Rapidly growing demand for a critical mineral 4N+ HPA Market 17 Favourable Supply-Demand Forecast…1 • Market demand for HPA is driven by growth in LEDs, lithium-ion battery coatings, micro-LEDs and synthetic sapphire glass. • CRU forecast total 4N+ HPA demand in 2024 of 46,463 tonnes, reaching 139,731 tonnes in 2030, representing a CAGR of 20.1%. • Based on CRU forecasts for 4N+ HPA, a supply shortfall of 7.6kt is expected to develop in 2028, growing to a supply shortfall of 78kt in 2030, representing 127% of estimated production. …Driving Increase in Forecast Prices for 4N+ HPA1,2 • No benchmark pricing. Akin to kaolin, pricing is determined on the value of a given HPA product for a particular end-use application. • Forecast ranges for nominal prices can therefore be wide. o CRU estimates USD20.70/kg price in 2025, rising to USD31.13 in 2030 at an 8.5% CAGR (2025-2030); and, o FutureBridge estimates USD30.70/kg price in 2025, rising to USD39.20 in 203
