EBITDA Margin

I. Formal Definition

EBITDA as a percentage of revenue, providing a non-GAAP profitability ratio that allows cross-period and cross-organisation comparison while abstracting from financing and accounting policy choices. EBITDA margin is widely used in private market valuation but suffers from the same definitional drift as EBITDA itself. The federation requires EBITDA margin to be reported with the federation-standard adjustments only, and any custom adjustments to be footnoted with quantification under UFMS-001:3.2. Steward tier accreditation reviews multi-period margin trend.

II. Etymology

A natural extension of EBITDA into ratio form; the construction stabilised in the leveraged buyout era and spread to general corporate finance.

III. Federation Usage

Federation members publish EBITDA margin with federation-standard adjustments. Custom adjustments are footnoted. Multi-period trend is reviewed at steward tier accreditation under MEV-Annex:4.1. Aggressive add-back patterns are flagged as conduct concerns.
