The EV/EBITDA ratio (the enterprise multiple) compares enterprise value (EV) to trailing twelve-month (TTM) EBITDA. EV is calculated as market capitalisation + total debt − cash & short-term investments. Because EV/EBITDA is capital-structure-neutral and ignores non-cash depreciation and amortisation, it is the standard multiple used in M&A and for cross-company or cross-border comparisons. Note: this calculation uses a simplified EV (minority interest and preferred equity excluded due to data availability), consistent with most public financial-data providers.
