A. Basis of Presentation– The interim Consolidated Financial Statements of Alcoa Corporation and its subsidiaries (Alcoa Corporation, Alcoa, or the Company) are unaudited. These Consolidated Financial Statements include all adjustments, consisting only of normal recurring adjustments, considered necessary by management to fairly state the Company’s results of operations, financial position, and cash flows. The results reported in these Consolidated Financial Statements are not necessarily indicative of the results that may be expected for the entire year. The 2023 year-end balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (GAAP). This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, which includes disclosures required by GAAP.

In accordance with GAAP, certain situations require management to make estimates based on judgments and assumptions, which may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. They also may affect the reported amounts of revenues and expenses during the reporting periods. Management uses historical experience and all available information to make these estimates. Management regularly evaluates the judgments and assumptions used in its estimates, and results could differ from those estimates upon future events and their effects or new information.

Principles of Consolidation. The Consolidated Financial Statements of Alcoa Corporation include the accounts of Alcoa Corporation and companies in which Alcoa Corporation has a controlling interest, including those that comprise the Alcoa World Alumina & Chemicals (AWAC) joint venture (see below). Intercompany transactions have been eliminated. The equity method of accounting is used for investments in affiliates and other joint ventures over which Alcoa Corporation has significant influence but does not have effective control. Investments in affiliates in which Alcoa Corporation cannot exercise significant influence are accounted for at cost less any impairment, a measurement alternative in accordance with GAAP.

AWAC is an unincorporated global joint venture between Alcoa Corporation and Alumina Limited and consists of several affiliated operating entities, which own, have an interest in, or operate the bauxite mines and alumina refineries within Alcoa Corporation’s Alumina segment (except for the Poços de Caldas mine and refinery and portions of the São Luís refinery, all in Brazil) and a portion (55%) of the Portland smelter (Australia) within Alcoa Corporation’s Aluminum segment. Alcoa Corporation owns 60% and Alumina Limited owns 40% of these individual entities, which are consolidated by the Company for financial reporting purposes and include Alcoa of Australia Limited (AofA), Alcoa World Alumina LLC (AWA), Alcoa World Alumina Brasil Ltda. (AWAB), and Alúmina Española, S.A. (Española). Alumina Limited’s interest in the equity of such entities is reflected as Noncontrolling interest on the accompanying Consolidated Balance Sheet. On August 1, 2024, the Company completed the acquisition of Alumina Limited (see Note C).

B. Recently Adopted and Recently Issued Accounting Guidance

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2023-09 which includes changes to income tax disclosures, including greater disaggregation of information in the rate reconciliation and disclosure of taxes paid by jurisdiction. The guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The adoption of this guidance will provide enhanced disclosures regarding income taxes and will not have a material impact on the Company’s financial statements.

In November 2023, the FASB issued ASU 2023-07 which requires disclosure of significant segment expenses regularly provided to the chief operating decision maker (CODM), other segment items (not included in significant segment expenses for each reportable segment), the title and position of the CODM, and an explanation of how the CODM uses the reported measure of segment profit or loss to assess segment performance and allocate resources. The adoption of this guidance will not have a material impact on the Company’s financial statements and will provide enhanced disclosures regarding reportable segments beginning in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

C. Acquisitions and Divestitures

Alumina Limited Acquisition

On August 1, 2024, Alcoa completed the acquisition of all of the ordinary shares of Alumina Limited (Alumina Shares) through a wholly owned subsidiary, AAC Investments Australia 2 Pty Ltd. Alumina Limited holds a 40% ownership interest in the AWAC joint venture. The acquisition is intended to enhance Alcoa’s position as a leading pure play, upstream aluminum company globally, while simplifying the Company’s corporate structure and governance, resulting in greater operational flexibility and strategic optionality.

Under the Scheme Implementation Deed (the Agreement) entered into in March 2024, as amended in May 2024, holders of Alumina Shares received 0.02854 Alcoa CHESS Depositary Interests (CDIs) for each Alumina Share (the Agreed Ratio), except that i) holders of Alumina Shares represented by American Depositary Shares, each of which represented 4 Alumina Shares, received 0.02854 shares of Alcoa common stock and ii) a certain shareholder received, for certain of their Alumina Shares,0.02854 shares of Alcoa non-voting convertible preferred stock. The Alcoa CDIs are quoted on the Australian Stock Exchange.

At closing, Alumina Shares outstanding of 2,760,056,014 and 141,625,403 were exchanged for 78,772,422 and 4,041,989 shares of Alcoa common stock and Alcoa preferred stock, respectively. Based on Alcoa’s closing share price as of July 26, 2024, the Agreed Ratio implies a value of A$1.45 per Alumina Share and aggregate purchase consideration of approximately $2,800 for Alumina Limited.

The transaction consisted in substance of the acquisition of Alumina Limited’s noncontrolling interest in AWAC, the assumption of Alumina Limited’s indebtedness (approximately $385 as of August 1, 2024, see Note K), and the recognition of deferred tax assets (approximately $100, see Note N) related to Alumina Limited’s prior net operating losses. The increase in ownership in AWAC from 60% to 100%, as well as the assumption of Alumina Limited’s assets and liabilities, will be accounted for as an equity transaction under ASC 810, Consolidation, with the difference in purchase consideration and the net assets acquired recognized as an increase in total Alcoa Corporation shareholders’ equity. The accounting for the transaction is not yet complete and the final value of assets and liabilities acquired is subject to change. Additionally, as of June 30, 2024, the Company recognized transaction costs of $9 in Prepaid expenses and other current assets, which will be reclassified to Additional capital as of August 1, 2024.

Under the terms of the Agreement, Alcoa agreed to provide a shareholder loan to AWAC in place of required capital contributions by Alumina Limited if Alumina Limited’s net debt position exceeded $420 prior to the acquisition closing. Alcoa was not required to and did not provide any shareholder loans to AWAC under this provision.

Warrick Rolling Mill Divestiture

In conjunction with the sale of its rolling mill located at Warrick Operations (Warrick Rolling Mill) in March 2021, the Company recorded estimated liabilities for site separation commitments.

