Sayona Annual Report 2025 6

Dear shareholders, It is my pleasure to detail what has been a defining year in Sayona’s journey. FY25 was a period marked by strong operational performance, strategic progress, and the positioning of our business for long-term growth in the global lithium supply chain. A significant improvement in our safety performance was a highlight as were the gains made in relation to our environmental and sustainability metrics. We delivered on every one of our full-year guidance metrics — including a 31% increase in annual production and a 9% reduction in unit operating cost sold compared to FY24 — while achieving critical operational and developmental milestones across our assets. Most importantly, we set the stage for a transformative merger with Piedmont Lithium, forming what will become Elevra Lithium Limited. Corporate In November 2024, we announced our definitive agreement to merge with Piedmont Lithium — a strategic move to combine complementary assets, unlock synergies, and create a globally significant lithium company. The merged entity will be named Elevra Lithium Limited and the Board of Elevra includes distinguished nominees from each company with deep industry, technical, and capital markets expertise. We also: • Completed a successful capital raise, securing $38 million in net proceeds to support growth initiatives. • Welcomed Laurie Lefcourt to our Board of Directors, strengthening governance as we enter a new phase. • Finalised drilling at NAL and Moblan and turned our focus to the operation and development of each asset. • Realised strong pricing outcomes through our forward sales strategy, with average realised prices exceeding market benchmarks. North American Lithium FY25 was a year of strong operational improvements at our flagship North American Lithium operation. We began the year by improving safety performance. Notably, we recorded our first Triple-Zero month for safety — a testament to the operational leadership at NAL. As the year progressed, NAL consistently improved mill utilisation and recovery. Quarterly records were set in mill utilisation (93%) and lithium recovery (73%), with May 2025 marking our highest-ever monthly production at 19,895 tonnes. Optimisation of the flotation process and the improved availability of crushed material contributed to these outstanding results. On the logistics front, through strategic collaboration with Piedmont Lithium, we also began realising tangible benefits from pooled shipments, reducing our shipping costs and increasing efficiency. Despite weather-related downtime in early 2025, we quickly responded by deploying additional mobile crushing capacity. We also maintained stable unit operating costs, finishing the last quarter of the financial year with a low of US$737 per tonne produced, further strengthening NAL’s cost competitiveness. Additionally, we finalised a robust drilling program totalling 53,444 metres across 153 holes (over CY24) and completed a review of Reserves and Resources which have increased to 48.6Mt @ 1.11% Li2O and 95Mt @ 1.15% Li2O respectively. In light of the material increase in the size of NAL, we have launched environmental and engineering studies to support a potential expansion of the operation. These are critical steps as we plan for the next phase of growth at NAL. Chief Executive Officer’s Review Sayona Annual Report 2025 7

Moblan Lithium Project Moblan continues to emerge as one of North America’s most promising undeveloped lithium resources. A comprehensive drill program was completed during CY24 comprising 76,202 metres across 281 holes. Incorporation of this drilling saw our JORC-compliant MRE increase 30% to 121 million tonnes (Mt) at 1.19% Li2O, reinforcing Moblan’s strategic value to our portfolio. We have also reviewed the Reserves at Moblan which have increased 39% to 48Mt at 1.31% Li2O. These results represent a more than 650% increase in resource and 340% increase in reserves since Moblan was acquired in 2021. Considering the inherent value of this asset we have launched a tender process for permit-related studies for project development, with more than a dozen parties expressing interest across six work packages. Looking Ahead As we look ahead, Sayona stands on the threshold of an exciting new chapter. With Sayona shareholders having approved the merger with Piedmont Lithium, we are advancing toward the formation of Elevra Lithium — a premier lithium company with a leading position in the North American lithium supply chain. The combination of Sayona and Piedmont’s complementary assets, technical teams, and market strategies will create significant operational and commercial synergies. Together, we will be better positioned to meet surging global demand for lithium and deliver long-term value to our stakeholders. At the same time, we remain firmly focused on unlocking further potential within our current portfolio. In particular, we are progressing critical development work for a potential brownfield expansion at North American Lithium. The expansion has the potential to significantly increase NAL’s scale and improve unit economics while further strengthening Québec’s role as a cornerstone of the global battery materials supply chain. As we move into FY26, our priorities are clear: complete the transition to Elevra Lithium and execute on our growth pipeline. With a talented and committed team, a clear strategy, and the momentum of a transformational year behind us, we are well-positioned to lead the next phase of operational performance and growth.

Review of Financial Performance 2025 was a year of record production for Sayona. The Company delivered strong operational performance, progressing the ramp-up of production at North American Lithium (NAL) which rose 31% compared to FY24. This was supported by continued improvements in safety, sustainability, and operational efficiency, including a 9% reduction in unit operating costs. Key Data Revenue $223 million Revenue for the year ended 30 June 2025 Cash Flows Used in Operations ($15) million Net cash flows used in operating activities for the year ended 30 June 2025 Cash $72 million Cash and cash equivalents of the Group as at 30 June 2025 Underlying EBITDA ($67) million Underlying EBITDA for the year ended 30 June 2025 Capital Investment $50 million Capital expenditure and exploration investment for the year ended 30 June 2025 Net Assets $475 million Net assets of the Group as at 30 June 2025 Sayona advanced its strategic capital investment program across the Québec lithium projects, strengthening its mineral resource base and completing infrastructure upgrades at NAL to position the operation for long-term success. The year also marked a defining strategic milestone with the announcement of Sayona’s merger with Piedmont Lithium. This transformative transaction will create Elevra Lithium, a globally significant lithium company with a world-class portfolio, expanded growth opportunities, and enhanced access to global capital markets. Sayona closed FY25 in a solid financial position and the business is well placed to capture value from the accelerating global demand for lithium. Sayona Annual Report 2025 14

Financial Performance Revenue for the year ended 30 June 2025 increased by 11 per cent to $223 million (30 June 2024: $201 million), driven by a 32 per cent increase in spodumene concentrate sales volumes, offset by a 16 per cent decrease in average realised selling prices related to adverse lithium market conditions. Lower prices were realised despite significant savings achieved in seaborne freight costs from pooled cargos in addition to pricing gains from the forward sales program. The underlying EBITDA loss for the year was $67 million, resulting from increased sales volumes of higher cost inventory carried over from the NAL operational ramp-up phase, which was partly offset by cost savings at the operational and corporate level. The Group’s consolidated loss after income tax for the year ended 30 June 2025 was $382 million (30 June 2024: $119 million loss), which included income from the sale of tax benefits under flow through share arrangements of $6 million (30 June 2024: $5 million) and non-recurring merger transaction costs of $13 million (30 June 2024: nil). The Group also recorded an impairment of the assets of North American Lithium of $271 million as at 30 June 2025 (30 June 2024: $4 million) due to a decline in forecast long-term lithium prices. The Group has reviewed the carrying value of the NAL Cash Generating Unit (CGU) as of 30 June 2025 as required under the Accounting Standards. The softening of the forward lithium prices over the past 12 months combined with the Company’s limited ability to take advantage of any upswings in forward lithium prices due to onerous conditions in the offtake agreement with Piedmont have been major factors in recognising the $271 million impairment charge against the NAL assets. Once the merger with Piedmont is completed, the impact of the offtake agreement will no longer be a factor in assessing future recoverable amounts for NAL’s assets. Cash Flows and Liquidity The Group recorded a net cash outflow from operating activities of $15 million for the year, which was a 76 per cent reduction on the operating cash outflow compared to the prior year. Cash outflows for capital expenditure and capitalised exploration expenditure was $50 million during the year, a decrease of 56 per cent compared to the prior year. Capital expenditure at NAL focused predominantly on sustaining capital projects, whilst the remaining Flow Through Share funding was expended on exploration drilling at NAL and Moblan. Cash and cash equivalents at the end of the period decreased by $18 million to $72 million at 30 June 2025, mainly due to the net cash outflow from operating activities and sustaining capital expenditure at NAL, which was partly offset by receipts from non-controlling interests and proceeds from a capital raise completed in November 2024.

FY25 in Review The 2025 financial year marked a significant turning point for the North American Lithium operation. The year was defined by improved safety and production performance, record performance milestones, and laying the foundation for a potential future expansion of the facility. Having restarted operations in early 2023, NAL transitioned from commissioning to full-scale production during FY24 and then focused on optimisation and stabilisation in FY25. Through strong collaboration between Sayona’s operational teams and joint venture partner Piedmont Lithium, NAL achieved key technical and operational milestones that underscore the asset’s long-term strategic value. Notable highlights from the year include: • Achievement of record monthly production in May 2025, with 19,895 tonnes of spodumene concentrate produced. • Highest-ever mill utilisation of 93% and lithium recovery of 73% in the June Quarter, demonstrating significant process improvements. • Execution of a 53,444 metre(1) drilling program to support resource expansion and resource classification upgrades. • The launch of environmental and engineering studies related to a potential brownfield expansion. While the operation experienced temporary processing disruptions due to unseasonal weather events early in calendar year 2025, rapid response measures ensured minimal impact on full-year production targets. By year-end, NAL demonstrated its ability to deliver sustained, efficient output, positioning itself as a key pillar in the future of the North American lithium supply chain. Highlights Record monthly production of spodumene concentrate 19,895 tonnes (May 2025) Highest-ever mill utilisation (June Quarter) 93% Record lithium recovery (June Quarter) 73% Drilling for resource expansion 53,444 metres(1) over 153 holes Environmental and engineering studies Potential brownfield expansion Through strong collaboration between Sayona’s operational teams and joint venture partner Piedmont Lithium, NAL achieved key technical and operational milestones that underscore the asset’s long-term strategic value.

Spodumene Concentrate Production (dmt) 1,250 1,300 1,350 1,400 1,450 FY24 1,417 1,290 FY25 1,200 9% 220,000 FY24 155,822 204,858 FY25 100,000 120,000 140,000 160,000 180,000 200,000 31% Unit Operating Cost Sold (FOB) Operational and Financial Performance FY25 saw meaningful gains across nearly every key production metric. Total spodumene concentrate production increased throughout the year, with record quarterly output in the June quarter and the May 2025 monthly production total of 19,895 tonnes marked a new benchmark for the operation. Recovery rates improved steadily due to optimisation of the flotation circuits and improvements in feed consistency. In the June quarter the operation achieved a record lithium recovery of 73%. Mill utilisation reached 93%, driven by improvements in equipment reliability and the efforts of the operational team. To address unplanned downtime, a mobile crushing unit was mobilised in the March quarter to aid the Crushed Ore Dome’s ability to stabilise feed availability. NAL’s improved process performance also translated into strong cost control. Unit operating costs finished the year at US$737 per tonne on a units produced basis in the June Quarter and full year unit operating cost sold declined by 9% compared to FY24. Ongoing implementation of cost improvement strategies — particularly related to logistics — played a key role in delivering the cost reduction. These cost reductions are expected to deepen following the completion of the Sayona-Piedmont merger. Development and Expansion To support potential long-term growth at NAL, Sayona undertook several key initiatives during FY25: • A 53,444 metre drill program across 153 holes was completed, targeting resource growth and increases in reserves. Subsequent to the end of the fiscal year we have completed a review of Reserves and Resources which have increased to 48.6Mt @ 1.11% Li2O and 95Mt @ 1.15% Li2O respectively. • Environmental baseline studies and engineering assessments were launched to support a brownfield expansion scenario, which could increase annual plant throughput beyond its current capacity. • Initial scoping indicates that expanded output could be achieved with incremental infrastructure upgrades, particularly in crushing, grinding, and tailings management. These efforts represent the next step in maximising NAL’s value and cementing its role as a long-term supplier to the North American EV and battery markets. FY25 saw meaningful gains across nearly every key production metric. Sayona Annual Report 2025 19

FY25 in Review FY25 was a pivotal year for the Moblan Lithium Project, solidifying its status as one of North America’s largest and highest-quality undeveloped lithium deposits. Through sustained exploration success, increased resource confidence, and early-stage development progress, Sayona advanced Moblan from a growth-stage asset into a strategic cornerstone of its long-term portfolio. Located in the Eeyou Istchee James Bay region of Québec, the Moblan Lithium Project is jointly owned by Sayona (60%) and Investissement Québec (40%). With proximity to existing infrastructure, hydropower, and key transport corridors, Moblan is well positioned to become a future large-scale, low-cost supplier of spodumene concentrate to global markets. FY25 highlights included: • Completion of a 76,202 metre(1) drill program over 281 holes — one of the largest lithium exploration programs in Québec to date. • Launch of tenders for key environmental studies, including permit-related baseline work and stakeholder engagement with Cree Nation partners. Subsequent to the end of the fiscal year Reserves and Resources which have increased to 48Mt @ 1.31% Li2O and 121Mt @ 1.19% Li2O respectively. As global demand for high-purity lithium feedstock continues to rise, Moblan has emerged as a core element of Sayona’s medium- to long-term growth strategy. The project is also strongly aligned with Québec’s ambitions to become a leader in green battery materials supply, reinforcing its strategic and socio-economic importance. Highlights August 2025 JORC-compliant Mineral Resource Estimate (MRE) 121Mt at 1.19% Drilling for resource expansion 76,202 metres(1) over 281 holes Launch of tenders Tenders for key environmental studies As global demand for high-purity lithium feedstock continues to rise, Moblan has emerged as a core element of Sayona’s medium-to long-term growth strategy. Moblan Lithium Project Sayona (1) Over calendar year 2024. Annual Report 2025 20

Mineral Resource Growth The updated Mineral Resource Estimate, released in August 2025, marked a major milestone in Moblan’s evolution: • 121Mt @ 1.19% Li2O, classified as 107.7Mt Measured and Indicated and 13.3Mt Inferred. • This update represents more than 650% increase in tonnage compared to the tonnage when Moblan was acquired in 2021, driven primarily by successful step-out drilling and increased geological continuity across the deposit. • Drilling confirmed that mineralisation remains open along strike and at depth, indicating strong potential for future resource growth. The CY24 drill program of 76,202 metre included extension drilling in underexplored zones, infill drilling to convert Inferred to Indicated resources, geotechnical drilling to support mine design, and hydrogeological holes to inform water management strategies. Project Development Activities Moblan’s transition from exploration to development was also advanced during FY25, with a number of key workstreams launched: • The tender process for environmental and permitting studies commenced which will include data collection for baseline wildlife, water, noise, and air quality metrics. These studies will feed into the environmental and regulatory approvals required under Québec and Federal regulations. • Engagement continued with local Cree communities. A collaborative approach to long-term economic participation, environmental stewardship, and cultural respect remains a cornerstone of the project’s development strategy. Moblan represents a key source of growth and value creation for Sayona and its stakeholders. The scale, grade, and jurisdictional advantages of this asset uniquely position it to meet future lithium demand from North American and global battery markets. Sayona Annual Report 2025 21

FY25 in Review In FY25, Sayona maintained its regional lithium exploration portfolio in Québec with targeted exploration, resource growth assessments, and prospecting programs across several key tenements. These projects play a critical role in supporting Sayona’s long-term strategy, with the potential to provide satellite feed or future standalone development opportunities. Authier Lithium Project 24 claims, 884ha The Authier Lithium Project in Québec is a hard rock spodumene lithium deposit set to play a key role in the Company’s multi-project Abitibi-Témiscamingue Hub, providing supplementary ore for processing at NAL. The project is located approximately 70 kilometres north-west of the city of Val d’Or and is easily accessed by a rural road network connecting to a national highway a few kilometres east of the project site. The project area comprises 24 mineral claims totalling 884 hectares. No new activities were undertaken at the project during the period. Tansim Lithium Project 132 claims, 7,622ha The Tansim Lithium Project is situated 82 kilometres south-west of the Authier Lithium Project. Tansim comprises 132 mineral claims spanning 7,622 hectares and is prospective for lithium, tantalum, and beryllium. Mineralisation 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. No work was carried out at Tansim during the period as activities focused on NAL and Moblan however, 54 claims were relinquished following an evaluation and prioritisation of prospectivity. This project supports the broader strategy of establishing a significant lithium hub in the region and Sayona is focused on ensuring the project generates maximum benefits for all local stakeholders, including First Nations people, together with minimising any environmental impacts. Vallée Lithium Project 28 claims, 1,247ha The Vallée Lithium Project is located in Abitibi, Québec, near the township of La Corne. The project is situated within the heart of the southern portion of the Abitibi Greenstone Belt, approximately 60 kilometres north of Val-d’Or and contiguous and adjacent to the NAL mine. NAL achieved the required spend in FY24 to earn an initial 25% interest in the Vallée Joint Venture. However, the drilling results did not support progression to the Second Option of the earn-in agreement. As such, NAL retains its current 25% interest in the Vallée Joint Venture and will evaluate other opportunities within the joint venture tenements as they are identified. No new activities were undertaken at the project during the period. Pontiac Claims 257 claims, 14,560ha Sayona’s Pontiac Claims are situated 15–60 kilometres from the Tansim Lithium Project. Pontiac comprises 257 mineral claims spanning 14,560 hectares and is prospective for lithium, tantalum, caesium and beryllium. The Pontiac prospect lies along the southeastern edge of the Superior Craton, featuring metasedimentary and metavolcanic rocks of the late Archean eon. The sites were chosen for their geological similarity to the drill ready target of Viau-Dallaire at the Tansim Project. As such, the Pontiac claims have a strong exploration potential for lithium-bearing pegmatites. Following an evaluation and prioritisation of prospectivity, 1,027 claims were relinquished during the year to focus on the highest priority targets and reduce expenditure commitments. Regional Exploration Projects (Québec) Sayona Annual Report 2025 22

Lac Albert Lithium Project 121 claims, 6,592ha The Lac Albert Lithium Project, another potential asset in Sayona’s Québec portfolio, is located 3.5 kilometres west of the Moblan Lithium Project, in the same proven lithium mining province, the new claims span 6,592 hectares and will be assessed for lithium pegmatite occurrences. These claims are separate to the Moblan Lithium Project. Initial exploration efforts have focused on mapping and sampling to identify target areas for drilling. This project is part of Sayona’s strategy to diversify its resource base and support long-term growth. During the year prospecting activities were undertaken, however no results of significance were returned. Troilus Claims 1,824 claims, 98,423ha Acquired in November 2022, the Troilus Claims near the Moblan Lithium Project cover 1,824 claims spanning 984 square kilometres. These claims offer potential for significant lithium mineralisation, with possible extensions to Moblan mineralisation. The strategic location and size of this package make it a valuable addition to Sayona’s exploration portfolio, contributing to the company’s growth strategy in the Eeyou Istchee James Bay region. During the year rock and soil samples were collected in conjunction with geological reconnaissance and geophysical surveys. A number of promising assay results were returned and will be further investigated in future work. This portfolio of projects supports the broader strategy of establishing a significant lithium hub in the region and Sayona is focused on ensuring the portfolio generates maximum benefits for all local stakeholders, including First Nations people, together with minimising any environmental impacts.

