Here's Why We're A Bit Worried About Microbot Medical's (NASDAQ:MBOT) 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. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

Given this risk, we thought we'd take a look at whether Microbot Medical (NASDAQ:MBOT) shareholders should 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'. Let's start with an examination of the business' cash, relative to its cash burn.

Does Microbot Medical Have A Long Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. When Microbot Medical last reported its balance sheet in September 2022, it had zero debt and cash worth US$6.3m. In the last year, its cash burn was US$12m. Therefore, from September 2022 it had roughly 6 months of cash runway. To be frank, this kind of short runway puts us on edge, as it indicates the company must reduce its cash burn significantly, or else raise cash imminently. Depicted below, you can see how its cash holdings have changed over time.

How Is Microbot Medical's Cash Burn Changing Over Time?

Microbot Medical 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 45%, 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.

How Hard Would It Be For Microbot Medical To Raise More Cash For Growth?

Given its cash burn trajectory, Microbot Medical shareholders should already be thinking about how easy it might be for it to raise further 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 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.

Microbot Medical has a market capitalisation of US$26m and burnt through US$12m last year, which is 47% of the company's market value. That's high expenditure relative to the value of the entire company, so if it does have to issue shares to fund more growth, that could end up really hurting shareholders returns (through significant dilution).

So, Should We Worry About Microbot Medical's Cash Burn?

We must admit that we don't think Microbot Medical is in a very strong position, when it comes to its cash burn. While its increasing cash burn wasn't too bad, its cash runway does leave us rather nervous. Once we consider the metrics mentioned in this article together, we're left with very little confidence in the company's ability to manage its cash burn, and we think it will probably need more money. On another note, Microbot Medical has 5 warning signs (and 3 which are a bit concerning) we think you should know about.
