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. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?

So should Vital Metals (ASX:VML) shareholders 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.

How Long Is Vital Metals' Cash Runway?

A company's cash runway is the amount of time it would take to burn through its cash reserves at its current cash burn rate. As at June 2021, Vital Metals had cash of AU$35m and no debt. Looking at the last year, the company burnt through AU$16m. Therefore, from June 2021 it had 2.2 years of cash runway. Arguably, that's a prudent and sensible length of runway to have. The image below shows how its cash balance has been changing over the last few years.

How Is Vital Metals' Cash Burn Changing Over Time?

Vital Metals 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. In fact, it ramped its spending strongly over the last year, increasing cash burn by 134%. It's fair to say that sort of rate of increase cannot be maintained for very long, without putting pressure on the balance sheet. Admittedly, we're a bit cautious of Vital Metals due to its lack of significant operating revenues. We prefer most of the stocks on this list of stocks that analysts expect to grow.

How Easily Can Vital Metals Raise Cash?

Given its cash burn trajectory, Vital Metals shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. Companies can raise capital through either debt or equity. Many companies end up issuing new shares to fund future 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.

Since it has a market capitalisation of AU$229m, Vital Metals' AU$16m in cash burn equates to about 7.0% of its 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.

Is Vital Metals' Cash Burn A Worry?
