As previously announced, in connection with the planned separation of Alcoa Inc. (“Alcoa”) into two independent, publicly-traded companies, future company Arconic Inc.

A copy of the materials to be presented at the Arconic global investor webcast is attached hereto as Exhibit 99.1, and is incorporated herein by reference. These presentation materials will also be available shortly before the commencement of the webcast on www.alcoa.com. The materials furnished herein supplement the materials that Alcoa furnished in a Current Report on Form 8-K filed on October 18, 2016. In addition, page 12 of Exhibit 99.1 corrects page 31 of the 2nd quarter 2016 earnings analyst presentation, which inadvertently transposed the headings relating to automotive hoods and doors.

Important Information

Forward–Looking Statements

This presentation contains statements that relate to future events and expectations and as such constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include those containing such words as “anticipates,” “believes,” “could,” “estimates,” “expects,” “forecasts,” “guidance,” “goal,” “intends,” “may,” “outlook,” “plans,” “projects,” “seeks,” “sees,” “should,” “targets,” “will,” “would,” or other words of similar meaning. All statements that reflect Arconic’s expectations, assumptions or projections about the future, other than statements of historical fact, are forward-looking statements, including, without limitation, forecasts relating to the growth of the aerospace, automotive, commercial transportation and other end markets; statements and guidance regarding future financial results or operating performance; statements about Arconic’s strategies, outlook, business and financial prospects; statements regarding potential share gains; and statements regarding the separation. Forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties, and changes in circumstances that are difficult to predict. Although Arconic believes that the expectations reflected in any forward-looking statements are based on reasonable assumptions, it can give no assurance that these expectations will be attained and it is possible that actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks and uncertainties. Such risks and uncertainties include, but are not limited to: (a) the possibility that various closing conditions for the separation may not be satisfied; (b) the impact of the separation on the businesses of Arconic; (c) deterioration in global economic and financial market conditions generally; (d) unfavorable changes in the markets served by Alcoa; (e) the impact of changes in foreign currency exchange rates on costs and results; (f) the inability to achieve the level of revenue growth, cash generation, cost savings, improvement in profitability and margins, fiscal discipline, or strengthening of competitiveness and operations anticipated from restructuring programs and productivity improvement, cash sustainability, technology advancements, and other initiatives; (g) changes in discount rates or investment returns on pension assets; (h) Arconic’s inability to realize expected benefits, in each case as planned and by targeted completion dates, from acquisitions, divestitures, facility closures, curtailments, expansions, or joint ventures; (i) the impact of cyber attacks and potential information technology or data security breaches; (j) political, economic, and regulatory risks in the countries in which Arconic operates or sells products; (k) material adverse changes in aluminum industry conditions, including fluctuations in London Metal Exchange-based aluminum prices; (l) the outcome of contingencies, including legal proceedings, government or regulatory investigations, and environmental remediation; and (m) the other risk factors discussed in Alcoa Inc.’s Form 10-K for the year ended December 31, 2015, and other reports filed with the U.S. Securities and Exchange Commission (SEC). Alcoa Inc./Arconic Inc. disclaims any obligation to update publicly any forward-looking statements, whether in response to new information, future events or otherwise, except as required by applicable law. Market projections are subject to the risks discussed above and other risks in the market.

Important Information (continued)

Non-GAAP Financial Measures

Some of the information included in this presentation is derived from Alcoa Inc.’s consolidated financial information but is not presented in Alcoa Inc.’s financial statements prepared in accordance with accounting principles generally accepted in the United States of America (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 rationale for the use of the non-GAAP financial measures can be found in the Appendix to this presentation.

Arconic has not provided a reconciliation of the forecasted range for adjusted EBITDA margin on a segment and combined segments basis for fiscal 2016 and 2017 to the most directly comparable GAAP financial measures because Arconic is unable to quantify certain amounts that would be required to be included in the GAAP measure without unreasonable efforts and Arconic believes such reconciliations would imply a degree of precision that would be confusing or misleading to investors. In particular, reconciliation of guidance for adjusted EBITDA margin to the most directly comparable GAAP measure is not available without unreasonable efforts on a forward-looking basis due to the variability and complexity with respect to the charges and other components excluded from these non-GAAP measures, such as the effects of the Warrick cold metal plan, foreign currency movements, equity income, gains or losses on sales of assets, and taxes. These reconciling items are in addition to the inherent variability already included in the GAAP measure which includes, but is not limited to, price/mix, volume, and the impact of the impending separation of Alcoa Inc. Any reference to historical EBITDA means adjusted EBITDA, for which we have provided calculations and reconciliations in the Appendix.

Other Information

The separation of Alcoa Inc. into two standalone companies – Arconic Inc. (the new name for Alcoa Inc.) and Alcoa Corporation – is scheduled to become effective before the opening of the market on November 1, 2016. Upon separation, Arconic comprises the Engineered Products and Solutions

(EPS), Global Rolled Products (GRP) (other than the rolling mill operations in Warrick, Indiana (“Warrick”) and the 25.1% equity investment in the

Ma’aden Rolling Company in Saudi Arabia), and Transportation and Construction Solutions (TCS) segments. References in this presentation to “Combined Segments” reflect the combined performance of the EPS, GRP and TCS segments, and, where noted, do not include Warrick, which becomes a part of Alcoa Corporation upon separation. Arconic will exit the North American Packaging business at its Tennessee Operations following the expiration of the toll processing and services agreement with Alcoa Corporation.

(1) On September 29, 2016, Alcoa announced that its Board of Directors approved the completion of the Company’s separation into two standalone, publicly-traded companies. One such company will be named Arconic and will include Global Rolled Products, except for the Warrick, IN rolling operations and the equity interest in the rolling mill at the joint venture in Saudi Arabia, which will be included in the other company, Alcoa Corporation. Historical amounts have been adjusted to reflect this presentation.

Alcoa’s definition of Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) is net margin plus an add-back for depreciation, depletion, and amortization. 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, depletion, and amortization. The Other line in the table above includes gains/losses on asset sales and other non-operating items. 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 Alcoa’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.
