7
 As of December 31, 2024, Carolina Lithium, was comprised of real property and associated mineral rights totaling approximately 3,482 acres, of which approximately:
 •219 parcels consisting of 2,907 acres are owned with a book value of $88.3 million;
 •1 parcel consisting of 113 acres is subject to long-term leases with a book value of $0.2 million; and
 •36 parcels consisting of 462 acres are subject to exclusive option agreements with a book value of $1.3 million. These exclusive option agreements, upon exercise, allow us to purchase or, in some cases, enter into long-term lease agreements for the real property and associated mineral rights. Our option agreements provide for annual option payments, bonus payments during periods when we conduct drilling, and royalty payments during periods when we conduct mining. Our option agreements generally provide us with an option to purchase the optioned property at a specified premium over fair market value. Upon exercise of our purchase option, our obligation to make annual option payments and bonus payments terminates.

 We generally control all the surface and mineral rights for Carolina Lithium under applicable agreements. We also own real property totaling 5 acres in Bessemer City, North Carolina, where we lease a warehouse for core samples from Carolina Lithium, and 61 acres in Kings Mountain, North Carolina, where we hold a synthetic minor air permit, and which was the subject of prior technical studies for a planned lithium hydroxide conversion facility.

 Figure 8

 Mineral Reserves
 As of December 31, 2024, we have reported no proven mineral reserves and 18.3 million metric tons of probable mineral reserves at a grade of 1.10% Li2O. We issued our first mineral resource estimate on October 21, 2021, and have not finalized any new estimates. The proven and probable reserve figures presented herein are estimates based on information available at the time of calculation.
 A technical report summary with respect to our estimated mineral reserves was filed as an exhibit to our Transition Report on Form 10-KT for the six-month period ending December 31, 2021. This technical report summary was amended to include certain information as required by S-K 1300. The amended technical report study dated April 20, 2023, attached as Exhibit 96.1 for the period ending December 31, 2022. We publish reserves annually and will recalculate reserves if any new significant changes are expected, taking into account metal prices, changes, if any, to future production and capital costs, divestments and depletion as well as any acquisitions and additions during the period.
 Probable mineral reserves have been estimated and based on the consideration of pertinent modifying factors, inclusive of geological, environmental, regulatory and legal factors, in converting a portion of the mineral resources to mineral reserves. All converted mineral resources were classified as probable mineral reserves. There were no measured mineral resources defined that could be converted into proven mineral reserves, and no inferred mineral resources were included in the estimation of mineral reserves. A cutoff grade of 0.4% Li2O was used in creation of the block model. An open pit mining method was selected due to the ore body outcropping in several places along the surface. No other mining method was evaluated as part of the mineral reserves estimation. Mine design parameters include overburden batter angle in unconsolidated material of 27 degrees, face batter angle of 75 degrees, inter-ramp slope of 57 degrees, overall slope of 51 degrees, berm width of 31 feet, berm height working 39 feet, berm height final wall of 78 feet, ramp width

 of 98 feet, ramp grade of 10%, mine dilution of 10%, process recovery for spodumene concentrate of 77%, and minimum mining width of 164 feet.
 Operating costs were established using budget pricing from mining contractors based on a request for proposal issued by our third-party consultant, Marshall Miller and Associates, combined with first principles estimates for utilities including electrical service from Duke Energy. Royalties of $1.00 per run-of-mine metric ton are based on the average land option agreement.
 Mineral reserves include tonnage estimates for Li2O and LCE, whereby one metric ton of Li2O is equivalent to 2.473 metric tons of LCE.
 The following table details proven and probable reserves reflecting only those reserves attributable to our ownership or economic interest as of December 31, 2024, and have been prepared in accordance with S-K 1300.

 (1) Reserves are expressed as tonnages effectively delivered to a run-of-mine pad, prior to the application of losses and recovery factors (i.e., metallurgical recovery as expressed above) incurred during concentration and conversion. Pricing to support mineral reserve economics is based upon the sale of lithium hydroxide, after the processing of run-of-mine reserves in our planned spodumene concentrator and lithium hydroxide conversion facilities. Mineral reserves estimated exclusive of the mineral resources.
 (2) Based on long-term pricing of $1,893 per metric ton of spodumene concentrate.
 (3) Metallurgical recovery of 77% for lithium ore is associated with the production of a 6% spodumene concentrate.

 Mineral Resources
 As of December 31, 2024, we have reported 25.89 million metric tons of mineral resources, exclusive of mineral reserves, at a grade of 1.06% Li2O.
 The resource figures presented herein do not include that part of our resources that have been converted to proven and probable reserves as shown above, as they are reported exclusive of reserves, and have been estimated based on information available at the time of calculation. Key assumptions and parameters relating to the mineral reserves and resources are discussed in Sections 1.9 and 1.10 of the Carolina Lithium project amended technical report summary attached as Exhibit 96.1.
 Resource models are constrained by a conceptual pit shell derived from a Whittle optimization using estimated block value and mining parameters appropriate for determining reasonable prospects of economic extraction. These parameters include maximum pit slope of 51 and strip ratio of 12, mining cost of US$2.50 per ton, spodumene concentration cost of US$25 per ton, a commodity value of US$1,893 per ton of SC6 and with appropriate recovery and dilution factors.

 Comparison of Resources and Reserves as of December 31, 2024 and 2023
 No mineral resource estimates and no mining operations at Carolina Lithium were conducted during the current reporting period. As a result, we are not providing an analysis of changes in mineral resources and mineral reserves for those periods.

 Material Individual Property - NAL

 NAL is comprised of 19 contiguous claims covering 1,438 acres and one mining lease covering approximately 1,729 acres. NAL is situated in La Corne township in Quebec's Abitibi region. The project is located approximately 20 miles from Authier near Val-d'Or, a major mining city in Quebec.
 NAL is a brownfield open pit mining operation with a concentrator and a carbonate plant and was acquired by Sayona Quebec in August 2021. Prior to acquisition by Sayona Quebec, more than CAD 400 million was invested in NAL. NAL receives most of its power from hydroelectricity and is well serviced by provincial highways and an all-weather secondary road. Production restarted in March of 2023 and the inaugural shipment of spodumene concentrate occurred in August 2023.
 The 2023 and 2024 drill campaigns at NAL identified new, high-grade mineralized zones along the northwest margin of the NAL deposit, beyond the current NAL pit operations and the planned pit shell model. Additionally, mineralization from inside the pit shell model shows continuity and consistency in grade and thickness, providing the potential for mineral resource conversion within the pit shell model as well as definition below the existing pit. As of December 31, 2024, a total of 201 diamond drill holes measuring a total depth of approximately 34 miles were completed at NAL.

 Mineral Reserves
 As of December 31, 2024, we have reported 0.05 million metric tons of proven mineral reserves at a grade of 1.40% Li2O and 4.90 million metric tons of probable mineral reserves at a grade of 1.08% Li2O.
 A technical report summary with respect to our estimated mineral reserves at NAL is filed as Exhibit 96.3 to this Annual Report on Form 10-K. We publish reserves annually and will recalculate reserves if any new significant changes are expected, taking into account metal prices, changes, if any, to future production and capital costs, divestments, and depletion as well as any acquisitions and additions during the period.
 Proven and probable mineral reserves have been estimated and based on the consideration of pertinent modifying factors, inclusive of geological, environmental, regulatory and legal factors, in converting a portion of the mineral resources to mineral reserves. A diluted cutoff grade of 0.60% Li2O based inclusive of 16% life-of-mine dilution was used to establish the run-of-mine feed. An open pit

 mining method was selected due to the depth of the ore body. While underground mining alternatives have been evaluated in prior studies no measured or indicated mineral resources exist at a depth where underground mining is considered the most viable alternative, therefore the mineral reserves have been estimated on the basis of open pit mining only. Mine design parameters include a weathered zone berm width of 30 feet with a bench face angle of 26.6 degrees. Mine design parameters in fresh rock include a maximum 66-foot bench height, bench widths of 33 to 53 feet, inter ramp angles between 45.7 and 52.6 degrees and a bench face angle of 60 to 80 degrees. The overall single lane ramp width is 67 feet with the dual lane ramp measuring 92 feet with a maximum ramp grade of 10% for permanent roads and 12% for temporary roads. Mining ore losses have been estimated at 3%, and mine dilution of approximately 16%.
 Mineral reserves include tonnage estimates for Li2O, and LCE, whereby one metric ton of Li2O is equivalent to 2.473 metric tons of LCE.
 The following table details proven and probable reserves reflecting only those reserves attributable to our ownership or economic interest as of December 31, 2024, and have been prepared in accordance with S-K 1300.

 (1) Reserves are expressed as tonnages effectively delivered to a run-of-mine pad, prior to the application of losses and recovery factors (i.e., metallurgical recovery as expressed above) incurred during concentration. A dilution factor of 16% is included in the ore tons delivered to the run-of-mine pad.
 (2) Pricing to support mineral reserve economics is based upon the sale of spodumene concentrate at an average grade of 5.40% Li2O until 2027 after which the concentration grade is increased to 5.82%. Mineral reserves estimated exclusive of the mineral resources.
 (3) The overall metallurgical recovery from spodumene concentrate.

 Mineral Resources
 As of December 31, 2024, we have reported 10.08 million metric tons of mineral resources at NAL, exclusive of mineral reserves, at a grade of 1.21% Li2O.
 The resource figures presented herein do not include that part of our resources that have been converted to proven and probable reserves as shown above, as they are reported exclusive of reserves, and have been estimated based on information available at the time of calculation. Key assumptions and parameters relating to the mineral reserves and resources are discussed in Sections 1.7 and 1.8 of the North American Lithium project technical report summary filed as Exhibit 96.3 in this Form 10-K.
 Resource models are constrained by a conceptual pit shell derived from a Whittle optimization using estimated block value and mining parameters appropriate for determining reasonable prospects of economic extraction. These parameters include: a constraining pit shell slope between 46 to 53 degrees, a concentrate selling price of $1,273 per metric ton for 5.4% Li2O product, mining costs of $5.12 per ton mined, recovery of 73.6%, spodumene concentration cost of $23.44 per ton, general and administrative expense of $6.00 per ton processed, transportation costs of $118.39 per ton concentrate, tailings management costs of $2.86 per ton processed, and water treatment expenses of $0.18 per ton processed with appropriate recovery and dilution factors.

 Piedmont's reserves at NAL experienced year over year changes due to the current year production which resulted in a depletion of proven and probable reserves. Additionally, in February 2024, Piedmont sold approximately 1,249,806,231 shares of Sayona Mining, which represented approximately 12% of Sayona Mining at the time of sale. With that sale, Piedmont no longer holds shares of Sayona Mining, and its ownership interest in NAL is derived solely from its ownership in Sayona Quebec, which remains at 25%. There were no year over year changes to reported resources at NAL. Piedmont's proportional share of resources decreased 26.5% due to our ownership change noted above.

 Internal Controls
 We have internal controls for reviewing and documenting the information supporting the mineral reserve and mineral resource estimates, describing the methods used, and ensuring the validity of the estimates. These internal control processes were not materially impacted by the adoption of S-K 1300. Information that is utilized to compile mineral reserves and mineral resources is prepared and certified by appropriate QPs and is subject to our internal review process, which includes review by a QP. The QP and management agree on the reasonableness of the criteria for the purposes of estimating resources and reserves. Calculations using these criteria are reviewed and validated by the QP. We recognize the risks inherent in mineral resource and reserve estimates, such as the geological complexity, interpretation and extrapolation of data, changes in operating approach, macroeconomic conditions and new data, among others. Overestimated resources and reserves resulting from these risks could have a material effect on future profitability.

 Cautionary Note to Investors
 In the U.S., we are governed by the Exchange Act, including Regulation S-K 1300 thereunder. Sayona Mining and Atlantic Lithium, however, are not governed by the Exchange Act and from time-to-time report estimates of "measured," "indicated," and "inferred" mineral resources as such terms are used in the JORC Code. In March 2022, our partner, Sayona Mining, published a JORC Code mineral resource estimate update for Authier, and most recently published a JORC Code mineral resource estimate update for NAL in August 2024. Although S-K 1300 and the JORC Code have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, they at times embody different approaches or definitions. The technical report summaries for Authier and NAL, attached as Exhibits 96.2 and 96.3, respectively, to this Annual Report are compliant with S-K 1300. Consequently, investors are cautioned that public disclosures of measures prepared in accordance with the JORC Code may not be comparable to similar information made public by companies subject to S-K 1300 and the other reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations thereunder.

 Executive Overview & Strategy
 We are a U.S.-based, development-stage company advancing a multi-asset, integrated lithium business in support of a clean energy economy and U.S. and global energy security. We plan to supply lithium hydroxide to the electric vehicle and battery manufacturing supply chains in North America by processing spodumene concentrate produced from assets we own or in which we have an economic interest.
 Since 2021, electric vehicle and battery companies have announced significant commitments to build new or expanded manufacturing operations across the U.S., which are expected to drive domestic demand for lithium far beyond current or projected capacity over the next decade. Piedmont Lithium, as a U.S.-based company, is well positioned to benefit from federal policies and funding established to facilitate the expedited development of a robust domestic supply chain and clean energy economy, while strengthening national and global energy security. Manufacturing facilities for electric vehicles, batteries, and related components are typically constructed in two to three years; however, the development of lithium resources from exploration to production requires a much longer time frame. We believe this prolonged time frame for resource development poses the greatest challenge to the emerging electrification industry and highlights the critical role of lithium producers.
 To support growing U.S. lithium demand, we have spent the past eight years developing a portfolio of three key projects: wholly-owned Carolina Lithium in North Carolina, and strategic investments in Quebec, Canada, with Sayona Quebec's NAL, and in Ghana, with Atlantic Lithium's Ewoyaa project. NAL began supplying spodumene concentrate to the market in the third quarter of 2023 and reached a steady run rate in the second quarter of 2024. Carolina Lithium is being developed as a fully integrated spodumene ore-to-lithium hydroxide project. During the third quarter of 2024, we made the decision to shift Tennessee Lithium's planned annual production capacity of 30,000 metric tons of lithium hydroxide to Carolina Lithium via a second production train in a phased development approach, which would allow Carolina Lithium to produce up to 60,000 metric tons of lithium hydroxide annually. Consolidating our U.S. lithium hydroxide production strategy positions Piedmont to leverage our foundational Carolina Lithium project and deploy capital and technical resources more efficiently.
 Our current plan to produce an estimated 60,000 metric tons per year of domestic lithium hydroxide would be significantly accretive to today's total estimated U.S. annual production capacity of approximately 20,000 metric tons per year. Our lithium hydroxide capacity and revenue generation are expected to be supported by production of, or offtake rights to, approximately 525,000 metric tons of spodumene concentrate annually.

