High-Growth and Negative-Earnings Companies

How to think about the value of a company that's growing fast and losing money, by working forward to what it could earn at maturity and back to what that's worth today.

Lesson 8 of 10 · 7 min read · Advanced · Members · Last reviewed October 2026

The short version

A company with no profit can't be valued on its earnings, and a multiple of revenue says little, because revenue only matters for the profit it eventually produces. The practical method is to picture the company at maturity: how large its sales could be, what margin a business like it earns, and what that would be worth then. Discount that back to today, divide by the larger number of shares that will exist by then, and allow for the chance it never gets there. The result is very sensitive to a few assumptions, which is the main lesson. Most of the value sits many years away, and the range of outcomes is wide.

By the end of this lesson, you'll be able to

  • Estimate the value of a loss-making company from its potential revenue and margin at maturity
  • Adjust for the dilution and the risk of failure on the way there
  • Translate a price-to-sales ratio into the growth and margins it requires

Why this matters

Some of the most talked-about companies report losses. They're spending heavily to grow, and their value depends almost entirely on profits that are years away. The tools from Part 4 seem to break: there's no price-to-earnings ratio, and a DCF starts from negative cash flow. The principle hasn't changed, though. A business is still worth the cash it will eventually produce. What changes is how far ahead you have to look, and how uncertain the view is.

Why revenue multiples aren't enough

With no earnings to use, investors often quote price to sales. Other Multiples: P/S, P/B, and EV/EBITDA introduced it and gave the warning that applies here: a dollar of revenue is worth very different amounts depending on how much of it becomes profit.

A revenue multiple can be translated into something more familiar. A company valued at 15 times its sales, which will one day keep 20% of sales as profit, is valued at 75 times the profit it would earn on today's sales at that future margin. Its price makes sense only if sales grow many times over before that margin arrives.

Working from maturity

Instead of forecasting each year's loss, start at the end.

  1. How large could revenue be when growth slows to an ordinary pace?
  2. What margin does a mature business of this kind earn?
  3. What would that profit be worth at that point?
  4. What is that worth today, discounted at a rate that reflects the risk?
  5. How many shares will exist by then?
  6. What's the chance it gets there at all?
Worked example: Company H (hypothetical)
Amount
Revenue today$100 million
Free cash flow today$40 million outflow
Shares today, and share price50 million at $30
Market value today$1,500 million, or 15 times sales
Revenue in year 10, with growth slowing from 40% to 6%$600 million
Free cash flow margin at maturity20%
Free cash flow in year 10$120 million
Value in year 10, at 20 times free cash flow$2,400 million
Value today, discounted at 11% a year$845 million
Shares by year 1065 million
Value per share today$13.00

In this forecast Company H's sales grow sixfold in ten years, which is about 20% a year, and it becomes a solidly profitable business. Even so, the estimate is $13 a share against a price of $30. The forecast isn't pessimistic. The price simply assumes much more.

Each step deserves a comment.

  • Revenue at maturity should be checked against the size of the market the company sells into. Growth slows as a company gets larger, because each year's increase has to be bigger than the last in dollars.
  • The mature margin is best taken from established companies with a similar way of doing business, not from management's long-term target.
  • The discount rate is higher than for a steady business, because the outcome is less certain. Cost of Capital explained why riskier cash flows are discounted at higher rates.
