Highlights Finalization of agreements and establishment of a strategic supply and marketing framework with the Government of Canada translating into a long-term take-or-pay agreements covering 30ktpy of flake graphite to be produced at the Matawinie mine. The marketing structure allows NMG to market the Government of Canada’s committed volumes with an upside-sharing mechanism on proceeds above a fixed price, and the ability for Canada to store product. On May 15, 2026, the Company completed for the Phase 2 Matawinie Mine a private placement with strategic investors for aggregate gross proceeds of C$295 million (US$213M). In addition, aggregate gross proceeds of C$132 million (US$97M) from the Company’s subscription receipts issued on April 16, 2026, were released upon satisfaction of the applicable escrow release conditions. These transactions formed part of an aggregate equity financing package of C$427 million (US$310M). The participation of Eni S.p.A., NMG’s new strategic investor, in the private placement was complemented by a letter of intent to advance commercial discussions toward a potential 15ktpy graphite concentrate offtake from the Phase 2 Matawinie Mine or equivalent in active anode material. Following this successful private placement and the previously announced debt financing commitment of US$335 million, NMG confirmed the FID for the Phase 2 Matawinie Mine and officially launched construction. The Company recently completed a Class 3 AACE cost estimate for the development of the 13ktpy Bécancour Battery Material Plant, with an estimated CAPEX of C$374 million (US$267M). In addition, it is pursuing the advancement of engineering and accelerating due diligence processes of its various stakeholders in support of a targeted FID in H2 2026. Twelve-month rolling Total Recordable Injury Frequency Rate (TRIFR) of 0.95 for the Company’s employees and 0 for the contractors active at the Matawinie mine construction site and no major environmental incidents as of June 30, 2026. Looking ahead, NMG remains focused on the next phase of execution across its integrated business model which includes, amongst others, pursuing the civil works at the Matawinie site, continuing to advance the conditions required to support a targeted FID for its 13ktpy Bécancour Battery Material Plant and pursuing ongoing business development. Period-end cash position of C$461 million. MONTRÉAL, August 13, 2026--(BUSINESS WIRE)--Nouveau Monde Graphite Inc. ("NMG" or the "Company") (NYSE : NMG, TSX : NOU) provides a quarterly update on its financial and operational performance and strategic progress for the second quarter ended June 30, 2026. Aligned with its strategy to develop one of the first fully integrated natural graphite production platforms in the G7, this second quarter was marked by the Financial Investment Decision (FID) and construction launch of the Matawinie Mine, while the Company also actively continued to advance key activities supporting a targeted FID in H2 2026 for its 13ktpy Bécancour Battery Material plant. "The second quarter of 2026 was a key chapter in NMG’s journey," said Eric Desaulniers, NMG Founder, President and Chief Executive Officer. "With the successful financing and launch of construction activities at the Matawinie Mine, we transitioned from years of planning and development into execution all while remaining focused on advancing the next major development stage for our 13ktpy Bécancour Battery Material Plant. At a time when supply chain security, industrial resilience and strategic autonomy have become key priorities, these milestones reflect the dedication of our team, the confidence of our partners and shareholders, and the continued strategic importance of NMG’s integrated graphite operations in Western markets. The momentum from the second quarter is carrying us into our next stage of growth, with a clear focus on advancing construction at the Matawinie Mine, securing FID for our 13ktpy Bécancour Battery Material Plant, and continuing to position NMG for the opportunities that lie ahead." Matawinie Mine (Phase 2) In May, following the successful private placement and debt financing commitment, NMG confirmed the FID for the Phase 2 Matawinie Mine and officially launched construction in the presence of federal and provincial leaders, including the Prime Minister of Canada, as well as community representatives, Indigenous partners and industry stakeholders. Since the launch of construction, the Company reports ongoing progress at the Matawinie Mine, with activities remaining within the overall budget. As of June 30, 2026, C$33 million had been incurred in project expenditures and C$167 million had been committed, reflecting ongoing construction, engineering, procurement and project execution activities. Primary