Important Information (continued) 3 Non - GAAP Financial Measures Some of the information included in this presentation is derived from Howmet Aerospace's consolidated financial information b ut is not presented in Howmet Aerospace's financial statements prepared in accordance with accounting principles generally accepted in the United States of Am erica (GAAP). Certain of these data 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 the GAAP measure. Reconciliations to the most directly comparable GAAP financial measures and management's rat ionale for the use of the non - GAAP financial measures can be found in the Appendix to this presentation. Non - GAAP financial measures in this presentation show n as Adjusted exclude special items. Howmet Aerospace has not provided reconciliations of any forward - looking non - GAAP financial measures (including Adjusted EBITDA, Adjusted EBITDA margin and Adjusted Earnings per Share, each excluding special items, Free Cash Flow and Free Cash Flow Conversion) to the most directly co mparable GAAP financial measures because such reconciliations, as well as the directly comparable GAAP measures, are not available without unreasonable effort s d ue to the variability and complexity of the charges and other components excluded from the non - GAAP measures, such as 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 , w hich includes, but is not limited to, price/mix and volume. Howmet Aerospace believes such reconciliations of forward - looking non - GAAP financial measures would imply a degree of precision that would be confusing or misleading to investors.

Man agement believes that these measures are meaningful to investors because management reviews the operating results of the Company excluding the impacts of Restructuring and other charges, Dis cre te tax items, and Other special items (collectively, "Special items"). There can be no assurances that additional Special items will not occur in future periods. To compensate for this limitation, manag eme nt believes that it is appropriate to consider both Income from continuing operations / Net income determined under GAAP as well as Income from continuing operations excluding Special items / Net income excluding Special items . (1) Income from continuing operations after income taxes was used in the FY 2020 calculation as a result of the Arconic Inc. Separation Transaction. (2) Discrete tax items for each period are discussed further on the Reconciliation of the Operational Tax Rate. (3) The tax impact on Special items is based on the applicable statutory rates whereby the difference between such rates and the Com pany's consolidated estimated annual effective tax rate is itself a Special item. (4) Adjustments include differences between allocations as required under discontinued operations as part of generally accepted a cco unting principals and estimated actual spending in selling, general administrative, and other expense s , and miscellaneous non - operating income related to pension, other post retirement benefits, and foreign exchange related to Howmet on a standalone basis as if the Arconic Inc.

Management believes that these measures are meaningful to investors because they provide additional information with respect to the Company'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. The Company's definition of Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) is net margin plus an add - back for deprecia tion and amortization.

Separation Transaction and including pre - separation allocations, Adjusted FCF pro forma for separation, and Adjusted FCF a nd allocation adjustments for the separation conversion as a percentage of Income from continuing operations excluding Special items / Net income excluding Special items are non - GAAP financ ial measures. Management believes that these measures are meaningful to investors because management reviews cash flows gener ate d from operations after taking into consideration capital expenditures (due to the fact that these expenditures are considered nec essary to maintain and expand the Company's asset base and are expected to generate future cash flows from operations), cash rec eipts from net sales of beneficial interest in sold receivables, as well as costs associated with the Arconic Inc. Separation Transaction. It is important to note that Adjusted FCF; Adjusted FCF excluding costs associated with the Arconic Inc. Separation Transaction; and Adjusted FCF excluding costs associated with the Arconic Inc. Separation Transaction and including pre - separation allocations, and Adjusted FCF pro forma for separation measures do 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. Income from continuing operations excluding Special items / Net income excluding Special items and Income from continuing ope rat ions excluding Special items and Allocation adjustments are non - GAAP financial measures. Management believes that these measures are meaningful to investors because management reviews the operating results of the Company excluding the impacts of Restructurin g a nd other charges, Discrete tax items, and Other special items (collectively, "Special items"). There can be no assurances tha t a dditional special items will not occur in future periods. To compensate for this limitation, management believes that it is appropriate to consider both Income from continuing operations after taxes / Net income determined under GAAP as well as Income from continu in g operations excluding Special items / Net income excluding Special items. In addition, management believes that these measures are meaningful to investors as they reflect how management reviewed the sta ndalone costs of Howmet in the quarter ended Mar 31, 2020 as if the Arconic Inc. Separation Transaction had happened on Jan 1, 2020. (4) Discrete tax items for the year ended December 31, 2020 included a benefit related to the release of a reserve as a result of a favorable Spanish tax case decision ($64), a benefit related to the recognition of a previously uncertain U.S. tax position ($30), a benefit for a U.S. tax law change ($30), and a net benefit for a number of small tax items ($3), partially offset by charges res ulting from the remeasurement of deferred tax balances in various jurisdictions as a result of the Arconic Inc. Separation Transactions $8, and a charge related to tax rate changes in various jurisdictions $4. (2) Adjustments include differences between allocations as required under discontinued operations as part of generally accepted a cco unting principles and estimated actual spending in selling, general, administrative, and other expenses and miscellaneous non - operating income related to pension, other post retirement benefits, and foreign exchange related to Howmet on a standalone basis as if the Arconic Inc. Separation Transaction had occurred on January 1, 2020. (6) The tax impact on Special items is based on the applicable statutory rates whereby the difference between such rates and the Com pany's consolidated estimated annual effective tax rate is itself a special item. (3) Income from continuing operations after income taxes was used in the FY 2020 calculation as a result of the Arconic Inc. Separation Transaction. (5) Other special items are included on the Reconciliation of Income from Continuing Operations / Net Income Excluding Special Items slide. (1) In the third quarter of 2021, the Company restructured its accounts receivable securitization. As a result, Cash receipts fro m s old receivables (which had been included in the investing section of the Statement of Consolidated Cash Flows) is $0 as the e nti re impact will be included in the operating section of the Statement of Consolidated Cash Flows. Consequently, for the fourth qu art er of 2021 and going forward, the definition of FCF is Cash provided from operations less Capital expenditures.

