We can readily understand why investors are attracted to unprofitable companies. For example, although Amazon.com made losses for many years after listing, if you had bought and held the shares since 1999, you would have made a fortune. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?

For the purposes of this article, cash burn is the annual rate at which an unprofitable company spends cash to fund its growth; its negative free cash flow.

When Might Turnstone Biologics Run Out Of Money?
A company's cash runway is calculated by dividing its cash hoard by its cash burn. In March 2024, Turnstone Biologics had US$78m in cash, and was debt-free. Looking at the last year, the company burnt through US$67m. Therefore, from March 2024 it had roughly 14 months of cash runway. That's not too bad, but it's fair to say the end of the cash runway is in sight, unless cash burn reduces drastically. Depicted below, you can see how its cash holdings have changed over time.
How Is Turnstone Biologics' Cash Burn Changing Over Time?
Because Turnstone Biologics isn't currently generating revenue, we consider it an early-stage business. So while we can't look to sales to understand growth, we can look at how the cash burn is changing to understand how expenditure is trending over time. As it happens, the company's cash burn reduced by 13% over the last year, which suggests that management are maintaining a fairly steady rate of business development, albeit with a slight decrease in spending. While the past is always worth studying, it is the future that matters most of all. So you might want to take a peek at how much the company is expected to grow in the next few years.
How Hard Would It Be For Turnstone Biologics To Raise More Cash For Growth?