focus has been on civil works, with first concrete pours undertaken in July 2026. Key activities also included excavation for the concentrator and associated infrastructure at the industrial platform, excavation of water control structures, backfill of material into the overburden and organic stockpiles, continued advancement of detailed engineering and procurement of key equipment and construction packages and initiation of deposits on critical long-lead equipments. In addition, the amendment to Decree 47-2021 for the Matawinie Mine (Phase 2) was officially published on August 5, 2026. It updates the initial government authorization issued in 2021 to reflect the project's evolution since then. This amendment primarily relates to certain operational parameters of the project, including a minor southward extension of the open pit made possible through the acquisition of additional surface rights, and the corresponding increase in the authorized annual graphite production capacity from 100,000 tonnes to 106,000 tonnes. 13ktpy Bécancour Battery Material Plant The Company recently completed a Class 3 AACE cost estimate for the development of the 13ktpy Bécancour Battery Material Plant, with an estimated CAPEX of C$374 million (US$267M). In addition, it is pursuing the advancement of engineering and accelerating due diligence processes of its various stakeholders in support of a targeted FID in H2 2026. Panasonic Energy has reiterated its intent to support the development of NMG’s Phase 2 facility, which may entail an equity investment by Panasonic at the FID of the Phase 2 13ktpy Bécancour Battery Material Plant, in line with Panasonic’s initial investment in 2024. To support customer demand, NMG also continues various workstreams to develop Additional Battery Material Plants of active anode material and/or advanced graphite materials production that could be developed on its existing 200,000-m² adjacent greenfield or other strategically positioned sites either in North America or in Europe. Near-term priorities Looking ahead, NMG remains focused on the next phase of execution across its integrated business model. Key priorities include: pursuing civil works at the Matawinie site, pouring of concrete foundations for major equipment and building foundations in advance of the installation of structural steel in early 2027; continuing to advance the conditions required to support a targeted FID for its 13ktpy Bécancour Battery Material Plant in H2 2026, including the optimization of the capital structure; pursuing ongoing business development, including securing additional offtake agreements and diversifying NMG’s mix of products. Alongside these priorities, the Company will continue to actively engage with customers, shareholders, investors, government partners, Indigenous communities and other stakeholders to support, amongst others, commercialization efforts and long-term growth. Planned engagement activities include participation in key industry and investor forums, such as for example the H.C. Wainwright 28th Annual Global Investment Conference (September 14-16) and the Maxim Growth Summit 2026 (October 13-14), as NMG continues to maintain strategic relationships across the critical minerals value chain. Current Business Opportunities The Company has observed growing interest from potential customers seeking to diversify and secure their critical minerals supply chains as they try to navigate the current geopolitical situation, characterized by growing trade frictions between Europe, China and the United States and near-term uncertainty in certain regions of the Middle East and Africa. NMG’s integrated business model, underpinned by low-cost hydropower, the proximity between the mine and the planned transformation asset, and Canada’s and Québec’s established industrial ecosystems, remains a key differentiator. In the near future, the Corporation intends to expand commercial discussions with respect to the 30,000 tonnes of flake graphite expected to be produced at the Matawinie mine and which is currently earmarked for the spot market. Amongst others, it intends to advance commercial discussions with Eni S.p.A towards a potential 15ktpy graphite concentrate offtake or equivalent in active anode material. At the same time, it is also exploring various business opportunities, mainly with customers that are part of the lithium-ion battery supply chain, may it be for electric vehicles or the fast-growing Battery Energy Storage Systems (BESS) market. Notwithstanding the outcome of these specific commercial discussions, the Corporation has also approached other large G7 integrated conglomerates that have investments or investment plans in battery plants making them potential customers for the Corporation’s natural graphite anode material.