 Our projects and strategic investments are being developed on a measured timeline based on prevailing market conditions to manage near-term cash while optimizing future cash flow and long-term value maximization. The development timelines are also subject to permitting, regulatory approvals, funding, and successful project execution.
 As we continue to advance our goal of becoming one of the leading manufacturers of lithium products in North America, we expect to capitalize on our competitive strengths, including our life-of-mine offtake agreement with Sayona Quebec, scale and diversification of lithium resources, advantageous locations of projects and assets, access to a variety of funding options, opportunities to leverage our greenfield projects, and a highly experienced management team. Advancements toward this effort are highlighted below.

 Highlights of Corporate and Project Advancements

 Piedmont Lithium
 We continue to engage in activities to strengthen our financial position and business strategy, including decisions to drive prudent capital deployment and cost savings that preserve assets within our portfolio of projects and strategic investments.
 Recent highlights include:
 • In 2024, Piedmont sold approximately 116,700 dmt of spodumene concentrate and recognized $99.9 million in revenue with a realized sales price of $856 per dmt and a realized costs of sales of $763 per dmt.
 • In September 2024, we entered into a working capital facility, whereby we may borrow up to $25.0 million based on the value of committed volumes of spodumene concentrate occurring within a twelve-month period. Prepayments, or borrowings, are credited against the outstanding prepayment balance at the time the vessel has completed loading. Interest is payable quarterly at the rate of SOFR plus 2.4%. The Credit Facility expires on September 11, 2027 with an option to extend to December 31, 2028. See Note 14—Debt Obligations to the audited consolidated financial statements included in this Annual Report.
 • In the fourth quarter of 2024, we completed our 2024 Cost Savings Plan with $14 million in annual cost savings achieved during the year. To achieve these savings, we reduced our workforce by 62% and lowered third-party spending consisting primarily of professional fees and other operating costs. We recorded $5.8 million in severance and restructuring related costs in 2024. We also achieved significant reductions in capital expenditures and investments in and advances to affiliates in 2024 as part of our cost savings efforts. We are carrying our cost and investment discipline into 2025 as we weather the current lithium market downcycle.
 • During the third quarter of 2024, we streamlined our U.S. lithium hydroxide production plans in favor of deploying capital and technical resources more efficiently by shifting our proposed Tennessee Lithium conversion capacity to Carolina Lithium. We plan to leverage Carolina Lithium by adding a second lithium hydroxide production train as part of a phased development approach to produce 60,000 metric tons of lithium hydroxide annually.

 Lithium Projects
 As of December 31, 2024, we owned an equity interest of 25% in Sayona Quebec. Sayona Mining owned the remaining 75% equity interest in Sayona Quebec. Sayona Quebec owns a portfolio of projects, which includes NAL, Authier, Tansim, and Vall e. We hold a life-of-mine offtake agreement with Sayona Quebec for the greater of 113,000 dmt or 50% of spodumene concentrate production per year. Our purchases of spodumene concentrate are subject to a price floor of $500 per dmt and a price ceiling of $900 per dmt for 6.0% Li2O spodumene concentrate.
 Recent highlights include:
 • During 2024, NAL achieved record production of 193,162 dmt of spodumene concentrate, shipped approximately 84,100 dmt to third parties, and sold approximately 116,700 dmt to Piedmont.
 • Production at NAL increased 96% in 2024 as compared to 2023. With the commissioning of the crushed ore dome in the second quarter of 2024, mill utilization increased to 90% in the fourth quarter of 2024, which is an increase of 20% from the fourth quarter of 2023.
 • During the third quarter of 2024, Sayona Mining announced an increase to the mineral resources estimate at NAL, which included a significant increase to the mineral resources in the measured & indicated categories in accordance with JORC Code requirements.

 Ghana
 As of December 31, 2024, we owned an equity interest of approximately 5% in Atlantic Lithium. We have a right to acquire a 50% equity interest in Atlantic Lithium Ghana, which includes Atlantic Lithium's flagship Ewoyaa project, located approximately 70 miles from the Port of Takoradi in Ghana, West Africa. We hold an offtake agreement with Atlantic Lithium for 50% of annual production of spodumene concentrate at market prices on a life-of-mine basis from Ewoyaa.
 Recent highlights include:
 • In July 2024, the application to grant the Ewoyaa mining lease was submitted to the Ghanaian parliament to undergo the ratification process. The mining lease remains subject to parliamentary ratification as of the date of this Annual Report.
 • In September 2024, Ghana's Environmental Protections Agency granted an environmental permit to the Ewoyaa project.
 • In October 2024, the Ghanaian Minerals Commission issued a Mine Operating Permit for the Ewoyaa project. The receipt of the permit marked an important milestone in achieving the regulatory approvals required to commence project construction. The project, however, remains subject to ratification of the mining lease by the Ghanaian Parliament, ongoing design work, additional regulatory approvals, prevailing market conditions, and project financing.

 Carolina Lithium is located in the historic Carolina Tin-Spodumene Belt and is being designed as a fully integrated project with mining, spodumene concentrate production, and lithium hydroxide manufacturing on a single site in Gaston County, North Carolina. At full production, Carolina Lithium is expected to produce 60,000 metric tons of lithium hydroxide annually.
 Based on our current technical studies, we expect Carolina Lithium to be a low-cost producer of spodumene concentrate and lithium hydroxide and a key contributor to U.S. energy security. The project should benefit from high-quality infrastructure, minimal transportation distances, low energy costs, a deep local talent pool, and proximity to cathode and battery customers as well as by-product markets. The competitive corporate tax regime offered in the U.S., the absence of material royalties, and the benefits inherent in the IRA are also expected provide advantages to the project.
 Management is actively engaging in discussions with potential strategic partners who have expressed interest in project-level funding for Carolina Lithium. Our goal through the partnership process is to advance the project through ongoing permitting and rezoning activities. We are considering the timing of the local rezoning process, which is dependent upon our funding strategy, potential partnerships, project development plans, and market dynamics. Engagement continues with community stakeholders, including the Gaston County Board of Commissioners in North Carolina. The Carolina Lithium funding strategy also includes potential government financing options.
 In May 2024, we received the finalized mining permit for the construction, operation, and reclamation of Carolina Lithium following the posting of a $1 million reclamation bond to the state of North Carolina. The NCDEQ approved the permit application on April 12, 2024.
 In October 2024, the U.S. Department of the Treasury issued final rules for the IRA's manufacturing credit (45X) with modifications intended to drive critical mineral processing in the U.S. The new rules support the application of a 10% manufacturing credit to direct and indirect material costs, which could materially improve the economics of U.S. projects like Carolina Lithium.

 Tennessee Lithium
 Tennessee Lithium was planned as a merchant lithium hydroxide manufacturing plant to produce 30,000 metric tons per year of lithium hydroxide. As part of our streamlined U.S. production strategy, we converted our proposed Tennessee Lithium project plans to a second lithium hydroxide train as part of a phased development approach for Carolina Lithium. The combined conversion facilities should allow us to significantly increase U.S. lithium hydroxide production capacity while deploying capital and technical resources more efficiently.

 As of December 31, 2024, we owned an equity interest of approximately 20% in Vinland Lithium, which is a Canadian-based entity jointly owned with Sokoman Minerals and Benton Resources. Vinland Lithium owns Killick Lithium, which owns a large exploration

 property prospective for lithium located in southern Newfoundland, Canada. As of December 31, 2024, we have invested $2.6 million in Killick Lithium.
 As part of our earn-in agreement with Vinland Lithium, we have the right to acquire up to a 62.5% equity interest in Killick Lithium through staged investments, which may be paid in cash or shares of our common stock. As part of our investment in Vinland Lithium, we entered into a marketing agreement with Killick Lithium for 100% marketing rights and the right of first refusal to purchase 100% of all lithium products produced by Killick Lithium on a life-of-mine basis at competitive market prices.

 Market Outlook
 The demand for electric vehicles continues to grow as many jurisdictions around the world have legislated the shifting of new car fleets away from internal combustion engines and toward electric vehicles. These electric vehicles will use batteries, nearly all of which are expected to be lithium-based batteries. Our strategy is to develop resources and processing capabilities that support the opportunity to meet the demands of our customers across the electric vehicle supply chain. Car manufacturers have committed significant capital investments totaling more than $1 trillion across the electric vehicle supply chain to electrify their fleets. Many of the major car manufacturers have plans to build facilities in the U.S. to produce both lithium-ion batteries and electric vehicles that will require a supply of lithium products.
 Lithium products are expected to be in a supply deficit in the coming years due to the projected adaption to electric vehicles as presented in the graph below:

 Components of our Results of Operations
 We recognize revenue from product sales at a point in time when performance obligations are satisfied under the terms of contracts with our customers. A performance obligation is deemed to be satisfied when control of the product is transferred to our customer, which is typically upon delivery to the shipping carrier. Where a contract contains more than one distinct performance obligation, the transaction price is allocated to each performance obligation based on the standalone selling price of each performance obligation, although these situations do not occur frequently and are generally not built into our contracts. Revenue is measured as the amount of consideration expected to be received in exchange for transferring the products to our customers. Some contracts contain prepayment provisions which allow the customer to secure the right to receive their requested product volumes in a future period. Revenue from these contracts is initially deferred, thus creating a contract liability. Initial pricing is typically billed 5 days to 30 days after the departure of the shipment and is paid between 15 days to 75 days after the departure of the shipment. Final adjustments to prices may take longer to resolve. When the final price has not been resolved by the end of a reporting period, we estimate the expected sales price based on the initial price, market pricing, and known quality measurements. We warrant to our customers that our products conform to mutually agreed product specifications.
 Exploration Costs
 We incur costs in resource exploration, evaluation, and development during the different phases of our resource development projects. Exploration costs incurred before the declaration of proven and probable mineral reserves, which primarily include exploration, drilling, engineering, metallurgical testwork, site-specific reclamation, and compensation for employees associated with exploration activities, are expensed as incurred. After proven and probable mineral reserves are declared, exploration and mine development costs necessary to bring the property to commercial capacity or increase the capacity or useful life are capitalized.
 Selling, General and Administrative Expenses
 Selling, general and administrative expenses relate to overhead costs, such as employee compensation and benefits for corporate management and office staff including accounting, legal, human resources, and other support personnel, professional service fees, insurance, and costs associated with maintaining our corporate headquarters. Included in employee compensation costs are cash and stock-based compensation expenses.
 Restructuring and Impairment Charges
 Restructuring, impairment, and other exit costs represent expenses incurred in connection with certain cost reduction programs that we have implemented, and consists of the costs of asset impairments, employee termination costs, lease and other contract termination charges and other costs of exiting activities. A liability for costs associated with an exit or disposal activity is measured at its fair value when the liability is incurred. Expenses for one-time termination benefits are recognized at the date the employee is notified, unless the employee must provide future service, in which case the benefits are expensed ratably over the future service period. Liabilities related to termination of an operating lease or contract are measured and recognized at fair value when the contract does not have any future economic benefit to the entity and the fair value of the liability is determined based on the present value of the remaining lease obligations, adjusted for the effects of deferred items recognized under the lease, and reduced by estimated sublease rentals that could be reasonably obtained for the property. The assumptions in determining such estimates include anticipated timing of sublease rentals and estimates of sublease rental receipts and related costs based on market conditions. All other costs related to an exit or disposal activity are expensed as incurred. Refer to Note 6—Restructuring and Impairment for further information.
 Loss From Equity Method Investments
 Loss from equity method investments reflects our proportionate share of the net income (loss) resulting from our current and legacy investments in Sayona Mining, Sayona Quebec, Vinland Lithium, and Atlantic Lithium. Investments recorded under the equity method are adjusted each period, on a one-quarter lag, for our share of each investee's income (loss). If a decline in the value of an equity method investment is determined to be other than temporary, we record any related impairment as a component of our share of earnings or losses of the equity method investee in the current period. Our equity method investments are an integral and integrated part of our ongoing operations. We have determined this justifies a more meaningful and transparent presentation of our proportional share of income (loss) in our equity method investments as a component of our income (loss) from operations.

 Other Income (Loss)
 Other income (loss) consists of interest income, interest expense, foreign currency exchange gain (loss), gain (loss) on equity securities, gain (loss) on sale of assets, and gain (loss) on sale of equity method investments. Interest income consists of interest earned on our cash and cash equivalents. Interest expense consists of interest incurred on long-term debt related to noncash acquisitions of mining interests financed by sellers for Carolina Lithium as well as interest incurred for lease liabilities. Foreign currency exchange gain (loss) primarily relates to our foreign bank accounts denominated in Canadian dollars and Australian dollars and marketable securities denominated in Australian dollars. Gain (loss) on equity securities relates to realized and unrealized gains (losses) of our investments in marketable and equity securities. Gain (loss) on sale of assets primarily relates to our sale or disposal of property, plant and mine development assets. Gain (loss) on sale of equity method investments relates to our reduction in ownership in Sayona Mining and Atlantic Lithium due to: (i) gain (loss) on dilution due to their issuance of additional shares through public offerings and employee stock compensation grants while they were accounted for under the equity method, and; (ii) gain (loss) on the sale of shares of our equity method investments.

 Revenue increased $60.1 million, or 150.8%, to $99.9 million in the year ended December 31, 2024 as compared to $39.8 million in the year ended December 31, 2023. Sales volume of spodumene concentrate increased approximately 73,400 dmt, or 169.5%, to approximately 116,700 dmt in the year ended December 31, 2024 as compared to approximately 43,300 dmt in the year ended December 31, 2023. The increase in revenue was due to the increase in sales volume as sales of spodumene concentrate commenced in September 2023. All revenue was generated from sales of spodumene concentrate, which was produced at NAL and purchased as part of our purchase offtake agreement with Sayona Quebec.
 Our realized prices were $856 per dmt of spodumene concentrate (approximately 5.4% Li2O grade) and $920 per dmt of spodumene concentrate (approximately 5.5% Li2O grade) for the years ended December 31, 2024 and 2023, respectively. The decline in lithium prices resulted in realized prices declining $64 per dmt, or 6.9%, in the year ended December 31, 2024 as compared to the year ended December 31, 2023.
 Realized price is the average estimated price, net of certain distribution and other fees, and includes referenced pricing data up to December 31, 2024 and 2023 for the years ended December 31, 2024 and 2023, respectively, and may be subject to final adjustment. For certain contracts, the final adjusted price may be higher or lower than the average estimated realized price based on future market price movements. For contracts where final pricing has yet to be determined, we estimate the final sales price based on expected market conditions and known quality measurements for purposes of revenue recognition and disclosure of realized prices. Any adjustments to the sales price will be reflected in subsequent periods.

