Key Risks 38 You should be aware that an investment under the Capital Raisings, being an investment in New Shares, involves various risks. This Section sets out some of the key risks associated with an investment in New Shares. A number of risks and uncertainties, which are both specific to Sayona and of a more general nature, may adversely affect the operating and financial performance or position of Sayona which in turn may affect the value of New Shares and the value of an investment in Sayona. There are also risks associated with the Transaction and each of the Capital Raisings, including those which are described below. The risks and uncertainties described below are not an exhaustive list of the risks facing Sayona, the Transaction, the Capital Raisings or associated with an investment in Sayona. Additional risks and uncertainties may also become important factors that adversely affect Sayona’s operating and financial performance or position. This document is not financial product advice and has been prepared without taking into account your investment objectives or personal circumstances. Before investing in New Shares, you should consider whether an investment in New Shares is suitable for you. Potential investors should consider publicly available information on Sayona, carefully consider their personal circumstances and consult their stockbroker, solicitor, accountant or other professional adviser before making an investment decision. Key Risk Overview Risks relating to Sayona Operational Safety Sayona is subject to extensive laws and regulations regarding occupational health and safety, and the risk of non-compliance with those laws and regulations may adversely impact Sayona’s operations, reputation, financial performance and financial position. All operations and development activities continue to have a strong focus on safe production and development. However, regardless of how carefully Sayona undertakes its operations, mining and exploration operations carry an inherent risk of liability and as such, these risks cannot be eliminated. Climate change risk Severe weather events and the challenges posed by climate change are inherently uncertain and have the potential to adversely affect Sayona’s operations and financial performance. While Sayona will endeavor to manage these risks and limit any consequential impacts, there can be no guarantee that Sayona’s operations and the value of its shares will not be impacted. Social and environment The operations and proposed activities of Sayona are subject to the laws and regulations concerning the environment and indigenous heritage. Sayona’s relations with local communities and First Nations people in the areas where its assets are located are important to its operations and may be affected by uncertain factors. It’s Sayona’s intention to conduct its activities to the highest standard of environmental and heritage obligations, including complying with all environmental laws or laws relating to the protection of indigenous heritage. Sayona actively engages with all stakeholders on a regular basis to better understand and address the individual needs of local communities and First Nations people. However, regardless of how carefully Sayona undertakes its operations, both mining and exploration operations carry an inherent risk of liability associated with, amongst other things damage to natural environment and indigenous heritage. If the compliance costs of such legislation become so significant as to impact Sayona’s costs of carrying on business, this may also have an impact on the future value of Sayona’s shares.

Key Risks 38 Key Risk Overview Risks relating to Sayona Operational performance Sayona’s operations may not deliver a safe, stable and predictable operational performance and consequently have a negative impact on Sayona and its shares. Major external events or natural disasters Sayona’s projects now or in the future are susceptible to certain physical and other risks, including natural disasters, environmental hazards, pandemics and other catastrophic events, which could disrupt production and have a material adverse effect on Sayona’s financial and operational performance. Whilst Sayona has contingencies and plans in place to ameliorate these risks, such events or natural disasters carry an inherent risk of damage to site infrastructure or transport/energy related infrastructure and may cause disruption to services and supplies and access to site by employees. These events may significantly impact on Sayona’s operations. Projects fail to deliver Sayona has a considerable portfolio of development assets. All projects have inherent delay and cost risks, particularly in the current challenging global market (low lithium pricing, geopolitical instability, logistics, inflation, skilled labour availability, etc.). Whilst Sayona is focussed on de-risking the development of these projects, there is no guarantee that such projects meet current expectations or forecasts. Commodity Prices The prices of commodities, including lithium, are volatile and such volatility may negatively affect Sayona’s revenue and cash flows. Commodity prices fluctuate and are affected by many factors beyond Sayona’s control, such as inflation, interest rates and currency exchange. The price of lithium and the global demand for lithium is also reactive to supply and demand fluctuations. Such fluctuations are influenced by various factors, including the level of consumer demand, potential distribution problems, technological advances, availability of alternatives, global economic and political developments, forward-selling activities and other macro-economic factors. In particular, the demand for lithium is also dependent upon the demand for lithium batteries and battery electric vehicles. Any one of these factors may affect the price of, or demand for, lithium, which in turn may affect the price that Sayona is able to obtain for lithium or the amount of lithium that Sayona can sell. Market changes in lithium industry The growth of Sayona’s business, as well as Sayona’s financial condition and financial performance, are dependent on the continued growth in demand for electric vehicles, the growth in demand for lithium chemicals and the growth of the lithium markets generally. Macro risk General economic conditions may adversely impact Sayona’s operating and financial performance and financial position, including its future revenues and share price. Sayona’s operating and financial performance is influenced by a variety of general economic and business conditions, including consumer spending levels, lithium prices, inflation, interest and exchange rates, supply and demand trends, key customer concentration, industrial disruption, availability of debt and capital markets, and government fiscal, monetary and regulatory policies.

