Eric Desaulniers, Founder, President, and CEO of NMG, stated: “A defining milestone for the Matawinie Mine, this commitment from EDC and CIB reflects the depth of Canadian public-finance expertise behind large, strategic infrastructure and critical minerals developments — and it validates the bankability of our project. With detailed engineering well advanced, preparatory work executed, key permits secured, and agreements in place with the Atikamekw First Nation of Manawan and local community, Matawinie is shovel-ready and substantially de-risked. Backed by long-term offtake arrangements and a disciplined financing structure, we are advancing with confidence toward final investment decision ('FID') and construction.”

The Honorable Dominic LeBlanc, President of the King’s Privy Council for Canada, Minister of Internal Trade, and Minister responsible for Canada-U.S. Trade, Intergovernmental Affairs and One Canadian Economy, declared: “Nouveau Monde Graphite’s project is essential to accelerating the development of an integrated critical minerals value chain in Canada. By securing this long-term financing for Phase 2 of the Matawinie Mine, Nouveau Monde Graphite is helping strengthen a supply chain that is vital to our economic security, while supporting Canada and other G7 countries in sourcing critical minerals in a reliable and responsible way. With projects like this one, we are building a stronger and more prosperous Canada — creating good jobs, advancing the energy transition and unlocking Canada’s full economic potential.”

The Honorable Tim Hodgson, Minister of Energy and Natural Resources, said: “Graphite underpins battery supply chains, advanced manufacturing, and the technologies that shape the modern economy. We are the only G7 nation currently producing it, and by bringing the Matawinie Mine online, we can create new jobs and strengthen Canada’s role as a reliable supplier to our allies. The Government of Canada is helping move this project toward final investment decision and construction – just like we promised when we referred the project to the Major Projects Office. This is what execution looks like.”

The Honorable Joël Lightbound, Minister of Government Transformation, Public Works and Procurement and Quebec Lieutenant, stated: “Québec has everything it needs to be a leading player in the global battery supply chain: world-class resources, recognized industrial expertise, and regions ready to seize growth opportunities. By supporting projects like this one, our government is strengthening Canada’s position in the critical minerals sector, creating quality jobs for our workers, and ensuring that our industries have a reliable supply to build the economy of tomorrow.”

The Honorable Maninder Sidhu, Minister of International Trade, declared: “Canada’s critical minerals sector is key to building resilient supply chains and supporting the global transition to a low-carbon economy. By supporting projects like Nouveau Monde Graphite’s Matawinie Mine, which is set to become the largest graphite mine in the G7, we are strengthening Canada’s role as a reliable and stable partner in global critical mineral supply chains. This project will help grow Canadian exports, reinforce secure supply chains with our allies, and further position Canada as a global leader in responsibly produced critical minerals.”

The Honorable Gregor Robertson, the Minister of Housing, Infrastructure and Communities, and Minister responsible for Pacific Economic Development Canada said: “Projects like this are key to building the infrastructure and supply chains Canada needs for the future. The Matawinie Mine will strengthen our critical minerals value chain, create good jobs, and support sustainable economic growth while helping Canada and its allies secure the materials needed for clean energy and advanced manufacturing. Through this agreement in principle, we are helping move this important project forward and ensuring Canada remains a reliable partner in the global transition to a low-carbon economy.”

Claude Guay, Parliamentary Secretary to the Minister of Energy and Natural Resources, stated: “Québec offers the resource base, industrial capability, and project expertise needed to anchor globally competitive mining and critical minerals development. Today's announcement reflects the kind of strategic action our government is taking to create jobs and strengthen our economy and sovereignty, thanks to Quebec’s role in critical supply chains.”

Alison Nankivell, President and CEO, of EDC, added: “EDC is pleased to lead this financing round in support of the Nouveau Monde Graphite project, reflecting our commitment to building a strong, end-to-end critical minerals ecosystem in Canada. Projects like the Matawinie Mine play a strategic role, by strengthening domestic supply chains, creating high-quality jobs, and positioning Canada as a trusted global supplier of critical minerals. This is a great example of how EDC is deploying strategic risk capital to support nation-building projects that strengthen Canada’s economic resilience and advance the Government of Canada’s vision for a secure, sustainable, and globally competitive critical minerals sector.”

Ehren Cory, CEO of CIB, shared: “The CIB’s commitment of a debt facility to Nouveau Monde Graphite will advance the next phase of the Matawinie Mine toward final investment decision and construction. The CIB works to bridge financing gaps and accelerate timelines in large-scale critical minerals projects which are essential to Canada’s economic competitiveness.”

Key Financing Highlights
The Facilities account for a majority of the project’s capital structure and offer competitive terms supportive of long-term project economics. Facilities will be available upon completion of the definitive documentation, final legal, insurance and regulatory due diligence, and satisfaction of customary conditions precedents (collectively the “Conditions Precedents”). Société Générale is acting as debt advisor for this transaction.

• Total senior project-level debt facilities of US$335 million, including:
  • US$290 million senior secured term loan facility
  • US$45 million senior secured cost overrun debt facility
• Competitive interest rate and repayment structure to support commercial launch
• First-ranking security over the Matawinie Mine project and all material assets
• Aligned with international best practices for environmental, social and governance standards, including Equator Principles and IFC Performance Standards

The Facilities will be used to fund eligible project construction costs, working capital requirements prior to completion, and transaction costs associated with the financing. The cost overrun facility provides additional protection against construction cost overruns, subject to defined conditions.

The Phase-2 Matawinie Mine is supported by a portfolio of long-term offtake agreements, including agreements with the Government of Canada, Panasonic Energy Co., Ltd., a wholly owned subsidiary of Panasonic Holdings Corporation (TYO: 6752), and Traxys North America LLC, providing strong revenue visibility and underpinning the project financing structure.

Independent engineering, environmental and social, market, and other specialized advisors have been appointed to support the financing and oversee construction and ramp-up in accordance with the agreed development plan.

Path to FID
Following completion of Conditions Precedents, the Company expects to proceed to financial close and begin drawdowns under the term loan facility in accordance with the project schedule. Construction preparation, engineering, and procurement are advancing in parallel, with project execution aligned to the approved development plan. Major contracts awarded over the past few months, with provisions for full execution upon the Company having reached a positive FID, represent over 50% of the project’s CAPEX and are within estimates of NMG’s updated feasibility study for the Phase-2 Matawinie Mine in accordance with National Instrument 43-101.

The execution of the commitment letter represents a major milestone in the advancement of NMG’s fully integrated, responsible graphite value chain in Québec, Canada, and supports the development of a cornerstone asset for Western supply chains. The participation of EDC and the CIB reflects strong institutional confidence in the project’s fundamentals, its strategic importance to Canada’s critical minerals ecosystem, and NMG’s execution capabilities.

NMG is actively progressing its negotiations with targeted strategic investors for the equity component of the project financing with a view to completing the financing structure in a timely manner.
