35 ILLUSTRATIVE PROLOGIUM CELL UNIT ECONOMICS At Run-Rate Production UNIT ECONOMICS ILLUSTRATIVE EST COMMENTARY CELL REVENUE Average Selling Price(1) $250 -$320 US$/kWh The illustrative unit revenue range is based on management’s internal expectations of segment sales over time. Management expects that with increased production capacity, the Company will have the opportunity to expand sales to mass market auto and other segments in which competitors have already achieved economies of scale with existing technology applications COST OF GOODS SOLD Excluding D&A $150 -$220 US$/kWh The illustrative unit cost of goods sold includes cell input material, direct & indirect labor, non-material variable costs, fixed costs as well as packing costs. The expansion of production capacity from 0.55GWh/yr to ~5GWh/yr with the completion of Dunkirk Phase I provides the opportunity for non-material COGS to significantly decline with further economies of scale realized as expansion capacity is executed upon GROSS MARGIN % 20% -40% Illustrative future gross margin estimates reflect a mix of industrial benchmarks as well as an assumption of continued technical performance improvements, supporting a mix of premium and high-performance segment sales in addition to mass market automotive sales Note: The economics presented here are not projections, but based on today’s expected production, future customer profiles and market conditions. Represents Company’s targeted breakdown of customer market segments at run-rate following initial Phase of Dunkirk manufacturing facility. (1) Average Selling Price is a volume-weighted average across all market segments, calculated as total target revenue divided bytotal target sales volume. Total target sales volume is derived from the aggregate designed capacity of manufacturing facilities that the Company currently expects could be developed by 2032 under its current capital expenditure plan. Total target revenue is calculated by applyingthe average selling price for each market segment to the sales volume for that segment, based on the market-segment composition shownonPage 17. The market-segment composition and segment-specific average selling prices are based on independent third-party data. Actual production capacity, sales volumes, market-segment composition, pricing and revenue may differ materially due to changes in capital expenditure plans, financing availability, costs, production ramp-up, utilization, yield, customer demand, supply-chain conditions, taxes, laws and regulations and other factors. The Average Selling Price is a volume-weighted average price, calculated by dividing total revenues by total volumes. These revenues and volumes are targets following initial Phase of Dunkirk, aggregated across all market segments. Prices vary significantly across differentmarket segments.

About Prologium Holding Inc.

Founded in 2006, Prologium Holding Inc. (“ProLogium”) is an energy innovation company dedicated to the development and manufacturing of next-generation lithium ceramic batteries, holding over 1,100 global patents (granted and pending). In 2013, ProLogium commercialized solid-state batteries, primarily for use in smartphones charging cases and since then, ProLogium has delivered in the aggregate more than 2.4 million battery products to its collaboration partners and customers, including cells used in automotive audio systems and approximately 10,000 samples for automotive applications. In 2025, ProLogium introduced superfluidized inorganic next generation lithium ceramic battery, integrating the advantages of solid-state and liquid type batteries and redefining next-generation battery technology with scalable manufacturability and cost competitiveness. In 2026, ProLogium once again received the Edison Awards Gold Award for its superfluidized inorganic next generation lithium ceramic battery technology.

With more than 13 years of manufacturing know-how, ProLogium is among the first companies to successfully commercialize a high-efficiency roll-to-roll coated ceramic separator manufacturing process and its Taoke facility announced that it was the first commercial next-generation lithium ceramic battery gigafactory to publicly display the production line—reflecting that next generation lithium ceramic batteries represent a feasible solution for scalable manufacturing rather than a laboratory project. ProLogium’s first GWh-class gigafactory, Taoke facility, is located in Taoyuan, Taiwan. In 2024, ProLogium established its first overseas R&D center in Paris-Saclay, France, providing customized technical support for the European market. ProLogium’s second battery gigafactory is located in Dunkirk, France, where groundbreaking for its Phase 1 facility took place in February 2026 and the project is proceeding to the detailed design and construction stage. The Phase 1 facility will have a designed production capacity of 4.0 GWh when complete, which ProLogium expects to achieve gradually by 2030. The Dunkirk facility site will have a maximum designed production capacity of 44.0 GWh and is intended to work closely with ProLogium’s Paris-Saclay R&D center.
