Important Information (cont’d) 3 Non-GAAP Financial Measures Some of the information included in
this presentation is derived from Arconic’s consolidated financial information but is not presented in Arconic’s financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP).
Certain of these financial measures are considered “non-GAAP financial measures” under SEC rules. These non-GAAP financial measures supplement our GAAP disclosures and should not be considered an alternative to any measure of performance or
financial condition as determined in accordance with GAAP, and investors should consider Arconic’s performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial
condition of Arconic. Non-GAAP financial measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the results or financial condition as reported under GAAP. Non-GAAP
financial measures presented by Arconic may not be comparable to non-GAAP financial measures presented by other companies. Reconciliations to the most directly comparable GAAP financial measures and management’s rationale for the use of the
non-GAAP financial measures can be found in the appendix to this presentation. Arconic has not provided reconciliations of any forward-looking non-GAAP financial measures, such as adjusted EBITDA, and free cash flow, to the most directly
comparable GAAP financial measures because such reconciliations are not available without unreasonable efforts due to the variability and complexity with respect to the charges and other components excluded from the non-GAAP measures, such as
the effects of metal price lag, foreign currency movements, gains or losses on sales of assets, taxes, and any future restructuring or impairment charges. These reconciling items are in addition to the inherent variability already included in
the GAAP measures, which includes, but is not limited to, price/mix and volume. Arconic believes such reconciliations would imply a degree of precision that would be confusing or misleading to investors.

interest – – – Consolidated net loss attributable to Arconic Corporation $ (273) $ (65) $ (38) Reconciliation of Segment Adjusted EBITDA 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 (see footnote 3), 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. Effective in the first quarter of 2022, management modified the Company’s definition of Segment
Adjusted EBITDA to exclude the impact of unrealized gains and losses on mark-to-market hedging instruments and derivatives. This modification was deemed appropriate as Arconic is considering entering into additional hedging instruments in
future reporting periods if favorable conditions exist to mitigate cost inflation. Certain of these instruments may not qualify for hedge accounting resulting in unrealized gains and losses being recorded directly to Sales or Cost of goods
sold, as appropriate (i.e., mark-to-market). Additionally, this change was also applied to derivatives that do not qualify for hedge accounting for consistency purposes. The Company does not have a regular practice of entering into contracts
that are treated as derivatives for accounting purposes. Ultimately, this change was made to maintain the transparency and visibility of the underlying operating performance of Arconic’s reportable segments. Prior to this change, the Company
had a limited number of hedging instruments and derivatives that did not qualify for hedge accounting, the unrealized impact of which was not material to Arconic’s Segment Adjusted EBITDA performance measure. Accordingly, periods prior to the
effective date of this change were not recast to reflect this change. 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. Corporate expenses are composed of general administrative and other
expenses of operating the corporate headquarters and other global administrative facilities. 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. In the
quarter ended December 31, 2021, Arconic completed its annual review of goodwill for impairment for each of its three reporting units: Rolled Products, Building and Construction Systems, and Extrusions. The results of this review indicated
that the carrying value of the Extrusions reporting unit’s goodwill was fully impaired. Accordingly, in the quarter ended December 31, 2021, the Company recognized an impairment charge of $65. This impairment was primarily driven by a
combination of market-based factors, including delays in aerospace market improvement and significant cost inflation, resulting in increasingly limited margin expansion. The Company had not previously identified any triggering events during
2021 prior to the annual review.
14 Reconciliation of Segment Adjusted EBITDA (cont’d) On November 15, 2022, Arconic completed the
sale of 100% of its operations in Russia to Promishlennie Investitsii LLC, the majority owner of VSMPO-AVISMA Corporation, for cash proceeds of $230. The transaction closed after the Company received all required approvals, resulting in the
receipt of the cash consideration in exchange for all of Arconic’s net assets in Russia. These net assets included $203 of cash held in Russia that was not available for distribution to the parent company because of injunctions imposed as a
result of litigation initiated in March 2020 by the Federal Antimonopoly Service of The Russian Federation (“FAS”). The Company recorded a loss of $306 ($304 after-tax) in connection with this transaction. At a hearing on December 22, 2022,
the Samara Court dismissed the litigation. In the quarter ended September 30, 2022, the Company updated its five-year strategic plan, the results of which indicated that there was a decline in the forecasted financial performance for the
Extrusions segment (and asset group). As such, management evaluated the recoverability of the long-lived assets of the Extrusions asset group and, ultimately, determined that such assets were impaired. Accordingly, in the quarter ended
September 30, 2022, the Company recorded an impairment charge of $92, composed of $90 for Properties, plants, and equipment and $2 for intangible assets. Also, in the quarters ended December 31, 2022, September 30, 2022, and December 31,
2021, Restructuring and other charges includes $31, $15, and $11, respectively, related to the settlement of a portion of the Company’s U.S. defined benefit pension plan obligations as a result of elections by certain plan participants to
receive lump-sum benefit payments. 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 Total Company Adjusted EBITDA presented elsewhere in this Appendix). In the quarter ended September 30, 2022, Other expenses, net
includes an $11 loss for the remeasurement of monetary balances, primarily cash, related to the Company’s former operations in Russia (see Note 5) from rubles to the U.S. dollar. This loss was the result of a significant weakening of the
Russian ruble against the U.S. dollar in the period.

