There's no doubt that money can be made by owning shares of unprofitable businesses. 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. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.
So, the natural question for Satellos Bioscience (TSE:MSCL) shareholders is whether they should be concerned by its rate of 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. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.
A cash runway is defined as the length of time it would take a company to run out of money if it kept spending at its current rate of cash burn. In September 2025, Satellos Bioscience had US$35m in cash, and was debt-free. Looking at the last year, the company burnt through US$21m. So it had a cash runway of approximately 20 months from September 2025. 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.

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. Over the last year its cash burn actually increased by 42%, which suggests that management are increasing investment in future growth, but not too quickly. However, the company's true cash runway will therefore be shorter than suggested above, if spending continues to increase. While the past is always worth studying, it is the future that matters most of all. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.
Given its cash burn trajectory, Satellos Bioscience shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. Commonly, a business will sell new shares in itself to raise cash and drive growth. We can compare a company's cash burn to its market capitalisation to get a sense for how many new shares a company would have to issue to fund one year's operations.
Satellos Bioscience has a market capitalisation of US$94m and burnt through US$21m last year, which is 23% of the company's market value. That's not insignificant, and if the company had to sell enough shares to fund another year's growth at the current share price, you'd likely witness fairly costly dilution.
Even though its increasing cash burn makes us a little nervous, we are compelled to mention that we thought Satellos Bioscience's cash runway was relatively promising. Even though we don't think it has a problem with its cash burn, the analysis we've done in this article does suggest that shareholders should give some careful thought to the potential cost of raising more money in the future. On another note, Satellos Bioscience has 3 warning signs (and 1 which doesn't sit too well with us) we think you should know about.
