Arne H Frandsen, Chair of NMG, declared: "We are writing a unique chapter in the global energy transition movement. Our sustainable-by-design value proposition continues to pull stakeholders, customers, and investors to NMG's story. Our offtake agreements with global leaders Panasonic Energy and GM, accompanied by equity participation and further committed investments, provide a strong testament of NMG's alignment with our customers' vision for sustainability. As governments adopt more stringent regulation on sourcing, carbon footprint, and transparent disclosure, NMG's attractiveness in the market continues to grow."

Eric Desaulniers, Founder, President and CEO of NMG, said: "At NMG, ESG principles are central to designing our projects in collaboration with communities and First Nations, developing our products, innovating on technologies, and reducing the potential impact of building and operating our facilities. It is also a rallying chant for our employees who are proud of doing things differently, with people and the planet in mind. To that end, I salute Team Nouveau Monde and our partners for their engagement in advancing our initiatives and elevating our performance."

Driving Sustainability and Accountability

NMG's commitment to environmental stewardship remains steadfast, with significant progress achieved across key metrics. The Company proudly reports having maintained a track record of 0 major environmental incidents, 100% of water quality standards met at its Matawinie Mine, and a carbon-neutral footprint. In that regard, NMG signed definitive agreements with Caterpillar Inc. this year to frame the deployment of technology, our testing collaboration, as well as the procurement of a zero-exhaust emission fleet and infrastructure for the Matawinie Mine.

Recognizing the importance of biodiversity conservation, NMG has embraced a proactive approach to safeguarding nature through sustainable engineering of its Phase-2 facilities, protection measures for threatened species and sensitive habitats, and proactive reclamation efforts. The Company has also adopted a Water Stewardship Policy this year that sets out guidelines on governance, water management, and collaboration with stakeholders.

NMG continues to prioritize open and proactive engagement with communities and First Nations as it advances its projects, fostering respect, collaboration, and opportunities. Initiatives include employee training on Indigenous realities and unconscious bias, an adapted job application process for Indigenous workers including content in Atikamekw and Innu-Aimun languages, as well as outreach efforts for community and business engagement.

As part of its Diversity, Equity, and Inclusion action plan, NMG advanced various initiatives including the participation to an international recruitment mission, updating its corporate materials to ensure representation of its diverse workforce, and systematic integration of content related to diversity topics in its internal communications to promote the benefits of an open workplace. The Company also promotes innovative workforce practices such as paid, alternating work-study programs in collaboration with school boards and other industrial partners to support the development of a skilled local workforce ahead of commercial operations.

NMG strengthened its responsible procurement practices to emphasize high standards on social and environmental performance, seek eco-friendly sourcing and promote opportunities for local and Indigenous businesses. In 2023, 79% of NMG's procurement was based in Québec, with $4.9 million in contracts directly within its communities.

The health, safety, and well-being of NMG's workforce remains paramount. NMG initiated a culture-shaping initiative in 2023 that is set to extend and expand as the Company grows. For the twelve-month period ended March 31, 2024, NMG had an Occupational Safety and Health Administration ("OSHA") recordable incident rate of 4.30 and a severity rate of 0.

Advancing a Turnkey Ore-to-Battery-Materials Production

The project execution strategy is now outlined for the construction of the Matawinie Mine and Bécancour Battery Material Plant once a final investment decision ("FID") is reached. The Company is advancing an integrated project team ("IPT") model where NMG's owner team will be assisted by strategic partners in engineering, procurement, construction management and project controls. The IPT strategy offers several advantages, including greater control over the project's direction as well as reduced project management and engineering costs.

Ongoing engineering activities, preparation for construction and procurement strategy are being integrated into this model, with active progress for both projects. Building on intel from its Phase-1 operations and integrating the specifications from its Anchor Customers, NMG is actively updating the production parameters of its Phase-2 Bécancour Battery Material Plant. For example, furnace construction materials aligned with NMG's Phase-2 commercial furnaces were installed and are being tested so performance and data from production activities can inform parallel engineering.

At NMG's 200,000-m² land in the Bécancour industrial park in Québec, tree clearing was carried out in advance of preparatory work. Adjacent to the Company's Phase-1 purification plant, the greenfield site provides a central location for building the Phase-2 Bécancour Battery Material Plant, in the heart of the battery industrial hub being developed, including GM-POSCO.

Securing a Solid Foundation for a Commercial Development

After having entered into offtake agreements with Anchor Customers for its active anode material, covering approximately 85% of the Company's planned Phase-2 fully integrated production, NMG is reinforcing commercial discussions with other tier-1 battery and EV manufacturers for the remainder volumes. NMG's attractive fully integrated, local, and scalable production model, aligned with sourcing requirements and trade restrictions from key jurisdictions provide strong tailwinds for the Company's commercial engagement.

In parallel, NMG continues to advance financing efforts for its Phase-2 Matawinie Mine and Bécancour Battery Material Plant in view of FID. With Panasonic Energy and GM multiyear supply contracts plus long-term engagement as shareholders, NMG can demonstrate long-term bankability underpinnings. The Company is engaged with export credit agencies, governments, strategic investors, and potential customers to refine a robust capital structure that leverages international debt, government funding and equity. The Company's project financing approach also strives to leverage fiscal incentives such as Canada's Investment Tax Credit for Clean Technology Manufacturing, a refundable tax credit of up to 30% of eligible capital expenditures.

Following regulatory approval and positive support by NMG shareholders, in accordance with Regulation 61-101 Protection of Minority Security Holders in Special Transactions ("Regulation 61-101"), the Company closed private placements for an aggregate US$37.5-million private placements from Mitsui & Co., Ltd. ("Mitsui") and Pallinghurst Bond Limited ("Pallinghurst") for the surrender and cancellation of each of Mitsui's and Pallinghurst's convertible notes dated November 8, 2022, as amended and restated.

NMG's period-end cash position is $88 million.

Aligning with Market and Policy Trends

In Q1-2024, global EV sales reached 3.1 million units and grew 21% quarter-on-quarter (Rho Motion, April 2024). The International Energy Agency estimates 17 million global sales in 2024, with more than 1 in 5 cars sold worldwide set to be electric (IEA, April 2024). The adoption of EVs in North America is currently being stimulated by the introduction of multiple new models by leading market participants, a price war among EV manufacturers and structuring partnerships to accelerate the deployment of charging networks.

A trend towards reshoring supply chains and manufacturing capacity is becoming apparent through trade tensions, governmental incentives, and industry announcements. Canada is among the emerging leaders of this new economy (BloombergNEF, February 2024), and has now attracted more than $31 billion in investments from EV and battery manufacturers since 2021 (Government of Canada, April 2024). Honda is of the number with a $15-billion plan to establish a comprehensive supply chain in Canada through battery materials processing, battery manufacturing, and EV assembly plants set to be fully operational in 2028.

In the U.S., the Biden Administration is forging ahead with incentives and sourcing requirements associated with the Inflation Reduction Act ("IRA"). The final rule will oblige EV manufacturers to demonstrate a meaningful procurement plan to secure compliant supply chains for certain battery materials, including graphite, in the transition period to 2027.
