Earnings Per Share (EPS): Definition and Calculation

EPS measures a company's profit allocated to each outstanding share. Use diluted EPS for a conservative view when calculating valuation ratios.

Exact Formula:

Diluted EPS accounts for convertible securities, options, and warrants.

Notes

  • EPS (TTM) is commonly used for trailing valuation metrics
  • Share count changes (buybacks/issuance) affect EPS comparability
  • Quality of earnings matters - look beyond just the EPS number

Why This Matters:

EPS is the foundation for most valuation ratios like P/E. It represents the company's earning power on a per-share basis, making it easier to compare companies of different sizes and track progress over time.
