Earnings Per Share

3 Months Ended

Mar. 31, 2022

Basic earnings per share (EPS) amounts are computed by dividing Net income attributable to Arconic by the weighted-average number of common shares outstanding. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive share equivalents outstanding. Specific to Arconic, such share equivalents consist of outstanding employee stock awards (excluding out-of-the-money stock options – see below). For periods in which the Company generates net income, the diluted weighted-average number of shares include common share equivalents associated with outstanding employee stock awards. For periods in which the Company generates a net loss, common share equivalents are excluded from the diluted weighted-average number of shares as their effect is anti-dilutive.

The share information used to compute basic and diluted EPS attributable to Arconic common stockholders was as follows (shares in millions):

* Stock options are in-the-money when the respective exercise price of each such option is less than the average market price of the Company’s common stock during the applicable period presented. Conversely, stock options are out-of-the-money when the respective exercise price of each such option is more than the average market price of the Company’s common stock during the applicable period presented. Out-of-the-money stock options never result in common share equivalents for purposes of diluted EPS regardless of whether a company generates net income or a net loss. As of March 31, 2022 and March 31, 2021, there were 0.3 million and 0.4 million, respectively, out-of-the-money stock options outstanding with a weighted-average exercise price of $31.48 and $31.41, respectively.
