"During the third quarter, we advanced the AliGroup acquisition, delivered improved refinery performance, and increased production across our smelting portfolio," said Alcoa President and CEO William F. Oplinger. "As we look ahead, we remain focused on strengthening safety performance, sustaining operational stability, and building on this momentum as we work toward closing the AliGroup acquisition in the first half of 2027."

Third Quarter 2026 Results

Production: Alumina production increased 11 percent sequentially to 2.5 million metric tons primarily due to improved stability at the Pinjarra, Australia refinery. In the Aluminum segment, production increased 2 percent sequentially to 649,000 metric tons primarily due to capacity restarts completed in the second quarter 2026 and the completion of the Alumar smelter restart in the third quarter 2026.
Shipments: In the Alumina segment, third-party shipments of alumina increased 2 percent sequentially primarily due to higher production. In Aluminum, total shipments decreased 5 percent sequentially following elevated second quarter 2026 shipment volumes associated with first quarter inventory repositioning.
Revenue: The Company generated third-party revenue of $3.7 billion, a 7 percent sequential decrease. Alumina segment third-party revenue increased 7 percent, supported by higher average realized alumina prices and shipments. Aluminum segment third-party revenue reflected lower shipments and average realized prices, resulting in a 9 percent sequential decrease.
Net income attributable to Alcoa Corporation was $483 million, or $1.81 per share. Sequentially, the results reflect favorable mark-to-market changes on the Saudi Arabian Mining Company (Ma’aden) shares and energy contracts, improved production costs, and higher alumina prices, partially offset by lower aluminum prices and shipments.
Adjusted net income attributable to Alcoa Corporation was $485 million, or $1.82 per share, excluding the impact from net special items of $2 million. Notable special items include mark-to-market gains on energy contracts of $32 million, a mark-to-market gain on the Ma’aden shares of $28 million, demolition and remediation costs at closed locations of $25 million, and external costs related to the AliGroup acquisition of $14 million.
Adjusted EBITDA excluding special items was $789 million, as improved production costs in both the Aluminum and Alumina segments and higher alumina prices were more than offset by lower aluminum prices and shipments, resulting in a sequential decrease of $112 million.
Cash: Cash provided from operations was $643 million. Cash provided from financing activities was $2.6 billion, reflecting financing obtained for the AliGroup acquisition. Cash used for investing activities was $183 million, including capital expenditures of $171 million. Free cash flow was $472 million. Alcoa ended the quarter with a cash balance of $4.4 billion.
Working capital: For the third quarter, Receivables from customers of $1.3 billion, Inventories of $2.6 billion and Accounts payable, trade of $1.9 billion comprised DWC working capital. Alcoa reported 50 days working capital, reflecting a sequential increase of 4 days primarily on an increase in inventory days due to higher aluminum volumes. Days working capital was consistent with the third quarter 2025.

Key Actions

AliGroup acquisition:
- During the third quarter 2026, Alcoa continued to advance the AliGroup acquisition, progressing regulatory approvals as well as transition and integration planning. On October 15, 2026, South32 shareholders approved the acquisition. The transaction remains on track to close in the first half of 2027.
- On September 23, 2026, Alcoa completed offerings of $1.5 billion aggregate principal amount of 6.625 percent senior notes due 2034 and $1.1 billion aggregate principal amount of 6.875 percent senior notes due 2036 (the Notes). The Company intends to use the proceeds, together with cash on hand, to fund the cash consideration of approximately $3.1 billion for the AliGroup acquisition as well as related fees and expenses. Upon completion of the debt offerings, the Company terminated the remaining outstanding commitments for bridge financing.
Massena East agreement: During the third quarter 2026, Alcoa entered into definitive agreements to sell portions of the Massena East site. The transaction creates the potential for meaningful cash proceeds as approved data center capacity is developed by the buyer. Closing is expected within the next six months. At closing, Alcoa expects to receive approximately $50 million to $65 million, depending on the amount of approved data center capacity. Alcoa may receive an additional approximately $60 million to $250 million for approved capacity expansions and capacity-based installment payments as approved capacity is commissioned during the seven-year period following closing, with most of the proceeds expected to be received during the first five years. Closing is subject to permitting and regulatory approvals, satisfaction of the conditions required to begin construction, and other customary closing conditions.

2026 Outlook

The Company 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, the Company is unable to address the probable significance of the unavailable information, which could be material to future results.

Alcoa reaffirms its 2026 Alumina segment production and shipment projection of 9.5 to 9.6 million metric tons and 11.5 to 11.6 million metric tons, respectively. The difference between production and shipments reflects trading volumes and externally sourced alumina to fulfill customer contracts.

Alcoa reaffirms its 2026 Aluminum segment production and shipment projection of 2.4 to 2.6 million metric tons and 2.6 to 2.8 million metric tons, respectively.

For the fourth quarter 2026, the Company expects to maintain the strong operational performance delivered in the third quarter 2026. Higher production and shipments are expected in both segments, as improved refining system stability is maintained and the smelting portfolio continues to deliver incremental output.

Within the fourth quarter 2026 Alumina Segment Adjusted EBITDA, the Company expects performance to be consistent sequentially.

Within the fourth quarter 2026 Aluminum Segment Adjusted EBITDA, the Company expects higher raw material costs and planned maintenance, intended to support continued operational stability, to result in unfavorable impacts of approximately $30 million sequentially. Alumina costs in the Aluminum segment are expected to be unfavorable by approximately $30 million sequentially.

Other income is expected to increase by approximately $20 million in the fourth quarter 2026 due to higher interest earned on cash held for the AliGroup acquisition.

