We can readily understand why investors are attracted to unprofitable companies. 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?

Given this risk, we thought we'd take a look at whether Blackstone Minerals (ASX:BSX) 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. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

How Long Is Blackstone Minerals' 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. When Blackstone Minerals last reported its balance sheet in June 2022, it had zero debt and cash worth AU$41m. In the last year, its cash burn was AU$36m. That means it had a cash runway of around 13 months as of June 2022. Notably, however, analysts think that Blackstone Minerals will break even (at a free cash flow level) before then. If that happens, then the length of its cash runway, today, would become a moot point. Depicted below, you can see how its cash holdings have changed over time.

How Is Blackstone Minerals' Cash Burn Changing Over Time?

Although Blackstone Minerals reported revenue of AU$36k last year, it didn't actually have any revenue from operations. To us, that makes it a pre-revenue company, so we'll look to its cash burn trajectory as an assessment of its cash burn situation. In fact, it ramped its spending strongly over the last year, increasing cash burn by 138%. It's fair to say that sort of rate of increase cannot be maintained for very long, without putting pressure on the balance sheet. Clearly, however, the crucial factor is whether the company will grow its business going forward. So you might want to take a peek at how much the company is expected to grow in the next few years.

How Easily Can Blackstone Minerals Raise Cash?

Given its cash burn trajectory, Blackstone Minerals 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. 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).

Since it has a market capitalisation of AU$71m, Blackstone Minerals' AU$36m in cash burn equates to about 51% of its market value. From this perspective, it seems that the company spent a huge amount relative to its market value, and we'd be very wary of a painful capital raising.

So, Should We Worry About Blackstone Minerals' Cash Burn?

On this analysis of Blackstone Minerals' cash burn, we think its cash runway was reassuring, while its increasing cash burn has us a bit worried. It's clearly very positive to see that analysts are forecasting the company will break even fairly soon. 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 Blackstone Minerals' situation. Taking a deeper dive, we've spotted 3 warning signs for Blackstone Minerals you should be aware of, and 1 of them makes us a bit uncomfortable.
