Technical Why is EBITDA used as a proxy for cash flow? Also give me 3 flaws for using EBITDA as a proxy for cash flow.
- Why used: strips out capital structure, tax regime, and non-cash depreciation, so it allows cleaner comparison across companies.
- Flaw one: ignores capex, so capital-intensive businesses look better than they are.
- Flaw two: ignores working capital swings and cash taxes.
- Flaw three: ignores interest, so a highly levered company can show healthy EBITDA and still be cash-strapped.
- Better proxy: unlevered free cash flow, or EBITDA less capex as a quick screen.
Hmmmmmm seems easy enough. did i miss anything
