P/E vs EV/EBIT: Why Two Stocks at the Same P/E Are Not the Same Price

The price-to-earnings ratio is the first multiple everyone learns and the last many give up. It has a rare quality: you can work it out in your head. It has a flaw that often cancels that quality out: it sees only part of the price you pay.

What the P/E leaves out

Buying a share means buying a slice of the equity. But a company does not belong to its shareholders alone: its lenders hold a prior claim on its assets. Taking over an indebted business means taking over its debt as well.

The P/E ignores this entirely. It compares a market capitalization to a net profit, and debt appears nowhere — except indirectly, through interest already deducted from earnings.

Enterprise value corrects the perspective:

> Enterprise value = market capitalization + net financial debt − cash

It is the price of the whole business, debt included and cash deducted. Divided by operating profit (EBIT) — earnings before interest and taxes, therefore before financing choices come into play — it gives you EV/EBIT.

Two companies, one P/E, two prices

Take two businesses earning exactly the same, trading at the same multiple of earnings.

Illustrative figures, shown to demonstrate the calculation.

On a P/E basis the two are identical. In reality, whoever buys A pays $800 million for the operating business, because $400 million of cash comes back with it. Whoever buys B pays $1.8 billion, debt included. For the same earnings, one costs more than twice the other.

The P/E will never tell you this. EV/EBIT tells you at once.

Where the P/E misleads most

Three situations where relying on it means comparing things that are not comparable.

Balance sheets heavy with debt, or heavy with cash

The case in the table above, and a common one. A company sitting on cash worth a third of its market capitalization looks expensive on earnings while being cheap on enterprise value.

Different financing structures

Comparing an equity-financed company with a debt-financed one on a P/E basis makes little sense: the second reports net profit reduced by interest, hence a higher P/E, without its operations being any less profitable. EBIT sits above interest: it compares businesses, not financing decisions.

Earnings distorted by one-off items

An asset disposal inflates one year's net profit and artificially compresses the P/E. A stock will appear to trade at 6 times earnings when its recurring business is priced at 15. Operating profit contains no such gains.

Loss-making years

A company with negative earnings has no meaningful P/E at all — the ratio is either shown as blank or as a nonsensical negative number, and screening tools routinely drop such companies from consideration. Yet a business can be loss-making at the bottom line while its operations remain profitable, once unusual charges or heavy interest are set aside. EV/EBIT still produces a usable figure in those cases, which is one of the moments when the difference matters most: the cheapest opportunities often appear precisely where the simplest ratio stops working.

A third figure worth adding: the yield

Both ratios can be inverted, and the inverted form is often easier to think about. The earnings yield is the reciprocal of the P/E: a stock at 12 times earnings offers an earnings yield of roughly 8.3%. EBIT divided by enterprise value gives the same idea at the level of the whole business.

Illustrative figures, shown to demonstrate the calculation.

Expressed as a yield, the number invites the only comparison that matters over time: against the return available elsewhere, and in particular against long-term government bonds. A business priced at 25 times earnings offers 4% while carrying commercial risk; the same 4% from a sovereign bond carries none. That comparison does not decide anything on its own, but it puts a valuation in context far better than a multiple considered in isolation.

What EV/EBIT does not solve

Replacing one with the other everywhere would be the mirror-image mistake.

• EBIT ignores the real cost of debt. It compares operations regardless of financing, which is useful for comparison — but shareholders receive what is left after interest. A heavily indebted company can show a respectable EV/EBIT while leaving almost nothing to its owners.
• EBIT is not cash. Depreciation is deducted although no money leaves; maintenance capital expenditure leaves although it never appears. For capital-intensive businesses the gap is substantial.
• Net debt is a snapshot. Measured on December 31, it may have been tidied for the occasion — a practice known as window dressing. Off-balance-sheet commitments, leases and pension obligations do not always show up.

Using them together

No single multiple is sufficient, and the value lies precisely in their disagreement. When the P/E looks attractive and EV/EBIT does not, the answer is almost always on the balance sheet: debt. When EV/EBIT looks attractive and the P/E does not, look at financial charges or an unusual tax position.

This is why a serious ranking is never built on one ratio. Ours combines several valuation measures with quality and financial-strength criteria, precisely so that no isolated weakness can push a company to the top.

The useful habit fits in a single question, asked before any other: does this ratio include debt, yes or no? The P/E does not; EV/EBIT does. Everything else follows from that.
