On May 10, 2017, Alcoa Corporation (“Alcoa” or the “Company”) held its 2017 Annual Meeting of Stockholders (the “Annual Meeting”). At the Annual Meeting, Alcoa’s stockholders approved the Alcoa Corporation Annual Cash Incentive Compensation Plan (Amended and Restated as of May 10, 2017) (the “Cash Incentive Plan”), including the material terms of the Cash Incentive Plan under Section 162(m) of the Internal Revenue Code of 1986, as amended (“Section 162(m)”).

The Cash Incentive Plan is designed to provide annual cash incentive compensation, including performance-based cash compensation that is fully deductible by Alcoa for federal income tax purposes under Section 162(m), to Alcoa’s executives and other key employees. The Cash Incentive Plan was amended principally to (a) expand Alcoa’s ability to “clawback” or recoup previously granted awards and require participants to acknowledge that they will cooperate with Alcoa in connection with the recoupment of such awards, (b) broaden the authority of the Compensation and Benefits Committee (the “Committee”) of the Alcoa Board of Directors (the “Board”) to impose additional restrictions and adjust awards in connection with determining award payouts, unless not permitted by Section 162(m), and (c) make certain other definitional, accounting, conforming and non-substantive changes. It is not possible to determine the specific amounts that may be awarded or payable under the Cash Incentive Plan after the Annual Meeting because the grant and payment of awards are subject to the discretion of the Committee. The summary of the Cash Incentive Plan is qualified in its entirety by reference to the full text of the Cash Incentive Plan, which is attached hereto as Exhibit 99.1 and incorporated herein by reference.

Also at the Annual Meeting, Alcoa’s stockholders approved the Alcoa Corporation 2016 Stock Incentive Plan (Amended and Restated as of May 10, 2017) (the “Equity Plan”), including the material terms of the Equity Plan under Section 162(m).

The Equity Plan is a long-term incentive plan pursuant to which awards may be granted to directors, officers and other employees of Alcoa and its subsidiaries, including option rights, stock appreciation rights, restricted stock, restricted stock units, performance awards, and other awards. The Equity Plan was amended principally to (a) preserve and extend Alcoa’s ability to deduct “qualified performance-based compensation” granted to certain of its executive officers, without regard to the limitation imposed by Section 162(m), (b) increase the total number of shares authorized for issuance from 19,000,000 to 30,000,000, (c) include additional restrictions on share recycling to prohibit the adding back to the pool of shares under the Equity Plan those shares used in payment of the base price of stock appreciation rights (“SARs”), (d) include a new minimum one-year vesting schedule for stock options and SARs, (e) prohibit the paying of dividends on stock options or SARs, (f) expand Alcoa’s ability to “clawback” or recoup previously granted awards and require participants to acknowledge that they will cooperate with Alcoa in connection with the recoupment of such awards, (g) assign a modified ratio for counting usage of shares upon issuance of full-value awards (restricted stock and restricted stock units) of 1.63 to one share for awards granted on and after the Annual Meeting, and (h) make certain other clarifying, conforming and non-substantive changes. It is not possible to determine specific amounts and types of awards that may be granted under the Equity Plan after the Annual Meeting because the grant and payment of such awards will be subject to the discretion of the Committee. The summary of the Equity Plan is qualified in its entirety by reference to the full text of the Equity Plan, which is attached hereto as Exhibit 99.2 and incorporated herein by reference.
