Technology Development / Battery Platform Expansion

Scaling E-Motion™ Reach: U.S.-based battery manufacturer Octillion delivers advanced high-density sample packs, supporting higher-output capability, flexible configurations, and broader OEM evaluation opportunities for E-Motion™ marine applications.

Advancing Capacity & Integration: Vision Marine begins physical validation of custom Octillion sample packs that provide approximately 7.5% more energy capacity per module, with a similar volumetric footprint as the previous generation.

Advancing Integration Validation: Immediate mechanical and electrical validation of these refined packs supports the next phase of product validation and may help inform future commercial applications across vessel classes.

BOISBRIAND, QC , June 2, 2026 /PRNewswire/ -- Vision Marine Technologies Inc. (NASDAQ: VMAR) (TSXV: VMAR) ("Vision Marine" or the "Company"), a company specializing in high-voltage marine propulsion and a vertically integrated multi-brand boat retail and service platform, today announced that it has received the first two physical battery packs built from a refined high-voltage design developed with Octillion Power Systems Inc. ("Octillion") of California for integration into Vision Marine's E-Motion™ electric marine propulsion platform.

"We are pleased to continue advancing this work with Octillion," commented Maxime Poudrier, Chief Operating Officer at Vision Marine. "Their engineering capabilities and production experience, particularly proven in the marine space, are important to our platform strategy. This battery advancement supports our objective of making high-voltage electric propulsion more adaptable for manufacturers, more practical for consumers and commercial operators, and better aligned with the real-world demands of boating applications."

The receipt of these first two packs marks a concrete integration milestone for the updated battery design and enables Vision Marine to begin the next stage of physical validation within its E-Motion™ architecture. This refined battery design provides approximately 7.5% more energy capacity per pack within a similar volumetric footprint compared with the Company's prior battery configuration. Output capability, vessel-level performance, charging compatibility, and integration parameters remain subject to the Company's ongoing validation process.

These performance and structural benchmarks are advancing with electrochemistry, advanced thermal management, and domestic manufacturing footprint, supporting continued development of the refined E-Motion™ platform. Octillion brings a proven pedigree of engineering safe, high-voltage battery architectures deployed across demanding mobility environments worldwide. Through this technical collaboration, Vision Marine's E-Motion™ platform can thrive amidst the intense mechanical vibrations, radical thermal swings, and moisture infiltration unique to challenging maritime operations.

Vision Marine believes this advancement may support more flexible electric propulsion configurations across a broader range of recreational boat models. Depending on vessel requirements, the architecture may also support single-pack applications for smaller boats, while also improving energy density from one- to three-pack configurations by providing more kWh capacity within a similar weight and packaging profile.

"This is an important technology advancement with direct market application," continued Poudrier. "Receiving the first two sample packs built from this refined design allows us to move into the next stage of integration validation. By increasing capacity and output within a similar footprint, this battery design may allow us to address a broader range of recreational and commercial boat models, from smaller platforms to multi-pack configurations requiring greater total energy capacity. For manufacturers, it will provide greater flexibility to evaluate E-Motion™ where space, weight, performance, and price positioning are critical."

The next stage of integration and validation is expected to include mechanical fitment, electrical communication testing, discharge validation, thermal review, charging compatibility assessment, and vessel-level integration work within the E-Motion™ architecture.

Vision Marine believes the new battery design supports its broader strategy of developing a scalable electric propulsion platform that can serve multiple recreational boating categories. Through its E-Motion™ technology, OEM relationships, integration expertise, and Nautical Ventures retail and service platform, Vision Marine continues to build the technical and commercial infrastructure intended to support broader electric boating adoption.
