COMMON STOCK OUTSTANDING AT THE END OF THE PERIOD

Prior to April 1, 2020, Arconic Corporation’s financial statements were prepared on a carve-out basis, as the underlying operations of the Company were previously consolidated as part of Arconic Corporation’s former parent company’s financial statements. Accordingly, the Company’s results of operations for the quarter ended December 31, 2019 were prepared on such basis. The carve-out financial statements of Arconic Corporation are not necessarily indicative of the Company’s consolidated results of operations had it been a standalone company during the referenced period. See the Combined Financial Statements included in each of (i) Exhibit 99.1 to Arconic Corporation’s Form 10 Registration Statement (filed on February 7, 2020), (ii) the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (filed on March 30, 2020), and (iii) the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2020 (filed on May 18, 2020), for additional information.

In preparation for the separation of Arconic Corporation from its former parent company, effective January 1, 2020, certain U.S. defined benefit pension and other postretirement plans previously sponsored by the former parent company were separated into standalone plans for both Arconic Corporation and the former parent company. Additionally, effective April 1, 2020, Arconic Corporation assumed a portion of the obligations associated with certain non-U.S. defined benefit pension plans that included participants related to both Arconic Corporation and its former parent company, as well as legacy defined benefit pension plans assigned to the Company as a result of the separation from the former parent company. As a result, beginning in the first quarter of 2020 for these U.S. plans and in the second quarter of 2020 for these non-U.S. plans, Arconic Corporation applied defined benefit plan accounting resulting in benefit plan expense being recorded in operating income (service cost) and nonoperating income (nonservice cost). In all historical periods prior to these respective timeframes, Arconic Corporation was considered a participating employer in the former parent company’s defined benefit plans and, therefore, applied multiemployer plan accounting resulting in the Company’s share of benefit plan expense being recorded entirely in operating income. Also, Arconic Corporation is the plan sponsor of certain other non-U.S. defined benefit plans that contain participants related only to the underlying operations of the Company and, therefore, the related benefit plan expense was recorded in accordance with defined benefit plan accounting in all periods presented. The following table presents the total benefit plan expense (excluding settlements and curtailments) recorded by Arconic Corporation based on the foregoing in each period presented:

Cost of goods sold (exclusive of expenses below)

Effective July 1, 2020, the Company changed its inventory cost method to average cost for all U.S. inventories previously carried at last-in, first-in (LIFO) cost. Management believes the average cost method more closely reflects the physical flow of inventories, improves comparability of the Company’s operating results with its industry peers, and provides an increased level of consistency in the measurement of inventories in the Company’s consolidated financial statements. The effects of the change in accounting principle from LIFO to average cost have been retrospectively applied to the Company’s Statement of Consolidated Operations for the quarter ended December 31, 2019. Accordingly, Net income attributable to Arconic Corporation decreased $18 (comprised of a $23 increase to Cost of goods sold and a $5 increase to Benefit for income taxes), or $0.17 per share, from the amount previously reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (filed on March 30, 2020). See the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional information.

In the quarter ended December 31, 2020, Restructuring and other charges includes a $140 settlement charge related to the annuitization of a portion of the Company’s U.S. defined benefit pension plan obligation and a $25 benefit for contingent consideration received related to the October 2018 sale of the Texarkana (Texas) rolling mill. In the quarter ended December 31, 2019, Restructuring and other charges includes a $20 benefit for contingent consideration received related to the October 2018 sale of the Texarkana (Texas) rolling mill.

In the quarter ended December 31, 2020, Other expenses (income), net includes a $20 benefit for the reversal of a liability previously established on April 1, 2020 related to a potential indemnification to Howmet Aerospace by Arconic Corporation for an outstanding income tax matter in Spain. In November 2020, Howmet Aerospace received a favorable ruling from Spain’s Supreme Court bringing a final conclusion to this matter as this decision may not be appealed any further. As no further income tax payment was required of Howmet Aerospace likewise Arconic Corporation no longer has a requirement to perform under the indemnification.

