About the metric
What EBITDA margin means
EBITDA margin measures EBITDA as a percentage of revenue. It can help compare operating profitability over time, but it excludes capital intensity, financing costs, taxes, and other items and is generally unsuitable for financial companies.
Calculation and source
How EBITDA margin is calculated
TickerStat calculates EBITDA margin as EBITDA divided by positive reported revenue for the same fiscal period. Changes are shown in percentage points. Fiscal periods can differ from calendar years, so exact period-end dates are included.
