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. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.
So should Clean Air Metals (CVE:AIR) shareholders 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. When Clean Air Metals last reported its October 2025 balance sheet in December 2025, it had zero debt and cash worth CA$1.6m. Importantly, its cash burn was CA$2.5m over the trailing twelve months. That means it had a cash runway of around 8 months as of October 2025. That's quite a short cash runway, indicating the company must either reduce its annual cash burn or replenish its cash. You can see how its cash balance has changed over time in the image below.

Because Clean Air Metals 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. Given the length of the cash runway, we'd interpret the 42% reduction in cash burn, in twelve months, as prudent if not necessary for capital preservation. Admittedly, we're a bit cautious of Clean Air Metals due to its lack of significant operating revenues. So we'd generally prefer stocks from this list of stocks that have analysts forecasting growth.
While Clean Air Metals 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. By comparing a company's annual cash burn to its total market capitalisation, we can estimate roughly how many shares it would have to issue in order to run the company for another year (at the same burn rate).
Clean Air Metals has a market capitalisation of CA$28m and burnt through CA$2.5m last year, which is 9.0% 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.
On this analysis of Clean Air Metals' cash burn, we think its cash burn relative to its market cap was reassuring, while its cash runway has us a bit worried. We don't think its cash burn is particularly problematic, but after considering the range of factors in this article, we do think shareholders should be monitoring how it changes over time.