In the quarter ended December 31, 2020, the diluted weighted-average number of shares does not include any common share equivalents associated with outstanding employee stock awards as their effect was anti-dilutive since the Company generated a net loss for the period. In the quarter ended September 30, 2020, the difference between the diluted weighted-average number of shares and the basic weighted-average number of shares relates to common share equivalents associated with outstanding employee stock awards. Prior to April 1, 2020, the Company did not have any publicly-traded issued and outstanding common stock or any common share equivalents. Accordingly, the respective basic and diluted earnings per share for the quarter ended December 31, 2019 were calculated based on the 109,021,376 shares of Arconic Corporation common stock distributed on April 1, 2020 in connection with the completion of Arconic Corporation’s separation from its former parent company.

COMMON STOCK OUTSTANDING AT THE END OF THE PERIOD

Prior to April 1, 2020, Arconic Corporation’s financial statements were prepared on a carve-out basis, as the underlying operations of the Company were previously consolidated as part of Arconic Corporation’s former parent company’s financial statements. Accordingly, the Company’s results of operations for the first three months included in the year ended December 31, 2020 and all months included in the year ended December 31, 2019 were prepared on such basis. The carve-out financial statements of Arconic Corporation are not necessarily indicative of the Company’s consolidated results of operations had it been a standalone company during the referenced periods. See the Combined Financial Statements included in each of (i) Exhibit 99.1 to Arconic Corporation’s Form 10 Registration Statement (filed on February 7, 2020), (ii) the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (filed on March 30, 2020), and (iii) the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2020 (filed on May 18, 2020), for additional information.

See the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional information.

In the year ended December 31, 2020, Restructuring and other charges includes a $198 settlement charge related to the annuitizations of a portion of the Company’s U.S. and U.K. defined benefit pension plan obligations and a $25 benefit for contingent consideration received related to the October 2018 sale of the Texarkana (Texas) rolling mill. In the year ended December 31, 2019, Restructuring and other charges includes a $20 benefit for contingent consideration received related to the October 2018 sale of the Texarkana (Texas) rolling mill.

Prior to April 1, 2020, Arconic Corporation’s financial statements were prepared on a carve-out basis, as the underlying operations of the Company were previously consolidated as part of Arconic Corporation’s former parent company’s financial statements. Accordingly, the Company’s financial position as of December 31, 2019 was prepared on such basis. The carve-out financial statements of Arconic Corporation are not necessarily indicative of the Company’s financial position had it been a standalone company during the referenced period. See the Combined Financial Statements included in each of (i) Exhibit 99.1 to Arconic Corporation’s Form 10 Registration Statement (filed on February 7, 2020), (ii) the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (filed on March 30, 2020), and (iii) the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2020 (filed on May 18, 2020), for additional information.

Prior to January 1, 2020, certain of Arconic Corporation’s customer receivables were sold to its former parent company, which had an arrangement with several financial institutions to sell certain customer receivables without recourse on a revolving basis. As of December 31, 2019, the amount of Arconic Corporation’s outstanding customer receivables sold to its former parent company was $281. In preparation for the separation of Arconic Corporation from its former parent company, effective January 2, 2020, the former parent company’s arrangement was amended to no longer include customer receivables associated with Arconic Corporation in this program.

Effective July 1, 2020, the Company changed its inventory cost method to average cost for all U.S. inventories previously carried at last-in, first-in (LIFO) cost. Management believes the average cost method more closely reflects the physical flow of inventories, improves comparability of the Company’s operating results with its industry peers, and provides an increased level of consistency in the measurement of inventories in the Company’s consolidated financial statements. The effects of the change in accounting principle from LIFO to average cost have been retrospectively applied to the Company’s Consolidated Balance Sheet as of December 31, 2019. Accordingly, Inventories, Deferred income taxes, and Parent Company net investment increased $317, $72, and $245, respectively, from amounts previously reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (filed March 30, 2020). The increase to Parent Company net investment includes a cumulative effect of accounting change of $293 recorded on January 1, 2019. See the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional information.