Key Risks 38 Key Risk Overview Risks relating to Sayona Geopolitical risk Global and local conflicts, including the tensions between China and Taiwan, the war in Ukraine and the conflict in Israel, could adversely impact Sayona’s operations, financial performance and financial position. Political risk Sayona’s financial performance, operations, share price and profitability may be adversely affected due to circumstances in the countries where Sayona operates, particularly in Canada. To conduct its business, Sayona must obtain various governmental licenses, permits, authorisations, concessions and other approvals in connection with its activities in relevant jurisdictions, including Canada and Australia. Such approvals are related to the laws and regulations that govern prospecting, developing, mining, production, exports, taxes, labour standards, occupational health, waste disposal, toxic substances, land use, surface rights, environmental protection, safety and other matters. Changes in political, regulatory, or fiscal frameworks in these countries could adversely impact Sayona’s financial performance, operations, share price and profitability. Liquidity risk – debt and capital markets Sayona’s operations and development plans may require additional funding or capital for future activities. There is no certainty that Sayona will be able to secure debt, equity funding or alternative means of funding on favourable terms or at all. If Sayona is unable to secure adequate external funding or capital on acceptable terms, or at all, its development and expansion plans may be adversely affected. This may impact the value of Sayona’s shares. Staffing and key management personnel Sayona’s operations, financial performance and financial position are dependent on attracting and retaining qualified key personnel. Sayona relies on the experience, skills and knowledge of its key personnel in Canada and Australia to successfully manage its business. The availability and retention of skilled personnel is highly competitive in the current market, particularly in Canada with current mining industry growth in certain sectors. Sayona relies heavily on critical executive and senior management level individuals, as well as those with niche technical skills. The inability to attract and retain key personnel, including personnel with technical skills, or the unexpected loss of such personnel may adversely affect Sayona’s operations, financial performance and financial position. Sayona’s upcoming AGM on 28 November 2024 includes a spill resolution, which provides that shareholders may vote to allow for a spill meeting to occur within 90 days of the AGM. If this resolution passes, the non-executive directors currently in place will be replaced before completion of the Merger and there will be a loss of continuity of input from those directors. Fraud, corruption and misconduct Sayona’s reputation, business and financial performance may be materially and adversely impacted by fraud or violations of anti-bribery and anti-corruption laws.

