The two directions
Going forward, you multiply EBITDA by a multiple taken from similar companies to get enterprise value, then cross the bridge to equity value. Going backward, you start with a market price, add net debt to reach enterprise value, and divide by EBITDA to see how richly the market values each dollar of operating profit.
EV = EBITDA x multiple. Equity value = EV - debt + cash. Value per share = equity value / shares. Implied multiple = (price x shares + debt - cash) / EBITDA. This version leaves out preferred stock and minority interest; the bridge calculator handles those.
A worked example
A company earns EBITDA of $85 million. It has $250 million of debt, $40 million of cash and 20 million shares. Comparable companies trade near 9.5 times EBITDA.
| Multiple | Enterprise value | Equity value | Per share |
|---|---|---|---|
| 8.0x | $680.00 | $470.00 | $23.50 |
| 9.5x | $807.50 | $597.50 | $29.88 |
| 11.0x | $935.00 | $725.00 | $36.25 |
At 9.5x, enterprise value is $807.5 million. After subtracting $250 million of debt and adding $40 million of cash, equity value is $597.5 million, or $29.88 a share. Now suppose the stock trades at $31. Equity value is $620 million and enterprise value $830 million, so the market is paying 9.76 times EBITDA. That is a little richer than the 9.5x benchmark.
Using a multiple sensibly
A multiple is only as good as the comparison behind it. Companies in the same industry with similar growth, margins and size should trade at similar multiples. A faster grower deserves a higher one. Use the same period for EBITDA and for the comparables, such as the last twelve months, and the same definition of EBITDA, adjusted the same way for one-off items.
EBITDA ignores capital spending and taxes, so two companies with the same multiple can have very different cash flows. Capital-heavy businesses often trade at lower EV/EBITDA than asset-light ones for that reason. The calculator rejects zero or negative EBITDA because a multiple of a loss has no useful meaning.
Mistakes that cost points
- Applying an EV multiple and calling the answer a share price without subtracting debt and adding cash.
- Comparing a multiple built on next year's EBITDA with one built on last year's.
- Picking comparables that differ in size, growth or industry and then trusting the average.
- Dividing market cap by EBITDA. The numerator and denominator must both be enterprise-level.
- Using a multiple on negative EBITDA.
