Key Terms

4 terms

unsecured convertible note financial

"under the unsecured convertible note, as amended and restated"

An unsecured convertible note is a loan a company takes from investors that has no collateral backing it and can later be exchanged for the company’s shares instead of being repaid in cash. Think of it as an IOU that can be swapped for ownership: it matters because lack of collateral raises the risk of loss if the company fails, while the conversion feature can lead to upside if the company’s value rises and to share dilution for existing owners.

related party regulatory

"constitutes a “transaction with a related party”"

A related party is a person or organization with close ties to a company — for example major shareholders, board members, executives, their family, or businesses they control — that can influence decisions or enter into transactions with the company. Investors watch related‑party dealings because they can create conflicts of interest or non‑market terms that affect fairness, the company’s finances and transparency; think of it like buying or selling something to a family member rather than on the open market.

official valuation obligation regulatory

"exemptions from the official valuation obligation"

hold period regulatory

"subject to a hold period of four (4) months and one day"

A hold period is a specific span of time during which an investor is required or expected to keep a security or asset and cannot freely sell it or realize its value. It matters because it limits liquidity and can affect tax treatment, risk exposure and timing of gains or losses—like a cooling-off or fixed-term commitment that prevents you from quickly cashing out even if market conditions change.

PRESS RELEASE

For immediate release

NMG Pays Accrued Interests

MONTRÉAL, CANADA, October 1, 2026 – Nouveau Monde Graphite Inc. (“NMG” or the “Company”) (NYSE: NMG, TSX: NOU, FSE: NM9A) announces the payment of accrued interests as part of a previously announced private placement.

Settlement of Accrued Interests

Upon the approval of the Toronto Stock Exchange and the New York Stock Exchange (the “Exchanges”), the accrued interests owed to Investissement Québec (“Holder”) for the third quarter of 2026 under the unsecured convertible note, as amended and restated, (the “Note”) issued in connection with the private placement announced by press release dated November 8, 2022, will be deemed paid.

283,265 common shares at a price of US$1.21 (each, a “Common Share”) representing an aggregate amount of US$342,751 will be issued and share certificates will be delivered to the Holder at the maturity, conversion or redemption of the Note in payment of the accrued interests due on September 30, 2026, for the third quarter of the year. The issuance of Common Shares is subject to the approval of the Exchanges and, when issued, will be subject to a hold period of four (4) months and one day.

The payment of interest in the form of Common Shares of the Corporation takes place in favor of Investissement Québec, a holder of more than 10% of the securities of the Company, which constitutes a “transaction with a related party” within the meaning of Regulation 61-101 on measures to protect minority holders during specific transactions (“Regulation 61-101”). However, the directors of the Company, who voted, have determined that the exemptions from the official valuation obligation and the approval of minority holders, provided for in sections 5.5 a) and 5.7 1) a) of Regulation 61-101 respectively, may be invoked as neither the fair market value of the shares issued to this insider nor the fair market value of the consideration paid does not exceed 25% of the market capitalization of the Company. No director of the Company has expressed a contrary opinion or disagreement in connection with the foregoing.
