Notes to the Consolidated Financial Statements (unaudited)

(dollars in millions, except per-share and per metric ton amounts)

A. Basis of Presentation and Proposed Merger

The interim Consolidated Financial Statements of Arconic Corporation and its subsidiaries (“Arconic” 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 2022 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 Form 10-Q report should be read in conjunction with Arconic’s Annual Report on Form 10-K for the year ended December 31, 2022, which includes all 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. Actual results could differ from those estimates upon subsequent resolution of identified matters.

References in these Notes to “ParentCo” refer to Arconic Inc., a Delaware corporation, and its consolidated subsidiaries (through March 31, 2020, at which time it was renamed Howmet Aerospace Inc. (“Howmet”)). On April 1, 2020 (the “Separation Date”), ParentCo separated into two standalone, publicly-traded companies, Arconic Corporation and Howmet (the “Separation”). In connection with the Separation, as of March 31, 2020, the Company and Howmet entered into several agreements to effect the Separation, including a Separation and Distribution Agreement and a Tax Matters Agreement. See Note A to the Consolidated Financial Statements in Part II Item 8 of Arconic Corporation’s Annual Report on Form 10-K for the year ended December 31, 2022 for additional information. Also, references in these Notes to “2016 Separation Transaction” refer to the November 1, 2016 separation of Alcoa Inc., a Pennsylvania corporation, into two standalone, publicly-traded companies, Arconic Inc. and Alcoa Corporation.

Proposed Merger. On May 4, 2023, Arconic entered into an Agreement and Plan of Merger (the “Merger Agreement”) to be acquired by funds managed by affiliates of Apollo Global Management, Inc., along with a minority investment from funds managed by affiliates of Irenic Capital Management LP, in an all-cash transaction that values Arconic at an enterprise value of approximately $5,000 (the “Transaction”). On the terms and subject to the conditions of the Merger Agreement, the Company’s stockholders will receive $30.00 per share in cash in exchange for each share of outstanding common stock. The Transaction is expected to close in the third quarter of 2023, subject to customary closing conditions, including approval by the Company’s stockholders. The Merger Agreement was adopted by the Company’s stockholders at a special meeting of the Company’s stockholders on July 25, 2023. Upon the closing of the Transaction, Arconic will operate as a privately-held company. In the 2023 second quarter, Arconic recognized $11 in Restructuring and other charges (see Note E) on the accompanying Statement of Consolidated Operations for incurred fees and expenses associated with the Transaction. Additional merger-related costs are expected to be recognized in a future period; however, such amounts are contingent on the outcome of the Transaction. Assuming the Transaction closes, the Company expects to recognize approximately $60 of additional acquisition-related expenses, which have not been accrued to date, associated with contractual agreements that are contingent upon the closing of the Transaction.

B. Recently Adopted and Recently Issued Accounting Guidance

Adopted

On January 1, 2023, Arconic adopted changes issued by the Financial Accounting Standards Board (FASB) to the disclosure of supplier finance programs. The FASB issued this guidance to address a perceived lack of transparency about such programs, which may prevent an understanding by financial statement users of the effect these programs have on an entity’s working capital, liquidity, and cash flows. Supplier finance programs (also may be referred to as reverse factoring, payables finance, or structured payables arrangements) allow a buyer to offer its suppliers the option for access to payment in advance of an invoice due date, which is paid by a third-party finance provider or intermediary on the basis of invoices that the buyer has confirmed as valid. Generally, a buyer (i) enters into an agreement with a finance provider or an intermediary to establish the program, (ii) purchases goods and services from suppliers with a promise to pay at a later date, and (iii) notifies the finance provider or intermediary of the supplier invoices that it has confirmed as valid. The suppliers may then request early payment directly from the finance provider or intermediary for those confirmed invoices. In the fiscal year of adoption, the guidance requires a buyer in a supplier finance program to disclose the following information in all reporting periods: (i) the key terms of the program, including a description of the payment terms and any assets pledged as security or other forms of guarantees provided for the committed payment to the finance provider or intermediary, and (ii) for the obligations that the buyer has confirmed as valid to the finance provider or intermediary, the amount outstanding that remains unpaid by the buyer as of the end of the reporting period and a description of where those obligations are presented in the balance sheet. In subsequent years, only the amount of obligations outstanding that the buyer has confirmed as valid to the finance provider or intermediary as of the end of the reporting period is required disclosure for interim periods while all the previously mentioned information is required disclosure for annual periods, including an incremental requirement to present a roll forward of the obligations, including the amount of obligations confirmed and the amount of obligations subsequently paid. The Company has an existing arrangement with a financial institution to make available this type of program to its suppliers. Other than disclosing the required information (see Note R), the adoption of this guidance did not have an impact on the Consolidated Financial Statements.

Issued

In March 2020, the FASB issued guidance that provides optional expedients and exceptions for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. These expedients and exceptions may be used when applying GAAP, if certain criteria are met, to contracts, hedging relationships, and other transactions that reference London Inter-Bank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of such reform. The purpose of this guidance is to provide relief to entities from experiencing unintended accounting and/or financial reporting outcomes or consequences due to reference rate reform. This guidance became effective immediately on March 12, 2020 and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022, after which time the expedients and exceptions expire (see below). In January 2021, the FASB issued clarifying guidance to specify that certain of the optional expedients and exceptions apply to derivatives that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. This additional guidance may be applied on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively in the manner previously described for the guidance issued on March 12, 2020. In December 2022, the FASB extended the expiration of the optional expedients and exceptions to December 31, 2024. Through ~~March~~June 3130, 2023, Arconic has not experienced any unintended outcomes or consequences of reference rate reform that would necessitate the adoption of this guidance. Additionally, the Company’s credit agreement, which previously provided a credit facility that was referenced to LIBOR in certain borrowing situations, was amended in February 2022 to replace LIBOR with the Secured Overnight Financing Rate (SOFR) (see Note N). Management will continue to closely monitor all potential instances of reference rate reform to determine if adoption of this guidance becomes necessary in the future.

D. Segment and Related Information

Arconic’s profit or loss measure for its reportable segments is Segment Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization). The Company calculates Segment Adjusted EBITDA as Total sales (third-party and intersegment) minus each of (i) Cost of goods sold, (ii) Selling, general administrative, and other expenses, and (iii) Research and development expenses, plus each of (i) Stock-based compensation expense, (ii) Metal price lag, and (iii) Unrealized (gains) losses on mark-to-market hedging instruments and derivatives. Arconic’s Segment Adjusted EBITDA may not be comparable to similarly titled measures of other companies’ reportable segments.

The operating results of Arconic’s reportable segments were as follows (differences between segment totals and the Company’s consolidated totals for line items not reconciled are in Corporate):

(1)Corporate expenses are composed of general administrative and other expenses of operating the corporate headquarters and other global administrative facilities.

(2)Metal price lag represents the financial impact of the timing difference between when aluminum prices included in Sales are recognized and when aluminum purchase prices included in Cost of goods sold are realized. This adjustment aims to remove the effect of the volatility in metal prices and the calculation of this impact considers applicable metal hedging transactions.

(4)Other includes certain items that impact Cost of goods sold and Selling, general administrative, and other expenses on the Company’s Statement of Consolidated Operations that are not included in Segment Adjusted EBITDA. In the 2022 second quarter and six-month period, the respective amounts include costs related to a new union labor agreement of $19 (see Note G) and environmental remediation charges of $9, both of which were recorded in Cost of goods sold on the accompanying Statement of Consolidated Operations.

E. Restructuring and Other Charges

In the ~~2022~~2023 ~~first~~second quarter and six-month period, Arconic recorded Restructuring and other charges of $5,9 which were comprised of the following components: aan $411 charge ~~related to several legacy non-U.S. matters, including $1~~ for ancosts ~~environmental~~incurred ~~remediation obligation~~ related to ~~Italy and $1 for~~ the ~~full~~Transaction ~~settlement of certain employee retirement benefits related to Brazil~~ (see Note GA); and a $12 ~~charge~~net ~~related~~credit tofor ~~idling~~other ~~certain operations in the Extrusions segment (actions initiated in 2021)~~items.

In the 2022 second quarter and six-month period, Arconic recorded Restructuring and other charges of $2 and $7, respectively, which were comprised of the following components: a $1 and $5, respectively, charge related to several legacy non-U.S. matters, including $1 (six-month period) for an environmental remediation obligation related to Italy and $1 (six-month period) for the full settlement of certain employee retirement benefits related to Brazil (see Note G); and a $1 and $2, respectively, charge related to idling certain operations in the Extrusions segment (actions initiated in 2021).

