Nouveau Monde Graphite Inc. (“NMG” or the “Company”) (NYSE: NMG, TSX: NOU) is reporting continued progress in advancing its Phase-2 Matawinie Mine and Phase-2 Bécancour Battery Material Plant toward reaching a final investment decision (“FID”) thanks to technical project development, active financing activities, and commercial engagement with customers. Current trade and geopolitical dynamics create a changing environment for NMG’s development, with both opportunities and challenges; hence, the Company is exploring various financing and commercial scenarios to lessen risk exposure and facilitate its market entry.

Eric Desaulniers, Founder, President, and CEO of NMG, declared: “Resource nationalism, tariffs, policy headwinds, and shifting global alliances are creating uncertainty in global supply chains and investment planning. Nevertheless, we remain centered on our mission to develop a responsible and resilient North American graphite value chain for the battery sector to help meet the expansion of the electric vehicle (“EV”) and energy storage markets. We are refining our execution plan to capitalize on positive political and commercial interests, while reducing vulnerabilities associated with uncertainties.”

Advancement Toward FID: Project & Financing Update

Since issuing the NI 43-101 Updated Technical Feasibility Study Report for the Matawinie Mine and Bécancour Battery Material Plant Integrated Graphite Projects (the “Updated Feasibility Study”), NMG has pursued the development of the Phase-2 Matawinie Mine in preparation for FID. Detailed engineering, negotiation of contracts with key suppliers, preparation of call for tenders for construction, value engineering, electrification planning, and schedule optimization are ongoing to advance the project. The Company has also initiated work for key environmental infrastructure at the demonstration mining site in view of additional flake production at the Phase-1 Demonstration Plant.

In parallel, NMG is actively focusing on advancing engineering of the Phase-2 Bécancour Battery Material Plant to optimize processing technologies and refine environmental, operational, and financial parameters, in view of reaching FID. Engineering is being supported by specialized Asian firms with expertise in the graphite and anode material industry. Large-scale testing and sample production are being planned at partnering facilities to inform engineering and commercialization efforts.

The Company is working with its Anchor Customers and other potential tier-1 customers toward bankable offtake agreements paired with strategic investments to bring NMG’s Phase-2 Matawinie Mine and Phase-2 Bécancour Battery Material Plant to FID, subject to their respective technical, commercial and financing parameters. The Company is exploring various financing and commercial scenarios to lessen risk exposure in light of current geopolitical conditions, including the possibility of sequencing financing stages.

Financing activities continue to progress via engagement with its customers, potential lenders, and targeted institutional equity investors with a view to advancing key requirements. To date, the Company has received letters of interest toward the debt financing structure for over US$1 billion toward the Company’s Phase-2 Matawinie Mine and Bécancour Battery Material Plant. Targeted capital providers include various governmental bodies, public institutions, and export credit agencies, namely Export Development Canada and Canada Infrastructure Bank. The financing structure at FID is set to also include an equity participation from key investors, including the Company’s Anchor Customers.

Market Perspectives

The global EV momentum remains strong despite some policy headwinds in North America. Over nine million EVs were sold worldwide in the first half of 2025, a 28% year-to-date increase that saw significant growth in China (+32%) and Europe (+26%), while the North American EV market slowed to just 3% growth (Rho Motion, July 2025). According to the International Energy Agency, global EV sales are on track to exceed 20 million in 2025. GM, NMG’s Anchor Customer, emerged as the #2 EV manufacturer in the U.S., with EV sales up 104% in H1 2025. In Canada, GM secured the #1 place in Canadian EV sales, posting a 38% year-over-year increase (GM, July 2025).

Energy storage is experiencing record growth with global grid-scale deployments increasing by over 50% in H1 2025 (Rho Motion, July 2025), fueled by new renewable energy capacity, AI-driven electricity demand and grid resilience infrastructure. Rho Motion tracked 14 gigascale projects (>1 GWh) entering operation in 2025 so far, and over 300 such projects scheduled for completion before 2027. The International Energy Agency forecasts a 180% increase in global data center electricity demand by 2030, bolstering the need for large-scale storage. GM announced a partnership with Redwood Materials to supply batteries for data centers, marking AI infrastructure as a second major growth market for lithium-ion batteries beyond EVs (GM, July 2025).

The global pipeline of battery production remains robust at 9,275 GWh (Benchmark, July 2025). New capacity is coming online, namely Panasonic Energy’s, NMG’s Anchor Customer, De Soto plant inaugurated in July 2025. The Kansas factory is set to boost Panasonic Energy’s U.S.-based production capacity to approximately 73 GWh and help meet the demand from automotive customers expanding their EV production (Panasonic Energy, July 2025). Panasonic Energy is targeting a 50% local supply chain integration and full production by year-end, while diversifying its EV client base across established OEMs and start-ups (Bloomberg, July 2025).

Resetting American policies on clean technology and strategic sectors, the newly adopted American One Big Beautiful Bill Act tightens domestic content rules for battery manufacturing and imposes new limits to exclude China and other foreign entities of concern from critical mineral supply chains. The legislation also eliminates and/or phases out incentives in several sectors but preserves battery storage tax credits. It also allocates US$2.0 billion for the National Defense Stockpile to acquire strategic and critical minerals, and US$5.0 billion to the Department of Defense’s Industrial Base Fund for investments in critical mineral supply chains (U.S. Congress; SFA Oxford, July 2025).

Moreover, the U.S. Department of Commerce announced preliminary affirmative determinations as part of its antidumping and countervailing duties investigation of active anode material from China (International Trade Administration, July 2025). Combined tariffs on Chinese graphite-based active anode material bring effective duties to 160%, thus improving the competitiveness of North American producers (Benchmark Mineral Intelligence, July 2025). Final duties determination is expected in December 2025.

Members of the North Atlantic Treaty Organization (“NATO”), a political and military alliance of countries from Europe and North America, adopted a new Defense Investment Pledge of 5% of GDP by 2035, including 1.5% for defense-adjacent infrastructure such as critical minerals development. NATO lists graphite among 12 essential minerals for defense technology (NATO, July 2025). Investments in Canadian critical minerals not only strengthen NATO readiness but also reduce reliance on Chinese-controlled supply chains.

Management notes that current trade and geopolitical dynamics—marked by rising tariffs, shifting alliances, and growing resource nationalism—are injecting significant uncertainty into global supply chains and investment planning. EV adoption remains strong globally but is encountering policy headwinds in North America, while energy storage emerges as the next major growth driver, fueled by rising AI and data center power demand. Geopolitical fragmentation and reconfiguration of global trade flows are reshaping alliances and leading to volatility in investment and operational planning, with firms delaying or altering strategies amid uncertainty. Together, these shifts may reshape market demand, investment flows and supply chain strategies across the Western World (World Economic Forum, June 2025).
