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, the natural question for Minbos Resources (ASX:MNB) shareholders is whether they should be concerned by its rate of cash burn. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

When Might Minbos Resources Run Out Of Money?

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 December 2022, Minbos Resources had cash of AU$17m and no debt. Importantly, its cash burn was AU$19m over the trailing twelve months. So it had a cash runway of approximately 11 months from December 2022. To be frank, this kind of short runway puts us on edge, as it indicates the company must reduce its cash burn significantly, or else raise cash imminently. The image below shows how its cash balance has been changing over the last few years.

How Is Minbos Resources' Cash Burn Changing Over Time?

While Minbos Resources did record statutory revenue of AU$96k over the last year, it didn't have any revenue from operations. That means we consider it a pre-revenue business, and we will focus our growth analysis on cash burn, for now. In fact, it ramped its spending strongly over the last year, increasing cash burn by 140%. That sort of spending growth rate can't continue for very long before it causes balance sheet weakness, generally speaking. Minbos Resources 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.

Can Minbos Resources Raise More Cash Easily?

Given its cash burn trajectory, Minbos Resources shareholders should already be thinking about how easy it might be for it to raise further 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 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$85m, Minbos Resources' AU$19m in cash burn equates to about 22% of its market value. That's fairly notable cash burn, so if the company had to sell shares to cover the cost of another year's operations, shareholders would suffer some costly dilution.

Is Minbos Resources' Cash Burn A Worry?

Minbos Resources is not in a great position when it comes to its cash burn situation. While its cash burn relative to its market cap wasn't too bad, its increasing cash burn does leave us rather nervous. Looking at the factors mentioned in this short report, we do think that its cash burn is a bit risky, and it does make us slightly nervous about the stock.