("NMG" or the "Company") (NYSE: NMG, TSX: NOU) reports progress on the advancement of its development plan and start of construction activities at the Phase-2 Matawinie Mine. The Company issues its 2025 ESG Report that demonstrates continued stewardship of environmental, social and governance ("ESG") issues aligned with western efforts to secure local and responsible graphite production and international standards as required by lenders, investors, regulators, and customers. Eric Desaulniers, Founder, President, and CEO of NMG, declared: "Team Nouveau Monde is now focused on execution. With financing in place for the Matawinie Mine, we have kickstarted construction for what is projected to be the first and largest ore-to-advanced-graphite-materials production of the G7. This disciplined progress is essential to delivering a responsible, local supply of natural graphite to our customers at a time when supply chain security is becoming increasingly critical. Against a backdrop of evolving market dynamics and trade conditions, the relevance of our value proposition is only strengthening – combining jurisdictional advantage, sustainability, and supply chain resilience." Matawinie Mine NMG secured a comprehensive financing structure for the Phase‑2 Matawinie Mine combining a committed US$335 million debt package with Export Development Canada ("EDC") and the Canada Infrastructure Bank ("CIB"); an aggregate US$213 million private placement with Canada Growth Fund ("CGF"), the Government of Québec, through Investissement Québec ("IQ"), and Eni S.p.A. ("Eni"); and an oversubscribed bought deal public offering for gross proceeds of approximately US$96.5 million. With contemplated total gross proceeds of approximately US$645 million, the financing process is nearing completion. NMG expects to declare a positive final investment decision ("FID") for the Phase-2 Matawinie Mine upon closing of the private placements and the satisfaction of the released conditions of the bought deal public offering following shareholders’ approval. To optimize the project schedule in line with seasonality, NMG initiated construction activities at the Matawinie site in early Q2‑2026. The Company is assisted by an integrated project team ("IPT") composed of Pomerleau as Construction Manager and AtkinsRéalis as Engineering Firm to oversee the execution of the Phase-2 Matawinie Mine. The IPT is now mobilized onsite alongside Manawan-Fournier, the contractor responsible for the main civil works package. The construction site has been prepared and secured; equipment and workers continue to gradually arrive onsite; and civil works advance with a focus on stripping of the industrial platform and environmental infrastructure areas. NMG continues to advance detailed engineering and procurement of key services and equipment to accelerate construction upon reaching a positive FID. Major contracts awarded and secured represent over 50% of the project’s CAPEX and are within estimates of the 2025 Matawinie Mine Feasibility Study. 13-ktpa Bécancour Battery Material Plant With a view to establishing a fully integrated graphite platform, the Company is advancing the retrofit plan of the recently acquired brownfield property for the 13-ktpa Bécancour Battery Material Plant and developing a Class 3 estimate as per AACE Recommended Practice 47R‑11. NMG’s recently acquired brownfield property should enable the Company to lower infrastructure costs, optimize CAPEX per tonne costs for this first stage development, and streamline permitting, engineering, and construction timelines to align the commissioning period with that of the Matawinie Mine. The Company’s procurement strategy is advancing for key technical expertise, specialized equipment, and long-lead items, alongside project financing activities with a view to proceeding with a FID in H2-2026. ESG & Corporate Matters As the Company transitions from planning to execution for its Phase-2 commercial operations, NMG continues to strengthen its intendance of material ESG issues aligning with internationally recognized practices endorsed by potential lenders, institutional investors, regulators, and customers. NMG continued to demonstrate strong ESG performance in 2025, maintaining its carbon neutrality, achieving an industry-leading sustainability ranking, ensuring environmental stewardship, and advancing community and Indigenous engagement and participation. The Company progressed along its ESG roadmap through disciplined governance, a highly engaged workforce (83% engagement), and the integration of sustainability into project execution as it advances toward construction and commercial operations. NMG’s 2025 ESG Report can be consulted on the Company’s website. The Company is committed to the safe and responsible conduct of operations. For the twelve-month rolling period ended March 31, 2026, NMG reported a total recordable injury frequency rate ("TRIFR") of 2.98, and 0 at its worksite, with no major environmental incidents. At the end of the period, the Company had a cash position of $57.3 million. NMG will hold its annual and special meeting of shareholders on May 13, 2026 at 10:00 a.m. EDT via webcast at https://virtual-meetings.tsxtrust.com/en/1931.

