There's no doubt that money can be made by owning shares of unprofitable businesses. 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. 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 should Anixa Biosciences (NASDAQ:ANIX) shareholders be worried about its 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. First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

When Might Anixa Biosciences 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 Anixa Biosciences last reported its October 2024 balance sheet in January 2025, it had zero debt and cash worth US$20m. In the last year, its cash burn was US$7.3m. That means it had a cash runway of about 2.7 years as of October 2024. Importantly, analysts think that Anixa Biosciences will reach cashflow breakeven in 5 years. That means unless the company reduces its cash burn quickly, it may well look to raise more cash. The image below shows how its cash balance has been changing over the last few years.

How Is Anixa Biosciences' Cash Burn Changing Over Time?

Because Anixa Biosciences 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. With the cash burn rate up 18% in the last year, it seems that the company is ratcheting up investment in the business over time. That's not necessarily a bad thing, but investors should be mindful of the fact that will shorten the cash runway. 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 Hard Would It Be For Anixa Biosciences To Raise More Cash For Growth?

While Anixa Biosciences 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. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. Many companies end up issuing new shares to fund future 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$72m, Anixa Biosciences' US$7.3m in cash burn equates to about 10% of its market value. Given that situation, it's fair to say the company wouldn't have much trouble raising more cash for growth, but shareholders would be somewhat diluted.

So, Should We Worry About Anixa Biosciences' Cash Burn?

As you can probably tell by now, we're not too worried about Anixa Biosciences' cash burn. In particular, we think its cash runway stands out as evidence that the company is well on top of its spending. While its increasing cash burn wasn't great, the other factors mentioned in this article more than make up for weakness on that measure. Shareholders can take heart from the fact that analysts are forecasting it will reach breakeven. 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.
