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. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?
So should InspireMD (NASDAQ:NSPR) shareholders be worried about its cash burn? In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. Let's start with an examination of the business' cash, relative to its cash burn.
A cash runway is defined as the length of time it would take a company to run out of money if it kept spending at its current rate of cash burn. When InspireMD last reported its June 2026 balance sheet in August 2026, it had zero debt and cash worth US$30m. In the last year, its cash burn was US$42m. Therefore, from June 2026 it had roughly 9 months of cash runway. To be frank, this kind of short runway puts us on edge, as it indicates the company must reduce its cash burn significantly, or else raise cash imminently. Depicted below, you can see how its cash holdings have changed over time.

Some investors might find it troubling that InspireMD is actually increasing its cash burn, which is up 36% in the last year. Having said that, it's revenue is up a very solid 53% in the last year, so there's plenty of reason to believe in the growth story. The company needs to keep up that growth, if it is to really please shareholders. It seems to be growing nicely. While the past is always worth studying, it is the future that matters most of all. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.
InspireMD seems to be in a fairly good position, in terms of cash burn, but we still think it's worthwhile considering how easily it could raise more money if it wanted to. 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 comparing a company's annual cash burn to its total market capitalisation, we can estimate roughly how many shares it would have to issue in order to run the company for another year (at the same burn rate).
InspireMD's cash burn of US$42m is about 132% of its US$32m market capitalisation. Given just how high that expenditure is, relative to the company's market value, we think there's an elevated risk of funding distress, and we would be very nervous about holding the stock.
On this analysis of InspireMD's cash burn, we think its revenue growth was reassuring, while its cash burn relative to its market cap has us a bit worried. Considering all the measures mentioned in this report, we reckon that its cash burn is fairly risky, and if we held shares we'd be watching like a hawk for any deterioration. Separately, we looked at different risks affecting the company and spotted 3 warning signs for InspireMD (of which 2 don't sit too well with us!) you should know about.
