Entry into a Material Definitive Agreement.

On May 16, 2025, Vision Marine Technologies, Inc. (the “Company”) entered into a Settlement Agreement and Release (the “Settlement Agreement”) with three of its shareholders (the “Holders”) to resolve claims made by the Holders in Ionic Ventures, LLC, et al. v. Vision Marine Technologies, Inc., Index No. 651289/2025 (Sup. Ct. N.Y. Co.) (the “Matter”).

Under the Settlement Agreement, the Company agreed to issue an aggregate of 250,000 common shares of the Company (the “Settlement Shares”) to the Holders, subject to court approval under Section 3(a)(10) of the Securities Act of 1933, as amended.

Upon issuance, the Settlement Shares may be resold without restriction, subject to a partial lock-up provision. Under the lock-up, each Holder may not sell more than its pro rata portion of 20% of the daily trading volume of the Company’s common shares on any trading day. This restriction is subject to early termination under certain conditions, including a capital raise by the Company or a sustained increase in trading volume.

The Settlement Agreement also includes mutual releases of all claims related to the Matter. The effectiveness of the releases is contingent upon court approval of the share issuance under Section 3(a)(10) by September 15, 2025. The Company expects to seek expedited court approval of the Settlement Agreement and the issuance of the Settlement Shares.

The foregoing is a summary of the Settlement Agreement which is qualified in its entirety by reference to the full text of the Settlement Agreement that is attached hereto as Exhibit 10.1 and hereby incorporated by reference herein.
