[Alcoa logo] Important Information 2 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,” “goal,” “intends,” “may,” “outlook,” “plans,” “projects,” “seeks,” “sees,” “should,” “targets,” “will,” “would,” or other words of similar meaning. All statements that reflect Alcoa’s expectations, assumptions or projections about the future, other than statements of historical fact, are forward-looking statements, including, without limitation, forecasts concerning global demand growth for aluminum, supply/demand balances, and growth of the aerospace, automotive, and other end markets; statements regarding targeted financial results or operating performance; statements about Alcoa’s strategies, outlook, business and financial prospects; and statements regarding the separation transaction, including the future performance of Value-Add Company and Upstream Company if the separation is completed, the expected benefits of the separation, and the expected timing of the Form 10 filing and the completion of 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 Alcoa 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) uncertainties as to the timing of the separation and whether it will be completed; (b) the possibility that various closing conditions for the separation may not be satisfied; (c) failure of the separation to qualify for the expected tax treatment; (d) the possibility that any third-party consents required in connection with the separation will not be received; (e) the impact of the separation on the businesses of Alcoa; (f) the risk that the businesses will not be separated successfully or such separation may be more difficult, time-consuming or costly than expected, which could result in additional demands on Alcoa’s resources, systems, procedures and controls, disruption of its ongoing business and diversion of management’s attention from other business concerns; (g) material adverse changes in aluminum industry conditions, including global supply and demand conditions and fluctuations in London Metal Exchange-based prices and premiums, as applicable, for primary aluminum, alumina, and other products, and fluctuations in indexed-based and spot prices for alumina;; (h) deterioration in global economic and financial market conditions generally; (i) unfavorable changes in the markets served by Alcoa; (j) the impact of changes in foreign currency exchange rates on costs and results; (k) increases in energy costs; (l) 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 (including executing on the business improvement plans, moving the Upstream alumina and aluminum businesses down on the industry cost curves, and increasing revenues and improving margins in the Value-Add businesses) anticipated from restructuring programs and productivity improvement, cash sustainability, technology advancements (including, without limitation, advanced aluminum alloys, Alcoa Micromill, and other materials and processes), and other initiatives; (m) Alcoa’s inability to realize expected benefits, in each case as planned and by targeted completion dates, from acquisitions, divestitures, facility closures, curtailments, or expansions, or international joint ventures; (n) political, economic, and regulatory risks in the countries in which Alcoa operates or sells products; (o) the outcome of contingencies, including legal proceedings, government or regulatory investigations, and environmental remediation; (p) the impact of cyber attacks and potential information technology or data security breaches; (q) the potential failure to retain key employees while the separation transaction is pending or after it is completed; (r) the risk that increased debt levels, deterioration in debt protection metrics, contraction in liquidity, or other factors could adversely affect the targeted credit ratings for Value-Add Company or Upstream Company; and (s) the other risk factors discussed in Alcoa’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 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. [Alcoa logo]

[Alcoa logo] Important Information (continued) 3 Non-GAAP Financial Measures Some of the information included in this presentation is derived from Alcoa’s consolidated financial information but is not presented in Alcoa’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. Alcoa has not provided a reconciliation of any forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures, due primarily to variability and difficulty in making accurate forecasts and projections, as not all of the information necessary for a quantitative reconciliation is available to Alcoa without unreasonable effort. Any reference to historical EBITDA means adjusted EBITDA, for which we have provided calculations and reconciliations in the Appendix.

A portion of this realignment consisted of moving the Latin American extrusions business from Corporate into a new Transportation and Construction Solutions segment (see the Reconciliation of Transportation and Construction Solutions Adjusted EBITDA for additional information). Segment information for all prior periods presented was revised to reflect the new segment structure. (2) Effective in the second quarter of 2015, management removed the impact of metal price lag from the results of the Global Rolled Products and Engineered Products and Solutions (now Engineered Products and Solutions and Transportation and Construction Solutions – see footnote 1 above) segments in order to enhance the visibility of the underlying operating performance of these businesses. Metal price lag describes the timing difference created when the average price of metal sold differs from the average cost of the metal when purchased by the respective segment. The impact of metal price lag is now reported as a separate line item in Alcoa’s reconciliation of total segment ATOI to consolidated net (loss) income attributable to Alcoa. As a result, this change does not impact the consolidated results of Alcoa. Segment information for all prior periods presented was updated to reflect this change. (3) Special items are defined as restructuring and other charges, discrete tax items, and other special items. See the Reconciliation of Adjusted Income for additional information. NOTES FOR CORPORATE AMOUNTS: LIFO and Metal price lag – these items tend to offset each other over time as the same underlying market conditions typically drive both amounts. Noncontrolling interests – primarily represents Alumina Limited’s 40% share of the operating results of the Alcoa World Alumina and Chemicals joint venture, which principally comprises Alcoa’s Alumina segment. Corporate expense – represents general and administrative expenses attributable to Alcoa’s corporate and business support locations, as well as costs associated with Alcoa’s corporate research and development center. Other – includes all other income and expenses not included in the segments, primarily: postretirement benefits and environmental remediation costs associated with certain closed or divested businesses; various corporate eliminations of inter-segment transactions; certain corporate foreign currency gains and losses; and the impact of the difference between the income tax rates applicable to the segments and the consolidated effective tax rate of the Company.