The Company recorded charges of $4 and $15 in thesecond quarter and the six-month period of 2024, respectively, in Other (income) expenses, net on the accompanying Statement of Consolidated Operations related to these commitments. During the second quarter and the six-month period of 2024, the Company spent $5 and $12 against the reserve, respectively.

In the six-month period of 2023, the Company recorded a charge of $17 in Other (income) expenses, net on the accompanying Statement of Consolidated Operations related to these commitments. During the second quarter and six-month period of 2023, the Company spent $11 and $25 against the reserve, respectively.

The remaining balance of $14 at June 30, 2024 is expected to be spent in 2024.

D. Restructuring and Other Charges, Net

In the second quarter and the six-month period of 2024, Alcoa Corporation recorded Restructuring and other charges, net, of $18 and $220, respectively, which were primarily comprised of:

•

A charge of $8 and $205, respectively, for the curtailment of the Kwinana (Australia) refinery; and,

•

A charge of $8 and $12, respectively, for take-or-pay contract costs at the closed Wenatchee (Washington) smelter.

In June 2024, Alcoa completed the full curtailment of the Kwinana refinery, as planned, which was announced in January 2024. As of March 2024, the refinery had approximately 780 employees and this number will be reduced to approximately 250 in the third quarter of 2024 to manage certain processes that will continue until about the third quarter of 2025. At that time, the employee number will be further reduced to approximately 50. In addition to the employees separating as a result of the curtailment, approximately 150 employees will either terminate through the productivity program announced in the third quarter of 2023 or redeploy to other Alcoa operations. Charges related to the curtailment totaled $205 in the six-month period of 2024 and included charges of $129 for water management costs, $41 for severance and employee termination costs for the separation of approximately 580 employees, $15 for asset retirement obligations, $13 for take-or-pay contracts, $5 for asset impairments and $2 for contract terminations. Related cash outlays of approximately $225 (which includes existing employee related liabilities and asset retirement obligations) are expected through 2025, with approximately $145 to be spent in 2024. The Company spent $22 and $24 against the reserve in the second quarter and six-month period of 2024, respectively.

In the second quarter and the six-month period of 2023, Alcoa Corporation recorded Restructuring and other charges, net, of $24 and $173, respectively, which were primarily comprised of:

•

A charge of $101 (six-month period only) for asset impairments and to establish reserves for environmental, demolition and employee severance costs related to the permanent closure of the Intalco (Washington) aluminum smelter;

•

A charge of $47 (six-month period only) for increased reserves for certain employee obligations related to the updated agreement for the San Ciprián (Spain) aluminum smelter; and,

•

A charge of $21 (both periods) related to the settlement of certain pension benefits.

In March 2023, Alcoa Corporation announced the closure of the Intalco aluminum smelter, which had been fully curtailed since 2020. The Company recorded charges of $117 related to the closure, including a charge of $16 in Cost of goods sold on the Statement of Consolidated Operations to write-down remaining inventories to net realizable value and a charge of $101 in Restructuring and other charges, net on the Statement of Consolidated Operations. The restructuring charges were comprised of asset impairments of $50, environmental and demolition obligation reserves of $50, and severance and employee termination costs of $1 for the separation of approximately 12 employees. Cash outlays related to the permanent closure of the site are expected to be $85 over the next three years with approximately $45 to be spent in 2024. The Company spent $9 and $13 against the reserve in the second quarter and six-month period of 2024, respectively.

In February 2023, the Company reached an updated viability agreement with the workers’ representatives of the San Ciprián smelter to commence the restart process in phases beginning in January 2024. The smelter was curtailed in January 2022 as a result of an agreement reached with the workers’ representatives in December 2021. Under the terms of the updated viability agreement, the Company is responsible for certain employee obligations during 2023 through 2025 and made additional commitments for capital improvements of $78. The Company recorded charges of $47 in Restructuring and other charges, net on the Statement of Consolidated Operations to establish the related reserve for employee obligations in the six month period of 2023. Cash outlays related to employee obligations are expected to be $47 through 2025, with approximately $36 to be spent in 2024. The Company spent $9 and $18 against the reserve in the second quarter and six-month period of 2024, respectively. At June 30, 2024, the Company had restricted cash of $86 to be made available for remaining capital improvement commitments at the site of $111 and smelter restart costs of $32 for both the agreement reached with the worker’s representatives in December 2021 and the updated viability agreement in February 2023. Restricted cash is included in Prepaid expenses and other current assets and Other noncurrent assets on the Consolidated Balance Sheet (see Note P).

Alcoa Corporation does not include Restructuring and other charges, net in the results of its reportable segments. The impact of allocating such charges to segment results would have been as follows:

Activity and reserve balances for restructuring charges were as follows:

The activity and reserve balances include only Restructuring and other charges, net that impacted the reserves for Severance and employee termination costs and Other costs. Restructuring and other charges, net that affected other liability accounts such as Accrued pension benefits (see Note L), Asset retirement obligations, and Environmental remediation (see Note O) are excluded from the above activity and balances. Reversals and other includes reversals of previously recorded liabilities and foreign currency translation impacts.

The noncurrent portion of the reserve was $22 and $15 at June 30, 2024 and December 31, 2023, respectively.

E. Segment Information – Alcoa Corporation is a producer of bauxite, alumina, and aluminum products. The Company has two operating and reportable segments: (i) Alumina and (ii) Aluminum. Segment performance under Alcoa Corporation’s management reporting system is evaluated based on a number of factors; however, the primary measure of performance is the Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) for each segment. The Company calculates Segment Adjusted EBITDA as Total sales (third-party and intersegment) minus the following items: Cost of goods sold; Selling, general administrative, and other expenses; and Research and development expenses. Alcoa Corporation’s Segment Adjusted EBITDA may not be comparable to similarly titled measures of other companies. The CODM function regularly reviews the financial information, including Adjusted EBITDA, of these two operating segments to assess performance and allocate resources.

The operating results of Alcoa Corporation’s reportable segments were as follows (differences between segment totals and consolidated amounts are in Corporate):

The following table reconciles Total Segment Adjusted EBITDA to Consolidated net income (loss) attributable to Alcoa Corporation:

(1)

Transformation includes, among other items, the Adjusted EBITDA of previously closed operations.

