• Recognized a $1.4 million loss related to previously deferred debt issuance costs due to the suspension of the debt syndication process.
• The company's Common Stock price experienced substantial volatility during 2025, ranging from a high of $3.48 per share to a low of $0.46 per share.

Risks

• Business could be negatively impacted by inflationary pressures, resulting in increased operating costs and negatively affecting access to capital.
• Operating in a period of economic uncertainty and capital markets disruption, significantly impacted by geopolitical instability (e.g., Russia-Ukraine, Middle East conflicts), which could adversely affect the global economy, commodity prices, and financing availability.
• The planned graphite manufacturing business is significantly different from historic mining operations and carries risks such as unanticipated liabilities, the need for additional capital, intense competition (including from synthetic graphite and foreign companies), difficulty hiring personnel or acquiring intellectual property, and supply chain interruptions.
• Construction and operation of the Kellyton Graphite Plant are subject to delays, cost overruns, and the risk that it may not produce expected benefits or operate at commercial scale as anticipated.
• No committed source of financing for the development of graphite or vanadium projects, with approximately $117 million remaining for Phase I of the Kellyton Graphite Plant.
• As a pre-revenue company, it has incurred losses since 2009 and expects to continue incurring losses until the Kellyton Graphite Plant becomes operational, with no reliable source of operating cash.
• Volatility in graphite and vanadium prices may result in the company not receiving an adequate return on invested capital, and a significant, sustained drop could lead to asset impairment.
• Operations are subject to environmental risks, and compliance with evolving environmental laws and regulations may necessitate significant capital outlays or cause material changes or delays to intended activities.
• Competition from better-capitalized companies affects prices and the ability to acquire both properties and qualified personnel.
• Limited capital makes the company vulnerable to significant losses from manufacturing and mining risks, including environmental hazards, industrial accidents, and natural disasters, which larger competitors could more easily withstand.
• Dependence on experts and subject to workforce factors, including the ability to attract, train, and retain a skilled workforce, which could lead to increased compensation costs and operating challenges.
• Patent and other protective measures may not adequately protect proprietary intellectual property, and there is a risk of infringing on the rights of others, potentially leading to litigation and substantial costs.
• Pandemics, epidemics, or disease outbreaks may disrupt business, supply chains, and the business of partners, potentially affecting operations, liquidity, and results.
• Any reduction, elimination, or discriminatory application of government subsidies and economic incentives could diminish the competitiveness of the alternative fuel and electric vehicle industry, decreasing demand for graphite products.
• Future growth is partially dependent on the demand for, and consumer willingness to adopt, electric vehicles, which is influenced by various market perceptions and infrastructure factors.
• Changes to tariffs, anti-dumping and countervailing duties, or other trade regulations could materially alter relative pricing and competition for graphite products, reducing demand.
• The Coosa Graphite Deposit is in the exploration stage, with no assurance of establishing commercially exploitable Mineral Reserves, and if not, all exploration funds could be lost.
• The extent of the company's vanadium mineral reserves at the Coosa Graphite Deposit is unknown and may not be in sufficient quantities to make its extraction and processing economically feasible.
• May not be able to obtain surface or access rights to all or a portion of the Coosa Graphite Deposit, which could materially and adversely affect the timing, cost, or overall ability to develop mineral deposits.
• Mineral exploration and development activities are inherently risky, exposing the company to environmental liabilities and other dangers, with potential for inadequate insurance coverage.
• Title to the Coosa Graphite Deposit may be subject to defects or other claims, which could affect property rights and development.
• Failure to make timely payments under lease agreements for the Coosa Graphite Deposit could result in forfeiture of the company's interest.
• Stock price has been and may continue to be volatile, which may adversely impact investor confidence and increase the likelihood of securities class action litigation.
• No history of paying dividends on Common Stock, and no anticipation of paying dividends in the foreseeable future, requiring investors to rely on stock price appreciation for returns.
• Terms of subsequent financings may adversely impact holders of securities through dilution or the creation of senior claims on assets.
• Shareholders would be diluted if common stock is used to raise capital, and the perception that such sales may occur could cause the price of Common Stock to fall.

Future Outlook

The company expects to continue incurring cash losses until the Kellyton Graphite Plant becomes operational, with its operations dependent on securing additional funding to complete Phase I construction. It anticipates the Kellyton Graphite Plant will produce 12,500 mt/year of CSPG in Phase I, scaling to 50,000 mt/year in Phase II, and expects the Coosa Graphite Deposit to eventually provide natural graphite flake concentrate as feedstock. Plans include updating the Life Cycle Assessment for higher production volumes, evaluating additional products for Phase II, and exploring vanadium at Coosa. The company intends to prudently manage cash and liquidity while advancing its business plan, and management believes current cash is sufficient for non-discretionary expenditures beyond a year from the filing date.

Management Comments

• "Management notes that the original budget for Phase I was approximately $271 million and, through prior optimization and debottlenecking efforts, was reduced to approximately $245 million."
• "While the Company's additional optimization review in December 2025 resulted in additional potential cost reductions, the Company is also experiencing certain cost pressures related to tariffs and energy costs as a result of the current geopolitical climate and related uncertainties. As such, the Company is maintaining its current cost estimate of $245 million."
• "Management believes the Company's current cash balance is sufficient to fund its planned non-discretionary expenditures beyond a year after the date that this Annual Report on Form 10-K was issued."
• "FCA has indicated it may be open to considering a new arrangement with the Company, any future agreement would be subject to current market conditions and other terms to be negotiated."
• "The Company believes its patented approach supports the production of high-purity graphite and provides a competitive advantage as customers increasingly consider tariff restrictions, ESG, permitting and domestic supply chain requirements."