[Alcoa logo] Reconciliation of Adjusted Income (Loss) (in millions, except per-share amounts) Income (Loss) Diluted EPS (3) Quarter ended Quarter ended March 31, December 31, March 31, March 31, December 31, March 31, 2015 2015 2016 2015 2015 2016 Net income (loss) attributable to Alcoa $195 $(701) $16 $0.14 $(0.55) $0.00 Restructuring and other charges 158 507 61 Discrete tax items (1) – 187 2 Other special items (2) 10 72 29 Net income attributable to Alcoa – as adjusted $363 $65 $108 0.28 0.04 0.07 Net income (loss) attributable to Alcoa – as adjusted is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management reviews the operating results of Alcoa excluding the impacts of restructuring and other charges, discrete 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, management believes that it is appropriate to consider both Net income (loss) attributable to Alcoa determined under GAAP as well as Net income attributable to Alcoa – as adjusted. (1) Discrete tax items include the following: • for the quarter ended March 31, 2016, a net charge for a number of small items; and • for the quarter ended December 31, 2015, a charge for valuation allowances related to certain U.S. and Iceland deferred tax assets ($190) and a net benefit for a small number of items ($3). (2) Other special items include the following: • for the quarter ended March 31, 2016, costs associated with the planned separation of Alcoa ($17), an unfavorable tax impact resulting from the difference between Alcoa’s consolidated estimated annual effective tax rate and the statutory rates applicable to special items ($8), an unfavorable tax impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized ($2), and a write-down on inventory related to the permanent closure of the Warrick smelter ($2); • for the quarter ended December 31, 2015, a write-down of inventory related to the permanent closure or temporary curtailment of various facilities in Suriname and the United States ($28), an impairment of goodwill related to the soft alloy extrusion business in Brazil ($25), costs associated with the planned separation of Alcoa ($12), a net unfavorable change in certain mark-to-market energy derivative contracts ($5), and an unfavorable tax impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized ($2); and • for the quarter ended March 31, 2015, an unfavorable tax impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized ($35), a favorable tax impact resulting from the difference between Alcoa’s consolidated estimated annual effective tax rate and the statutory rates applicable to special items ($31), costs associated with acquisitions of aerospace businesses ($7), and a net favorable change in certain mark-to-market energy derivative contracts ($1). (3) The average number of shares applicable to diluted EPS for Net income (loss) attributable to Alcoa common shareholders excludes certain share equivalents as their effect was anti-dilutive. However, certain of these share equivalents may become dilutive in the EPS calculation applicable to Net income attributable to Alcoa common shareholders – as adjusted due to a larger and/or positive numerator. Specifically: • for the quarter ended March 31, 2016, share equivalents associated with outstanding employee stock options and awards were dilutive based on Net income attributable to Alcoa common shareholders – as adjusted, resulting in a diluted average number of shares of • 1,324,558,308; • for the quarter ended December 31, 2015, share equivalents associated with outstanding employee stock options and awards were dilutive based on Net income attributable to Alcoa common shareholders – as adjusted, resulting in a diluted average number of shares of 1,324,378,133; and • for the quarter ended March 30, 2015, share equivalents associated with mandatory convertible preferred were diluted based on Net Income attributable to Alcoa common shareholders – as adjusted, resulting in a diluted average number of shares of 1,315,558,890. Additionally, the subtraction of preferred stock dividends declared from the numerator (see footnote 1 to the Statement of Consolidated Operations) needs to be reversed since the related mandatory convertible preferred stock was dilutive in the EPS calculation for Net income attributable to Alcoa – as adjusted. 45

Additionally, this calculation of Adjusted EBITDA is not intended to suggest that RTI’s former management used Adjusted EBITDA as a measure of RTI’s profitability. The amounts used in these calculations were obtained from RTI’s Annual Report on Form 10-K for the year ended December 31, 2014 and Quarterly Report on Form 10-Q for the three months ended March 31, 2015 filed with the U.S. Securities and Exchange Commission on February 26, 2015 and April 30, 2015, respectively. 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.
