Just because a business does not make any money, does not mean that the stock will go down. 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 Bannerman Energy (ASX:BMN) 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. Let's start with an examination of the business' cash, relative to its cash burn.
When Might Bannerman Energy Run Out Of Money?
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 Bannerman Energy last reported its December 2024 balance sheet in March 2025, it had zero debt and cash worth AU$81m. Importantly, its cash burn was AU$34m over the trailing twelve months. So it had a cash runway of about 2.4 years from December 2024. Importantly, analysts think that Bannerman Energy will reach cashflow breakeven in 3 years. That means it doesn't have a great deal of breathing room, but it shouldn't really need more cash, considering that cash burn should be continually reducing. The image below shows how its cash balance has been changing over the last few years.

How Is Bannerman Energy's Cash Burn Changing Over Time?
Because Bannerman Energy 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. In fact, it ramped its spending strongly over the last year, increasing cash burn by 186%. 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.
Can Bannerman Energy Raise More Cash Easily?
Given its cash burn trajectory, Bannerman Energy 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. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund growth. By looking at a company's cash burn relative to its market capitalisation, we gain insight on how much shareholders would be diluted if the company needed to raise enough cash to cover another year's cash burn.