Key Risks 38 Key Risk Overview Risks relating to Sayona Royalty claims Many of the mining claims of which Sayona has an interest are subject to ongoing royalty obligations. The amount of the royalties payable in respect of a claim may have an impact on the economic viability of that claim, depending on various factors such as commodity prices and prevailing economic conditions. The amount of royalties payable may impact on profitability of Sayona and consequently impact on the value of Sayona’s shares. Resource estimate Resource estimates are expressions of judgement based on knowledge, experience and industry practice. Estimates which were valid when originally calculated may alter significantly when new information or techniques become available. In addition, by their very nature, resource estimates are imprecise and depend to some extent on interpretations, which may prove to be inaccurate. As further information becomes available through additional fieldwork and analysis, the estimates are likely to change. This may result in alterations to development and mining plans which may, in turn, adversely affect Sayona’s operations. This may impact on Sayona’s future profitability any consequently the value of Sayona’s shares. Exploration risk Exploration for mineral resources is highly speculative. There is no assurance that exploration of the tenement portfolio in which Sayona has an interest, will result in the discovery of a mineral deposit let alone one that results in an increase of Sayona’s current mineral resource, or the conversion of any of Sayona’s mineral resources to ore reserves. Further, there is no certainty that any of the minerals discovered will be able to be economically recovered. In particular, the success of Sayona’s future exploration activities may be affected by a range of factors including geological conditions, limitations on activities due to seasonal weather patterns, unanticipated operational and technical difficulties, industrial and environmental accidents, changing government regulations and may other factors beyond the control of Sayona. Further the exploration costs of Sayona are based on certain assumptions with respect to the method and timing of exploration. By their nature, these estimates and assumptions are subject to significant uncertainties and accordingly, the actual costs may differ materially from these estimates and assumptions. Sayona will need access to ongoing sources of capital in order to progress its exploration program. Sayona’s inability to exploit its exploration assets, may impact on the future value of Sayona’s shares. Land access From time to time, Sayona’s tenements, or tenements Sayona has legal or beneficial interest in, may be subject to access restrictions. These may relate to the freehold owner of the land on which the tenements are located, or the rights of indigenous people. In those circumstances, Sayona may have to resolve access arrangements under the relevant regime prior to entering upon the land to carry out activities or developing a mine on the tenements. Access arrangements may be subject to the provision of monetary compensation, compensation for damage to land, and restoration of the land. There can be no guarantee that applications or access arrangements will be resolved in a timely fashion, in Sayona’s favour, or in a manner that is commercially viable for Sayona. Sayona’s inability to resolve access issues on satisfactory terms, may impact its operations, and particularly its exploration program. If access issues are not resolved satisfactorily, this may impact on the future value of Sayona’s shares.

Key Risks 38 Key Risk Overview Risks relating to Sayona Taxation Changes to corporate income tax, import duties, property tax, excise tax, withholding tax or any other applicable taxation legislation or policies relevant to Sayona may adversely affect Sayona’s financial profitability, net assets and cash flow and the returns to investors. Litigation Legal proceedings may arise from time to time in the course of Sayona’s business. Sayona may be involved in disputes with other parties which may result in litigation. Any such claim or dispute, if proven, may impact adversely on Sayona’s operations, financial performance and financial position. Insurance There are significant exploration and operating risks associated with lithium exploration and mining, including adverse weather conditions, environmental risks and fire, all of which can result in injury to persons as well as damage to or destruction of the plant, equipment, production facilities and other property. Sayona is also subject to environmental risks such as pollution and environmental damage. Should a significant event occur where Sayona is not fully insured there could be a negative impact on Sayona. In addition, in the future, some or all of Sayona’s insurance coverage may become unavailable or prohibitively expensive. Risks relating to the Transaction Transaction may not complete or may be delayed Completion of the Transaction is conditional on various matters including shareholder approval from both Sayona and Piedmont. Refer to the ASX announcement in relation to the Transaction and Capital Raisings released by Sayona to ASX on the same date as this presentation for further information regarding the material conditions for the Transaction. There can be no certainty, nor can Sayona provide any assurance or guarantee, that these conditions will be satisfied or waived or, if satisfied or waived, when that will occur. If for any reason any of the conditions are not satisfied or waived (where capable of being waived) by the time required, completion of the Transaction (Completion) may be delayed or may not occur on the current terms or at all. Sayona will have incurred significant transaction costs in relation to the Transaction even if it does not proceed and these costs may include a reverse break fee of $[X] payable by Sayona in certain circumstances to Piedmont. There is a risk that the transaction costs associated with the Transaction (whether it completes or not) results in Sayona not achieving the earnings guidance it has previously provided to the market. There may be other adverse consequences for Sayona and Sayona shareholders if Completion does not occur, including that the trading price of Sayona’s shares may be materially adversely affected and the anticipated synergies and other benefits that Sayona expects to achieve from the Transaction will not be realised. If Completion is delayed, Sayona may incur additional costs and it may take longer than anticipated for MergeCo to realise the benefits of the Transaction. Any failure to complete or delay in completing the Transaction could materially and adversely affect the price of Sayona’s shares.