FY25 in Review During the year Sayona continued to advance its portfolio of early-stage lithium and gold projects in Western Australia through systematic exploration, joint venture collaboration and disciplined investment. The Western Australian assets offer exposure to discoveries within one of the world’s most prospective mining jurisdictions. In the Pilbara region the Company holds 100% of the lithium rights to seven tenements/applications covering 346 square kilometres. At the Tabba Tabba project, which is the most advanced, Sayona continued its drill programs which have provided valuable geochemical and geological data, enhancing the understanding of the tenement’s potential. Work is focused in the search for flat lying pegmatite systems, principally hosted along a six kilometre strike of the Western Gabbro Corridor. The Tabba Tabba project is directly south and along strike from Wildcat Resources’ (ASX: WC8) Tabba Tabba lithium deposit. Within the 597 square kilometres of tenure where Sayona has 100% of the gold rights, exploration is focused on intrusion hosted gold mineralisation in a style similar to Northern Star’s nearby Hemi gold deposit. The Morella Lithium Joint Venture remains a material component of Sayona’s Western Australian lithium strategy and is managed by Morella Corporation Limited (ASX: 1MC). The Pilbara JV area comprises six tenements covering 356 square kilometres. Projects include the advanced Mallina area which is host to spodumene pegmatite, as well as strategically placed tenure in the Tabba Tabba area. The JV also includes two tenements in the South Murchison covering 48 square kilometres where first drilling at Mt Edon has identified rubidium-bearing pegmatites. Sayona intends to continue contributing its share of JV expenditures to maintain its 49% equity in this key JV collaboration. In the Pilbara region the Company holds 100% of the lithium rights to seven tenements/applications covering 346 square kilometres. At the Tabba Tabba project, which is the most advanced, Sayona continued its drill programs which have provided valuable geochemical and geological data, enhancing the understanding of the tenement’s potential. Western Australia Sayona Annual Report 2025 26

Exploration Activities Tabba Tabba Drilling has included three phases of reverse circulation (RC) drilling in the northern portion of the tenement area, with 9 holes for 2,873 metres completed. Holes were sighted on extensions to the Tabba Tabba deposit stratigraphy and gravity features indicative of the target gabbro host. Additionally, a 76 hole, 1,410 metre air core drill programme has been completed over parts of the central and eastern tenement areas. Although drilling to date has not identified material assay results, encouraging geochemistry and geological data have led to a large number of targets for future drilling being identified along the Western Gabbro Corridor. These include potential extensions to the Luke and Leia pegmatite systems immediately south of the Wildcat lithium resource. Fieldwork has also enhanced targeting of prospective gabbro host units and structural settings which facilitate emplacement of flat lying spodumene pegmatite. Newly identified pegmatites along the central western flank of the Western Gabbro trend will be a focus for future fieldwork. 100%-Owned Lithium and Gold Projects Regional geochemical sampling, mapping, and reconnaissance was carried out to advance drill targeting at the Red Rock and Mt Dove project areas. A total of 1,374 samples, assayed using the low level CSIRO ultrafine+ technique has advanced planning for the drill testing of targets. Morella Lithium Joint Venture At the Mt Edon JV project RC drilling has intersected significant pegmatite hosted rubidium mineralisation. Assays up to 0.59% Rb2O were returned with elevated lithium levels of up to 0.63% Li2O. Broad zones of pegmatite, including stacked systems, were identified in 15 of the 17 RC holes. At the Sophie prospect, which extends ~600 metres in strike extent, pegmatite intercepts up to 112m wide were recorded, including rubidium mineralisation across a 74 metre zone. To help guide project development, a formal research agreement has been entered into with Edith Cowan University to characterise the Mt Edon rubidium mineralisation. The Stage 1 study will use drill samples to identify optimal steps in the direct extraction and purification of a rubidium end product. Further development drilling is planned at Mt Edon with potential to lead to a maiden mineral resource. Exploration work in other JV areas included regional reconnaissance sampling and follow up of promising soil geochemical results at the West Wodgina lease. Five new targets will be assessed to identify potential areas for maiden drill testing. At Mallina, a ground gravity geophysical survey commenced in July 2025 to help in the search for gabbro hosted spodumene pegmatite systems. Further development drilling is planned at Mt Edon with potential to lead to a maiden mineral resource. Sayona Annual Report 2025 27

HR Systems Transformation As part of our efforts to strengthen organisational scalability and prepare for post-merger integration, Sayona implemented the Dayforce Human Capital Management (HCM) platform during FY25. This cloud-based system streamlines key HR operations such as time and attendance tracking, payroll, and manager self-service. By modernising these processes, we have enhanced data accuracy, improved regulatory compliance, and equipped leaders with real-time workforce insights — laying the foundation for a more agile and integrated organisation. Attracting and Retaining Talent In a highly competitive labour market, particularly in Abitibi-Témiscamingue, talent attraction and retention remain a key focus. Throughout FY25, we prioritised local recruitment and deepened our engagement with local communities near our operations. The mining sector continues to face labour shortages, skills gaps, and high turnover rates in remote regions. These challenges are particularly acute in Québec, where competition for qualified talent remains strong. To address these risks, Sayona focused on reinforcing community ties and promoting long-term employee engagement and retention. As operations ramped up, these efforts contributed to 99 hires in FY25, representing 44% of our total employee base. At our North American Lithium operation, 75% of employees were recruited from the Abitibi-Témiscamingue region. Despite sector-wide pressures, our voluntary turnover rate stood at 17%, reflecting both the realities of the current labour market and the need for sustained retention strategies. Employee Development Investing in our people is essential to ensuring long-term operational excellence. Sayona is committed to building internal capability through continuous learning and development. Employees received a total of 3,251 training hours, representing 3% of total payroll invested in development initiatives. Internal mobility remains a priority, with 30 employees promoted to new roles in FY25. These results demonstrate our commitment to building internal talent pipelines and preparing the next generation of leaders in support of our long-term growth strategy. Diversity, Equity, and Inclusion Diversity is a core strength at Sayona. In FY25, visible minorities represented 7% of our workforce, and Indigenous employees 2%. We are committed to increasing representation across all levels of the organisation. We also advanced our culture of integrity and inclusion through key initiatives, including: • Mandatory governance training on our Code of Conduct, which was delivered to all employees. • Behaviours in the workplace training program, rolled out to all supervisors and managers. To support the onboarding of new employees, especially those newly arrived in the region, we established a Cultural Integration Committee. Through monthly inclusion themes shared in health and safety meetings and a mentorship program that pairs newcomers with experienced colleagues, the committee fosters connection and belonging. Our periodic team step challenge, “Sayona en marche”, promotes wellness, friendly competition, and cross-functional engagement. Now in its second year, the initiative includes participants from both our corporate and operational teams in Québec, as well as colleagues from our Australian head office. It fosters a strong sense of connection across the broader organisation. In 2025, the program was nominated by the Québec Mining Association for its contribution to innovative human resources practices, highlighting our commitment to employee wellbeing and an inclusive workplace culture. Culture and Values Our organisational culture is grounded in the core values of integrity, respect and excellence. These principles guide how we collaborate, make decisions, and engage with our employees, partners, and communities. To bring these values to life, we’ve created platforms for open dialogue and collaboration. The Collaboration Committee, composed of employees and management, meets monthly to address opportunities for improvement and strengthen mutual understanding. By promoting inclusive leadership behaviours and building trust at every level, we are creating a positive, high-performing environment where people feel valued and empowered. Diversity is a core strength at Sayona... We are committed to increasing representation across all levels of the organisation. Sayona Annual Report 2025 30

Sustainability FY25 Health and Safety Performance Fiscal year 2025 was an improved year for employee health and safety performance. Focused on improved systems and rigorous operational processes, Sayona reduced the rate of incidents involving injuries, while also having two remote drilling campaigns and a significant increase in spodumene concentrate production. The NAL site had its longest triple-zero period in history (87 days — total recordable injury free), enabling it to significantly reduce TRIFR. We also saw a significant reduction in the number of Lost Time Injuries (LTIs) sustained during the course of FY25, which point to a reduction in severity of incident type. During FY26 we are striving to build upon the improvements and gains made during FY25 with continued safety performance focusing on leading indicators, standardisation of processes and practices and further engagement at all levels. Fiscal year 2025 2024 Medical aid 5 6 Modified duty 13 18 Lost time injury 8 18 TRIFR per 200,000 work hours 4.16 5.71 TRIFR per million work hours 20.79 28.56 Total hours worked (million) 1.25 1.47 At Sayona, we believe that our Sustainability efforts are ensuring that needs of the present are met without compromising the opportunity of a prosperous future. We approach this with a commitment to be stewards of the environment, good neighbours in our community, and respectful of the resources we use. Our use of hydro-power, our many efforts in water conservation and waste reduction are evidence of this in our daily operations. Engagement with our communities and stakeholders are vital to foster economic development and social well-being for the community and our employees. Integrating sustainability into our business, allows us to create long-term value and ensure a prosperous legacy for years to come. Sayona Annual Report 2025 32

Total Recordable Injuries FY24 Lost time injury Modified duty Medical aid 18 18 6 Total Recordable Injuries FY25 Lost time injury Modified duty Medical aid 8 13 5 Health and Safety Management System At Sayona, the Health and Safety (HS) of our employees is paramount in everything that we do. The HS Management System ensures that we identify, assess, control risks or mitigate the consequences of them. This applies to everyone at Sayona. The focus in FY26 is to continue our efforts in implementing HS standards and policies for Sayona with a focus on preventative actions to identify risks and hazards. We continue to implement our management systems to ensure that critical risk management is embedded in every process at the site. Health and Safety Joint Committee At NAL, the HS joint committee has been established to provide the opportunity to employees and management team to discuss risks and their controls. During FY25 risks that were analysed by the committee with mitigation recommendations include: • Working in confined spaces • Lockout/Tagout • Dust control. Emergency Response Team In 2025 we completed the full implementation our emergency plans including three simulations of events that would trigger the plan. Two simulations were carried out in connection with environmental events and one in connection with a rescue. These simulations revealed areas for improvement but clearly demonstrated the ability of the NAL teams to manage major events. In FY26, we will continue to enhance and develop the effectiveness of the team with continuous training and simulations. The “ici” Program In accordance with the “ici” program, Sayona encourages workers and supervisors throughout the year to show initiative by reporting potential hazards and creating a positive impact with the corrective actions taken. Every month, efforts were recognised with various forms as a means of celebrating and reinforcing positive behaviours. In FY26, we will continue to enhance and develop the effectiveness of the team with continuous training and simulations. Sayona Annual Report 2025 33

Environmental Governance Climate Change and Carbon Intensity In 2025, mine site activities generated 29,937 tonnes of CO2 equivalent (CO2e), reported in line with regulatory requirements to provincial government authorities on an annual basis. These figures cover Scope 1 and Scope 2 emissions. Spodumene concentrate production increased from 155,822 tonnes in 2024 to 204,858 tonnes in 2025 (+31%), while total CO2e emissions decreased by 14% over the same period. The reduction in greenhouse gas emissions, despite higher production levels, was primarily driven by: • Consolidation of mining infrastructure, which significantly reduced waste rock transport distances; and • Improved management of fossil fuel-powered equipment. When converted to lithium carbonate equivalent (LCE), the 2025 spodumene production equates to 22,765 tonnes of LCE. This resulted in a carbon intensity of 1.32 t CO2e per tonne of LCE in 2025, down from 1.97 t CO2e per tonne in 2024 (a 33% reduction). Unit 2025 2024 Variance y/y Spodumene concentrate produced dry metric tonnes 204,858 155,822 +31% Total of CO2e (Scope 1 & 2 only) tonnes 29,937 35,511 -14% Lithium carbonate equivalent (LCE)(1) tonnes 22,765 17,856 +28% Intensity CO2e / t of LCE 1.32 1.99 -33% (1) Based on an unaudited internal study. Sayona is currently conducting a life cycle assessment that will consider the entire process of spodumene concentrate production from primary ore extraction, to international delivery of spodumene concentrate. This life cycle assessment is being conducted by an external specialist. The study should be complete in calendar year 2025. By sourcing its electricity from renewable sources, primarily hydroelectric and wind power, the NAL site has a distinct advantage in relation to carbon intensity. Sayona works continuously to reduce the carbon footprint associated with its activities, while respecting local communities and biodiversity. Sayona’s commitment to environmental responsibility is evident in our performance. Sayona is currently conducting a life cycle assessment that will consider the entire process of spodumene concentrate production from primary ore extraction, to international delivery of spodumene concentrate. Sayona Annual Report 2025 34

Biodiversity Management Sayona is committed to preserving biodiversity as it undertakes its mining operations and has established a platform for recording wildlife observations on site. This platform helps monitor the presence of wildlife within operational areas and supports proactive management practices. In addition, Sayona conducted awareness programs to promote biodiversity conservation among site personnel. To achieve a net positive impact on fish habitats, Sayona has implemented compensation projects in line with Canadian environmental legislation. The first project, completed in 2025, involved replacing a culvert with a bridge within the project area. This upgrade increased fish habitat and significantly improved fish passage in the region. A second fish habitat compensation project, planned for 2026, is expected to further enhance biodiversity outcomes and strengthen Sayona’s contribution to the ecological health of the mine’s host region. Residual Materials Management — the Circular Economy Following the restart of operations, a significant quantity of materials, equipment, and other items were placed in storage for potential reuse. Over time, however, these items remained unused and occupied valuable space. To address this, the surface maintenance team reviewed and sorted the stored materials. Items that could not be reused but still held value were made available for purchase, while others were offered through a silent auction. Employees were given the opportunity to acquire items for a symbolic price, resulting in more than C$5,500 being raised and donated to a local charity. This initiative also diverted over 15 tonnes of materials from landfill. A similar approach was applied to surplus office supplies, generating an additional C$1,100, which was again donated to a charitable organisation. Mine Closure and Rehabilitation During the financial year, Sayona received government approval for its mine closure plan. This plan is required to be reviewed every five years or whenever significant operational changes occur. As NAL’s operations have only recently restarted, no progressive rehabilitation activities have been undertaken to date. Tailings Management Operations at TSF1 proceeded in line with deposition plans, with minor operational adjustments implemented without impacting plant performance. The southern wall was raised by 1.75 metres, providing the necessary tailings and water management capacity to enable the safe operation of the facility. Planning for the commissioning of a second tailings storage facility (TSF2) progressed during the year. Preliminary engineering work has been completed, and Sayona is currently evaluating alternative technologies for either dry or wet deposition through a variant analysis. A final decision on the preferred approach is expected in the course of calendar year 2025. Water Management The NAL site is located in a region with abundant water resources. As a result, mining and spodumene concentration activities generate a surplus of water, primarily sourced from the dewatering of the open pit. During the financial year 994,788 cubic metres of water were discharged into the environment via a series of retention basins, following stringent analysis and assessment to ensure compliance with environmental standards. Waste Management Industrial and exploration operations generated 1,411 tonnes of residual and hazardous waste, all of which were recovered and treated in accordance with local regulatory requirements. Additionally, 480 tonnes of contaminated soil were recovered and treated at a government-authorised facility. Sayona Annual Report 2025 35

Social Responsibility Building Strong Relationships with First Nations and Host Communities At Sayona, we believe that a key part of our success is rooted in the strength of our relationships with both First Nations and our host communities. We are committed to fostering respectful, transparent, and lasting partnerships built on mutual trust and understanding. Over the past year, we have engaged with First Nations as part of our commitment to consultation and collaboration. These discussions have focused on various projects, including drilling campaigns and proposed amendments to authorisations related to our operations at the North American Lithium (NAL) site. These consultations are an essential part of our process, ensuring that Indigenous voices are heard and taken into consideration in our decision-making. More broadly, our approach to community relations is guided by a spirit of active engagement.

Transparency and accountability remain cornerstones of our engagement strategy. Through regular updates, community meetings, and feedback mechanisms, we strive to ensure that our presence continues to bring lasting value to the regions we operate in. Sayona Monitoring Committee Updates Over the past year, the NAL Monitoring Committee has continued its important work of engaging with key stakeholders through quarterly meetings. The objectives of this committee are to discuss the progress of projects and operations at our active mine, North American Lithium; to maintain open and transparent dialogue with committee members; to promote the sharing of information and local knowledge, as well as insights from local stakeholders and external experts; and to share our operational, environmental, and social results each quarter in a transparent manner. Key Points Include: • Corporate Developments: The merger with Piedmont Lithium will create a globally significant hard rock lithium producer under the name Elevra Lithium. • Environmental Stewardship: The committee reviewed environmental monitoring, including water management at the North American Lithium site. A fish habitat offset project was introduced, and other topics included wildlife protection and ecological initiatives. • Operations and Performance: Sayona continues to show strong operational performance, with a 31% increase in FY25 concentrate production. A significant safety milestone was reached with 87 days without a recordable incident. • Workforce and Regional Impact: The company continues to focus on local employment, especially in the Abitibi-Témiscamingue region. Updates were provided on human resources and infrastructure planning. • Community Engagement and Projects: Several community-related projects were discussed, including the reuse of mine tailings and progress on the La Corne site. The committee also discussed local concerns like groundwater protection and infrastructure improvements. The Monitoring Committee remains integral in guiding NAL’s responsible mining practices, environmental efforts, and community partnerships. At Sayona, we believe that a key part of our success is rooted in the strength of our relationships with both First Nations and our host communities. We are committed to fostering respectful, transparent, and lasting partnerships built on mutual trust and understanding. Sayona Annual Report 2025 36

Sayona Annual Report 2025 37

Risk Management Sayona’s risk management processes and internal control systems are based on the principles of the ISO 31000 Standard for Risk Management adopted by ASX, which contributes to ensuring that risk and assurance activities are continually adding value to the business activities of Sayona and supporting the delivery of its projects. Sayona’s Board is responsible for overseeing risk and has assigned accountabilities and responsibilities for risk management to the Audit and Risk Committee (ARC), the Managing Director and executive management. Sayona’s risk management processes and internal control systems apply across Sayona’s entire business, including all of its operations and projects. The risk focus is on material issues that could prevent the delivery of Sayona’s objectives (including, without limitation, safety, sustainability, and exposure to environmental and climate change risks). The focus for FY25 was to enhance and expand the effectiveness of the Group’s risk management program. This was done with the adoption of a Risk Management Policy, Risk Appetite Statement, and Risk Management Standard. A comprehensive risk assessment was conducted to evaluate the material issues. Risk Materiality The Board defines the term ‘materiality’ recognising that financial measures criteria in its determination are complemented with non-financial criteria that are important to the achievement of corporate objectives such as health, safety and environmental impacts, and the reputation of Sayona. The Board’s risk appetite utilises the materiality definition. This means that, in practice, every ‘material’ risk must be referred to the ARC for its review and acceptance. The ARC assumes delegated authority on behalf of the Board to review and accept ‘material’ risks reported to it by the Managing Director and executive management. The Company’s Nomination and Remuneration Committee also oversees risks relevant to the areas it is responsible for. The following section describes (in no order of significance) the material risks that have been identified and are being managed for the Company to deliver on its objectives. It is not intended to be all encompassing, nor is any of the information intended to be taken as a statement of fact. These risks can be affected by a variety of factors, which can, in turn, impact the Company’s performance. Sayona recognises that risk is an inherent part of its business. Effectively identifying and managing risk is critical to Sayona’s success. Sayona Annual Report 2025 38

Risk Description of Risk Mitigating Actions 1 Safety and Sustainability Operational Safety Material safety event within the organisation or failure to address well-being matters. 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. Sayona’s HSE standards have been developed and rolled out across the organisation, to its operations and development projects, to establish a consistent good practice approach to HSE management and in compliance with local laws and regulations. In addition, overall wellness has been incorporated into these programs to ensure balance of overall safety. Additionally, risk assessments are incorporated in operational aspects to provide a proactive approach to safety and wellness. Climate Change Risk Physical and transitional factors that could impact operations, supply chain, stakeholder engagement, or regulatory compliance. Severe weather events, increased frequency of wild fires and the other challenges posed by climate change are inherently uncertain and have the potential to adversely affect Sayona’s operations, supply chain infrastructure and financial performance. Sayona evaluates future climate scenarios in project planning and operations. There is ongoing monitoring of climate-related risks; with the implementation of decarbonisation initiatives such as electric trucks. Social and Environment Failure to build positive relationships with local communities, regulators and local government leading to opposition, protests, or legal challenges. Material environmental event with potential impact to biodiversity, air, land and water resources or failure to comply with regulations. 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. We actively engage with all our stakeholders on a regular basis to better understand and address their individual needs. We work with local communities to develop meaningful relationships and regularly carry out social impact assessment on work programs. We undertake environmental monitoring programs and studies to better understand and mitigate our impact on the environment; while also conducting internal audits. Human Rights Occurrence of forced labour, debt bondage, child labour, recruitment and labour broker exploitation, wage and employment exploitation, unsafe and inhumane working conditions and restrictions on worker rights and freedom by our suppliers or contractors. Sayona is subject to extensive laws and regulations regarding human rights in all regions that we work and operate. We expect that our suppliers and contractors follow those same laws and regulations while we also develop contracts that detail our expectation; including our Modern Slavery Statement. Clauses within our contracts further detail these requirements. Sayona Annual Report 2025 39

Risk Description of Risk Mitigating Actions 2 Operational and Project Risks Operational Performance Inability to deliver safe, stable, and predictable operational performance and quality product to customers. The performance of North American Lithium continues to target improvements and/or consistency of the quality of product and the ability to meet production targets and tonnages, cost of production and return on capital. There is a collaborative effort that must be achieved to meet and maintain operational excellence. The experienced and dedicated staff, tools and resources, and the knowledge of contractors are paramount. If there is an incident of any type, a diverse incident management team comes together to determine the root cause while implementing corrective actions. Major External Events or Natural Disasters Damage to site infrastructure or offsite transport/energy related infrastructure, disruption to services and suppliers and access to site by employees. Sayona’s operations 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. Contingencies are in place to ensure operational continuity during any route closure/disruption periods. Stocks of critical reagents are maintained to ensure operating continuity. Project Execution The Sayona project portfolio fails to deliver NPV expectations (Cost, Schedule, Revenue). 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.). Sayona is focused on de-risking the development of these projects by dedicating experienced professionals focused solely to manage these projects, by utilising proven technology based on Sayona’s existing operational expertise and by staging development to smooth capital expenditure and reduce market risk. Exploration Failure of the exploration program to result in the discovery of a mineral deposit, an increase in the current mineral resource, or the conversion of any of the mineral resources to ore reserves. Sayona’s experienced geological team develops detailed plans that take all factors into consideration to ensure that they are provided with the best details to define and determine the scale, quantity and quality of potential resources. The execution of their plans are controlled well by managing the program and the contractors that support the work. Staffing and Key Management Personnel Failure to effectively attract, train and retain employees with the required skillset to implement business strategy in each area where we operate. 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 has recently reviewed its approach to retaining key personnel and attracting talent. This includes employee development programs, ensuring a diverse and inclusive work environment and a focus on hiring talent from local communities. The Company provides competitive and fair total remuneration packages, a safe workplace, and a commitment to strong corporate values. Sayona Annual Report 2025 40

Risk Description of Risk Mitigating Actions 3 Strategic and Financial Risks Commodity Price Risk Fluctuation of the market Lithium price versus basis for revenue forecasting. 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. While the lithium market continues to be volatile, Sayona has endeavoured to manage these risks by establishing operations to be able to operate through a low-price environment and focusing on cost reduction and efficiency opportunities. Market Changes in the Lithium Industry The demand for lithium is dependent on the use of lithium in end markets and the general economic conditions. 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. The Company has a clear understanding of market trends and navigates risks concerning market changes. Macro Risk Global external factors including macro-economic risk affecting profitability and business continuity. 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. While Sayona has limited direct controls over these issues, continued oversight is essential to ensuring the ongoing profitability of the operations and projects. Geopolitical Risk Rivalries between geopolitical powers resulting in a fracture of multilateral relations or conflicts with global consequences. Global and local conflicts, including the threat of increased tariffs, tensions between China and Taiwan and the war in Ukraine, could adversely impact Sayona’s operations, financial performance and financial position. While Sayona has limited controls over these external issues, it continuously evaluates threats and risks associated with carrying out business activities with organisations that have a large exposure or concentration in areas with high geopolitical risks to reduce/avoid such risks.