(2)

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.

(3)

Other includes certain items that are not included in the Adjusted EBITDA of the reportable segments.

The following table details Alcoa Corporation’s Sales by product division:

(1)

Other includes realized gains and losses related to embedded derivative instruments designated as cash flow hedges of forward sales of aluminum.

F. Earnings Per Share – Basic earnings per share (EPS) amounts are computed by dividing earnings by the average number of common shares outstanding. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive share equivalents outstanding.

The share information used to compute basic and diluted EPS attributable to Alcoa Corporation common shareholders was as follows (shares in millions):

In the six-month period of 2024, basic average shares outstanding and diluted average shares outstanding were the same because the effect of potential shares of common stock was anti-dilutive. Had Alcoa generated net income in the six-month period of 2024, two million common share equivalents related tothree million outstanding stock units and stock options combined would have been included in diluted average shares outstanding for the period.

In the second quarter and six-month period of 2023, basic average shares outstanding and diluted average shares outstanding were the same because the effect of potential shares of common stock was anti-dilutive. Had Alcoa generated net income in the second quarter or six-month period of 2023, two million andthree million common share equivalents, respectively, related tothree million outstanding stock units and stock options combined would have been included in diluted average shares outstanding for the periods.

G. Accumulated Other Comprehensive Loss

The following table details the activity of the three components that comprise Accumulated other comprehensive loss for both Alcoa Corporation’s shareholders and Noncontrolling interest:

(1)

These amounts were included in the computation of net periodic benefit cost for pension and other postretirement benefits (see Note L).

(2)

These amounts were reported in Provision for income taxes on the accompanying Statement of Consolidated Operations.

(3)

These amounts were reported in Sales on the accompanying Statement of Consolidated Operations.

(4)

These amounts were reported in Cost of goods sold on the accompanying Statement of Consolidated Operations.

(5)

These amounts were reported in Other (income) expenses, net on the accompanying Statement of Consolidated Operations.

(6)

For the second quarter and six-month period of 2024, these amounts were reported in Sales (both periods) on the accompanying Statement of Consolidated Operations. For the second quarter and six-month period of 2023, $4 was reported in Cost of goods sold (both periods) and $(7) and $(12) were reported in Sales, respectively, on the accompanying Statement of Consolidated Operations.

(7)

A positive amount indicates a corresponding charge to earnings and a negative amount indicates a corresponding benefit to earnings.

H. Investments–A summary of unaudited financial information for Alcoa Corporation’s equity investments is as follows (amounts represent 100% of investee financial information):

The Company’s basis in the ELYSISTM Limited Partnership (ELYSIS) as of June 30, 2024 and 2023, included in Other in the table above, has been reduced tozero for its share of losses incurred to date. As a result, the Company has $66 in unrecognized losses as of June 30, 2024 that will be recognized upon additional contributions into the partnership.

The results for the Saudi Arabia joint venture for the six-month period of 2023 include an adjustment to the estimate for the settlement of a dispute with an industrial utility for periods in 2021 and 2022. Alcoa’s share of this adjustment is $41 which is included in Other (income) expenses, net on the Statement of Consolidated Operations for the six-month period of 2023. Alcoa’s total share of this dispute of $62 includes $21 that was recorded in the fourth quarter of 2022.

I. Receivables

In 2023, a wholly-owned special purpose entity (SPE) of the Company entered into and subsequently amended an agreement with a financial institution to sell up to $130 of certain customer receivables without recourse on a revolving basis. The termination date of the agreement is November 14, 2024. Company subsidiaries sell customer receivables to the SPE, which then transfers the receivables to the financial institution. The Company does not maintain effective control over the transferred receivables, and therefore accounts for the transfers as sales of receivables.

Alcoa Corporation guarantees the performance obligations of the Company subsidiaries, and unsold customer receivables are pledged as collateral to the financial institution to secure the sold receivables. The SPE held unsold customer receivables of $239 and $104 pledged as collateral against the sold receivables as of June 30, 2024 and December 31, 2023, respectively.

The Company continues to service the customer receivables that were transferred to the financial institution. As Alcoa collects customer payments, the SPE transfers additional receivables to the financial institution rather than remitting cash.

In the second quarter of 2024, the Company sold gross customer receivables of $293 and reinvested collections of $293 from previously sold receivables, resulting inno net cash remittance to the financial institution. In thesix-month period of 2024, the Company sold gross customer receivables of $600 and reinvested collections of $584 from previously sold receivables, resulting in net cash proceeds from the financial institution of $16.

In the second quarter of 2023, the Company sold gross customer receivables of $98 and reinvested collections of $104 from previously sold receivables, resulting in a net cash remittance to the financial institution of $6. In thesix-month period of 2023, the Company sold gross customer receivables of $174 and reinvested collections of $127 from previously sold receivables, resulting in net cash proceeds from the financial institution of $47.

Cash collections from previously sold receivables yet to be reinvested of $89 and $99 were included in Accounts payable, trade on the accompanying Consolidated Balance Sheet as of June 30, 2024 and December 31, 2023, respectively. Cash received from sold receivables under the agreement are presented within operating activities in the Statement of Consolidated Cash Flows.

J. Inventories

K. Debt

Short-term Borrowings

Inventory Repurchase Agreements

The Company has entered into inventory repurchase agreements whereby the Company sold aluminum to a third party and agreed to subsequently repurchase substantially similar inventory. The Company did not record sales upon each shipment of inventory and the net cash received of $31 and $56 related to these agreements was recorded in Short-term borrowings within Other current liabilities on the Consolidated Balance Sheet as of June 30, 2024 and December 31, 2023, respectively. The associated inventory sold was reflected in Prepaid expenses and other current assets on the Consolidated Balance Sheet as of June 30, 2024 and December 31, 2023, respectively.

During the second quarter and six-month period of 2024, the Company recorded borrowings of $24 and $45, respectively, and repurchased $45 and $70, respectively, of inventory related to these agreements. During the second quarter and six-month period of 2023, the Company recorded borrowings of $25 (six-month period only) and repurchased $15 (both periods) of inventory related to these agreements.

