let casthouse at Grundartangi (the “Casthouse Project”). The new billet casthouse has the capacity to produce 150,000 tonnes of value-added billet. The Casthouse Project will also increase Grundartangi’s annual capacity to produce value-added primary foundry alloys from 60,000 tonnes of capacity to 120,000 tonnes of capacity. This incremental billet and primary foundry alloy capacity displaces standard-grade ingot production, raising expected total value-added product premiums for Grundartangi products. The billet produced at the Grundartangi casthouse is expected to be Natur-AlTM  branded billet, our low-carbon aluminum brand.

Holly has an annual production capacity of approximately 230,000 tonnes of primary aluminum. In December 2020, we began a multi-year project to restore previously curtailed capacity at Mt. Holly. The initial phase was completed in 2022 and returned annual active production capacity to approximately 172,000 MT per annum (75% of capacity). Any potential future restart of Mt. Holly's curtailed capacity will be made in the context of then-current market conditions