Risk Description of Risk Mitigating Actions 3 Strategic and Financial Risks (continued) Political Risk Changes in political, regulatory, or fiscal frameworks impacting Sayona’s business. 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. Continuous engagement between key management and government at both national and provincial levels actively mitigate this risk. Ongoing engagement will ensure these relationships continue. Liquidity and Funding Availability of debt or capital on terms acceptable to the Company. Sayona’s operations and development plans may require additional funding or capital for future activities. 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. Fraud, Corruption or Misconduct Actual or alleged fraudulent or corrupt actions involving Company activities or assets, customers, or suppliers. Contravention of Sayona’s Code of Conduct creating reputational and other issues. Sayona’s reputation, business and financial performance may be materially and adversely impacted by fraud or violations of anti-bribery and anti-corruption laws. Group wide policies have been developed to address anti-corruption and fraud. In addition, Sayona’s Code of Conduct defines the required business standards and ethics for the entire workforce (staff, employees, contractors). Contravention of these policies can result in disciplinary action or dismissal. Cybersecurity Failure to prevent cyber attacks, data breaches, or the loss of sensitive corporate or employee data. Cybersecurity events can have an operational, financial, legal, reputational or regulatory impact. It is important to have the appropriate protections in place to minimise the potential risks that exist. Sayona has implemented cybersecurity programs, management tools, and detailed access controls. Further evaluations are being conducted to determine other best of class options. Legal Disputes Unsuccessful defence of litigation/disputes with other parties. Sayona acknowledges that as a public company there is the potential risk for litigation or disputes with various parties; which could impact operations, financial performance of financial position. Sayona has an experienced legal team with accessible external resources to ensure business is conducted ethically and aligns with the Code of Conduct, which defines the required business standards and ethics for the entire workforce (staff, employees, contractors). There are multiple controls and checks and balances to conduct business of a collaborative manner with internal and external stakeholders. Reporting Errors Inadvertent/Unintentional error in reports that are submitted to various regulatory bodies (i.e. financial, environmental). Sayona’s professionals work diligently to ensure that all reported data is accurate and true; including verifications at different levels internal and external to the organisation. There are times when errors do inadvertently or unintentionally occur. Once realised, all necessary actions are taken to correct the information as timely as possible. Sayona Annual Report 2025 42

As such, subject to satisfaction of the remaining conditions, completion of the merger is scheduled to take place on 30 August 2025. Following completion of the merger, Piedmont Lithium Inc. will become a wholly owned subsidiary of Sayona, with Sayona being the surviving entity with a primary listing on the ASX and a secondary listing on the Nasdaq. Capital Management On 28 November 2024, the Group completed a $40 million fully underwritten placement to institutional, professional and sophisticated investors, resulting in the issuance of 1,250,000,000 fully paid ordinary shares at an issue price of $0.032 per share for aggregate gross proceeds of $40.0 million.

Significant Events after Reporting Date On 18 November 2024, Sayona Mining Limited, Shock MergeCo Inc., a wholly owned subsidiary of Sayona (“Merger Sub”), and Piedmont Lithium Inc. entered into a Merger Agreement to combine Sayona and Piedmont. The merger was approved by Sayona shareholders at the Company’s Extraordinary General Meeting on 31 July 2025. Piedmont stockholders subsequently approved the merger at their Special Meeting on 23 August 2025 (Australian time). As such, subject to satisfaction of the remaining conditions, completion of the merger is scheduled to take place on 30 August 2025. Following completion of the merger, Piedmont Lithium Inc. will become a wholly owned subsidiary of Sayona, with Sayona being the surviving entity with a primary listing on the ASX and a secondary listing on the Nasdaq. On 19 November 2024, the Group entered into a Subscription Agreement with Resource Capital Fund VIII L.P. (RCF) to raise approximately $69 million (before costs) through the issue of 2,156,250,000 ordinary shares in Sayona Mining Limited at an issue price of $0.0320 per ordinary share, subject to completion of the proposed merger with Piedmont Lithium Inc. (“Conditional Placement”). On 31 July 2025, Sayona shareholders approved the Conditional Placement to RCF.

As part of the extension, RCF agreed to subscribe to a further 1,200,000,000 options (“New Options”) to be issued in two tranches: • The first tranche of options to be issued shall be such number of options that results in RCF holding a 9.99 per cent interest in the issued share capital of the Company (Tranche 1 Options); and • Subject to obtaining all applicable regulatory approvals, the second tranche of options to be issued shall be such number of options that is 1,200,000,000 less the Tranche 1 Options (Tranche 2 Options). The exercise price of the New Options is $0.0320, a 14 per cent premium to the closing share price on 11 August 2025 and the same price as the issue price under the Conditional Placement, and within the Company’s existing placement capacity under ASX Listing Rule 7.1. If all New Options are exercised in full, the total value of the placement will be approximately $38 million. No other matters or circumstances have arisen since the end of the reporting period that have significantly affected or may significantly affect the operations, results of operations or state of affairs of the Group in subsequent periods.

Sayona is well positioned for a rebound in lithium prices. Further information about likely developments in the operations of the Group and the expected results of those operations in future financial years has not been included in this report because disclosure of the information would be likely to result in unreasonable prejudice to the Group. Environmental Regulation and Performance Sayona seeks to be compliant with all applicable environmental laws and regulations relevant to its operations. The Group’s operations are subject to environmental regulation under the law in Australia and Canada. The Directors monitor the Group’s compliance with environmental regulation under law in relation to its exploration, mining, and processing activities. The Group holds all necessary approvals to undertake mining, processing and construction activities at its North American Lithium operation. Technical studies prepared in relation to the restart of operations at NAL and development of Moblan provide Directors with information and technical details in relation to the environmental regulations as they apply to mining and manufacturing operations. In addition, the Authier Lithium Project is subject to review procedures under the BAPE (Bureau d’audiences publiques sur l’environnement) as the Group seeks permitting approval to develop and operate a new mine. The NAL expansion project will be evaluated by the relevant regulatory authorities as the Group seeks to obtain permits required to expand the existing NAL mine. The Moblan Lithium Project will be evaluated by the relevant regulatory authorities as the Group seeks to obtain permits required to develop a new mine. A robust management system is employed to support regulatory compliance obligations with respect to environmental performance management. Voluntary disclosures are provided to the relevant regulator when required, and external auditors can be utilised to support compliance management. The Directors are not aware of any material compliance breach arising during the year and up to the date of this report. Sayona Annual Report 2025 49

Letter from Chair of Nomination and Remuneration Committee Dear Shareholders, On behalf of the Board, I am pleased to present the Remuneration Report for Sayona Mining Limited for the financial year ended 30 June 2025. This Remuneration Report outlines the remuneration philosophy, policy and structures adopted to support Sayona’s operational performance and strategic growth, building on the foundation set in FY24. During the year, Sayona continued to strengthen its leadership team and governance framework in preparation for the Company’s next phase of growth. Notably, the Board welcomed the appointment of Ms Laurie Lefcourt as Non-Executive Director on 16 October 2024, and Mr Lucas Dow transitioned to the role of Managing Director and Chief Executive Officer on 3 July 2024, supported by a strong executive team. We look forward to the continued execution of Sayona’s strategy under Lucas’ leadership and the Board’s guidance. Our Year in Review Sayona delivered outstanding operational performance at our North American Lithium (NAL) operation during the 2025 financial year. NAL reached the upper end of its production guidance, delivering full year spodumene concentrate production of 204,858 dmt. Furthermore, the site achieved the highest quarterly output to date, the two strongest production months at the end of the year, a record single-day production, and the highest recovery rate in its history. These results reaffirm NAL’s position in the lithium industry and reflect the strength and dedication of our operational teams. Operating expenditure ended the year in line with guidance, reflecting the operational realities of the ramp-up phase and continued investment in long-term stability, including additional costs required to stabilise the crushing area as a result of design limitations identified during the construction phase. Cost optimisation remains a key focus as the site continues to mature. For FY25, our Total Recordable Injury Frequency Rate (TRIFR), reported on a 1,000,000 work-hour basis, stands at 20.8, down from 28.6 in FY24. This represents a 27.2 per cent year-over-year improvement in safety performance. While we remain focused on continuously strengthening our health and safety culture, this result demonstrates meaningful progress and reflects the ongoing commitment of our teams across the organisation. Significant environmental improvements were also implemented, reinforcing the Company’s ongoing commitment to sustainable and responsible operations. Sayona continued to advance its strategic objectives during FY25, with efforts focused on the merger between Piedmont and Sayona and completion of exploration drilling programs at Moblan and NAL to expand our existing resource base. Executive Remuneration In FY25, business performance was assessed against sustainability, operational performance, and financial performance measures. Sustainability measures were in line with target whilst operational and financial performance measures were slightly below target. As a result, the business outcome was assessed as 51.0 per cent. Individually, the performance of Executive KMP exceeded expectations on the back of significant efforts to advance the Company’s strategic objectives, particularly the merger between Piedmont and Sayona. As a result, the overall STI outcomes for Executive KMP range between 60.8 per cent and 65.7 per cent of maximum STI opportunity. Non-Executive Director Remuneration At the 2025 Extraordinary General Meeting, shareholders approved an increase in the aggregate amount of remuneration that may be paid to Sayona’s Non-Executive Directors from $900,000 to $1,250,000 per annum. This approved increase is subject to and conditional upon completion of the merger with Piedmont Lithium Inc. There was no increase in base fees for Non-Executive Directors in FY25 and following completion of the merger with Piedmont, there will be no increase in base fees for Non-Executive Directors for FY26. Following the establishment of the Audit and Risk Committee and Nomination and Remuneration Committee, the Board approved the payment of committee fees to remunerate Non-Executive Directors for the broad range and complexity of matters considered by each Committee. The following fees were effective from the date of appointment to each Committee: • Committee Chair fee of $25,000 per annum • Committee Member fee of $12,500 per annum We trust that the FY25 Remuneration Report provides clarity on the links between our strategic objectives, company performance and remuneration outcomes as well as shareholder value creation. We greatly appreciate your past engagement, and we welcome your feedback on the remuneration framework as we look to continue to improve the transparency of our reporting to shareholders.

3. Remuneration Framework The Board understands and accepts shareholder expectations that remuneration of executives and employees should be linked to balanced financial and non-financial performance outcomes, appropriately governed and aligned with delivery and execution of the Company’s strategy and supported by sustainable long-term value creation for shareholders. With these elements in mind, the Board undertook a comprehensive review and evaluation of the Company’s remuneration practices in FY24 to ensure that our remuneration framework remains contemporary and appropriate for the scale and evolution of the Company whilst also maintaining a fair and equitable approach to remuneration decisions. In determining the remuneration framework for the Group, the Board followed a robust process which included discussions and engagement with investors and proxy advisers, taking into account the needs of the business and evolving market and best practices. The Board also considered input and advice from independent external advisers. Remuneration Strategy The Board is responsible for ensuring that remuneration policies, practices and outcomes across the Group are effective for the purposes of attraction, retention and reward of talent, whilst also ensuring alignment with the interests of shareholders and delivery of the Company’s strategy and performance. The remuneration framework has been designed to support the Company’s vision to support the global decarbonisation drive by sustainably producing high quality lithium products and incorporates the values that guide our actions being integrity, respect and excellence. In setting our remuneration framework, the Board aims to ensure the outcomes of the framework recognise the overall value and contribution that each employee delivers to the Company. In doing so, the Board’s primary objective is ensuring the framework is designed to address the following key principles: • Attract, retain and reward employees to perform to the best of their abilities, competencies and skill sets; • Ensure remuneration outcomes are market-based and fairly reflect an employee’s skills and experience; • Ensure remuneration outcomes are directly and transparently linked to the Company’s strategy and performance, and reward executives and employees to deliver the long-term growth and success of the Company; • Ensure there is no discrimination or bias based on race, age, gender, religion, country of origin, sexual orientation, marital status, dependents, disability, social class or political views; • Ensure remuneration practices are fair, equitable, transparent and consistent and that positions with similar levels of responsibility within the Group gain access to similar rewards; and • Maintain compliance with all applicable laws and appropriate standards of governance. When structuring executive remuneration, the Board aims to ensure that: • Remuneration packages are competitive to attract, retain and reward talented executives; • Executives are remunerated with an appropriate mix of fixed and performance-based remuneration; • Executive remuneration is aligned with the interests of shareholders; • Fixed remuneration is fair and reasonable relative to applicable market practices, prevailing market conditions and the scale and evolution of the Company; • Performance-based remuneration is clearly defined through the achievement of realistic, predetermined goals which are directly linked to the Company’s short-term and long-term objectives, and which take into account the Company’s overall performance (i.e. financial and non-financial measures covering sustainability, operational and financial performance, and strategic initiatives); and • Total remuneration packages are designed to encourage and reward superior performance and aligned to the creation of long-term shareholder value. To ensure our remuneration framework is competitive and maintains the Company’s ability to attract and retain key talent, the Board endeavours to ensure fair, competitive and commensurate remuneration outcomes by benchmarking rewards levels in accordance with market practices and a clearly defined peer group of similar sized companies on the Australian Securities Exchange (ASX) and within the global mining industry. Sayona Annual Report 2025 57

Remuneration Framework Our remuneration framework is designed to provide a total remuneration package that is appropriately balanced between fixed and variable components, with an emphasis on long-term variable pay. The framework is designed to build a performance-based culture that supports the strategic objectives of the Company and aims to attract, retain and reward executives and employees by offering market-competitive remuneration outcomes. The framework proposes that remuneration packages are comprised of a mix of the following components: Description Purpose Fixed Remuneration Fixed Annual Remuneration • Fixed annual remuneration consists of a market-competitive base salary, statutory entitlements (i.e. pension or superannuation) and other fixed benefits as a guaranteed, fixed element of remuneration. • Other fixed benefits include healthcare, housing allowances, insurance, matched pension or superannuation, motor vehicle allowances, salary sacrifice arrangements, and signing bonuses. • Other fixed benefits are either aligned to Company policy or specific to individual roles. • To meet the basic expectations of the role and deliver satisfactory outcomes. • To assist with attraction and retention of talent by providing market-competitive remuneration outcomes based on company size, industry benchmarks, business complexity, individual role responsibility, and individual skills and experience. • To meet remuneration package expectations of specific jurisdictions or professions. Variable Performance Related Remuneration Short-Term Incentives (STI) • Annual incentive paid in a combination of cash and deferred equity rights. • Subject to achievement of short-term performance targets (i.e. typically 12 months) of both the Group and individual roles, which typically includes both financial and non-financial performance measures. • To reward employees to drive short-term performance for the Group by focusing efforts on key priorities. • To reward performance outside of the basic expectations of the role. • To assist with attraction and retention of talent. Long-Term Incentives (LTI) • Annual grant of equity rights (i.e. rights to receive fully paid ordinary shares in Sayona Mining Limited), subject to performance and service conditions. • Awards assessed over a three (3) year measurement period, with vesting to occur at the end of the measurement period. • Awards directly linked to Relative Total Shareholder Return. • To reward employees to drive the long-term growth and success of the Company. • To ensure remuneration outcomes are aligned with shareholder experience over the long-term. • To assist with attraction and retention of talent over the long-term. The remuneration structure for executives, including the relationship between each element of remuneration and Group performance, is set out on the following pages: Fixed Annual Remuneration Element Description Purpose Fixed annual remuneration (FAR) is designed to assist with attraction and retention of talent by providing market-competitive remuneration outcomes based on company size, industry benchmarks, business complexity, individual role responsibility, and individual skills and experience. Opportunity FAR is determined on appointment based on the individual’s role and reward grade within the business and includes base salary, statutory entitlements (i.e. pension or superannuation), and other benefits. Base salary is determined based on the individual’s role, skills, experience, and prevailing market conditions. Reviews Base salaries are reviewed annually. The Board determines any increases based on Group and individual performance, global economic conditions, role responsibilities, an assessment against relevant comparator groups, and internal relativities. Any increase in base salary is generally aligned with average base salary increases applying to the broader employee population unless there were significant changes to an individual’s role or responsibilities during the year. Such changes may include a promotion or increase in responsibility or where the executive’s base salary is significantly below prevailing market levels. Benchmarking is undertaken periodically to ensure rewards levels remain aligned with market practices. Sayona Annual Report 2025 58

Short-Term Incentives Element Description Purpose The STI plan is designed to reward executives for delivery of annual performance goals set by the Board over a 12-month period. Opportunity The STI opportunity is determined by the individual’s role and reward grade within the business based on a percentage of base salary. STI payments are awarded to executives annually based on the achievement of annual performance goals above a minimum threshold for a range of performance objectives, including both Business KPIs (Business Outcome) and Individual KPIs (Individual Outcome), with 50 per cent of the award paid in cash and 50 per cent delivered in equity rights to receive fully paid ordinary shares in Sayona Mining Limited. The equity rights are deferred for 12 months and remain subject to continued service with the Group. Target and Maximum Opportunity The STI opportunity for Executive KMP is: • Managing Director and Chief Executive Officer — target opportunity of 70 per cent of base salary, with a maximum opportunity of 105 per cent of base salary for the achievement of stretch outcomes; • President and Chief Operating Officer, Canada — target opportunity of 60 per cent of base salary, with a maximum opportunity of 90 per cent of base salary for the achievement of stretch outcomes; • Chief Financial Officer — target opportunity of 60 per cent of base salary, with a maximum opportunity of 90 per cent of base salary for the achievement of stretch outcomes. The maximum STI opportunity represents 150 per cent of the individual’s target STI opportunity for the achievement of stretch outcomes. A minimum performance threshold of 50 per cent of target must be achieved for individuals to receive an STI award. Performance Measures The STI award is an at-risk component of the individual’s total remuneration which is contingent upon the achievement of predetermined performance measures relating to Business KPIs (Business Outcome) and Individual KPIs (Individual Outcome). Each year, targets are set by the Board based on metrics that are measurable and transparent, and which are designed to reward executives on the achievement of outcomes that deliver value for shareholders. In FY25, the Business Outcome of the STI award is determined by reference to the following financial and non-financial measures, as set out on page 64 of the report: • Sustainability — 25 per cent weighting; • Operational and Financial Performance — 75 per cent weighting. The Individual Outcome of the STI award is based on a system of continuous performance feedback to drive executive performance, which is regularly reviewed by the Board throughout the financial year against defined KPIs. A final performance assessment for each individual occurs annually following the completion of the financial year. Executives are assessed on their contribution to the achievement of Business KPIs (Business Outcome) and Individual KPIs (Individual Outcome). The overall STI outcome is calculated based on the following weightings: • Managing Director and Chief Executive Officer — 80 per cent weighting to Business Outcome, 20 per cent weighting to Individual Outcome; • Other Executive KMP — 70 per cent weighting to Business Outcome, 30 per cent weighting to Individual Outcome. Measurement Period The STI plan is measured over a 12-month period from 1 July to 30 June each year. Delivery Method The STI award is delivered as follows: • 50 per cent to be paid in cash in September each year; • 50 per cent to be delivered in equity rights (to be granted in November each year following the Annual General Meeting), with vesting to occur 12 months after the cash component is paid and subject to a service condition to remain employed at the vesting date. Cessation of Employment If an individual’s employment is terminated before the end of the financial year, the individual may or may not receive a pro-rata STI payment, depending on the circumstances of the cessation of employment. Outstanding unvested equity rights awarded under the STI plan will also be reviewed by the Board and may or may not vest, depending on the circumstances of the cessation of employment. Board Discretion The payment of STI awards is subject to Board approval. The Board has the discretion to adjust remuneration outcomes higher or lower to prevent any inappropriate reward outcomes, including reducing (down to zero, if appropriate) any STI award. Reviews The STI opportunity is benchmarked to market and reviewed by the Board annually. Malus and Clawback The Board may, at its discretion, reduce the number of shares to be received on vesting of an award, or in certain circumstances clawback all vested and unvested STI awards from a participant for a period of two years after the vesting or payment of a cash or equity award. Sayona Annual Report 2025 59

