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 software-as-a-service business Salesforce.com lost money for years while it grew recurring revenue, if you held shares since 2005, you'd have done very well indeed. But the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.

So, the natural question for Surrozen (NASDAQ:SRZN) shareholders is whether they should be concerned by its rate of cash burn. In this article, we define cash burn as its annual (negative) free cash flow, which is the amount of money a company spends each year to fund its growth. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

When Might Surrozen Run Out Of Money?

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. When Surrozen last reported its September 2024 balance sheet in November 2024, it had zero debt and cash worth US$31m. Importantly, its cash burn was US$28m over the trailing twelve months. Therefore, from September 2024 it had roughly 13 months of cash runway. While that cash runway isn't too concerning, sensible holders would be peering into the distance, and considering what happens if the company runs out of cash. Depicted below, you can see how its cash holdings have changed over time.

How Well Is Surrozen Growing?

On balance, we think it's mildly positive that Surrozen trimmed its cash burn by 16% over the last twelve months. But the revenue dip of 20% in the same period was a bit concerning. Considering both these factors, we're not particularly excited by its growth profile. 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 Surrozen Raise Cash?

While Surrozen seems to be in a fairly good position, it's still worth considering how easily it could raise more cash, even just to fuel faster growth. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. 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.

Since it has a market capitalisation of US$39m, Surrozen's US$28m in cash burn equates to about 72% of its market value. Given how large that cash burn is, relative to the market value of the entire company, we'd consider it to be a high risk stock, with the real possibility of extreme dilution.

Is Surrozen's Cash Burn A Worry?

On this analysis of Surrozen's cash burn, we think its cash burn reduction 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.
