Just because a business does not make any money, does not mean that the stock will go down. 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. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

So should enVVeno Medical (NASDAQ:NVNO) shareholders be worried about its cash burn? For the purpose of this article, we'll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow). Let's start with an examination of the business' cash, relative to its cash burn.

When Might enVVeno Medical Run Out Of Money?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at March 2025, enVVeno Medical had cash of US$39m and no debt. Looking at the last year, the company burnt through US$17m. So it had a cash runway of about 2.2 years from March 2025. Arguably, that's a prudent and sensible length of runway to have. Depicted below, you can see how its cash holdings have changed over time.

How Is enVVeno Medical's Cash Burn Changing Over Time?

enVVeno Medical 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. It seems likely that the business is content with its current spending, as the cash burn rate stayed steady over the last twelve months. 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.

How Hard Would It Be For enVVeno Medical To Raise More Cash For Growth?

While enVVeno Medical 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. Commonly, a business will sell new shares in itself to raise cash and drive 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).

Since it has a market capitalisation of US$75m, enVVeno Medical's US$17m in cash burn equates to about 23% of its market value. That's not insignificant, and if the company had to sell enough shares to fund another year's growth at the current share price, you'd likely witness fairly costly dilution.

So, Should We Worry About enVVeno Medical's Cash Burn?

Even though its cash burn relative to its market cap makes us a little nervous, we are compelled to mention that we thought enVVeno Medical's cash runway was relatively promising. 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 enVVeno Medical's situation.