Long-Term Incentives Element Description Purpose The LTI plan is designed to reward executives to drive long-term performance by focusing participants on the creation of long-term shareholder value and delivery of strategic objectives set by the Board. Opportunity The LTI opportunity is determined by the individual’s role and reward grade within the business based on a percentage of base salary and is awarded by the offer of an equivalent number of rights to receive fully paid ordinary shares in Sayona Mining Limited. The equity rights remain subject to meeting specific performance and service conditions over a three (3) year measurement period. The maximum LTI opportunity for Executive KMP is: • Managing Director and Chief Executive Officer – 110 per cent of base salary; • Other Executive KMP – 85 per cent of base salary. As the rights are an element of remuneration, no amount is payable by executives to be allocated the rights. If the rights vest, no consideration or exercise price is payable for the allocation of shares upon exercise. Grant Date Equity rights are anticipated to be granted in November each year following the Annual General Meeting based on the Volume Weighted Average Price (VWAP) of ordinary fully paid shares in Sayona Mining Limited traded on the ASX over the ten (10) trading days following the announcement of the annual financial results. Service Condition Equity rights remain subject to continued service with the Group for the duration of the measurement period. Performance Measures The LTI award is determined by reference to the following performance measure: • Relative Total Shareholder Return (TSR) — 100 per cent of the LTI award is based on a percentile ranking of the Company’s TSR relative to the TSR of a comparator group of similar sized companies on the ASX and within the global mining industry over the same three (3) year measurement period, with vesting as follows: - Below 50th percentile – 0 per cent of LTI award vests; - Between 50th to 75th percentile – 50 per cent to 100 per cent of LTI award vests (pro-rata on a straight line basis); and - Above 75th percentile – 100 per cent of LTI award vests. Comparator Group The comparator group consists of Albemarle Corporation, Core Lithium Ltd, Critical Elements, Frontier Lithium, IGO Limited, Pioneer Limited, Liontown Resources Limited, Lithium Americas Corp., Lithium Ionic, Mineral Resources Limited, Patriot Battery Metals, Pilbara Minerals Limited, Sigma Lithium Corporation, Standard Lithium Ltd, Vulcan Energy Resources Limited, and Winsome Resources Ltd, provided each company remains listed on a recognised stock exchange for the measurement period. Measurement Period Equity rights will be assessed over a three (3) year measurement period commencing on 1 July each year and completing at the end of the three (3) year measurement period. Vesting Date Vesting will occur at the end of the three (3) year measurement period (i.e. 30 June), subject to performance and service conditions being satisfied. Expiry Date Equity rights will expire five (5) years after grant date. Retesting Performance conditions will be tested at the end of the three (3) year measurement period. If the performance conditions have not been met, the equity rights will lapse. No retesting of the performance hurdles will be performed. Forfeitures Unless the Board otherwise determines, equity rights will lapse on the earlier of cessation of employment of a participant or the vesting conditions not being achieved or being incapable of being achieved by a participant. Dividend and Voting Rights Equity rights carry no entitlement to voting, dividends or dividend equivalent payments. Restrictions Equity rights granted under the LTI plan may not be assigned, transferred, encumbered or otherwise disposed of by a participant unless the Board (in its sole and absolute discretion) approves, or the relevant dealing is effected by operation of law on death or legal incapacity of the participant. Cessation of Employment If an individual’s employment is terminated as a result of death or serious injury, disability or illness that prevents continued employment or total permanent disability, or in circumstances otherwise agreed between the Company and the individual, the Board has the discretion to determine that vesting of some or all equity rights should be accelerated. If an individual’s employment is terminated for any other reason, all unvested equity rights will automatically lapse, unless the Board determines (in its sole and absolute discretion) to allow some or all unvested equity rights to vest, in which case those unvested equity rights will vest immediately. Change of Control A change of control occurs when the Board advises participants that one or more persons acting in concert have acquired, or are likely to imminently acquire, control of the Company, as defined in section 50AA of the Corporations Act. In the event of a change of control, the Board has discretion to vest, lapse or keep the equity rights on foot. Board Discretion The Board has discretion to adjust the TSR vesting outcome in accordance with ASX Listing Rules so that the overall vesting outcome is appropriate and aligned with the objectives and principles of our remuneration framework. Malus and Clawback The Board may, at its discretion, reduce the number of shares to be received on vesting of an award, or clawback all vested and unvested LTI awards from a participant for a period of two years after the vesting or payment of an equity award.

Timeline for Delivery of Executive Remuneration The following chart provides a timeline of when remuneration is delivered under the remuneration framework: Year 1 Paid throughout the year Performance Period Performance Period Restriction Restriction Restriction FAR STI LTI Year 2 50% Cash Year 3 Year 4 50% Rights Vest 100% Rights Vest Malus, Clawback and Suspension Provisions Under our remuneration framework, malus, clawback and suspension provisions apply to all STI and LTI awards in cash or equity. Under both the malus and clawback provisions, the Board may, at its discretion, reduce the number of shares to be received on vesting of an award, or clawback all vested and unvested STI and LTI awards from a participant for a period of two years after the vesting or payment of a cash or equity award. These provisions apply to certain circumstances to ensure that employees do not obtain an inappropriate benefit. The circumstances in which the Board may exercise such discretion are broad, and could include: • any fraud or misconduct by an employee; • any material misstatement or misrepresentation, which would have affected the size of the award granted or vested; • a material error or misstatement in the Group’s results, which would have affected the size of the award granted or vested; • any circumstances in which any team or member of the Group in which the participant works or worked has been found guilty in connection with any regulatory investigation or has been in breach of any laws, rules or codes of conduct applicable to it or the standards reasonably expected of it; • any circumstances in which the Board determines that the personal performance of a participant does not justify vesting or where the participant’s conduct or performance has been in breach of their employment contract, any laws, rules or codes of conduct applicable to them or the standards reasonably expected of a person in their position; • an exceptional event which has had, or may have, a material adverse effect on the value or reputation of any member of the Group (excluding an exceptional event or events which have a material adverse effect on global macroeconomic conditions); • any circumstances in which the Board determines that there has been material damage to the Group’s social licence to operate; • a catastrophic safety or environmental event or events; • any significant unexpected or unintended consequence or outcome; and • any other factor which the Board deems justifiable. Under the suspension provisions, the Board may suspend the vesting or payment of an award for up to five years until the outcome of any internal or external investigation is concluded. The Board may then, at its discretion, reduce or lapse the participant’s award based on the outcome of that investigation. Where the suspension provision applies, the two-year clawback period will not extend beyond the period commencing from the original vesting date. Minimum Shareholding Requirement The Company has a minimum shareholding requirement for Executive KMP, equal to 100 per cent of base salary, to focus their efforts over the long-term and ensure alignment with shareholder interests. The minimum shareholding requirement must be obtained within three years of appointment as a member of Executive KMP by acquiring shares either directly on market or through the vesting of equity-based remuneration. As at 30 June 2025, Mr Brown and Mr Crawford (who was a member of Executive KMP for part of the financial year) had met the minimum shareholding requirement under our remuneration framework. Mr Collard, Mr Elder and Mr Dow have until January 2027, April 2027 and July 2027 respectively to meet the minimum shareholding requirement under our remuneration framework.

5. FY25 Performance and Executive Remuneration Outcomes Determination of Short-Term Incentive Outcomes As outlined in our remuneration framework, the STI plan is designed to reward executives to drive short-term performance by focusing participants on delivery of key business priorities set by the Board, both in the financial year and into the future. The overall STI outcome for Executive KMP is determined by assessing two key inputs: the Business Scorecard and individual performance. Business Scorecard The Business Scorecard includes a balanced set of challenging measures that consider both financial and non-financial performance. The Business Scorecard is cascaded throughout the organisation and is used to focus the efforts of executives and employees on outcomes that are a priority for the Board for a particular year. Individual Performance Individual performance is measured based on delivery against relevant operational or functional plans and individual performance goals. Our people are also assessed on demonstrated behaviours in performing their work and achieving their individual performance goals in alignment with our values (i.e. individual performance assessed on what is achieved and how it is achieved). Executive KMP are assessed on their contribution to the achievement of the Business Scorecard (Business Outcome) and individual performance (Individual Outcome). The overall STI outcome for Executive KMP is calculated based on the following weightings: • Managing Director and Chief Executive Officer – 80 per cent weighting to Business Outcome, 20 per cent weighting to Individual Outcome; • Other Executive KMP – 70 per cent weighting to Business Outcome, 30 per cent weighting to Individual Outcome. The following diagram summarises the methodology used to calculate the overall STI outcome: 0%–100% Individual Performance and Behaviours Business Outcome Individual Outcome 0%–100% Business Scorecard Maximum 100% Target 67% Overall STI Outcome Sayona Annual Report 2025 63

FY25 Business Scorecard The STI plan rewards executives for driving short-term performance through the achievement of weighted performance measures set by the Board at the beginning of the year. The following table summarises the STI performance measures and outcomes for the year ended 30 June 2025: Measure Performance(1) Weighting (A) % Performance Assessment(2) (B) % Business Outcome (A x B) % Sustainability Target Met 25.0% 65.9% 16.5% Health and Safety • Zero fatalities • 30 per cent year on year reduction in Total Recordable Injury Frequency Rate (TRIFR) (FY24 TRIFR: 28.6)(3). • Field Leadership Program Compliance — measured by number of activities undertaken compared to plan. Target Met • Zero fatalities. • TRIFR decreased by 27.2 per cent compared to FY24 baseline. • Planned and additional activities resulted in a completion rate of 134 per cent.

FY25 Individual Performance The Board assesses individual performance outcomes of Executive KMP based on delivery against relevant operational or functional plans and individual performance goals. Our people are also assessed on demonstrated behaviours in performing their work and achieving their individual performance goals, which considers leadership behaviours aligned to our values, risk framework and governance processes (i.e. individual performance assessed on what is achieved and how it is achieved). The individual outcomes applied to Executive KMP reflect the performance outcomes in their areas of accountability. These outcomes were 100 per cent, as indicated in the table below. Short-Term Incentive Outcomes The FY25 STI award for Executive KMP is determined through the Board’s assessment of business and individual outcomes, as summarised in the following table: Percentage of Maximum STI Award KMP Business Outcome(1) % Individual Outcome(2) % Overall STI Outcome(3) % Total STI Awarded(4) % Cash $ Deferred Rights $ Maximum STI Award(5) $ Awarded % Forfeited % Executive Directors J Brown(6) – – – – – – – – – L Dow 51.0 100.0 60.8 446,880 223,440 223,440 735,000 61 39 Other Executive KMP S Collard(7) 51.0 100.0 65.7 392,737 196,368 196,369 597,773 66 34 D Elder 51.0 100.0 65.7 264,607 132,303 132,304 402,750 66 34 (1) The Business Outcome reflects the performance outcome as a percentage of the maximum opportunity.

Equity Rights Vested, Forfeited or Lapsed No equity rights vested, forfeited or lapsed for KMP during the year. Options Exercised, Forfeited or Lapsed The following table summarises the number of options that were exercised, forfeited or lapsed for KMP during the year: KMP Award Opening balance as at 1 July 2024 # Options exercised # Options forfeited / lapsed # Fair value of options granted $ Fair value of options forfeited / lapsed $ Value of options on exercise(1) $ Value of shares in excess of exercise value(2) $ P Crawford FY23 Transitional Award 10,000,000 – 10,000,000 300,000 300,000 – – (1) ‘Value of options on exercise’ is the number of options exercised multiplied by the exercise price on the date of exercise. This reflects the value of funds received by the Company on exercise of the options. (2) ‘Value of shares in excess of exercise value’ is the number of options exercised multiplied by the closing share price of ordinary fully paid shares in Sayona Mining Limited on the date of exercise. This reflects the value added or lost compared to the exercise price. Sayona Annual Report 2025 66

6. Non-Executive Director Remuneration Components of Non-Executive Remuneration The remuneration of Non-Executive Directors is determined by the Board and is fixed to encourage impartiality, high ethical standards and independence. Non-Executive Directors are not entitled to retirement benefits other than statutory superannuation or other statutory benefits. Non-Executive Directors do not participate in STI or LTI plans designed for executives or employees. The remuneration framework proposes that Non-Executive Director remuneration is comprised of the following components: Description Purpose Fixed Remuneration Board Fees • Market-competitive fee paid to the Non-Executive Directors of Sayona Mining Limited, consisting of a base fee inclusive of statutory entitlements (i.e. pension or superannuation). • Board fees are a guaranteed, fixed element of remuneration (i.e. remuneration does not include an ‘at risk’ element). • Board fees reflect the size, complexity and global nature of our business and the responsibilities of serving on our Board. • To assist with attraction and retention of appropriately skilled and experienced Non-Executive Directors from a diverse global pool. • To preserve the independence of Non-Executive Directors and impartiality and high ethical standards. Committee Fees • Committee Chair and Committee Member fees (as applicable) paid to Non-Executive Directors (excluding the Non-Executive Chair) who serve on each Committee(1). • To recognise additional responsibilities associated with participating on each Committee. (1) The Non-Executive Chair (which is currently vacant) is paid a fixed fee for all responsibilities, including participation on any Committees. Non-Executive Director Fees The Board recognises the increased scrutiny and expectations placed on Boards and Committees over the last few years, and the range and complexity of matters considered by Committees of ASX listed companies. During the year, the Board reviewed and benchmarked our Non-Executive Director fees against industry and ASX peer data, taking into consideration the size and complexity of the business. To align with market practice, the Board approved the following changes to Non-Executive Director fees: • Non-Executive Chair fee of $300,000 per annum; • Committee Chair fee of $25,000 per annum for each Committee; • Committee Member fee of $12,500 per annum for each Committee. The following table outlines Non-Executive Director fees inclusive of statutory entitlements (i.e. pension or superannuation), effective as at 30 June 2025: Fee Position 2025 $ 2024 $ Variance % Board Fees Non-Executive Chair(1, 2) 300,000 300,000 – Non-Executive Director 125,000 125,000 – Committee Fees(2) Committee Chair 25,000 25,000 – Committee Member 12,500 12,500 – (1) The position of Non-Executive Chair was vacant from 1 July 2024 to 30 June 2025 and therefore no fee was paid during the year. (2) The Non-Executive Chair is paid a fixed fee for all responsibilities and would not receive additional fees for participation on any Committees. The maximum aggregate fee pool for Non-Executive Directors is currently $900,000 which was approved by shareholders at the Annual General Meeting on 30 November 2023. However, at the Company’s Extraordinary General Meeting on 31 July 2025, shareholders approved an increase in the aggregate amount of remuneration that may be paid to Sayona’s Non-Executive Directors from $900,000 to $1,250,000 per annum. This approved increase is subject to and conditional upon completion of the merger with Piedmont Lithium Inc. There was no increase in base fees for Non-Executive Directors in FY25 and following completion of the merger with Piedmont, there will be no increase in base fees for Non-Executive Directors for FY26. Sayona Annual Report 2025 67

Minimum Shareholding Requirement The Company has a minimum shareholding requirement for Non-Executive Directors, equal to 100 per cent of base Board fees, to ensure alignment with shareholder interests. The minimum shareholding requirement must be obtained within three years of appointment as a Non-Executive Director by acquiring shares directly on market. As at 30 June 2025, Mr Buckler and Mr Crawford (who was a Non-Executive Director for part of the financial year) had met the minimum shareholding requirement under our remuneration framework. Mr Lucas and Ms Lefcourt have until August 2026 and October 2027 respectively to meet the minimum shareholding requirement under our remuneration framework.

Unless the Board determines otherwise, equity rights will lapse on the earlier of cessation of employment of a participant or the vesting conditions not being achieved or being incapable of being achieved by a participant. As equity rights are subject to service and/or performance conditions, the minimum possible value of rights granted in future financial years is nil and the maximum possible value is the number of rights multiplied by the market price of fully paid ordinary shares in Sayona Mining Limited on the date of vesting. (2) The number of equity rights granted to Executive KMP during the year is calculated by dividing the face value of the award by the VWAP of ordinary fully paid shares in Sayona Mining Limited traded on the ASX over the ten (10) trading days following the announcement of the annual financial results, being $0.0250. The fair value per right for awards granted during the year is the grant date fair value for accounting purposes, being $0.0320 for the FY24 Deferred STI award, $0.0270 for the FY24 Transitional Management Incentive award, $0.0320 for the FY25 Deferred STI award, and $0.0263 for the FY25 LTI award. The grant of equity rights to the Managing Director and Chief Executive Officer were approved by shareholders, under ASX Listing Rule 10.14, at the Annual General Meeting on 28 November 2024.

8. Looking Forward Planned Remuneration Changes The Board has confidence in the integrity of the remuneration framework and believes it incorporates the necessary flexibility to reward executives for performance that is aligned with the creation of shareholder value. Following completion of the merger, the newly constituted Elevra Board will review the existing remuneration structure for the consolidated group and determine any appropriate changes, if required. 9. Additional Statutory Information Agreements, Notice Periods and Termination Remuneration and other terms of employment for Executive KMP are formalised in employment agreements. These employment agreements specify the components of remuneration, benefits and notice periods. Participation in the STI and LTI plans is subject to the Board’s discretion. The following table summarises the employment agreements in place with Executive KMP as at 30 June 2025: Executive KMP Position Term of agreement Notice period by either party Termination benefit L Dow Managing Director and Chief Executive Officer No fixed term 6 months 6 months J Brown Executive Director No fixed term 3 months 3 months S Collard President and Chief Operating Officer, Canada No fixed term 3 months 3 months D Elder Chief Financial Officer No fixed term 3 months 3 months In the case of dismissal for cause, the Company may terminate employment without notice and without payment of any salary or compensation in lieu of notice. The Board will apply the malus and clawback provisions under our remuneration framework, and outstanding awards under any of the Group’s incentive plans may be forfeited and previous awards clawed back. On appointment to the Board, all Non-Executive Directors enter into a service agreement with the Company in the form of a letter of appointment which details remuneration arrangements. Other Transactions with KMP and Related Parties There were no other transactions between the Group and KMP or their related parties, other than those disclosed above and elsewhere in the financial report, that were conducted other than in accordance with normal employee, customer, or supplier relationships on terms no more favourable than those reasonably expected under arm’s length dealings with unrelated persons. Prohibition of Hedging KMP or closely related parties of KMP are prohibited from entering hedge arrangements that would have the effect of limiting the risk exposure relating to their remuneration. In addition, the Board’s remuneration framework prohibits KMP from using Sayona’s shares as collateral in any financial transactions, including margin loan arrangements. The Directors’ Report, incorporating the Remuneration Report, is approved in accordance with a resolution of the Board.

Notes to the Financial Statements Basis of Preparation These consolidated financial statements and notes represent those of Sayona Mining Limited ("the Company”) and its controlled entities (the “Consolidated Group” or “Group”). Where an accounting policy, critical accounting estimate, assumption or judgement is specific to a note, these are described within the note to which they relate. These material policies have been consistently applied to all periods presented, except as described in Note 3. The consolidated financial statements of the Group for the year ended 30 June 2025 were authorised for issue in accordance with a resolution of the Directors on 28 August 2025. 1. Reporting Entity Sayona Mining Limited is a for-profit company limited by shares, incorporated and domiciled in Australia with a primary listing on the Australian Securities Exchange (ASX) and a secondary listing on the OTCQB Venture Market in the United States (OTCQB). The nature of the operations and principal activities of the Group are described in the Directors’ Report. The separate financial statements of the parent entity, Sayona Mining Limited, have been presented in Note 33 of this report as required by the Corporations Act 2001. 2. Basis of Preparation The consolidated financial statements are general purpose financial statements which have been prepared in accordance with the requirements of the Corporations Act 2001, Australian Accounting Standards and other authoritative pronouncements of the Australian Accounting Standards Board (AASB), and International Financial Reporting Standards (IFRS) and other authoritative pronouncements of the International Accounting Standards Board (IASB). The financial statements have been prepared on a going concern basis as management has assessed that the Group will be able to meet its obligations as and when they fall due and there is no significant uncertainty over the Group’s ability to continue as a going concern for the twelve months from the date of this report. The consolidated financial statements have been prepared on a historical cost basis, except for certain financial assets and liabilities (including derivative financial instruments) which are required to be measured at fair value. All amounts are presented in Australian dollars, with values rounded to the nearest thousand in accordance with ASIC Corporations Instrument 2016/191, unless otherwise stated. Where required by Accounting Standards, comparative figures have been reclassified for consistency with changes in presentation for the current financial year. (a) Principles of consolidation The consolidated financial statements comprise the financial statements of the Group. A list of controlled entities (subsidiaries) is provided in Note 26. Intercompany transactions, balances and unrealised gains or losses on transactions between Group entities are fully eliminated on consolidation. Subsidiaries are consolidated from the date on which control is obtained to the date on which control is ceased. (b) Critical accounting estimates and judgements The preparation of the consolidated financial statements requires management to apply accounting policies and methodologies based on complex and subjective judgements and estimates. Estimates assume a reasonable expectation of future events and are based on historical experience and assumptions as well as current trends and economic data, obtained both externally and within the Group. The use of these estimates, assumptions and judgements affects the amounts reported in the consolidated financial statements. The areas involving a higher degree of judgement or complexity, or where assumptions and estimates are material to the financial statements, are disclosed in the following notes: Note 5 Revenue 8 Tax 13 Property, Plant and Equipment 14 Impairment of Non-Financial Assets 17 Provisions (c) Foreign currency translation The consolidated financial statements are presented in Australian dollars, which has been assessed by management as the functional currency of the Company. Management will reassess the Company’s functional currency if there are any changes which impact the primary economic environment of the Group. Transactions denominated in foreign currencies are initially translated into Australian dollars using the exchange rate on the date of the underlying transaction. Monetary assets and liabilities denominated in foreign currencies are translated using the exchange rate at the end of the reporting period. Exchange gains or losses on settlement or translation of monetary items are included in the Consolidated Statement of Profit or Loss, except for foreign exchange differences resulting from translation of foreign operations, which are initially recognised in the Consolidated Statement of Comprehensive Income and subsequently transferred to the Consolidated Statement of Profit or Loss on disposal of the foreign operation. Non-monetary items measured on a historical cost basis in a foreign currency are translated into Australian dollars using the exchange rate on the date of the underlying transaction. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rate on the date when the fair value is determined. Exchange gains or losses on translation of non-monetary items measured at fair value are recognised in the same manner as gains or losses on change in fair value of the non-monetary item. Sayona Annual Report 2025 80

