We can readily understand why investors are attracted to unprofitable companies. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

So, the natural question for SOS (NYSE:SOS) 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'. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

Does SOS Have A Long 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 2024, SOS had cash of US$247m and no debt. In the last year, its cash burn was US$42m. Therefore, from June 2024 it had 5.9 years of cash runway. Even though this is but one measure of the company's cash burn, the thought of such a long cash runway warms our bellies in a comforting way. The image below shows how its cash balance has been changing over the last few years.

Is SOS' Revenue Growing?

Given that SOS actually had positive free cash flow last year, before burning cash this year, we'll focus on its operating revenue to get a measure of the business trajectory. Regrettably, the company's operating revenue moved in the wrong direction over the last twelve months, declining by 49%. In reality, this article only makes a short study of the company's growth data. This graph of historic earnings and revenue shows how SOS is building its business over time.

How Easily Can SOS Raise Cash?

Given its problematic fall in revenue, SOS shareholders should consider how the company could fund its growth, if it turns out it needs more cash. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. Commonly, a business will sell new shares in itself to raise cash and drive 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 US$57m, SOS' US$42m in cash burn equates to about 73% of its market value. That's very high expenditure relative to the company's size, suggesting it is an extremely high risk stock.

So, Should We Worry About SOS' Cash Burn?

On this analysis of SOS' cash burn, we think its cash runway was reassuring, while its cash burn relative to its market cap has us a bit worried. Even though we don't think it has a problem with its cash burn, the analysis we've done in this article does suggest that shareholders should give some careful thought to the potential cost of raising more money in the future.