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

In the 2022 second quarter and six-month period, Foreign currency gains, net includes a $54 gain for the remeasurement of monetary balances, primarily cash, related to the Company’s former operations in Russia from rubles to U.S. dollar. This gain was the result of a significant strengthening of the ruble against the U.S. dollar in the 2022 second quarter.

* Service cost was reported in Cost of goods sold, Settlements were reported in Restructuring and other charges, and all other components were reported in Other expenses, net on the accompanying Statement of Consolidated Operations.

United Steelworkers Labor Agreement—On May 14, 2022, the Company and the United Steelworkers reached a tentative four-year labor agreement covering approximately 3,300 employees at four U.S. locations; the previous labor agreement expired on May 15, 2022. The tentative agreement was ratified by the union employees on June 1, 2022. In the 2022 second quarter and six-month period, Arconic recognized $19 in Cost of goods sold on the accompanying Statement of Consolidated Operations primarily for a one-time signing bonus for the covered employees. Additionally, the new labor agreement provides for, among other items, established annual wage increases and higher multipliers used to calculate the union employees’ future pension retirement benefits.

The change to the pension benefits qualifies as a significant plan amendment to the Company’s U.S. hourly defined benefit pension plan, and, as a result, Arconic was required to complete a remeasurement of this plan (generally completed as of December 31st each year), including an interim actuarial valuation of the plan obligations. Communication of the benefit change to the union employees occurred on May 15, 2022, and the effective date of this amendment was May 16, 2022. For purposes of performing an interim remeasurement of the plan, the Company applied a practical expedient to the remeasurement date and selected May 31, 2022. Accordingly, the discount rate used in calculating the plan obligations increased to 4.66% at May 31, 2022 from 2.96% at December 31, 2021. The remeasurement of this plan, together with the amendment for increased benefits, resulted in a $13 net decrease to Accrued pension benefits and a $10 (after-tax) net decrease to Accumulated other comprehensive loss (see Note K). Additionally, annual net periodic benefit cost to be recognized for this plan in 2022 increased by $8, comprised of a $2 decrease in service cost and a $10 increase in non-service costs. These amounts were recognized ratably over the remainder of 2022 (June through December).

H. Income Taxes

Arconic’s year-to-date tax provision is comprised of the most recent estimated annual effective tax rate applied to year-to-date pretax ordinary income or loss. The tax impacts of unusual or infrequently occurring items, including changes in judgment about the realizability of deferred tax assets in future years and effects of changes in tax laws or rates, are recorded discretely in the interim period in which they occur. In addition, the tax provision is adjusted for the interim period impact of non-benefited pretax losses.

For the 2023 ~~first~~six-month ~~quarter~~period, the estimated annual effective tax rate, before discrete items, applied to ordinary income was 2827.60%. This rate differs by 7.6.0 percentage points from the U.S. federal statutory rate of 21.0% primarily due to the state tax impact of domestic taxable income, U.S. tax on foreign earnings, and non-deductible costs, ~~and foreign losses benefited in lower rate jurisdictions,~~ partially offset by a valuation allowance release for a capital loss carryforward and non-taxable income. In the 2023 ~~first~~six-month ~~quarter~~period, Arconic realized capital gain income supporting the utilization of the capital loss carryforward.

For the 2022 ~~first~~six-month ~~quarter~~period, the estimated annual effective tax rate, before discrete items, applied to ordinary ~~loss~~income was 2725.86%. This rate differs by 64.86 percentage points from the U.S. federal statutory rate of 21.0% primarily due to estimated U.S. tax on global intangible low-taxed income, ~~non-deductible costs,~~ the state tax impact of domestic taxable income, ~~foreign losses in jurisdictions subject to existing valuation allowances,~~ and U.S. tax on foreign earnings, partially offset by non-taxable income and foreign income taxed in lower rate jurisdictions.

The effective tax rate including discrete items was 2822.64% and 24.3% in the 2023 ~~first~~second quarter and 22six-month period, respectively, and 24.8% and 24.2% in the 2022 ~~first~~second quarter and six-month period, respectively.

The following table presents the components of Provision for income taxes:

I. Earnings Per Share

Basic earnings per share (EPS) amounts are computed by dividing Net income attributable to Arconic by the weighted-average number of common shares outstanding. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive share equivalents outstanding. Specific to Arconic, such share equivalents consist of outstanding employee stock awards (excluding out-of-the-money stock options – see below). For periods in which the Company generates net income, the diluted weighted-average number of shares include common share equivalents associated with outstanding employee stock awards. For periods in which the Company generates a net loss, common share equivalents are excluded from the diluted weighted-average number of shares as their effect is anti-dilutive.

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

First quarter ended March 31,	2023	2022
	Second quarter ended June 30,		Six months ended June 30,
Weighted-average shares outstanding – basic	99.4	105.4

_____________________

* Stock options are in-the-money when the respective exercise price of each such option is less than the average market price of the Company’s common stock during the applicable period presented. Conversely, stock options are out-of-the-money when the respective exercise price of each such option is more than the average market price of the Company’s common stock during the applicable period presented. Out-of-the-money stock options never result in common share equivalents for purposes of diluted EPS regardless of whether a company generates net income or a net loss. As of ~~March~~June 3130, 2023 and ~~March~~June 3130, 2022, there were 0.21 million and 0.3 million, respectively, out-of-the-money stock options outstanding with a weighted-average exercise price of $3132.1973 and $31.48, respectively.

J. Preferred and Common Stock

On November 16, 2022, Arconic announced that its Board of Directors approved a share repurchase program authorizing the Company to repurchase shares of its outstanding common stock up to an aggregate transactional value of $200 over a two-year period expiring November 17, 2024. Repurchases under the program may be made from time to time, as the Company deems appropriate, based on a variety of factors such as price, capital position, liquidity, financial performance, alternative uses of capital, and overall market conditions. There can be no assurance as to the number of shares the Company will purchase. The share repurchase program may be increased or otherwise modified, renewed, suspended, or terminated by the Company at any time, without prior notice. This program is intended to comply with Rule 10b5-1 and all purchases shall be made in compliance with Rule 10b-18, including without limitation, the timing, price, and volume restrictions thereof. In the 2023 ~~first~~six-month ~~quarter~~period, Arconic repurchased 35,615 shares of the Company’s common stock for $1 under this program. Cumulatively, Arconic has repurchased 2,107,450 shares of the Company’s common stock for $47 since the program’s inception.

On May 4, 2021, Arconic announced that its Board of Directors approved a share repurchase program authorizing the Company to repurchase shares of its outstanding common stock up to an aggregate transactional value of $300 over a two-year period expiring April 28, 2023. In the 2022 ~~first~~second quarter and six-month period, Arconic repurchased ~~505~~1,~~982~~324,027 and 1,830,009 shares, respectively, of the Company's common stock for $1637 and $53, respectively, under this program. Cumulatively, Arconic repurchased 9,776,177 shares of the Company’s common stock for $300 since the program’s inception, resulting in completion of the total authorization under this program in August 2022. In connection with the establishment of the new repurchase program (see above), this repurchase program was terminated. Repurchases under the program were made from time to time, as the Company deemed appropriate, solely through open market repurchases effected through a broker dealer, based on a variety of factors such as price, capital position, liquidity, financial performance, alternative uses of capital, and overall market conditions. This program was intended to comply with Rule 10b5-1 and all purchases were made in compliance with Rule 10b-18, including without limitation the timing, price, and volume restrictions thereof.

N. Debt

Arconic maintains a five-year credit agreement, dated May 13, 2020, with a syndicate of lenders named therein and Deutsche Bank AG New York Branch as administrative agent (the “ABL Credit Agreement”). The ABL Credit Agreement provides for a $1,200 senior secured asset-based revolving credit facility (the “ABL Credit Facility”) to be used, generally, for working capital or other general corporate purposes. See Note Q to the Consolidated Financial Statements in Part II Item 8 of Arconic’s Annual Report on Form 10-K for the year ended December 31, 2022 (filed on February 21, 2023) for additional information related to the ABL Credit Agreement.

In the 2023 ~~first~~six-month ~~quarter~~period, the Company borrowed $~~150~~175 and repaid $~~100~~175 under the ABL Credit Facility. These borrowings were designated as SOFR loans with an initial one-month interest period. ~~Arconic may repay early or extend a part or all of these borrowings.~~ In the 2023 ~~first~~second quarter and six-month period, the weighted-average interest rate and weighted-average days outstanding of the borrowings was 6.580% and 306.61%, respectively, and 36 days and 55 days, respectively. In March 2022, the Company borrowed $100 under the ABL Credit Facility. This borrowing was designated as a SOFR loan with an initial three-month interest period. AsIn ofJune ~~March 31,~~ 2022, the Company extended this borrowing for an additional three-month period. The applicable rate on this borrowing was 2.50% through June 15, 2022 and 4. 22% beginning June 16, 2022. On June 30, 2022, Arconic repaid early $50 of this borrowing.

