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. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

So should Pluristem Therapeutics (NASDAQ:PSTI) shareholders be worried about its cash burn? In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

Does Pluristem Therapeutics 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. When Pluristem Therapeutics last reported its balance sheet in December 2020, it had zero debt and cash worth US$43m. Looking at the last year, the company burnt through US$27m. Therefore, from December 2020 it had roughly 19 months of cash runway. Importantly, analysts think that Pluristem Therapeutics will reach cashflow breakeven in 4 years. Essentially, that means the company will either reduce its cash burn, or else require more cash. You can see how its cash balance has changed over time in the image below.

How Is Pluristem Therapeutics' Cash Burn Changing Over Time?

Because Pluristem Therapeutics isn't currently generating revenue, we consider it an early-stage 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 2.9%, 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. 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 Hard Would It Be For Pluristem Therapeutics To Raise More Cash For Growth?

Since its cash burn is increasing (albeit only slightly), Pluristem Therapeutics shareholders should still be mindful of the possibility it will require more cash in the future. Companies can raise capital through either debt or equity. Many companies end up issuing new shares to fund future 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).
