Here's Why We're Not Too Worried About Aura Biosciences' (NASDAQ:AURA) Cash Burn Situation

We can readily understand why investors are attracted to unprofitable companies. 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 Aura Biosciences (NASDAQ:AURA) 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. Let's start with an examination of the business' cash, relative to its cash burn.

Does Aura Biosciences Have A Long 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. As at June 2023, Aura Biosciences had cash of US$162m and no debt. Importantly, its cash burn was US$61m over the trailing twelve months. So it had a cash runway of about 2.7 years from June 2023. That's decent, giving the company a couple years to develop its business. 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. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. With the cash burn rate up 24% 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. 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?

While Aura Biosciences 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. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. Many companies end up issuing new shares to fund future 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.

Aura Biosciences' cash burn of US$61m is about 15% of its US$392m market capitalisation. As a result, we'd venture that the company could raise more cash for growth without much trouble, albeit at the cost of some dilution.
