Important Information

Forward-Looking Statements

2

Certain statements in this presentation, including statements regarding the proposed acquisition of RTI by Alcoa, the expected timing, closing and benefits of the 

transaction, the expected synergies, the expected contribution of RTI to Alcoa’s revenues and profitability, the expected acceleration of Alcoa’s portfolio 

transformation, the expected size, scope and growth of the combined company’s operations and the markets in which it will operate, including the aerospace 

market, the anticipated issuance of Alcoa common stock in exchange for RTI stock in the transaction, as well as Alcoa’s plans, objectives, strategy, and intentions, 

may contain words such as: “anticipates,” “believes,” “could,” “estimates,” “expects,” “forecasts,” “intends,” “may,” “outlook,” “plans,” “projects,” “seeks,” “sees,” 

“should,” “targets,” “will,” or other words of similar meaning that constitute forward-looking statements within the meaning of the Private Securities Litigation Reform 

Act of 1995. These statements are based on Alcoa’s current expectations, estimates, forecasts and projections about the proposed transaction and the operating 

environment, economies and markets in which Alcoa and RTI operate. In making these statements, Alcoa has made assumptions with respect to: the ability of 

Alcoa and RTI to achieve expected synergies and the timing of same; the ability of Alcoa and RTI to predict and adapt to changing customer requirements, 

demand, and preferences; future capital expenditures, including the amount and nature thereof; trends and developments in the aerospace, metals engineering 

(including aluminum and titanium), advanced manufacturing, and other sectors of the economy that are related to these sectors; business strategy and outlook; 

expansion and growth of business and operations; credit risks; future results being similar to historical results; expectations related to future general economic and 

market conditions; and other matters, many of which are beyond Alcoa’s control. Alcoa’s beliefs and assumptions are inherently subject to significant business, 

economic, competitive and other uncertainties and contingencies regarding future events and as such, are subject to change and may prove to be inaccurate.  

Actual results or events could differ materially from those contemplated in forward-looking statements as a result of numerous risks and uncertainties, including: (a) 

the risk that the businesses will not be integrated successfully or such integration 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; (b) the effect of an increased number of Alcoa shares outstanding as a result of the proposed transaction; (c) the possibility that certain 

assumptions with respect to RTI or the proposed transaction could prove to be inaccurate; (d) failure to receive the required votes of RTI’s shareholders to approve 

the transaction; (e) failure to receive, delays in the receipt of, or unacceptable or burdensome conditions imposed in connection with, all required regulatory 

approvals of the proposed transaction, or the failure to satisfy the other closing conditions to the proposed transaction; (f) the potential failure to retain key 

employees of Alcoa or RTI as a result of the proposed transaction or during integration of the businesses; (g) potential sales of Alcoa common stock issued in the 

acquisition; (h) the potential loss of customers, suppliers, and other business relationships of Alcoa or RTI as a result of the transaction; (i) consequences of 

investigations by governmental agencies or regulatory authorities; (j) the failure to capitalize on anticipated growth in the commercial aerospace market; and (k) the 

other risk factors summarized in Alcoa’s Form 10-K for the year ended December 31, 2014, and other reports filed with the Securities and Exchange Commission. 

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.