Availability under the ABL Credit Facility is subject to a monthly borrowing base calculation, which, in general, is determined by applying a predetermined percentage to the amount of eligible accounts receivable and inventory, less customary reserves. As of ~~March~~June 3130, 2023, the available balance was $1,~~134~~189 (net of outstanding ~~borrowings of $50 and~~ letters of credit of $1611).

O. Acquisitions and Divestitures

Russia. On November 15, 2022, Arconic completed the sale of all of its operations in Russia to Promishlennie Investitsii LLC, the majority owner of VSMPO-AVISMA Corporation. The legal form of the transaction was a stock sale of all the Company’s Russian subsidiaries. At that time, VSMPO-AVISMA owned a limited portion of one of these legal entities, which was reported as Noncontrolling interest in the accompanying Consolidated Financial Statements prior to consummation of the sale transaction. See Note S to the Consolidated Financial Statements in Part II Item 8 of Arconic’s Annual Report on Form 10-K for the year ended December 31, 2022 (filed on February 21, 2023) for additional information related to this transaction.

Arconic’s former operations in Russia were comprised of one principal location in Samara, which manufactured sheet, plate, extrusions, and forgings across all of the Company’s end markets. Prior to the sale transaction, the operating results of Arconic’s former operations in Russia were reported in the Company’s Rolled Products segment. The following table presents selected financial information related to Arconic’s former operations in Russia:

First quarter ended March 31,	2022
	Second quarter ended June 30, 2022		Six months ended June 30, 2022
Third-party sales*	~~233~~$	314	$	547
Segment Adjusted EBITDA	1824		42

_____________________

*Third-party sales include aluminum products manufactured at the Company’s former plant in Russia and sold through Arconic’s international selling company located in Hungary.

Building and Construction Systems. On June 6, 2022, the Company announced that it was evaluating strategic options for the businesses that comprise the Building and Constructions Systems segment, including exploring a sale of its architectural systems business (Kawneer® brand). Subsequent to this announcement, Arconic initiated a sale process with respect to its architectural systems business, which has six principal locations in the United States, Canada, and Europe. Products manufactured under the Kawneer brand include windows, doors, and curtain walls. This business generated third-party sales of approximately $970 in 2022 and had approximately 2,~~800~~900 employees as of ~~March~~June 3130, 2023.

On August 2, 2022, the Company announced a pause in the sale process of this business due to unfavorable economic conditions, particularly uncertainty in the debt markets. This business will remain classified as held and in-use in Arconic’s Consolidated Financial Statements and will continue to be reported within the Building and Construction Systems segment.

P. Contingencies and Commitments

Unless specifically described to the contrary, all matters within Note P are the full responsibility of Arconic pursuant to the Separation and Distribution Agreement. Additionally, the Separation and Distribution Agreement provides for cross-indemnities between the Company and Howmet for claims subject to indemnification.

Contingencies

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

A liability is recorded for environmental remediation when a cleanup program becomes probable and the costs can be reasonably estimated. As assessments and cleanups proceed, the liability is adjusted based on progress made in determining the extent of remedial actions and related costs. The liability can change substantially due to factors such as, among others, the nature and extent of contamination, changes in remedial requirements, and technological changes.

The Company’s remediation reserve balance was $7672 and $85 (of which $3634 and $40, respectively, was classified as a current liability) at ~~March~~June 3130, 2023 and December 31, 2022, respectively, and reflects the most probable costs to remediate identified environmental conditions for which costs can be reasonably estimated.

In the 2023 ~~first~~six-month ~~quarter~~period, the ~~Company~~remediation ~~recorded~~reserve awas ~~charge~~increased ofby $1 due to a charge (recorded in Cost of goods sold) ~~and increased the remediation reserve by the same amount~~ related to the estimated costs of future operations, maintenance, and monitoring activities at several sites.

Payments related to remediation expenses applied against the reserve were $104 and $14, respectively, in the 2023 ~~first~~second quarter and six-month period, which include expenditures currently mandated, as well as those not required by any regulatory authority or third party.

The Separation and Distribution Agreement includes provisions for the assignment or allocation of environmental liabilities between Arconic and Howmet, including certain remediation obligations associated with environmental matters. In general, the respective parties are responsible for the environmental matters associated with their operations, and with the properties and other assets assigned to each. Additionally, the Separation and Distribution Agreement lists environmental matters with a shared responsibility between the two companies with an allocation of responsibility and the lead party responsible for management of each matter. For matters assigned to Arconic and Howmet under the Separation and Distribution Agreement, the companies have agreed to indemnify each other in whole or in part for environmental liabilities arising from operations prior to the Separation Date.

The following description provides details regarding the Company's largest reserve (next largest is $6), which relates to one of Arconic's current operating locations.

Massena, NY—Arconic has an ongoing remediation project related to the Grasse River, which is adjacent to the Company’s Massena plant site. Many years ago, it was determined that sediments and fish in the river contain varying levels of polychlorinated biphenyls (PCBs). The project, which was selected by the U.S. Environmental Protection Agency (EPA) in a Record of Decision issued in April 2013, was aimed at capping PCB contaminated sediments with concentration in excess of one part per million in the main channel of the river and dredging PCB contaminated sediments in the near-shore areas where total PCBs exceed one part per million. The EPA approved the final design phase of the project in March 2019. Following the EPA’s approval, the actual remediation fieldwork commenced. In April 2020, the EPA approved an addendum to the final remedial design to address newly-identified matters, including river navigation issues, which resulted in changing the original remedy for a specific segment of the river to dredging from capping. The Company attained substantial completion of remedial construction activities on the Grasse River in September 2021.

In March 2022, an ice jam event occurred in a section of the river where the cap was installed. The ice accumulation caused a blockage in the river that restricted flow, which resulted in high forces being placed on the bottom sediments as the river worked its way through the obstruction. Once the ice cleared and it was safe to enter the river, Arconic investigated and analyzed the cap for any damage. It was determined that portions of the cap were damaged and there was disturbance to the underlying sediments. As a result, over the next several months, the Company performed extensive environmental, geotechnical, and ice modeling investigations to support the preparation of a proposed plan to repair the damaged cap and contain the exposed sediment. These activities were completed in September 2022 and led to a completed design and estimated cost of $22 for the proposed repair remedy, which included consideration of a temporary work stoppage due to the winter

2223

season extending the repair work into 2023 and the impact of cost inflation for labor and materials. Arconic’s existing reserve included consideration of potential future cap repairs given the magnitude and nature of the previously completed remediation project. As a result, in 2022, the Company increased the reserve balance for this matter by $13 for the incremental amount needed to cover the estimated cost of the proposed plan. On October 3, 2022, Arconic submitted an Analysis of Alternatives report to the EPA setting forth four potential remedies, including the Company’s proposed plan. On December 22, 2022, at the EPA’s request, Arconic submitted a revised Analysis of Alternatives report to address two additional repair remedies for a total of six potential alternatives. Arconic is now waiting on the EPA’s response, but continues to maintain an active dialogue with the EPA, as well as other stakeholders, all in support of the EPA making a final decision, which the Company expects in the near term. Arconic’s proposed remedy is consistent with the Record of Decision issued for the original remediation project (see above). In advance of the EPA’s decision, the Company performed a portion of the work associated with its proposed remedy in order to reduce the environmental risk associated with the exposed sediments. This work was completed by the end of November 2022.

As the project progresses, further changes to the reserve may be required due to factors such as, among others, the EPA’s selection of a remedy that differs from Arconic’s proposed plan, additional changes in other remedial requirements, increased site restoration costs, and incremental ongoing operation and maintenance costs.

At ~~March~~June 3130, 2023 and December 31, 2022, the reserve balance associated with this matter was $3130 and $38, respectively. Timing of expenditures is contingent on the EPA’s decision with respect to the repair remedy and the subsequent mobilization of third-party contractors.

Litigation.

All references to ParentCo in the matters described under this section Litigation refer to Arconic Inc. only and do not include its subsidiaries, except as otherwise stated.