The cash received and subsequently paid under the inventory repurchase agreements is included in Cash provided from financing activities on the Statement of Consolidated Cash Flows.

144A Debt

2031 Notes

In March 2024, Alcoa Nederland Holding B.V. (ANHBV), a wholly-owned subsidiary of Alcoa Corporation, completed a Rule 144A (U.S. Securities Act of 1933, as amended) debt issuance for $750 aggregate principal amount of 7.125% Senior Notes due 2031 (the 2031 Notes), which carry a green bond designation. The net proceeds of this issuance were $737, reflecting a discount to the initial purchasers of the 2031 Notes as well as issuance costs. The Company is utilizing the net proceeds to finance and/or refinance, in whole or in part, new and/or existing qualifying projects on a two-year look back and three-year look forward that meet certain eligibility criteria within its Green Finance Framework. The net proceeds also support the Company’s cash position and ongoing cash needs, including with respect to its previously announced portfolio actions.

The discount to the initial purchasers, as well as costs to complete the financing, were deferred and are being amortized to interest expense over the term of the 2031 Notes. Interest on the 2031 Notes is paid semi-annually in March and September, and interest payments will commence September 15, 2024. The indenture contains customary affirmative and negative covenants that are similar to those included in the indenture that governs ANHBV’s 4.125% Senior Notes due 2029 issued in March 2021, such as limitations on liens, limitations on sale and leaseback transactions, a prohibition on a reduction in the ownership of AWAC entities below an agreed level, and the calculation of certain financial ratios.

ANHBV has the option to redeem the 2031 Notes on at least 10 days, but not more than 60 days, notice to the holders of the 2031 Notes under multiple scenarios, including, in whole or in part, at any time or from time to time on and after March 15, 2027, at the applicable redemption price specified in the indenture (up to 103.563% of the principal amount plus any accrued and unpaid interest in each case). Also, the 2031 Notes are subject to repurchase upon the occurrence of a change in control repurchase event (as defined in the indenture) at a repurchase price in cash equal to 101% of the aggregate principal amount of the 2031 Notes repurchased, plus any accrued and unpaid interest on the 2031 Notes repurchased.

The 2031 Notes are guaranteed on a senior unsecured basis by the Company and its subsidiaries that are party to the indenture. The 2031 Notes rank equally in right of payment with all of ANHBV’s existing and future senior unsecured indebtedness, including the ANHBV’s senior notes with maturities in 2027, 2028 and 2029; rank senior in right of payment to any future subordinated obligations of ANHBV; and are effectively subordinated to ANHBV’s existing and future secured indebtedness, including under the Revolving Credit Agreement, to the extent of the value of property and assets securing such indebtedness. See Part II Item 8 of Alcoa Corporation’s Annual Report on Form 10-K in Note M to the Consolidated Financial Statements for the year ended December 31, 2023 for more information related to ANHBV’s existing debt and related covenants.

Credit Facilities

Revolving Credit Facility

The Company has a $1,250 revolving credit and letter of credit facility in place for working capital and/or other general corporate purposes (the Revolving Credit Facility). The Revolving Credit Facility, established in September 2016, amended and restated in June 2022 and amended in January 2024, is scheduled to mature in June 2027. Subject to the terms and conditions under the Revolving Credit Facility, the Company or ANHBV, a wholly-owned subsidiary of Alcoa Corporation, may borrow funds or issue letters of credit. Under the terms of the January 2024 amendment, the Company agreed to provide collateral for its obligations under the Revolving Credit Facility. See Part II Item 8 of Alcoa Corporation’s Annual Report on Form 10-K in Note M to the Consolidated Financial Statements for the year ended December 31, 2023 for more information on the Revolving Credit Facility.

There wereno borrowings outstanding at June 30, 2024 and December 31, 2023, andno amounts were borrowed during thesecond quarter and six-month periods of 2024 and 2023 under the Revolving Credit Facility.

Japanese Yen Revolving Credit Facility

The Company entered into a $250 revolving credit facility available to be drawn in Japanese yen (the Japanese Yen Revolving Credit Facility) in April 2023. The Japanese Revolving Credit Facility was amended in January 2024 and in April 2024 (see below) and is scheduled to mature in April 2025. Subject to the terms and conditions under the facility, the Company or ANHBV may borrow funds. The facility includes covenants that are substantially the same as those included in the Revolving Credit Facility. Under the current terms of the January 2024 amendment, the Company agreed to provide collateral for its obligations under the Japanese Yen Revolving Credit Facility. See Part II Item 8 of Alcoa Corporation’s Annual Report on Form 10-K in Note M to the Consolidated Financial Statements for the year ended December 31, 2023 for more information on the Japanese Yen Revolving Credit Facility.

As of June 30, 2024, the Company was in compliance with all financial covenants. The Company may access the entire amount of commitments under the Japanese Revolving Credit Facility. There wereno borrowings outstanding at June 30, 2024 and December 31, 2023. During the second quarter of 2024, no amounts were borrowed. During thesix-month period of 2024, $201 (29,686 JPY) was borrowed and $196 (29,686 JPY) was repaid. No amounts were borrowed during thesecond quarter and six-month period of 2023 under the Japanese Yen Revolving Credit Facility.

On April 26, 2024, the Company entered into an amendment extending the maturity of the Japanese Yen Revolving Credit Facility to April 2025.

Alumina Limited Revolving Credit Facility

In connection with the acquisition of Alumina Limited, the Company assumed approximately $385 of indebtedness as of August 1, 2024, representing the amount drawn on Alumina Limited’s revolving credit facility.

Alumina Limited has a $500 revolving credit facility with tranches maturing in October 2025 ($100), January 2026 ($150), July 2026 ($150), and June 2027 ($100). Alumina Limited’s facility contains a financial covenant limiting the incurrence of indebtedness. As of June 30, 2024, Alumina Limited was in compliance with such covenant and could access the remaining commitments under the facility.