Effective July 1, 2020, the Company changed its inventory cost method to average cost for all U.S. inventories previously carried at last-in, first-in (LIFO) cost. Management believes the average cost method more closely reflects the physical flow of inventories, improves comparability of the Company’s operating results with its industry peers, and provides an increased level of consistency in the measurement of inventories in the Company’s consolidated financial results. The effects of the change in accounting principle from LIFO to average cost have been retrospectively applied to the Company’s Statement of Consolidated Cash Flows for the quarter ended June 30, 2020. Accordingly, Net loss increased $4, Deferred income taxes decreased $1, and Decrease in inventories positively changed by $5. See the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional information.

In preparing the Statement of Consolidated Cash Flows for the nine months ended September 30, 2020, management discovered that the amount of (Decrease) in account payable, trade previously reported for the quarter ended June 30, 2020 was overstated by $8 and the amount of Capital expenditures previously reported for the quarter ended June 30, 2020 was understated by $8. As a result, for the quarter ended June 30, 2020, management has corrected both (Decrease) in accounts payable, trade and Capital expenditures from previously reported amounts to remove the respective effect of this $8. Additionally, financial information for prior periods not presented herein will be corrected, as applicable, in future filings.

On April 1, 2020, Arconic Inc. separated into two standalone, publicly-traded companies, Arconic Corporation and Howmet Aerospace Inc. (the “Separation”). In connection with the capital structure to be established at the time of the Separation, Arconic Corporation secured $1,200 in third-party indebtedness during the first quarter of 2020. The net proceeds from a portion of this indebtedness was held in escrow until the satisfaction of the escrow release conditions, which included the substantially concurrent completion of the Separation. Accordingly, the escrowed cash was included in Restricted cash as of March 31, 2020 (see footnote 4). The Company used a portion of the net proceeds from the aggregate indebtedness to make a $728 payment to its former parent company on April 1, 2020 to fund the transfer of certain net assets from the former parent company to Arconic Corporation in connection with the completion of the Separation. On April 2, 2020, Arconic Corporation incurred an additional $500 of indebtedness as a proactive measure taken by the Company to bolster its liquidity and preserve financial flexibility in light of uncertainties resulting from the COVID-19 outbreak. On May 13, 2020, in order to provide improved financial flexibility, Arconic Corporation executed a refinancing of a portion of its outstanding indebtedness by securing $700 in new third-party indebtedness. The Company used the net proceeds from the new indebtedness, together with cash on hand, to repay $1,100 of outstanding indebtedness.

Cash and cash equivalents and restricted cash at beginning of period for the quarters ended December 31, 2020 and September 30, 2020 and Cash and cash equivalents and restricted cash at end of period for all periods includes Restricted cash of less than $0.03. For the quarter ended June 30, 2020, Cash and cash equivalents and restricted cash at beginning of period includes Restricted cash of $593 (see footnote 3).

Prior to April 1, 2020, Arconic Corporation’s financial statements were prepared on a carve-out basis, as the underlying operations of the Company were previously consolidated as part of Arconic Corporation’s former parent company’s financial statements. Accordingly, the Company’s results of operations for the quarter ended December 31, 2019 were prepared on such basis. The carve-out financial statements of Arconic Corporation are not necessarily indicative of the Company’s consolidated results of operations had it been a standalone company during the referenced period. See the Combined Financial Statements included in each of (i) Exhibit 99.1 to Arconic Corporation’s Form 10 Registration Statement (filed on February 7, 2020), (ii) the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (filed on March 30, 2020), and (iii) the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2020 (filed on May 18, 2020), for additional information.

Effective in the second quarter of 2020, management elected to change the profit or loss measure of the Company’s reportable segments from Segment operating profit to Segment Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) for internal reporting and performance measurement purposes. This change was made to enhance the transparency and visibility of the underlying operating performance of each segment. Effective in the third quarter of 2020, management refined the Company’s Segment Adjusted EBITDA measure to remove the impact of metal price lag (see footnote 6). This change was made to further enhance the transparency and visibility of the underlying operating performance of each segment by removing the volatility associated with metal prices.

Arconic Corporation 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) and Research and development expenses, plus Stock-based compensation expense and Metal price lag. Previously, the Company calculated Segment operating profit as Segment Adjusted EBITDA minus each of (i) the Provision for depreciation and amortization, (ii) Stock-based compensation expense, and (iii) Metal price lag. Arconic Corporation’s Segment Adjusted EBITDA may not be comparable to similarly titled measures of other companies’ reportable segments.