Industry Context

StockSavvy.ai notes that the termination of the FCA Offtake Agreement highlights the inherent volatility and competitive pressures within the rapidly evolving electric vehicle and battery materials market, where customer commitments can shift based on market conditions and strategic realignments. The increased net loss and paused debt syndication underscore the significant capital intensity and financing challenges faced by pre-revenue companies in the critical minerals sector, particularly when relying on specific commercial agreements for funding. The company's focus on developing a domestic supply of battery-grade graphite aligns with broader U.S. and EU policy initiatives aimed at reducing reliance on foreign imports, especially from China, which dominates global graphite output and anode production (76% of flake graphite, 90% of anodes). The patent for a non-hydrofluoric acid purification process positions Westwater favorably against industry standards, addressing growing ESG concerns and potentially benefiting from trade measures like anti-dumping and countervailing duties on Chinese imports, although the recent rescission of such duties by the ITC introduces uncertainty. The growth in LFP gigafactories in the U.S., as reported by Benchmark Minerals, suggests a strong underlying demand for graphite anodes, providing a favorable long-term market despite near-term policy and market fluctuations.

Comparison to Industry Standards

• Westwater's proprietary purification process, which avoids hydrofluoric acid, offers a more environmentally sustainable alternative compared to conventional purification techniques widely used by other graphite processing companies, particularly those in China.
• The company estimates its process emits approximately 10% less greenhouse gas (GHG) emissions than Chinese natural graphite processing methods and approximately 44% less GHG emissions than Chinese synthetic graphite processing methods, positioning it favorably in terms of environmental footprint.
• The Kellyton Graphite Plant is designed to recycle approximately 70% of the chemicals used in its purification process, demonstrating a commitment to resource efficiency that exceeds many traditional industry practices.
• The Coosa Graphite Deposit's preliminary economic analysis, based on a significant portion of Inferred Mineral Resources (89%), indicates a higher geological uncertainty compared to projects with a larger proportion of Measured or Indicated Mineral Resources, which are typically preferred for project financing and development.
• The termination of the FCA Offtake Agreement highlights the competitive landscape where major automotive manufacturers like Stellantis (FCA's parent) may re-evaluate supply agreements based on evolving market dynamics, similar to how other OEMs might adjust their sourcing strategies with battery suppliers like LG Energy Solution, SK On, and Samsung SDI.

Corporate Governance

Related Party Transactions

• Entered into voting agreements with certain officers and directors of the Company, pursuant to which each such officer and director agreed to vote shares of Common Stock held by such person in favor of stockholder proposals related to the issuance of conversion shares upon the future conversion of the Convertible Notes, if any, that would exceed 19.99% of the Company's issued and outstanding Common Stock.

Stakeholder Impact

• Shareholders face potential dilution from ongoing equity raises (ATM, Lincoln Park PA, Convertible Notes conversions) and continued stock price volatility. No dividends are anticipated in the foreseeable future.
• Employees benefit from the company's commitment to fostering solid relationships, fair treatment, safe working conditions, and professional development, along with employment benefits including medical insurance, paid time off, sick leave, retirement plans, and a bonus structure.
• Customers are impacted by the termination of the FCA Offtake Agreement, a significant potential customer, but the company continues engagement with SK On and Hiller Carbon and actively pursues new customer opportunities, focusing on meeting stringent technical specifications.
• Local communities in Coosa County, Alabama, where the Kellyton Graphite Plant and Coosa Graphite Deposit are located, are positively impacted by the company's commitment to being a good corporate citizen, safeguarding the environment, and engaging with local stakeholders through townhall meetings, first responder luncheons, and community service projects. The company also gives good-faith consideration to hiring local workers and purchasing from local contractors.
• Creditors face increased uncertainty due to the pausing of debt syndication efforts following the termination of the FCA Offtake Agreement. Holders of Convertible Notes are subject to financial covenants and potential 18% interest rates upon an event of default.

Next Steps

• Secure additional funding to complete construction of Phase I of the Kellyton Graphite Plant.
• Continue to provide samples and pursue additional customer opportunities for offtake agreements.
• Advance permitting for potential future mine development at the Coosa Graphite Deposit, including submitting a USACE Section 404 Individual Permit application in the second half of 2026.
• Update the Life Cycle Assessment (LCA) for the Kellyton Graphite Plant for the higher planned production of 12,500 mt of CSPG per year once the plant is operating.
• Evaluate the production of additional products in Phase II of the Kellyton Graphite Plant, subject to market demand and customer interest.
• Explore and evaluate vanadium at the Coosa Graphite Deposit for potential technical feasibility of extraction and processing.
• Continue efforts to evaluate and pursue other sources of government funding.
• Seek stockholder approval for the issuance of conversion shares exceeding 19.99% of outstanding Common Stock related to Convertible Notes.
• Initiate a U.S. Fish & Wildlife Service habitat assessment and cultural resource survey fieldwork for the Coosa Graphite Deposit.

Key Dates

Recommendation

Westwater Resources is in a critical development phase, marked by both significant progress and substantial challenges. The termination of the FCA offtake agreement and the resulting pause in debt syndication are major setbacks, contributing to a widened net loss and extending the timeline for the Kellyton Graphite Plant. While the company successfully raised substantial equity capital in 2025 and secured a patent for its purification process, the path to commercial production remains capital-intensive and uncertain. The preliminary economic analysis for the Coosa Graphite Deposit relies heavily on inferred resources, adding geological risk. Given the high operational risks, ongoing need for financing, and market volatility, a "Hold" recommendation is appropriate. Investors should monitor progress on securing new offtake agreements, restarting debt financing, and advancing the Coosa Graphite Deposit's permitting and resource definition before considering further investment.
