Earnings Per Share
Basic earnings per share is calculated as Net income attributable to HF Sinclair stockholders, adjusted for participating securities’ share in earnings divided by the weighted-average number of shares of common stock outstanding. Diluted earnings per share reflects the dilutive effect of the incremental shares resulting from certain share-based awards. Anti-dilutive shares were immaterial for all periods presented.

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.
