"During the first quarter, we maintained our pace of delivering on key operational and capital allocation objectives, including forming the joint venture to support our San Ciprián operations and repositioning debt in Australia," said Alcoa President and CEO William F. Oplinger. "A positive aluminum market led to stronger results for the first quarter, while we continued to focus on safety, stability, and operational excellence amidst economic uncertainty."

First Quarter 2025 Results

Production: Alumina production decreased 1 percent sequentially to 2.35 million metric tons. In the Aluminum segment, production decreased 1 percent sequentially to 564,000 metric tons primarily due to two fewer days in the period, partially offset by continued progress on the Alumar, Brazil smelter restart.
Shipments: In the Alumina segment, third-party shipments of alumina decreased 8 percent sequentially primarily due to timing of shipments and decreased trading. In Aluminum, total shipments decreased 5 percent sequentially primarily due to the absence of Ma'aden offtake volumes and timing of shipments.
Revenue: The Company's total third-party revenue of $3.4 billion decreased 3 percent sequentially. In the Alumina segment, third-party revenue decreased 8 percent on lower shipments, unfavorable currency impacts, and a decrease in average realized third-party price, partially offset by higher volumes and price from bauxite offtake and supply agreements. In the Aluminum segment, third-party revenue was flat on an increase in average realized third-party price, partially offset by lower shipments after strong fourth quarter 2024 results.
Net income attributable to Alcoa Corporation was $548 million, or $2.07 per common share. Sequentially, the results reflect increased aluminum prices, a net benefit from lower alumina prices, and higher volumes and price from bauxite offtake and supply agreements, partially offset by lower shipments and tariff costs on imported aluminum. Additionally, the results reflect the non-recurrence of a restructuring charge of $82 million related to the Kwinana refinery curtailment and unfavorable currency impacts of $51 million in the fourth quarter 2024.

In the first quarter 2025, Alcoa incurred approximately $20 million of tariff costs on imports of aluminum from Canada as the 25 percent tariff under U.S. Section 232 became effective on March 12, 2025.

Adjusted net income was $568 million, or $2.15 per common share, excluding the impact from net special items of $20 million. Notable special items include $12 million of debt settlement expenses.
Adjusted EBITDA excluding special items was $855 million, a sequential increase of $178 million primarily due to higher aluminum prices, a net benefit from lower alumina prices, and higher volumes and price from bauxite offtake and supply agreements, partially offset by lower shipments and tariff costs on imported aluminum.

Production costs in the Alumina segment decreased primarily due to the non-recurrence of a charge to write down certain inventories to their net realizable value in the fourth quarter 2024. Production costs in the Aluminum segment increased primarily due to the non-recurrence of the full year 2023 and 2024 benefit of $30 million related to Section 45X of the Inflation Reduction Act recorded in the fourth quarter 2024.

Cash: Alcoa ended the quarter with a cash balance of $1.2 billion. Cash provided from operations was $75 million. Cash provided from financing activities was $77 million primarily related to the repositioning of debt. Cash used for investing activities was $108 million primarily due to capital expenditures of $93 million.
Working capital: For the first quarter, Receivables from customers of $1.2 billion, Inventories of $2.2 billion and Accounts payable, trade of $1.6 billion comprised DWC working capital. Alcoa reported 47 days working capital, a sequential increase of 13 days. Inventory days increased due to higher raw materials prices and volumes mainly in the Alumina segment and timing of aluminum shipments. Additionally, accounts payable days decreased on lower alumina trading.