Key Risks 38 Key Risk Overview Risks relating to the Transaction Scrip component of merger consideration As part of the Transaction, Piedmont shareholders will receive consideration in the form of fully paid ordinary shares in Sayona. Existing Sayona shareholders and new investors who take up shares under the Capital Raisings will have their shareholding significantly diluted by the issue of the shares to the Piedmont shareholders. Immediately after Completion, it is expected that Sayona and Piedmont shareholders will own approximately [50%] / [50%] of the shares in MergeCo respectively (on a fully diluted basis). Reliance on information provided Sayona undertook a due diligence process in respect of the Transaction, which relied in part on legal, financial, taxation, synergies and operational due diligence on information provided by or on behalf of Piedmont. If any such information provided to, and relied upon by, Sayona in its due diligence, and in its preparation of this presentation and other materials given to ASX, proves to be incorrect, incomplete or misleading, or if any of those due diligence enquiries failed to identify potential issues, there is a risk that the actual financial position and performance of Piedmont may be materially different to Sayona’s understanding, or the realisable synergies from the Transaction will be less than anticipated including those reflected in this presentation. Either of these could have a material adverse effect on MergeCo’s financial condition or performance. There is also a risk that the due diligence conducted has not identified issues that would have been material to the decision to enter into the Transaction, or that certain potential issues identified as part of Sayona’s due diligence may not have been accurately assessed or quantified or are not possible to quantify or for which sufficient protection is not provided for in the Transaction Agreement. A material adverse issue that was not identified prior to entry into the Transaction (or an issue that later proves to be more material than first anticipated) could have an adverse impact on the reputation, financial performance or operations of Sayona (for example, Sayona may later discover Piedmont liabilities or defects which were not identified through due diligence, are more than initially identified through due diligence, or for which there is no contractual protection). Due diligence cannot uncover all potential issues or historical non- compliance by a merger partner, and reliance has, by necessity, been placed by those undertaking due diligence on the accuracy of information and confirmations provided by Piedmont and its representatives. Further, as is usual in undertaking mergers and acquisitions, the due diligence process undertaken identified a number of risks associated with Piedmont, which Sayona had to evaluate and manage. Certain risks cannot be avoided or managed appropriately and the mechanisms used to manage these risks included in certain circumstances the acceptance of the risk as tolerable on commercial grounds such as materiality. There is a risk that the approach taken by Sayona may be insufficient to mitigate the risk, or that the materiality of these risks may have been underestimated or unforeseen or for which there is no contractual protection, and hence they may have a material adverse impact on Sayona’s operations, earnings and financial position. The information reviewed by Sayona included forward looking information. While Sayona has been able to review some of the foundations for the forward- looking information relating to Piedmont, forward looking information is inherently unreliable and based on assumptions that may change in the future.

