We're Not Very Worried About Atossa Therapeutics' (NASDAQ:ATOS) Cash Burn Rate

We can readily understand why investors are attracted to unprofitable companies. For example, although software-as-a-service business Salesforce.com lost money for years while it grew recurring revenue, if you held shares since 2005, you'd have done very well indeed. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

So, the natural question for Atossa Therapeutics (NASDAQ:ATOS) 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.

Does Atossa Therapeutics 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 September 2022, Atossa Therapeutics had cash of US$117m and no debt. Importantly, its cash burn was US$20m over the trailing twelve months. That means it had a cash runway of about 5.9 years as of September 2022. While this is only one measure of its cash burn situation, it certainly gives us the impression that holders have nothing to worry about. The image below shows how its cash balance has been changing over the last few years.

How Is Atossa Therapeutics' Cash Burn Changing Over Time?

Atossa Therapeutics didn't record any revenue over the last year, indicating that it's an early stage company still developing its business. So while we can't look to sales to understand growth, we can look at how the cash burn is changing to understand how expenditure is trending over time. With the cash burn rate up 23% in the last year, it seems that the company is ratcheting up investment in the business over time. However, the company's true cash runway will therefore be shorter than suggested above, if spending continues to increase. 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.

Can Atossa Therapeutics Raise More Cash Easily?

While Atossa Therapeutics does have a solid cash runway, its cash burn trajectory may have some shareholders thinking ahead to when the company may need to raise more cash. 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. 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.

Atossa Therapeutics' cash burn of US$20m is about 22% of its US$91m market capitalisation. That's not insignificant, and if the company had to sell enough shares to fund another year's growth at the current share price, you'd likely witness fairly costly dilution.

So, Should We Worry About Atossa Therapeutics' Cash Burn?

Even though its increasing cash burn makes us a little nervous, we are compelled to mention that we thought Atossa Therapeutics' cash runway was relatively promising. Based on the factors mentioned in this article, we think its cash burn situation warrants some attention from shareholders, but we don't think they should be worried.
