Here's Why We're Watching Achilles Therapeutics' (NASDAQ:ACHL) Cash Burn Situation

There's no doubt that money can be made by owning shares of unprofitable businesses. 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.

So should Achilles Therapeutics (NASDAQ:ACHL) shareholders 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 Achilles Therapeutics Run Out Of Money?

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. When Achilles Therapeutics last reported its balance sheet in September 2022, it had zero debt and cash worth US$180m. Importantly, its cash burn was US$62m over the trailing twelve months. That means it had a cash runway of about 2.9 years as of September 2022. That's decent, giving the company a couple years to develop its business. The image below shows how its cash balance has been changing over the last few years.

How Is Achilles Therapeutics' Cash Burn Changing Over Time?

Achilles Therapeutics didn't record any revenue over the last year, indicating that it's an early stage company still developing its business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. As it happens, the company's cash burn reduced by 4.6% over the last year, which suggests that management are maintaining a fairly steady rate of business development, albeit with a slight decrease in spending. 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 Hard Would It Be For Achilles Therapeutics To Raise More Cash For Growth?

Even though it has reduced its cash burn recently, shareholders should still consider how easy it would be for Achilles Therapeutics to raise more cash in the future. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. Commonly, a business will sell new shares in itself to raise cash and drive 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).

Achilles Therapeutics has a market capitalisation of US$79m and burnt through US$62m last year, which is 79% of the company's market value. Given how large that cash burn is, relative to the market value of the entire company, we'd consider it to be a high risk stock, with the real possibility of extreme dilution.
