Earnings per Share

3 Months Ended

Mar. 31, 2024

Basic earnings per share of Class A common stock is calculated by dividing the net income attributable to Cactus Inc. during the period by the weighted average number of shares of Class A common stock outstanding during the same period. Diluted earnings per share of Class A common stock is calculated by dividing the net income attributable to Cactus Inc. during that period by the weighted average number of common shares outstanding assuming all potentially dilutive shares were issued.

We use the if-converted method to determine the potential dilutive effect of outstanding CC Units and corresponding shares of outstanding Class B common stock. We use the treasury stock method to determine the potential dilutive effect of unvested stock-based compensation awards assuming that the proceeds will be used to purchase shares of Class A common stock. For our unvested performance stock units, we first apply the criteria for contingently issuable shares before determining the potential dilutive effect using the treasury stock method.

The following table summarizes the basic and diluted earnings per share calculations:
