Alcoa — Jan 22, 2025 release

Within the first quarter 2025 Alumina Segment Adjusted EBITDA, the Company expects sequential favorable impacts of $30 million due to the absence of a charge to write down certain inventories to their net realizable value, partially offset by the typical first quarter impacts from the beginning of maintenance cycles and lower shipments. For the first quarter 2025, the Aluminum Segment expects sequential unfavorable impacts of $60 million due to the non-recurrence of the fourth quarter 2024 benefit from the IRA 45X credit, lower seasonal pricing at Brazil hydro-electric facilities, and the absence of Ma’aden offtake volumes due to the announced transaction. Within Other expenses, contributions to ELYSIS TM in the first quarter of 2025 are expected to increase by $25 million which triggers loss recognition. Based on current alumina and aluminum market conditions, Alcoa expects first quarter 2025 operational tax expense to approximate $120 million to $130 million, which may vary with market conditions and jurisdictional profitability.