 Gross Profit and Gross Profit Margin
 Gross profit increased $5.1 million, or 90.1%, to $10.8 million in the year ended December 31, 2024 as compared to $5.7 million in the year ended December 31, 2023. Gross profit margin declined to 10.8% in the year ended December 31, 2024 compared to 14.3% in the year ended December 31, 2023. The increase in gross profit was due to a full year of sales volume in the year ended December 31, 2024 as compared to four months of sales volume in the year ended December 31, 2023. The decrease in gross profit margin was due to the decline in lithium prices as part of the continued lithium market downturn as well as our preferential offtake agreement which includes a price ceiling of $900 per dmt for 6.0% Li2O spodumene concentrate. Our cost of sales was at the $900 ceiling price for the year ended December 31, 2023 and for the first half of the year ended December 31, 2024, which drove higher gross profit margins during these time periods.
 Our realized costs of sales were $763 per dmt of spodumene concentrate and $789 per dmt of spodumene concentrate in the years ended December 31, 2024 and 2023, respectively. Realized costs of sales is the average costs of sales based on our offtake pricing agreement with Sayona Quebec for the purchase of spodumene concentrate at a market price subject to a floor of $500 per dmt and a ceiling of $900 per dmt, with adjustments for product grade, and freight.
 Exploration Costs
 Exploration costs decreased $1.8 million, or 95.0%, to $0.1 million in the year ended December 31, 2024 as compared to $1.9 million in the year ended December 31, 2023. The decrease in exploration costs was primarily driven by a decrease in exploration and engineering activities related to new project targets. As part of our 2024 Cost Savings Plan, we have substantially reduced, or in certain cases eliminated, exploration costs in response to the lithium market downturn.
 Selling, General and Administrative Expenses
 Selling, general and administrative expenses decreased $4.6 million, or 10.7%, to $38.7 million in the year ended December 31, 2024 as compared to $43.3 million in the year ended December 31, 2023. The decrease in selling, general and administrative expenses was primarily due to cost savings recognized as part of our 2024 Cost Savings Plan, which included lower professional and consulting fees and lower employee compensation costs and travel costs in connection with our workforce reduction during 2024. Partially offsetting the decrease in selling, general and administrative expenses was an increase associated with professional and consulting fees for our pending Merger with Sayona Mining totaling $6.9 million and $1.3 million in the years ended December 31, 2024 and 2023, respectively. Stock-based compensation expense included in selling, general and administrative expenses was $8.0 million and $9.4 million in the years ended December 31, 2024 and 2023, respectively.
 (Loss) Income from Equity Method Investments
 Loss from equity method investments increased $18.0 million to a loss of $17.8 million in the year ended December 31, 2024 as compared to income of $0.2 million in the year ended December 31, 2023. The loss of from equity method investments of $17.8 million in the year ended December 31, 2024 reflects our proportionate share of loss resulting from our equity investments in Sayona Mining, Sayona Quebec, Atlantic Lithium, and Vinland Lithium. The income from equity method investments of $0.2 million in the year ended December 31, 2023 reflects our proportionate share of income from Sayona Quebec, partially offset by our proportionate share of net loss from Sayona Mining, and Atlantic Lithium as well as an impairment charge of $2.2 million related to our investment in Sayona Mining. Our interest in Vinland Lithium was acquired in October 2023. See Note 11—Equity Method Investments for further information on our equity method investments.
 Restructuring and Impairment Charges
 We initiated our 2024 Cost Savings Plan in the first quarter of 2024. As part of our 2024 Cost Savings Plan, we recognized restructuring and impairment charges of $9.9 million in the year ended December 31, 2024. Restructuring and impairment charges consisted of $4.1 million in impairment charges related to land, capitalized construction and development costs, and other fixed assets related to Tennessee Lithium, $2.5 million in severance and employee benefits costs, $0.9 million in exit costs related to the planned exit of our monofill disposal facility in Etowah, Tennessee, and the consolidation of our corporate office to a single location in Belmont, North Carolina, $2.2 million in stock-based compensation related to accelerated vesting of certain stock-based compensation awards in connection with our workforce reduction, and $0.1 million in other restructuring related expenses. There were no restructuring or impairment charges in the year ended December 31, 2023.

 Other (Expense) Income
 Other (expense) income increased $32.9 million, or 159.0%, to other expense of $12.2 million in the year ended December 31, 2024 as compared to other income of $20.7 million in the year ended December 31, 2023. The increase in other expense was driven by our loss on sale of equity method investments related to Sayona Mining of $17.2 million in the year ended December 31, 2024 as compared to a gain on dilution related to Sayona Mining of $17.0 million in the year ended December 31, 2023. Other expense for the year ended December 31, 2024 also included a loss on the sale of assets of $0.8 million. The current year loss was partially offset by a gain on sale of equity method investments related to Atlantic Lithium of $3.1 million, and an unrealized gain on mark-to-market securities of $0.8 million. Interest income decreased $0.8 million primarily due to lower cash balances and interest expense increased $1.0 million primarily due to higher debt balances.
 Income Tax (Benefit) Expense
 Income tax benefit was $3.1 million in the year ended December 31, 2024 as compared to income tax expense of $3.1 million in the year ended December 31, 2023. The increase in income tax benefit was mainly due to the tax benefit generated from the loss on equity investments related to the sale of our entire equity interest in Sayona Mining in the year ended December 31, 2024.

 Liquidity and Capital Resources
 As of December 31, 2024, our principal sources of liquidity were cash and cash equivalents of $87.8 million and a fully-utilized Credit Facility totaling $25.0 million. Cash and cash equivalents consisted of institutional insured liquid deposits and cash deposit accounts. The vast majority of our cash and cash equivalents were held in the U.S. and covered by FDIC insured limits. Our predominant source of cash to date has been generated through equity financing from issuances of our common stock. We have a universal shelf registration statement which allows us to issue up to $500 million of securities as of December 31, 2024, and expires on September 26, 2027. During the second quarter of 2024, we entered into an ATM Program with a registered agent for potential, future issuances of our common stock under our shelf registration statement. As of the date of this filing, we have not issued common stock under our ATM Program. There are many factors that could significantly impact our ability to raise funds through equity and debt financing as well as influence the timing of future cash flows.
 Our primary uses of cash during the year ended December 31, 2024 consisted of: (i) settlement payments totaling $29.2 million in the first half of 2024 associated with spot shipment sales of spodumene concentrate in 2023 as a result of a decline in lithium prices; (ii) equity investments in Sayona Quebec mainly for capital expenditures at NAL related to the completion of a crushed ore dome and finalization of its operational restart totaling $15.0 million; (iii) advances to Atlantic Lithium primarily for exploration and evaluation activities, certain development activities, and permitting and approval activities related to our investment in Ewoyaa totaling $10.6 million; (iv) capital expenditures primarily related to engineering costs of $4.5 million for Tennessee Lithium; (v) development expenditures of $2.9 million and purchases of real property and associated mining interests of $3.2 million associated with Carolina Lithium; (vi) cash expenditures associated with our 2024 Cost Savings Plan of $2.6 million; and (vii) general and administrative costs related to our corporate expenses.
 On September 11, 2024, we entered into a Credit Facility that enables us to borrow up to $25.0 million. The Credit Facility expires on September 11, 2027 but may be extended through December 31, 2028. Borrowings are based on future, committed volumes of spodumene concentrate. Interest is payable quarterly at the rate of SOFR plus 2.4%. In the event we experience a material change in creditworthiness, the lender has the right to modify the payment terms of the Credit Facility including acceleration of repayment up to the full amount of any outstanding borrowings.
 During the first quarter of 2024, we initiated the 2024 Cost Savings Plan to reduce annual operating spend by $10.0 million mainly within our corporate expenses, defer capital spending to 2025 and beyond, and limit cash investments in and advances to affiliates. We achieved our $10 million annual run-rate target during the second quarter of 2024 through a 28% workforce reduction in the first quarter of 2024 and lowering of third-party spending consisting primarily of professional fees and other operating costs. Due to the prolonged lithium market downturn, we expanded our 2024 Cost Savings Plan and further reduced our workforce, including operational and corporate staff, by 32% in October 2024 and expect to achieve an additional $4 million in annual savings for a total of $14 million in annual costs savings. As part of our 2024 Cost Savings Plan, we reduced our total workforce by 62% and recorded $5.8 million in severance and restructuring related costs in the year ended December 31, 2024. We completed our 2024 Cost Savings Plan during the fourth quarter of 2024. See Note 6—Restructuring and Impairment to the audited consolidated financial statements included in this Annual Report for additional information regarding restructuring charges.

 To bolster our cash position and further strengthen our balance sheet, we monetized certain non-core assets during the year ended December 31, 2024. During the first quarter of 2024, we sold our common stock holdings in Sayona Mining and a portion of our common stock holdings in Atlantic Lithium for net proceeds totaling $49.1 million. The sale of our equity interests had no impact on our joint ventures or offtake rights with either Sayona Quebec and its NAL operations or the Ewoyaa project with Atlantic Lithium.
 Cash and cash equivalents increased $16.1 million, or 22.5%, to $87.8 million as of December 31, 2024 as compared to $71.7 million as of December 31, 2023.
 Liquidity Outlook
 Our planned cash expenditures for the next twelve months primarily relate to: (i) working capital requirements mainly associated with purchases of spodumene concentrate from NAL and our corporate costs, (ii) continued equity investments in Sayona Quebec for NAL; (iii) continued cash advances to Atlantic Lithium for Ewoyaa; and (iv) real property and associated mineral rights acquisition costs for Carolina Lithium; and (v) costs associated with our planned Merger with Sayona Mining.
 In 2025, we plan to deliver customer shipments of spodumene concentrate totaling 113,000 dmt to 130,000 dmt and fund capital expenditures totaling $6.0 million to $9.0 million and investments in and advances to affiliates totaling $7.0 million to $13.0 million. These full-year funding ranges reflect a substantial decrease in capital expenditures and joint venture funding compared to the full-year 2024. Our outlook for planned capital expenditures and investments in and advances to affiliates is subject to market conditions.
 As of December 31, 2024, we have entered into land option agreements in North Carolina totaling $13.7 million with current payment schedules as follows: $7.1 million in 2025, $6.4 million in 2026, $0.02 million in 2027, $0.02 million in 2028, and $0.2 million thereafter. These amounts do not include closing costs such as attorneys' fees, taxes, and commissions. We are not obligated to exercise our land option agreements, and we are able to cancel our land acquisition contracts, at our option with de minimis cancellation costs, during the contract option period. Due to current market conditions, we expect to defer to 2026 and beyond the purchase of the majority of our land option agreements coming due in 2025. If we are unsuccessful in deferring certain land purchases, we may decide to cancel certain option agreements for land purchases. We are evaluating these option agreements, and the decision to exercise will be influenced by market conditions and other relevant factors that align with our Company's long-term growth strategy. Certain land option agreements and land acquisition contracts become binding upon commencement of construction for Carolina Lithium. We terminated our agreements to acquire land in Tennessee during the third quarter of 2024.
 Based on our operating plan, which includes our fully implemented 2024 Cost Savings Plan and ongoing access to and utilization of the Credit Facility discussed above, we believe our cash on hand will be sufficient to fund our operations and meet our obligations as they come due for the twelve months following the date our consolidated financial statements are issued. Additionally, we expect to finance our future cash requirements, including the funding of our lithium projects, through a combination of strategic partnerships, non-core asset sales, equity offerings, and debt financings. Our operating plan and expectation of future financings include estimates and assumptions that may prove to be wrong or may need to modified due many factors, including lithium pricing. As a result, we could deplete our capital resources sooner than we currently expect. No assurances can be given that any additional cost reduction strategies or anticipated funding would be sufficient to meet our needs.
 We are evaluating a range of funding options to fund our share of project capital and maintaining a critical focus on funding options that would be non-dilutive to Piedmont Lithium's shareholders. We plan to utilize two main funding strategies for the construction of Carolina Lithium including an ATVM loan (upon a successful application and receipt of loan from the DOE's Loan Programs Office) and a strategic partnering process. Construction of Carolina Lithium is not planned to commence until project financing has been finalized. We have mandated a financial advisor as part of our funding strategy for our share of development capital for Ewoyaa. Our strategy includes the offering of a long-term offtake agreement in exchange for funding to support our capital contribution on a non-dilutive basis to our shareholders.
 Our long-term success is dependent upon our ability to successfully raise additional capital or financing or enter into strategic partnership opportunities. Our long-term success is also dependent upon our ability to obtain certain permits and approvals, develop our planned portfolio of projects, earn revenues, and achieve profitability. If we are unable to obtain funding, we would be forced to delay, reduce, or eliminate some or all of our exploration and development activities and joint ventures, which could adversely affect our business prospects and ultimately our ability to operate.
 Currently, there are no plans for future cash distributions from any of our equity method investments.
 Historically, we have been successful raising cash through equity financing. If we were to issue additional shares of our common stock, it would result in dilution to our existing shareholders. No assurances can be given that any additional financings would be

 available in amounts sufficient to meet our needs or on terms that would be acceptable to us. See Part I, Item 1A, "Risk Factors" in this Annual Report.

 Cash Flows from Operating Activities
 Operating activities used $42.9 million and provided $1.6 million in the year ended December 31, 2024 and 2023, respectively, resulting in an increase in cash used by operating activities of $44.5 million. The increase was mainly due to an increase of $46.1 million in working capital outflows, primarily driven by $29.2 million in settlement payments in 2024 associated with spot shipment sales of spodumene concentrate in 2023 as a result of a decline in lithium prices. In addition, we had an decrease in net loss of $1.7 million, net of certain noncash items including gain (loss) on sale of equity method investments, impairment of fixed assets, loss from sale of assets, loss from equity method investments, stock compensation expense, gain on marketable securities, and deferred taxes.
 Cash Flows from Investing Activities
 Investing activities provided $12.7 million and used $99.3 million in the year ended December 31, 2024 and 2023, respectively, resulting in an increase in cash provided by investing activities of $112.0 million. The increase was due to (i) the receipt of $49.1 million in net proceeds from the sale of our entire equity interest in Sayona Mining and the partial sale of our equity interest in Atlantic Lithium, (ii) a decrease in capital expenditures of $46.0 million, and (iii) a decrease in contributions to equity investments of $18.3 million. Partially offsetting the decrease in cash used for investing activities was an increase in cash advances totaling $1.5 million to Atlantic Lithium and Vinland Lithium for project advances to Ewoyaa and Killick Lithium, respectively.
 Cash Flows from Financing Activities
 Financing activities provided $46.3 million and $70.2 million in the year ended December 31, 2024 and 2023, respectively, resulting in a decrease in cash provided by investing activities of $23.9 million. The decrease in cash from financing activities was driven by a $46.5 million decrease in net cash proceeds from issuances of our common stock in the year ended December 31, 2024 compared to the year ended December 31, 2023. In February 2023, we received net proceeds of $71.1 million from LG Chem in exchange for 1,096,535 shares of our common stock in conjunction with a multi-year spodumene concentrate offtake agreement. In November 2024, we received net proceeds of $24.6 million through a private placement of 2,380,953 shares of our common stock. In addition, payments to tax authorities for employee share-based compensation and payments on debt and financing arrangements increased $0.4 million and $2.0 million, respectively, compared to the prior year period. These decreases were partially offset by an net increase of $25.0 million in proceeds from the Credit Facility.

 Contractual Obligations and Other Commitments

 Although we have entered into certain offtake supply agreements, purchase obligations from our customers are defined as purchase agreements that are enforceable and legally binding and specify all significant terms, including quantity, price, and the approximate timing of the transaction. Our obligations to fulfill supply agreements do not meet these criteria and are therefore not reflected in the table above.

