Important Information 2 [Alcoa logo] Forward-Looking Statements This communication 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,” “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, end market conditions, supply/demand balances, and growth opportunities for aluminum in automotive, aerospace, and other applications; targeted financial results or operating performance; statements about Alcoa’s strategies, outlook, and business and financial prospects; and statements regarding the acceleration of Alcoa’s portfolio transformation, including the expected benefits of acquisitions, including the completed acquisition of the Firth Rixson business and TITAL, and the pending acquisition of RTI International Metals, Inc. (RTI). These statements reflect beliefs and assumptions that are based on Alcoa’s perception of historical trends, current conditions, and expected future developments, as well as other factors management believes are appropriate in the circumstances. Forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties, and changes in circumstances that are difficult to predict. Important factors that could cause actual results to differ materially from those expressed or implied in the forward-looking statements include: (a) 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; (b) deterioration in global economic and financial market conditions generally; (c) unfavorable changes in the markets served by Alcoa, including aerospace, automotive, commercial transportation, building and construction, packaging, defense, and industrial gas turbine; (d) the impact of changes in foreign currency exchange rates on costs and results, particularly the Australian dollar, Brazilian real, Canadian dollar, euro, and Norwegian kroner; (e) increases in energy costs or the unavailability or interruption of energy supplies; (f) increases in the costs of other raw materials; (g) Alcoa’s 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 moving its alumina refining and aluminum smelting businesses down on the industry cost curves and increasing revenues and improving margins in its Global Rolled Products and Engineered Products and Solutions segments) anticipated from its restructuring programs and productivity improvement, cash sustainability, technology, and other initiatives; (h) Alcoa’s inability to realize expected benefits, in each case as planned and by targeted completion dates, from acquisitions (including achieving the expected levels of synergies, revenue growth, or EBITDA margin improvement), sales of assets, closures or curtailments of facilities, newly constructed, expanded, or acquired facilities, or international joint ventures, including the joint venture in Saudi Arabia; (i) political, economic, and regulatory risks in the countries in which Alcoa operates or sells products, including unfavorable changes in laws and governmental policies, civil unrest, imposition of sanctions, expropriation of assets, or other events beyond Alcoa’s control; (j) the outcome of contingencies, including legal proceedings, government or regulatory investigations, and environmental remediation; (k) the impact of cyber attacks and potential information technology or data security breaches; (l) failure to receive the required votes of RTI’s shareholders to approve the merger of RTI with Alcoa, or the failure to satisfy the other closing conditions to the acquisition; (m) the risk that acquisitions (including Firth Rixson, TITAL and RTI) will not be integrated successfully or such integration may be more difficult, time-consuming or costly than expected; (n) the possibility that certain assumptions with respect to RTI or the acquisition could prove to be inaccurate, including the expected timing of closing; (o) the loss of customers, suppliers and other business relationships as a result of acquisitions, competitive developments, or other factors; (p) the potential failure to retain key employees of Alcoa or acquired businesses; (q) the effect of an increased number of Alcoa shares outstanding as a result of the acquisition of RTI; (r) the impact of potential sales of Alcoa common stock issued in the RTI acquisition; (s) failure to successfully implement, to achieve commercialization of, or to realize expected benefits from, new or innovative technologies, equipment, processes, or products, including the Micromill™, innovative aluminum wheels, and advanced alloys; and (t) the other risk factors discussed in Alcoa’s Form 10-K for the year ended December 31, 2014, and other reports filed with the 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. Nothing on Alcoa’s website is included or incorporated by reference herein.

Important Information (continued) 3 [Alcoa logo] 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. Any reference to historical EBITDA means adjusted EBITDA, for which we have provided calculations and reconciliations in the Appendix. Alcoa has not provided a reconciliation of any forward-looking non-GAAP financial measure to the most directly comparable GAAP financial measure, 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.

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 income (loss) attributable to Alcoa. As a result, this revision does not impact the consolidated results of Alcoa. Segment information for all prior periods presented was revised to reflect this change.

Reconciliation of Adjusted Income 46 [Alcoa logo] (in millions, except per-share amounts) Income Diluted EPS (3) Quarter ended Quarter ended June 30, March 31, June 30, June 30, March 31, June 30, 2014 2015 2015 2014 2015 2015 Net income attributable to Alcoa $138 $195 $140 $0.12 $0.14 $0.10 Restructuring and other charges 54 158 141 Discrete tax items (1) (2) (5) Other special items (2) 26 10 (26) Net income attributable to Alcoa – as adjusted $216 $363 $250 0.18 0.28 0.19 Net income 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 attributable to Alcoa determined under GAAP as well as Net income attributable to Alcoa – as adjusted. Discrete tax items include the following: • for the quarter ended June 30, 2015, a net benefit for a number of small items; and • for the quarter ended June 30, 2014, a net benefit for a number of small items. Other special items include the following: • for the quarter ended June 30, 2015, a favorable tax impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized ($21), a gain on the sale of land ($19), costs associated with a future acquisition of an aerospace business ($5), 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 ($4), a net unfavorable change in certain mark-to-market energy derivative contracts ($3), and a write-down of inventory related to the permanent closure of a smelter in Brazil and a power station in Australia ($2); • 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 current and future acquisitions of aerospace businesses ($7), and a net favorable change in certain mark-to-market energy derivative contracts ($1); and • for the quarter ended June 30, 2014, a favorable tax impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized ($20), 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 ($24), costs associated with (i) a then-planned acquisition of an aerospace business ($11) and (ii) preparation for and ratification of a new labor agreement with the United Steelworkers ($11), a net favorable change in certain mark-to-market energy derivative contracts ($6), and an unfavorable impact related to the restart of one potline at the joint venture in Saudi Arabia that was previously shut down due to a period of pot instability ($6). The average number of shares applicable to diluted EPS for Net income attributable to Alcoa excludes certain share equivalents as their effect was anti-dilutive (see footnote 3 to the Statement of Consolidated Operations). However, certain of these share equivalents may become dilutive in the EPS calculation applicable to Net income attributable to Alcoa – as adjusted due to a larger, positive numerator. Specifically, these share equivalents were associated with mandatory convertible preferred stock for the quarter ended March 31, 2015. As a result, the average number of shares applicable to diluted EPS for Net income attributable to Alcoa – as adjusted was 1,315,558,890 for the quarter ended March 31, 2015.

Firth Rixson was integrated into Alcoa’s Engineered Products and Solutions segment. Alcoa’s primary measure of performance for its reportable segments is after-tax operating income (ATOI). As such, Alcoa estimated the ATOI, and therefore the Adjusted EBITDA, of Firth Rixson for the January 1, 2014 through November 18, 2014 timeframe using unaudited internal management financial statements of Firth Rixson. The ATOI estimate and calculation of Adjusted EBITDA for Firth Rixson does not purport to be the manner in which Firth Rixson’s prior management would have calculated Firth Rixson’s ATOI and Adjusted EBITDA. Additionally, this calculation of ATOI and Adjusted EBITDA is not intended to suggest that Firth Rixson’s prior management used ATOI or Adjusted EBITDA as a measure of Firth Rixson’s profitability. In 2014, the Adjusted EBITDA of Firth Rixson includes a negative impact of $13 due to the integration of Firth Rixson, primarily driven by the remeasurement of inventory to fair value, in accordance with purchase accounting requirements. Excluding this amount, Firth Rixson’s Adjusted EBITDA and Adjusted EBITDA Margin was $152 and 15.7%, respectively, for 2014.

Management believes that this measure is 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 Alcoa’s asset base and are 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.
