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. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

Given this risk, we thought we'd take a look at whether Satellos Bioscience (TSE:MSCL) shareholders should be worried about its cash burn. 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. First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

When Might Satellos Bioscience Run Out Of Money?

You can calculate a company's cash runway by dividing the amount of cash it has by the rate at which it is spending that cash. As at June 2024, Satellos Bioscience had cash of CA$28m and no debt. Importantly, its cash burn was CA$22m over the trailing twelve months. That means it had a cash runway of around 15 months as of June 2024.

The image below shows how its cash balance has been changing over the last few years.

How Is Satellos Bioscience's Cash Burn Changing Over Time?

Satellos Bioscience didn't record any revenue over the last year, indicating that it's an early stage company still developing its business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. In fact, it ramped its spending strongly over the last year, increasing cash burn by 186%. It's fair to say that sort of rate of increase cannot be maintained for very long, without putting pressure on the balance sheet. Clearly, however, the crucial factor is whether the company will grow its business going forward. So you might want to take a peek at how much the company is expected to grow in the next few years.

How Easily Can Satellos Bioscience Raise Cash?
