Profitability metric

EPS (Earnings Per Share)

Shows the portion of company profit attributable to each weighted-average common share.

Formula

EPS = (Net Income - Preferred Dividends) / Weighted-Average Common Shares

Worked example$2 billion of attributable profit divided by 500 million shares gives EPS of $4.00.

Calculation steps

  1. Start with attributable net income of $2 billion.
  2. Use 500 million weighted-average shares.
  3. Divide $2 billion by 500 million to get $4.00 per share.

How to interpret it

Consistent EPS growth can signal improving profitability, but it should be checked against revenue and cash-flow growth.

Industry context

Share structures and normal margin levels differ widely, so EPS is most useful when compared with the same company's history and expectations.

Common mistakes

  • Do not use ending shares instead of weighted-average shares.
  • Distinguish basic EPS from diluted EPS.
  • Check whether buybacks, dilution, or one-time items drove the change.
