There's no doubt that money can be made by owning shares of unprofitable businesses. 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. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.
So should Bicycle Therapeutics (NASDAQ:BCYC) 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'.
A company's cash runway is the amount of time it would take to burn through its cash reserves at its current cash burn rate. In June 2026, Bicycle Therapeutics had US$510m in cash, and was debt-free. In the last year, its cash burn was US$208m. Therefore, from June 2026 it had 2.4 years of cash runway. Arguably, that's a prudent and sensible length of runway to have. You can see how its cash balance has changed over time in the image below.

In the last twelve months, Bicycle Therapeutics kept its cash burn steady. But the good news is that its operating revenue showed verdant growth, up 217%. We think it is growing rather well, upon reflection. 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.
There's no doubt Bicycle Therapeutics seems to be in a fairly good position, when it comes to managing its cash burn, but even if it's only hypothetical, it's always worth asking how easily it could raise more money to fund growth. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. 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.
Bicycle Therapeutics has a market capitalisation of US$252m and burnt through US$208m last year, which is 83% of the company's market value. That suggests the company may have some funding difficulties, and we'd be very wary of the stock.
On this analysis of Bicycle Therapeutics' cash burn, we think its revenue growth was reassuring, while its cash burn relative to its market cap has us a bit worried. We don't think its cash burn is particularly problematic, but after considering the range of factors in this article, we do think shareholders should be monitoring how it changes over time. Taking an in-depth view of risks, we've identified 2 warning signs for Bicycle Therapeutics that you should be aware of before investing.
