We can readily understand why investors are attracted to unprofitable companies. 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 Allogene Therapeutics (NASDAQ:ALLO) 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. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

When Might Allogene Therapeutics Run Out Of Money?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at June 2023, Allogene Therapeutics had cash of US$492m and no debt. Importantly, its cash burn was US$241m over the trailing twelve months. Therefore, from June 2023 it had 2.0 years of cash runway. 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 Allogene Therapeutics' Cash Burn Changing Over Time?

Whilst it's great to see that Allogene Therapeutics has already begun generating revenue from operations, last year it only produced US$192k, so we don't think it is generating significant revenue, at this point. Therefore, for the purposes of this analysis we'll focus on how the cash burn is tracking. With the cash burn rate up 14% in the last year, it seems that the company is ratcheting up investment in the business over time. That's not necessarily a bad thing, but investors should be mindful of the fact that will shorten the cash runway. 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 Allogene Therapeutics Raise More Cash Easily?

While Allogene Therapeutics 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 comparing a company's annual cash burn to its total market capitalisation, we can estimate roughly how many shares it would have to issue in order to run the company for another year (at the same burn rate).

Since it has a market capitalisation of US$466m, Allogene Therapeutics' US$241m in cash burn equates to about 52% of its market value. From this perspective, it seems that the company spent a huge amount relative to its market value, and we'd be very wary of a painful capital raising.

So, Should We Worry About Allogene Therapeutics' Cash Burn?

On this analysis of Allogene Therapeutics' cash burn, we think its cash runway was reassuring, while its cash burn relative to its market cap 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. Taking a deeper dive, we've spotted 3 warning signs for Allogene Therapeutics you should be aware of, and 1 of them shouldn't be ignored.