Key Actions

Tariffs: Throughout the first quarter 2025, Alcoa actively engaged with administrations, governments, and policy makers in the U.S. and globally regarding the impact of tariffs on trade flows and the importance of primary aluminum to the U.S. economy through the deeply integrated aluminum supply chain. Additionally, the Company engaged with customers, suppliers and logistics companies to avoid supply disruption.
Debt repositioning: On March 17, 2025, the Company completed an offering of $500 million aggregate principal amount of 6.125 percent senior notes due in 2030 and an offering of $500 million aggregate principal amount of 6.375 percent senior notes due in 2032. The notes were issued by a wholly-owned subsidiary, Alumina Pty Ltd, incorporated in Australia. Net proceeds of $985 million from the issuances were primarily used to settle $609 million aggregate principal amount tendered and accepted for purchase of outstanding 5.500 percent senior notes due 2027 and $281 million aggregate principal amount tendered and accepted for purchase of outstanding 6.125 percent senior notes due 2028.
San Ciprián operations: On April 1, 2025, Alcoa announced the formation of a joint venture between Alcoa and IGNIS Equity Holdings, SL (IGNIS EQT) to support the continued operation of the San Ciprián complex. Under the joint venture agreement, effective March 31, 2025, Alcoa owns a 75 percent interest and continues as the managing operator and IGNIS EQT owns a 25 percent interest. Alcoa and IGNIS EQT contributed $81 (€75) million and $27 (€25) million, respectively, to form the joint venture and fund the operations. Additionally, up to $108 (€100) million may be funded by Alcoa as needed for operations with a priority position in future cash returns. The joint venture agreement allows for the planned restart of the San Ciprián smelter in 2025, a commitment made within the Viability Agreement signed with the employees when the smelter was curtailed in 2021 due to exorbitant energy costs.

2025 Outlook

The following outlook does not include 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, the Company is unable to address the probable significance of the unavailable information, which could be material to future results.

Alcoa expects 2025 total Alumina segment production and shipments to remain unchanged from its prior projection, ranging between 9.5 to 9.7 million metric tons, and between 13.1 and 13.3 million metric tons, respectively. The difference between production and shipments reflects trading volumes and externally sourced alumina to fulfill customer contracts due to the curtailment of the Kwinana refinery.

Alcoa expects 2025 total Aluminum segment production and shipments to remain unchanged from its prior projection, ranging between 2.3 and 2.5 million metric tons, and between 2.6 and 2.8 million metric tons, respectively.

Within the second quarter 2025 Alumina Segment Adjusted EBITDA, the Company expects to maintain the strong level of performance delivered in the first quarter 2025.

For the second quarter 2025, the Aluminum Segment expects sequential unfavorable impacts of $90 million due to U.S. Section 232 tariffs on imports of aluminum from Canada, and $15 million of restart costs for the San Ciprián smelter. Alumina costs in the Aluminum segment are expected to be favorable by $165 million sequentially.

The Company expects Other expenses for the second quarter 2025 to increase approximately $10 million sequentially due to equity investment losses.

Based on current alumina and aluminum market conditions, Alcoa expects second quarter 2025 operational tax benefit to approximate $50 million to $60 million, which may vary with market conditions and jurisdictional profitability.

Non-GAAP Financial Measures

This news release contains reference to certain financial measures that are not calculated and presented in accordance with generally accepted accounting principles in the United States (GAAP).

Net income (loss) attributable to Alcoa Corporation common shareholders – as adjusted	$	2.15	$	1.04		$	(0.81	)

Net income (loss) attributable to Alcoa Corporation – as adjusted and Diluted EPS – as adjusted are non-GAAP financial measures. Management believes these measures are meaningful to investors because management reviews the operating results of Alcoa Corporation excluding the impacts of restructuring and other charges, various tax items, and other special items (collectively, "special items"). There can be no assurances that additional special items will not occur in future periods. To compensate for this limitation, management believes it is appropriate to consider Net income (loss) attributable to Alcoa Corporation and Diluted EPS determined under GAAP as well as Net income (loss) attributable to Alcoa Corporation – as adjusted and Diluted EPS – as adjusted.

