Cost per kilogram is expected to decline as production scales from pilot to commercial Path to Cost Leadership Drivers of Cost Reduction Illustrative Electrolyte Cost per Kilogram Cost per kg Pilot Batch 30 MT (Current) Pilot Continuous 45 MT* (Once completed) Pre-Commercial 500 MT ~1 GWh Early Commercial 2,000 MT ~4 GWh Full Commercial 20,000 MT ~40 GWh *Total Thornton expected capacity is 75 MT/y, combining the 30 MT batch and 45 MT continuous lines. Illustrative only. The curve shows expected direction, not magnitude, and is not a forecast of cost, price, timing or output. Battery production equivalents assume 0.5 kg of electrolyte per kWh. Most significant cost reductions expected at pilot continuous and pre-commercial stages Raw Material Costs Lower precursor costs through supplier scale-up and strategic sourcing Continuous Manufacturing Improved efficiency, throughput, and quality versus batch production Economies of Scale Higher volumes reduce fixed costs per unit and increase purchasing leverage Process Yield Higher yields reduce material consumption, waste, and unit costs Strategic Partnerships Collaboration accelerates scale and strengthens cost competitiveness 14