Reynobond PE—On June 13, 2017, the Grenfell Tower in London, U.K. caught fire resulting in fatalities, injuries, and damage. A French subsidiary of Arconic Corporation (of ParentCo at that time), Arconic Architectural Products SAS (AAP SAS), supplied a product, Reynobond PE, to its customer, a cladding system fabricator, which used the product as one component of the overall cladding system on Grenfell Tower. The fabricator supplied its portion of the cladding system to the facade installer, who then completed and installed the system under the direction of the general contractor. Neither ParentCo nor AAP SAS was involved in the design or installation of the system used at the Grenfell Tower, nor did it have a role in any other aspect of the building’s refurbishment or original design. Regulatory investigations into the overall Grenfell Tower matter are being conducted, including a criminal investigation by the London Metropolitan Police Service (the “Police”), a Public Inquiry by the British government, and a consumer protection inquiry by a French public authority. The Public Inquiry was announced by the U.K. Prime Minister on June 15, 2017 and subsequently was authorized to examine the circumstances leading up to and surrounding the Grenfell Tower fire in order to make findings of fact and recommendations to the U.K. Government on matters such as the design, construction, and modification of the building, the role of relevant public authorities and contractors, the implications of the fire for the adequacy and enforcement of relevant regulations, arrangements in place for handling emergencies, and the handling of concerns from residents, among other things. Hearings for Phase 1 of the Public Inquiry began on May 21, 2018 and concluded on December 12, 2018. Phase 2 hearings of the Public Inquiry began in early 2020 and concluded in 2022, following which a final report will be written and subsequently published. As Phase 2 of the public inquiry concluded, the testimony supported AAP SAS’s position that the choice of materials and the responsibility of ensuring compliance of the cladding system with relevant U.K. building code and regulations was with those individuals or entities who designed and installed the cladding system such as the architects, fabricators, contractors and building owners. The ongoing hearings in the U.K. have revealed serious doubts about whether these third parties had the necessary qualifications or expertise to carry out the refurbishment work at Grenfell Tower, adequately oversaw the process, conducted the required fire safety testing or analysis, or otherwise complied with their obligations under U.K. regulations. AAP SAS is participating as a Core Participant in the Public Inquiry and is also cooperating with the ongoing parallel investigation by the Police. Arconic Corporation does not sell and ParentCo previously stopped selling the PE product for architectural use on buildings. Given the preliminary nature of these investigations and the uncertainty of potential future litigation, Arconic Corporation cannot reasonably estimate at this time the likelihood of an unfavorable outcome or the possible loss or range of losses in the event of an unfavorable outcome.

United Kingdom Litigation.

Claims brought by Survivors and Estates of Decedents

Beginning in 2020, multiple claimant groups comprised of survivors and estates of decedents of the Grenfell Tower fire comprised of approximately 1,000 claimants filed claims in the U.K. arising from that fire against numerous defendants including AAP SAS, Arconic Corporation, Howmet Aerospace Inc., and other defendants. These claims were consolidated and stayed by the Court in order for the claimants and defendants to discuss alternate dispute resolution. The substantial majority of these suits were settled in the first quarter of 2023 pursuant to the terms of a confidential settlement agreement and are now discontinued and closed. Those suits that have not settled are the subject of ongoing alternate dispute resolution discussions though there is no certainty that such discussions will result in any settlement. The suits that remain are stayed until the next case management conference, which was postponed until a to-be-determined date in either October or November 2023 (previously scheduled for June 27, 2023). At December 31, 2022, based on a potential settlement of these suits, Arconic recorded a reserve of $61 for its share of a settlement and a related receivable of $53 for costs to be covered by insurance proceeds. The reserve was reported in Other current liabilities and the receivable was reported in Prepaid expenses and other current assets on the accompanying Consolidated Balance Sheet. In the 2023 first quarter, the Company paid $43 for legal settlements applied against the reserve and received insurance proceeds of $41. Also, in July 2023, the Company paid an additional $8 against the previously established reserve.

The reserve was reported in Other current liabilities and the receivable was reported in Prepaid expenses and other current assets on the accompanying Consolidated Balance Sheet. In the 2023 first quarter, the Company paid $43 for legal settlements applied against the reserve and received insurance proceeds of $41.

Claims brought by Emergency Responders

Beginning in 2020, multiple claimant groups comprised of emergency responders who attended the Grenfell Tower fire comprised of approximately 150 claimants filed claims against AAP SAS and other defendants in the London High Court arising out of the fire. These claims were consolidated and stayed by the Court in order for the claimants and defendants to discuss alternate dispute resolution. Those alternate dispute resolutions discussions are ongoing though there is no certainty that such discussions will result in any settlement. Given the preliminary nature of these matters and the uncertainty of litigation, Arconic cannot reasonably estimate at this time the likelihood of an unfavorable outcome or the possible loss or range of losses in the event of an unfavorable outcome in the above-referenced disputes. The suits remain stayed until the next case management conference, iswhich was postponed until a to-be-determined date in either October or November 2023 (previously scheduled for June 27, 2023).

Claim brought by Royal Borough of Kensington and Chelsea and the Royal Borough of Kensington and Chelsea Tenant Management Organisation Ltd.

In 2020, a claim was issued by the Royal Borough of Kensington and Chelsea and the Royal Borough of Kensington and Chelsea Tenant Management Organisation Ltd against AAP SAS and other defendants seeking damages in respect of their own losses and/or a contribution to the extent that they are found to be liable by the London High Court for any losses arising out of the Grenfell Tower fire. These claims were stayed by the Court in order for the claimants and defendants to discuss alternate dispute resolution. Those alternate dispute resolutions discussions are ongoing though there is no certainty that such discussions will result in any settlement. Given the preliminary nature of these matters and the uncertainty of litigation, Arconic cannot reasonably estimate at this time the likelihood of an unfavorable outcome or the possible loss or range of losses in the event of an unfavorable outcome in the above-referenced disputes. The suits remain stayed until the next case management conference, iswhich was postponed until a to-be-determined date either in October or November 2023 (previously scheduled for June 27, 2023).

United States Litigation.

Behrens et al. v. Arconic Inc. et al. On June 6, 2019, 247 plaintiffs comprised of survivors and estates of decedents of the Grenfell Tower fire filed a complaint against “Arconic Inc., Alcoa Inc., and Arconic Architectural Products, LLC” (collectively, for purposes of the description of such proceeding, the “ParentCo Defendants”), as well as Saint-Gobain Corporation, d/b/a Celotex and Whirlpool Corporation, in the Court of Common Pleas of Philadelphia County. The complaint alleges claims under Pennsylvania state law for products liability and wrongful death related to the fire. In particular, the plaintiffs allege that the ParentCo Defendants knowingly supplied a dangerous product (Reynobond PE) for installation on the Grenfell Tower despite knowing that Reynobond PE was unfit for use above a certain height. The ParentCo Defendants removed the case to the United States District Court for the Eastern District of Pennsylvania on June 19, 2019. On August 29, 2019, the ParentCo Defendants moved to dismiss the complaint on the bases, among other things, that the case should be heard in the United Kingdom, not the United States. On September 16, 2020, the Court issued an order granting ParentCo Defendants’ motion to dismiss on forum non conveniens grounds, subject to certain conditions, determining that the United Kingdom, and not the United States, is the appropriate place for plaintiffs to bring their case. Plaintiffs appealed this judgment and ParentCo Defendants cross-appealed one of the conditions. On July 8, 2022, the Third Circuit decided the appeal in the Behrens matter in the ParentCo Defendants’ favor and invalidated one of the trial court’s dismissal conditions that would have left open the possibility for plaintiffs to return to the United States for a trial on damages. On January 5, 2023, the plaintiffs filed a petition seeking review in the U.S. Supreme Court. The Supreme Court denied that petition on February 21, 2023. This case is fully dismissed and closed.

