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 Allakos (NASDAQ:ALLK) shareholders should be worried about its cash burn. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. Let's start with an examination of the business' cash, relative to its cash burn.

When Might Allakos 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 Allakos last reported its balance sheet in September 2020, it had zero debt and cash worth US$420m. Importantly, its cash burn was US$99m over the trailing twelve months. So it had a cash runway of about 4.2 years from September 2020. Notably, analysts forecast that Allakos will break even (at a free cash flow level) in about 5 years. That means unless the company reduces its cash burn quickly, it may well look to raise more cash. You can see how its cash balance has changed over time in the image below.

How Is Allakos' Cash Burn Changing Over Time?

Because Allakos 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. During the last twelve months, its cash burn actually ramped up 65%. Oftentimes, increased cash burn simply means a company is accelerating its business development, but one should always be mindful that this causes the cash runway to shrink. 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.

Can Allakos Raise More Cash Easily?

While Allakos 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. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund 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.

Allakos' cash burn of US$99m is about 1.5% of its US$6.4b market capitalisation. That means it could easily issue a few shares to fund more growth, and might well be in a position to borrow cheaply.

Is Allakos' Cash Burn A Worry?

It may already be apparent to you that we're relatively comfortable with the way Allakos is burning through its cash. For example, we think its cash runway suggests that the company is on a good path. Although its increasing cash burn does give us reason for pause, the other metrics we discussed in this article form a positive picture overall. Shareholders can take heart from the fact that analysts are forecasting it 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. Taking a deeper dive, we've spotted 3 warning signs for Allakos you should be aware of, and 1 of them is significant.