69 Reconciliation of 2022 – 2025 Adjusted Free Cash Flow Conversion FY 2025 FY 2024 FY 2023 FY 2022 ($ in millions) $1,884 $1,298 $901 $733 Cash provided from operations (453) (321) (219) (193) Capital expenditures $1,431 $977 $682 $540 Free cash flow ("FCF") (a) $1,508 $1,155 $765 $469 Net Income (b) Special items: 84 21 23 56 Restructuring and other charges (52) (59) (9) (8) Discrete tax items 18 (11) (13) 103 Other special items (1) (25) 1 — (27) Tax impact (2) $1,533 $1,107 $766 $593 Net income excluding Special items (c) 95% 85% 89% 115% FCF conversion as a percentage of Net income (a)/(b) 93% 88% 89% 91% FCF conversion as a percentage of Net income excluding Special items (a)/(c) $8,252 $7,430 $6,640 $5,663 Sales (d) 17.3% 13.1% 10.3% 9.5% FCF % of Revenue (a)/(d) FCF , FCF conversion as a percentage of Net income excluding Special items, and FCF % of Revenue are non - GAAP financial measures. Management believes that these measures are meaningful to investors because management reviews cash flows generated from operations after taking into consideration capital expenditures (due to the fact that these expenditures are considered necessary to maintain and expand the Company's asset base and are expected to generate future cash flows from operations) and cash receipts from net sales of ben eficial interest in sold receivables. It is important to note that FCF do es not represent the residual cash flow available for discretionary expenditures since other non - discretionary expenditures, such as ma ndatory debt service requirements, are not deducted from the measure. (2) The tax impact on Special items is based on the applicable statutory rates whereby the difference between such rates and the Co mpany's consolidated estimated annual effective tax rate is itself a Special item. (1) Other special items are included on the Reconciliation of Income from Continuing Operations / Net Income Excluding Special Items slide. Net income excluding Special items is a non - GAAP financial measure. Management believes that this measure is meaningful to inves tors because management reviews the operating results of the Company excluding the impacts of Restructuring and other charges, Discrete tax items, and Other special items (collectively, "Special it ems"). There can be no assurances that additional Special items will not occur in future periods. To compensate for this limitation, management believes that it is appropriate to consider both Net income det erm ined under GAAP as well as Net income excluding Special items.

71 Reconciliation of Net Debt to Adjusted EBITDA Excluding Special Items Trailing - 12 months ended ($ in millions) December 31, 2025 December 31, 2020 $1,508 $211 Income from continuing operations after income taxes / Net income (1) Add: 332 (40) (Benefit) p rovision for income taxes 40 74 Other expense, net 15 64 Loss on debt redemption 151 317 Interest expense, net 84 182 Restructuring and other charges 283 279 Provision for depreciation and amortization $2,413 $1,087 Adjusted EBITDA Add: — 7 Costs associated with the Arconic Inc.

The Company's definition of Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) is net margin plus an add - back for deprecia tion and amortization. Net margin is equivalent to Sales minus the following items: Cost of goods sold; Selling, general administrative, and other expenses; Resea rch and development expenses; and Provision for depreciation and amortization. The Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies. Management believes that these measures are meaningful to investors because management assesses the Company's leverage positi on after factoring in cash that could be used to repay outstanding debt, and also because they provide additional information with respect to the Company's o per ating performance and the Company's ability to meet its financial obligations. (1) Income from continuing operations after income taxes was used in the FY 2020 calculation as a result of the Arconic Inc. Separation Transaction. (2) Plant fire costs excludes the impacts of $6 of depreciation in the second quarter of 2020.
