The Honourable Tim Hodgson, Canada's Minister of Energy and Natural Resources, and Eric Desaulniers, NMG's Founder, President, and CEO, executed binding supply and marketing term sheets establishing a multiyear framework for an aggregate of 30,000 tpa of graphite concentrate from the Phase-2 Matawinie Mine, including a 15,000 tpa take-or-pay commitment by the Government of Canada, with the balance to be secured from allied countries and entities.

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 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.
