MONTRÉAL--(BUSINESS WIRE)--May 13, 2026-- On the heels of key project financing milestones, Nouveau Monde Graphite Inc. (“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.

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260513049409/en/

NMG’s 2025 ESG Report is available for consultation at https://nmg.com/wp-content/uploads/2026/05/NMG-2025-ESG-Report.pdf.

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. Copies of the notice of meeting, the management information circular, the proxy form, the voting instruction form, financial statements and the Fighting Against Forced Labor and Child Labor Report are available on NMG’s website and in Canada on SEDAR+ at www.sedarplus.ca and in the U.S. on the SEC’s website at www.sec.gov.

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).

Natural graphite remains designated as a critical mineral across major jurisdictions, reinforcing its strategic importance as governments respond to evolving energy security and supply chain risks.
