What drives the result

Contribution covers fixed costs first, then becomes profit. Cash - not accounting profit - pays bills, so OCF and FCF sit beside every margin. Multiples and DCF translate those cash streams into what a buyer should pay.

Recommendations

  • •Compare against acquisition cost (CAC).
  • •Segment - averages hide unprofitable cohorts.