Howard v. Arconic Inc. et al. A purported class action complaint related to the Grenfell Tower fire was filed on August 11, 2017 in the United States District Court for the Western District of Pennsylvania against ParentCo and Klaus Kleinfeld. A related purported class action complaint was filed in the United States District Court for the Western District of Pennsylvania on September 15, 2017, under the caption Sullivan v. Arconic Inc. et al., against ParentCo, three former ParentCo executives, several current and former ParentCo directors, and banks that acted as underwriters for ParentCo’s September 18, 2014

preferred stock offering (the “Preferred Offering”). The plaintiff in Sullivan had previously filed a purported class action against the same defendants on July 18, 2017 in the Southern District of New York and, on August 25, 2017, voluntarily dismissed that action without prejudice. On February 7, 2018, on motion from certain putative class members, the court consolidated Howard and Sullivan, closed Sullivan, and appointed lead plaintiffs in the consolidated case. On April 9, 2018, the lead plaintiffs in the consolidated purported class action filed a consolidated amended complaint. The consolidated amended complaint alleged that the registration statement for the Preferred Offering contained false and misleading statements and omitted to state material information, including by allegedly failing to disclose material uncertainties and trends resulting from sales of Reynobond PE for unsafe uses and by allegedly expressing a belief that appropriate risk management and compliance programs had been adopted while concealing the risks posed by Reynobond PE sales. The consolidated amended complaint also alleged that between November 4, 2013 and June 23, 2017 ParentCo and Kleinfeld made false and misleading statements and failed to disclose material information about ParentCo’s commitment to safety, business and financial prospects, and the risks of the Reynobond PE product, including in ParentCo’s Form 10-Ks for the fiscal years ended December 31, 2013, 2014, 2015, and 2016, its Form 10-Qs and quarterly financial press releases from the fourth quarter of 2013 through the first quarter of 2017, its 2013, 2014, 2015, and 2016 Annual Reports, its 2016 Annual Highlights Report, and on its official website. The consolidated amended complaint sought, among other things, unspecified compensatory damages and an award of attorney and expert fees and expenses. On June 8, 2018, all defendants moved to dismiss the consolidated amended complaint for failure to state a claim. On June 21, 2019, the Court granted the defendants’ motion to dismiss in full, dismissing the consolidated amended complaint in its entirety without prejudice. On July 23, 2019, the lead plaintiffs filed a second amended complaint. The second amended complaint alleges generally the same claims as the consolidated amended complaint with certain additional allegations, as well as claims that the risk factors set forth in the registration statement for the Preferred Offering were inadequate and that certain additional statements in the sources identified above were misleading. The second amended complaint seeks, among other things, unspecified compensatory damages and an award of attorney and expert fees and expenses. On September 11, 2019, all defendants moved to dismiss the second amended complaint. On June 23, 2021, the Court granted in part and denied in part the defendants’ motion to dismiss the second amended complaint. The Court dismissed with prejudice plaintiffs’ claim against ParentCo, certain officers and directors and the underwriters based on the registration statement for the Preferred Offering, with the exception of one statement and only as to purchases made before October 23, 2015. In addition, plaintiffs’ claim based on ParentCo’s statements in other SEC filings, in product brochures, and on websites was dismissed in its entirety as to Kleinfeld and dismissed in part and allowed in part as to ParentCo. The Court also dismissed the control-person liability claims in their entirety. The Court held a status conference on September 14, 2022, and on December 2, 2022, the Court issued an initial Case Management Order (“CMO”) setting forth dates for class certification briefing and discovery. In March 2023, following successive mediation sessions, the parties reached a settlement in principle that remains subject to court approval and, among other things, is to be covered by insurance proceeds, in exchange for the dismissal of the action and a release of all claims against the defendants. The settlement is without admission of fault or wrongdoing by the defendants. Plaintiffs filed a Stipulation of Settlement, a motion to preliminarily approve the settlement, and related papers with the court on April 21, 2023. On May 2, 2023, the court issued an order granting plaintiffs’ motion to preliminarily approve the settlement and setting August 9, 2023 as the date of the final settlement approval hearing. At March 31, 2023, Arconic recorded a $74 charge to Costs of goods sold to establish a reserve for the settlement and a $74 benefit to Cost of goods sold for a related receivable for costs to be covered by insurance proceeds. The reserve was reported in Other current liabilities and the receivable was reported in Prepaid expenses and other current assets on the accompanying Consolidated Balance Sheet.

Raul v. Albaugh, et al. On June 22, 2018, a derivative complaint was filed nominally on behalf of ParentCo by a purported ParentCo stockholder against the then members of ParentCo’s Board of Directors and Klaus Kleinfeld and Ken Giacobbe, naming ParentCo as a nominal defendant, in the United States District Court for the District of Delaware. The complaint raises similar allegations as the consolidated amended complaint and second amended complaint in Howard, as well as allegations that the defendants improperly authorized the sale of Reynobond PE for unsafe uses and asserts claims under Section 14(a) of the Securities Exchange Act of 1934, as amended, and Delaware state law. On July 13, 2018, the parties filed a stipulation agreeing to stay this case until the final resolution of the Howard case, the Grenfell Tower Public Inquiry in London, and the investigation by the Police and on July 23, 2018, the Court approved the stay. Given the preliminary nature of this matter and the uncertainty of litigation, Arconic Corporation cannot reasonably estimate at this time the likelihood of an unfavorable outcome or the possible loss or range of losses in the event of an unfavorable outcome.

General. While Arconic believes that all the above referenced Reynobond PE cases are without merit and intends to challenge them vigorously, there can be no assurances regarding the ultimate resolution of these matters.

the uncertainty of litigation, Arconic Corporation cannot reasonably estimate at this time the likelihood of an unfavorable outcome or the possible loss or range of losses in the event of an unfavorable outcome.

Tax. Under the terms of the agreements that govern the 2016 Separation Transaction, Arconic may be entitled to future economic benefits resulting from Alcoa Corporation’s utilization of certain value-added tax credits that were generated, in part, by the Company’s former operations in Brazil in years prior to 2015. Because Arconic is not party to the regulatory filings with the Brazilian government and, therefore, does not have a basis to conclude on the realizability of these value-added tax credits by Alcoa Corporation, the Company will recognize income when amounts are realized, if any.

Other. In 2018, Arconic entered into a consent order with the Iowa Department of Natural Resources (IDNR) to address overflows of stormwater combined with untreated process water from the Company’s Davenport plant which the IDNR alleged were unlawful bypasses prohibited by the facility’s wastewater discharge permit. These overflows occurred during periodic storm events that Arconic timely reported to the IDNR. The consent order required the Company to submit a feasibility study by November 1, 2022 evaluating the reasonableness, estimated cost, impact, and overall feasibility of all actions that could be implemented to avoid unlawful bypasses from occurring in the future. After conducting extensive monitoring, analysis, and investigative work, the Company submitted the feasibility study to the IDNR in October 2022. Arconic’s recommended approach, as documented in the feasibility study, consists of amending its wastewater discharge permit and constructing certain improvements to stormwater and process water systems expecting to result in estimated future capital expenditures of approximately $25 to $30, assuming Arconic’s approach is approved. In 2022, the Company established a reserve of $0.5 to cover future operating expenses associated with this proposed approach. On February 23, 2023, the IDNR informed Arconic of a regulatory approach that differs from Arconic’s proposed approach but that will require similar improvements. The Company now must submit a project schedule based on the IDNR’s approach by October 30, 2023. The consent order requires the Company to implement the approved remedy by November 1, 2028. Approval of a final remedy by the IDNR may result in additional expenditure and/or liability.

General. In addition to the matters described above, various other lawsuits, claims, and proceedings have been or may be instituted or asserted against Arconic, including those pertaining to environmental, product liability, safety and health, employment, tax, and antitrust matters. 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 reporting 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 results of operations, financial position or cash flows of Arconic.

Q. Financial Instruments

Amounts designated below as kmt are thousand metric tons, ~~and~~ MMBtu are million British thermal units, and MWh are megawatt hours.

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.

The respective carrying value and fair value of Arconic’s financial instruments were as follows:

	March 31, 2023				December 31, 2022
	June 30, 2023				December 31, 2022
	Carrying value		Fair value		Carrying value		Fair value
Cash and cash equivalents	$	~~197~~266	$	~~197~~266	$	261	$	261
Hedging instruments and derivatives - assets	753		753		21		21

Long-term debt	1,597		1,595		1,597		1,539

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

Cash and cash equivalents ~~and Short-term debt~~. The carrying amounts approximate fair value because of the short maturity of the instruments. The fair value amounts for Cash and cash equivalents were classified in Level 1 of the fair value hierarchy ~~and Short-term debt was classified in Level 2 of the fair value hierarchy~~.

Hedging instruments and derivatives. Arconic is exposed to certain risks relating to its ongoing business operations, including financial, market, political, and economic risks. Information regarding the Company’s exposure to risks of changing commodity prices is described below.

Arconic’s commodity and hedging activities are subject to the management, direction, and control of the Strategic Risk Management Committee (SRMC), which consists of at least three members, including the Company’s chief executive officer and chief financial officer. The remaining member(s) are other Arconic officers and/or employees as the chief executive officer may designate from time to time. Currently, the only other member of the SRMC is the Company’s treasurer. The SRMC meets on a periodic basis to review hedging positions and strategy and reports to the Audit and Finance Committee of Arconic’s Board of Directors on the scope of its activities.

