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.

So should Unity Biotechnology (NASDAQ:UBX) shareholders be worried about its 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). We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

Does Unity Biotechnology 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 March 2024, Unity Biotechnology had cash of US$36m and no debt. Looking at the last year, the company burnt through US$31m. Therefore, from March 2024 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. Depicted below, you can see how its cash holdings have changed over time.

How Is Unity Biotechnology's Cash Burn Changing Over Time?

Unity Biotechnology 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. Even though it doesn't get us excited, the 37% reduction in cash burn year on year does suggest the company can continue operating for quite some time. 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.

How Hard Would It Be For Unity Biotechnology 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 Unity Biotechnology to raise more cash in the future. Companies can raise capital through either debt or equity. 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 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).

Unity Biotechnology has a market capitalisation of US$22m and burnt through US$31m last year, which is 139% 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 Unity Biotechnology's Cash Burn Situation?

Even though its cash burn relative to its market cap makes us a little nervous, we are compelled to mention that we thought Unity Biotechnology's cash burn reduction was relatively promising. Considering all the measures mentioned in this report, we reckon that its cash burn is fairly risky, and if we held shares we'd be watching like a hawk for any deterioration. On another note, Unity Biotechnology has 4 warning signs (and 1 which can't be ignored) we think you should know about.
