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. But while the successes are well known, investors should not ignore the very many unprofitable companies that simply burn through all their cash and collapse.

So, the natural question for Genelux (NASDAQ:GNLX) shareholders is whether they should be concerned by its rate of 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. Let's start with an examination of the business' cash, relative to its cash burn.

How Long Is Genelux's Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. Genelux has such a small amount of debt that we'll set it aside, and focus on the US$30m in cash it held at September 2023. Looking at the last year, the company burnt through US$16m. That means it had a cash runway of around 23 months as of September 2023. While that cash runway isn't too concerning, sensible holders would be peering into the distance, and considering what happens if the company runs out of cash. You can see how its cash balance has changed over time in the image below.

How Is Genelux's Cash Burn Changing Over Time?

Whilst it's great to see that Genelux has already begun generating revenue from operations, last year it only produced US$238k, so we don't think it is generating significant revenue, at this point. 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. Its cash burn positively exploded in the last year, up 1,342%. With that kind of spending growth its cash runway will shorten quickly, as it simultaneously uses its cash while increasing the burn rate. 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 Genelux Raise Cash?

Given its cash burn trajectory, Genelux 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. 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 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 US$394m, Genelux's US$16m in cash burn equates to about 4.0% of its market value. That's a low proportion, so we figure the company would be able to raise more cash to fund growth, with a little dilution, or even to simply borrow some money.

How Risky Is Genelux's Cash Burn Situation?

Even though its increasing cash burn makes us a little nervous, we are compelled to mention that we thought Genelux's cash burn relative to its market cap was relatively promising. Cash burning companies are always on the riskier side of things, but after considering all of the factors discussed in this short piece, we're not too worried about its rate of cash burn. Taking a deeper dive, we've spotted 6 warning signs for Genelux you should be aware of, and 3 of them are concerning.
