We can readily understand why investors are attracted to unprofitable companies. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?

So, the natural question for Prothena (NASDAQ:PRTA) shareholders is whether they should be concerned by its rate of cash burn. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

How Long Is Prothena's Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. When Prothena last reported its balance sheet in December 2020, it had zero debt and cash worth US$295m. Looking at the last year, the company burnt through US$76m. So it had a cash runway of about 3.9 years from December 2020. Importantly, analysts think that Prothena will reach cashflow breakeven in 5 years. Essentially, that means the company will either reduce its cash burn, or else require more cash. Depicted below, you can see how its cash holdings have changed over time.

How Is Prothena's Cash Burn Changing Over Time?

Whilst it's great to see that Prothena has already begun generating revenue from operations, last year it only produced US$853k, so we don't think it is generating significant revenue, at this point. As a result, we think it's a bit early to focus on the revenue growth, so we'll limit ourselves to looking at how the cash burn is changing over time. Over the last year its cash burn actually increased by 42%, 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. 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 Easily Can Prothena Raise Cash?

Given its cash burn trajectory, Prothena shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. Companies can raise capital through either debt or equity. Commonly, a business will sell new shares in itself to raise cash and drive 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.

Prothena's cash burn of US$76m is about 8.3% of its US$912m market capitalisation. Given that is a rather small percentage, it would probably be really easy for the company to fund another year's growth by issuing some new shares to investors, or even by taking out a loan.

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

It may already be apparent to you that we're relatively comfortable with the way Prothena is burning through its cash. In particular, we think its cash runway stands out as evidence that the company is well on top of its spending. Although its increasing cash burn does give us reason for pause, the other metrics we discussed in this article form a positive picture overall. One real positive is that analysts are forecasting that the company will reach breakeven. Looking at all the measures in this article, together, we're not worried about its rate of cash burn; the company seems well on top of its medium-term spending needs.