 Off-Balance Sheet Arrangements
 In 2023, we purchased a 132-acre disposal facility adjacent to the proposed Tennessee Lithium plant site for the placement of inert tailings produced as part of the innovative alkaline pressure leach process. The Tennessee Department of Environment and Conservation requires that closure and post-closure obligations of the disposal facility be covered by a surety bond. Surety bonds securing closure and post-closure obligations at December 31, 2024 and 2023 totaled $ 3.3 million and $ 3.2 million, respectively.

 Critical Accounting Policies and Estimates
 Our management's discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
 While our significant accounting policies are described in the notes to our consolidated financial statements included elsewhere in this Annual Report, we believe that the following critical accounting policies are most important to understanding and evaluating our reported financial results.
 For certain of our sales of spodumene concentrate, customer contracts allow for pricing based on a period of time subsequent to shipping, which in most cases is within the following four months. In such cases, revenue is recorded at a provisional price at the time of shipment. Provisionally priced sales are adjusted to reflect market prices at the end of each month until a final adjustment is made to the price of the shipments upon settlement with customers pursuant to the terms of the contract.
 Stock-based Compensation
 The Leadership and Compensation Committee generally grants stock-based awards in the first quarter of each year. The Leadership and Compensation Committee does not have any programs, plans, or practices of timing these awards in coordination with the release of material non-public information. We have not backdated, re-priced, or spring-loaded any of our stock-based awards.
 Equity-settled, share-based payments may be provided to officers, employees, consultants and other advisors. These share-based payments are measured at the fair value of the equity instrument at the grant date. Fair value of share options is determined using the Black-Scholes option pricing model, taking into account the terms and conditions upon which the instruments were granted, and are disclosed in Note 4—Stock-Based Compensation to the audited consolidated financial statements appearing elsewhere in this Annual Report. Fair value of TSR PRAs is determined using a Monte Carlo simulation. The Monte Carlo simulation fair value model requires the use of highly subjective and complex assumptions, including the price volatility of the underlying stock. A Monte Carlo simulation

 model was used to determine the grant date fair value by simulating a range of possible future stock prices for the Company and each member of the peer group over the performance period is disclosed in Note 4—Stock-Based Compensation to the audited consolidated financial statements appearing elsewhere in this Annual Report.
 We record stock-based compensation expense within exploration costs, general and administrative expenses, and restructuring and impairment charges in the consolidated statements of operations. Costs are allocated among those receiving the benefit based upon job function. There are certain employees who serve both functions, and therefore, their stock-based compensation expense is split between both financial statement lines in the consolidated statements of operations.
 Estimating fair value for share-based payment transactions requires determination of the most appropriate valuation model, which depends on the terms and conditions of the grant. This estimate also requires determination of the most appropriate inputs to the valuation model including the expected life of the share option, volatility, dividend yield, and risk-free interest rate and making assumptions about them.
 Changes to these inputs would impact the consequent valuation for each equity instrument valued in this manner, and consequently, the value of each grant would vary in a different manner depending on the change to the respective inputs.
 The fair value determined at the grant date is expensed on a straight-line basis over the vesting period, which is based on our estimate of equity instruments that will eventually vest. At each reporting date, we revise our estimate of the number of equity instruments expected to vest. The impact of the revision of the original estimates, if any, is recognized in profit or loss over the remaining vesting period, with a corresponding adjustment to the share-based payments reserve.
 Investments in Unconsolidated Entities
 We strategically invest in unconsolidated entities that we believe will provide us access to hard rock lithium assets as well as projects with the potential for scale, low-cost, sustainable production practices and that are strategically located to our proposed lithium hydroxide manufacturing sites.
 Our unconsolidated entities are accounted for by the equity method of accounting because we have a significant influence, but not control, in the investee. We record our investments in these entities in our consolidated balance sheets as "Equity method investments" and our pro-rata share of the entities' earnings or losses in our consolidated statements of operations as "(Loss) income from equity investments."
 We look at specific criteria and use our judgment when determining if we have a controlling interest in a less than wholly-owned entity. Factors considered in determining whether we have significant influence, or we have control, include, but are not limited to, ownership percentage, the ability to appoint individuals to the investee's board of directors, operational decision-making authority, and participation in policy-making decisions. The accounting policy relating to the use of the equity method of accounting is a critical accounting policy due to the judgment required in determining whether we have significant influence over the entity.

 Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
 Interest Rate Risk
 Our exposure to the risk of changes in market interest rates relates primarily to our variable rate debt, and cash and short-term deposits with a floating interest rate. As of December 31, 2024 and 2023, we had $87.8 million, and $71.7 million, respectively, of cash and short-term deposits. Our cash and short-term deposits do not expose us to material cash flow interest rate risk. Total variable rate debt as of December 31, 2024 was $25.0 million with a variable interest rate of SOFR + 2.4%. A 1.0 percentage point change in interest rates on variable rate debt would have resulted in annual interest expense fluctuating by approximately $0.2 million. We currently do not engage in any hedging or derivative transactions to manage interest rate risk. All other financial assets and liabilities, in the form of payables, lease liabilities, and long-term debt, are fixed rate or non-interest bearing.
 Foreign Currency Risk
 Our provisional spodumene concentrate sales are calculated, in part, based on the foreign exchange rate between the U.S. dollar and the Chinese renminbi over applicable quotational periods, and therefore, we are exposed to currency volatility and devaluation risks. Geopolitical tensions between the U.S. and China may lead to increased tariffs, preferences for local producers, some of which may be government supported, or other trade barriers. The economic impact of currency exchange rate movements is often linked to variability in real growth, inflation, interest rates, governmental actions, and other factors. While foreign currency risk has not had a

 material impact on our results of operations, we continue to evaluate our risk exposure and may enter into hedging transactions to manage our exposure to fluctuations in foreign currency exchange rates.
 Commodity Price Risk
 Our results of operations are dependent upon the market prices of lithium products. These lithium products are not quoted on any major commodities market or exchange as these product's attributes vary and demand is currently constrained to a relatively limited number of purchasers, a significant majority of which are based in China. Market prices published for lithium products can be volatile and are influenced by numerous factors, including international, economic, and political trends, expectations of inflation, currency exchange fluctuations, interest rates, global or regional consumptive patterns, speculative activities, increased production due to new extraction developments, and improved extraction and production methods and technological changes in the markets for the end products.
 We have utilized the services of a trading partner to enter into hedging transactions on our behalf to manage our exposure to fluctuations in the market prices of lithium products. We will continue to evaluate our options moving forward as the futures market for lithium products further develops.
 During the year ended December 31, 2024, we received provisional payments on sales of 39,255 dmt of spodumene concentrate under provisional pricing arrangements. There are 24,350 dmt of spodumene concentrate that remain subject to final pricing determinations at year-end. The price per metric ton is calculated based on multiple factors, including the average applicable market price index over the applicable quotational period. We recognize revenue from product sales at a point in time when performance obligations are satisfied under the terms of contracts with our customers. When the final price has not been resolved by the end of a reporting period, we estimate the expected sales price based on the initial price, market pricing and known quality measurements. Differences between payments received and the final estimated sales price, which results in a liability, are recorded as accrued provisional revenue adjustments.
 We conduct a sensitivity analysis on our provisional concentrate sales still subject to final pricing to determine the potential impact to net income (loss) of a 10% change to the applicable market price index as compared to the applicable market price index as of December 31, 2024. Such a 10% change yields a potential impact of approximately $1.8 million to net income (loss).
 Additionally, market prices of lithium products affect the economic feasibility of mining on our properties, the value of such properties and the potential timing of construction of Carolina Lithium.

 Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
 See "Index to Consolidated Financial Statements" beginning on page F-1 of this Annual Report, which information is incorporated by reference into this Item 8.

 Item 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.
 None.

 Item 9A. CONTROLS AND PROCEDURES.
 Evaluation of Disclosure Controls and Procedures
 Our management, under supervision and with the participation of our CEO (our Principal Executive Officer) and CFO (our Principal Financial Officer and Principal Accounting Officer), evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of December 31, 2024. Based on the evaluation of our disclosure controls and procedures, our CEO and CFO have concluded that our disclosure controls and procedures were effective as of December 31, 2024.
 Management's Annual Report on Internal Control Over Financial Reporting
 Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. These rules define internal control over financial reporting as a process designed by,

 or under the supervision of, a company's CEO and CFO and effected by our Board, management, and other personnel, 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 and includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.
 Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2024. This assessment was performed under the direction and supervision of our CEO and CFO and based on criteria established in Internal Control-Integrated Framework (2013) issued by COSO. Our management's assessment of the effectiveness of our internal control over financial reporting included testing and evaluating the design and operating effectiveness of our internal controls. Based on this assessment, and criteria established in the COSO 2013 framework, management has concluded that we maintained effective internal control over financial reporting as of December 31, 2024.
 Inherent Limitations of Internal Controls
 Our management, including our CEO and CFO, does not expect that our disclosure controls and procedures or our internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. 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. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements due to error or fraud.
 Changes in Internal Control over Financial Reporting
 Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate annually the effectiveness of our internal controls over financial reporting as of the end of each fiscal year, and to include a management report assessing the effectiveness of our internal control over financial reporting in all annual reports. There were no changes in our internal control over financial reporting during the quarter ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

 Item 9B. OTHER INFORMATION.

 Item 9C. DISCLOSURE REGARDING FOREIGN JURISDICTIONS THAT PREVENT INSPECTIONS.
 None.

 Base Salary
 The purpose of base salary, from the perspective of the Leadership and Compensation Committee, is to compensate our NEOs fairly and competitively with a fixed amount of cash for the jobs they perform. In addition, base salaries are used to recognize the experience, skills, knowledge, and responsibilities required of our NEOs. Accordingly, we seek to ensure that base salary levels are competitive and consistent with industry practices and peers. Base salaries are reviewed annually based on job responsibilities, experience, individual performance, and market competitiveness.

 Performance-Based Annual Cash Bonus
 The 2024 cash bonus scorecard was comprised of individual objectives (20% weighting) and Company strategic goals (80% weighting). Total payout under the 2024 cash bonus scorecard ranges from 0% to 200% of the target annual bonus amount for each NEO, with a 50% payout for threshold performance and a 200% payout for maximum performance.

 LONG-TERM EQUITY INCENTIVE AWARDS
 Long-term equity incentive awards in 2024 consisted of RSUs (25%), PRAs (50%), and premium-priced stock options (25%). Our compensation program uses these equity-based awards, the ultimate value of which is contingent on our longer-term performance, to provide NEOs with a direct incentive to seek increased stockholder returns. We believe this aligns the interests and actions of our NEOs with the interests of the Company's stockholders. The RSUs granted in 2024 vest in equal installments on each of December 31, 2024, 2025, and 2026, and the premium-priced stock options vest on December 31, 2026.

 2024 PRAs
 PRAs based on relative TSR create a direct link between pay and performance by tying the number of earned PRAs to the TSR realized by our stockholders relative to the specified TSR peer group. Awards vest in three equal tranches based on our TSR relative to the TSR of our specified peer group ranging from 0% to 200% of target over one-, two-, and three-year performance periods ending on December 31, 2024, 2025, and 2026. The earned PRAs vest on December 31, 2025, with respect to the first two performance periods, and December 31, 2026, with respect to the last performance period.
 The number of PRAs that become earned for each one-third tranche is determined by ranking each member of the relative TSR peer group from highest to lowest TSR without inclusion of Piedmont. Piedmont's TSR is then compared to the TSR peer group to determine the Company's percentile rank and the resulting payout percentage, as set forth below (with straight-line interpolation for any attained percentile between two of the levels):

 Performance of Tranche 1 of 2024 PRAs
 These 2024 PRAs were based on the Company's TSR performance relative to the TSR peer group during the one-year performance period ending December 31, 2024, which has not yet been certified by the Leadership and Compensation Committee. The earned 2024 PRAs vest on December 31, 2025, subject to approval of performance level by the Leadership and Compensation Committee and the NEO's continued service with the Company.
 Performance of Tranche 2 of 2023 PRAs
 Following the end of the performance period for the second one-third tranche of the 2023 PRAs, which ended December 31, 2024, the Leadership and Compensation Committee reviewed the Company's TSR ranking relative to the TSR for each member of the TSR peer group, resulting in a shares payout percentage of 86% of target as a result of the Company's TSR ranking at the 43rd percentile of the TSR peer group. These PRAs vested on December 31, 2024.
 Performance of 2022 Operational PRAs
 The 2022 PRAs granted to the NEOs were eligible to vest upon the achievement of corporate milestones prior to December 31, 2024. On August 10, 2023, the Leadership and Compensation Committee determined that the milestone related to the release of a comprehensive announcement of a positive DFS of Ewoyaa was achieved, and as such, 25% of the 2022 PRAs vested for each NEO. On August 9, 2023, the Leadership and Compensation Committee determined that the milestone related to the first commercial shipment of spodumene concentrate from NAL was achieved, and as such, 25% of the 2022 PRAs vested for each NEO. The remaining 50% of the 2022 PRAs held by each NEO s were not achieved and expired on December 31, 2024.

 STOCK OWNERSHIP GUIDELINES
 To ensure executive and stockholder interests are adequately aligned, we require NEOs to own significant amounts of Piedmont stock, as shown below. The required amounts are set at multiples of base salary. Executives have five years from the time the guidelines

 were adopted or, if later, the time they are first hired or promoted into a position at the executive vice president level or above to meet the guideline requirement.
 The number of shares of Company stock that must be held depends upon the executive officer's base salary on the date of hire, date of promotion, or the Company's defined measurement date. Our annual defined measurement date is January 2 (or the next trading date, if such date is not a trading date), date of hire, or date of promotion, whichever is most relevant. As of December 31, 2024, Mr. Phillips and Mr. White were on track to comply with their 5x base and 2x base salary requirements, respectively. Mr. Brindle ceased to be subject to the ownership requirements following his retirement on December 31, 2024.
 Shares owned by the executive officers directly or indirectly (e.g., by a spouse, minor child, or trust) and time-based restricted stock and RSUs are credited towards the stock ownership guidelines. PRAs, other performance-based awards, and stock options (whether vested or unvested) do not count toward stock ownership guidelines. Until the executive officer holds the requisite number of shares of Company stock, the executive officer may not sell more than 50% of the shares, net of shares sold for applicable withholding taxes, acquired from the settlement of stock awards or from the exercise of stock options. However, prior to meeting stock ownership guidelines, an executive officer is permitted to sell, without restriction, shares of Company stock purchased on the open market.
 NO HEDGING, PLEDGING, OR SHORT SELLING
 The Company maintains a trading policy that prohibits any hedging, pledging, or short selling (profiting if the market price decreases) of Company securities by any director or employee (including executive officers) whose function and responsibilities provide access to material, non-public information about the Company. The trading policy also prohibits such persons from pledging Company securities as collateral in a margin account with a broker-dealer.
 CLAWBACK POLICY
 We maintain a Compensation Recoupment (Clawback) Policy, which is intended to comply with the requirements of Nasdaq Listing Standard 5608 implementing Rule 10D-1 under the Exchange Act. In the event the Company is required to prepare an accounting restatement of the Company's financial statements due to material non-compliance with any financial reporting requirement under the federal securities laws, the Company will recover, on a reasonably prompt basis, the excess incentive-based compensation received by any covered executive, including the NEOs, during the prior three fiscal years that exceeds the amount that the executive otherwise would have received had the incentive-based compensation been determined based on the restated financial statements.

