There's no doubt that money can be made by owning shares of unprofitable businesses. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. 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 RedFlow (ASX:RFX) shareholders should 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'. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

Does RedFlow Have A Long Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at December 2023, RedFlow had cash of AU$9.7m and no debt. In the last year, its cash burn was AU$12m. Therefore, from December 2023 it had roughly 9 months of cash runway. 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 RedFlow's Cash Burn Changing Over Time?

In our view, RedFlow doesn't yet produce significant amounts of operating revenue, since it reported just AU$653k in the last twelve months. As a result, we think it's a bit early to focus on the revenue growth, so we'll limit ourselves to looking at how the cash burn is changing over time. As it happens, the company's cash burn reduced by 4.0% over the last year, which suggests that management may be mindful of the risks of their depleting cash reserves. While the past is always worth studying, it is the future that matters most of all. 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 RedFlow Raise Cash?

While RedFlow 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. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. 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.
