EV/FCF Ratio: The Multiple That Capex Cannot Hide

Key Takeaways

• EV/FCF equals enterprise value divided by free cash flow to firm, the inverse of unlevered FCF yield.
• The ratio penalizes capex and working capital build-up that EV/EBITDA leaves untouched.
• Adjusted FCF definitions vary widely, so always check whether stock-based compensation is added back.
• A low EV/FCF can still be expensive if the underlying free cash flow is unsustainable.

What It Is

The EV/FCF ratio pairs enterprise value with free cash flow to the firm (FCFF). Free cash flow to the firm is the cash an operating business produces after taxes, capex, and working capital investment, but before any interest or debt repayments. It is the cash available to both debt and equity holders.

The Morgan Stanley Counterpoint Global review of multiples describes EV/FCF as the inverse of unlevered free cash flow yield, equal to FCFF divided by enterprise value. CFA Institute curriculum defines FCFF starting from net income, adding back non-cash and after-tax interest charges, and subtracting capex and working capital changes.

The Intuition

EBITDA is a profit number. Free cash flow is a cash number. The gap between them is everything a business has to spend to keep running and growing: depreciation that funds replacement capex, working capital that finances accounts receivable, and the gap between accrual revenue and cash collections.

Two firms at the same EV/EBITDA can have very different EV/FCF if one has heavy capex requirements and the other does not. The EV/FCF ratio reveals what EBITDA hides. For a capital-light software business, EV/FCF and EV/EBITDA converge. For a capital-heavy telecom, the gap can be a factor of two or more.

How It Works

The formula is:

EV/FCF = Enterprise Value / Free Cash Flow to the Firm

Where free cash flow to the firm is:

FCFF = NOPAT + D&A - Capex - Change in Working Capital

NOPAT (net operating profit after taxes) equals operating income times one minus the tax rate. The inverse, FCF yield, is sometimes preferred for intuition: an EV/FCF of 20 implies a 5% unlevered yield, and an EV/FCF of 10 implies a 10% yield.

Many practitioners use forward FCF based on consensus or modelled estimates. Maintenance FCF, which strips growth capex out of total capex, is a related cut that aims to isolate the cash the business throws off without reinvesting for growth.

Worked Example

A regulated telecom has 1,000 million shares at $25, total debt of $30 billion, and cash of $2 billion. Reported FCFF is $3 billion after $7 billion of capex.

• Equity value = 1,000 x $25 = $25 billion
• Net debt = 30 - 2 = $28 billion
• Enterprise value = 25 + 28 = $53 billion
• EV/FCF = 53,000 / 3,000 = 17.7

If the same firm reports $10 billion of EBITDA, EV/EBITDA is 5.3, which looks cheap. The gap between 5.3 and 17.7 is the capex burden. An investor asking whether the firm can fund a dividend or reduce debt is far better served by the EV/FCF figure. A peer at 12x EV/FCF with the same growth would deserve a deeper look.

Common Mistakes

1. Confusing levered and unlevered FCF. EV is paid to both debt and equity, so the matching cash flow is FCFF, not free cash flow to equity. Mixing the two understates the multiple.
2. Ignoring stock-based compensation. Companies often present FCF after adding back stock-based compensation as if it were a non-cash charge. The Morgan Stanley review warns that this materially inflates reported FCF for tech firms.
3. Single-year FCF noise. Capex is lumpy. A factory build year can crater FCF and inflate the multiple even when steady-state economics are fine. Average across three to five years for cyclicals.
4. Pension and lease distortions. Pension contributions, large legal settlements, and lease accounting changes can swing FCF. Normalize or strip out non-recurring items.
5. Forgetting growth capex. If growth capex is sustaining a high-return investment opportunity, a low free cash flow today should not be penalized as harshly as a low FCF caused by maintenance needs alone.

Frequently Asked Questions

What is the EV/FCF ratio in simple terms? The EV/FCF ratio is the total value of a business, including debt, divided by the cash it actually produces after capex and working capital. An EV/FCF of 15 means the price equals 15 years of current free cash flow.

How does the EV/FCF ratio affect investment decisions? EV/FCF reveals whether a firm's reported earnings translate into cash. Investors with long horizons use it to compare cash yields across capital structures and industries, since it is harder to manipulate than EBITDA.

What is a real-world example of the EV/FCF ratio? Large capital-light platform businesses can trade in a 25 to 40 EV/FCF range, while capital-heavy telecoms or utilities often land between 10 and 20, reflecting the ongoing capex required to sustain the asset base.

How can investors use the EV/FCF ratio effectively? Average across at least three years to smooth capex cycles. Check whether stock-based compensation is added back. Always pair the multiple with capex intensity and the cost of capital.

How is the EV/FCF ratio different from EV/EBITDA? EV/EBITDA ignores capex and working capital. EV/FCF includes both. The gap between the two multiples is a fast measure of how cash-intensive the business is.
