There's no doubt that money can be made by owning shares of unprofitable businesses. 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 Acrivon Therapeutics (NASDAQ:ACRV) 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. The first step is to compare its cash burn with its cash reserves, to give us its '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. In March 2026, Acrivon Therapeutics had US$98m in cash, and was debt-free. In the last year, its cash burn was US$66m. That means it had a cash runway of around 18 months as of March 2026. That's not too bad, but it's fair to say the end of the cash runway is in sight, unless cash burn reduces drastically. The image below shows how its cash balance has been changing over the last few years.

Acrivon Therapeutics 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. With cash burn dropping by 5.5% it seems management feel the company is spending enough to advance its business plans at an appropriate pace. While the past is always worth studying, it is the future that matters most of all. So you might want to take a peek at how much the company is expected to grow in the next few years.
While Acrivon Therapeutics is showing a solid reduction in its cash burn, it's still worth considering how easily it could raise more cash, even just to fuel faster growth. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. Many companies end up issuing new shares to fund future 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.
Acrivon Therapeutics' cash burn of US$66m is about 76% of its US$88m market capitalisation. 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.
On this analysis of Acrivon Therapeutics' cash burn, we think its cash runway was reassuring, while its cash burn relative to its market cap has us a bit worried.
