Earnings Per Share
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 our 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.

(1)The numerator is adjusted in the calculation of diluted earnings per share under the if-converted method to include net income attributable to the non-controlling interest calculated as its pre-tax income adjusted for a corporate effective tax rate of 26% for the years ended December 31, 2024 and 2023.
(2)Diluted earnings per share for the year ended December 31, 2025 excludes 11.2 million weighted average shares of Class B common stock as the effect would be anti-dilutive.

About Earnings Per Share Disclosures

The earnings per share disclosure breaks down the calculation from net income to both basic and diluted EPS, revealing the full impact of a company's capital structure on per-share economics. The reconciliation between basic and diluted share counts exposes how many stock options, RSUs, convertible securities, and warrants are potentially dilutive to existing shareholders.

Key signals: a widening gap between basic and diluted shares indicates growing dilution from equity compensation or convertible instruments. Anti-dilutive securities excluded from the diluted calculation deserve attention — they represent latent dilution that will materialize if the stock price rises. Watch for the effect of share buybacks on per-share metrics: EPS growth driven primarily by repurchases rather than income growth signals weakening fundamentals. Compare year-over-year changes in the diluted share count against equity compensation expense to assess whether management is effectively managing dilution.
