Mitsui & Co. Reports Diluted 7.6% Stake in Nouveau Monde Graphite Following Issuer Offerings

Mitsui & Co., Ltd. filed an amendment to its Schedule 13D for Nouveau Monde Graphite Inc. (NMG) on May 19, 2026, primarily to report a dilution of its ownership stake. As of May 15, 2026, Mitsui beneficially owns 26,052,695 shares (including 13,552,695 common shares and 12,500,000 warrants), representing approximately 7.6% of the company on a partially diluted basis. This reflects a significant decrease from a previous 15.8% stake reported in December 2024. The dilution resulted from several issuer-driven events, including a private placement with Canada Growth Fund Inc., Investissement Quebec, and ENI S.p.A., as well as a prior common share offering on December 20, 2024. Mitsui noted that due to an inadvertent administrative error, it had previously failed to file a timely amendment to report the 'One-Percent Decrease' triggered by the December 2024 offering. The filing confirms that Mitsui has not engaged in any transactions involving NMG common shares within the past 60 days.
