The Company's technology is engineered to operate at the cell level, diagnosing imbalances and dynamically reallocating charge and discharge across battery strings to restore usable capacity and improve system performance. As previously disclosed, independent validation conducted by the National Research Council of Canada demonstrated the technology's ability to recover nearly all lost capacity attributable to cell imbalance, reinforcing its potential applicability across a wide range of battery systems.

The Company's PCT patent application includes innovations relating to a method and system for battery pack adjustment, designed to address the common issue of cell imbalance within battery packs, which can lead to reduced capacity, performance limitations, and shortened lifespan. The technology introduces an intelligent system that monitors and manages the state of charge across groups of cells, enabling more balanced operation and improved utilization of available energy. By dynamically reallocating charge and discharge across cells, the system is designed to restore usable capacity, enhance safety, and extend overall battery life.

The PCT patent application also includes innovations relating to two-wire charging and remote voltage detection, which are designed to simplify battery system architecture and reduce hardware complexity. This approach enables both charging and voltage measurement to be performed using a single pair of wires, eliminating the need for additional sensing components typically required in conventional systems. The result is a more streamlined and cost-efficient solution that maintains reliable performance while supporting scalable deployment across electric vehicle and energy storage applications.

Intellectual Property as a Strategic Enabler of Platform Scale

The PCT patent application is intended to protect a suite of integrated innovations spanning both hardware and software, including intelligent energy management systems, real-time diagnostic architectures, and streamlined methodologies for voltage detection and system optimization. Collectively, these components form the basis of a technology platform designed not as a single-point solution, but as an embedded layer within the broader battery lifecycle, capable of integrating into existing infrastructure and supporting next-generation service models.

The Company views intellectual property as a strategic enabler of platform scale, ecosystem integration, and long-term value creation. By advancing global patent protection through the PCT framework, Battery X Metals is positioning its technology to support licensing models, strategic commercial partnerships, and integration across distributed service environments, including automotive service centers, dealership networks, and fleet maintenance ecosystems. This approach also supports potential future expansion into adjacent applications such as stationary energy storage systems, while enabling the development of a broader data-driven battery intelligence layer as deployment scales.

Positioning for the Emerging Post-Warranty EV Market

The global transition toward electrification continues to accelerate, with the installed base of lithium-ion batteries expanding rapidly across electric vehicles and energy storage systems. As a growing proportion of this fleet approaches or exits manufacturer warranty coverage, demand is expected to increase for solutions that can extend battery lifespan, improve performance, and reduce total cost of ownership. Battery X Metals is advancing its rebalancing technology as a targeted solution within this emerging market, with the objective of enabling scalable, service-based intervention that addresses battery degradation at its source.

The Company believes that securing a robust intellectual property position at this stage is critical to participating meaningfully in this market opportunity, while supporting future integration with diagnostic platforms, service workflows, and recurring revenue models. The PCT patent application aligns with the Company's broader strategy of transitioning from a discrete technology provider toward a platform-oriented participant in the global battery lifecycle ecosystem.

Advancing Toward Commercialization and Scalable Deployment

The PCT patent application is aligned with the Company's ongoing efforts to advance its technology toward commercialization, including continued development of next-generation hardware systems, refinement of diagnostic capabilities, and evaluation of deployment models across service networks. As part of its broader platform strategy, Battery X Metals intends to integrate its rebalancing technology within a structured ecosystem that may include diagnostic front-end solutions, service workflows, and data-driven performance analytics, supporting a scalable and repeatable model for battery lifecycle management.

"This International PCT patent application represents a foundational step in establishing a globally defensible intellectual property position for our technology," said Massimo Bellini Bressi, Chief Executive Officer of Battery X Metals. "We are building a platform designed to operate within the rapidly expanding battery ecosystem, and securing global intellectual property protection is essential to enabling long-term commercialization, strategic partnerships, and scalable deployment across markets, in an industry rapidly growing, worldwide."

The Problem: Rising EV Adoption Presents New Battery Lifecycle Challenges

In 2024, global EV sales reached approximately 17.1 million units, representing a 25% increase from 2023¹. With cumulative global EV sales from 2015 to 2023 totaling an estimated over 40 million units², a significant share of the global EV fleet is expected to exit warranty coverage over the coming years.

By 2031, nearly 40 million electric, plug-in hybrid, and hybrid vehicles worldwide are anticipated to fall outside of their original warranty coverage^3,4. This projection is based on current EV adoption figures and standard industry warranty terms, and underscores a growing risk for EV owners facing battery degradation, reduced capacity, and costly replacement requirements⁵. As the global EV fleet continues to expand, the demand for technologies that extend battery life, reduce long-term ownership costs, and support a sustainable transition to electric mobility is increasing.

The Solution: Pioneering Next-Generation Technologies to Support Lithium-Ion Battery Longevity

Battery X Rebalancing Technologies' proprietary software and hardware technology aims to address this challenge by extending the lifespan of EV batteries. This innovation is being developed with the aim to enhance the sustainability of electric transportation and the goal to provide EV owners with a more cost-effective, environmentally friendly ownership experience by reducing the need for costly battery replacements.

Battery X Rebalancing Technologies' rebalancing technology, validated by the National Research Council of Canada ("NRC"), focuses on battery cell rebalancing. The NRC validation demonstrated the technology's ability to effectively correct cell imbalances in lithium-ion battery packs, recovering nearly all lost capacity due to cell imbalance. The validation was conducted on battery modules composed of fifteen 72Ah LiFePO₄ cells connected in series. The cells were initially balanced to a uniform state of charge (SOC), with a measured discharge capacity of 71.10Ah. In the validation test, three of the fifteen cells were then artificially imbalanced-one cell was charged to a 20% higher SOC, and two cells were discharged to a 20% lower SOC-resulting in a reduced discharge capacity of 46.24Ah, representing a decrease of approximately 35%. Following rebalancing using Battery X Rebalancing Technologies' rebalancing technology, the battery module's discharge capacity was restored to 70.94Ah, representing the recovery of approximately 99% of the capacity lost due to cell imbalance.

These advancements establish Battery X Rebalancing Technologies as a participant in lithium-ion and EV battery solutions, aiming to tackle the critical challenges of capacity degradation of battery packs and expensive replacements. By extending the lifecycle of battery materials within the supply chain, Battery X Rebalancing Technologies aims to support the energy transition and promote a more sustainable future.
