("Panasonic Energy") and other leading battery and electric vehicles ("EV") manufacturers are progressing well to advance the development of green and reliable supply chains. Clean energy is gaining momentum beyond industry thanks to North American and European governments' policies and stimuli. Their active involvement signals a shift in economic constructs through ESG-focused regulation and financial incentives, strengthening the foundations on which we are developing our integrated operation."

NMG's 2022 ESG Report can be consulted online.

The Company's 2022 ESG Report presents the management approach, key programs, advancements, case studies, and metrics covering NMG's activities at its Phase-1 operations, in planning its Phase-2 Matawinie Mine and Bécancour Battery Material Plant, as well as for corporate development and contemplated Phase-3 Uatnan Mining Project. Among the major advancements during the exercise, NMG enhanced its climate action and resilience, biodiversity management, Indigenous relations, governance, and stakeholder engagement.

The report leverages the Global Reporting Initiative ("GRI"), the Value Reporting Foundation (SASB Standards), the Task force on Climate-related Financial Disclosures ("TCFD"), and the United Nations Global Compact disclosure frameworks in line with best practices. Standardized reporting enables shareholders, asset managers, and stakeholders to consult, compare, and analyze the Company's management of environmental, social and governance ("ESG") material issues.

Integrated Operations & Phased Development

The Company's Phase-1 operations continue to produce graphite materials to support product qualification efforts with leading battery and EV manufacturers. The new shaping equipment successfully installed in 2022 is now fully commissioned. Tests have generated positive results with samples produced that met various potential client specifications. Production is set to ramp up during the year. The commissioning of the coating module is progressing in parallel.

NMG is actively advancing plans for the Phase-2 Matawinie Mine and Bécancour Battery Material Plant in line with commercial discussions. The Company developed the project's execution and contracting strategy in preparation for construction once a final investment decision ("FID") is reached.

On the foundation of their 2021 collaboration agreement and of technical work achieved together over the past two years, the Company and Caterpillar Inc. ("Caterpillar") have signed definitive agreements to supply NMG's Matawinie Mine with an integrated solution that covers a zero-exhaust emission fleet, supporting infrastructure, and service. Caterpillar is set to be NMG's supplier of heavy mining equipment, supporting the progressive transition from traditional models to Cat® zero-exhaust emission machines as they become available. Depending on the commercialization of Cat® zero-exhaust emission machines, Caterpillar will reserve production slots, which should enable the Company to benefit from timely deliveries and technology enhancements throughout the duration of the contract. Furthermore, Caterpillar's Job Site Solutions will help reduce NMG's initial capital intensity for the Matawinie Mine by providing access to equipment through an hourly fee based on usage and includes asset management support to help improve uptime, predictability, and efficiency.

Commercial Engagement & Market Outlook

In addition to their collaboration on mining fleet electrification, the Company and Caterpillar have signed a memorandum of understanding ("MoU") to advance commercial discussions targeting NMG's active anode material. Through this MoU, a full circular value chain could be established whereas NMG would supply carbon-neutral graphite materials to Caterpillar for the development of its secure, resilient, and sustainable battery supply chain that would serve to electrify heavy vehicles, including NMG's Matawinie fleet.

Technical work and commercial discussions are advancing between the Company and Panasonic Energy to finalize product qualification and establish a contemplated multi-year definitive offtake agreement for a significant portion of NMG's active anode material out of the Company's fully integrated "ore-to-anode-material" Phase-2 facilities.

In line with its active marketing and commercialization program, NMG is also engaged with top-tier battery and EV manufacturers across continents through the supply of samples in a variety of specifications meeting individual requirements, site visits, and sales discussions with a view to establish offtake agreements.

NMG's commercial engagement matches the growth in EVs, renewable energy solutions and electronics markets; EV sales are expected to reach 22.5 million units by 2025 (Rho Motion, Q1-2023). Global battery production is rapidly expanding; 2023 is set to see manufacturing capacity reach 1 TWh for the first time. By the end of 2030, the global lithium-ion battery production capacity is projected to soar to 8,493 GWh, multiplying demand for advanced materials up to fivefold, with graphite outpacing all other battery metals (Benchmark Mineral Intelligence, April 2023) at 10,809,000 tonnes per annum.

With manufacturers facing a challenge to secure the raw materials needed, NMG is heading to Europe's Battery Show in Stuttgart, Germany on May 23-25, 2023. The trade show is dedicated to advanced battery technology for electric and hybrid vehicles, utility and renewable energy support, portable electronics, medical technology as well as telecommunications. The Company's Sales and R&D team will be onsite, at booth 8C34, to meet key industry players and examine some of the latest technologies that could complement NMG's operations. Patrice Boulanger, Vice President, Sales, Marketing & Business Development, will participate to the "AFFORDABLE EVs with Silicon-Enabled Longer Range, Smaller, Cheaper, Faster Charging Batteries" panel on May 25, 2023.

On June 6-9, 2023, the Company will promote its ESG credentials and climate-focused business model at TD Cowen's Sustainability Week rallying sustainability-focused investors and stakeholders. President and CEO Eric Desaulniers will take part in a fireside chat on June 6, 2023, at 9:45 a.m. ET; investors can virtually join the session via webcast at https://wsw.com/webcast/cowen135/nmg/1846602.

NMG will also join the marketplace at the Battery Gigafactories USA 2023 conference in Washington, DC, on June 8-9, 2023, to engage with energy industry leaders, automotive OEMs, battery gigafactory operators, government officials, financial institutions, and the global lithium-ion battery supply chain. Eric Desaulniers will take the stage on June 9, 2023, for the "Graphite & Anodes" session that will explore ex-China flake graphite in development, forecasted challenges and opportunities.
