Just because a business does not make any money, does not mean that the stock will go down. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

Given this risk, we thought we'd take a look at whether Conexeu Sciences (NASDAQ:CNXU) shareholders should be worried about its cash burn. For the purposes of this article, cash burn is the annual rate at which an unprofitable company spends cash to fund its growth; its negative free cash flow. Let's start with an examination of the business' cash, relative to its cash burn.

When Might Conexeu Sciences Run Out Of Money?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at April 2026, Conexeu Sciences had cash of US$6.8m and such minimal debt that we can ignore it for the purposes of this analysis. In the last year, its cash burn was US$4.4m. So it had a cash runway of approximately 19 months from April 2026. 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 Is Conexeu Sciences' Cash Burn Changing Over Time?

Conexeu Sciences didn't record any revenue over the last year, indicating that it's an early stage company still developing its business. So while we can't look to sales to understand growth, we can look at how the cash burn is changing to understand how expenditure is trending over time. Its cash burn positively exploded in the last year, up 333%. With that kind of spending growth its cash runway will shorten quickly, as it simultaneously uses its cash while increasing the burn rate. 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.

Can Conexeu Sciences Raise More Cash Easily?

Given its cash burn trajectory, Conexeu Sciences shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. 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.

Conexeu Sciences has a market capitalisation of US$238m and burnt through US$4.4m last year, which is 1.8% of the company's market value. That means it could easily issue a few shares to fund more growth, and might well be in a position to borrow cheaply.

How Risky Is Conexeu Sciences' Cash Burn Situation?

On this analysis of Conexeu Sciences' cash burn, we think its cash burn relative to its market cap was reassuring, while its increasing cash burn has us a bit worried. While we're the kind of investors who are always a bit concerned about the risks involved with cash burning companies, the metrics we have discussed in this article leave us relatively comfortable about Conexeu Sciences' situation.
