REC Silicon Investor Presentation

Pareto Investor Conference | Battery REC well positioned to supply global market with silicon gases REC Silicon Moses Lake, WA SiH4 Silane production capacity: ~25,000 tons per year Highest purity & lowest cost Hydroelectricity = low carbon footprint REC Silicon Moses Lake REC Silicon Butte Next Generation Silicon Anode Manufacturing Moses Lake, WA › Largest producer and distributor of Silane Gas > Unmatched experience and safety record › Recognized product quality and reliability > ~70% Semiconductor market share Silicon Anode Materials Cell/ Battery manufacturing > Infrastructure to protect market share › Large module fleet Co-location is Necessary > Secure distribution channels > > Current silane distribution network +/-7,000 MT/yr. Distribution capacity expansion capex ~$30M per 1,000MT › Available capacity to support market growth Moses Lake and Butte are the only existing silane plants in the US and Europe. Total capacity of 32,000 MT silane which is enough silicon for batteries for 2.5M EVs at current silane-based silicon anode performance. Reduces to ~1M EVs as silicon content increases in the battery. O REC Silicon ASA. All rights reserved. Confidential RECSILICON