 ADDITIONAL NARRATIVE DISCLOSURE
 OTHER COMPENSATION AND BENEFITS
 The NEOs are eligible to participate in employee benefit plans and programs, including medical plans, dental and vision coverage, short-term and long-term disability insurance, and term life insurance, to the same extent as the Company's other full-time employees, subject to the terms and eligibility requirements of those plans. The NEOs also are eligible to participate in the Company's 401(k) defined contribution plan, subject to limits imposed by the Internal Revenue Code, to the same extent as the Company's other full-time employees. We do not maintain any defined benefit pension plans or any nonqualified deferred compensation plans.
 We provide our NEOs with limited perquisites. In order to attain cost savings versus hotel stays, each of our NEOs, who have principal work locations other than the Company's headquarters, are provided with a corporate apartment near our headquarters. In addition, our NEOs are eligible for executive health benefits, which include an annual physical. The Company's CEO received a modest country club membership in Gaston County, North Carolina. The Company believes it is important for our executives to engage with and support business relationships and learn more about the community and business needs in Gaston County, which the country club memberships facilitate.
 EQUITY GRANT TIMING PRACTICES
 The Leadership and Compensation Committee and the Board generally approve annual equity awards, including to the NEOs, shortly after the filing of this Annual Report. During 2024, the Leadership and Compensation Committee and the Board did not take material nonpublic information into account when determining the timing and terms of any equity award, and the Company did not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation.

 POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL
 Employment Agreements
 We have entered into at-will employment agreements with each of our NEOs in connection with our Redomiciliation in 2021. Each of the employment agreements provides for the following severance and other benefits upon the NEO's termination by the Company without "cause" or resignation by the NEO for "good reason" (collectively, a "Covered Termination"), with certain enhanced severance benefits in the event such Covered Termination occurs within three months prior to or within 12 months following a change in control (a "CIC Covered Termination"). The potential Merger with Sayona Mining will constitute a change in control for purposes of the employment agreements.

 (1) Mr. Brindle retired from the Company effective December 31, 2024.
 Equity Awards
 The award agreements for the stock options, RSUs, and PRAs granted in 2023 and 2024 also provide for pro-rata vesting upon the NEO's death, disability or retirement, with any performance conditions deemed satisfied at target. For purposes of these awards, "retirement" is defined as (i) age 63 with six years of service if retirement occurs in 2023, (ii) age 61 with seven years of service if retirement occurs in 2024, and (iii) age 59 with eight years of service if retirement occurs in 2025. Mr. Phillips was retirement-eligible with respect to these awards as of December 31, 2024; however, no additional portion of the award would have vested upon a retirement on December 31, 2024. In addition, if an NEO was age 62 with five years of service as of the applicable grant date, then any termination (other than a termination for "cause") that occurs during 2025 will result in full acceleration. Based on each NEO's age and years of service as of the grant date, only Mr. Phillips is eligible for such full acceleration.

 DIRECTOR COMPENSATION
 The Board's policy is to compensate non-executive directors with the intent to attract directors with experience applicable to our operations and strategy by providing fair pay, aligning the interests of our non-executive directors with the long-term interests of our stockholders, and structuring a program that is simple, transparent and easy for stockholders to understand. The Leadership and Compensation Committee and the Board annually review non-executive director compensation to ensure such compensation remains current with market practices and the foregoing principles.

 The following table summarized the cash retainers for service as a member of the Board and as a member or chair of our Board committees, as well as an annual equity grant:

 In accordance with the 2024 director compensation program, each non-executive director received an annual equity award of RSUs, which were subject to stockholder approval at the 2024 annual meeting. The number of RSUs granted is calculated using the target value and the volume-weighted average price of the Company's common stock for the 20-day period ending on February 29, 2024, resulting in Mr. Armstrong receiving 13,976 RSUs and each other non-executive director receiving 7,724 RSUs. The RSU awards vested immediately upon receiving stockholder approval; however, non-executive directors are restricted from selling the shares received in settlement of the RSUs during the director's tenure as a Board member (other than such number as is necessary to cover income taxes arising from such RSUs). We also prohibit non-executive directors from entering into arrangements to limit their exposure to equity awards granted as part of their compensation package.

For additional information regarding the assumptions underlying this calculation, please see Note 4—Stock-Based Compensation to the audited consolidated financial statements included in this Annual Report.

 STOCK OWNERSHIP GUIDELINES
 We require our directors to own significant amounts of our stock. Each non-executive director is required to accumulate stock equal to 5x the cash component of a non-executive director's annual retainer (excluding any retainers for service on committees of the Board

 and any retainers for Board and committee leadership).Non-executive directors have five years to meet the requirement measured from April 28, 2022, the date the guidelines were adopted, or, if later, the time they are first retained as directors.
 Individual and joint holdings of the Company's stock with immediate family members count toward fulfilling the guidelines. Until a director holds the requisite number of shares of Company stock, the director may not sell more than 50% of the shares, net of shares sold for tax obligations, acquired from the vesting of stock awards. However, prior to meeting our stock ownership guidelines, a director is permitted to sell, without restriction, shares of Company stock purchased directly or indirectly by the director. All non-executive directors are either currently in compliance with the guidelines or expected to comply with the guidelines by the end of the five-year grace period.
 INDEMNIFICATION AGREEMENTS
 We have entered into indemnification agreements with our directors and our executive officers. The indemnification agreements and our Bylaws require us to indemnify these individuals to the fullest extent permitted by Delaware law.

 Item 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE.

 RELATED PERSON TRANSACTIONS POLICY
 We have adopted a written Related Person Transactions policy that sets forth our procedures for the identification, review, consideration and approval or ratification of interested transactions. For purposes of our policy, an interested transaction is any transaction, arrangement or relationship or series of similar transactions, arrangements or relationships (including any indebtedness or guarantee of indebtedness) in which (i) the aggregate amount involved exceeds or is expected to exceed the lesser of $120,000 or one percent of the average of the Company's total assets at year-end for the last two completed fiscal years (including any periodic payments or installments due on or after the beginning of the Company's last completed fiscal year and, in the case of indebtedness, the largest amount expected to be outstanding and the amount of annual interest thereon), (ii) the Company or any of its subsidiaries is a participant and (iii) any related person has or will have a direct or indirect interest. A related person is any (i) person who is or was (since the beginning of the Company's last completed fiscal year, even if they do not presently serve in that role) an executive officer, director or nominee for election as a director, (ii) greater than 5% beneficial owner of the Company's common stock or (iii) immediate family member of any of the foregoing. Transactions involving compensation for services provided to us as an employee or director, among other limited exceptions, are deemed to have standing pre-approval by the Audit Committee but may be specifically reviewed if appropriate in light of the facts and circumstances.
 Under the policy, if a transaction has been identified as an interested transaction, our management must present information regarding the interested transaction to our Audit Committee for review, consideration, and approval or ratification. We will collect information that we deem reasonably necessary from each director, executive officer, and, to the extent feasible, significant stockholder to enable us to identify any existing or potential interested transaction and to effectuate the terms of the policy. In addition, under our Code of Business Conduct and Ethics, our directors, officers and employees have an affirmative responsibility to disclose any transaction or relationship that gives rise to an actual or potential conflict of interest. In considering interested transactions, our Audit Committee will take into account, among other factors it deems appropriate, whether the interested transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person's interest in the transaction.
 The foregoing policies and procedures were followed with respect to the transaction described below.

 RELATED PERSON TRANSACTIONS
 The following is a summary of each transaction or series of similar transactions since January 1, 2024, or any currently proposed transaction, to which we were or are a party in which: (i) the amount involved exceeds $120,000; and (ii) any related person (including our directors, executive officers, beneficial owners of more than 5% of our common stock, and any members of their immediate

 family) had or will have a direct or indirect material interest, other than compensation and other arrangements that are described under the section titled "Executive Compensation" or that were approved by our Compensation Committee.
 Beneficial ownership of securities is determined in accordance with the rules of the SEC.

 SALE OF SHARES OF ATLANTIC LITHIUM
 On January 18, 2024, we sold 24,479,868 shares of Atlantic Lithium for an average $ 0.32 per share. The shares sold represented approximately 4 % of Atlantic Lithium's outstanding shares and resulted in net proceeds of $ 7.7 million. In connection with the sale of the shares, we no longer hold a board seat with Atlantic Lithium and therefore do not exercise significant influence. Our remaining investment in Atlantic Lithium of approximately 5 % is accounted for as an investment in marketable securities and presented at fair value at each reporting date based on the closing price of Atlantic Lithium's share price on the ASX. Our reduced ownership in Atlantic Lithium has no impact on our earn-in or offtake rights with Atlantic Lithium and the Ewoyaa project.

 SALE OF SHARES OF SAYONA MINING
 On February 21, 2024, we sold 1,249,806,231 shares of Sayona Mining for an average of $ 0.03 per share. The shares sold represented our entire holding in Sayona Mining and approximately 12 % of Sayona Mining's outstanding shares and resulted in net proceeds of $ 41.4 million. The sale of these shares has no impact on our joint venture or offtake rights with Sayona Quebec.

 DIRECTOR INDEPENDENCE
 Nasdaq listing rules require a majority of a listed company's board of directors be comprised of independent directors who, in the opinion of the board of directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Subject to specified exceptions, each member of a listed company's audit, compensation, and nominating committees must be independent, and audit and compensation committee members must satisfy additional independence criteria under the Exchange Act.
 Our Board undertook a review of its composition and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including the beneficial ownership of our common stock by each director, our Board has determined that Messrs. Armstrong, Beristain, Bless and Demby and Mses. Alvord and Hickton qualify as "independent directors" as defined under the Nasdaq listing rules. Mr. Phillips is not deemed to be independent under Nasdaq listing rules by virtue of his employment with the Company. In making such determinations, our Board considered the relationships that each such non-employee director has with the Company and all other facts and circumstances our Board deemed relevant in determining independence.
 Our Board also determined that each of the directors currently serving on the Audit Committee and the Leadership and Compensation Committee satisfies the heightened independence standards applicable to directors serving on audit committees and compensation committees under Nasdaq listing rules and the rules and regulations established by the SEC.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 To the Board of Directors and Stockholders of Piedmont Lithium Inc.
 Opinion on the Financial Statements
 We have audited the accompanying consolidated balance sheet of Piedmont Lithium Inc. and its subsidiaries (the "Company") as of December 31, 2024, and the related consolidated statements of operations, of comprehensive loss, of changes in equity and of cash flows for the year then ended, including the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.
 Basis for Opinion
 These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audit. 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 audit of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.
 Our audit 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 audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.
 Critical Audit Matters
 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 (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters 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.
 Revenue Recognition
 As described in Notes 2 and 3 to the consolidated financial statements, the Company's consolidated revenue was $99.9 million for the year ended December 31, 2024. The Company recognizes revenue from product sales at a point in time when performance obligations are satisfied under the terms of contracts with their customers. A performance obligation is deemed to be satisfied when control of the product is transferred to the Company's customer, which is typically upon delivery to the shipping carrier. Revenue is measured as the amount of consideration expected to be received in exchange for transferring products to their customers.
 The principal considerations for our determination that performing procedures relating to revenue recognition is a critical audit matter are a high degree of auditor effort in performing procedures and evaluating audit evidence related to the Company's revenue recognition.
 Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included, among others (i) testing revenue recognized by obtaining and inspecting source documents, such as contracts, purchase orders, invoices, proof of shipment or delivery, and cash receipts; (ii)

 evaluating management's assessment of the terms and conditions of the contracts and the related impact on the revenue recognized; and (iii) confirming a sample of outstanding customer invoice balances as of December 31, 2024 and, for confirmations not returned, obtaining and inspecting source documents, such as contracts, invoices, proof of shipment or delivery, and subsequent cash receipts.

 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

 1. DESCRIPTION OF COMPANY
 Nature of Business
 Piedmont Lithium Inc. ("Piedmont Lithium," "we," "our," "us," or "Company") is a U.S. based, development-stage, multi-asset, integrated lithium business in support of a clean energy economy and U.S. and global energy security. We plan to supply lithium hydroxide to the electric vehicle and battery manufacturing supply chains in North America by processing spodumene concentrate produced from assets we own or in which we have an economic interest.
 Our portfolio of projects includes our wholly-owned Carolina Lithium project, a proposed fully integrated spodumene ore-to-lithium hydroxide project and a second lithium hydroxide manufacturing train in Gaston County, North Carolina. The balance of our project portfolio includes strategic investments in lithium assets in Quebec, Canada, including the operating NAL mine; in Ghana, West Africa with Atlantic Lithium, including Ewoyaa; and in Newfoundland, Canada with Vinland Lithium.
 We also had a proposed secondary merchant lithium hydroxide manufacturing plant as part of our Tennessee Lithium project. Planned capacity for the Tennessee plant was consolidated to Carolina Lithium in the third quarter of 2024 as part of a two-phased development plan at Carolina Lithium.
 Basis of Presentation
 Our consolidated financial statements and related notes have been prepared on the accrual basis of accounting in conformity with U.S. GAAP and in conformity with the rules and regulations of the SEC. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Our reporting currency is U.S. dollars, and we operate on a calendar fiscal year. These consolidated financial statements reflect all adjustments and reclassifications that, in the opinion of management, are considered necessary for a fair statement of the results of operations, financial position, and cash flows for the periods presented. Certain prior period amounts have been reclassified to be consistent with current period presentation.

 Use of Estimates
 The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, assumptions, and allocations that affect amounts reported in the consolidated financial statements and related notes. Significant items that are subject to such estimates and assumptions include, but are not limited to, long-lived assets, fair value of stock-based compensation awards and marketable securities, income tax uncertainties, valuation of deferred tax assets, contingent assets and liabilities, legal claims, asset impairments, provisional revenue adjustments, collectability of receivables, and environmental remediation. Actual results could differ due to the uncertainty inherent in the nature of these estimates.
 We base our estimates and assumptions on current facts, historical experience, and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources. Actual results may differ materially and adversely from our estimates. To the extent there are material differences between estimates and actual results, future results of operations will be affected.

