Important Information 2

Important Information (continued) 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. 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 it ems, and free cash flow) to the most directly comparable GAAP financial measures because such reconciliations, as well as the directly comparable GAAP measur es, are not available without unreasonable efforts due to the variability and complexity of the charges and other components excluded from the non - GAAP measur es, such as the effects of foreign currency movements, gains or losses on sales of assets, taxes, and any future restructuring or impairment charges. Th ese 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. How met Aerospace believes such reconciliations of forward - looking non - GAAP financial measures would imply a degree of precision that would be confusing or misl eading to investors. References to “Pro Forma” reflect metrics further adjusted for separation - related allocations, as if the Arconic Inc. separation transaction (effective as of 4/1/2020) had occurred at the beginning of the period presented. 3

Management 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, Discrete tax items, and Other special items (co llectively, “Special items”). In addition, management believes that the Income from continuing operations excluding Special items and Allocation adjustments and Diluted EPS excluding Special items and All oca tion adjustments are meaningful to investors as it reflects how management reviewed the standalone costs of Howmet in the quarter ended March 31, 2020 as if the Arconic Inc. Separation Transaction had happened on January 1, 2020. 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 Income from continuing operations determined under GAAP as well as Income from continuing operations excluding Special items. (1) Discrete tax items for each period are discussed further on the Reconciliation of the Operational Tax Rate. (2) 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) 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. Separation Transaction had occurred on Januar y 1 , 2020.

Reconciliation of 2021 Adjusted Free Cash Flow ($ in millions) FY 2021 Cash provided from operations $449 Cash receipts from sold receivables 267 Capital expenditures (199) Adjusted free cash flow (1) $517 The net cash funding from the sale of accounts receivables was neither a use of cash nor a source of cash in the period presented . In the third quarter of 2021 , the Company restructured its accounts receivable securitization . As a result, going forward, Cash receipts from sold receivables (which had been included in the investing section of the Statement of Consolidated Cash Flows) will be $ 0 as the entire impact of the accounts receivable securitization program will be included in the Cash provided from operations section of the Statement of Consolidated Cash Flows . Consequently, for the fourth quarter 2021 and full year 2022 , the definition of Adjusted free cash flow is Cash provided from operations less Capital expenditures . Adjusted free cash flow is a non - GAAP financial measure. Management believes that this measures is meaningful to investors becau se management reviews cash flows generated from operations after taking into consideration capital expenditures (due to the fact that these expenditures are considered neces sar y to maintain and expand the Company's asset base and are expected to generate future cash flows from operations), as well as cash receipts from net sales of beneficial interest in so ld receivables. It is important to note that Adjusted free cash flow does not represent the residual cash flow available for discretionary expenditures since other non - discretionary expenditures, s uch as mandatory debt service requirements, are not deducted from the measure. (1) Record since April 2020 separation; FY 2021: Cash used for financing activities = ($1,444M) and Cash provided from investing act ivities = $107M . 78