Also, effective July 1, 2020, the Company changed its inventory cost method to average cost for all U.S. inventories previously carried at last-in, first-in (LIFO) cost. The effects of the change in accounting principle have been retrospectively applied to the Company’s Statement of Consolidated Operations for the quarter ended December 31, 2019. See footnote 4 for additional information.

Segment Adjusted EBITDA for the quarter ended December 31, 2019 was recast to reflect the new measure of segment profit or loss and the change in inventory cost method.

Total Segment Adjusted EBITDA is the sum of the respective Segment Adjusted EBITDA for each of the Company's three reportable segments: Rolled Products, Building and Construction Systems, and Extrusions. This amount is being presented for the sole purpose of reconciling Segment Adjusted EBITDA to the Company's Consolidated net (loss) income.

In preparation for the separation of Arconic Corporation from its former parent company, effective January 1, 2020, certain U.S. defined benefit pension and other postretirement plans previously sponsored by the former parent company were separated into standalone plans for both Arconic Corporation and the former parent company. Additionally, effective April 1, 2020, Arconic Corporation assumed a portion of the obligations associated with certain non-U.S. defined benefit pension plans that included participants related to both Arconic Corporation and its former parent company, as well as legacy defined benefit pension plans assigned to the Company as a result of the separation from the former parent company. As a result, beginning in the first quarter of 2020 for these U.S. plans and in the second quarter of 2020 for these non-U.S. plans, Arconic Corporation applied defined benefit plan accounting resulting in benefit plan expense being recorded in operating income (service cost) and nonoperating income (nonservice cost). In all historical periods prior to these respective timeframes, Arconic Corporation was considered a participating employer in the former parent company’s defined benefit plans and, therefore, applied multiemployer plan accounting resulting in the Company’s share of benefit plan expense being recorded entirely in operating income. Also, Arconic Corporation is the plan sponsor of certain other non-U.S. defined benefit plans that contain participants related only to the underlying operations of the Company and, therefore, the related benefit plan expense was recorded in accordance with defined benefit plan accounting in all periods presented. The following table presents the total benefit plan expense (excluding settlements and curtailments) recorded by Arconic Corporation based on the foregoing in each period presented:

Total Segment Adjusted EBITDA

Unallocated amounts:

Corporate expenses

Effective July 1, 2020, the Company changed its inventory cost method to average cost for all U.S. inventories previously carried at LIFO cost. Management believes the average cost method more closely reflects the physical flow of inventories, improves comparability of the Company’s operating results with its industry peers, and provides an increased level of consistency in the measurement of inventories in the Company’s consolidated financial statements. The effects of the change in accounting principle from LIFO to average cost have been retrospectively applied to the Company’s Statement of Consolidated Operations for the quarter ended December 31, 2019. Accordingly, Net income attributable to Arconic Corporation decreased $18 (comprised of a $23 increase to Cost of goods sold and a $5 increase to Benefit for income taxes) from the amount previously reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (filed on March 30, 2020). See the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional information.

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. The amount presented for the quarter ended December 31, 2019 represents an allocation of Arconic Corporation’s former parent company’s corporate expenses (see footnote 1).

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.

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, including those described as “Other special items” (see footnote 5 to the reconciliation of Adjusted EBITDA within Calculation of Non-GAAP Financial Measures included in this release).

Adjusted EBITDA Margin

Arconic Corporation’s definition of Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) is net margin plus an add-back for the following items: Provision for depreciation and amortization; Stock-based compensation; Metal price lag (see below); and Other special items. Net margin is equivalent to Sales minus the following items: Cost of goods sold; Selling, general administrative, and other expenses; Research and development expenses; and Provision for depreciation and amortization. Special items are composed of restructuring and other charges, discrete income tax items, and other items as deemed appropriate by management. There can be no assurances that additional special items will not occur in future periods. Adjusted EBITDA is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because Adjusted EBITDA provides additional information with respect to Arconic Corporation’s operating performance and the Company’s ability to meet its financial obligations. The Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies.