 Risk and Uncertainties
 We are subject to a number of risks similar to those of other companies of similar size in our industry including, but not limited to, the success of our exploration and development activities, success of our equity method investments in international projects, permitting and construction delays, the need for additional capital or financing to fund operating losses and investments in our lithium projects and affiliates in Quebec and Ghana, lithium price risk, competition from substitute products and services, protection of proprietary technology, litigation, and dependence on key individuals.
 Since inception, we have devoted substantial effort and capital resources to our exploration and development activities, permitting activities, and construction activities, which includes such activities in international projects as part of our equity method investments. We have incurred net losses and negative cash flows from operations, including net losses of $ 64.8 million and $ 21.8 million in the years ended December 31, 2024 and 2023, respectively. We have accumulated deficits of $ 191.6 million and $ 126.8 million as of

 December 31, 2024 and 2023, respectively. The critical minerals value chain continues to experience headwinds, which have negatively impacted the prices of lithium we sell. As a development stage company, we expect to continue to recognize losses and generate negative cash flows from operations for the foreseeable future as we continue to fund our development and exploration activities.
 In light of current market conditions, we implemented our 2024 Cost Savings Plan to reduce our operating expenses, delay capital expenditures into 2025 and beyond, and limit investments in our lithium projects and affiliates. We had available cash on hand of $ 87.8 million as of December 31, 2024. During the third quarter of 2024, we entered into a working capital facility whereby we may borrow up to $ 25.0 million based on the value of committed volumes of spodumene concentrate shipments occurring within the following twelve months. The Credit Facility contains a subjective acceleration clause that allows the lender to change the payment terms of the arrangement if there is a material change in our credit worthiness including acceleration of repayment up to the full amount of any outstanding borrowings. We had an outstanding balance on the Credit Facility of $ 25.0 million as of December 31, 2024. See Note 14—Debt Obligations.
 Based on our operating plan, which includes our 2024 Cost Savings Plan and ongoing access to and utilization of the Credit Facility discussed above, we believe our cash on hand and the Credit Facility will be sufficient to fund our operations and meet our obligations as they come due for the twelve months following the date these consolidated financial statements are issued. However, we have based our estimate on assumptions that may prove to be wrong, and our operating plan may change as a result of many factors, including lithium pricing. As a result, we could deplete our capital resources sooner than we currently expect. No assurances can be given that any additional cost reduction strategies we undertake would be sufficient to meet our needs. We expect to finance our future cash needs through a combination of sales of non-core assets, equity offerings, debt financings, and strategic partnerships. If we are unable to obtain funding, we would be forced to delay, reduce, or eliminate some or all of our exploration and development activities and joint venture fundings, which could adversely affect our business prospects and ultimately our ability to operate.
 Our long-term success is dependent upon our ability to successfully raise additional capital or financing or enter into strategic partnership opportunities. Our long-term success is also dependent upon our ability to obtain certain permits and approvals, develop our planned portfolio of projects, earn revenues, and achieve profitability. No assurances can be given that we will be able to successfully achieve these dependencies.
 Proposed Merger with Sayona Mining
 On November 18, 2024, we entered into the Merger Agreement with Sayona Mining, whereby Piedmont and Sayona Mining will be combined on a stock-for-stock basis where each share of Piedmont common stock, par value US$0.0001 per share, issued and outstanding immediately prior to the consummation of the Merger, subject to certain exclusions, shall be converted into the right to receive from Sayona Mining 527 Sayona Mining ordinary shares.
 Consummation of the Merger, which is expected to occur in mid-2025, is subject to certain closing conditions, including requisite approvals of Piedmont's stockholders and Sayona Mining's shareholders of the Merger Agreement. The Merger Agreement contains certain termination rights in favor of Sayona Mining and Piedmont, including if the Merger is not consummated on or before September 30, 2025 or if the requisite approvals of Sayona Mining shareholders and Piedmont stockholders are not obtained.
 The foregoing summary of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the terms and conditions of the Merger Agreement, a copy of which is attached as Exhibit 2.1 to this Annual Report.

 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 Revenue Recognition
 We recognize revenue from product sales at a point in time when performance obligations are satisfied under the terms of contracts with our customers. A performance obligation is deemed to be satisfied when control of the product is transferred to our customer, which is typically upon delivery to the shipping carrier. Where a contract contains more than one distinct performance obligation, the transaction price is allocated to each performance obligation based on the standalone selling price of each performance obligation, although these situations do not occur frequently and are generally not built into our contracts. Revenue is measured as the amount of consideration expected to be received in exchange for transferring the products to our customers. Some contracts contain prepayment provisions which allow the customer to secure the right to receive their requested product volumes in a future period. Revenue from these contracts is initially deferred, thus creating a contract liability. Initial pricing is typically billed 5 days to 30 days after the departure of the shipment and is paid between 15 days to 75 days after the departure of the shipment. Final adjustments to prices may take longer to resolve. When the final price has not been resolved by the end of a reporting period, we estimate the expected sales

 price based on the initial price, market pricing, and known quality measurements. We warrant to our customers that our products conform to mutually agreed product specifications.
 We have elected to account for shipping and handling costs for spodumene concentrate contracts as fulfillment activities and not as promised goods or services; therefore, these activities are not considered separate performance obligations. We have elected the practical expedient relating to significant financing components and as such will not consider the possibility of a contract having a significant financing component (which would effectively attribute a portion of the sales price to interest income) unless, if at contract inception, the expected payment terms (from time of delivery or other relevant criterion) are more than one year.
 Our lithium products are sold to global and regional customers in the electric vehicle and electronics markets, among others. We currently work with end users in a number of markets to tailor our products to their specifications and will work with these end users as we add more products.
 Exploration Costs
 We incur costs in resource exploration, evaluation and development during the different phases of our resource development projects. Exploration costs incurred before the declaration of proven and probable resources, which primarily include exploration, drilling, engineering, metallurgical test-work, and compensation for employees associated with exploration activities, are expensed as incurred. After proven and probable resources are declared, exploration and mine development costs necessary to bring the property to commercial capacity or increase the capacity or useful life are capitalized.
 Foreign Currencies
 These consolidated financial statements have been presented in our reporting currency, U.S. dollars.
 Gains and losses arising from translations or settlements of foreign currency denominated transactions or balances are included in the determination of income. Foreign currency translation adjustments resulting from the change in functional currency are included in "Other comprehensive (loss) income, net of tax," and gains and losses resulting from foreign currency transactions are presented in "Other loss" in our consolidated financial statements.
 Earnings per Share
 We compute earnings per share in accordance with ASC Topic 260 – "Earnings per Share." Basic net income (loss) per common share is computed by dividing net loss by the weighted-average number of shares of common shares outstanding during the period. Diluted net income (loss) per share of common stock is computed by giving effect to all potential dilutive shares of common stock, including options, RSUs and PRAs. Basic and diluted net income (loss) per share of common stock were the same for all periods presented as the impact of all potentially dilutive securities outstanding was anti-dilutive.
 Stock-based Compensation
 We record stock-based compensation in accordance with ASC Topic 718 – "Stock Compensation." Equity-settled stock-based payments are provided to directors, officers, employees, consultants and other advisors. These stock-based payments are measured at the fair value of the equity instrument at the grant date in accordance with ASC Topic 718. Fair value is determined using the Black-Scholes valuation model as well as the Monte Carlo simulation. We have applied a graded (tranche-by-tranche) attribution method and we record stock-based compensation expense on an accelerated basis over the vesting period of the share award. Forfeitures are accounted for in the period incurred.
 Fair Value of Financial Instruments
 Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
 We follow ASC Topic 820 – "Fair Value Measurement," which establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows:
 Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets.

 Level 2: Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable for the asset or liability, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived from observable market data by correlation or other means.
 Level 3: Inputs for the asset or liability that are not based on observable market data (unobservable inputs).
 The level within which the financial asset or liability is classified is determined based on the lowest level of significant input to the fair value measurement.
 Income Taxes
 We account for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. In addition, deferred tax assets are also recorded with respect to net operating losses and other tax attribute carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. Valuation allowances are established when realization of the benefit of deferred tax assets is not deemed to be more likely than not. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
 We intend to continue maintaining a valuation allowance on our deferred tax assets if, in our judgement, it appears that it is more likely than not that all or some portion of the asset will not be realized. When assessing the need for a valuation allowance, we considered all available evidence, including all potential sources of taxable income, future reversals of taxable temporary differences, projections of taxable income, and income from tax planning strategies, as well as any other available and relevant information. Existing valuation allowances are re-examined each period. If it were determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, would be released in the period this determination is made.
 We only recognize a tax benefit after concluding that it is more likely than not that the benefit will be sustained upon audit by the respective taxing authority based solely on the technical merits of the associated tax position. Once the recognition threshold is met, we recognize a tax benefit measured as the largest amount of the tax benefit that, in our judgment, is greater than 50% likely to be realized. Interest and penalties related to income tax liabilities are included in "Income tax expense" in our consolidated statements of operations.
 Equity Method Investments
 We apply the equity method of accounting for investments when we have significant influence, but not controlling interest in the investee. Judgment regarding the level of influence over each equity method investment includes key factors such as ownership interest, representation on the board of directors, participation in policy-making decisions, operational decision-making authority, and material intercompany transactions. In applying the equity method, we record the investment at cost and subsequently increase or decrease the carrying amount of the investment by our proportionate share of the net earnings or losses and other comprehensive income of the investee, adjusted for differences between their local GAAP and U.S. GAAP. Our investment balance is also adjusted for currency translation adjustments representing fluctuations between the functional currency of the investees. The carrying value of our equity method investments is reported as "Equity method investments," adjustments related to foreign currency adjustments and our proportional shares of other comprehensive (loss) income is reported in "Accumulated other comprehensive loss" in our consolidated balance sheets. For all equity method investments, we record our share of an investee's income or loss on a one-quarter lag. We evaluate material events occurring during the one-quarter lag to determine whether the effects of such events should be disclosed in our consolidated financial statements. We classify distributions received from equity method investments using the cumulative earnings approach in our consolidated statements of cash flows. A change in our proportionate share of an investee's equity resulting from issuance of common shares or in-substance common shares by the investee to third parties is recorded as a gain or loss in our consolidated statements of operations in accordance with ASC Topic 323 – "Investments-Equity Method and Joint Ventures," (Subtopic 10-40-1). We assess investments for impairment whenever events or changes in circumstances indicate that the carrying value of an investment may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, then we record a loss as a component of our share of earnings or losses of the equity method investee in the current period. We recorded a loss of $ 2.2 million for impairment charges in the year ended December 31, 2023. No impairment losses were recorded on equity method investments for any other period presented. See Note 11—Equity Method Investments for further information on our equity method investments.

 Leases
 We account for leases in accordance with ASC Topic 842 – "Leases," which requires lessees to recognize lease liabilities and ROU assets on the balance sheet for contracts that provide lessees with the right to control the use of identified assets. As part of this adoption, we made certain accounting policy elections which are detailed in the recently adopted accounting pronouncements sub-section in Note 15—Leases, to the consolidated financial statements in this Annual Report. We evaluate whether our contractual arrangements contain leases at the inception of such arrangements. Specifically, management considers whether we control the underlying asset and have the right to obtain substantially all of the economic benefits or outputs from the asset.
 ROU lease assets represent our right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments. Both the ROU lease asset and liability are recognized as of the lease commencement date based on the present value of the lease payments over the lease term. Our leases do not provide an implicit borrowing rate that can readily be determined. Therefore, we apply a discount rate based on the incremental borrowing rate, which is determined using our synthetic credit rating and other information available as of the lease commencement date. ROU lease assets also include any lease payments made before their contractual due dates and exclude any lease incentives.
 Our lease agreements may include options to extend the lease term or to terminate the lease early. We include options to extend or terminate leases upon determination of the ROU lease asset and liability when we are reasonably certain we will exercise these options. Operating lease expense attributable to lease payments is recognized on a straight-line basis over the lease term and is included in "Selling, general and administrative expenses" in our consolidated statements of operations.
 We evaluate ROU assets for impairment consistent under our impairment of long-lived assets policy. We had no sales-type or finance leases as of December 31, 2024 and 2023.
 Cash and Cash Equivalents
 We consider all highly liquid instruments with a maturity of three months or less at the time of issuance to be cash equivalents. We maintain cash deposits with high credit quality financial institutions. The deposits with these financial institutions may exceed the federally insured limits; however, these deposits typically are redeemable upon demand. We have not experienced any losses because of these deposits and do not expect to incur any losses in the future.
 Long-Lived Assets
 Mining Interests
 Mining interests are recorded at cost and include land acquisition payments and land option payments to landowners, which include legal fees and other direct costs to enter into these contract agreements. We own land, specifically surface properties and the associated mineral rights, as part of Carolina Lithium in the U.S., specifically in North Carolina. We have entered into exclusive option agreements or land acquisition agreements, which upon exercise, allow us to purchase, or in some cases lease, surface properties and the associated mineral rights in North Carolina from landowners. For those properties under option, no liability is recorded until we are certain of exercising the option. Mining interests in the exploration and development stage are not amortized until the underlying property is converted to the production stage, at which point the mining interests are depleted over the estimated recoverable proven and probable reserves.
 Development stage mining interests represent interests in properties under development that contain proven and probable reserves. Exploration stage mining interests represent interests in properties that are believed to potentially contain mineralized material consisting of: (i) mineralized material within pits; mineralized material with insufficient drill spacing to qualify as proven and probable reserves as well as and mineralized material in close proximity to proven and probable reserves; (ii) around-mine exploration potential not immediately adjacent to existing reserves and mineralization, but located within the immediate mine area; (iii) other mine-related exploration potential that is not part of current mineralized material and is comprised mainly of material outside of the immediate mine area; (iv) greenfield exploration potential that is not associated with any other production, development or exploration stage property, as described above; or (v) any acquired right to explore or extract a potential mineral deposit. Our mineral rights generally are enforceable regardless of whether proven and probable reserves have been established.
 Mine Development
 Mine development assets include engineering and metallurgical test-work, drilling and other related costs to delineate an ore body, and the removal of overburden to initially expose an ore body at open pit surface mines. Costs incurred before mineral resources are

 classified as proven and probable reserves are expensed and recorded to "Exploration costs" in our consolidated statements of operations. Capitalization of mine development project costs begins once mineral resources are classified as proven and probable reserves. Drilling and related costs are capitalized for an ore body where proven and probable reserves exist and the activities are directed at obtaining additional information on the ore body or converting mineralized material to proven and probable reserves. All other drilling and related costs are expensed as incurred. The cost of removing overburden and waste materials to access the ore body at an open pit mine prior to the production phase are referred to as pre-stripping costs. Pre-stripping costs will be capitalized during the development of an open pit mine. The removal, production, and sale of de minimis salable materials may occur during the development phase of an open pit mine and are assigned incremental mining costs related to the removal of that material. Mine development assets will be depleted using the units-of-production method based on estimated recoverable metric tons in proven and probable reserves. To the extent that these costs benefit an entire ore body, they will be depleted over the estimated life of the ore body. As of December 31, 2024, we had no wholly owned projects in the production phase, and we did not record depletion expense for any of our mine development assets.
 Property, Plant and Equipment
 Property, plant and equipment is recorded at cost, net of accumulated depreciation and depletion. Depreciation is computed on a straight-line basis over the estimated useful lives.
 Impairment of Long-Lived Assets
 Assets that are subject to depreciation, depletion, or amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable, or for non-depreciable assets in accordance with ASC Topic 360 – "Property, Plant, and Equipment." Circumstances which could trigger a review include, but are not limited to: significant decreases in the market price of the asset; significant adverse changes in the business climate or legal factors; accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of the asset; current period cash flow or operating loss combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and current expectation that the asset will more likely than not be sold or disposed before the end of its estimated useful life.
 Recoverability of assets is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by an asset. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment charge is recognized at the amount by which the carrying amount exceeds the estimated fair value of the asset. The estimated fair value is determined using a discounted cash flow analysis. Any impairment in value is recognized as an expense in the period when the impairment occurs. We recognized $ 4.1 million in impairment charges associated with long-lived assets for the year ended December 31, 2024. We had no impairment charges for the year ended December 31, 2023.
 Asset Retirement Obligations
 We follow the provisions of ASC Topic 410 – "Asset Retirement and Environmental Obligations, " which establishes standards for the initial measurement and subsequent accounting for obligations associated with the sale, abandonment, or other disposal of long-lived tangible assets arising from the acquisition, construction, or development and for normal operations of such assets. We record the fair value of a liability for an asset retirement obligation as an asset and liability when there is a legal obligation associated with the retirement of a tangible long-lived asset and the liability can be reasonably estimated. The legal obligation to perform the asset retirement activity is unconditional, even though uncertainty may exist about the timing and/or method of settlement that may be beyond the entity's control. See Note 19—Commitments and Contingencies.
 Restructuring and Impairment
 We accrue for severance and other employee separation costs under these actions when it is probable that benefits will be paid and the amount is reasonably estimable. The rates used in determining severance accruals are based on existing plans, historical experiences, and negotiated settlements. If the amounts and timing of cash flows from restructuring activities are significantly different from what we have estimated, the actual amount of restructuring and other related charges could be materially different, either higher or lower, than those we have recorded. Costs directly related to the restructuring effort, such as legal fees, and care and maintenance of facilities we are exiting are expensed in the period incurred. For a full description of our restructuring actions, see Note 6—Restructuring and Impairment.

