Free Cash Flow

What Is Free Cash Flow?

Free cash flow (FCF) is the cash generated by a company’s operations that is available after accounting for capital expenditures required to maintain or expand the asset base (Investopedia). FCF represents the cash that can be distributed to investors (debt holders and equity holders) without impairing the company’s operations.

In M&A, free cash flow is one of the most important financial metrics because it directly determines a company’s ability to service acquisition debt, fund future growth, and generate returns for investors.

Calculating Free Cash Flow

Basic Formula

Free Cash Flow = Operating Cash Flow − Capital Expenditures

EBITDA	Income statement
− Taxes paid	Cash flow statement
− Changes in working capital	Balance sheet movements
= Operating Cash Flow
− Capital expenditures (capex)	Cash flow statement
= Free Cash Flow

Unlevered vs Levered FCF

Type	What It Measures	Used For
Unlevered FCF (UFCF)	Cash available to all capital providers (debt + equity)	DCF valuation, enterprise value
Levered FCF (LFCF)	Cash available to equity holders after debt service	Equity valuation, dividend capacity

Unlevered FCF adds back interest expense (tax-adjusted) to remove the effect of the capital structure, making it comparable across companies with different leverage levels.

Why FCF Matters in M&A

Debt Service Capacity

In leveraged buyouts, FCF determines how much debt the target can support. Lenders evaluate:

• FCF-to-debt ratio — can the company generate enough cash to repay acquisition debt within the target timeframe?
• Debt service coverage — does FCF cover mandatory debt repayments and interest with an adequate margin of safety?
• Cash conversion — how reliably does EBITDA convert to actual cash flow?

Valuation

FCF is the foundation of discounted cash flow analysis — the most theoretically rigorous valuation methodology. The company’s value equals the present value of its expected future free cash flows, discounted at the WACC.

Cash Conversion Quality

The relationship between EBITDA and FCF reveals the quality of a company’s earnings:

Cash Conversion	Indication
FCF ≈ EBITDA	Highly capital-light business (SaaS, consulting)
FCF = 60–80% of EBITDA	Typical operating business
FCF = 30–50% of EBITDA	Capital-intensive business (manufacturing, infrastructure)
FCF well below EBITDA	High capex, working capital growth, or non-cash earnings

FCF vs EBITDA

Metric	FCF	EBITDA
Includes capex	Yes (deducted)	No
Includes working capital	Yes	No
Includes taxes	Yes (cash taxes)	No
Represents	Actual cash available	Operating profitability proxy
Best for	Valuation, debt capacity	Comparability, multiples

EBITDA is a proxy for operating profitability, while FCF measures actual cash generation. A company can have strong EBITDA but weak FCF if it requires heavy capital expenditure or has growing working capital needs.

Free Cash Flow in Asia Pacific

Free cash flow analysis in Asia Pacific M&A requires consideration of regional factors. In Japan, many listed companies have accumulated significant cash reserves relative to their market capitalisation, making FCF yield analysis central to activist and governance-driven M&A activity. In Australia, FCF analysis in resource sector transactions must account for lumpy capex cycles and commodity price volatility. In India and Southeast Asia, working capital intensity — driven by longer payment cycles and inventory requirements — can significantly reduce FCF relative to EBITDA. AI-native platforms like Amafi help investors analyse FCF profiles and value businesses across Asia Pacific sectors and geographies.