Alumina Limited’s revolving credit facility also contains a clause that allows a majority of lenders, upon a change of control, to issue a notice to Alumina Limited requiring repayment within 90 business days of issuing the notice (the 90-day Notice). Alcoa has engaged with the facility lenders and the lenders have indicated their intention to delay issuing the 90-day Notice until at least December 1, 2024, providing additional time for Alcoa to consider potential repayment or refinancing options subsequent to the acquisition of Alumina Limited.

L. Pension and Other Postretirement Benefits

The components of net periodic benefit cost were as follows:

(1)

These amounts were reported in Other (income) expenses, net on the accompanying Statement of Consolidated Operations (see Note P).

(2)

These amounts were reported in Restructuring and other charges, net on the accompanying Statement of Consolidated Operations and Cash Flows.

Plan Actions. In 2024, management initiated the following actions to a certain pension plan:

Action #1 – On January 8, 2024, Alcoa announced the full curtailment of the Kwinana refinery. As a result, curtailment accounting was triggered within Alcoa’s Australian pension plan. The Company recorded a $1 decrease to Other noncurrent assets and recognized a curtailment loss of $1 ($0 after-tax) in Restructuring and other charges, net on the accompanying Statement of Consolidated Operations.

Action #2 – In the second quarter of 2024, settlement accounting and a related plan remeasurement was triggered within Alcoa’s Australian pension plan as a result of participants electing lump sum payments. Alcoa recorded a $19 increase to Other noncurrent assets and recognized a settlement gain of $1 ($0 after-tax) in Restructuring and other charges, net on the Statement of Consolidated Operations.

(1)

This amount represents the net actuarial loss arising from the curtailment and was recognized immediately in Restructuring and other charges, net on the accompanying Statement of Consolidated Operations.

(2)

This amount represents the net actuarial gain and was reclassified from Accumulated other comprehensive loss to Restructuring and other charges, net on the accompanying Statement of Consolidated Operations.

Funding and Cash Flows. It is Alcoa’s policy to fund amounts for defined benefit pension plans sufficient to meet the minimum requirements set forth in each applicable country’s benefits laws and tax laws, including the Employee Retirement Income Security Act of 1974 (ERISA) for U.S. plans. From time to time, the Company contributes additional amounts as deemed appropriate.

Under ERISA regulations, a plan sponsor that establishes a pre-funding balance by making discretionary contributions to a U.S. defined benefit pension plan may elect to apply all or a portion of this balance toward its minimum required contribution obligations to the related plan in future years.

In the first and second quarters of 2024, management made such elections related to the Company’s U.S. plans and intends to do so for the remainder of 2024. As a result, Alcoa’s minimum required contribution to defined benefit pension plans in 2024 is estimated to be approximately $18, of which approximately $4 was contributed to non-U.S. plans during thesecond quarter of 2024. In the six-month period of 2024, $10 was contributed to non-U.S. plans.

In the second quarter of 2023, $5 was contributed to non-U.S. plans. Insix-month period of 2023, $9 was contributed to non-U.S. plans.

M. Derivatives and Other Financial Instruments

Fair Value

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (ii) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:

•

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

•

Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

•

Level 3 - Inputs that are both significant to the fair value measurement and unobservable.

Derivatives

Alcoa Corporation is exposed to certain risks relating to its ongoing business operations, including the risks of changing commodity prices, foreign currency exchange rates, and interest rates. Alcoa Corporation’s commodity and derivative activities include aluminum, energy, foreign exchange, and interest rate contracts which are held for purposes other than trading. They are used to mitigate uncertainty and volatility, and to cover underlying exposures. While Alcoa does not generally enter into derivative contracts to mitigate the risk associated with changes in aluminum price, the Company may do so in isolated cases to address discrete commercial or operational conditions. Alcoa is not involved in trading activities for energy, weather derivatives, or other nonexchange commodity trading activities.

Alcoa Corporation’s aluminum and foreign exchange contracts are predominantly classified as Level 1 under the fair value hierarchy. All of the Level 1 contracts are designated as either fair value or cash flow hedging instruments. Alcoa Corporation also has several derivative instruments classified as Level 3 under the fair value hierarchy, which are either designated as cash flow hedges or undesignated. Alcoa includes the changes in its equity method investee’s Level 2 derivatives in Accumulated other comprehensive loss in the accompanying Consolidated Balance Sheet.

The following tables present the detail for Level 1 and 3 derivatives (see additional Level 3 information in further tables below):

For the second quarter of 2024, the realized gains and losses on Level 1 cash flow hedges were immaterial. For the second quarter of 2023, the realized gain of $28 on Level 1 cash flow hedges was comprised of a $32 gain recognized in Sales and a $4 loss recognized in Cost of goods sold.

For the six-month period of 2024, the realized gain of $4 on Level 1 cash flow hedges was recognized in Sales. For thesix-month period of 2023, the realized gain of $44 on Level 1 cash flow hedges was comprised of a $48 gain recognized in Sales and a $4 loss recognized in Cost of goods sold.

The following table presents the outstanding quantities of derivative instruments classified as Level 1:

Alcoa Corporation routinely uses Level 1 aluminum derivative instruments to manage exposures to changes in the fair value of firm commitments for the purchases or sales of aluminum. Additionally, Alcoa uses Level 1 aluminum derivative instruments to manage LME exposures at certain locations with profitability improvement actions (expires December 2024), and the Alumar (Brazil) smelter restart (expired December 2023).

Alcoa Corporation uses Level 1 foreign exchange forward contracts to mitigate the risk of foreign exchange exposure related to euro power purchases in Norway (expires December 2026), U.S. dollar aluminum sales in Norway (expires June 2025), U.S. dollar alumina and aluminum sales in Brazil (expires August 2025), and U.S. dollar aluminum sales in Canada (expires March 2025).

Additional Level 3 Disclosures

The following table presents quantitative information related to the significant unobservable inputs described above for Level 3 derivative instruments (megawatt hours in MWh):

The fair values of Level 3 derivative instruments recorded in the accompanying Consolidated Balance Sheet were as follows:

Assuming market rates remain constant with the rates at June 30, 2024, a realized loss of $245 related to power contracts is expected to be recognized in Sales over the next 12 months.

At June 30, 2024 and December 31, 2023, the power contracts with embedded derivatives designated as cash flow hedges include hedges of forecasted aluminum sales of 1,344 kmt and 1,456 kmt, respectively.