Notes to the Financial Statements 2. Basis of Preparation (continued) I; Goods and Services Tax (GST) and Québec Sales Tax (QST) Revenues, expenses and assets are recognised net of the amount of GST/QST, except where the amount of GST/QST incurred is not recoverable from the taxation authority. Receivables and payables are stated inclusive of the amount of GST/QST receivable or payable. The net amount of GST/QST recoverable from, or payable to, the taxation authority is included within other receivables or payables in the Consolidated Statement of Financial Position. Cash flows are presented on a gross basis. The GST/QST component of cash flows arising from investing or financing activities are presented as operating cash flows. 3. New Standards and Interpretations (a) New accounting standards and interpretations effective from 1 July 2024 The following new accounting standards and interpretations have been published and are effective for the year ended 30 June 2025: AASB 2020-1 and AASB 2022-6: Amendments to Australian Accounting Standards – Non-Current Liabilities with Covenants The amendments to AASB 101 Presentation of Financial Statements require a liability to be classified as current when the Group does not have a substantive right to defer settlement at the end of the reporting period. Only covenants with which the Group must comply on or before the reporting date affect the classification of a liability as current or non-current. Covenants with which the Group must comply after the reporting date (i.e. future covenants) do not affect a liability’s classification at that date. However, when non-current liabilities are subject to future covenants, the Group is now required to disclose information to help users of financial statements understand the risk that those liabilities could become repayable within twelve months after the reporting date. AASB 2023-1: Amendments to Australian Accounting Standards – Supplier Finance Arrangements The amendments to AASB 107 Statement of Cash Flows and AASB 7 Financial Instruments: Disclosures require the Group to provide additional disclosures about its supplier finance arrangements to enable users of financial statements to assess how supplier finance arrangements affect the Group’s liabilities, cash flows and exposure to liquidity risk. The amendments require the Group to disclose the terms and conditions of the arrangements, the carrying amount of the liabilities that are part of the arrangements, the carrying amounts of those liabilities for which the suppliers have already received payment from the finance providers, the range of payment due dates, and the effect of non-cash changes. The Group has reviewed these amendments and concluded that none of these changes are likely to have a material impact on the Group. (b) New accounting standards and interpretations issued but not yet effective The following new accounting standards and interpretations have been published but are not yet effective for the year ended 30 June 2025 and have not been early adopted by the Group: AASB 2023-5: Amendments to Australian Accounting Standards – Lack of Exchangeability – effective date 1 January 2025 The amendments to AASB 121 The Effects of Changes in Foreign Exchange Rates clarify when a currency is exchangeable into another currency and how a company estimates a spot rate when a currency lacks exchangeability. Disclosures are required to help users of financial statements assess the impact of using an estimated exchange rate on the financial statements. AASB 2024-2: Amendments to Australian Accounting Standards – Classification and Measurement of Financial Instruments – effective date 1 January 2026 The amendments to AASB 9 Financial Instruments and AASB 7 Financial Instruments: Disclosures: a) provide clarification on the timing of recognition and derecognition of financial assets and financial liabilities, particularly when they are settled using electronic payment systems. The amendment also provides an exception, if certain criteria are met, for the timing of derecognition of certain financial liabilities settled using an electronic payment system; b) provide further guidance about specific types of financial assets, specifically contractually linked instruments (CLIs); c) provide clarification of the classification of financial assets that are linked to environmental, social and governance (ESG) and similar characteristics; and d) require additional disclosure requirements with respect to investments in equity instruments measured at fair value through other comprehensive income and financial instruments with contingent features. AASB 2014-10: Sale or Contribution of Assets between an Investor and its Associate or Joint Venture (Amendments to AASB 10 and AASB 128) – effective date 1 January 2025 The amendments to AASB 10 Consolidated Financial Statements and AASB 128 Investments in Associates and Joint Ventures remove the inconsistency in dealing with the sale or contribution of assets between an investor and its associate or joint venture. A full gain or loss is recognised when a transaction involves a business (whether it is housed in a subsidiary or not). A partial gain or loss is recognised when a transaction involves assets that do not constitute a business, even if these assets are housed in a subsidiary. Sayona Annual Report 2025 81

Notes to the Financial Statements 3. New Standards and Interpretations (continued) (b) New accounting standards and interpretations issued but not yet effective (continued) AASB 18: Presentation and Disclosure in Financial Statements – effective date 1 January 2027 AASB 18 Presentation and Disclosure in Financial Statements will replace AASB 101 Presentation of Financial Statements. AASB 18 Presentation and Disclosure in Financial Statements will: a) better align the presentation of the statement of profit or loss to the categories in the statement of cash flows by introducing two new defined subtotals – operating profit and profit before financing and income taxes (EBIT); b) require disclosure of management-defined performance measures – subtotals of income and expenses not specified by IFRS Accounting Standards that are used in public communications to communicate management’s view of an aspect of a company’s financial performance (such as funds from operations, cash profit, etc); and c) enhance the requirements for aggregation and disaggregation to help a company to provide useful information. The Group does not intend to early adopt any of the new standards or interpretations. It is expected that where applicable, these standards and interpretations will be adopted on each respective effective date. Sayona Annual Report 2025 82

Notes to the Financial Statements Financial Performance This section details the results and financial performance of the Group including profitability and earnings per share. 4. Segment Reporting (a) Identification of reportable segments The Group is an emerging lithium producer with operations in Australia and Canada. The principal activities of the Group during the year were lithium mining and processing at North American Lithium and ongoing identification, evaluation and development of its portfolio of mineral exploration assets in Australia and Canada, predominantly focusing on lithium. Management has determined the operating segments based on the reports that are used by the Executive Leadership Team (the chief operating decision makers) and Board of Directors to make strategic decisions. Due to the geographically disparate nature of the operations, management examines the Group’s financial performance and activity from a geographical perspective. During the year, the reportable segments for the Group were segregated between Australian operations, Canadian operations and Corporate activities. The principal activities of each reportable segment are summarised as follows: Reportable segment Principal activities Australian operations Operations located in Western Australia, Australia Lithium and gold projects Exploration of lithium and gold tenements in the Pilbara and Yilgarn regions Canadian operations Operations located in Québec, Canada Abitibi-Témiscamingue Hub North American Lithium (NAL) Lithium mining and processing Authier Lithium Project Hard rock lithium deposit Pontiac Claims Exploration site for lithium pegmatite occurrences Tansim Lithium Project Exploration site for lithium, tantalum and beryllium Vallée Lithium Project Mineral rights claims located adjacent to NAL Eeyou Istchee James Bay Hub Lac Albert Lithium Project Exploration site for lithium pegmatite occurrences Moblan Lithium Project Hard rock lithium deposit host to high-grade spodumene mineralisation Troilus Claims Wholly owned claims located adjacent to the Moblan Lithium Project Corporate Corporate activities not directly related to operations (b) Segment results The segment information reflects the Group’s interest in subsidiaries and joint operations on a proportional consolidation basis. The segment information includes non-IFRS financial measures. Segment performance is measured by Underlying EBITDA. Underlying EBITDA is earnings before underlying depreciation and amortisation expense, underlying earnings adjustments, net financial income and expenses, and income tax expense. Reconciliations of underlying segment information to statutory information included in the Group’s consolidated financial statements are set out in Note 4 (c). Sayona Annual Report 2025 83

Inter-segment transactions Inter-segment transactions are made on a commercial basis. All such transactions are eliminated on consolidation of the Group's financial statements. Segment assets Where an asset is used across multiple segments, the asset is allocated to the segment that receives the majority of the economic value from the asset. In most instances, segment assets are clearly identifiable on the basis of their nature and physical location. Segment liabilities Liabilities are allocated to segments where there is a direct nexus between the incurrence of the liability and the operations of the segment. Sayona Annual Report 2025 84

Revenue 2025 $’000 2024 $’000 Sales revenue from contracts with customers 230,165 254,597 Other revenue (1) (6,800) (53,724) Total revenue (2) 223,365 200,873 (1) Other revenue relates predominantly to provisional pricing adjustments recognised at fair value. (2) Revenue relates solely to the sale of spodumene concentrate from North American Lithium. Refer to Note 5 (b) for a disaggregation of revenue by primary geographical market. Recognition and measurement The Group generates revenue primarily from the production and sale of spodumene concentrate. Revenue from the sale of goods is recognised at the point in time in which control of the product passes to the customer based upon agreed delivery terms. In most instances, control passes when the product is loaded onto the vessel and the bill of lading is received, or the product is delivered to a destination specified by the customer. In cases where control of the product is transferred to the customer before shipping takes place, revenue is recognised when the customer has formally acknowledged their legal ownership of the product, which includes all inherent risks associated with control of the product. The amount of revenue recognised reflects the consideration which the Group expects to be entitled in exchange for transferring the goods to the customer. In some instances, the amount of revenue to be received is provisionally priced and recognised at the estimate of the consideration receivable that is highly probable of not reversing by reference to the relevant contractual price and the estimated product specifications. Provisionally priced sales are subsequently repriced at each reporting period up until when final pricing and settlement is confirmed, with revenue adjustments relating to the quantity and quality of goods sold being recognised in sales revenue. Provisionally priced sales in which final pricing is referenced to a relevant index include an embedded commodity derivative. The embedded derivative is carried at fair value through profit or loss and presented as part of trade payables or receivables. The period between provisional pricing and final invoicing is typically between 60 and 120 days, with invoices payable on terms of up to 30 days. (a) Provisional pricing adjustments The Group’s sales contracts may provide for provisional pricing of sales at the time the product is delivered to the vessel, with final pricing determined using a relevant index price on or after the vessel’s arrival at the port of discharge. This provisional pricing relates to the quantity and quality of the commodity sold, which is included in sales revenue, and an embedded derivative relating to the price of the commodity sold. Provisional pricing adjustments relating to the embedded derivative are separately identified as movements in the financial instrument rather than being included within sales revenue. The pricing adjustment mechanism is separated from the host contract and recognised at fair value through profit or loss in accordance with AASB 9 Financial Instruments. These amounts are disclosed separately as provisional pricing adjustments within other revenue rather than being included within sales revenue. Key judgements and estimates Estimating variable consideration Revenue is measured at the fair value of the consideration received or receivable. The Group recognises revenue when the amount of revenue can be reliably measured, it is probable that future economic benefits will flow to the entity and specific criteria have been met for each of the Group’s performance obligations. Judgement is exercised in estimating variable consideration. This is determined by past experience with respect to returned goods where the customer maintains a right of return pursuant to the customer contract or where the sale of goods or services has a variable component. Revenue will only be recognised to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognised under the contract will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

Current and deferred tax expense is calculated using the tax rates enacted or substantively enacted at the end of the reporting period and includes any adjustment to tax payable in respect of previous years. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation and considers whether it is probable that a taxation authority will accept an uncertain tax treatment. The Group measures its tax balances based on the most likely amount or the expected value, depending on which method provides a better prediction of the resolution of the uncertainty.

Deferred tax is provided using the balance sheet liability method, providing for the tax effect of temporary differences between the tax bases of assets and liabilities and their carrying values in the consolidated financial statements. The tax effect of certain temporary differences is not recognised, principally with respect to: • temporary differences on the initial recognition of assets or liabilities in a transaction that: (a) is not a business combination; and (b) at the time of the transaction: (i) affects neither accounting nor taxable profit or loss; and (ii) does not give rise to equal taxable and deductible temporary differences; • temporary differences related to investments in subsidiaries, associates and joint arrangements to the extent that the Group is able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future; and • taxable temporary differences arising on the initial recognition of goodwill. Deferred tax assets relating to temporary differences and unused tax losses are recognised only to the extent that it is probable that future taxable profits will be available against which the benefit of the deferred tax assets can be utilised. Deferred tax assets are reviewed at each reporting period and amended to the extent that it is no longer probable that the related tax benefit will be realised. Deferred tax assets and liabilities are offset when they relate to income taxes levied by the same tax authority and the Group has both the right and the intention to settle its current tax assets and liabilities on a net or simultaneous basis.

(f) Tax losses carried forward At 30 June 2025, tax losses subject to expiry for which no deferred tax asset was recognised total $363.5 million (2024: $290.6 million), expiring between 2037 and 2045 (2024: 2037 to 2044). (g) Tax consolidation Sayona Mining Limited and its wholly owned Australian resident subsidiaries formed a tax consolidated group with effect from 1 July 2015 and is therefore taxed as a single entity from that date. Sayona Mining Limited is the head entity of the tax consolidated group. Income tax expense and deferred tax assets and liabilities arising from temporary differences of the members of the tax consolidated group are recognised in the separate financial statements of the members of the tax consolidated group using the “separate taxpayer within group” approach by reference to the carrying values in the separate financial statements of each entity and the relevant tax values under tax consolidation. Current tax assets and liabilities and deferred tax assets arising from unused tax losses and relevant tax credits of the members of the tax consolidated group are recognised by the Company (as head entity of the tax consolidated group). Tax funding arrangements are currently in place between entities in the tax consolidated group. Key judgements and estimates Deferred tax Judgement is required in assessing whether deferred tax assets and certain deferred tax liabilities are recognised in the Consolidated Statement of Financial Position. Deferred tax assets are recognised only where it is considered more likely than not that they will be recovered, which is dependent on the generation of sufficient future taxable profits. Assumptions about the generation of future taxable profits depend on management’s estimates of future cash flows. These depend on estimates of future production and sales volumes, commodity prices, reserves, operating costs, mine closure and rehabilitation costs, capital expenditure and other capital management transactions. Uncertain tax matters – Unused tax losses on acquisition Tax benefits acquired as part of a business combination, but not satisfying the criteria for separate recognition at that date, are recognised subsequently if new information about facts and circumstances arises. The adjustment is treated as a reduction to goodwill if it has occurred during the measurement period. If it occurs outside the recognition period, the adjustment is recognised in the Consolidated Statement of Profit or Loss. Sayona Annual Report 2025 90

(1) The weighted average number of contingently issuable ordinary shares as at 30 June 2025 is 273.8 million (2024: 14.7 million). The inclusion of these contingently issuable ordinary shares would have the effect of reducing the loss per share. Accordingly, these potential ordinary shares have not been included in the determination of diluted earnings per share. Basic earnings per share Basic earnings per share amounts are calculated based on profit or loss attributable to equity holders of Sayona Mining Limited and the weighted average number of ordinary shares outstanding during the year. Diluted earnings per share Dilutive earnings per share amounts are calculated based on profit or loss attributable to equity holders of Sayona Mining Limited and the weighted average number of ordinary shares outstanding after adjustment for the effects of all dilutive potential ordinary shares.

Recognition and measurement Trade receivables are generally due within 30 days and are initially recognised at their transaction price, or fair value for those receivables containing a significant financing component. Trade receivables are subsequently measured at amortised cost using the effective interest method, less an allowance for expected credit losses, except for provisionally priced receivables which are subsequently measured at fair value through profit or loss in accordance with AASB 9 Financial Instruments. GST/QST receivable from taxation authorities is initially recognised at fair value and subsequently measured at amortised cost using the effective interest method, less an allowance for expected credit losses. The collectability of trade and other receivables is assessed continuously. Individual receivables which are deemed to be unrecoverable are written off by reducing the carrying value directly. At the reporting date, specific allowances are made for any expected credit losses based on a review of all outstanding amounts. Information about the Group’s exposure to credit risks and expected credit losses for trade and other receivables is included in Note 23 (c). Sayona Annual Report 2025 92

Cost is determined primarily on the basis of average cost. For processed inventories, cost is derived on an absorption costing basis. Cost comprises the cost of purchasing raw materials and the cost of production, including attributable overheads. Net realisable value is calculated as the estimated proceeds of sale, less an estimate of all further costs required to the stage of completion and all applicable marketing, selling and distribution costs to be incurred. Raw materials and consumables Raw materials and consumables represent spares, consumables and other supplies yet to be utilised in the production process, except where the raw materials purchased are equivalent products to those that the Group produces and would otherwise classify as work in progress.

Sayona Annual Report 2025 94

Notes to the Financial Statements 13. Property, Plant and Equipment (continued) Recognition and measurement Property, plant and equipment is recorded at cost less accumulated depreciation and impairment charges. Cost is the fair value of consideration given to acquire the asset at the time of its acquisition or construction and includes the direct cost of bringing the asset to the location and condition necessary for operation. Subsequent costs are included in the asset’s carrying value or recognised as a separate asset, as appropriate, only when it is probable that the future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. All other repairs and maintenance are recognised as expenses in profit or loss during the financial period in which they are incurred. An item of property, plant and equipment and any significant part initially recognised is derecognised upon disposal or when no future economic benefits are expected. Any gain or loss arising on derecognition of the asset is included in the Consolidated Statement of Profit or Loss when the asset is derecognised. (a) Mine properties Mine properties include: • capitalised development and production stripping costs; • capitalised exploration, evaluation and development expenditure where commercial viability has been demonstrated; and • mineral rights acquired. The initial cost of mine properties includes the purchase price or construction cost, any costs directly attributable to bringing the asset into operation, and borrowing costs (where relevant for qualifying assets). The purchase price or construction cost is the aggregate amount paid and the fair value of any other consideration given to acquire the asset. Mine properties also consist of the fair value attributable to mineral reserves and the portion of mineral resources considered to be probable of economic extraction at the date of acquisition. When a mine construction project moves into the production phase, the capitalisation of certain mine construction costs ceases, and costs are either regarded as part of the cost of inventory or expensed, except for costs which qualify for capitalisation. (i) Capitalised development and production stripping costs The process of removing overburden and other waste materials to access mineral deposits is known as stripping. Stripping is necessary to obtain access to mineral deposits and occurs throughout the life of an open-pit mine. Stripping is classified as either development stripping or production stripping. Development and production stripping costs are recognised as part of mine properties in property, plant and equipment. Development stripping costs are initial overburden removal costs incurred to obtain access to mineral deposits that will be commercially produced. These costs are capitalised when it is probable that future economic benefits in the form of access to mineral ores will flow to the Group and costs can be measured reliably. Stripping costs incurred during the development phase of a mine are usually capitalised as part of the depreciable cost of building, developing and constructing the mine. Production stripping costs are post initial overburden removal costs incurred during the normal course of production, which are usually incurred after the first saleable minerals have been extracted from the component of the ore body. Costs are capitalised where production stripping activity results in improved access to future ore and the following criteria are met: • the production stripping activity improves access to a specific component of the ore body and it is probable that economic benefits arising from the improved access to future ore production will be realised; • the component of the ore body for which access has been improved can be identified; and • costs associated with that component can be measured reliably. Production stripping costs are allocated between the inventory produced and the production stripping asset using a life-of-component waste-to-ore (or mineral contained) strip ratio. When the current strip ratio is greater than the estimated life-of-component ratio, a portion of the stripping costs are capitalised to the production stripping asset. (b) Capital works in progress Capital works in progress are measured at cost inclusive of associated on-costs and charges. Costs are only capitalised when it is probable that future economic benefits will flow to the Group and costs can be measured reliably. All assets included in capital works in progress are reclassified to other categories within property, plant and equipment when the asset is available and ready for use in the manner intended.

