Understanding EV/Sales

Enterprise Value (EV) = Market Cap + Total Debt - Cash

Sales = Total Revenue (TTM)

EV/Sales is commonly used because:

  • It works for unprofitable companies where P/E doesn't apply
  • Revenue is harder to manipulate than earnings
  • It supports comparisons across companies at different profitability stages
  • It is frequently used for software and other revenue-growth-focused companies

Note: EV/Sales does not include margin, debt maturity, cash conversion, or growth durability by itself.

Comfort Systems USA, Inc. EV/Sales Ratio Formula & Definition

EV/Sales = Enterprise Value / Revenue (TTM)