Effective in the third quarter of 2020, management refined the Company’s Adjusted EBITDA measure to remove the impact of metal price lag (see footnote 4). This change was made to further enhance the transparency and visibility of the underlying operating performance of the Company by removing the volatility associated with metal prices. Also, effective July 1, 2020, the Company changed its inventory cost method to average cost for all U.S. inventories previously carried at last-in, first-in (LIFO) cost. The effects of the change in accounting principle have been retrospectively applied to the Company’s Statement of Consolidated Operations for the quarter and year ended December 31, 2019. See footnote 2 for additional information. Adjusted EBITDA for the quarter and year ended December 31, 2019 was recast to reflect both these changes.

Prior to April 1, 2020, Arconic Corporation’s financial statements were prepared on a carve-out basis, as the underlying operations of the Company were previously consolidated as part of Arconic Corporation’s former parent company’s financial statements. Accordingly, the Company’s results of operations for the quarter ended December 31, 2019, the first three months included in the year ended December 31, 2020, and all months included in the year ended December 31, 2019 were prepared on such basis. The carve-out financial statements of Arconic Corporation are not necessarily indicative of the Company’s consolidated results of operations had it been a standalone company during the referenced periods. See the Combined Financial Statements included in each of (i) Exhibit 99.1 to Arconic Corporation’s Form 10 Registration Statement (filed on February 7, 2020), (ii) the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (filed on March 30, 2020), and (iii) the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2020 (filed on May 18, 2020), for additional information.

Effective July 1, 2020, the Company changed its inventory cost method to average cost for all U.S. inventories previously carried at LIFO cost. Management believes the average cost method more closely reflects the physical flow of inventories, improves comparability of the Company’s operating results with its industry peers, and provides an increased level of consistency in the measurement of inventories in the Company’s consolidated financial statements. The effects of the change in accounting principle from LIFO to average cost have been retrospectively applied to the Company’s Statement of Consolidated Operations for the quarter and year ended December 31, 2019. Accordingly, for the quarter ended December 31, 2019, Net income attributable to Arconic Corporation decreased $18 (comprised of a $23 increase to Cost of goods sold and a $5 increase to Benefit for income taxes) from the amount previously reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (filed on March 30, 2020). Additionally, for the year ended December 31, 2019, Net income attributable to Arconic Corporation decreased $48 (comprised of a $62 increase to Cost of goods sold and a $14 increase to Benefit for income taxes) from the amount previously reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (filed on March 30, 2020). See the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 for additional information.

In preparation for the separation of Arconic Corporation from its former parent company, effective January 1, 2020, certain U.S. defined benefit pension and other postretirement plans previously sponsored by the former parent company were separated into standalone plans for both Arconic Corporation and the former parent company. Additionally, effective April 1, 2020, Arconic Corporation assumed a portion of the obligations associated with certain non-U.S. defined benefit pension plans that included participants related to both Arconic Corporation and its former parent company, as well as legacy defined benefit pension plans assigned to the Company as a result of the separation from the former parent company. As a result, beginning in the first quarter of 2020 for these U.S. plans and in the second quarter of 2020 for these non-U.S. plans, Arconic Corporation applied defined benefit plan accounting resulting in benefit plan expense being recorded in operating income (service cost) and nonoperating income (nonservice cost). In all historical periods prior to these respective timeframes, Arconic Corporation was considered a participating employer in the former parent company’s defined benefit plans and, therefore, applied multiemployer plan accounting resulting in the Company’s share of benefit plan expense being recorded entirely in operating income. Also, Arconic Corporation is the plan sponsor of certain other non-U.S. defined benefit plans that contain participants related only to the underlying operations of the Company and, therefore, the related benefit plan expense (excluding settlements and curtailments) was recorded in accordance with defined benefit plan accounting in all periods presented. See footnote 2 to the Statement of Consolidated Operations included in this release for additional information.

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.

Long-term debt

Short-term borrowings

Total debt

Less: Cash and cash equivalents

Net debt

Net debt is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management assesses Arconic Corporation’s leverage position after considering available cash that could be used to repay outstanding debt. Long-term debt equals $1,300 principal of outstanding indebtedness less $22 of unamortized debt issuance costs.
