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 the successes are well known, investors should not ignore the very many unprofitable companies that simply burn through all their cash and collapse.
Given this risk, we thought we'd take a look at whether Zanaga Iron Ore (LON:ZIOC) shareholders should be worried about its cash burn. In this article, we define cash burn as its annual (negative) free cash flow, which is the amount of money a company spends each year to fund its growth. 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. As at June 2026, Zanaga Iron Ore had cash of US$5.4m and no debt. Looking at the last year, the company burnt through US$3.7m. So it had a cash runway of approximately 17 months from June 2026. 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. You can see how its cash balance has changed over time in the image below.

Because Zanaga Iron Ore isn't currently generating revenue, we consider it an early-stage business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. While it hardly paints a picture of imminent growth, the fact that it has reduced its cash burn by 33% over the last year suggests some degree of prudence. Clearly, however, the crucial factor is whether the company will grow its business going forward. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.
While Zanaga Iron Ore is showing a solid reduction in its cash burn, it's still worth considering how easily it could raise more cash, even just to fuel faster growth. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. 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.
Zanaga Iron Ore's cash burn of US$3.7m is about 8.7% of its US$43m market capitalisation. Given that is a rather small percentage, it would probably be really easy for the company to fund another year's growth by issuing some new shares to investors, or even by taking out a loan.
Zanaga Iron Ore 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 Zanaga Iron Ore's situation.