Key Risks 38 Key Risk Overview Risks relating to the Transaction Integration risk and realisation of synergies The integration of two businesses of the size and nature of Sayona and Piedmont carries risk, including potential delays or costs in implementing necessary changes and difficulties in integrating various operations and systems. The success of the Transaction, and the ability to realise the expected benefits of the Transaction outlined in this presentation, is dependent on the effective and timely integration of Sayona and Piedmont following Completion. There is a risk that integration could take longer, be more complex or cost more than expected, encounter unexpected challenges or issues (including differences in corporate culture loss of, or reduction in, key personnel, expert capability or employee productivity, or failure to procure or retain employees of Sayona, require changes to operating models), or divert the attention of management, which impact on the integration process (which in turn could cause the anticipated benefits and synergies of the integration of Sayona and Piedmont being less than estimated). Integration risk and realisation of synergies (cont’d) A failure to integrate the businesses in the time and manner contemplated by Sayona or a failure to achieve the targeted synergies of integration may impact on the financial performance, operation and position of Sayona. Furthermore, Piedmont will be a material part of MergeCo’s business upon acquisition. If the Piedmont business does not perform as expected, this could have a material adverse impact Sayon’s financial position and performance. Historical liabilities of Piedmont Lithium If the Transaction completes, Sayona may become directly or indirectly exposed to liabilities that Piedmont may have incurred or is liable for in the past as a result of prior acts or omissions, including liabilities which were not identified during the due diligence enquiries or which are greater than expected, or for which were accepted as a tolerable risk. Such liabilities may adversely affect the financial performance or position of Sayona after the Transaction. Piedmont has its own corporate, tax, regulatory and risks frameworks. However, there is a risk that Piedmont’s existing frameworks were inadequate. For example, if Piedmont’s ‘s tax and regulatory frameworks were inadequate, there is a risk that Piedmont has not properly identified and responded to changes in tax laws or other laws and regulations which apply to it. There is a risk that Sayona could be exposed to unexpected liabilities resulting from past non-compliances by Sayona with applicable laws or regulations, which may impact on the financial performance or position of Sayona. It may also have other impacts, such as attracting greater scrutiny from regulators or cause reputational damage.

Key Risks 38 Key Risk Overview Risks relating to the Transaction Analysis of merger opportunity Sayona has undertaken financial, tax, legal, commercial and technical analysis of Piedmont in order to determine its attractiveness to Sayona and whether to proceed with the Transaction. It is possible that despite such analysis and the best estimate assumptions made by Sayona, the conclusions drawn are inaccurate or are not realised. While Sayona has undertaken analysis in relation to the expected benefits of the Transaction, including synergies, they remain Sayon’s estimate of the benefits expected to be achieveable, and there is a risk that the actual benefits may be less than expected or delayed, or that the expected benefits may not materialise at all or cost more to achieve than originally expected. To the extent that the actual results achieved by the Transaction are different to those indicated by Sayona’s analysis, there is a risk that the performance of Sayona following the Transaction may be different (including in a materially adverse way) from what is reflected in this presentation. There is also a risk that Sayona’s assessment of matters such as the taxation consequences of the Transaction is challenged by revenue authorities, which can involve future expenditure to consider and defend such challenges or to meet any additional costs or claims. Integration of accounting policies and methods Sayona and Piedmont, as standalone entities, have particular accounting policies and methods which are fundamental to how they record and report their financial position and results of operations. Sayona and Piedmont may have exercised judgment in selecting accounting policies or methods, which might have been reasonable in the circumstances yet might have resulted in reporting materially different outcomes than would have been reported under the other company’s policies and methods. The integration of Sayona and Piedmont’s accounting functions may lead to revisions of these accounting policies, which may adversely impact MergeCo’s reported results of operations and/or financial position and performance. Year-end reporting periods will be aligned post implementation of the Transaction. Price of shares may fluctuate Sayona’s shares are freely tradeable on the ASX. The price at which the shares trade following completion of the Transaction will be affected by the financial performance of MergeCo and by external factors unrelated to the operating performance of the MergeCo, including movements on international share markets, the level of interest rates, exchange rates and commodity prices, general domestic and international economic conditions and government policies relating to taxation and other matters. Foreign exchange risk and foreign regulations The Transaction includes the acquisition of controlling interests in overseas entities that operate in foreign jurisdictions. These entities transact in the local currencies of the countries in which they are domiciled. The value of a financial asset, liability, commitment or earnings held or transacted in foreign currency may be impacted by changes in currency exchange rates. The overseas operations of Piedmont are also subject to the laws of those countries and could be adversely impacted by changes to laws or regulations in those countries in the future.