The meeting will be complemented with a corporate presentation by Founder, President and CEO Eric Desaulniers providing an update on the Company’s key projects, commercial engagement, and growth plan. Market Trends Global electric vehicle ("EV") sales totaled approximately 4 million units in Q1 2026, down 3% year-over-year, but masking a sharp inflection within the quarter (Benchmark Mineral Intelligence, April 2026). March volumes rebounded strongly as oil prices spiked following the onset of the Iran conflict, with several markets recording double-digit growth (Bloomberg, April 2026). Europe achieved a record month in March with over 500,000 units sold — up 72% month-over-month and 37% year-over-year — supported by government incentives and elevated fuel prices linked to geopolitical tensions in the Middle East. These dynamics underscore the growing linkage between EV adoption and energy security considerations. Global energy storage deployment remains at record levels in 2026, with annual installations expected to reach ~350–360 GWh in 2026, representing continued double-digit growth following the >100 GW milestone achieved in 2025 (Morgan Lewis, March 2026). With a global capacity pipeline of 9,767 GWh across 461 plants by 2030 (Benchmark Mineral Intelligence, April 2026), lithium-ion battery production for transportation and energy storage supports incremental demand for graphite-based materials. Flake graphite prices remained stable into Q1-2026, with limited short-term reaction to downstream demand volatility. In contrast, active anode material pricing continues to reflect premiums associated with product performance, traceability, and security of supply – factors gaining importance amid geopolitical uncertainty and supply chain security (Benchmark Mineral Intelligence, April 2026). Recent policy announcements in the Western World point to increasing coordination on critical mineral supply chains. Governments are advancing measures including investment vehicles, long-term offtake frameworks, and pricing mechanisms aimed at reducing reliance on concentrated processing jurisdictions and securing inputs for EVs, energy storage, and strategic industries. Canada and the European Investment Bank signed a Letter of Intent to explore cooperation on critical raw materials, building on the existing EU-Canada Strategic Partnership on Raw Materials to support secure, sustainable and diversified supply chains for minerals and metals critical to the green and digital transitions (Government of Canada, March 2026). The U.S. and EU signed a memorandum of understanding to secure and co-produce essential minerals used in semiconductors, EVs, and defense technologies (European Commission, April 2026).

Period-end cash position of $61.7 million. MONTRÉAL, November 12, 2025--(BUSINESS WIRE)--Nouveau Monde Graphite Inc. ("NMG" or the "Company") (NYSE: NMG, TSX: NOU) provides an update on its project development, commercialization and financing advancements in view of reaching a final investment decision ("FID") for its natural graphite production destined to North American, European and G7-allied markets. With potentially 100% of the future Phase-2 Matawinie Mine flake graphite production reserved, the Company is progressing its project development through engineering, procurement, and financing activities. Eric Desaulniers, Founder, President, and CEO of NMG, stated: "Thanks to our commercial partnerships we are tapping into industrial know-how, developed supply chain footprints, and strong diplomatic ties to broaden market access for the flake graphite from our Matawinie Mine. Our team is now actively engaged with lenders, strategic investors, and customers to line up financing efforts and term negotiations in view of FID." Renewed Commercial Strategy Through recently announced offtake agreements and term sheet arrangements, NMG has expanded its commercial approach to serve growth industries in the Western World, including the energy, defense, technology, and manufacturing sectors. This multimarket diversification provides NMG with the opportunity to maximize high-margin products in the Company’s portfolio and establish itself within North American, European and allied countries’ strategic supply chains. NMG and Panasonic Energy Co., Ltd. ("Panasonic Energy"), a wholly owned subsidiary of Panasonic Holdings Corporation ("Panasonic") (TYO: 6752) have revised their commercial agreement (the "2025 Panasonic Energy Binding Offtake Agreement") with the objective of advancing the production of 13,000 tonnes per annum ("tpa") of active anode material via NMG’s Phase-2 integrated value chain. Approximately 25,000 tpa of graphite concentrate is being reserved from the future Phase-2 Matawinie Mine production to execute this Panasonic Energy volume. The 2025 Panasonic Energy Binding Offtake Agreement contains conditions precedent and qualification requirements of the product and