Reconciliation of 2020 Adjusted Free Cash Flow ($ in millions) FY 2020 Cash provided from operations $9 Cash receipts from sold receivables 422 Capital expenditures (267) Adjusted free cash flow (1) $ 164 Costs associated with the Arconic Inc. Separation Transaction 77 Allocation adjustments (2) 146 Adjusted free cash flow, excluding costs associated with the Arconic Inc. Separation Transaction $ 387 Adjusted free cash flow and Adjusted free cash flow, excluding costs associated with the Arconic Inc. Separation Transaction are non - GAAP financial measures. Management believes that these measures are meaningful to investor s because management reviews cash flows generated from operations after taking into consideration capital expenditures (due to the fact th at these expenditures are considered necessary to maintain and expand the Company's asset base and are expected to generate future cash flows from operations), cash receipts from net sales of beneficial interest in sold receivab les , as well as costs associated with the Arconic Inc. Separation Transaction. It is important to note that Adjusted free cash flow and Adjusted free cash flow, excluding costs associated with the Arconic Inc. Separation Transaction, measures do not represent the residual cash flow available for discretionary expenditures since ot her non - discretionary expenditures, such as mandatory debt service requirements, are not deducted from the measure. The net cash funding from the sale of accounts receivables was $329 million in the first quarter of 2020 which represented a $21 million use of cash in the first quarter. The net cash funding from the sale of accounts receivables was $299 million in the second quarter of 2020 which represented a $30 million use of cash in the second quarter. The net cash funding fr om the sale of accounts receivables was $255 million in the third quarter of 2020 which represented a $45 million use of cash in the third quarter. The net cash funding from the sale of accounts receivables was $250 million in the fourth quarter of 2020 which represented a $5 million use of cash in the fourth quarter. During the third quarter ended September 30, 2020, the Company identified a misclassification in the presentation of changes in accounts payable and capital expenditures in its previously issued Statement of Consolidated Cash Flows. Although management has determined that such misclassification did not materially misstate such prior financial statements, t he Company has revised its Statement of Consolidated Cash Flows for the twelve months ended December 31, 2019 resulting in an increase of $55 to previously reported capital expenditures within cash provided from investing activiti es with a corresponding offset in accounts payable, trade within cash used for operations. The Company also revised its Statement of Consolidated Cash Flows to increase its previously reported capital expenditures with a corresponding offset in accounts payable, trade of $74 which is reflected in the twelve months ended December 31, 2020 above. (2) Adjustments include differences between allocations as required under discontinued operations as part of generally accepted accounting pr inc iples and estimated actual spending in cash provided from operations and capital expenditures related to Howmet on a standalone basis as if the Arconic Inc. Separation Transaction had occurred on January 1, 2020. (1) 2Q 2020 – 4Q 2020 (GAAP): Cash used for financing activities = ($1,514M) and Cash provided from investing activities = $260M. FY 2020 (GAAP): Cash used for financing activities = ($369M) and Cash provided from investing activities = $271M. 79

Reconciliation of Adjusted EBITDA Excluding Special Items and Allocation Adjustments ($ in millions) FY 20 19 FY 2020 FY 2021 Income from continuing operations after income taxes $ 126 $211 $258 Add: Provision (benefit) for income taxes $ 84 $(40) $66 Other expense, net 31 74 19 Loss on debt redemption — 64 146 Interest expense 338 317 259 Restructuring and other charges 582 182 90 Provision for depreciation and amortization 2 95 279 270 Adjusted EBITDA $1 ,456 $1,087 $1,108 Add: Costs associated with the Arconic Inc.

Net margin is equivalent to Sales minus the following items: Cost of goods sold, Selling, general administrative, and other expenses, Research and develo pme nt expenses, and Provision for depreciation and amortization. Management believes that Adjusted EBITDA, Adjusted EBITDA excluding Special items and Allocation adjustments, and Adjusted EB ITD A Margin excluding Special items and Allocation adjustments are meaningful to investors because it provides additional information with respect to the Company's operating performance and th e C ompany’s ability to meet its financial obligations. The Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies. (1) Plant fire costs excludes the impacts of $6 of depreciation in the second quarter ended June 30, 2020. (2) Adjustments include differences between allocations as required under discontinued operations as part of generally accepted a cc ounting principals and estimated actual revenue and spending in selling, general administrative, depreciation, depletion, and other expenses related to Howmet on a standalone basis as if the Arconic Inc. Separation Transaction had occurred in each year on January 1, 2019 or January 1, 2020 , respectively . 80

Management believes that this measure is meaningful to investors because m anagement reviews the operating results of the Company excluding the impacts of Special items. There can be no assurances that additional Special items will not occur in future per iod s. To compensate for this limitation, management believes that it is appropriate to consider both the Effective tax rate determined under GAAP as well as the Operational tax rate.

Separation Transaction, and a $4 charge related to tax rates in various jurisdictions. The U.S. tax law change resulted from final regulations issued in July 2020 that provided an election to exclu de from global intangible low - taxed income any foreign earnings subject to a local country tax rate of at least 90% of the U.S. tax rate. 82

Management believes that this measure is meaningful to investors because management reviews the operating results of the Company excluding the impacts of Restructuring and other charges, Discrete tax items, and Other special items (collective ly, “Special items”). 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 Income from co ntinuing operations determined under GAAP as well as Income from continuing operations excluding Special items.

(2) 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. 84
