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 while the successes are well known, investors should not ignore the very many unprofitable companies that simply burn through all their cash and collapse.

So should Vivani Medical (NASDAQ:VANI) shareholders be worried about its cash burn? In this article, we define cash burn as its annual (negative) free cash flow, which is the amount of money a company spends each year to fund its growth. First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

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. In March 2026, Vivani Medical had US$20m in cash, and was debt-free. In the last year, its cash burn was US$27m. That means it had a cash runway of around 9 months as of March 2026. That's quite a short cash runway, indicating the company must either reduce its annual cash burn or replenish its cash. The image below shows how its cash balance has been changing over the last few years.

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. Over the last year its cash burn actually increased by 22%, which suggests that management are increasing investment in future growth, but not too quickly. That's not necessarily a bad thing, but investors should be mindful of the fact that will shorten the cash runway. 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?

Given its cash burn trajectory, Vivani Medical shareholders should already be thinking about how easy it might be for it to raise further cash in the future. Companies can raise capital through either debt or equity. Many companies end up issuing new shares to fund future 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.

Since it has a market capitalisation of US$106m, Vivani Medical's US$27m in cash burn equates to about 25% of its 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?

Vivani Medical is not in a great position when it comes to its cash burn situation. Although we can understand if some shareholders find its cash burn relative to its market cap acceptable, we can't ignore the fact that we consider its cash runway to be downright troublesome. After looking at that range of measures, we think shareholders should be extremely attentive to how the company is using its cash, as the cash burn makes us uncomfortable.