the commercial operations. NMG has signed a binding term sheet with the Government of Canada for a seven-year offtake of 30,000 tpa of graphite concentrate reserved for Canada and allied countries and entities for strategic applications and commercialization in domestic markets. Through this commitment, the Government of Canada is set to secure 15,000 tpa of graphite concentrate on a take-or-pay basis at a fixed North American market price and reserves 15,000 tpa for allied countries or entities, for NMG to formalize via offtake agreement(s) on similar terms. The term sheet offtake framework is conditional upon the Government of Canada receiving necessary approvals and completing its appropriation process, the parties executing definitive agreements including entering into at least one additional commitment from an allied countries or entities on substantially the same terms as the term sheet to purchase the reserved 15,000 tpa. A marketing term sheet in relation to the Government of Canada’s committed volume allows NMG to market their volume and includes a 50-50 profit split above the agreed upon fixed price net of any losses that the Government of Canada may have incurred and any marketing fees paid to NMG. NMG and Traxys North America LLC ("Traxys") have updated their commercial and marketing agreement ("2025 Traxys Binding Offtake and Marketing Agreement") to secure up to 20,000 tpa of graphite concentrate offtake from the Phase-2 Matawinie Mine for the refractory market in North America and Europe, which is subject to Traxys’ Board approval. With an initial seven-year term, the agreement includes sales pricing based on market indices with 10,000 tpa of firm take-or-pay volume. NMG is in active negotiations with an established anode manufacturer (the "Manufacturer") to secure up to 30,000 tpa of graphite concentrate from the Phase-2 Matawinie Mine over an initial six-year period. The take-or-pay portion of this volume, expected to represent approximately 15,000 tpa with sales pricing based on market indices with a floor price, is intended to serve as feedstock for active anode material production to potentially support General Motors Holdings LLC ("GM"), a wholly owned subsidiary of General Motors Co. (NYSE: GM), and other customers. There can be no assurance that NMG will be able to conclude the definitive agreements with the Government of Canada and/or allied countries and entities, and/or with the Manufacturer, that the Manufacturer and GM will be able to conclude a definitive agreement, or that NMG will be able to meet the conditions precedent of the 2025 Panasonic Energy Binding Offtake Agreement, the definitive agreements once executed or the conditions precedent of any or all of the offtake and marketing agreements mentioned above. Project Development and Path to FID NMG continues to advance its Phase-2 Matawinie Mine and Phase-2 Bécancour Battery Material Plant via samples production and process optimization at its Phase-1 and third-party facilities, engineering, and construction preparation. During the period, NMG completed the construction of key environmental infrastructure at the demonstration mining site and initiated new ore extraction campaigns to produce additional flake concentrate volumes at the Phase-1 Demonstration Plant. These volumes will enable supplementary product sampling and qualification for battery and strategic market segments. Procurement progresses for the Phase-2 Matawinie Mine through technical reviews and finalization of supply agreements for important equipment packages, alongside the negotiation of contracts with key suppliers, and the launch of civil, concrete, and steel tenders for the construction phase. In parallel, NMG is assessing the commercial and technical feasibility of an initial capacity in the Phase-2 Bécancour Battery Material Plant, with a view to efficiently fulfilling its committed volumes for Panasonic Energy. The project financing process has significantly advanced in recent months. The due diligence processes are well advanced, supported by specialized advisory firms, which are proceeding concurrently to assess the corporate, technical, market, and ESG components of NMG’s planned Phase-2 operations and to guide financial stakeholders’ risk assessment. The due diligence outcomes will feed into the structuring of legal documentation and a project debt package ahead of investment committee reviews. This workstream will be finalized upon having signed definitive agreements with offtakers. Negotiations on a long-form term sheet are ongoing ahead of the lenders’ respective investment committees to seek credit approval in the coming months. In light of its renewed commercial strategy, NMG intends to confirm the support of its strategic investors and targeted lenders toward the project financing, either for a combined FID encompassing the Phase-2 Matawinie Mine and the Phase-2 Bécancour Battery Material