On May 14, 2019, the Board of Directors (the “Board”) of Arconic Inc. (the “Company” or “Arconic”) authorized an additional share repurchase program of up to $500 million of its outstanding common stock (the “May 2019 Share Repurchase Program”). The Board had previously authorized share repurchase programs in the aggregate of $1 billion, of which $100 million authorization remains available for repurchases through the end of 2020 (the “Prior Remaining Authorization”). Arconic completed a $700 million accelerated share repurchase (“ASR”) of approximately 36.4 million shares of its common stock in April 2019. Additionally, the Company entered into an ASR agreement on May 2, 2019 to repurchase another $200 million of its common stock and received an initial delivery of approximately 7.5 million shares; the agreement is expected to be completed during the first half of 2019.

As of the date of this report, the Company has a total of $600 million repurchase authorization remaining pursuant to the May 2019 Share Repurchase Program and the Prior Remaining Authorization. The Company currently has approximately 441 million shares of common stock outstanding.

Under its share repurchase programs, the Company may repurchase shares from time to time, in amounts, at prices, and at such times as the Company deems appropriate. Repurchases will be subject to market conditions, legal requirements and other considerations. The Company is not obligated to repurchase any specific number of shares or to do so at any particular time, and the share repurchase programs may be suspended, modified or terminated at any time without prior notice.
