Companies Like Aileron Therapeutics (NASDAQ:ALRN) Could Be Quite Risky

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 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 the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.

Given this risk, we thought we'd take a look at whether Aileron Therapeutics (NASDAQ:ALRN) 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. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

When Might Aileron Therapeutics Run Out Of Money?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. When Aileron Therapeutics last reported its balance sheet in June 2022, it had zero debt and cash worth US$32m. Looking at the last year, the company burnt through US$27m. Therefore, from June 2022 it had roughly 14 months of cash runway. That's not too bad, but it's fair to say the end of the cash runway is in sight, unless cash burn reduces drastically. You can see how its cash balance has changed over time in the image below.

How Is Aileron Therapeutics' Cash Burn Changing Over Time?

Because Aileron Therapeutics isn't currently generating revenue, we consider it an early-stage 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 34%, 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. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

Can Aileron Therapeutics Raise More Cash Easily?

While Aileron 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. 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. 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.

Aileron Therapeutics has a market capitalisation of US$21m and burnt through US$27m last year, which is 130% of the company's market value. Given just how high that expenditure is, relative to the company's market value, we think there's an elevated risk of funding distress, and we would be very nervous about holding the stock.

How Risky Is Aileron Therapeutics' Cash Burn Situation?

On this analysis of Aileron Therapeutics' cash burn, we think its cash runway was reassuring, while its cash burn relative to its market cap has us a bit worried. After looking at that range of measures, we think shareholders should be extremely attentive to how the company is using its cash, as the cash burn makes us uncomfortable.