The following tables present the reconciliation of activity for Level 3 derivative instruments:

There were no purchases, sales, or settlements of Level 3 derivative instruments in the periods presented.

Other Financial Instruments

The carrying values and fair values of Alcoa Corporation’s other financial instruments were as follows:

The following methods were used to estimate the fair values of other financial instruments:

Cash and cash equivalents and Restricted cash. The carrying amounts approximate fair value because of the short maturity of the instruments. The fair value amounts for Cash and cash equivalents and Restricted cash were classified in Level 1 of the fair value hierarchy.

Short-term borrowings and Long-term debt, including amounts due within one year. The fair value of Long-term debt, less amounts due within one year was based on quoted market prices for public debt and on interest rates that are currently available to Alcoa Corporation for issuance of debt with similar terms and maturities for non-public debt. The fair value amounts for all Short-term borrowings and Long-term debt were classified in Level 2 of the fair value hierarchy.

N. Income Taxes – Alcoa Corporation’s estimated annualized effective tax rate (AETR) for 2024 as of June 30, 2024 differs from the U.S. federal statutory rate of 21% primarily due to losses in certain jurisdictions with full valuation allowances resulting in no tax benefit. In addition, income in foreign jurisdictions with higher statutory tax rates contribute to the variance from 21%.

Alcoa Australia Holdings Pty Ltd (AAH), a wholly-owned indirect subsidiary of Alcoa, made an election prior to July 31, 2024 that results in Alcoa’s other wholly-owned Australian subsidiaries joining AAH’s tax consolidated group (the AAH Tax Consolidated Group). As a result of the acquisition of Alumina Limited, Alumina Limited and all of its Australian subsidiaries, as well as AofA and all of its subsidiaries, joined the AAH Tax Consolidated Group on August 1, 2024. Alcoa will recognize a deferred tax asset of approximately $100 related to the portion of Alumina Limited’s Australian net operating loss carryforwards that the Company has determined are more likely than not to be realized as a result of the consolidated return election.

The Inflation Reduction Act of 2022 (IRA) contains a number of tax credits and other incentives for investments in renewable energy production, carbon capture, and other climate-related actions, as well as the production of critical minerals. In December 2023, the U.S. Treasury issued guidance on Section 45X of the Advanced Manufacturing Tax Credit. The Notice of Proposed Rulemaking (the Notice) clarifies that commercial grade aluminum can qualify for the credit, which was designed to incentivize domestic production of critical materials important for the global transition to renewable energy. In the second quarter and six-month period of 2024, the Company recorded benefits of $10 and $20 in Cost of goods sold, respectively, related to its Massena West smelter (New York) and its Warrick smelter (Indiana). As of June 30, 2024, benefits of $36 were included in Other receivables and $20 were included in Other noncurrent assets on the Consolidated Balance Sheet. As of December 31, 2023, benefits of $36 were included in Other receivables on the Consolidated Balance Sheet.

O. Contingencies

Alcoa Corporation participates in environmental assessments and cleanups at several locations. These include currently or previously owned or operated facilities and adjoining properties, and waste sites, including Superfund (Comprehensive Environmental Response, Compensation and Liability Act (CERCLA)) sites.

Alcoa Corporation’s environmental remediation reserve balance reflects the most probable costs to remediate identified environmental conditions for which costs can be reasonably estimated. The following table details the changes in the carrying value of recorded environmental remediation reserves:

At June 30, 2024 and December 31, 2023, the current portion of the environmental remediation reserve balance was $61 and $66, respectively.

Payments related to remediation expenses applied against the reserve were $10 and $16 in thesecond quarter and six-month period of 2024, respectively. These amounts include mandated expenditures as well as those not required by any regulatory authority or third party.

During the second quarter and six-month period of 2023, the Company incurred liabilities of $4 and $18, respectively. The Company incurred liabilities of $14 for thesix-month period of 2023 primarily related to the closure of the previously curtailed Intalco aluminum smelter, which was recorded in Restructuring and other charges, net (see Note D) on the Statement of Consolidated Operations, and incurred liabilities of $4 for thesecond quarter of 2023 for ongoing remediation work at various other sites, which was recorded in Cost of goods sold on the accompanying Statement of Consolidated Operations. Payments related to remediation expenses applied against the reserve were $16 and $23 in thesecond quarter and six-month period of 2023, respectively. These amounts include mandated expenditures as well as those not required by any regulatory authority or third party. Further, the Company recorded a reversal of a reserve of $1 during thesix-month period of 2023 due to the determination that certain remaining site remediation is no longer required.

The estimated timing of cash outflows from the environmental remediation reserve at June 30, 2024 was as follows:

Reserve balances at June 30, 2024 and December 31, 2023, associated with significant sites with active remediation underway or for future remediation were $199 and $211, respectively. In management’s judgment, the Company’s reserves are sufficient to satisfy the provisions of the respective action plans. Upon changes in facts or circumstances, a change to the reserve may be required. The Company’s significant sites include:

Suriname—The reserve associated with the 2017 closure of the Suralco refinery and bauxite mine is for treatment and disposal of refinery waste and soil remediation. The work began in 2017 and is expected to be completed at the end of 2029.

Hurricane Creek, Arkansas—The reserve associated with the 1990 closure of two mining areas and refineries near Hurricane Creek, Arkansas is for ongoing monitoring and maintenance for water quality surrounding the mine areas and residue disposal areas.

Massena, New York—The reserve associated with the 2015 closure of the Massena East smelter by the Company’s subsidiary, Reynolds Metals Company, is for subsurface soil remediation to be performed after demolition of the structures. Remediation work commenced in 2021 and will take four toeight years to complete.

Point Comfort, Texas—The reserve associated with the 2019 closure of the Point Comfort alumina refinery is for disposal of industrial wastes contained at the site, subsurface remediation, and post-closure monitoring and maintenance. The final remediation plan is currently being developed, which may result in a change to the existing reserve.

