We're Keeping An Eye On Annexon's (NASDAQ:ANNX) Cash Burn Rate

There's no doubt that money can be made by owning shares of unprofitable businesses. 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 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 Annexon (NASDAQ:ANNX) shareholders should 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 Annexon Run Out Of Money?

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 December 2021, Annexon had cash of US$243m and no debt. In the last year, its cash burn was US$108m. That means it had a cash runway of about 2.3 years as of December 2021. Arguably, that's a prudent and sensible length of runway to have. The image below shows how its cash balance has been changing over the last few years.

How Is Annexon's Cash Burn Changing Over Time?

Annexon didn't record any revenue over the last year, indicating that it's an early stage company still developing its business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. The skyrocketing cash burn up 101% year on year certainly tests our nerves. That sort of spending growth rate can't continue for very long before it causes balance sheet weakness, generally speaking. Clearly, however, the crucial factor is whether the company will grow its business going forward. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

How Hard Would It Be For Annexon To Raise More Cash For Growth?

While Annexon 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. Many companies end up issuing new shares to fund future 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.

Since it has a market capitalisation of US$84m, Annexon's US$108m in cash burn equates to about 129% of its market value. Given just how high that expenditure is, relative to the company's market value, we think there's an elevated risk of funding distress, and we would be very nervous about holding the stock.

So, Should We Worry About Annexon's Cash Burn?

On this analysis of Annexon's cash burn, we think its cash runway was reassuring, while its cash burn relative to its market cap has us a bit worried. Looking at the factors mentioned in this short report, we do think that its cash burn is a bit risky, and it does make us slightly nervous about the stock.