Key Risks 38 Key Risk Overview Transaction risks Alignment of year ends and acquisition accounting Sayona and Piedmont have different year end reporting periods with Sayona reporting on a year ended 30 June basis and Piedmont using 31 December. The application of acquisition accounting and the alignment of financial year ends will likely impact MergeCo’s reported results of operations and/or financial position and performance Risks associated with the Capital Raisings General investment risks An investment in Sayona is subject to risks, some of which are beyond the control of Sayona. The existence of risk means that the performance of Sayona could be adversely affected Sayona does not guarantee any particular rate of return or the performance of Sayona’s shares. Some of the factors which may adversely impact the price of Sayona shares include: General movements in Australian and international stock markets; Commodity prices; Investor sentiment; Australian and international economic conditions and outlook; Changes in interest rates and the rate of inflation; Change in government regulation and policies; Announcement of new technologies; and Geo-political stability, including international hostilities and acts of terrorism. The risks outlined above, together with other general risks, are applicable to all investments in listed securities not specifically referred to, may affect the value of shares in Sayona (including New Shares) in the future. There is no guarantee that the New Shares will make a return on the capital invested or that there will be an increase in the value of the New Shares in the future. This Section should be treated as a general guide to possible risks only. While Sayona may be able to minimise the impact of some risks through various risk management techniques, many of the risks identified in this Section are beyond the control of Sayona and as such cannot be eliminated or their impact minimised.

Key Risks 38 Key Risk Overview Risks associated with the Capital Raisings Share price and liquidity Sayona is subject to the general market risks inherent in all securities traded on a stock exchange. The market price for Sayona’s shares may fluctuate over time as a result of a number of factors, including it financial performance and prospects, prevailing market conditions, commodity prices and foreign exchange movements, general investor sentiment, inflation, geo-political conditions, fiscal policy and interest rate rises, as well as the liquidity and volume of the shares being bought or sold at any point in time. Sayona’s shares may therefore rise above or below the current share price, or the offer price, depending on its financial performance and various other factors which are outside of its control. No dividend or other distribution in the near term Sayona’s directors do not in the near term intend to pay profits of Sayona out in the form of dividends or other distributions but will instead reinvest those amounts into development of the business. Accordingly, any investment in Sayona’s shares may not carry with it income returns in the form of dividends or other distributions and any returns will be limited to any capital growth arising from any increase in the price of Sayona shares. Underwriting risk Sayona has entered into a Placement Agreement under which the Lead Manager has agreed to fully underwrite the Unconditional Placement and lead manage the Conditional Placement (together, the “Placement”), subject to the terms and conditions of the Placement Agreement. If certain conditions are not satisfied (including, in relation to the Conditional Placement, that RCF VIII does not pay and subscribe for the New Shares the subject of the subscription agreement between RCF VIII and Sayona) or certain events occur, the Lead Manager may terminate the Placement Agreement (for further information, see Summary of Sayona Placement Agreement slides). The ability of the Lead Manager to terminate the Placement Agreement in respect of certain events will depend on whether the Lead Manager has reasonable grounds to believe that such event, matter or circumstance has or is likely to have a material adverse effect on the financial position or prospects of the Sayona group or the outcome or success of the Placement (or any part of it) or the market price of, or ability to settle the Placement of, any of the Placement Shares, or could give rise to a contravention by the Lead Manager (or one of its affiliates) of (or the involvement of the Lead Manager in a contravention of) or liability of the Lead Manager (or one of its affiliates) under the Corporations Act or any other applicable law.
