Companies Like Pulse Biosciences (NASDAQ:PLSE) 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. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

So, the natural question for Pulse Biosciences (NASDAQ:PLSE) shareholders is whether they should be concerned by its rate of 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). Let's start with an examination of the business' cash, relative to its cash burn.

Does Pulse Biosciences Have A Long Cash Runway?

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. Pulse Biosciences has such a small amount of debt that we'll set it aside, and focus on the US$29m in cash it held at December 2021. Looking at the last year, the company burnt through US$55m. That means it had a cash runway of around 6 months as of December 2021. 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. You can see how its cash balance has changed over time in the image below.

How Is Pulse Biosciences' Cash Burn Changing Over Time?

In our view, Pulse Biosciences doesn't yet produce significant amounts of operating revenue, since it reported just US$1.4m in the last twelve months. As a result, we think it's a bit early to focus on the revenue growth, so we'll limit ourselves to looking at how the cash burn is changing over time. During the last twelve months, its cash burn actually ramped up 52%. Oftentimes, increased cash burn simply means a company is accelerating its business development, but one should always be mindful that this causes the cash runway to shrink. 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 Easily Can Pulse Biosciences Raise Cash?

Given its cash burn trajectory, Pulse Biosciences 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. 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 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.

Pulse Biosciences' cash burn of US$55m is about 52% of its US$106m market capitalisation. 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).

Is Pulse Biosciences' Cash Burn A Worry?

As you can probably tell by now, we're rather concerned about Pulse Biosciences' cash burn. In particular, we think its cash runway suggests it isn't in a good position to keep funding growth. While not as bad as its cash runway, its increasing cash burn is also a concern, and considering everything mentioned above, we're struggling to find much to be optimistic about. After considering the data discussed in this article, we don't have a lot of confidence that its cash burn rate is prudent, as it seems like it might need more cash soon.