 Recently Issued Accounting Standards Not Yet Adopted
 In November 2024, the FASB issued guidance, Disaggregation of Income Statement Expenses, which requires the disaggregation of certain expenses in the notes to the consolidated financial statements, to provide enhanced transparency into the expense captions presented on the face of the income statement. As amended in January 2025, this guidance will be effective for annual reporting periods beginning with the fiscal year beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this guidance may be applied either prospectively or retrospectively. With the exception of expanding disclosures to include more granular income statement expense categories, we do not expect the adoption of this guidance to have a material effect on our consolidated financial statements taken as a whole.
 In December 2023, the FASB issued guidance, Improvements to Income Tax Disclosures, which requires enhanced income tax disclosures, including disaggregation of information in the rate reconciliation table and disaggregated information related to income taxes paid. The amendments in guidance are effective for the fiscal year ending December 31, 2025. We are currently evaluating the impact that this update will have on the disclosures in our consolidated financial statements.
 Recently Issued and Adopted Accounting Pronouncements
 In November 2023, the FASB issued guidance, Improvements to Reportable Segment Disclosures, requiring public entities to disclose information about their reportable segments' significant expenses and other segment items on an interim and annual basis. Public entities with a single reportable segment are required to apply the disclosure requirements in the guidance, as well as all existing segment disclosures and reconciliation requirements on an interim and annual basis. We adopted the guidance during the year ended December 31, 2024. See Note 17—Segment Reporting in the accompanying notes to our consolidated financial statements for further details.
 We have considered the applicability and impact of all other recently issued accounting pronouncements and have determined that they were either not applicable or were not expected to have a material impact on our consolidated financial statements.

 3. REVENUE
 Our sales based on a provisional price contain an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of the concentrates at the forward price at the time of sale. The embedded derivative, which is not designated for hedge accounting, is recorded at fair value with any changes recognized as revenue each period prior to final settlement. We warrant to our customers that our products conform to mutually agreed product specifications.
 100 % of revenue was related to four customers for the year ended December 31, 2024 and three customers for the year ended December 31, 2023. All sales related to these customers originated in North America. We evaluate the collectability of our accounts receivable on an individual customer basis. Our reserve for credit losses was nil as of December 31, 2024.
 We may be subject to provisional revenue adjustments associated with commodity price fluctuations for our spodumene concentrate sales. In some cases, these adjustments are unknown until final settlement. As of December 31, 2024, approximately 24,350 dmt with an average provisional price of $ 745 per dmt were subject to final pricing over the next several months.
 Revenue and provisional adjustments are reflected in the following table:

 4. STOCK-BASED COMPENSATION
 Stock Incentive Plan
 Under our Stock Incentive Plan, we are authorized to grant 3,000,000 shares, or share equivalents, of stock options, stock appreciation rights, restricted stock units, and restricted stock, any of which may be performance based. Our Leadership and Compensation Committee determines the exercise price for stock options and the base price of stock appreciation rights, which may not be less than the fair market value of our common stock on the date of grant. Generally, stock options and stock appreciation rights fully vest after three years of service and expire at the end of ten years from the date of grant. PRAs vest upon achievement of certain pre-established performance targets that are based on specified performance criteria over a performance period. As of December 31, 2024, 1,412,628 shares of common stock were available for issuance under our Stock Incentive Plan.
 We include the expense related to stock-based compensation in the same financial statement line item as cash compensation paid to the same employee. As of December 31, 2024, we had remaining unvested stock-based compensation expense of $ 4.9 million to be recognized through December 31, 2026. Additionally, and if applicable, we capitalize personnel expenses, including stock-based compensation expenses, attributable to the development of our mine and construction of our plants. We recognize share-based award forfeitures as they occur.
 The components and presentation of stock-based compensation are presented in the following table:

 (2)These costs relate to direct labor costs associated with our lithium projects and are included in "Property, plant and mine development, net" in our consolidated balance sheets.
 Stock Option Awards
 Stock options may be granted to employees, officers, non-employee directors, and other service providers. For stock option awards, the fair value is estimated at the date of grant using the Black-Scholes valuation model, and the expense is recognized over the option vesting period.
 The following assumptions were used to estimate the fair value of stock options granted during the periods presented below:

 Restricted Stock Unit Awards
 RSUs may be granted to employees and non-employee directors and recognized as stock-based compensation expense over the vesting period, subject to the passage of time and continued service during the vesting period, based on the market price of our common stock on the grant date. In some instances, awards may vest concurrently with or following an employee's termination.
 Performance Rights Awards
 As of December 31, 2024, there were 3,622 vested and unissued Milestone PRAs and 280,256 unvested TSR PRAs. The awards become eligible to vest only if certain goals are achieved and will vest only if the grantee remains employed by the Company through each applicable vesting date, subject to certain accelerated vesting terms for qualified terminations. Each performance right converts into one share of common stock upon vesting of the performance right.
 We determined the fair value of Milestone PRAs based upon the market price of our common stock on the grant date. Milestone PRAs are subject to certain milestones related to construction, feasibility studies, and offtake agreements, which must be satisfied in order for PRAs to vest.
 We estimated the fair value of the TSR PRAs at the grant date using a Monte Carlo simulation. The Monte Carlo simulation fair value model requires the use of highly subjective and complex assumptions, including price volatility of the underlying stock to simulate a range of possible future stock prices for the Company and each member of the peer group over the performance periods to determine the grant date fair value. Compensation expense is recognized based upon the assumption of 100 % achievement of the TSR goal and is reflected over the service period of the award. Compensation expense will not be reversed even if the threshold level of TSR is never achieved. The number of shares that may vest ranges from 0 % to 200 % of the target amount and is based on actual performance at the end of each performance period ranging from 1 year to 3 years.
 The following assumptions were used in the Monte Carlo simulation for TSR PRAs granted during periods presented below:

 2024

 6. RESTRUCTURING AND IMPAIRMENT
 During the first quarter of 2024, our Board approved the 2024 Cost Savings Plan in response to the lithium market downturn. As part of our 2024 Cost Savings Plan, we reduced operating costs, mainly within corporate overhead, deferred capital spending to 2025 and beyond, and limited cash investments in and advances to affiliates. We reduced our workforce by 28 % in the first quarter of 2024 and lowered third-party spending consisting primarily of professional fees and other operating costs. As a result of our initial reduction in workforce, we recorded $ 1.8 million in severance and employee benefits costs in the three months ended March 31, 2024.
 In August 2024, we announced plans to streamline our U.S. lithium hydroxide production plans in favor of shifting our proposed Tennessee Lithium conversion capacity to Carolina Lithium in a phased approach, thereby allowing us to deploy capital and technical resources more efficiently. During the year ended December 31, 2024, and in connection with this shift, we recorded restructuring and impairment charges associated with Tennessee Lithium totaling $ 0.3 million to continue operating the monofill operations which we plan to sell or decommission in the near future.
 Due to the prolonged lithium market downturn, we expanded our 2024 Cost Savings Plan and further reduced our workforce, including operational and corporate staff, by 32 % in October 2024. We recorded charges in the fourth quarter of 2024 associated with this further reduction in workforce of approximately $ 2.8 million, which consisted of $ 1.2 million in cash severance and employee benefits and $ 1.6 million in non-cash stock compensation expense. As part of our 2024 Cost Savings Plan, we reduced our total workforce by 62 % in the year ended December 31, 2024.

 The following table presents the components of restructuring and impairment charges associated with our 2024 Cost Savings Plan for the year ended December 31, 2024. There were no restructuring and impairment charges during the year ended December 31, 2023.

 The gain on equity securities relates to realized and unrealized gains (losses) of our investments in marketable and equity securities. Loss on sale of assets primarily relates to our sale or disposal of property, plant and mine development assets. Other loss includes foreign currency exchange loss primarily related to our foreign bank accounts denominated in Canadian dollars and Australian dollars and marketable securities denominated in Australian dollars.

 8. EARNINGS PER SHARE
 We compute basic and diluted earnings per common share by dividing net earnings by the respective weighted-average number of common shares outstanding for the periods presented. Our calculation of diluted earnings per common share also includes the dilutive effects for the assumed vesting of outstanding options, RSUs, and PRAs based on the treasury stock method. In computing diluted earnings per share, the average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options. Diluted earnings per share excludes all potentially dilutive shares if their effect is anti-dilutive.
 Basic and diluted net loss per share is reflected in the following table:

 During the year ended December 31, 2024, we increased our reserve for uncertain income tax positions by $ 0.2 million related to research and development tax credits. As of December 31, 2024, we did not record accrued interest or penalties, nor did we record unrecognized net tax benefits that, if recognized, would affect our effective tax rate in any future period. We do not expect our unrecognized tax benefits will significantly change within the next twelve months. Interest and penalties related to income tax matters are classified as a component of income tax expense.

Our tax filings remain subject to audits by applicable tax authorities for a certain length of time following the tax year to which those filings relate. Tax years 2017 and forward generally remain open for examination for federal and state tax purposes. Tax years 2009 and forward generally remain open for examination for foreign tax purposes.

 (1)As of March 31, 2024, Sayona Mining was no longer accounted for as an equity method investment. During the three months ended March 31, 2024, we sold 1,249,806,231 shares of Sayona Mining for an average of $ 0.03 per share. The shares sold represented our entire holding in Sayona Mining, which was approximately 12 % of Sayona Mining's outstanding shares, and resulted in net proceeds of $ 41.4 million. The sale of these shares has no impact on our joint venture or offtake rights with Sayona Quebec.
 (2)As of March 31, 2024, Atlantic Lithium was no longer accounted for as an equity method investment. During the three months ended March 31, 2024, we sold 24,479,868 shares of Atlantic Lithium for an average $ 0.32 per share. The shares sold represented approximately 4 % of Atlantic Lithium's outstanding shares and resulted in net proceeds of $ 7.7 million. In connection with the sale of the shares, we no longer hold a board seat with Atlantic Lithium and therefore do not exercise significant influence. Our remaining investment in Atlantic Lithium represents approximately 5 % of Atlantic Lithium's outstanding shares as of December 31, 2024, and is accounted for as an investment in marketable securities and presented at fair value at each reporting date based on the closing price of Atlantic Lithium's share price on the ASX. See Note 13—Other Assets and Liabilities. Our reduced ownership in Atlantic Lithium has no impact on our earn-in or offtake rights with Atlantic Lithium and the Ewoyaa project.
 (3)Initial investment includes transaction costs of $ 0.3 million for the year ended December 31, 2023.
 (4)Gain on dilution of equity method investments relates to issuances of additional shares of Sayona Mining and Atlantic Lithium, which reduced our ownership interest in both Sayona Mining and Atlantic Lithium.
 (5)Impairment of equity method investment represents the difference between the carrying value, which includes $ 46.3 million in accumulated gains on dilution, and fair value of Sayona Mining as of December 31, 2023, and is included (loss) income from equity method investments in our consolidated statements of operations.
 (6)Gain on dilution of equity method investments relates to the exercise of stock options and share grants, which resulted in a reduction of our ownership in Atlantic Lithium, and is included in "Gain (loss) on sale of equity method investments" in our consolidated statements of operations.
 (7)Amounts reclassified from accumulated other comprehensive loss to net loss related to the sale of shares of equity method investments were $ 3.0 million and $ 0.6 million, net of tax, for Sayona Mining and Atlantic Lithium, respectively.

 We own an equity interest of 25 % in Sayona Quebec for the purpose of furthering our investment and strategic partnership in Quebec, Canada. The remaining 75 % equity interest is held by Sayona Mining. Sayona Quebec holds a 100 % interest in NAL, which consists of a surface mine and a concentrator plant, as well as Authier and Tansim.
 We hold a life-of-mine offtake agreement with Sayona Quebec for the greater of 113,000 dmt or 50 % of spodumene concentrate production per year. Our purchases of spodumene concentrate from Sayona Quebec are subject to market pricing with a price floor of

 $ 500 per dmt and a price ceiling of $ 900 per dmt for a grade of 6.0 % spodumene concentrate.
 In addition to lithium mining and concentrate production, NAL owns a partially completed lithium carbonate plant, which was developed by a prior operator of NAL. Sayona Quebec completed a preliminary technical study for the completion and restart of the NAL carbonate plant during the year ended December 31, 2023. If we decide to construct and operate a lithium conversion plant with Sayona Mining through our joint venture, Sayona Quebec, then spodumene concentrate produced from NAL would be preferentially delivered to that conversion plant upon commencement of conversion operations. Any remaining spodumene concentrate not delivered to the conversion plant would first be sold to us up to our offtake right and then to third-parties. Any decision to construct jointly-owned lithium conversion capacity must be agreed upon by both parties.
 In the year ended December 31, 2024, NAL produced approximately 193,162 dmt of spodumene concentrate and shipped approximately 200,800 dmt, of which approximately 116,700 dmt were sold to Piedmont Lithium. We sold approximately 116,700 dmt of spodumene concentrate and recognized $ 99.9 million in revenue with a realized sales price of $ 856 per dmt and a realized costs of sales of $ 763 per dmt.
 In the year ended December 31, 2023, NAL produced approximately 98,800 dmt of spodumene concentrate and shipped approximately 72,100 dmt, of which approximately 43,200 dmt were sold to Piedmont Lithium. We sold approximately 43,200 dmt of spodumene concentrate and recognized $ 39.8 million in revenue with a realized sales price of $ 920 per dmt and a realized costs of sales of $ 789 per dmt.
 Realized costs of sales is the average costs of sales based on our offtake pricing agreement with Sayona Quebec for the purchase of spodumene concentrate at a market price subject to a floor of $ 500 per dmt and a ceiling of $ 900 per dmt, with adjustments for product grade, and freight.
 We had payables to NAL totaling $ 6.7 million and $ 0.2 million as of December 31, 2024 and 2023, respectively. Payables to NAL are reported as "Payables to affiliates" in our consolidated balance sheets.