Notes to the Financial Statements 13. Property, Plant and Equipment (continued) (c) Right-of-use assets Right-of-use assets are presented within the respective categories of property, plant and equipment according to the nature of the underlying asset leased. Refer to Note 20 for details on the Group’s right-of-use assets and corresponding lease liabilities. (d) Exploration and evaluation expenditure Exploration and evaluation expenditure (including initial payments for the right to explore) is capitalised where it is considered likely to be recoverable or where the activities have not reached a stage that permits a reasonable assessment of the existence of reserves. Accumulated costs in relation to an abandoned area are written off in full against profit or loss in the year in which the decision to abandon the area is made. Exploration is defined as the search for potential mineralisation after the Group has obtained legal rights to explore in a specific area and includes topographical, geological, geochemical and geophysical studies and exploratory drilling, trenching and sampling. Evaluation is defined as the determination of the technical feasibility and commercial viability of a particular prospect. Activities conducted during the evaluation phase include determination of the volume, grade and quality of the deposit, examination and testing of extraction methods and metallurgical or treatment processes, surveys of transportation and infrastructure requirements, and market and finance studies. Recoverability of the carrying value of exploration assets is dependent on the successful exploration and development of projects, or alternatively, through the sale of the areas of interest. (e) Depreciation and amortisation The carrying values of property, plant and equipment are depreciated to their estimated residual values over the estimated useful lives of the specific assets concerned. Estimates of residual values and useful lives are reassessed annually and any change in estimate is considered in the determination of remaining depreciation charges. Depreciation commences on the date of commissioning. Property, plant and equipment is depreciated on a units of production or straight-line basis using the estimated lives indicated below, except for land, capital works in progress, and exploration and evaluation assets which are not depreciated. Where assets are dedicated to a mine or lease and are not readily transferable, the useful life of the asset is subject to the lesser of the asset’s useful life and the life of the mine or lease. Asset category Depreciation method Buildings 2 to 20 years straight-line Mine properties (including mineral rights) Based on ore reserves on a units of production basis Plant and equipment 2 to 20 years straight-line Right-of-use assets Based on the shorter of the asset’s useful life or term of the lease (straight-line) Key judgements and estimates Judgement applied in determining ore reserves and mineral resources The Group estimates its ore reserves and mineral resources based on information compiled by Competent Persons in accordance with the Joint Ore Reserves Committee (JORC) code. Estimation requires assumptions about future commodity prices and demand, exchange rates, production costs, transport costs, mine closure and rehabilitation costs, recovery rates, discount rates and, in some instances, the renewal of mining licences. There are many uncertainties in the estimation process and assumptions that are valid at the time of estimation may change significantly when new information becomes available. New geological or economic data, or unforeseen operational issues, may change estimates of ore reserves and mineral resources. The Group uses judgment as to when to include mineral resources in accounting estimates. Useful economic lives of assets The determination of useful lives, residual values and depreciation methods is reviewed at each reporting period and involves estimates and assumptions. Any changes to useful lives or any other estimates or assumptions may impact prospective depreciation rates and asset carrying values. The Group applies judgement in determining the useful economic lives of assets and whether any indicators of impairment are present based on internal and external sources of information available. The table above summarises the depreciation methods and rates applied to major categories of property, plant and equipment. Sayona Annual Report 2025 96

(2) The total impairment and write down of $271.3 million for the year ended 30 June 2025 relates to North American Lithium. The total impairment and write down of $17.1 million for the year ended 30 June 2024 relates to the Australian operations ($5.9 million), Corporate ($5.1 million), Vallée Lithium Project ($4.0 million), and various other individually immaterial projects ($2.1 million). Recognition and measurement Impairment tests for all non-financial assets (excluding goodwill) are performed when there is an indication of impairment. In testing for indications of impairment and performing impairment calculations, assets are considered as collective groups known as cash generating units (CGUs), being the smallest identifiable group of assets that generate cash inflows that are largely independent of the cash inflows generated from other assets or groups of assets. The Group assesses whether there is any indication that a CGU may be impaired at each reporting period. This assessment includes consideration of external and internal sources of information. If such an indication exists, the Group uses the higher of fair value less cost of disposal (FVLCD) and value in use to assess the recoverable amount of the asset. If the carrying value of a CGU exceeds its recoverable amount, the CGU is impaired and an impairment loss is recognised immediately in the Consolidated Statement of Profit or Loss. Where it is not possible to estimate the recoverable amount of an individual asset, the Group estimates the recoverable amount of the CGU to which the asset belongs. Previously impaired CGUs are reviewed for possible reversal of impairment at each reporting period. Impairment reversals cannot exceed the carrying value that would have been determined (net of depreciation) had no impairment loss been recognised for the CGU. Such reversal is recognised in the Consolidated Statement of Profit or Loss. Goodwill is not subject to impairment reversal. For areas not yet in production, any mineral rights acquired, together with subsequent capitalised exploration and evaluation expenditure, are reviewed for indicators of impairment to determine the appropriateness of continuing to carry forward costs in relation to that area of interest. Calculation of recoverable amount The recoverable amount is the higher of a CGU’s fair value less cost of disposal (FVLCD) and its value in use (VIU). Fair value less cost of disposal FVLCD is an estimate of the amount that a market participant would pay for a CGU less the cost of disposal. FVLCD for mineral assets is generally determined using independent market assumptions to calculate the present value of the estimated future post-tax cash flows expected to arise from the continued use of the asset, including the anticipated cash flow effects of any capital expenditure to enhance production or reduce cost, and its eventual disposal where a market participant may take a consistent view. Cash flows are discounted using an appropriate post-tax market discount rate to arrive at a net present value of the CGU, which is compared against the CGU’s carrying value. FVLCD may also take into consideration other market-based indicators of fair value. FVLCD is based primarily on Level 3 inputs as defined in Note 23 (d), unless otherwise stated. Value in use VIU is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and its eventual disposal or closure. VIU is determined by applying assumptions specific to the Group’s continued use and cannot take into account future development. These assumptions are different to those used in calculating FVLCD, and therefore a VIU calculation is likely to produce a different result (usually lower) to a FVLCD calculation.

Notes to the Financial Statements 14. Impairment of Non-Financial Assets (continued) (a) Impairment of non-current assets (excluding goodwill) North American Lithium The Group considers that North American Lithium (NAL) is a separate CGU as the cash inflows that it generates are largely independent of the cash inflows generated from other assets or groups of assets. For the year ended 30 June 2025, the Group identified several indicators of impairment for NAL, which subsequently led to an assessment of the carrying value of the NAL CGU. The key indicators of impairment included the decline in market capitalisation of the Company and a significant deterioration in market conditions, specifically relating to the price of spodumene concentrate. Background On 27 August 2021, the Group acquired 100 per cent of the issued capital of North American Lithium Inc., a Canadian-based mining and exploration company and former producer of spodumene concentrate from its integrated spodumene ore mine and processing facility in Québec, Canada. Following the acquisition, the Group invested significant funds into the operation to enable the restart of production in March 2023, with the first sale of spodumene concentrate under the Group’s ownership occurring in August 2023. Outcome The Group assessed the carrying value of the NAL CGU and recognised an impairment of $271.3 million for the year ended 30 June 2025 (2024: Nil). The recoverable amount of the NAL CGU was determined as $156.7 million based on its fair value less cost of disposal. Impairments relating to the NAL CGU were wholly allocated to property, plant and equipment. The impairment of $271.3 million to property, plant and equipment includes $164.8 million recognised in plant and equipment, $67.8 million recognised in mine properties, $25.3 million recognised in land and buildings, and $13.4 million recognised in capital works in progress. The impairment reflects a deterioration in the lithium market, which continues to place pressure on the market price for spodumene concentrate. These changes in market conditions have significantly reduced the recoverable amount of the NAL CGU compared to the prior period. Methodology and key assumptions The fair value measurement is categorised as a Level 3 fair value based on the inputs in the discounted cash flow valuation model over the life of mine period (refer to Note 23 (d)), and was calculated using a real, post-tax discount rate of 10.0 per cent. The key estimates and assumptions used in the determination of fair value less cost of disposal were: • spodumene concentrate prices; • foreign exchange rates; • operating and capital expenditure; • discount rate; • regulatory approvals; and • future production (i.e. Mineral Resource and Ore Reserve estimates). Key assumptions (real) Assumptions used Spodumene concentrate prices (US$ per tonne) US$655 – US$1,374 Foreign exchange rates (CAD/USD) 0.7332 Unit operating costs (C$ per tonne) C$923 – C$1,231 Discount rate (post-tax) 10.0% The recoverable amount is informed by a production and cost profile which is used for management’s planning processes. Operating and capital expenditure Cost assumptions are based on forecasted production levels, operating cost and capital expenditure requirements derived from the Group’s latest approved budget and life of mine plans. Future production The Mineral Resource and Ore Reserve estimates for NAL are reported in accordance with the JORC Code and ASX Listing Rules. Refer to the Mineral Resources and Ore Reserves section of this report for further information on these estimates. Sayona Annual Report 2025 98

Notes to the Financial Statements 14. Impairment of Non-Financial Assets (continued) The following table illustrates the sensitivity of the recoverable amount of the NAL CGU to a reasonable possible change in the aforementioned assumptions. Owing to the complexity of the relationships between each key assumption, the analysis is performed for each assumption individually (with all other assumptions held constant). Impact on recoverable amount A$ million Key assumptions (real) Change Favourable Unfavourable Spodumene concentrate prices (US$ per tonne) 10% 85.4 (87.6) Foreign exchange rates (CAD/USD) 10% 173.9 (153.9) Unit operating costs (C$ per tonne) 10% 121.3 (129.8) Discount rate (post-tax) 100 basis points 23.3 (20.7) Key judgements and estimates Determination of CGUs Judgement is applied to identify the Group’s CGUs, particularly when assets form part of integrated operations. A key judgement was applied in identifying the NAL operation as a single CGU. As a result, only the CGU assets and cash flows directly attributable to this operation were considered in the impairment assessment of the NAL CGU. Impairment testing and calculations An assessment of whether there is any indication of impairment and the calculation of a CGU’s recoverable amount requires management to make estimates and assumptions about expected production and sales volumes, commodity prices, foreign exchange rates, Mineral Resources and Ore Reserves, regulatory approvals, operating costs, closure and rehabilitation costs, future capital expenditure and allocation of corporate costs. These estimates and assumptions are subject to risk and uncertainty. There is a possibility that changes in circumstances will alter these projections, which may impact the recoverable amount. In such circumstances, some or all of the carrying value may be impaired or a previously recognised impairment charge may be reversed, with the impact recognised in the Consolidated Statement of Profit or Loss. The key estimates and assumptions used in the assessment of impairment are as follows: Commodity prices and market traded consumables Spodumene concentrate price assumptions are derived from broker market consensus pricing, calculated as the average of recent forecasts published by major independent investment banks and commodity analysts. Foreign exchange rates The foreign exchange rate assumption applied in the discounted cash flow model reflects the CAD/USD spot exchange rate as at 30 June 2025. Operating and capital expenditure Operating and capital cost assumptions are based on the Group’s latest approved budget and life of mine plans. Discount rate In determining fair value, the estimated future cash flows of the CGU have been discounted using a real, post-tax discount rate of 10.0 per cent (2024: 8.0 per cent). The discount rate applied is a risk-adjusted cost of capital management have deemed appropriate to the CGU. Regulatory approvals Life of mine plans include assumptions associated with the successful application and timing of ongoing and future regulatory approvals. Future production Life of mine plans based on Mineral Resource and Ore Reserve estimates and economic life of processing facilities. Where impairment testing is undertaken, a range of external sources are considered as further input to the above assumptions. Exploration and evaluation expenditure For areas not yet in production, acquired mineral rights, together with subsequent capitalised exploration and evaluation expenditure, require judgement to determine the likelihood of future economic benefits from future development, and whether sufficient data exists to indicate that, although a development in the specific area is likely to proceed, the carrying value of the exploration and evaluation asset is unlikely to be recovered in full. When facts and circumstances suggest that the carrying value exceeds the recoverable amount, an impairment test is required which may result in an adjustment to the carrying value of acquired mineral rights together with subsequent capitalised exploration and evaluation expenditure.

Recognition and measurement Trade and other payables represent the liabilities for goods and services received by the Group that remain unpaid at the end of the reporting period. The balance is recognised as a current liability, with amounts normally paid within 30 days of recognition of the liability. Amounts are initially recognised at fair value and subsequently measured at amortised cost, except for provisionally priced contracts which are held at fair value in accordance with AASB 9 Financial Instruments. The carrying value of trade and other payables is considered to approximate fair value due to the short-term nature of the payables, except for provisional pricing adjustments which are categorised as Level 2 in the fair value hierarchy. 16. Other Liabilities 2025 $’000 2024 $’000 Deferred income – 4,540 Flow through share premium liability (1) – 6,084 Total other liabilities – 10,624 Comprising: Current – 6,084 Non-current – 4,540 (1) Flow through share proceeds of $54.9 million, received by the Group in March 2023, were fully utilised as at 30 June 2025. Reclassification of deferred income to property, plant and equipment The Group performed a review of the royalty agreement with Lithium Royalty Corp. (LRC) and have reclassified amounts previously recognised as deferred income to property, plant and equipment. These reclassifications have been applied retrospectively to prior period comparatives. (a) Flow Through Shares Under Canadian taxation legislation, mining companies may issue flow through shares to finance eligible exploration programs. A flow through share arrangement enables an entity to incur qualifying exploration and evaluation expenditure and renounce the related income tax deductions to investors. On issuance, the entity allocates the proceeds from issuance between issued capital and the sale of tax benefits (or flow through share premium), which is equal to the estimated premium that investors pay for the flow through feature. Issued share capital is recognised at fair value with the residual value recognised as a flow through share premium liability. At initial recognition, the sale of tax benefits is deferred and presented as other liabilities in the Consolidated Statement of Financial Position as the entity has not yet fulfilled its obligations to pass on the tax deductions to investors. Upon expenditure being incurred, the entity derecognises the liability and recognises the premium as other income in the Consolidated Statement of Profit or Loss. The expenditure also gives rise to a deferred tax liability which is recognised as the difference between the carrying value and tax base of the qualifying expenditure. The Company has elected to apply the renunciation process prospectively and has relied upon the “look-back” rule which allows the Company to renounce eligible expenditures incurred up to an entire calendar year following the last day of the calendar year in which the flow through shares were issued.

Provisions are measured using the best estimate of the amounts required to settle the obligation at the end of the reporting period. (a) Employee benefits Employee entitlements to be settled within twelve months after the end of the reporting period are presented as current employee benefit obligations. Liabilities for salaries and wages, including non-monetary benefits, and annual leave are recognised in respect of employees’ services up to the end of the reporting period and are measured at the amounts expected to be paid when the liabilities are settled. A non-current provision for employee entitlements is recognised for annual leave and long service leave entitlements and bonus incentives which will not be settled within twelve months after the end of the reporting period in which the employees render the related service. Other non-current employee benefits are measured at the present value of the expected future payments to be made to employees. Expected future payments incorporate anticipated future wage and salary levels, durations of service and employee departures and are discounted at rates determined by reference to market yields at the end of the reporting period that have maturity dates that approximate the terms of the obligations. Any remeasurements for changes in assumptions of obligations for other non-current employee benefits are recognised in profit or loss in the period in which the changes occur. Sayona Annual Report 2025 101

Notes to the Financial Statements 17. Provisions (continued) (b) Mine closure and rehabilitation The mining and processing activities of the Group normally give rise to obligations for site closure or rehabilitation. Mine closure and rehabilitation works can include facility decommissioning and dismantling, removal or treatment of waste materials, and site and land rehabilitation in accordance with local laws and regulations and clauses of the permits. Mine closure and rehabilitation provisions are recognised at the time that environmental disturbance occurs. When the extent of disturbance increases over the life of an operation, the provision is increased accordingly. Costs included in the provision encompass all closure and rehabilitation activity expected to occur progressively over the life of the operation and at, or after, the time of closure, for disturbance existing at the reporting date. Routine operating costs that may impact the ultimate closure and rehabilitation activities, such as waste material handling conducted as an integral part of a mining or production process, are not included in the provision. Costs arising from unforeseen circumstances, such as the contamination caused by unplanned discharges, are recognised as an expense and liability when the event gives rise to an obligation which is probable and capable of reliable estimation. Mine closure and rehabilitation provisions are measured at the expected value of future cash flows, discounted to their present value and determined according to the probability of alternative estimates of cash flows occurring for each operation. When provisions for mine closure and rehabilitation are initially recognised, the corresponding cost is capitalised as an asset, representing part of the cost of acquiring the future economic benefits of the operation. The capitalised cost of closure and rehabilitation activities is recognised in property, plant and equipment and depreciated accordingly. Mine closure and rehabilitation provisions are also adjusted for changes in costs and estimates. Any adjustments are made prospectively and are accounted for as a change in the corresponding capitalised asset, except where a reduction in the provision is greater than the depreciated capitalised cost of the related assets, in which case the carrying value is reduced to nil and the remaining adjustment is recognised first against these related assets in property, plant and equipment, and subsequently to the Consolidated Statement of Profit or Loss. Adjustments to the estimated amount and timing of future closure and rehabilitation cash flows are a normal occurrence in light of the significant judgements and estimates involved. Key judgements and estimates Mine closure and rehabilitation provision of North American Lithium Mine closure and rehabilitation costs are uncertain, and cost estimates can vary in response to many factors including estimates of the extent of rehabilitation activities, technological changes, regulatory changes, cost increases including inflationary impacts and changes in discount rates. Assumptions have been made based on the current economic environment, which management believe are a reasonable basis upon which to estimate the future liability. These estimates are reviewed regularly to take into account any material changes to the assumptions. Actual rehabilitation costs will ultimately depend on market conditions at the relevant time. The timing of closure and rehabilitation will most likely depend on when the mine ceases to produce at economically viable rates. The recognition of mine closure and rehabilitation provisions requires judgement. The provision at reporting date represents management’s best estimate of the present value of future closure and rehabilitation costs. Sayona Annual Report 2025 102

Recognition and measurement All borrowings are initially recognised at their fair value net of directly attributable transaction costs. Subsequent to initial recognition, interest bearing liabilities are measured at amortised cost using the effective interest method. Gains and losses are recognised in the Consolidated Statement of Profit or Loss when the liabilities are derecognised. Interest bearing liabilities are classified as current liabilities, except when the Group has an unconditional right to defer settlement for at least twelve months after the reporting date, in which case the liabilities are classified as non-current. A reconciliation of movements in interest bearing liabilities and other financial liabilities to cash flows arising from financing activities is set out in Note 23 (e). (a) Contract liabilities On 21 June 2024, the Group entered into a contract with a trading company partner whereby North American Lithium may elect to receive up to US$30 million as advance payments based on the value of committed future sales of spodumene concentrate. Amounts received in advance are recognised against the provisional sale value as the performance obligations under the contract are satisfied, being the time when significant risks and rewards of ownership transfer to the customer, which typically aligns with the loading of the export vessel. This subsequently provides additional capacity under the limit of the contract. Amounts received in advance are unsecured, with interest paid quarterly on the outstanding amount at the Secured Overnight Financing Rate plus 2.4 per cent. The outstanding principal amount received in advance as at 30 June 2025 is US$29.4 million (2024: Nil) and is expected to be fully realised within the next twelve months.

Notes to the Financial Statements 19. Interest Bearing Liabilities (continued) (b) Non-convertible redeemable cumulative preference shares On 27 August 2021, as part of the acquisition of North American Lithium, the Group exchanged Investissement Québec’s (IQ) second ranking debt of C$63 million for twenty million non-convertible redeemable cumulative preference shares held by NAL at a par value of C$1.00 per share. The shares may be redeemed at the option of NAL or at the option of IQ, subject to satisfaction of various performance conditions. On 24 June 2024, IQ agreed to extend the delivery date of a feasibility study condition from 1 September 2024 to 1 December 2024. On 29 November 2024, IQ agreed to extend the delivery date of this condition to 1 April 2025. On 31 March 2025, IQ agreed to extend the delivery date of this condition to 1 July 2025. On 27 June 2025, IQ agreed to extend the delivery date of this condition to 28 August 2025. On 25 August 2025, IQ further agreed to extend the delivery date of this condition to 19 September 2025. The terms of the preference shares are detailed below: • interest is accrued or paid at 5 per cent per annum, except for the period from 1 September 2024 to 19 September 2025 in which interest is accrued or paid at 16.25 per cent per annum; • the shares cannot be converted to equity at any time; • preference shareholders are not entitled to dividends or to vote at shareholder meetings; • redemption commences in accordance with the NAL Constitution and Governance Agreement once the mine is in commercial operation and the redemption term is up to ten years after the first anniversary of the issue of these shares; and • in the event of default, liquidation, or receivership, IQ rank before the ordinary shareholders in priority. The preference shares are recorded at issue price plus accrued interest. Given the nature and conditions impacting on potential redemption terms, the fair value assigned to the preference shares is their face value. 20. Leases The nature of the Group’s leases predominantly relates to assets and equipment supporting the operations in line with the Group’s principal activities, as well as real estate in the form of office premises. Lease terms range from three to five years. Lease contracts are negotiated on an individual basis and contain a wide range of terms and conditions. (a) Amounts recognised in the Consolidated Statement of Financial Position The Consolidated Statement of Financial Position includes the following amounts relating to leases: 2025 $’000 2024 $’000 Right-of-use assets recognised in property, plant and equipment Land and buildings Cost 1,504 1,483 Accumulated depreciation and impairment (990) (709) Net book value 514 774 Plant and equipment Cost 7,255 7,121 Accumulated depreciation and impairment (6,372) (2,967) Net book value 883 4,154 Total right-of-use assets 1,397 4,928 Lease liabilities Land and buildings – current 414 373 Land and buildings – non-current 90 496 Plant and equipment – current 2,160 2,425 Plant and equipment – non-current – 2,121 Total lease liabilities 2,664 5,415 There were no right-of-use asset additions during the year (2024: $1.8 million).

Leases (continued) (b) Amounts recognised in the Consolidated Statement of Profit or Loss The Consolidated Statement of Profit or Loss includes the following amounts relating to leases: 2025 $’000 2024 $’000 Depreciation of right-of-use assets 2,749 2,795 Impairment of right-of-use assets (1) 923 – Interest on lease liabilities 409 678 (1) Refer to Note 14 for details on impairment and write down of non-financial assets. (c) Amounts recognised in the Consolidated Statement of Cash Flows The Consolidated Statement of Cash Flows includes the following amounts relating to leases: 2025 $’000 2024 $’000 Total cash outflow for leases 3,226 3,280 Recognition and measurement At inception of a contract, the Group assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. All contracts that are classified as short-term leases (leases with a remaining lease term of twelve months or less) and leases of low value assets are recognised as an operating expense on a straight-line basis over the term of the lease. Right-of-use assets If a lease is present, a right-of-use asset and corresponding lease liability is recognised at the commencement date of the lease. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and estimated future restoration costs, less any lease incentives received. The right-of-use asset is subsequently measured at cost less accumulated depreciation, impairment charges and any adjustments for remeasurement of the lease liability. Right-of-use assets are depreciated over the term of the lease or useful life of the underlying asset, whichever is the shortest. Where a lease transfers ownership of the underlying asset or the cost of the right-of-use asset indicates the Group is likely to exercise a purchase option, the specific asset is depreciated over the useful life of the underlying asset. Right-of-use assets are recognised in property, plant and equipment in the Consolidated Statement of Financial Position. Lease liabilities Lease liabilities are recognised within interest bearing liabilities in the Consolidated Statement of Financial Position. The lease liability is initially measured at the present value of the lease payments still to be paid at commencement date. Lease payments are discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the lessee’s incremental borrowing rate. The lessee’s incremental borrowing rate is the rate of interest that a lessee would have to pay to borrow the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment and with similar terms, conditions and security. The lease liability is subsequently adjusted to reflect the outstanding interest and any remeasurements to the lease liability, including a change in future lease payments arising from a change in rate or index, a change in the Group’s estimate of the amount expected to be payable under a residual guarantee, or if the Group changes its assessment of whether it will exercise a purchase, extension or termination option. When the lease liability is remeasured, a corresponding adjustment is made to the carrying value of the right-of-use asset, or is recorded in the Consolidated Statement of Profit or Loss if the carrying value of the right-of-use asset has been reduced to nil.

