Even when a business is losing money, it's possible for shareholders to make money if they buy a good business at the right price. 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. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

So, the natural question for Aura Biosciences (NASDAQ:AURA) shareholders is whether they should be concerned by its rate of cash burn. For the purpose of this article, we'll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow). Let's start with an examination of the business' cash, relative to its cash burn.

How Long Is Aura Biosciences' Cash Runway?

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. In March 2024, Aura Biosciences had US$203m in cash, and was debt-free. Looking at the last year, the company burnt through US$73m. That means it had a cash runway of about 2.8 years as of March 2024. Arguably, that's a prudent and sensible length of runway to have. Depicted below, you can see how its cash holdings have changed over time.

How Is Aura Biosciences' Cash Burn Changing Over Time?

Aura Biosciences didn't record any revenue over the last year, indicating that it's an early stage company still developing its 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 29%, which suggests that management are increasing investment in future growth, but not too quickly. That's not necessarily a bad thing, but investors should be mindful of the fact that will shorten the cash runway. 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 Aura Biosciences To Raise More Cash For Growth?

Given its cash burn trajectory, Aura Biosciences 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. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund 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.

Since it has a market capitalisation of US$367m, Aura Biosciences' US$73m in cash burn equates to about 20% of its market value. Given that situation, it's fair to say the company wouldn't have much trouble raising more cash for growth, but shareholders would be somewhat diluted.

How Risky Is Aura Biosciences' Cash Burn Situation?

On this analysis of Aura Biosciences' cash burn, we think its cash runway was reassuring, while its increasing cash burn has us a bit worried. Considering all the factors discussed in this article, we're not overly concerned about the company's cash burn, although we do think shareholders should keep an eye on how it develops.
