3 Important information Non-GAAP Financial Measures This presentation contains reference to certain financial measures that are not calculated and presented in accordance with generally accepted accounting principles in the United States (GAAP). Alcoa Corporation believes that the presentation of these non-GAAP financial measures is useful to investors because such measures provide both additional information about the operating performance of Alcoa Corporation and insight on the ability of Alcoa Corporation to meet its financial obligations by adjusting the most directly comparable GAAP financial measure for the impact of, among others, “special items” as defined by the Company, non-cash items in nature, and/or nonoperating expense or income items. The presentation of non-GAAP financial measures is not intended to be a substitute for, and should not be considered in isolation from, the financial measures reported in accordance with GAAP. Certain definitions, reconciliations to the most directly comparable GAAP financial measures and additional details regarding management’s rationale for the use of the non-GAAP financial measures can be found in the appendix to this presentation. Alcoa Corporation does not provide reconciliations of the forward-looking non-GAAP financial measures Adjusted EBITDA and Adjusted Net Income, including transformation, intersegment eliminations and other corporate Adjusted EBITDA; operational tax expense; and other expense; each excluding special items, to the most directly comparable forward-looking GAAP financial measures because it is impractical to forecast certain special items, such as restructuring charges and mark-to-market contracts without unreasonable efforts due to the variability and complexity associated with predicting the occurrence and financial impact of such special items. For the same reasons, we are unable to address the probable significance of the unavailable information, which could be material to future results.

41 Items expected to impact Adjusted EBITDA and Adjusted net income for 2Q25 Additional business considerations Expected sequential impacts on Adjusted EBITDA excluding special items, excluding indexed sales prices or currency impacts: ▪ We expect the Alumina segment to maintain strong level of performance delivered in the first quarter. ▪ We expect Aluminum segment performance to be unfavorable by approximately $105 million due to U.S. Section 232 tariff on imports of aluminum from Canada (approximately $90 million), and San Ciprian smelter restart costs (approximately $15 million). ▪ Alumina costs in the Aluminum segment are expected to be favorable by $165 million. ▪ Estimate intersegment profit elimination for every $10/mt decrease in API prices to be a $7 million to $9 million favorable impact based on comparison of the average API of the last two months of each quarter (API is based on average of prior month spot prices). − Due to current market volatility, intersegment profit impacts are expected to be at the low end of the sensitivity range. ▪ Using quarter end exchange rates, 1Q25 Adjusted EBITDA included a favorable balance sheet revaluation impact of approximately $6 million (unfavorable $15 million sequentially compared to 4Q24); impacts related to balance sheet revaluation are not incorporated into the currency sensitivities provided for Adjusted EBITDA. Below Adjusted EBITDA: ▪ Other expenses are expected to increase in 2Q25 by approximately $10 million primarily due to equity investment losses. Other expenses in 1Q25 included favorable foreign currency gains of approximately $20 million, which may not recur. ▪ Based on recent pricing, the Company expects 2Q25 operational tax benefit to approximate $50 million to $60 million, which includes timing and catchup adjustments related to lower alumina prices.

Net margin is equivalent to Sales minus the following items: Cost of goods sold; Selling, general administrative, and other expenses; Research and development expenses; and Provision for depreciation, depletion, and amortization. Adjusted EBITDA is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because Adjusted EBITDA provides additional information with respect to Alcoa Corporation’s operating performance and the Company’s ability to meet its financial obligations. The Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies.

Management believes that these measures are meaningful to investors because management reviews cash flows generated from operations after taking into consideration capital expenditures and net distributions to noncontrolling interest. Capital expenditures are necessary to maintain and expand Alcoa Corporation’s asset base and are expected to generate future cash flows from operations, while net distributions to noncontrolling interest are necessary to fulfill our obligations to our joint venture partners. It is important to note that Free cash flow and Free cash flow less net distributions to noncontrolling interest do not represent the residual cash flows available for discretionary expenditures since other non-discretionary expenditures, such as mandatory debt service requirements, are not deducted from the measure.

Management believes that this measure is meaningful to investors because management assesses Alcoa Corporation’s leverage position after considering available cash that could be used to repay outstanding debt. When cash exceeds total debt, the measure is expressed as net cash. Adjusted net debt and Proportional adjusted net debt are also non-GAAP financial measures. Management believes that these additional measures are meaningful to investors because management also assesses Alcoa Corporation’s leverage position after considering available cash that could be used to repay outstanding debt and net pension/OPEB liability, net of the portion of those items attributable to noncontrolling interest (NCI). 1.