The equity securities are not held for trading and are strategic investments for which the Group considers this classification to be more appropriate. Changes in fair value are accumulated in a separate reserve within equity. On derecognition of an equity investment which was elected to be classified at fair value through other comprehensive income, the cumulative gain or loss previously accumulated in the investment’s revaluation reserve is transferred directly to retained earnings. The fair value of the Group’s financial assets at FVOCI is estimated based on quoted market prices at the reporting date and classified as Level 1 on the fair value hierarchy as detailed in Note 23 (d).

Notes to the Financial Statements 23. Financial Instruments and Risk Management The Group is exposed to market, liquidity and credit risk through its financial instruments. The main purpose of these financial instruments is to fund the principal activities of the Group. The Board has overall responsibility for the establishment and oversight of the Group’s risk management framework. The Board meets on a regular basis to analyse exposure and evaluate risk management strategies in the context of the most recent economic conditions and forecasts. The Board has established the Audit and Risk Committee to assist the Board in monitoring and reviewing any matters of significance affecting financial reporting and compliance, including sustainability objectives, environmental and community obligations, ethical standards, codes of conduct and compliance procedures. The Audit and Risk Committee reports regularly to the Board on its activities. The Group’s risk management policies are established to identify and analyse the risks faced by the Group, to set appropriate risk limits and controls and to monitor risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the Group’s activities. The Group, through its training and management standards and procedures, aims to maintain a disciplined and constructive control environment in which all employees understand their roles and obligations. Management is responsible for developing and monitoring the Group’s risk management policies. The Audit and Risk Committee oversees how management monitors compliance with the Group’s risk management policies and procedures and reviews the adequacy of the risk management framework in relation to the risks faced by the Group. Recognition and measurement Initial recognition and measurement Financial assets and financial liabilities are recognised when the Group becomes a party to the contractual provisions to the instrument. For financial assets, this is the date that the Group commits itself to either the purchase or sale of the asset (i.e. trade date accounting is adopted). Financial instruments are initially measured at fair value plus transaction costs, except where the instrument is classified at fair value through profit or loss, in which case transaction costs are expensed to profit or loss immediately. Subsequent measurement (i) Subsequent measurement of financial assets Financial assets are subsequently measured at amortised cost. Measurement is based on two primary criteria: • the contractual cash flow characteristics of the financial asset; and • the business model for managing the financial assets. A financial asset that meets the following conditions is subsequently measured at amortised cost: • the financial asset is managed solely to collect contractual cash flows; and • the contractual terms within the financial asset give rise to cash flows that are solely payments of principal and interest on the principal amount outstanding on specified dates. (ii) Subsequent measurement of financial liabilities Financial liabilities are subsequently measured at amortised cost using the effective interest method. The effective interest method is a method of calculating the amortised cost of a debt instrument and allocating interest expense in profit or loss over the relevant period. The effective interest rate is the internal rate of return of the financial asset or liability. That is, the rate that exactly discounts the estimated future cash flows through the expected life of the instrument to the net carrying value at initial recognition. Impairment The Group recognises a loss allowance for expected credit losses, using the simplified approach under AASB 9 Financial Instruments, which requires the recognition of lifetime expected credit loss at all times. Sayona Annual Report 2025 107

Notes to the Financial Statements 23. Financial Instruments and Risk Management (continued) Derecognition Derecognition refers to the removal of a previously recognised financial asset or financial liability from the Consolidated Statement of Financial Position. (i) Derecognition of financial assets A financial asset is derecognised when the holder's contractual rights to its cash flows expire, or the asset is transferred in such a way that all the risks and rewards of ownership are substantially transferred. All of the following criteria need to be satisfied for derecognition of a financial asset: • the right to receive cash flows from the asset has expired or been transferred; • all risk and rewards of ownership of the asset have been substantially transferred; and • the Group no longer controls the asset (i.e. the Group has no practical ability to make a unilateral decision to sell the asset to a third party). On derecognition of a financial asset measured at amortised cost, the difference between the asset's carrying value and the sum of the consideration received and receivable is recognised in profit or loss. (ii) Derecognition of financial liabilities A liability is derecognised when it is extinguished (i.e. when the obligation in the contract is discharged, cancelled or expires). An exchange of an existing financial liability for a new one with substantially modified terms, or a substantial modification to the terms of a financial liability is treated as an extinguishment of the existing liability and recognition of a new financial liability. The difference between the carrying value of the financial liability derecognised and the consideration paid and payable, including any non-cash assets transferred or liabilities assumed, is recognised in profit or loss. (a) Market risk Market risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market prices. Market risk comprises interest rate risk, foreign currency risk, commodity price risk, provisionally priced commodity sales and other price risk, such as equity price risk. The objective of market risk management is to manage market risk exposures to protect profitability and return on assets. (i) Interest rate risk The Group is exposed to interest rate risk on its cash and cash equivalents, other assets and interest bearing liabilities from the possibility that changes in interest rates will affect future cash flows or the fair value of financial instruments. The Group’s net exposure to interest rate risk at the reporting date is as follows: 2025 $’000 2024 $’000 Financial assets Cash and cash equivalents 72,290 90,624 Other assets 16,340 18,530 Financial liabilities Interest bearing liabilities (44,955) – Net exposure 43,675 109,154 Sensitivity analysis The following table demonstrates the sensitivity to a 100 basis point change in interest rates, with all other variables remaining constant: Effect on profit after tax 2025 $’000 Effect on profit after tax 2024 $’000 +100 basis point change in interest rates 306 764 -100 basis point change in interest rates (306) (764) Sayona Annual Report 2025 108

Notes to the Financial Statements 23. Financial Instruments and Risk Management (continued) (a) Market risk (continued) (ii) Foreign currency risk Foreign currency risk is the risk that the fair value or future cash flows of an exposure will fluctuate because of changes in foreign exchange rates. The Group operates internationally and is exposed to foreign currency risk arising from currency movements, primarily in respect of transactions and instruments in Canadian and United States (US) dollars. No derivative financial instruments are employed to mitigate the exposed risks. The Group's net exposure to foreign currency risk (in Australian dollars) at the reporting date is as follows: Canadian dollar risk exposure 2025 $’000 Canadian dollar risk exposure 2024 $’000 US dollar risk exposure 2025 $’000 US dollar risk exposure 2024 $’000 Financial assets Cash and cash equivalents 1 22,637 21,703 6,290 Trade and other receivables – 155 29,012 6,209 Other assets – – 3,880 5,940 Financial liabilities Trade and other payables (2) – (9,305) (6,464) Interest bearing liabilities – – (47,115) (4,546) Other liabilities – – (7,608) (12,007) Net exposure (1) 22,792 (9,433) (4,578) Sensitivity analysis Based on the Group’s net financial assets and liabilities as at 30 June, a weakening of the Australian dollar against these currencies as illustrated in the table below, with all other variables held constant, would have the following effect on the Group’s profit or loss after tax: Effect on profit after tax 2025 $’000 Effect on profit after tax 2024 $’000 5 per cent movement in Canadian dollar – (798) 5 per cent movement in United States dollar 330 160 (iii) Commodity price risk Contracts for the sale and physical delivery of commodities are executed whenever possible on a pricing basis intended to achieve a relevant index target. Where pricing terms deviate from the index, the Group may choose to use derivative commodity contracts to realise the index price. Contracts for the physical delivery of commodities are not typically financial instruments and are not recognised in the Consolidated Statement of Financial Position. (iv) Provisionally priced commodity sales and purchases contracts Provisionally priced sales are those for which price finalisation, referenced to the relevant index and product grade, is outstanding at the reporting date. Provisional pricing mechanisms embedded within these sales have the character of a commodity derivative and are carried at fair value through profit or loss as part of trade receivables or trade creditors. Fair value movements on provisionally priced sale contracts are disclosed as other revenue in the Group’s results. At 30 June 2025, the Group’s exposure to the impact of movements in commodity prices on provisionally invoiced sales related to spodumene concentrate. As at 30 June 2025, the Group had sold two shipments of spodumene concentrate totalling 46,872 dry metric tonnes (dmt) that were provisionally priced (2024: 27,400 dmt). The final price of these sales will be determined between July 2025 and October 2025. A 10 per cent change in the realised price of the commodity, with all other factors held constant, would increase or decrease profit or loss after tax by $4.6 million (2024: $2.5 million).

Notes to the Financial Statements 23. Financial Instruments and Risk Management (continued) (b) Liquidity risk Liquidity risk is the risk that the Group may not be able to settle or meet its obligations as they fall due. This risk is managed by ensuring, to the extent possible, that there is sufficient liquidity in place, without incurring unacceptable losses or risking damage to the Group's reputation. The entities in the Group are funded by a combination of cash generated by the Group’s operations, long-term funding and intercompany loans provided by the Group. Long-term funding is primarily through equity sources. Financial asset and financial liability maturity analysis The following table shows an undiscounted contractual maturity analysis for financial assets and financial liabilities and reflects management's expectations with respect to realisation of financial assets and financial liabilities and timing of termination: Year ended 30 June 2025 Weighted average interest rate % 1 year or less $’000 1 to 5 years $’000 More than 5 years $’000 Total $’000 Financial assets Cash and cash equivalents 3.49% 72,290 – – 72,290 Trade and other receivables 23,451 – – 23,451 Other financial assets – – 1,007 1,007 Other assets 2.14% 5,389 670 10,281 16,340 Total financial assets 101,130 670 11,288 113,088 Financial liabilities Trade and other payables 49,608 – – 49,608 Interest bearing liabilities 16.00% 15,243 14,675 – 29,918 Lease liabilities 9.63% 2,697 90 – 2,787 Total financial liabilities 67,548 14,765 – 82,313 Net financial instruments 33,582 (14,095) 11,288 30,775 Year ended 30 June 2024 Financial assets Cash and cash equivalents 4.34% 90,624 – – 90,624 Trade and other receivables 11,877 – – 11,877 Other financial assets – – 740 740 Other assets 2.50% 18,530 – – 18,530 Total financial assets 121,031 – 740 121,771 Financial liabilities Trade and other payables 60,876 – – 60,876 Interest bearing liabilities 5.00% 12,672 12,533 – 25,205 Lease liabilities 9.69% 3,200 2,738 – 5,938 Other liabilities – – 4,540 4,540 Total financial liabilities 76,748 15,271 4,540 96,559 Net financial instruments 44,283 (15,271) (3,800) 25,212 (c) Credit risk Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in a financial loss to the Group. Credit risk arises from exposures to deposits with financial institutions, trade and other receivables and deposits. Management monitors credit risk by actively assessing the rating quality and liquidity of counterparties. The Group’s exposure to credit risk is concentrated, as sales are made to a limited number of customers. Accordingly, exposure to credit risk is influenced mainly by the individual characteristics of each customer. Mitigation methods are defined and implemented for counterparties to protect revenues, with a significant amount of the Group’s sales of physical commodities occurring via secured payment terms including prepayments and letters of credit. The Group's maximum exposure to credit risk at reporting date is $100.0 million (2024: $108.3 million), which includes $72.5 million (2024: $90.8 million) in cash and cash equivalents and other long-term fixed deposits held with major financial institutions with strong credit ratings. Sayona Annual Report 2025 110

Notes to the Financial Statements 23. Financial Instruments and Risk Management (continued) (c) Credit risk (continued) Expected credit losses Impairment allowances are based on a forward-looking expected credit loss model. For trade receivables, the Group uses the simplified approach and recognises impairments based on the lifetime expected credit loss. For other receivables, the Group applies the general approach and recognises impairments based on a twelve-month expected credit loss. Individual customers are assigned an external credit rating, and an expected credit loss rate is calculated accordingly, which takes into account actual credit loss experience. (d) Fair values The Group measures some of its assets and liabilities at fair value on either a recurring or non-recurring basis after initial recognition, depending on the requirements of the applicable Accounting Standard. Fair value is the price the Group would receive to sell an asset or would pay to transfer a liability in an orderly (i.e. unforced) transaction between independent, knowledgeable and willing market participants at the measurement date. The fair value of cash and cash equivalents and non-interest bearing financial assets and liabilities reasonably approximate their carrying values. The aggregate fair values and carrying values of financial assets and liabilities are disclosed in the Consolidated Statement of Financial Position. Fair values are materially in line with carrying values. Fair value measurement The carrying value of financial assets and liabilities measured at fair value is principally calculated based on inputs other than quoted prices that are observable for these financial assets or liabilities, either directly (i.e. as unquoted prices) or indirectly (i.e. derived from prices). Where no price information is available from a quoted market source, alternative market mechanisms or recent comparable transactions, fair value is estimated based on the Group’s views on relevant future prices, net of valuation allowances to accommodate liquidity, modelling and other risks implicit in such estimates. The Group applies the following hierarchy for financial assets and liabilities carried at fair value: Fair value hierarchy Valuation inputs Level 1 Based on unadjusted quoted prices in active markets for identical financial assets and liabilities. Level 2 Based on inputs other than quoted prices included within Level 1 that are observable for the financial asset or liability, either directly (i.e. as unquoted prices) or indirectly (i.e. derived from prices). Level 3 Based on inputs not observable in the market using appropriate valuation models, including discounted cash flow modelling. The following table shows the fair value of financial assets and financial liabilities, including their levels in the fair value hierarchy. It does not include fair value information of financial assets and financial liabilities not measured at fair value if the carrying amount is a reasonable approximation of fair value. At 30 June 2025 Level 1 $’000 Level 2 $’000 Level 3 $’000 Total $’000 Other financial assets designated at FVOCI 1,007 – – 1,007 Trade and other receivables – 157 – 157 Total 1,007 157 – 1,164 At 30 June 2024 Other financial assets designated at FVOCI 740 – – 740 Trade and other payables – (6,505) – (6,505) Total 740 (6,505) – (5,765) Sayona Annual Report 2025 111

Notes to the Financial Statements 23. Financial Instruments and Risk Management (continued) (d) Fair values (continued) The following table shows the valuation techniques used in measuring Level 2 fair values for financial instruments in the Consolidated Statement of Financial Position, as well as the significant unobservable inputs used: Type Valuation technique Significant unobservable inputs Inter-relationship between significant unobservable inputs and fair value measurement Other receivables – provisional pricing adjustments Market-based pricing Market-based pricing indices The estimated fair value would decrease (increase) if the market-based pricing were lower (higher). Other payables – provisional pricing adjustments Market-based pricing Market-based pricing indices The estimated fair value would increase (decrease) if the market-based pricing were lower (higher). For financial instruments carried at fair value on a recurring basis, the Group determines whether transfers have occurred between levels in the fair value hierarchy by reassessing categorisation at the end of each reporting period. There were no transfers between levels of the hierarchy during the year. (e) Changes in liabilities from financing activities The movement in the Group’s liabilities from financing activities during the year is as follows: Year ended 30 June 2025 Interest bearing liabilities $’000 Preference shares $’000 Lease liabilities $’000 Total $’000 At the beginning of the financial year – 25,205 5,415 30,620 Cash movements 558 – (3,226) (2,668) Other non-cash movements 24 4,145 475 4,644 At the end of the financial year 582 29,350 2,664 32,596 Year ended 30 June 2024 At the beginning of the financial year 112 24,849 6,253 31,214 Cash movements (112) – (3,280) (3,392) Other non-cash movements – 356 2,442 2,798 At the end of the financial year – 25,205 5,415 30,620 Sayona Annual Report 2025 112

Notes to the Financial Statements 24. Share Capital Ordinary shares Ordinary shares are classified as equity. Transaction costs (net of tax, where the deduction can be utilised) arising on the issue of ordinary shares are recognised in equity as a reduction of the share proceeds received. Where share application monies have been received but the shares have not been issued, these monies are shown as a payable in the Consolidated Statement of Financial Position. The movement in fully paid ordinary shares during the year is as follows: 2025 No. shares 2024 No. shares 2025 $’000 2024 $’000 Share capital At the beginning of the financial year 10,293,296,014 10,039,138,024 795,773 756,744 Shares issued 1,250,000,000 244,157,990 40,000 37,399 Transaction costs associated with share issues – – (2,055) (120) Transfers and other movements (1) (250,000,000) 10,000,000 – 1,750 At the end of the financial year 11,293,296,014 10,293,296,014 833,718 795,773 Treasury shares At the beginning of the financial year – – – – Shares purchased by Employee Share Plan Trustee – – – – Employee share awards vested – – – – Transfers and other movements (1) 250,000,000 – – – At the end of the financial year 250,000,000 – – – (1) On 29 October 2019, the Company entered into an At-the-Market Subscription Agreement (ATM) (previously referred to as a Controlled Placement Agreement) with Acuity Capital. As security for the ATM, Acuity Capital held 250,000,000 ordinary fully paid shares in Sayona Mining Limited (“Collateral Shares”). On 6 January 2025, the Group announced the termination of the ATM, with the Collateral Shares transferred at zero cost from Acuity Capital to the Company’s Employee Share Plan Trustee, where they will be held to meet the future vesting of employee share awards. Ordinary shares participate in dividends and the proceeds on winding up of the parent entity in proportion to the number of shares held. At shareholders' meetings, each ordinary share is entitled to one vote when a poll is called, otherwise each shareholder has one vote on a show of hands. The Company does not have authorised capital or par value in respect of its issued shares. (a) Significant share issues during the year On 29 November 2024, the Group completed a fully underwritten placement to institutional investors, resulting in the issuance of 1,250,000,000 fully paid ordinary shares at an issue price of $0.032 per share for aggregate gross proceeds of $40.0 million. Options Options are classified as equity and issue proceeds are taken up in the share based payments reserve. Transaction costs (net of tax, where the deduction can be utilised) arising on the issue of options are recognised in equity as a reduction of the option proceeds received. The movement in options during the year is as follows: Unlisted options 2025 No. options 2024 No. options At the beginning of the financial year 12,234,482 42,234,482 Granted during the year – 10,000,000 Exercised during the year – (40,000,000) Forfeited / lapsed during the year (10,000,000) – At the end of the financial year 2,234,482 12,234,482 Capital management policy The Group has been funded predominantly by equity up to the date of this report. Management controls the capital of the Group with the aim of creating long-term shareholder value and ensuring the Group can fund its operations and continue as a going concern. The Group’s capital is managed by assessing the Group’s financial risks and adjusting its capital structure in response to changes in these risks and market conditions. None of the Group’s entities are currently subject to externally imposed capital requirements. In addition, there were no changes in the Group’s approach to capital management during the year.

Notes to the Financial Statements Group and Related Party Information This section contains information on the structure and related parties of the Group and how it affects the financial performance and position of the Group. 26. Subsidiaries Subsidiaries are entities controlled by the Company. Control exists where the Company is exposed or has rights to variable returns from its involvement with the subsidiary and has the ability to affect those returns through its power over the subsidiary. The Company has power over the subsidiary when it has existing rights to direct the relevant activities of the subsidiary which are those which significantly affect the subsidiary’s returns. The financial statements of subsidiaries are included in the consolidated financial statements for the period they are controlled. The subsidiaries of the Group at the reporting date are as follows: Ownership interest Subsidiaries Country of incorporation Principal activity 2025 % 2024 % 9474-9454 Québec Inc.

The price paid by Piedmont for the supply of spodumene concentrate is equivalent to an average CIF China market price (in United States dollars) for 6.0 per cent Li2O spodumene concentrate on a dry basis, with a minimum price of US$500 per tonne and a maximum price of US$900 per tonne on a delivered basis. The term of the Agreement is the life of mine of North American Lithium.