Sherwin, Texas—In connection with the 2018 settlement of a dispute related to the previously-owned Sherwin alumina refinery, the Company’s subsidiary, Copano Enterprises LLC, accepted responsibility for the final closure of four bauxite residue waste disposal areas (known as the Copano facility). Work commenced on the first residue disposal area in 2018 and is expected to be completed no later than May 2028. Other than ongoing maintenance and repair activities, work on the next three areas has not commenced but is expected to be completed by 2048, depending on its potential re-use.

Longview, Washington—In connection with a 2018 Consent Decree and Cleanup Action Plan with the State of Washington Department of Ecology, the Company’s subsidiary, Northwest Alloys as landowner, accepted certain responsibilities for future remediation of contaminated soil and sediments at the site located near Longview, Washington. In December 2020, the lessee of the land, who was a partner in the remediation of the site, filed for bankruptcy and exited the site in January 2021. The full site remediation project design, including long-term and post-closure monitoring and maintenance at the site, was approved in March 2023. In the third quarter of 2023, changes in scope and cost increases for remediation resulted in an increase to the reserve. The project is planned to be completed by the end of 2026.

Addy, Washington—The reserve associated with the 2022 closure of the Addy magnesium smelter facility is for site-wide remediation and investigation and post-closure monitoring and maintenance. Remediation work is not expected to begin until 2026 and will take three tofive years to complete. The final remediation plan is currently being developed, which may result in a change to the existing reserve.

Ferndale, Washington—The reserve associated with the 2023 closure of the Intalco aluminum smelter in Ferndale, Washington is for below grade site remediation andfive years of post-closure maintenance and monitoring. The final remediation plan is under review.

Other Sites—The Company isin the process of decommissioning various other plants and remediating sites in several countries for potential redevelopment or to return the land to a natural state. In aggregate, there are remediation projects at 32 other sites that are planned or underway. These activities will be completed at various times in the next three to five years, after which ongoing monitoring and other activities may be required. At June 30, 2024 and December 31, 2023, the reserve balance associated with these activities was $53 and $57, respectively.

Tax

Brazil (AWAB)—Under Brazilian law, taxpayers who generate non-cumulative federal value added tax credits related to exempt exports may either request a refund in cash (monetization) or offset them against other federal taxes owed. In 2012, AWAB requested monetization of $136 (R$273) from the Brazilian Federal Revenue Office (RFB) and received $68 (R$136) that year. In March 2013, AWAB was notified by the RFB that approxi mately $110 (R$220) of value added tax credits previously claimed were being disallowed and a penalty of 50% was assessed. $41 (R$82) of the cash received in 2012 related to the disallowed amount. The value added tax credits were claimed by AWAB for both fixed assets and export sales related to the Juruti bauxite mine and Alumar refinery expansion for tax years 2009 through 2011. The RFB has disallowed credits they allege belong to the consortium in which AWAB owns an interest and should not have been claimed by AWAB. Credits have also been disallowed as a result of challenges to apportionment methods used, questions about the use of the credits, and an alleged lack of documented proof. AWAB presented defense of its claim to the RFB on April 8, 2013.

In February 2022, the RFB notified AWAB that it had inspected the value added tax credits claimed for 2012 and disallowed $4 (R$19). In its decision, the RFB allowed credits of $14 (R$65) that were similar to those previously disallowed for 2009 through 2011. In July 2022, the RFB notified AWAB that it had inspected the value added tax credits claimed for 2013 and disallowed $13 (R$66). In its decision, the RFB allowed credits of $10 (R$53) that were similar to those previously disallowed for 2009 through 2011. AWAB received the 2012 allowed credits with interest of $9 (R$44) in March 2022 and the 2013 allowed credits with interest of $6 (R$31) in August 2022. The decisions on the 2012 and 2013 credits provide positive evidence to support management’s opinion that there is no basis for these credits to be disallowed. AWAB will continue to dispute the credits that were disallowed for 2012 and 2013. If AWAB is successful in this administrative process, the RFB would have no further recourse. If unsuccessful in this process, AWAB has the option to litigate at a judicial level. Separately from AWAB’s administrative appeal, in June 2015, a new tax law was enacted repealing the provisions in the tax code that were the basis for the RFB assessing a 50% penalty in this matter. As such, the estimated range of reasonably possible loss for these matters is $0 to $55 (R$305). It is management’s opinion that the allegations have no basis; however, at this time, the Company is unable to reasonably predict an outcome for this matter.

Australia (AofA)—In December 2019, AofA received a statement of audit position (SOAP) from the Australian Taxation Office (ATO) related to the pricing of certain historic third-party alumina sales. The SOAP proposed adjustments that would result in additional income tax payable by AofA. During 2020, the SOAP was the subject of an independent review process within the ATO. At the conclusion of this process, the ATO determined to continue with the proposed adjustments and issued Notices of Assessment (the Notices) that were received by AofA on July 7, 2020. The Notices asserted claims for income tax payable by AofA of approximately $143 (A$214). The Notices also included claims for compounded interest on the tax amount totaling approximately $474 (A$707).

On September 17, 2020, the ATO issued a position paper with its preliminary view on the imposition of administrative penalties related to the tax assessment issued to AofA. This paper proposed penalties of approximately $86 (A$128).

AofA disagreed with the Notices and with the ATO’s proposed position on penalties. During 2020, AofA lodged formal objections to the Notices, provided a submission on the ATO’s imposition of interest and submitted a response to the ATO’s position paper on penalties. After the ATO completes its review of AofA’s response to the penalties position paper, the ATO could issue a penalty assessment.

To date, AofA has not received a response to its submission on the ATO’s imposition of interest or its response to the ATO’s position paper on penalties.

Through February 1, 2022, AofA did not receive a response from the ATO on AofA’s formal objections to the Notices and, on that date, AofA submitted statutory notices to the ATO requiring the ATO to make decisions on AofA’s objections within a 60-day period. On April 1, 2022, the ATO issued its decision disallowing the Company’s objections related to the income tax assessment, while the position on penalties and interest remains outstanding.

