SCHEDULE 13D




Comment for Type of Reporting Person:
This Amendment No. 2 to the Schedule 13D (this "Amendment No. 2") amends and supplements the Schedule 13D originally filed by the Reporting Person on November 18, 2022 and amended on May 6, 2024 (as amended, the "Schedule 13D"), and relates to the Reporting Person's beneficial ownership of Common Shares, no par value, and Common Share Warrants of Nouveau Monde Graphite Inc., a corporation existing under the federal laws of Canada ("NMG" or the "Issuer"). Only those items that are hereby reported are amended; all other items reported in the Schedule 13D remain unchanged. Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable. Capitalized terms not defined in this Amendment No. 2 have the meanings ascribed to them in the Schedule 13D. This Amendment No. 2 is being filed to reflect the dilution of the Reporting Person's beneficial ownership in the Issuer as a result of the Private Placement and Subscription Receipt Exchange described in Item 5 below, as well as the earlier dilution of the Reporting Person's beneficial ownership in the Issuer as a result of the Issuer Offering on December 20, 2024 described in Item 5 below. This filing constitutes a late filing with respect to the Issuer Offering due to administrative error.