Notes to the Financial Statements 30. Share Based Payments (continued) (a) Description of share based payment arrangements Employee Share and Option Plan On 16 November 2022, the Group established an Employee Share and Option Plan which enables the grant of equity rights and options to key management personnel, senior management and other eligible employees. Invitation to participate in the plan is at the absolute discretion of the Board. The key terms and conditions related to grants under the plan are as follows: • the Board retains discretion to make decisions on the plan and set or amend terms and conditions; and • the vesting of equity rights and options will be conditional on the satisfaction of all vesting conditions attaching to the equity rights and options. (i) Recurring share based payment arrangements The equity awards listed below are subject to the general conditions noted above and may be granted annually, subject to approval by shareholders at the Annual General Meeting for awards to the Managing Director and Chief Executive Officer and by the Board of Directors for all other awards to eligible employees. Deferred Short-Term Incentive Plan The Deferred Short-Term Incentive Plan is the Group’s short-term incentive plan for the Executive Leadership Team and other eligible employees below the Executive Leadership Team. Awards are granted annually to eligible employees. Awards granted under the FY24 Deferred Short-Term Incentive Plan and FY25 Deferred Short-Term Incentive Plan will vest in October 2025 and October 2026 respectively, subject to participants remaining employed by the Group. Long-Term Incentive Plan The Long-Term Incentive Plan is the Group’s long-term incentive plan for the Executive Leadership Team and other eligible employees below the Executive Leadership Team. Awards are granted annually to eligible employees. Awards granted under the FY25 Long-Term Incentive Plan are subject to performance and service conditions being satisfied over a three (3) year measurement period from 1 July 2024 to 30 June 2027, with vesting to occur at the end of the measurement period. Employee Share Plan The Employee Share Plan is the Group’s share plan for employees not eligible to participate in the Deferred Short-Term Incentive Plan or Long-Term Incentive Plan. Awards are granted annually to eligible employees. Awards granted under the FY25 Employee Share Plan will vest over two tranches in January 2026 and January 2027 respectively, subject to participants remaining employed by the Group. (ii) Transitional share based payment arrangements The equity awards listed below are subject to the general conditions noted above and are either one-off or will not be granted on an ongoing basis. Transitional Management Incentive Plan The Transitional Management Incentive Plan is a one-off grant made to eligible employees to satisfy contractual employment obligations in place prior to implementation of the recurring share based payment arrangements noted above. Awards granted under the FY24 Transitional Management Incentive Plan will vest over two tranches in January 2026 and March 2026 respectively, subject to participants remaining employed by the Group. (b) Employee Share Plan Trust The Sayona Mining Limited Employee Share Plan Trust (the Trust) is a discretionary trust for the benefit of employees of Sayona Mining Limited and its subsidiaries. The trustee of the Trust (CPU Share Plans Pty Limited) is an independent company, resident in Australia. Generally, the Trust uses funds provided by Sayona Mining Limited to acquire shares to enable awards to be made or satisfied under the Group’s employee share plans. Shares may be acquired by purchase in the market or by subscription at no less than market value on the date on which the shares are issued to the trustee. Sayona Annual Report 2025 118

Notes to the Financial Statements 30. Share Based Payments (continued) (c) Measurement of fair values Share based payments to employees are measured at the fair value of the instruments issued. Share based payments to non-employees are measured at the fair value of goods or services received or the fair value of the equity instruments issued if the fair value of the goods or services received cannot be reliably measured, and are recorded at the date the goods or services are received. The fair value at grant date of equity-settled share awards is charged to the Consolidated Statement of Profit or Loss, net of tax, over the period for which the benefits of employee services are expected to be derived. The corresponding accrued employee entitlement is recorded in the share based payments reserve. Where awards are forfeited because non-market-based vesting conditions are not satisfied, the expense previously recognised is proportionally reversed. If awards do not vest due to a market-based performance condition not being met, the expense is recognised in full and the share based payments reserve is released to retained earnings. Where shares in Sayona Mining Limited are acquired by on-market purchases prior to settling the vested entitlement, the cost of the acquired shares is carried as treasury shares and deducted from equity. Where awards are satisfied by delivery of acquired shares, any difference between their acquisition cost and the cumulative remuneration expense recognised is charged directly to retained earnings, net of tax. The fair value of retention and other non-market-based equity rights (i.e. Deferred Short-Term Incentive Plan, Employee Share Plan, Transitional Management Incentive Plan, and equity-settled services) is measured using the Black Scholes methodology, which is based on the Black-Scholes-Merton model. This methodology considers the following: • Expected life of the award; • Current market price of the underlying shares; • Expected volatility; • Expected dividends; and • Risk-free interest rate. The fair value of market-based equity rights (i.e. Long-Term Incentive Plan) is measured using the Monte Carlo methodology, which is based on the Binomial Option Pricing model. This methodology considers the following: • Expected life of the award; • Current market price of the underlying shares; • Expected volatility (of the individual company and each peer group); • Expected dividends; • Risk-free interest rate; and • Market-based performance hurdles. The expected volatility for all rights issued is based on the historical share price volatility of the Group at each respective grant date. The inputs used in the measurement of the fair values at grant date of the Group’s share based payment arrangements were as follows: Year ended 30 June 2025 Fair value at grant date $ Share price at grant date $ Expected volatility % Expected Life (in years) Risk-free interest rate based on government bonds % Recurring FY24 Deferred Short-Term Incentive Plan 0.0320 0.0320 85 0.92 4.145 FY25 Deferred Short-Term Incentive Plan 0.0320 0.0320 80 1.92 3.957 FY25 Employee Share Plan 0.0270 0.0270 80 1.00 – 2.00 3.849 – 4.002 FY25 Long-Term Incentive Plan 0.0263 0.0320 80 2.76 3.923 Non-recurring FY24 Transitional Management Incentive Plan 0.0270 0.0270 80 1.00 – 1.25 3.937 – 4.002 Sayona Annual Report 2025 119

Notes to the Financial Statements 34. Restatement of Comparative Information Adjustment to earnings per share upon termination of facility with Acuity Capital On 29 October 2019, the Company entered into an At-the-Market Subscription Agreement (ATM) (previously referred to as a Controlled Placement Agreement) with Acuity Capital. The ATM provided the Group with up to $200 million of standby equity capital. As security for the ATM, Acuity Capital held 250,000,000 ordinary fully paid shares in Sayona Mining Limited (“Collateral Shares”). On 6 January 2025, the Group announced the termination of the ATM, with the Collateral Shares transferred at zero cost from Acuity Capital to the Company’s Employee Share Scheme Trustee, where they will be held to meet the future vesting of employee share awards. Upon termination of the facility, the Group conducted a review of its reporting obligations and identified the need to retrospectively adjust the calculation of earnings per share for the year ended 30 June 2024 to exclude the shares which have been transferred to the Company’s Employee Share Scheme Trustee from the total weighted average number of ordinary shares in accordance with AASB 133 Earnings per Share. The following table shows the impact of the adjustment on the weighted average number of ordinary shares and earnings per share calculations for the year ended 30 June 2024: Reported balance Adjustment Restated balance Weighted average number of ordinary shares (‘000) Basic earnings per share denominator 10,277,968 (250,000) 10,027,968 Ordinary share contingently issuable – – – Diluted earnings per share denominator 10,277,968 (250,000) 10,027,968 Earnings per share (cents) Basic (0.99) (0.02) (1.01) Diluted (0.99) (0.02) (1.01) 35. Subsequent Events The following events have arisen since the end of the reporting period: Merger between Sayona Mining Limited and Piedmont Lithium Inc. On 18 November 2024, Sayona Mining Limited, Shock MergeCo Inc., a wholly owned subsidiary of Sayona (“Merger Sub”), and Piedmont Lithium Inc. entered into a Merger Agreement to combine Sayona and Piedmont. The merger was approved by Sayona shareholders at the Company's Extraordinary General Meeting on 31 July 2025. Piedmont stockholders subsequently approved the merger at their Special Meeting on 23 August 2025 (Australian time). As such, subject to satisfaction of the remaining conditions, completion of the merger is scheduled to take place on 30 August 2025. Following completion of the merger, Piedmont Lithium Inc. will become a wholly owned subsidiary of Sayona, with Sayona being the surviving entity with a primary listing on the ASX and a secondary listing on the Nasdaq. Conditional placement to Resource Capital Fund VIII L.P. On 19 November 2024, the Group entered into a Subscription Agreement with Resource Capital Fund VIII L.P. (RCF) to raise approximately $69 million (before costs) through the issue of 2,156,250,000 ordinary shares in Sayona Mining Limited at an issue price of $0.0320 per ordinary share, subject to completion of the proposed merger with Piedmont Lithium Inc. (“Conditional Placement”). On 31 July 2025, Sayona shareholders approved the Conditional Placement to RCF. On 12 August 2025, the Company and RCF agreed to extend the Subscription Agreement until 31 December 2025. As part of the extension, RCF agreed to subscribe to a further 1,200,000,000 options (“New Options”) to be issued in two tranches: • The first tranche of options to be issued shall be such number of options that results in RCF holding a 9.99 per cent interest in the issued share capital of the Company (Tranche 1 Options); and • Subject to obtaining all applicable regulatory approvals, the second tranche of options to be issued shall be such number of options that is 1,200,000,000 less the Tranche 1 Options (Tranche 2 Options). The exercise price of the New Options is $0.0320, a 14 per cent premium to the closing share price on 11 August 2025 and the same price as the issue price under the Conditional Placement, and within the Company’s existing placement capacity under ASX Listing Rule 7.1. If all New Options are exercised in full, the total value of the placement will be approximately $38 million. No other matters or circumstances have arisen since the end of the reporting period that have significantly affected or may significantly affect the operations, results of operations or state of affairs of the Group in subsequent periods.

Independent Auditor’s Report to the members of Sayona Mining Limited Report on the audit of the financial report Opinion We have audited the financial report of Sayona Mining Limited (the Company) and its subsidiaries (collectively the Group), which comprises the consolidated statement of financial position as at 30 June 2025, the consolidated statement of comprehensive income, consolidated statement of changes in equity and consolidated statement of cash flows for the year then ended, notes to the financial statements, including material accounting policy information, the consolidated entity disclosure statement and the directors’ declaration.

Giving a true and fair view of the consolidated financial position of the Group as at 30 June 2025 and of its consolidated financial performance for the year ended on that date; and b. Complying with Australian Accounting Standards and the Corporations Regulations 2001. Basis for opinion We conducted our audit in accordance with Australian Auditing Standards. Our responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the financial report section of our report. We are independent of the Group in accordance with the auditor independence requirements of the Corporations Act 2001 and the ethical requirements of the Accounting Professional and Ethical Standards Board’s APES 110 Code of Ethics for Professional Accountants (including Independence Standards) (the Code) that are relevant to our audit of the financial report in Australia. We have also fulfilled our other ethical responsibilities in accordance with the Code. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. Key audit matters Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial report of the current year. These matters were addressed in the context of our audit of the financial report as a whole, and in forming our opinion thereon, but we do not provide a separate opinion on these matters. For each matter below, our description of how our audit addressed the matter is provided in that context. We have fulfilled the responsibilities described in the Auditor’s responsibilities for the audit of the financial report section of our report, including in relation to these matters. Accordingly, our audit included the performance of procedures designed to respond to our assessment of the risks of material misstatement of the financial report. The results of our audit procedures, including the procedures performed to address the matters below, provide the basis for our audit opinion on the accompanying financial report.

Impairment of North American Lithium Why significant How our audit addressed the key audit matter At 30 June 2025 the Group recognised a total before-tax impairment charge of $271.3 million in respect of its North American Lithium (“NAL”) cash generating unit (“CGU”). Australian Accounting Standards require the Group to assess, at the end of each reporting period, whether there is any indication that an asset or CGU may be impaired. If any such indication exists an entity shall estimate the recoverable amount of the asset or CGU. The Group determined impairment indicators existed at 30 June 2025 and undertook impairment testing for its CGUs. NAL’s recoverable amount was estimated using a discounted cash flow model. Forecasting cashflows involves accounting estimates and judgements and is affected by expected future performance and market conditions. The key forecast assumptions used in the Group’s impairment assessment, include commodity prices, foreign exchange rates, discount rates and future production are set out in in Note 14 to the financial report. We considered the impairment testing of the NAL CGU, the associated impairment charge and the related disclosures in the financial report to be a key audit matter. Impairment testing of North American Lithium We assessed the forecast cash flows and the reasonableness of key estimates, inputs and assumptions impacting the Group’s calculated recoverable amount. In conjunction with our valuation specialists, our procedures included: • Testing the mathematical accuracy of the discounted cash flow model. • Independently developing a reasonable range of forecast commodity prices and foreign exchange rates, based on a variety of reputable third-party forecasts and market data. We compared this range to the Group’s forecast commodity price and foreign exchange assumptions, to assess whether the Group’s assumptions were reasonable. • Independently developing a range of reasonable discount rates to assess whether the Group’s weight average cost of capital (“WACC”) applied to the NAL CGU was reasonable. • Analysing forecast operating and capital cost assumptions against historical performance, latest approved budgets and forecasts, long term asset plans and other information obtained throughout the audit. This included consideration of future production profiles, detailed below. • Considering the sensitivity of NAL’s recoverable amount to changes in key inputs, such as alternative spodumene prices and discount rates. Future production profiles An input to impairment assessment is NAL’s production forecasts, and its ore reserves and resources quantities. Our audit procedures considered the work of the Group’s external experts and included: • Reading the latest reserves and resources estimates. • Assessing the competence, capability and objectivity of the Group’s external experts involved in the estimation process and assessing their scope of work and methodology applied. • Understanding the reasons for changes in reserves and resources or the absence of changes, for consistency with other information that we obtained throughout the audit. • Reconciling future production profiles, to the latest reserves and resources estimates, current approved development budgets and historical operations. Disclosures in the financial report Assessed the adequacy of the disclosures in Note 14 to the financial report. Sayona Annual Report 2025 127

Auditor’s responsibilities for the audit of the financial report Our objectives are to obtain reasonable assurance about whether the financial report as a whole is free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the Australian Auditing Standards will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of this financial report. As part of an audit in accordance with the Australian Auditing Standards, we exercise professional judgment and maintain professional scepticism throughout the audit. We also: • Identify and assess the risks of material misstatement of the financial report, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. • Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group’s internal control. • Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the directors. • Conclude on the appropriateness of the directors’ use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the financial report or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Group to cease to continue as a going concern. • Evaluate the overall presentation, structure and content of the financial report, including the disclosures, and whether the financial report represents the underlying transactions and events in a manner that achieves fair presentation. • Plan and perform the Group audit to obtain sufficient appropriate audit evidence regarding the financial information of the entities or business units within the Group as a basis for forming an opinion on the Group financial report. We are responsible for the direction, supervision and review of the audit work performed for the purposes of the Group audit. We remain solely responsible for our audit opinion. We communicate with the directors regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit. We also provide the directors with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, actions taken to eliminate threats or safeguards applied. From the matters communicated to the directors, we determine those matters that were of most significance in the audit of the financial report of the current year and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

Mineral Resources and Ore Reserves Overview The Group reports Mineral Resources and Ore Reserves in accordance with the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code), as required by Chapter 5 of the Australian Securities Exchange (ASX) Listing Rules. Mineral Resources and Ore Reserves are reported in 100 per cent terms and represent estimates as at 30 June 2025. Our Mineral Resource estimations include Measured and Indicated Mineral Resources which, after the application of all Modifying Factors and development of a mine plan, have been classified as Ore Reserves. All quantities in this Mineral Resources and Ore Reserves section are reported in dry metric tonnes, unless otherwise stated. It is important to note that Mineral Resources and Ore Reserves are estimations, not precise calculations. Tonnes and grade data may have been rounded to reflect the relative uncertainty of the estimate, which is why minor computational differences may be present in the totals. Commodity price and exchange rate assumptions used to estimate the economic viability of Ore Reserves are based on internal and external studies and long-range forecasts. Our planning processes consider a range of impacts on Ore Reserves, including assessments of operating cost and the expectation of economically viable extraction. All Ore Reserves reported are within existing permitted mining tenements. Our mineral leases are of sufficient duration, or convey a legal right to renew the tenure, to enable Ore Reserves on the leased properties to be mined in accordance with forecasted production schedules. These Ore Reserves may include areas where additional approvals are required, and it is expected that such approvals will be obtained within the timeframe needed to meet the forecasted production schedule. Competent Persons Information in this Mineral Resources and Ore Reserves section relating to Exploration Targets, Exploration Results, Mineral Resources or Ore Reserves is based on, and fairly represents, information and supporting documentation compiled by the Competent Persons listed in the table below, which includes details on their respective professional association, relationship to Sayona, and the area for which each Competent Person is taking responsibility. A Competent Person is defined in the JORC Code. They must have a minimum of five years’ experience working with the style of mineralisation or type of deposit under consideration and relevant to the activity being undertaken. Each of our Competent Persons has given consent to the inclusion of the information in this Mineral Resources and Ore Reserves section in the form and context in which it appears.

IFRS (International Financial Reporting Standards) Accounting standards as issued by the International Accounting Standards Board (IASB). Indicated Mineral Resource That part of a Mineral Resource for which quantity, grade (or quality), densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes, and is sufficient to assume geological and grade (or quality) continuity between points of observation where data and samples are gathered. An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Ore Reserve (JORC Code). Sayona Annual Report 2025 142

Inferred Mineral Resource That part of a Mineral Resource for which quantity and grade (or quality) are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade (or quality) continuity. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to an Ore Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. (JORC Code).

Geological evidence is derived from detailed and reliable exploration, sampling and testing gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes, and is sufficient to confirm geological and grade (or quality) continuity between points of observation where data and samples are gathered. A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proved Ore Reserve or, under certain circumstances, a Probable Ore Reserve (JORC Code). MERN Ministere de I’Energie et des Ressources Naturelles. Mineral Reserve The economically mineable part of a Measured Mineral Resource or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at pre-feasibility or feasibility level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified. Mineral Resource 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. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories (JORC Code). Mineralisation Any single mineral or combination of minerals occurring in a mass or deposit of economic interest. The term is intended to cover all forms in which mineralisation might occur, whether by class of deposit, mode of occurrence, genesis or composition (JORC Code). Mining All activities related to the extraction of metals, minerals and gemstones from the earth, whether surface or underground, and by any method. Modifying Factors Considerations used to convert Mineral Resources to Ore Reserves including, but not limited to, mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors (JORC Code).

NAL North American Lithium. NASDAQ The NASDAQ (National Association of Securities Dealers Automated Quotations) is a global electronic marketplace for trading securities, most notably stocks. It’s the second-largest stock exchange in the world by market capitalisation and is known for its concentration of technology companies. While often used to refer to the exchange, Nasdaq, Inc. is the parent company that owns and operates the NASDAQ stock exchange along with other exchanges and financial services. NSR (Net Smelter Return) Revenue derived from the sale of products and concentrates following the application of metallurgical recoveries, less any allowable deductions such as transport costs, treatment charges, refining charges, penalties, freight and royalties. NPV Net present value. Open Pit Surface mining activity in which the working area is kept open to the sky. Ore Reserve The economically mineable part of a Measured Mineral Resource or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at pre-feasibility or feasibility level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified (JORC Code). OTCQB OTCQB Venture Market. Piedmont Piedmont Lithium Inc. and its controlled entities, unless otherwise stated. Probable Ore Reserve The economically mineable part of an Indicated and, in some circumstances, a Measured Mineral Resource. The confidence in the Modifying Factors applying to a Probable Ore Reserve is lower than that applying to a Proved Ore Reserve (JORC Code). Proved Ore Reserve The economically mineable part of a Measured Mineral Resource. A Proved Ore Reserve implies a high degree of confidence in the Modifying Factors (JORC Code). QST Québec Sales Tax. Recovery The percentage of material of interest that is extracted during mining or processing; a measure of mining or processing efficiency. Reserve Life The period in which Total Ore Reserves are expected to be extracted through planned mining activities. ROM (Run of Mine) Product mined in the course of regular mining activities. Tonnes include allowances for diluting materials and for losses that occur when the material is mined. S&P Standard and Poor’s. SASB (Sustainability Accounting Standards Board) A non-profit organisation that develops standards focused on the financial impacts of sustainability. Sayona Sayona Mining Limited and its controlled entities, unless otherwise stated. STI Short-term incentive. Stockpile An accumulation of ore or mineral built up when demand slackens or when the treatment plant or beneficiation equipment is incomplete or temporarily unable to process the mine output; any heap of material formed to create a buffer for loading or other purposes, or material dug and piled for future use. Surface Water All water naturally open to the atmosphere including rivers, lakes, creeks and external water dams but excluding water from oceans, seas and estuaries (e.g. precipitation and runoff including snow and hail). Sustainable Development Activity that supports the needs of the present without compromising the ability of future generations to meet their own needs. Tailings The portions of washed or milled ore that are too poor to be treated further, or remain after the required metals and minerals have been extracted. TCFD Task Force on Climate-Related Financial Disclosures. TNFD Task Force on Nature-Related Financial Disclosures. Total Mineral Resources The sum of Measured Mineral Resources, Indicated Mineral Resources and Inferred Mineral Resources. Total Ore Reserves The sum of Proved Ore Reserves and Probable Ore Reserves. TRIFR (Total Recordable Injury Frequency Rate) The sum of recordable injuries multiplied by 1,000,000, divided by exposure hours for employees and contractors. TRIFR is stated in units per one million hours worked, unless specified otherwise. Sayona Annual Report 2025 144

TSM (Towards Sustainable Mining) A globally recognised performance system that helps mining companies evaluate and manage their environmental and social responsibilities. TSR (Total Shareholder Return) The return delivered to shareholders over a certain period through the change in share price and any dividends paid. TSX Toronto Stock Exchange. Underground Underground mining activity in which the working area is below the surface of the earth. Underlying Depreciation and Amortisation Expense Underlying depreciation and amortisation expense including depreciation and amortisation and non-cash inventory movements. Underlying EBITDA Profit before net financial income and expenses, income tax expense, other earnings adjustment items, depreciation and amortisation expense. Undue Barriers A situation of cumulative and dynamic inequality resulting from workplace interactions, practices, decisions or behaviours, whether individual or institutional, that have adverse effects, intended or unintended, on members of groups covered by section 10 of the Charter of Rights and Freedoms.