Alcoa expects Interest expense to approximate $185 million for the year, an increase from the prior projection, as a result of the Notes issuance.

Based on current alumina and aluminum market conditions, Alcoa expects fourth quarter 2026 operational tax expense to approximate $65 million to $75 million, which may vary with market conditions and jurisdictional profitability.

No Offer or Solicitation

This press release is for informational purposes and is not intended to, and shall not, constitute an offer to sell or the solicitation of an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote of approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.

Additional Information and Where to Find It

This press release relates to the Transaction. In connection with the Transaction, Alcoa filed a Registration Statement on Form S-4 on September 1, 2026 (including documents incorporated by reference therein, the Registration Statement), with the SEC. The Registration Statement was declared effective and the related final prospectus was filed on September 8, 2026. This communication is not a substitute for the Registration Statement or any other document that Alcoa may file with the SEC in connection with the Transaction. Before making any investment decision, investors are urged to read the Registration Statement and all relevant documents filed or to be filed with the SEC, as well as any amendments or supplements to those documents, when they become available, because they contain important information about Alcoa and the Transaction.

Investors are able to obtain a free copy of the Registration Statement, as well as other filings containing information about Alcoa, free of charge, at the SEC’s website (www.sec.gov).

Non-GAAP Financial Measures

This press 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). Alcoa 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 and insight on the ability of Alcoa 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 schedules to this release.

The difference between segment totals and consolidated amounts is in Corporate.
⁽¹⁾	Adjusted operating costs include all production related costs for alumina or aluminum produced and shipped: raw materials consumed; conversion costs, such as labor, materials, and utilities; and plant administrative expenses.
⁽²⁾	Other segment items include costs associated with trading activity, the Alumina segment’s purchase of bauxite from offtake or other supply agreements, the Alumina segment’s commercial shipping services, and the Aluminum segment’s energy assets; other direct and non-production related charges, including tariff costs; Selling, general administrative, and other expenses; and Research and development expenses.
⁽³⁾	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. The Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies.
⁽⁴⁾	Transformation includes, among other items, the Adjusted EBITDA of previously closed operations.
⁽⁵⁾	Corporate expenses are composed of general administrative and other expenses of operating the corporate headquarters and other global administrative facilities, as well as research and development expenses of the corporate technical center.
⁽⁶⁾	Other includes certain items that are not included in the Adjusted EBITDA of the reportable segments.

Net income (loss) attributable to Alcoa Corporation common shareholders – as adjusted	$	1.82		$	2.12		$	(0.02	)

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 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 September 30, 2026, a net favorable change in mark-to-market energy derivative instruments ($32); a favorable mark-to-market change on the shares of Ma'aden ($28); external costs related to portfolio actions ($18), primarily related to the AliGroup acquisition; an unfavorable change in foreign exchange derivative instruments ($7); net loss on asset sales ($7); and, a charge for bridge financing structuring fees ($6); for the quarter ended June 30, 2026, an unfavorable mark-to-market change on the shares of Ma'aden ($123); a net unfavorable change in mark to-market energy ($45) and foreign exchange ($14) derivative instruments; external costs related to portfolio actions ($12), primarily related to the AliGroup acquisition; and, net charges for other special items ($2); and, for the quarter ended September 30, 2025, a gain on the sale of interest in the Ma'aden joint venture ($786), a favorable mark-to-market change on the shares of Ma'aden ($267), costs related to the closure of the Kwinana, Australia refinery ($39), a net unfavorable change in mark-to-market energy ($22) and foreign exchange ($12) derivative instruments, costs related to the restart process at the San Ciprián, Spain smelter ($4), external costs related to portfolio actions ($2), and a net benefit for other special items ($1).
⁽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 June 30, 2026, a net charge for discrete tax items ($3); and, for the quarter ended September 30, 2025, a net benefit for discrete tax items ($5).
⁽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 September 30, 2025, undistributed earnings of $3 were allocated to preferred stock under the two-class method.

Adjusted EBITDA, excluding special items	$	789		$	901		$	270

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 September 30, 2026, external costs related to portfolio actions ($18), primarily related to the AliGroup acquisition, and charges for other special items ($1). Additionally, the mark-to-market contracts associated with the Portland, Australia smelter generated losses ($10) in Other (income) expenses, net which economically increase the cost of power recorded in Cost of goods sold and the mark-to-market foreign exchange contracts associated with the San Ciprián refinery and smelter generated gains ($3) in Other (income) expenses, net which economically offset a portion of foreign currency impacts recorded in Cost of goods sold. These non-GAAP reclasses present the total cost of power and net foreign currency impacts within Cost of goods sold.
for the quarter ended June 30, 2026, external costs related to portfolio actions ($12), primarily related to the AliGroup acquisition, total cost of power and net foreign currency impacts associated with the Portland smelter ($5) and San Ciprián refinery and smelter ($5), respectively, and charges for other special items ($2); and,
for the quarter ended September 30, 2025, costs related to the closure of the Kwinana refinery ($39), net cost of power and foreign currency impacts associated with the Portland smelter ($7) and San Ciprián refinery and smelter ($5), respectively, costs related to the restart process at the San Ciprián smelter ($4), external costs related to portfolio actions ($2), and charges for other special items ($2).

Capital expenditures		(171	)		(186	)		(151	)

Free cash flow	$	472		$	422		$	(66	)

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		414		851

Plus: Net pension / OPEB liability		555		613

Adjusted net debt	$	969	$	1,464

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.

Adjusted net debt is also a non-GAAP financial measure. Management believes this measure is 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.
