There's no doubt that money can be made by owning shares of unprofitable businesses. For example, although software-as-a-service business Salesforce.com lost money for years while it grew recurring revenue, if you held shares since 2005, you'd have done very well indeed. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.
Given this risk, we thought we'd take a look at whether Black Iron (TSE:BKI) shareholders should be worried about its cash burn. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. Let's start with an examination of the business' cash, relative to its cash burn.
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 June 2026, Black Iron had US$1.7m in cash, and was debt-free. Importantly, its cash burn was US$1.4m over the trailing twelve months. Therefore, from June 2026 it had roughly 15 months of cash runway. While that cash runway isn't too concerning, sensible holders would be peering into the distance, and considering what happens if the company runs out of cash. You can see how its cash balance has changed over time in the image below.

Black Iron didn't record any revenue over the last year, indicating that it's an early stage company still developing its 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. While it hardly paints a picture of imminent growth, the fact that it has reduced its cash burn by 27% over the last year suggests some degree of prudence. Black Iron makes us a little nervous due to its lack of substantial operating revenue. We prefer most of the stocks on this list of stocks that analysts expect to grow.
Even though it has reduced its cash burn recently, shareholders should still consider how easy it would be for Black Iron to raise more cash in the future. Companies can raise capital through either debt or equity. Many companies end up issuing new shares to fund future growth. By looking at a company's cash burn relative to its market capitalisation, we gain insight on how much shareholders would be diluted if the company needed to raise enough cash to cover another year's cash burn.
Black Iron has a market capitalisation of US$22m and burnt through US$1.4m last year, which is 6.3% of the company's market value. That's a low proportion, so we figure the company would be able to raise more cash to fund growth, with a little dilution, or even to simply borrow some money.
Black Iron appears to be in pretty good health when it comes to its cash burn situation. One the one hand we have its solid cash burn reduction, while on the other it can also boast very strong cash burn relative to its market cap. While we're the kind of investors who are always a bit concerned about the risks involved with cash burning companies, the metrics we have discussed in this article leave us relatively comfortable about Black Iron's situation.