The Company’s hedging instruments are held for purposes other than trading. They are used primarily to mitigate uncertainty and volatility, and to cover underlying exposures. Specifically, these instruments hedge forward sale commitments for aluminum and forward purchase commitments for aluminum, natural gas, and certain alloying materials. Arconic is not involved in trading activities for energy, weather derivatives, or other nonexchange commodity trading activities.

The fair value of the Company’s hedging instruments was based on quoted market prices (e.g., aluminum prices on the 10-year London Metal Exchange forward curve) and were classified in Level 1 of the fair value hierarchy. Most of these instruments are comprised of those that were designated as cash flow hedges while the remainder are marked-to-market as they do not qualify for hedge accounting.

Separately, Arconic has several natural gas supply contracts that are treated as derivatives for accounting purposes as they failed to qualify for the normal purchase normal sale exception due to net settlement provisions. These derivatives also do not qualify for hedge accounting. The Company does not have a regular practice of entering into contracts that are treated as derivatives for accounting purposes.

*In the 2022 first quarter, the Company recorded a net gain of $3 in Cost of goods sold related to the unrealized impact associated with the change in the estimated fair value of natural gas supply contracts determined to be derivatives. This amount was comprised of an unrealized loss of $5 for the 2022 first quarter, an unrealized gain of $6 for the 2021 annual period, and an unrealized gain of $2 for the 2020 fourth quarter. The out-of-period amounts were not material to any interim or annual period.

The disclosures with respect to commodity price risk do not consider the underlying commitments or anticipated transactions. If the underlying items were included, the gains or losses on the hedging instruments may be offset. Actual results will be determined by several factors that are not under Arconic’s control and could vary significantly from those factors disclosed.

29The Company is exposed to credit loss in the event of nonperformance by counterparties on the above instruments, as well as credit or performance risk with respect to its hedged customers’ commitments. Arconic does not anticipate nonperformance by any of these parties. Contracts are with creditworthy counterparties and may be further supported by cash or irrevocable letters of credit issued by carefully chosen banks. In addition, master netting arrangements are in place with counterparties to facilitate settlement of gains and losses on these contracts.

Long-term debt. The fair value was based on quoted market prices for public debt and was classified in Level 2 of the fair value hierarchy.

R. Working Capital Programs

Receivables. Arconic has two separate arrangements, each with a single financial institution, to sell certain customer receivables outright without recourse on a continuous basis. All such sales are at the Company’s discretion. The first arrangement, which was executed in January 2022, relates to certain of Arconic’s U.S. operations and automatically renews each year unless terminated in accordance with the provisions of the underlying purchase agreement. The second arrangement, which was executed in July 2022, relates to certain of the Company’s European operations. Under both arrangements, Arconic serves in an administrative capacity, including collection of the receivables from the respective customers and remittance of these cash collections to the respective financial institution. Accordingly, upon the sale of customer receivables to the financial institutions, the Company removes the underlying trade receivables from its Consolidated Balance Sheet and includes the reduction as a positive amount in the (Increase) in receivables line item within Operating Activities on its Statement of Consolidated Cash Flows. At no time can the outstanding balance due to the respective financial institution exceed $225 and $46 (€42.5) for the U.S. and European, respectively, arrangements. In the 2023 first quarter, Arconic sold customer receivables of $151, collected cash from customers of $129, and remitted cash collections to the financial institutions of $116. The $13 of cash collections yet to be remitted to the financial institutions was included in Accounts payable, trade on the accompanying Consolidated Balance Sheet as of March 31, 2023. In the first quarter of 2022, the Company sold customer receivables of $221 and remitted cash collections to the financial institution of $158 under the U.S. arrangement.

Supplier Finance Program. Arconic has an existing arrangement (capacity of approximately $250) with a financial institution to make available a finance program to the Company’s suppliers. Under this program, Arconic agrees to pay the financial institution the stated amount of confirmed invoices from its designated suppliers on the respective original maturity date of the invoices. The supplier invoices that have been confirmed as valid under the program require payment in full within no more than 120 days of the invoice date. The Company or the financial institution may terminate the arrangement upon at least 30 days’ notice. Arconic does not determine the terms or conditions of the arrangement between the financial institution and the suppliers nor does the Company participate in the transactions between its suppliers and the financial institution. As of March 31, 2023 and December 31, 2022, Arconic had outstanding obligations of $117 and $124, respectively, which have been confirmed as valid to the financial institution, under this program. These outstanding obligations were reported in Accounts payable, trade on the accompanying Consolidated Balance Sheet.

Accordingly, upon the sale of customer receivables to the financial institutions, the Company removes the underlying trade receivables from its Consolidated Balance Sheet and includes the reduction as a positive amount in the (Increase) in receivables line item within Operating Activities on its Statement of Consolidated Cash Flows. At no time can the outstanding balance due to the respective financial institution exceed $225 and $46 (€42.5) for the U.S. and European, respectively, arrangements. In the 2023 six-month period, Arconic sold customer receivables of $184 and remitted cash collections of $182 to the financial institutions. In the 2022 six-month period, the Company sold customer receivables of $550, collected cash from customers of $438, and remitted cash collections to the financial institution of $425 under the U.S. arrangement.

Supplier Finance Program. Arconic has an existing arrangement (capacity of $225 – reduced by $25 in the 2023 second quarter) with a financial institution to make available a finance program to the Company’s suppliers. Under this program, Arconic agrees to pay the financial institution the stated amount of confirmed invoices from its designated suppliers on the respective original maturity date of the invoices. The supplier invoices that have been confirmed as valid under the program require payment in full within no more than 120 days of the invoice date. The Company or the financial institution may terminate the arrangement upon at least 30 days’ notice. Arconic does not determine the terms or conditions of the arrangement between the financial institution and the suppliers nor does the Company participate in the transactions between its suppliers and the financial institution. As of June 30, 2023 and December 31, 2022, Arconic had outstanding obligations of $132 and $124, respectively, which have been confirmed as valid to the financial institution, under this program. These outstanding obligations were reported in Accounts payable, trade on the accompanying Consolidated Balance Sheet.

S. Subsequent Events

Management evaluated all activity of Arconic and concluded that no subsequent events have occurred that would require recognition in the Consolidated Financial Statements or disclosure in the Notes to the Consolidated Financial Statements, except as described below.

Proposed Merger

On May 4, 2023, Arconic entered into an Agreement and Plan of Merger (the “Merger Agreement”) to be acquired by funds managed by affiliates of Apollo Global Management, Inc. (“Apollo”), along with a minority investment from funds managed by affiliates of Irenic Capital Management LP (“Irenic”), in an all-cash transaction that values Arconic at an enterprise value of approximately $5.2,000 ~~billion.~~(the ~~The~~“Transaction” ~~transaction~~or ~~includes~~the ~~a minority investment from funds managed by affiliates of Irenic~~“Merger”). On the terms and subject to the conditions of the Merger Agreement, the Company’s stockholders will receive $30.00 per share in cash in exchange for each share of outstanding common stock. The ~~transaction~~Transaction is expected to close in the ~~second~~third ~~half~~quarter of 2023, subject to customary closing conditions, including approval by the Company’s stockholders. The Merger Agreement was adopted by the Company’s stockholders at a special meeting of the Company’s stockholders on July 25, 2023. Upon the closing of the ~~transaction~~Transaction, Arconic will operate as a privately-held company. In the 2023 second quarter, Arconic recognized $11 in Restructuring and other charges on the Company’s Statement of Consolidated Operations for incurred fees and expenses associated with the Transaction. Additional merger-related costs are expected to be recognized in a future period; however, such amounts are contingent on the outcome of the Transaction. Assuming the Transaction closes, the Company expects to recognize approximately $60 of additional acquisition-related expenses, which have not been accrued to date, associated with contractual agreements that are contingent upon the closing of the Transaction.

Results of Operations

Outlook

Management has revised certain expectations for sales by major end market, from what had been previously disclosed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II Item 7 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. Consistent with the disclosure included in the Form 10-K, the revised expectations do not include the impact of changes in aluminum prices.

•Ground Transportation: our sales outlook is relatively flat to an increase of approximately 5% (unchanged in 2023 first quarter) in 2023 compared with 2022 driven by continued strength in North American automotive, offset partly by weakness in European commercial transportation.

•Industrial Products: we lowered our sales outlook to reflect anticipated growth of approximately (5)% to 5% (versus prior expectation of relatively flat to 10%) in 2023 compared with 2022 due to continued softness in European demand and modest softening in North American demand.