 Vinland Lithium
 We own an equity interest of approximately 20 % in Vinland Lithium, a Canadian-based entity jointly owned with Sokoman Minerals and Benton Resources. Vinland Lithium owns Killick Lithium, a large exploration property prospective for lithium located in southern Newfoundland, Canada. We have entered into an earn-in agreement with Vinland Lithium to acquire up to a 62.5 % equity interest in Killick Lithium through current and future phased investments.

 Advances to affiliates relate to staged investments for future planned lithium projects. We have a strategic partnership with Atlantic Lithium that includes Atlantic Lithium Ghana's flagship Ewoyaa project. Under our partnership, we entered into a project agreement to acquire a 50 % equity interest in Atlantic Lithium Ghana in two phases, with each phase requiring us to make future staged investments in Ewoyaa over a period of time in order to earn our additional equity interest. We have an earn-in agreement with Vinland Lithium to acquire up to a 62.5 % equity interest in Killick Lithium.
 Our maximum exposure to a loss as a result of our involvement in Ewoyaa and Killick Lithium is limited to the total amount funded by Piedmont Lithium to Atlantic Lithium and Vinland Lithium, respectively. As of December 31, 2024, we did no t own an equity interest in Atlantic Lithium Ghana or Killick Lithium. We have made advances to Atlantic Lithium for Ewoyaa totaling $ 10.6 million and $ 9.4 million in the years ended December 31, 2024 and 2023, respectively. We have made advances to Vinland Lithium for Killick Lithium totaling $ 0.8 million and $ 1.8 million in the years ended December 31, 2024, and 2023 respectively.

 Ewoyaa
 We completed Phase 1 of our investment in mid-2023, which allows us to acquire a 22.5 % equity interest in Atlantic Lithium Ghana, by funding Ewoyaa's exploration activities and DFS costs and notifying Atlantic Lithium of our intention to proceed with additional funding contemplated under Phase 2, which mainly consists of construction and development activities for Ewoyaa. Atlantic Lithium issued their DFS for Ewoyaa in June 2023. In August 2023, we supplied Atlantic Lithium with notification of our intent to proceed with additional funding for Phase 2. Our future equity interest ownership under Phase 1 remains subject to government approvals. Phase 2 allows us to acquire an additional 27.5 % equity interest in Atlantic Lithium Ghana upon completion of funding $ 70 million for capital costs associated with the development of Ewoyaa. Upon issuance of our equity interest associated with Phase 1 and completion and issuance of our equity interested associated with Phase 2, we expect to have a total equity interest of 50 % in Atlantic Lithium Ghana. Atlantic Lithium Ghana, in turn, will hold an 81 % interest in the Ewoyaa project net of the interests that will be held by the Ghanaian government and MIIF, resulting in an effective ownership interest of 40.5 % in Ewoyaa, by Piedmont Lithium.

 In October 2023, we entered into an earn-in agreement with Vinland Lithium to acquire up to a 62.5 % equity interest in Killick Lithium through current and future phased investments. As part of our investment, we entered into a marketing agreement with Killick Lithium for 100 % marketing rights and right of first refusal to purchase 100 % of all lithium products produced by Killick Lithium on a life-of-mine basis at competitive commercial pricing.

 Asset Retirement Obligations
 We follow the provisions of ASC Topic 410 – "Asset Retirement and Environmental Obligations," which establishes standards for the initial measurement and subsequent accounting for obligations associated with the sale, abandonment or other disposal of long-lived tangible assets arising from the acquisition, construction or development and for normal operations of such assets. We record the fair value of a liability for an asset retirement obligation as an asset and liability when there is a legal obligation associated with the retirement of a tangible long-lived asset and the liability can be reasonably estimated. The legal obligation to perform the asset retirement activity is unconditional, even though uncertainty may exist about the timing and/or method of settlement that may be beyond the entity's control.
 During the year ended December 31, 2023, we recognized an asset retirement obligation of $ 0.4 million related to the acquisition of a monofill disposal facility in Etowah, Tennessee, for Tennessee Lithium. In determining the asset retirement obligation, we calculated the present value of the estimated future cash flows required to reclaim the disturbed areas and perform any required monitoring. The Tennessee Department of Environment and Conservation requires that closure and post-closure obligations of the disposal facility be

 covered by a surety bond. Surety bonds securing closure and post-closure obligations at December 31, 2024 and 2023 totaled $ 3.3 million and $ 3.2 million, respectively.

 Credit Facility
 On September 11, 2024, we entered into a working capital facility, whereby we may borrow up to $ 25.0 million based on the value of committed volumes of spodumene concentrate occurring within the following twelve months. The outstanding balance under the facility is settled each time a vessel completes loading with volumes that have been committed under the terms of the facility. Interest is payable quarterly at the rate of SOFR plus 2.4 %. The lender has the right to modify the payment terms of the Credit Facility in the event we experience a material change in creditworthiness. The Credit Facility expires on September 11, 2027 but may be extended through December 31, 2028.
 We may borrow up to 40 % of the value of committed volumes of spodumene concentrate unless we elect to enter into a fixed-price arrangement with the lender that would allow us to increase borrowing up to 75 % of the value of future, committed volumes of spodumene concentrate through December 31, 2027. We determined the fixed-price arrangement to be an embedded derivative that must be bifurcated from the Credit Facility. The fair value of the embedded derivative was immaterial as of December 31, 2024. We re-evaluate the fair value of the fixed-price arrangement at the end of each reporting period.

 Mining Interests Financed by Sellers
 We have entered into long-term debt agreements to purchase surface properties and the associated mineral rights from landowners that form part of mining interests reported within "Property, plant and mine development, net" in our consolidated balance sheets. These purchases were fully or partly financed by the seller of each of the surface properties. Payment terms range from 2 years to 5 years, at interest rates ranging from 9.5 % to 13.0 %, with the majority of payments due in monthly installments ranging from approximately $ 4,000 to approximately $ 30,000. Long-term debt agreements are secured by the respective real property.

 Insurance Premium Financing Loan
 On May 23, 2024, we entered into a financing agreement through our insurance broker to spread the payment of our annual directors and officers insurance premium over a nine-month period. Insurance premiums financed totaled $ 2.1 million and were payable between May 2024 and January 2025 at an interest rate of 8.2 %.

 We are authorized to issue up to 100,000,000 shares of common stock, par value $ 0.0001 per share, and 10,000,000 shares of preferred stock, par value $ 0.0001 per share. We have no outstanding shares of preferred stock. Holders of our common stock are entitled to receive dividends when and if declared by the Board and are entitled to one vote per share on all matters submitted to a vote of the Stockholders.
 As of December 31, 2024, $ 500 million of securities were available under our shelf registration statement, which expires on September 26, 2027.
 Equity Transactions During the Year Ended December 31, 2024
 In November 2024, we issued a private placement of 238,095,300 CDIs at a price of $ 0.17 AUD per CDI, which represents a beneficial interest in one-hundredth of a share of our common stock. Share issuance costs associated with this share placement totaled $ 1.4 million and were accounted for as a reduction in the proceeds for share issuances in the consolidated balance sheets.
 In May 2024, we entered into an ATM Program with B. Riley Securities, Inc., whereby we may from time to time and, at our discretion, issue and sell up to $ 50 million of our common stock through any method deemed to be an at-the-market offering, as defined in Rule 415 of the Exchange Act, or any method specified in the ATM Program.
 We have not issued any shares under the ATM Program as of December 31, 2024 and through the filing of this Annual Report.
 In February 2024, we issued 52,701 shares of our common stock at an issue price of $ 14.17 per share as an advance of our funding obligations to Killick Lithium. There were no share issuance costs associated with the issuance and the value of the shares were treated as an advance within our earn-in agreement with Vinland Lithium to acquire up to a 62.5 % equity interest in Killick Lithium through staged investments.

 Equity Transactions During the Year Ended December 31, 2023
 In November 2023, we issued 62,638 shares with an issue price of $ 29.32 per share as an advance of our funding obligations to the Killick Lithium project. There were no share issuance costs associated with the issuance and the value of the shares were treated as an advance within our earn-in agreement with Vinland Lithium to acquire up to a 62.5 % equity interest in Killick Lithium through staged-investments.
 In February 2023, we received $ 75 million from LG Chem in exchange for 1,096,535 shares of our common stock at a price of $ 68.40 per share and in conjunction with a multi-year spodumene concentrate offtake agreement. Share issuance costs associated with the issuance totaled $ 3.9 million and were accounted for as a reduction in the proceeds from share issuances in our consolidated balance sheets.

 17. SEGMENT REPORTING
 We report our segment information in the same way management internally organizes the business in assessing performance and making decisions regarding allocation of resources in accordance with ASC Topic 280 – "Segment Reporting." We have a single reportable operating segment that operates as a single business platform. In reaching this conclusion, management considered the definition of the CODM, how the business is defined by the CODM, the nature of the information provided to the CODM, how the CODM uses such information to make operating decisions, and how resources and performance are assessed. The results of operations provided to and analyzed by the CODM are at the consolidated level, and accordingly, key resource decisions and assessment of performance are performed at the consolidated level. We have a single, common management team and our cash flows are reported and reviewed at the consolidated level only with no distinct cash flows at an individual business level. Our CODM is our CEO.
 Our lithium products are sold to global and regional customers in the electric vehicle and electronics markets, among others. We currently work with end users in a number of markets to tailor our products to their specifications and will work with these end users as we add more products.
 The CODM is provided with revenue, restructuring and impairment charges, interest expense, gain (loss) of equity method investments and total assets, which are consistent with those presented in the consolidated financial statements, as part of the measure of profit and loss reviewed.
 The CODM reviews both net income or (loss) and adjusted net income or (loss) when evaluating the performance of the reportable operating segment. We believe that adjusted measures provide meaningful information to assist management, investors, and analysts in understanding our financial condition and the results of operations. We believe this adjusted financial measure is important indicators of our recurring operations because it exclude items that may not be indicative of, or are unrelated to, our core operating results, and provides a better baseline for analyzing trends in our underlying business.
 Adjusted net loss is defined as net (loss) or income, as calculated under GAAP, plus or minus the gain or loss from sale of equity method investments, gain or loss on sale of assets, gain or loss from equity securities, gain or loss from foreign currency exchange, restructuring and impairment charges including severance and severance related costs and exit costs, and certain other adjustments we believe are not reflective of our ongoing operations and performance. These items include acquisition costs and other fees, and shelf registration costs.

 18. FAIR VALUE OF FINANCIAL INSTRUMENTS
 Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
 Measurement of Fair Value
 Our material financial instruments consist primarily of cash and cash equivalents, investments in marketable and equity securities, trade and other payables, and long-term debt as follows:
 • Trade receivables—As of December 31, 2024 and 2023, we had $ 5.6 million and $ 0.6 million, respectively of trade receivable. As of December 31, 2024, $ 4.5 million consisted of trade receivables from provisional concentrate sales which are recorded at fair value based on Level 2 inputs. The remaining trade receivables approximate fair value due to their short-term nature and are based on Level 1 inputs.
 • Debt obligations—As of December 31, 2024 and 2023, we had $ 30.1 million and $ 0.2 million, respectively, of principal debt outstanding associated with our Credit Facility, insurance premium financing loan, and seller-financed loans for properties acquired at Carolina Lithium. The carrying value of our long-term debt approximates its estimated fair value, which are classified within level 2 of the fair value hierarchy. See Note 14—Debt Obligations.
 • Investments in marketable securities—As of December 31, 2024 we had $ 6.9 million and $ 0.0 million, respectively, of investments in marketable securities related to our shares in Atlantic Lithium, which were recorded at fair value based on Level 1 inputs. See Note 13—Other Assets and Liabilities.
 • Investments in equity securities—As of December 31, 2024 and 2023, we had $ 0.2 million and $ 0.5 million, respectively, of investments in equity securities related to our shares of Ricca, which were recorded at fair value based on Level 2 inputs. See Note 13—Other Assets and Liabilities.
 • Other financial instruments—The carrying amounts of cash and cash equivalents and trade and other payables approximate fair value due to their short-term nature and are based on Level 1 inputs.
 Level 3 activity was not material for all periods presented. There were no transfers between fair value levels during the years ended December 31, 2024 and 2023.

 19. COMMITMENTS AND CONTINGENCIES
 Legal Proceedings
 We are involved from time to time in various claims, proceedings, and litigation. We establish reserves for specific legal proceedings when we determine that the likelihood of an unfavorable outcome is probable, and the amount of loss can be reasonably estimated.
 In July 2021, a class of putative plaintiffs filed a lawsuit against us in the U.S. District Court for the Eastern District of New York claiming violations of the Exchange Act. The complaint alleged, among other things, that we made false and/or misleading statements and/or failed to make disclosure relating to proper and necessary permits. In February 2022, the Court appointed a lead plaintiff in this action, and the lead plaintiff filed an amended complaint in April 2022. On July 18, 2022, we moved to dismiss the amended complaint. On September 1, 2022, the lead plaintiff filed his Memorandum of Law in Opposition to our Motion to Dismiss. On October 7, 2022, we filed our Reply Memorandum in support of our Motion to Dismiss. On January 18, 2024, the Court granted our Motion to Dismiss the amended complaint. The lead plaintiff's deadline to appeal the decision of the Court expired.
 On July 5, 2022, Brad Thomascik, a purported shareholder of the Company's equity securities, filed a shareholder derivative lawsuit in the U.S. District Court for the Eastern District of New York. On behalf of the Company, the lawsuit purported to bring claims against certain of the Company's officers and directors. The complaint alleged that the defendants breached their fiduciary duties in connection with the Company's statements regarding the timing and status of government permits for Carolina Lithium in North Carolina at various times between March 16, 2018 and July 19, 2021. No litigation demand was made to the Company in connection with this action. The lawsuit focused on the same public statements as the shareholder derivative suit described below. In September 2022, the parties agreed to a stipulation to stay the proceeding pending resolution of the motion to dismiss in the securities law matters described above, and the Court ordered the case stayed in October 2022.
 On October 14, 2021, Vincent Varbaro, a purported holder of Piedmont Australia's American Depositary Shares and the Company's equity securities, filed a shareholder derivative suit in the U.S. District Court for the Eastern District of New York, purporting to bring claims on behalf of the Company against certain of the Company's officers and directors. The complaint alleged that the defendants breached their fiduciary duties in connection with the Company's statements regarding the timing and status of government permits for Carolina Lithium in North Carolina, at various times between March 16, 2018 and July 19, 2021.
