Important Information about the Reverse Stock Split Proposal

This communication may be deemed to be solicitation material in connection with the proposal to be submitted to Alcoa’s shareholders at its special meeting seeking approval to effect a reverse stock split and a reduction in the number of authorized shares of its common stock (the “Reverse Split Proposal”). In connection with the Reverse Split Proposal, Alcoa has filed a preliminary proxy statement on Schedule 14A with the U.S. Securities and Exchange Commission (the “SEC”). Shareholders are urged to read the preliminary proxy

statement and all other relevant documents filed with the SEC when they become available, including the definitive proxy statement, because they will contain important information about the Reverse Split Proposal.

Investors and security holders will be able to obtain the documents (when available) free of charge at the SEC’s website, www.sec.gov. In addition, shareholders may obtain free copies of the documents filed with the SEC when available at Alcoa’s website, www.alcoa.com. You also may read and copy any reports, statements and other information filed by Alcoa with the SEC at the SEC public reference room at 100 F Street, N.E. Room 1580, Washington, D.C. 20549. Please call the SEC at 1-800-SEC-0330 or visit the

SEC’s website for further information on its public reference room.

Participants in the Solicitation

Alcoa and its directors and executive officers may be deemed to be participants in the solicitation of proxies from Alcoa’s shareholders in respect of the Reverse Split Proposal. Information about the directors and executive officers of Alcoa is set forth in Alcoa’s proxy statement for its 2016 Annual Meeting of Shareholders, which was filed with the SEC on March 24, 2016. Investors may obtain additional information regarding the interests of Alcoa and its directors and executive officers in the Reverse Split Proposal by reading the preliminary proxy statement and, when it becomes available, the definitive proxy statement relating to the special meeting.

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,” “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, statements about the reverse stock split, authorized share count reduction and special meeting. 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) the possibility that shareholder approval for the reverse stock split and authorized share count reduction will not be obtained; (d) the possibility that factors unrelated to the reverse stock split may impact the per share trading price of Alcoa’s common stock; and (e) the other risk factors discussed in Alcoa’s Form 10-K for the year ended December 31, 2015, and other reports filed with the 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.