•Building and Construction: our sales outlook is relatively flat to an increase of approximately 5% (unchanged in 2023 first quarter) in 2023 compared with 2022 driven by stable North American non-residential construction activity and expected improvement in European demand weakness in the second half of the year.

•Packaging: our sales outlook is an increase of approximately 5% to 10% (unchanged in 2023 first quarter) in 2023 compared with 2022 driven by expected growth in North American can sheet production.

•Aerospace: we raised our sales outlook to reflect anticipated growth of approximately 30% to 35% (versus prior expectation of 25% to 30%) in 2023 compared with 2022 due to a continued increase in production rates of large commercial aircraft by original equipment manufacturers.

Earnings Summary

Sales. Sales were $1,~~929~~990 in the 2023 ~~first~~second quarter compared to $2,~~191~~548 in the 2022 ~~first~~second quarter and $3,919 in the 2023 six-month period compared with $4,739 in the 2022 six-month period. The decrease of $~~262~~558, or 1222%, in the second quarter comparison and $820, or 17%, in the six-month period comparison was primarily due to the absence of sales ($~~233~~314 and $547 in the 2022 ~~first~~second quarter and six-month period, respectively) from Arconic’s former operations in Russia, which were sold in the 2022 fourth quarter (see Note O to the Consolidated Financial Statements in Part I Item 1 of this Form 10-Q), ~~and~~ lower aluminum prices, ~~somewhat~~and lower volumes, partially offset by favorable impacts from product pricing and product mix.

Cost of goods sold. COGS was $1,724, or 8986.46% of Sales, in the 2023 ~~first~~second quarter compared to $12,~~956~~258, or 8988.36% of Sales, in the 2022 ~~first~~second quarter and $3,448, or 88.0% ~~The~~of Sales, in the 2023 six-month period compared with $4,214, or 88.9% of Sales, in the 2022 six-month period. In the second quarter and six-month period comparisons, the percentage was ~~negatively~~positively impacted by favorable product pricing and lower aluminum prices, partially offset by higher costs for materials other than aluminum, labor and energy, and for the six-month period comparison, the carryover impact of the operational issues in the 2022 fourth quarter on the moving average costs of Arconic’s ~~North~~U.S. ~~America~~ rolling mills ~~in the 2023 first quarter~~. ~~These negative impacts were partially offset by favorable product pricing.~~

D&A was $52 in the 2023 second quarter compared to $62 in the 2022 second quarter and $105 in the 2023 six-month period compared to $122 in the 2022 six-month period. In the second quarter and six-month period comparisons, the decrease of $10, or 16%, and $17, or 14% was mainly due to the absence of depreciation resulting from the sale of Arconic’s operations in Russia in the 2022 fourth quarter ($7 and $13 in the 2022 second quarter and six-month period, respectively– see Note O to the Consolidated Financial Statements in Part I Item 1 of this Form 10-Q) and a decrease in amortization related to intangible assets.

Restructuring and other charges. Restructuring and other charges were not material in the 2023 first quarter and $5 in the 2022 first quarter. See Note E to the Consolidated Financial Statements in Part I Item 1 of this Form 10-Q for additional information. 34

~~Other~~Restructuring ~~expenses,~~and ~~net~~other charges. ~~Other~~Restructuring ~~expenses,~~and ~~net~~other ~~was~~charges were $119 in the 2023 ~~first~~second quarter and six-month period and $172 and $7 in the 2022 ~~first~~second quarter and six-month period, respectively.

The Company’s effective tax rate, including discrete items, was 22.4% and 24.3% in the 2023 second quarter and six-month period, respectively, and 24.8% and 24.2% in the 2022 second quarter and six-month period, respectively. See Note H to the Consolidated Financial Statements in Part I Item 1 of this Form 10-Q for additional information.

Segment Information

Arconic’s profit or loss measure for its reportable segments is Segment Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization). The Company calculates Segment Adjusted EBITDA as Total sales (third-party and intersegment) minus each of (i) Cost of goods sold, (ii) Selling, general administrative, and other expenses, and (iii) Research and development expenses, plus each of (i) Stock-based compensation expense, (ii) Metal price lag, and (iii) Unrealized (gains) losses on mark-to-market hedging instruments and derivatives (see below). Arconic’s Segment Adjusted EBITDA may not be comparable to similarly titled measures of other companies’ reportable segments.

These negative impacts were somewhat offset by favorable product mix driven by aerospace and price increases across most end markets.

~~The~~In the second quarter and six-month period comparisons, the lower aluminum prices were mostly driven by a 27decrease of 21% ~~decrease~~and 24%, respectively, in the average LME aluminum price and a decline in regional premiums, including a 22decrease of 32% ~~decrease~~and 27%, respectively, in the average Midwest premium (United States).

The net decrease in volumes of the ongoing operations in ~~the~~both ~~2023~~comparisons ~~first quarter compared with the 2022 first quarter~~ was mostly due to a decline in the industrial products end market caused by lower demand. Additionally, to a lesser extent, a decrease in volume related to both the packaging and building and construction end markets contributed to the decline in the second quarter and six-month period, respectively, comparisons. This lower volume was ~~mostly~~mainly ~~offset~~driven by ~~improvements~~weaker demand in Asia for the ~~aerospace,~~packaging ~~automotive~~end ~~component~~market ofand ~~ground~~in ~~transportation,~~both Europe and ~~packaging~~North America for the building and construction end ~~markets~~market. ~~Higher~~These ~~volume~~negative ~~associated~~impacts ~~with~~were partially offset by improvements in the ~~aerospace~~automotive ~~end~~component ~~market~~of ~~was~~the ~~driven~~ground bytransportation ~~continued~~end ~~recovery~~market ~~from~~and the ~~COVID-19~~aerospace ~~pandemic~~end market.

The increase in the 2023 six-month period comparison was mostly attributable to multiple product price increases implemented in 2021 and the 2022 first quarter across the entire portfolio to address inflationary cost pressures, partially offset by a decrease in volumes across the entire portfolio.

Segment Adjusted EBITDA for this segment remained flat and increased $10, or 2310%, in the 2023 ~~first~~second quarter and six-month period, respectively, compared with the corresponding ~~period~~periods in 2022. The 2023 second quarter comparison was impacted by favorable product pricing, offset by higher costs for alloying materials, maintenance, and labor, all due to inflation. The improvement in the 2023 six-month period was primarily related to favorable product pricing, partially offset by higher costs for alloying materials, maintenance, and ~~transportation~~labor, all due to inflation.

The Company was evaluating strategic options for the businesses that comprise the Building and Construction Systems segment. See Note O to the Consolidated Financial Statements in Part I Item 1 of this Form 10-Q for additional information.

Cash ~~used~~provided ~~for~~from operations was $39150 in the 2023 ~~three~~six-month period compared with ~~cash used for operations of~~ $~~103~~59 in the 2022 ~~three~~six-month period.

In the 2023 ~~three~~six-month period, cash ~~used~~provided ~~for~~from operations was mostly comprised of ~~an unfavorable change in working capital of $191, partially offset by~~ a positive add-back for non-cash transactions in earnings of $~~118~~212 and net income of $~~25.~~84, ~~The~~partially offset by an unfavorable change in working capital ~~includes a benefit~~ of $22 related to customer receivables sold to two financial institutions where the underlying trade receivables were uncollected as of March 31, 2023 (see Note R to the Consolidated Financial Statements in Part I Item 1 of this Form 10-Q)148.

Debt Activity—Arconic maintains a five-year credit agreement, dated May 13, 2020, with a syndicate of lenders named therein and Deutsche Bank AG New York Branch as administrative agent (the “ABL Credit Agreement”). The ABL Credit Agreement provides for a $1,200 senior secured asset-based revolving credit facility (the “ABL Credit Facility”) to be used, generally, for working capital or other general corporate purposes (available balance as of ~~March~~June 3130, 2023 was $1,~~134~~189 – see Note N to the Consolidated Financial Statements in Part I Item 1 of this Form 10-Q). See Note Q to the Consolidated Financial Statements in Part II Item 8 of Arconic’s Annual Report on Form 10-K for the year ended December 31, 2022 (filed on February 21, 2023) for additional information related to the ABL Credit Agreement.

In the 2023 ~~three~~six-month period, the Company borrowed $~~150~~175 and repaid $~~100~~175 under the ABL Credit Facility. These borrowings were designated as Secured Overnight Financing Rate (SOFR) loans with an initial one-month interest period. ~~Arconic may repay early or extend a part or all of these borrowings.~~ In the 2023 ~~three~~six-month period, the weighted-average interest rate and weighted-average days outstanding of the borrowings was 6.56% and 3055 days, respectively. In March 2022, the Company borrowed $100 under the ABL Credit Facility. This borrowing was designated as a SOFR loan with an initial three-month interest period. AsIn ofJune ~~March 31,~~ 2022, the Company extended this borrowing for an additional three-month period. The applicable rate on this borrowing was 2.50% through June 15, 2022 and 4.22% beginning June 16, 2022. On June 30, 2022, Arconic repaid early $50 of this borrowing.