EBITDA Margin 7.9% 6.3% 8.0% 9.4% 8.2% 9.0% 10.4% 10.7% 7.9% 9.5% Arconic’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 footnote 4); Unrealized (gains) losses on mark-to-market hedging instruments and derivatives (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’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 first quarter of 2022, management modified the Company’s definition of Adjusted EBITDA to exclude the impact
of unrealized gains and losses on mark-to-market hedging instruments and derivatives. This modification was deemed appropriate as Arconic is considering entering into additional hedging instruments in future reporting periods if favorable
conditions exist to mitigate cost inflation. Certain of these instruments may not qualify for hedge accounting resulting in unrealized gains and losses being recorded directly to Sales or Cost of goods sold, as appropriate (i.e.,
mark-to-market). Additionally, this change was also applied to derivatives that do not qualify for hedge accounting for consistency purposes. The Company does not have a regular practice of entering into contracts that are treated as
derivatives for accounting purposes. Ultimately, this change was made to maintain the transparency and visibility of the underlying operating performance of Arconic. Prior to this change, the Company had a limited number of hedging
instruments and derivatives that did not qualify for hedge accounting, the unrealized impact of which was not material to Arconic’s Adjusted EBITDA. Accordingly, periods prior to the effective date of this change were not recast to reflect
this change. Reconciliation of Total Company Adjusted EBITDA
In the quarters ended September 30, 2022 and June 30, 2022, Other expenses (income), net includes an
$11 loss and a $54 gain, respectively, for the remeasurement of monetary balances, primarily cash, related to the Company’s operations in Russia from rubles to the U.S. dollar. This loss and gain were the result of a significant weakening and
strengthening, respectively, of the ruble against the U.S. dollar in the respective periods. In the year ended December 31, 2022, Restructuring and other charges includes a loss of $306 ($304 after-tax) (4Q22) related to the sale of the
Company’s operations in Russia and an impairment charge of $92 (3Q22) related to a business review of Arconic’s Extrusions segment (see footnote 5 to the Reconciliation of Segment Adjusted EBITDA presented elsewhere in this Appendix), as well
as a charge of $46 ($31-4Q22, $15-3Q22) related to the settlement of a portion of the Company’s U.S. defined benefit pension plan obligations as a result of elections by certain plan participants to receive lump-sum benefit payments. In the
year ended December 31, 2021, Restructuring and other charges includes $584 related to the settlement of a portion of the Company’s U.S. defined benefit pension plan obligations as a result of the purchase of a group annuity contract
($549-2Q21) and elections by certain plan participants to receive lump-sum benefit payments ($11-4Q21, $5-3Q21, $19-2Q21). See footnote 4 to the Reconciliation of Segment Adjusted EBITDA presented elsewhere in this Appendix. 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 special items include the following: • for the quarter ended December 31, 2022, a charge related to environmental
remediation matters ($9), costs related to several legal matters ($1), and other items ($4); • for the quarter ended September 30, 2022, a charge related to the Grasse River environmental remediation matter ($9), costs related to the
Grenfell Tower legal matter ($3), and other items ($(2)); • for the quarter ended June 30, 2022, costs related to a new labor agreement with the United Steelworkers ($19), a charge for two environmental remediation matters ($9), costs
related to several legal matters, including Grenfell Tower ($3) and other ($4), and other items ($4); • for the quarter ended March 31, 2022, costs related to several legal matters ($2), costs related to the packaging restart at the
Tennessee rolling mill ($2), and other items ($1); • for the quarter ended December 31, 2021, costs related to several legal matters, including Grenfell Tower ($4) and other ($2), costs related to both an equipment fire and packaging restart

Company Adjusted EBITDA presented elsewhere in this Appendix for (i) the Company’s definition of Adjusted EBITDA and (ii) management’s rationale for the presentation of this non-GAAP measure. The “As reported” column presents a reconciliation
of this non-GAAP measure to the most directly comparable GAAP measure. Adjusted EBITDA excluding Russia is also a non-GAAP financial measure. On November 15, 2022, Arconic completed the sale of 100% of its operations in Russia (see footnote
5 to the Reconciliation of Segment Adjusted EBITDA presented elsewhere in this Appendix). Accordingly, management believes the presentation of Adjusted EBITDA excluding Russia is meaningful to investors because such measure provides context
as to the contribution made by the Company’s former operations in Russia relative to Arconic’s total financial performance. Additionally, this measure provides a historical basis with which to compare the Company’s financial performance in
future periods. The “Russia” column presents the unaudited combined financial information of Arconic’s subsidiaries that held the Company’s former operations in Russia prepared from the historical accounting records of these legal entities.
