Capitalized terms used and not otherwise defined herein shall have the same meaning as given in the Indenture, the 6.50% Bonds or the 6.75% Notes, as the case may be.

Forward-Looking Statements

This Current Report on Form 8-K 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,” “future,” “intends,” “may,” “outlook,” “plans,” “projects,” “seeks,” “sees,” “should,” “targets,” “will,” “would,” or other words of similar meaning. All statements that reflect the Company’s expectations, assumptions or projections about the future, other than statements of historical fact, are forward-looking statements, including, without limitation, statements regarding future expenses and tax rates. 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 the Company 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 disruptions or volatility in the global financial markets, including changes affecting U.S. Treasury securities or failure of the trustee to receive moneys from Arconic sufficient to pay the redemption price of the Notes, whether due to third-party payments system disruptions or other events and the other risk factors summarized in the Company’s Form 10-K for the year ended December 31, 2016 and other reports filed with the U.S. Securities and Exchange Commission. Arconic 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.
