Here's Why We're Watching Purple Biotech's (TLV:PPBT) Cash Burn Situation

Just because a business does not make any money, does not mean that the stock will go down. 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.

Given this risk, we thought we'd take a look at whether Purple Biotech (TLV:PPBT) shareholders should be worried about its cash burn. For the purposes of this article, cash burn is the annual rate at which an unprofitable company spends cash to fund its growth; its negative free cash flow. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

How Long Is Purple Biotech's Cash Runway?

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. As at December 2022, Purple Biotech had cash of US$32m and no debt. Looking at the last year, the company burnt through US$17m. Therefore, from December 2022 it had roughly 23 months of cash runway. That's not too bad, but it's fair to say the end of the cash runway is in sight, unless cash burn reduces drastically. The image below shows how its cash balance has been changing over the last few years.

How Is Purple Biotech's Cash Burn Changing Over Time?

Because Purple Biotech isn't currently generating revenue, we consider it an early-stage 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. Over the last year its cash burn actually increased by 10%, which suggests that management are increasing investment in future growth, but not too quickly. 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. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

How Easily Can Purple Biotech Raise Cash?

Given its cash burn trajectory, Purple Biotech 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. 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.

Purple Biotech's cash burn of US$17m is about 41% of its US$41m market capitalisation. That's high expenditure relative to the value of the entire company, so if it does have to issue shares to fund more growth, that could end up really hurting shareholders returns (through significant dilution).

Is Purple Biotech's Cash Burn A Worry?

On this analysis of Purple Biotech's cash burn, we think its cash runway was reassuring, while its cash burn relative to its market cap has us a bit worried. We don't think its cash burn is particularly problematic, but after considering the range of factors in this article, we do think shareholders should be monitoring how it changes over time. On another note, Purple Biotech has 5 warning signs (and 3 which are a bit unpleasant) we think you should know about.
