I am delighted to see Daniel stepping up to lead the Board for this next chapter at NMG, best of success to Team Nouveau Monde!"

Eric Desaulniers, Founder, President, and CEO of NMG, declared: "While current geopolitics are challenging market conditions, we see continued growth in electric vehicles ("EVs") sales and deployment of energy storage systems for renewable power and data centers across the world. We maintain active engagement with our customers and targeted financial stakeholders to define and strengthen the commercial and financing framework of our integrated Phase-2 projects. And to guide our Company's next phase of development and growth, we welcome to the Board newly appointed experienced executives as Directors; bienvenue Paola and Judith! I take this opportunity to thank again our long-time investor Pallinghurst for their instrumental support over the years, as well as Jamie Scarlett for his contribution to the Company's sound governance."

Forward-looking statements are based upon a number of estimates and assumptions that, while considered reasonable by the Company as of the time of such statements, are inherently subject to significant business, economic and competitive uncertainties and contingencies. These estimates and assumptions are not guarantees of future performance and may prove to be incorrect. Moreover, these forward-looking statements are based upon various underlying factors and assumptions, including the business relationship between the Company and its stakeholders, the ability to obtain sufficient financing for the development of the Matawinie Mine and the Bécancour Battery Material Plant, the Company's ability to satisfy the due diligence processes of the stakeholders, and are not guarantees of future performance.

Forward-looking statements are subject to known or unknown risks and uncertainties that may cause actual results to differ materially from those anticipated or implied in the forward-looking statements. Risk factors that could cause actual results or events to differ materially from current expectations include, among others, availability financing or financing on favorable terms for the Company, delays in the reaching FID, and general economic conditions, as well as earnings, capital expenditure, cash flow and capital structure risks and general business risks.

Many of these uncertainties and contingencies can directly or indirectly affect, and could cause, actual results to differ materially from those expressed or implied in any forward-looking statements. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Forward-looking statements are provided for the purpose of providing information about management's expectations and plans relating to the future.
