Price-to-Sales Ratio for Companies Without Profits

Your screen for cheap stocks just dropped a company you wanted to look at. It lost money over the last four quarters, the P/E column says NM, and the filter threw it out. The business still sold things, though. It has a top line, and the top line is what price-to-sales runs on.

The arithmetic, two ways

There are two routes to the same answer: total market value against total revenue, or price per share against revenue per share. Take a hypothetical Company A with 100 million shares at $20 and revenue of $500 million over the trailing 12 months.

The routes agree as long as both use the same share count. Tools that take the two inputs from different dates show small gaps. They rarely matter.

Why it survives a bad year

Earnings are what’s left after every cost, interest payment, tax bill and accounting charge has been taken out of revenue, so a small shift in any of them can swing profit hard, flip it negative, or bury it under a one-time write-down. Revenue sits above all of that. It moves less in a rough year and has fewer judgment calls between the sale and the reported figure. That makes P/S usable for young companies that are spending ahead of profit, for businesses at the bottom of a cycle, and for anyone whose reported earnings got wrecked by a single charge.

Usable is a modest word here. The ratio can rank companies that P/E can’t touch. It can’t tell you whether any of them will ever earn money.

Revenue has soft spots of its own. A company that books the full price of goods it resells on behalf of others reports far more revenue than one that books only its commission, so two marketplaces with identical economics can carry very different P/S ratios. If a number looks odd, read the revenue recognition note in the annual report; reading a 10-K shows where it sits.

A dollar of sales at 5% versus 40%

A sales multiple is only as meaningful as the profit each dollar of sales eventually produces, and that depends entirely on margins.

Company B and Company C both trade at a P/S of 2. Company B keeps 5 cents of net profit from each dollar of revenue. Company C keeps 40 cents. Dividing P/S by net margin gives the P/E hiding behind each one.

The sales multiple is identical. The price paid for profit is eight times higher at B. For a company with no profit yet, the question becomes what margin it could reach at maturity, and that is a forecast you have to make yourself, because the ratio stays silent on it. Reading the three profit lines in gross, operating and net margin is the obvious next step after any P/S screen.

EV/Sales counts the debt

P/S uses market cap, which is only the equity. A company that has borrowed heavily looks cheaper on P/S than it really is, since a buyer of the whole business would take on that debt too. Enterprise value fixes this by adding debt and subtracting cash.

For a company with little debt the two numbers sit close together. For a leveraged one, EV/Sales is the honest figure. The same logic drives EV/EBITDA, which swaps revenue for a rough operating profit.

Compare within an industry

Picture a hypothetical software business with high gross margins at 8 times sales and a hypothetical grocery chain that keeps a sliver of each sale at 0.3 times, and notice that putting those two numbers side by side tells you only that the industries are built differently, since each could be fairly priced for what its revenue turns into. Screen within a sector. Better still, compare a company with the three or four businesses closest to it, which is the argument made in valuation needs peers.

Where to find it

Quote pages usually carry P/S in a valuation or statistics section, labeled Price/Sales, P/S or PSR, often with TTM next to it. Most screeners offer it as a filter.

Check the revenue period. Trailing 12 months is the common default, but some tools use the last fiscal year and a few offer a forward version built on revenue estimates, and a fast-growing company can look very different on each, since next year’s forecast revenue might be half again as large as last year’s actual figure. For a growing, unprofitable business, look at P/S alongside revenue growth and gross margin together, and treat a low reading as a reason to open the income statement.
