There were 56,000, 43,000 and 1,000 anti-dilutive stock awards for the years ended December 31, 2025, 2024 and 2023.
Basic earnings per share was computed by dividing the earnings attributable to the common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share was computed by dividing earnings attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period, including potentially dilutive shares of common stock for the period determined using the treasury stock method.

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.