This information is not equivalent to that which would be presented as consolidated financial information prepared in accordance with accounting principles generally accepted in the United States of America if these subsidiaries were to be
presented as a standalone consolidated reporting entity. Other amounts related to Arconic’s former operations in Russia recorded in the historical accounting records of other legal entities included in the Company’s consolidated group, such
as the loss on the sale of the previously mentioned former subsidiaries recorded by the direct parent company of these legal entities, were presented in the “As recast” column. However, the amount presented as Adjusted EBITDA excluding Russia
is the same whether these other amounts related to Arconic’s former operations in Russia are presented in the “Russia” column or the “As recast” column. The amounts in the “As recast” column are equal to the amounts in the “As reported”
column less the amounts in the “Russia” column. Consequently, there are limitations in the usefulness of the amounts presented in the “As recast” column for Net (loss) income attributable to Arconic Corporation and (Benefit) Provision for
income taxes. For example, the (Benefit) Provision for income taxes would need to be recalculated on a “without” approach to consider the consolidated company excluding the former operations in Russia, the impact of which may extend beyond
subtracting the amount for (Benefit) Provision for income taxes presented in the “Russia” column from the consolidated amount in the “As reported” column. Conversely, the amount presented for Adjusted EBITDA excluding Russia does not contain
any such limitations. See footnote 1 to the Reconciliation of Total Company Adjusted EBITDA presented elsewhere in this Appendix. See footnote 2 to the Reconciliation of Total Company Adjusted EBITDA presented elsewhere in this
Appendix. See footnote 4 to the Reconciliation of Total Company Adjusted EBITDA presented elsewhere in this Appendix. See footnote 5 to the Reconciliation of Total Company Adjusted EBITDA presented elsewhere in this Appendix. See footnote

EBITDA, (ii) management’s rationale for the presentation of this non-GAAP measure, and (iii) a reconciliation of this non-GAAP measure to the most directly comparable GAAP measure. Arconic’s definition of working capital is Receivables plus
Inventories less Accounts payable, trade. In January 2021, the Company contributed a total of $200 to its two funded U.S. defined benefit pension plans, comprised of the estimated minimum required funding for 2021 of $183 and an additional
$17. In April 2021, the Company contributed a total of $250 to its two funded U.S. defined benefit pension plans to maintain the funding level of the remaining plan obligations not transferred under a group annuity contract. Other includes
the impact of metal price lag as follows: 4Q22-$8; 3Q22-$15; 2Q22-$30; 1Q22-$(36); 4Q21-$11; 3Q21-$(21); 2Q21-$(11); and 1Q21-$5. See footnote 4 in Reconciliation of Total Company Adjusted EBITDA presented elsewhere in this Appendix for
additional information on metal price lag. Arconic’s definition of Free Cash Flow is Cash from operations less capital expenditures. Free Cash Flow is a non-GAAP financial measure. Management believes that this measure is meaningful to
investors because management reviews cash flows generated from operations after taking into consideration capital expenditures, which are both necessary to maintain and expand the Company’s asset base and expected to generate future cash
flows from operations. It is important to note that Free Cash Flow does not represent the residual cash flow available for discretionary expenditures since other non-discretionary expenditures, such as mandatory debt service requirements, are
not deducted from the measure. 4Q22: Cash provided from operations of $188 less capital expenditures of $70 = free cash flow of $118 3Q22: Cash provided from operations of $91 less capital expenditures of $47 = free cash flow of $44 2Q22:
Cash provided from operations of $162 less capital expenditures of $33 = free cash flow of $129 1Q22: Cash used for operations of $(103) less capital expenditures of $95 = free cash flow of $(198) 4Q21: Cash provided from operations of $96