⁽¹⁾		Other special items include the following:
		for the quarter ended March 31, 2025, a charge for debt settlement expenses ($12), a net favorable change in mark-to-market energy derivative instruments ($5), external costs related to portfolio actions ($3), costs related to the restart process at the San Ciprián, Spain smelter ($2), and a benefit for other special items ($1); for the quarter ended December 31, 2024, a net favorable change in mark-to-market energy derivative instruments ($23), an adjustment to the gain on sale of the Warrick Rolling Mill in Evansville, Indiana for additional site separation costs ($17), external costs related to portfolio actions ($4), and net charges for other special items ($1); and, for the quarter ended March 31, 2024, an adjustment to the gain on sale of the Warrick Rolling Mill in Evansville, Indiana for additional site separation costs ($11), a net unfavorable change in mark-to-market energy derivative instruments ($4), external costs related to portfolio actions ($4), costs related to the restart process at the Warrick Operations site in Indiana ($3), costs related to the restart process at the San Ciprián, Spain smelter ($2), and a net benefit for other special items ($2).
⁽²⁾		Discrete and other tax items are generally unusual or infrequently occurring items, changes in law, items associated with uncertain tax positions, or the effect of measurement-period adjustments and include the following:
		for the quarter ended March 31, 2025, a net charge for discrete tax items ($2); and, for the quarter ended December 31, 2024, a net charge for discrete tax items ($1).
⁽³⁾		The tax impact on special items is based on the applicable statutory rates in the jurisdictions where the special items occurred. The noncontrolling interest impact on special items represents Alcoa's partner's share of certain special items.

⁽⁴⁾		In any period with a Net loss attributable to Alcoa Corporation (GAAP or as adjusted), the average number of common shares applicable to diluted earnings per share exclude certain share equivalents as their effect is anti-dilutive.

		For the quarter ended March 31, 2025, undistributed earnings of $9 and undistributed earnings – as adjusted of $9 were allocated to preferred stock under the two-class method. For the quarter ended December 31, 2024, dividends paid on preferred stock were $1, and undistributed earnings of $2 and undistributed earnings – as adjusted of $3 were allocated to preferred stock under the two-class method.

Adjusted EBITDA, excluding special items	$	855		$	677	$	132

Alcoa Corporation's definition of Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) is net margin plus an add-back for depreciation, depletion, and amortization. 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 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.

⁽¹⁾		Special items include the following (see reconciliation of Adjusted Income above for additional information):
		for the quarter ended March 31, 2025, the mark-to-market contracts associated with the Portland smelter generated gains ($2) in Other (income) expenses, net which economically offset a portion of the cost of power recorded in Cost of goods sold. This non-GAAP reclass presents the net cost of power within Cost of goods sold. This was in addition to external costs related to portfolio actions ($3) and costs related to the restart process at the San Ciprián, Spain smelter ($2); for the quarter ended December 31, 2024, total cost of power associated with the Portland smelter ($4). This was offset by external costs related to portfolio actions ($4) and charges for other special items ($2); and, for the quarter ended March 31, 2024, external costs related to portfolio actions ($4), costs related to the restart process at the Warrick Operations site in Indiana ($3), costs related to the restart process at the San Ciprián, Spain smelter ($2), and a benefit for other special items ($1).

Capital expenditures		(93	)		(169	)		(101	)

Free cash flow	$	(18	)	$	246		$	(324	)

Free Cash Flow is a non-GAAP financial measure. Management believes this measure is meaningful to investors because management reviews cash flows generated from operations after taking into consideration capital expenditures, which are necessary to maintain and expand Alcoa Corporation's asset base and are expected to generate future cash flows from operations. It is important to note that Free Cash Flow does not represent the residual cash flow available for discretionary expenditures since other non-discretionary expenditures, such as mandatory debt service requirements, are not deducted from the measure.

Net debt	$	1,491	$	1,457

Net debt is a non-GAAP financial measure. Management believes 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 (net cash)	$	2,066	$	—	$	2,066	$	2,057	$	—	$	2,057

Net debt is a non-GAAP financial 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⁾		Cash balances attributable to Noncontrolling interest were excluded as the impact was immaterial.

DWC working capital and Days working capital are non-GAAP financial measures. Management believes that these measures are meaningful to investors because management uses its working capital position to assess Alcoa Corporation's efficiency in liquidity management.

⁽¹⁾		Days working capital is calculated as DWC working capital divided by the quotient of Sales and number of days in the quarter.
