Here's Why We're Watching Zelluna's (OB:ZLNA) Cash Burn Situation
Just because a business does not make any money, does not mean that the stock will go down. 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. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.
So should Zelluna (OB:ZLNA) shareholders 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.
How Long Is Zelluna's 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. As at June 2026, Zelluna had cash of kr86m and no debt. Importantly, its cash burn was kr102m over the trailing twelve months. That means it had a cash runway of around 10 months as of June 2026. That's quite a short cash runway, indicating the company must either reduce its annual cash burn or replenish its cash. Depicted below, you can see how its cash holdings have changed over time.

How Is Zelluna's Cash Burn Changing Over Time?
Because Zelluna isn't currently generating revenue, we consider it an early-stage 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. Given the length of the cash runway, we'd interpret the 27% reduction in cash burn, in twelve months, as prudent if not necessary for capital preservation. Zelluna makes us a little nervous due to its lack of substantial operating revenue. We prefer most of the stocks on this list of stocks that analysts expect to grow.
Can Zelluna Raise More Cash Easily?
Even though it has reduced its cash burn recently, shareholders should still consider how easy it would be for Zelluna to raise more cash in the future. Companies can raise capital through either debt or equity. Commonly, a business will sell new shares in itself to raise cash and drive 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.
Zelluna's cash burn of kr102m is about 14% of its kr738m market capitalisation. Given that situation, it's fair to say the company wouldn't have much trouble raising more cash for growth, but shareholders would be somewhat diluted.
How Risky Is Zelluna's Cash Burn Situation?
On this analysis of Zelluna's cash burn, we think its cash burn reduction was reassuring, while its cash runway has us a bit worried.
