Net Income (Loss) Per Common Share

12 Months Ended

Dec. 31, 2021

Net income (loss) per common share—basic is calculated by dividing Net income (loss) by the weighted average number of shares of common stock outstanding during the period. Net income (loss) per common share—diluted assumes the conversion of all potentially dilutive securities and is calculated by dividing Net income (loss) by the sum of the weighted average number of shares of common stock, as defined above, outstanding plus potentially dilutive securities. Net income (loss) per common share—diluted considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common shares, as defined above, would have an anti-dilutive effect.

A reconciliation of Net income (loss) per common share is as follows:

The Class B common stock, $0.001 par value per share of Earthstone (the “Class B Common Stock”), has been excluded, as its conversion would eliminate noncontrolling interest and Net income attributable to noncontrolling interest of $26.0 million for the year ended December 31, 2021, Net loss attributable to noncontrolling interest of $15.9 million for the year ended December 31, 2020, and Net income attributable to noncontrolling interest of $0.9 million for the year ended December 31, 2019 would be added back to Net income (loss) attributable to Earthstone Energy, Inc. for the years then ended, having no dilutive effect on Net income (loss) per common share attributable to Earthstone Energy, Inc. For the year ended December 31, 2020, the Company excluded 1.1 million and 1.9 million shares, respectively, for the dilutive effect of restricted stock units and performance units in calculating diluted earnings per share as the effect was anti-dilutive due to the net loss incurred for the period.