On April 29, 2022, AofA filed proceedings in the Australian Administrative Appeals Tribunal (AAT) against the ATO to contest the Notices. The AAT held the first directions hearing on July 25, 2022 ordering AofA to file its evidence and related materials by November 4, 2022, ATO to file its materials by April 14, 2023 and AofA to file reply materials by May 26, 2023. AofA filed its evidence and related materials on November 4, 2022. The ATO did not file its materials by April 14, 2023. At a directions hearing on May 17, 2023, the ATO was granted an extension to file its materials by August 18, 2023. At a directions hearing on September 26, 2023, the ATO was granted an additional extension to file its materials by November 3, 2023. The ATO filed its materials on November 13, 2023. At a directions hearing on November 22, 2023, AofA was ordered to file any reply materials by March 15, 2024. AofA filed its reply materials on March 15, 2024. The substantive hearing was completed in June 2024, and AofA is awaiting the AAT’s decision.

The Company maintains that the sales subject to the ATO’s review, which were ultimately sold to Aluminium Bahrain B.S.C., were the result of arm’s length transactions by AofA over two decades and were made at arm’s length prices consistent with the prices paid by other third-party alumina customers.

In accordance with the ATO’s dispute resolution practices, AofA paid 50% of the assessed income tax amount exclusive of interest and any penalties, or approximately $74 (A$107), during the third quarter 2020, and the ATO is not expected to seek further payment prior to final resolution of the matter. If AofA is ultimately successful, any amounts paid to the ATO as part of the 50% payment would be refunded. AofA funded the payment with cash on hand and recorded the payment within Other noncurrent assets as a noncurrent prepaid tax asset; at June 30, 2024 the related balance was $72 (A$107).

Further interest on the unpaid tax will continue to accrue during the dispute. The initial interest assessment and the additional interest accrued are deductible against taxable income by AofA but would be taxable as income in the year the dispute is resolved if AofA is ultimately successful. AofA applied this deduction beginning in the third quarter of 2020, reducing cash tax payments. At June 30, 2024 and December 31, 2023, total reductions in cash tax payments were $209 (A$312) and $199 (A$293), respectively, and are reflected within Other noncurrent liabilities and deferred credits as a noncurrent accrued tax liability.

The Company continues to believe it is more likely than not that AofA’s tax position will be sustained and therefore is not recognizing any tax expense in relation to this matter. However, because the ultimate resolution of this matter is uncertain at this time, the Company cannot predict the potential loss or range of loss associated with the outcome, which may materially affect its results of operations and financial condition. References to any assessed U.S. dollar amounts presented in connection with this matter have been converted into U.S. dollars from Australian dollars based on the exchange rate in the respective period.

Legal Proceedings

St. Croix Proceedings—Prior to 2012, Alcoa Inc., the Company’s former parent company, was served with two multi-plaintiff actions alleging personal injury or property damage from Hurricane Georges or winds blowing material from the Company’s former St. Croix alumina facility. These actions were subsequently consolidated into the Red Dust Claims docket in 2017.

In March 2022, the Superior Court of the Virgin Islands issued an amended case management order dividing complaints filed in the Red Dust docket into groups of 50 complaints, designated Groups A through I. The parties selected 10 complaints from Group A to proceed to trial as the Group A lead cases. In May 2024, the Court issued an amended case management order with regard to the Group A lead cases scheduling trials to begin in November 2024. Trials with regard to the Group A lead cases will continue through July 2025. The Court further ordered the parties to participate in mediation on or before August 31, 2024. After completing its case analysis in the second quarter of 2024, the Company recorded a reserve for its estimate of probable loss and a related receivable for insurance proceeds with no material impact to the results of operations.

General

In addition to the matters discussed above, various other lawsuits, claims, and proceedings have been or may be instituted or asserted against Alcoa Corporation, including those pertaining to environmental, safety and health, commercial, tax, product liability, intellectual property infringement, governance, employment, and employee and retiree benefit matters, and other actions and claims arising out of the normal course of business. While the amounts claimed in these other matters may be substantial, the ultimate liability is not readily determinable because of the considerable uncertainties that exist. Accordingly, it is possible that the Company’s liquidity or results of operations in a particular period could be materially affected by one or more of these other matters. However, based on facts currently available, management believes that the disposition of these other matters that are pending or asserted will not have a material adverse effect, individually or in the aggregate, on the financial position of the Company.

Cash and Cash Equivalents and Restricted Cash

Q. Supplier Finance Programs

The Company has various supplier finance programs with third-party financial institutions that are made available to suppliers to facilitate payment term negotiations. Under the terms of these agreements, participating suppliers receive payment in advance of the payment date from third-party financial institutions for qualifying invoices. Alcoa’s obligations to its suppliers, including amounts due and payment terms, are not impacted by its suppliers’ participation in these programs. The Company does not pledge any assets as security or provide any guarantees beyond payment of outstanding invoices at maturity under these arrangements. The Company does not pay fees to the financial institutions under these arrangements. At June 30, 2024 and December 31, 2023, qualifying supplier invoices outstanding under these programs were $123 and $104, respectively, and have payment terms ranging from 50 to 110 days. These obligations are included in Accounts payable, trade on the accompanying Consolidated Balance Sheet.

R. Subsequent Events

On August 1, 2024, the Company completed the acquisition of Alumina Limited (see Note C).

On July 31, 2024, the Board of Directors declared a quarterly cash dividend of $0.10 per share of the Company’s common stock and Series A convertible preferred stock, to be paid on August 29, 2024 to stockholders of record as of the close of business on August 12, 2024. Dividends on Alcoa’s common and preferred shares are paid in U.S. dollars. Dividends on CDIs paid in a currency other than U.S. dollar will be determined using foreign currency exchange rates as of August 22, 2024.

In May 2022, the Company received a Notice of Violation (NOV) from the U.S. Environmental Protection Agency (the EPA). The NOV alleges violations under the Clean Air Act at the Company’s Intalco smelter from when the smelter was operational. The EPA referred the matter to the U.S. Department of Justice, Environment and Natural Resources Division (the DOJ) in May 2022. The DOJ and the Company agreed to a stipulated settlement, which was filed with the United States District Court for the Western District of Washington at Seattle on July 18, 2024, requiring the Company to pay a civil fine of $5. An accrual for this matter was included within Other current liabilities on the Consolidated Balance Sheet as of June 30, 2024.