Share Repurchase Programs—On November 16, 2022, Arconic announced that its Board of Directors approved a share repurchase program authorizing the Company to repurchase shares of its outstanding common stock up to an aggregate transactional value of $200 over a two-year period expiring November 17, 2024 (see Part II Item 2 in this Form 10-Q for additional information). In the 2023 ~~three~~six-month period, Arconic repurchased 35,615 shares of the Company’s common stock for $1 under this program.

36On May 4, 2021, Arconic announced that its Board of Directors approved a share repurchase program authorizing the Company to repurchase shares of its outstanding common stock up to an aggregate transactional value of $300 over a two-year period expiring April 28, 2023. In the 2022 second quarter and six-month period, Arconic repurchased 1,324,027 and 1,830,009 shares, respectively, of the Company's common stock for $37 and $53, respectively, under this program. Cumulatively, Arconic repurchased 9,776,177 shares of the Company’s common stock for $300, resulting in the completion of the total authorization under this program in August 2022.

Investing Activities

Cash used for investing activities was $75132 in the 2023 ~~three~~six-month period compared with $94127 in the 2022 ~~three~~six-month period. The use of cash in the 2023 ~~three~~six-month period was primarily due to $82139 in capital expenditures, mostly due to sustaining spend at the U.S. rolling mills, slightly offset by proceeds received related to an eminent domain proceeding against land owned by Arconic. The use of cash in the 2022 ~~three~~six-month period was primarily due to $95128 in capital expenditures, mostly due to growth spend at the U.S. rolling mills.

Except as set forth below, there have been no material changes in the Company’s risk factors from those disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

Risks Related to the Proposed Merger

The announcement and pendency of the ~~proposed~~Merger ~~acquisition of the Company~~ could adversely impact the Company’s business, financial condition, and results of operations.

On May 4, 2023, the Company entered into an Agreement and Plan of Merger with Arsenal AIC Parent LLC (“Parent”) and Arsenal AIC MergeCo Inc. (“Merger Sub”), funds managed by affiliates of Apollo and Irenic, pursuant to and subject to the terms of which Merger Sub will merge with and into the Company, with the Company surviving as a wholly-owned subsidiary of Parent (the “Merger”). Uncertainty about the effect of the Merger on the Company’s employees, customers, and other parties may have an adverse effect on the Company’s business, financial condition, and results of operation regardless of whether the Merger is completed. These risks to the Company’s business include the following, all of which could be exacerbated by a delay in the completion of the Merger:

•the impairment of the Company’s ability to attract, retain, and motivate its employees, including key personnel;

•the diversion of significant management time and resources towards the completion of the Merger;

•difficulties maintaining relationships with customers, suppliers, and other business partners;

•delays or deferments of certain business decisions by the Company’s customers, suppliers, and other business partners;

•the inability to pursue alternative business opportunities or make appropriate changes to the Company’s business because the Merger Agreement requires the Company to use reasonable best efforts to conduct its business in the ordinary course, use commercially reasonable efforts to preserve its business organization intact and maintain existing relations with key customers, suppliers, lenders, partners, officers, employees, governmental entities and other third parties with whom the Company and its subsidiaries have significant business relationships or regulatory relationships, and refrain from taking certain actions ~~without Parent’s consent~~ prior to the completion of the Merger;

•litigation relating to the Merger and the costs related thereto; and

•the incurrence of significant costs, expenses, and fees for professional services and other transaction costs in connection with the Merger.

Litigation relating to the Merger ~~may~~has bebeen filed against the Company and its Board of Directors, and demand letters have been received by the Company, which could prevent or delay the completion of the Merger or result in the payment of damages.

~~Litigation~~In ~~relating~~connection towith the Merger, ~~may~~complaints behave been filed ~~against~~in ~~the~~federal ~~Company~~court ~~and~~as ~~its~~individual ~~Board~~actions. ofThe ~~Directors~~complaints are captioned O’Dell v. ~~Among~~Arconic ~~other~~Corporation, ~~remedies~~et al., ~~these~~1:23-cv-04971 ~~claimants~~(S.D.N.Y. ~~could~~June ~~seek~~13, ~~damages~~2023); ~~and/or~~Wang tov. ~~enjoin~~Arconic ~~the~~Corporation, ~~Merger~~et ~~and~~al., ~~the~~1:23-cv-05091 ~~other~~(S.D.N.Y. ~~transactions~~June ~~contemplated~~16, by2023); ~~the~~Bushansky ~~Merger~~v. ~~Agreement~~Arconic Corporation, et al., ~~The~~1:23-cv-05167 ~~outcome~~(S.D.N.Y. ofJune ~~any~~19, ~~litigation~~2023); isWilliams ~~uncertain~~v.

The Complaints seek, among other things: (a) an injunction enjoining the consummation of the Merger; (b) rescission or rescissory damages in the event the Merger is consummated; (c) direction that defendants account for all damages suffered as a result of any misconduct; (d) direction that defendants file a proxy statement that does not contain alleged misstatements and/or omissions; (e) a declaration that defendants violated Sections 14(a) and/or 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder; (f) a declaration that defendants violated 70 P.S. § 1-401 and/or Pennsylvania common law; (g) an award of punitive damages, as allowed by law; (h) costs of the action, including reasonable plaintiffs’ attorneys’ fees and experts’ fees and expenses; and (i) other relief the court may deem just and proper.

Failure to consummate the Merger within the expected timeframe or at all could adversely impact the Company’s business, financial condition, and results of operations.

The completion of the Merger is subject to the satisfaction or waiver of certain customary mutual closing conditions, including the absence of any injunction by any court or other tribunal of competent jurisdiction, or adoption of any law, that prohibits or makes the consummation of the Merger illegal and the receipt of certain regulatory approvals. The obligation of each party to consummate the Merger is also conditioned upon certain unilateral closing conditions, including the other party’s representations and warranties being accurate (subject to certain customary materiality exceptions) and the other party having in all material respects performed and complied with its covenants in the Merger Agreement. There can be no assurance that these conditions will be satisfied in a timely manner or at all or that the Merger will be completed.

If the Merger is not completed, the Company’s stockholders will not receive any payment for their shares in connection with the Merger. Instead, the Company will remain an independent public company, and the shares will continue to be traded on the New York Stock Exchange. The Company’s ongoing business may be materially adversely affected, and the Company would be subject to a number of risks, including the following:

•the Company may experience negative publicity, which could have an adverse effect on its ongoing operations including, but not limited to, retaining and attracting customers, suppliers, and other business partners;

•the Company would incur significant costs in future periods relating to the Merger, such as legal, accounting, financial advisor, printing, and other professional services fees, which may relate to activities that the Company would not have undertaken other than to complete the Merger;

•the Company may be required to pay a cash termination fee as required under the Merger Agreement, which may require the Company to use available cash that would have otherwise been available for general corporate purposes or other uses and could affect the structure, pricing and terms proposed by a third party seeking to acquire or merge with the Company or deter such third party from making a competing acquisition proposal; and

•the Merger Agreement places certain restrictions on the conduct of the Company’s business, which may have delayed or prevented the Company from undertaking business opportunities that, absent the Merger Agreement, it may have pursued.

If the Merger is not consummated, the risks described above may materialize and they may have a material adverse effect on the Company’s business operations, financial condition, results of operations, and stock price, especially to the extent that the current market price of the Company’s common stock reflects an assumption that the Merger will be completed.

* On November 16, 2022, Arconic announced that its Board of Directors approved a share repurchase program authorizing the Company to repurchase up to $200 million of common stock for a two-year period expiring November 17, 2024. Repurchases under the program may be made from time to time, as the Company deems appropriate, based on a variety of factors such as price, capital position, liquidity, financial performance, alternative uses of capital, and overall market conditions. There can be no assurance as to the number of shares the Company will purchase, if any. The share repurchase program may be increased or otherwise modified, renewed, suspended, or terminated by the Company at any time, without prior notice. In connection with the establishment of this share repurchase program, the prior $300 million repurchase program, which the Company completed in August 2022, was terminated. This program is intended to comply with Rule 10b5-1 and all purchases shall be made in compliance with Rule 10b-18, including without limitation the timing, price, and volume restrictions thereof.
