We Think Aura Biosciences (NASDAQ:AURA) Can Afford To Drive Business Growth

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, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. 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 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. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

When Might Aura Biosciences Run Out Of Money?

You can calculate a company's cash runway by dividing the amount of cash it has by the rate at which it is spending that cash. In September 2024, Aura Biosciences had US$174m in cash, and was debt-free. In the last year, its cash burn was US$75m. So it had a cash runway of about 2.3 years from September 2024. 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. Over the last year its cash burn actually increased by 14%, which suggests that management are increasing investment in future growth, but not too quickly. However, the company's true cash runway will therefore be shorter than suggested above, if spending continues to increase. Clearly, however, the crucial factor is whether the company will grow its business going forward. So you might want to take a peek at how much the company is expected to grow in the next few years.

How Easily Can Aura Biosciences Raise Cash?

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. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. Commonly, a business will sell new shares in itself to raise cash and drive 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.

Aura Biosciences has a market capitalisation of US$395m and burnt through US$75m last year, which is 19% of the company's market value. 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.