Plant, or for a sequenced FID starting with the Phase-2 Matawinie Mine followed by the Phase-2 Bécancour Battery Material Plant. Matawinie Mine Feasibility Study Results Considering the contemplated potential sequenced FID, NMG tasked BBA Inc. and various specialized consultants with the preparation of a segregated and updated feasibility study for the Phase-2 Matawinie Mine ("NI 43-101 Technical Report: 2025 Feasibility Study for the Matawinie Graphite Mine") in accordance with National Instrument 43-101 ("NI 43-101"). With a project globally unchanged, the NI 43-101 Technical Report: 2025 Feasibility Study for the Matawinie Graphite Mine refined some financial parameters to reflect the commercial agreements and latest CAPEX projections in line with ongoing procurement activities. Results continue to demonstrate technical and economic viability of the Phase-2 Matawinie Mine. Table 1: Operational and Economic Highlights of the Matawinie Mine Table 2: Current Pit-Constrained Mineral Resource Estimate for the West Zone Table 3: Mineral Reserve Estimate for the West Zone There is no certainty that the economic forecasts on which the NI 43-101 Technical Report: 2025 Feasibility Study for the Matawinie Graphite Mine is based will be realized. There are a number of risks and uncertainties identifiable to any new project and usually cover the mineralization, process, financial, environment and permitting aspects. Following an analysis of the major risks to the project, a P50 management risk reserve of $21M is recommended. This reserve is not included in the capital cost estimate but is within the range of the financial sensitivity analysis of the capital cost. The top risks are 1) construction productivity differing from baseline estimate; 2) longer-than-expected specialized equipment delivery times; and 3) contractor bids differing from the budget. A sensitivity analysis reveals that the viability of the Phase-2 Matawinie Mine will not be significantly vulnerable to variations in capital and operating costs within the margins of error associated with the NI 43-101 Technical Report: 2025 Feasibility Study for the Matawinie Graphite Mine estimates. However, the viability of the Phase-2 Matawinie Mine remains more vulnerable to the USD/CAD exchange rate and the larger uncertainty in future market prices. The 43-101 Technical Report: 2025 Feasibility Study for the Matawinie Graphite Mine will be filed on SEDAR+ at www.sedarplus.ca, EDGAR at www.sec.gov and on the Company's website at www.NMG.com within 45 days of this press release. Readers are encouraged to read the Study in its entirety, including all qualifications, assumptions and exclusions that relate to the details summarized in this press release. The Study is intended to be read as a whole, and sections should not be read or relied upon out of context. Market Perspectives FOB China prices for natural graphite and active anode materials have slightly lowered (Benchmark Mineral Intelligence, October 2025) during the period due to weak demand from refractory and battery sectors having sufficient inventory for current production. Preliminary duties imposed by the U.S. Department of Commerce on Chinese graphite imports have added meaningful extra costs for battery manufacturers, reinforcing the push for a North American supply chain decoupling. The EV market segment reached a record monthly high at the end of the period, with 2.1 million units sold worldwide in September 2025 (RhoMotion, October 2025). Global year-to-date growth accounts for +26%, with the U.S. sitting at +18%, China at +24%, and Europe rising to +32% while emerging economies such as Vietnam, Thailand and Brazil see very rapid growth (BloombergNEF, August 2025). The looming end of EV incentives and competitive model offerings continue to stimulate sales despite some policy changes. Analysts forecast that one in four new passenger cars sold globally in 2025 will be electric, while internal combustion engine sales are declining rapidly (BloombergNEF, August 2025). Global energy storage installations are poised to reach another record high in 2025 – rising 23% year over year – with China and the United States leading growth despite recent policy and trade challenges (BloombergNEF, October 2025). Strong expansion is also expected in Germany, the UK, Australia, Canada, Saudi Arabia, and across Sub-Saharan Africa, supported by favorable policies, utility procurement, and evolving power market dynamics. Overall, global annual storage deployments are projected to rise, setting a new all-time high. The global pipeline of battery production continues its gradual scale up with over 9,500 GWh planned by 2030 (Benchmark, October 2025). With current trade and geopolitical dynamics, jurisdictions are seeking to secure access to critical minerals and refining capacities (International Energy Agency, September 2025). G7 member countries adopted a Critical Minerals