Here's Why We're Watching Heat Biologics' (NASDAQ:HTBX) Cash Burn Situation

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

Given this risk, we thought we'd take a look at whether Heat Biologics (NASDAQ:HTBX) 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. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

How Long Is Heat Biologics' 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 2021, Heat Biologics had cash of US$109m and no debt. Looking at the last year, the company burnt through US$35m. Therefore, from September 2021 it had 3.1 years of cash runway. There's no doubt that this is a reassuringly long runway. The image below shows how its cash balance has been changing over the last few years.

How Well Is Heat Biologics Growing?

Notably, Heat Biologics actually ramped up its cash burn very hard and fast in the last year, by 112%, signifying heavy investment in the business. That's pretty alarming given that operating revenue dropped 52% over the last year, though the business is likely attempting a strategic pivot. Considering these two factors together makes us nervous about the direction the company seems to be heading. 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 Hard Would It Be For Heat Biologics To Raise More Cash For Growth?

Heat Biologics seems to be in a fairly good position, in terms of cash burn, but we still think it's worthwhile considering how easily it could raise more money if it wanted to. Companies can raise capital through either debt or equity. 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.

Heat Biologics' cash burn of US$35m is about 39% of its US$88m 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 Heat Biologics' Cash Burn?

On this analysis of Heat Biologics' cash burn, we think its cash runway was reassuring, while its falling revenue 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.
