Vision Marine Technologies Advances E-Motion™ Power Distribution Unit Manufacturability and Engages Contract Manufacturer to Support Production Planning

Technology / E-Motion™ Platform Development

Vision Marine has improved the manufacturability of its E-Motion™ Power Distribution Unit and engaged a contract manufacturer to support production planning for a key high-voltage component. The work strengthens E-Motion™ manufacturing readiness and supports the platform's roadmap toward future compatibility with fast-charging infrastructure for higher-use applications, including commercial operators, boat clubs, rental fleets and marina environments.

BOISBRIAND, QC, June 4, 2026 /PRNewswire/ -- Vision Marine Technologies Inc. (NASDAQ: VMAR) (TSXV: VMAR) ("Vision Marine" or the "Company"), a marine technology company specializing in high-voltage electric marine propulsion and recreational boating solutions, today announced that it has improved the manufacturability of the Power Distribution Unit ("PDU") used in its E-Motion™ high-voltage electric marine propulsion system and has engaged a contract manufacturer to support production planning for the component.

The PDU is a core component of the E-Motion™ high-voltage architecture, managing the distribution of electrical power between key system components. Vision Marine's recent manufacturability work is intended to further streamline production of the PDU and prepare the component for future production requirements as customer and OEM programs develop. The Company has also engaged a contract manufacturer to support production planning and manufacturing readiness for the PDU, while Vision Marine maintains control over system architecture and marine-specific engineering requirements.

The enhanced PDU architecture also supports Vision Marine's broader charging roadmap. E-Motion™ currently includes an integrated onboard charger that allows boaters to charge from commonly available dockside shore-power outlets. This approach remains important for everyday use within existing marina environments. At the same time, the Company is evaluating how the E-Motion™ architecture may support future compatibility with fast-charging infrastructure where available, which may be relevant for higher-use applications such as commercial operators, boat clubs, rental fleets and marina-based operations.

"From the beginning, E-Motion™ was designed to make electric boating practical with the marina infrastructure already available today," said Maxime Poudrier, Chief Operating Officer of Vision Marine. "Integrated dockside charging was the right first step because it made the system easier to use without requiring specialized charging installations. By further optimizing the PDU for manufacturing, we are advancing a key part of the E-Motion™ architecture that may support future charging configurations as the platform continues to evolve."

Together with the ongoing validation of its refined Octillion battery packs, the PDU manufacturability work is intended to support a more production-ready E-Motion™ architecture. Vision Marine has not announced commercial availability of fast-charging functionality, and any future higher-output charging capability remains subject to engineering validation, battery and PDU compatibility, infrastructure availability, safety requirements and commercialization decisions.

Vision Marine intends to continue advancing the E-Motion™ platform through component manufacturability, battery integration, charging compatibility, data, diagnostics, display and service-related development initiatives designed to improve system functionality, support OEM integration and enhance the customer experience.
