 Cautionary Statement 2 Alcoa Logo 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,” “estimates,” “expects,” “forecasts,” “intends,” “outlook,” “plans,” “projects,” “should,” “targets,” “will,” 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 for aluminum, aluminum end-market growth, aluminum consumption rates, or other trend projections, targeted financial results or operating performance, and statements about Alcoa’s strategies, objectives, goals, targets, outlook, and business and financial prospects. Forward-looking statements are subject to a number of known and unknown risks, uncertainties, and other factors and are not guarantees of future performance. Important factors that could cause actual results to differ materially from those 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 for primary aluminum, alumina, and other products, and fluctuations in indexed-based and spot prices for alumina; (b) unfavorable changes in general business and economic conditions, in the global financial markets, or in the markets served by Alcoa, including automotive and commercial transportation, aerospace, building and construction, distribution, packaging, consumer electronics, oil and gas, defense, and industrial gas turbines; (c) the impact of changes in foreign currency exchange rates on costs and results, particularly the Australian dollar, Brazilian real, Canadian dollar, and Euro; (d) increases in energy costs, including electricity, natural gas, and fuel oil, or the unavailability or interruption of energy supplies; (e) increases in the costs of other raw materials, including caustic soda or carbon products; (f) Alcoa’s inability to achieve the level of revenue growth, cash generation, cost savings, improvement in profitability and margins, fiscal discipline, or strengthening of operations (including moving its alumina refining and aluminum smelting businesses down on the industry cost curve and increasing revenues in its Flat-Rolled Products and Engineered Products and Solutions segments), anticipated from its productivity improvement, cash sustainability and other initiatives; (g) Alcoa's inability to realize expected benefits from newly constructed, expanded or acquired facilities or from international joint ventures as planned and by targeted completion dates, including the joint venture in Saudi Arabia or the upstream operations in Brazil; (h) 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, or other events beyond Alcoa’s control; (i) the outcome of contingencies, including legal proceedings, government investigations, and environmental remediation; (j) the business or financial condition of key customers, suppliers, and business partners; (k) changes in tax rates or benefits; and (l) the other risk factors summarized in Alcoa's Form 10-K for the year ended December 31, 2010, 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. |
