Investor Presentaiton

BATTERY-GRADE MANGANESE MARKET Manganese-rich cathodes provide substantial cost, performance and sustainable sourcing benefits Committed government policies are expected to underpin a near six-fold increase in North American EV penetration levels by 2030 We expect manganese-rich battery chemistries to capture ~30% of the market by 2030, and >50% by 2040 EV (passenger car and commercial vehicle) penetration rates(a)(b)(c)(d) Electric vehicle battery chemistries Active cathode materials, % by mass 50% EV penetration in North America by 2030 100% 2021 2022 2023 2024 2025 2030 2040 2050 North America NEV Penetration Rate ROW NEV Penetration Rate Source: South32 analysis Notes: a. b. C. EV penetration is calculated as EV production divided by total automobile production. d. NEV (new electric vehicles) includes plug-in hybrids, battery EVs and hydrogen fuel-cell passenger cars Passenger car and commercial vehicles include commercial trucks/SUVS. North America refers to US, Canada and Mexico. e. Based on prices as at the end of 2022.