Action Plan aimed at strengthening and diversifying global supply chains for critical minerals, promoting transparent, rule-based markets, attracting new investment, and lessening non-competitive practices. Via its agreement with NMG, the Government of Canada intends to secure graphite for its domestic markets and stockpiling objectives, plus support allied nations and entities in building resilient and reliable supply chains. Canada and Germany signed a joint declaration to deepen cooperation in critical mineral supply chains with commitments to investments. The U.S. agreed to framework agreements with Australia, Japan, Thailand and Malaysia for securing supply in the mining and processing of critical minerals. Canada is deploying a $5 billion "Buy Canada" initiative to invest in resilient supply chains and position the country as a trusted global partner in advanced manufacturing and critical resources. The 2025 federal budget provides for $2 billion over five years to create the Critical Minerals Sovereign Fund, plus resources for the Major Projects Office to fast-track critical minerals extraction; envelopes targeting the development of innovative critical minerals processing technologies; and $25 billion by 2030 to expand Canada’s exports and trade development activities in sectors of strategic importance for Canada, including in critical minerals, energy, clean technology, infrastructure, and defense. China has announced, then temporarily paused new restrictions on the export of batteries, cathode and anode materials, rare earths and specialized equipment, raising instability and unreliability in the supply chain. Corporate The Company recruited Arnaud Quatannens to the position of Senior Director of Engineering, Battery Materials Plant. With over 20 years of international experience across the aluminum, aerospace, and battery industries, Mr. Quatannens has led complex engineering to large-scale operations. He joins NMG with a deep understanding of customer needs and market expectations in the battery sector to help scale industrial processes and bring the Phase-2 Bécancour Battery Material Plant to commercial operations. For the twelve-month rolling period ended September 30, 2025, NMG reported a total recordable injury frequency rate of 3.77 and severity rate of 1.88 at the Company’s facilities, and 0 at contractors’ worksites. There were no environmental incidents during this period. At the end of the period, the Company had a cash position of $61.7 million.

Forward-looking statements are based upon a number of estimates and assumptions that, while considered reasonable by the Company as of the time of such statements, are inherently subject to significant business, economic and competitive uncertainties and contingencies. These estimates and assumptions are not guarantees of future performance and may prove to be incorrect. Moreover, these forward-looking statements are based upon various underlying factors and assumptions, including the business relationship between the Company and its stakeholders, the ability to obtain sufficient financing for the development of the Matawinie Mine and the Bécancour Battery Material Plant, the Company’s ability to satisfy the due diligence processes of the stakeholders, and are not guarantees of future performance. Forward-looking statements are subject to known or unknown risks and uncertainties that may cause actual results to differ materially from those anticipated or implied in the forward-looking statements. Risk factors that could cause actual results or events to differ materially from current expectations include, among others, availability financing or financing on favorable terms for the Company, delays in the reaching FID, and general economic conditions, as well as earnings, capital expenditure, cash flow and capital structure risks and general business risks. A further description of risks and uncertainties can be found in NMG’s Annual Information Form dated March 31, 2025, including in the section thereof captioned "Risk Factors", which is available on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov. Unpredictable or unknown factors not discussed in this Cautionary Note could also have material adverse effects on forward-looking statements. Many of these uncertainties and contingencies can directly or indirectly affect, and could cause, actual results to differ materially from those expressed or implied in any forward-looking statements. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Forward-looking statements are provided for the purpose of providing information about management’s expectations and plans relating to the future. The Company disclaims any intention or obligation to update or revise any forward-looking statements or to explain any material difference between subsequent actual events and such forward-looking statements, except to the extent required by applicable law.
