Following the issuance of 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"), Nouveau Monde Graphite Inc. ("NMG" or the "Company") (NYSE: NMG, TSX: NOU) is advancing its Phase-2 commercial plans with progressing work on the project financing, engineering, procurement and construction preparation. The Company also files its 2024 ESG Report that demonstrates continued stewardship of environmental, social and governance ("ESG") issues aligned with global decarbonization efforts and international standards as required by lenders, investors, and customers.

Arne H Frandsen, Chair of NMG, said: "NMG is cleverly navigating the shifting global market, while steadfastly maintaining its ESG commitments. Our business model, rooted in the clean energy transition, strives to capitalize on Western economies' growing appetite for critical minerals, local and ESG-compliant supply chains, as well as reshoring manufacturing capacity. Our commercial agreements with Panasonic Energy and General Motors along with strong interest from strategic lenders and institutional investors strengthen our plans to develop a responsible and carbon-neutral source of active anode material, positioning NMG as a sustainable and innovative supplier for long-term growth."

Eric Desaulniers, Founder, President, and CEO of NMG, declared: "Consumer demand for electric vehicles ("EV") is undisputable and catalyzes the battery value chain, a strong driver for active anode material. Facing steep tariffs and tightening supplies, manufacturers are seeking alternatives to Chinese active anode material. NMG's ore-to-battery-material Phase-2 Matawinie Mine and Bécancour Battery Material Plant are timely set to enter market, offering simplified trade corridors, ESG compliance, reliability, and a scalable source."

Technical Development & Execution Strategy

On the heels of the Updated Feasibility Study, NMG is actively advancing the project development in preparation for the final investment decision ("FID") through engineering, negotiation of contracts with key suppliers, preparation of call for tenders for construction, value engineering and schedule optimization.

Engineering for both the Matawinie Mine and Bécancour Battery Material Plant is progressing thanks to engagement with equipment vendors, specialized firms, and technological advancement. NMG is namely working on the purification process to refine environmental performance, operational, and financial parameters leveraging data from test results and sampling production at partnering facilities. The Company has enlisted specialized Asian firms with expertise in the graphite and anode material industry to support technical development.

In parallel, NMG has presented the Updated Feasibility Study results to its Anchor Customers, potential lenders, and targeted institutional equity investors as part of the financing stage. To date, the Company has received cumulative expressions of approximately $1.6 billion and identified a potential for securing approximately $450 million through the new refundable Canadian Investment Tax Credit for Clean Technology Manufacturing.

Numerous advanced stage due diligence exercises, supported by specialized firms, are proceeding concurrently to examine the corporate, technical, market, and ESG components of NMG's planned Phase-2 operations and guide financial stakeholders' risk assessment.

ESG & Corporate Matters

As the Company continues to advance its Phase-2 project financing and future commercial operations, NMG continues to strengthen its intendance of material ESG issues aligning with internationally recognized practices endorsed by potential lenders, institutional investors, and customers. In addition to its proactive climate action, significant milestones this year include the addition of scenario analysis to the Company's climate risk management, the signature of an impact and benefit agreement with the Atikamekw First Nation of Manawan, the expansion biodiversity efforts, a notable improvement in the Company's CDP climate score, and strengthened community and Indigenous engagement. This performance, combined with a demonstrated governance framework and a focus on responsible business practices, position NMG as a leader in sustainable graphite production (Benchmark Mineral Intelligence, March 2025). NMG's 2024 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, 2025, NMG reported a total recordable injury frequency rate ("TRIFR") of 1.77 and severity rate of 2.65 at the Company's facilities. In 2024, NMG maintained its track record with no major environmental incidents.

To mark the Company's uplisting to the Toronto Stock Exchange, NMG's leadership took advantage of an investor and financing tour to open the market on April 24, 2025.

Considering the change of technology and upcoming lease expiry for the industrial space in Olin's facility in Bécancour, NMG has initiated the decommissioning of its Phase-1 Purification Plant. The remaining of the Phase-1 operations located in Saint-Michel-des-Saints are operating as usual for the foreseeable future to continue producing flake concentrate from the Matawinie deposit, as well as preparing and testing large-scale qualifying active anode material samples for actual and potential tier-1 customers.

At the end of the period, the Company had a cash position of $89 million.

Market Perspectives

The graphite and battery sectors are undergoing rapid transformation, driven by the adoption of EVs and energy storage systems ("ESS"). During the period, global EV sales went up 29% compared to the same period last year, with Europe bouncing back at +22% and North America at +16% (Benchmark Mineral Intelligence, April 2025). The global ESS market grew 65% year-over-year (Rho Motion, April 2025).

This growth reverberates upstream in battery manufacturing. The lithium-ion battery production pipeline is now estimated to reach 9,300 GWh by 2030, with Europe driving the highest demand after China (Benchmark Mineral Intelligence, April 2025). NMG's Anchor Customer GM announced that its EV battery production has now surpassed that of Tesla in the U.S. (Bloomberg, April 2025).

While market growth presents significant opportunities, supply chain vulnerabilities and geopolitical tensions pose challenges, particularly for North America. Efforts are underway to diversify and localize production considering the region remains heavily reliant on imports; the U.S. was 100% dependent on foreign graphite to meet its demand in 2024 (Benchmark Mineral Intelligence, April 2025).

North America faces challenges in establishing a domestic graphite supply chain; the U.S. International Trade Commission is investigating trade activities following a petition from the American Active Anode Material Producers seeking antidumping and countervailing duties on Chinese imports (Bloomberg, January 2025).

Moreover, tension and reciprocal measures escalated between the U.S. and China during the period. U.S. manufacturers face steep tariffs on Chinese graphite and anode material. Analysts predict a positive shift toward ex-China natural graphite anode materials as a result (Fastmarkets, April 2025).

Amid the global graphite market unprecedented turbulence, U.S. executive orders and policies, including the Export-Import Bank of the United States' ("EXIM") Supply Chain Resiliency Initiative that enables the financing of international projects with offtake critical minerals agreements with U.S. companies, emphasize the importance and urgency of securing the raw materials needed for energy applications and national security.

Annual General and Special Meeting of Shareholders

NMG will hold its annual general and special meeting of shareholders (the "Meeting") on Tuesday, June 17, 2025, at 10 a.m. (Eastern Time) via live webcast at https://virtual-meetings.tsxtrust.com/en/1797.
