EBITDA vs. Cash from Operations (CFO)

What each measures

EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) starts from operating income and adds back D&A. It's a non-GAAP proxy for operating cash that ignores capital structure and accounting choices around long-lived assets.

Cash from Operations (CFO) is the GAAP-compliant cash measure on the cash flow statement, computed by adjusting net income for non-cash items AND for changes in working capital. CFO captures the cash drag of growing receivables and inventory; EBITDA does not.

When they diverge

A growing business often shows EBITDA significantly above CFO because each new dollar of revenue generates a fraction of a dollar of new working capital that must be funded with cash. The gap is normal and recoverable as growth slows.

A persistent gap where EBITDA is far above CFO with no growth justification is a warning. It can indicate aggressive revenue recognition, weakening collections, or inventory build-up. Famously, WorldCom and Enron both had healthy EBITDA and deteriorating CFO before their accounting fraud became public.

Why the gap matters

EBITDA strips out interest, taxes, depreciation, and amortization but ignores changes in working capital, capex, and stock-based compensation. CFO (cash flow from operations) includes working capital but excludes capex. A persistent EBITDA-to-CFO gap is one of the most useful diagnostics in financial analysis — it usually means working capital is consuming cash faster than EBITDA suggests.

Stock-based compensation is the fashionable adjustment of the late 2010s and 2020s. Public-company adjusted EBITDA often adds back stock-based comp, but it's a real economic cost — shareholders are diluted whether the company expenses it or not. A business that requires $20M of stock-based comp annually to attract talent has a real $20M cost that doesn't show up in adjusted EBITDA.

For private-company valuation, banks and PE buyers focus on EBITDA but adjust for owner add-backs, one-time items, and normalized capex. The negotiated multiple applies to that normalized number. Owners preparing for a sale should track and document the bridge from reported EBITDA to adjusted EBITDA quarterly so the conversation in due diligence is short and well-supported.

When EBITDA and CFO diverge for more than one quarter, the audit committee or owner should request a bridge analysis. The bridge starts with EBITDA and walks down to CFO line by line: working capital changes, capex (if subtracted), stock-based comp add-backs reversed, deferred tax movements, etc. The exercise usually surfaces one or two specific items driving the gap and either confirms they're temporary or identifies a problem.
