contained in documents filed earlier with the SEC or contained in this Registration Statement. Alcoa incorporates by reference in this Registration Statement the documents listed below and any future filings that it or the Plans may make with the
SEC under Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934 until all of the securities that may be offered by this Registration Statement are sold, except that Alcoa is not incorporating by reference any information that is
deemed to have been furnished and not filed in accordance with SEC rules.
