We can readily understand why investors are attracted to unprofitable companies. 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 the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.

Given this risk, we thought we'd take a look at whether Vivani Medical (NASDAQ:VANI) shareholders should 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'.

How Long Is Vivani Medical's Cash Runway?

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 Vivani Medical last reported its March 2024 balance sheet in May 2024, it had zero debt and cash worth US$30m. Looking at the last year, the company burnt through US$22m. So it had a cash runway of approximately 16 months from March 2024. While that cash runway isn't too concerning, sensible holders would be peering into the distance, and considering what happens if the company runs out of cash. You can see how its cash balance has changed over time in the image below.

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

Vivani Medical didn't record any revenue over the last year, indicating that it's an early stage company still developing its business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. As it happens, the company's cash burn reduced by 2.8% over the last year, which suggests that management are maintaining a fairly steady rate of business development, albeit with a slight decrease in spending. 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.

How Easily Can Vivani Medical Raise Cash?

While Vivani 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. 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 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).

Vivani Medical has a market capitalisation of US$64m and burnt through US$22m last year, which is 35% of the company's market value. That's fairly notable cash burn, so if the company had to sell shares to cover the cost of another year's operations, shareholders would suffer some costly dilution.

Is Vivani Medical's Cash Burn A Worry?

On this analysis of Vivani Medical's cash burn, we think its cash runway was reassuring, while its cash burn relative to its market cap has us a bit worried.
