Just because a business does not make any money, does not mean that the stock will go down. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

So, the natural question for Research Frontiers (NASDAQ:REFR) shareholders is whether they should be concerned by its rate of 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. Let's start with an examination of the business' cash, relative to its cash burn.

Does Research Frontiers Have A Long Cash Runway?

You can calculate a company's cash runway by dividing the amount of cash it has by the rate at which it is spending that cash. As at March 2026, Research Frontiers had cash of US$1.3m and no debt. In the last year, its cash burn was US$1.4m. Therefore, from March 2026 it had roughly 11 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.

How Is Research Frontiers' Cash Burn Changing Over Time?

In our view, Research Frontiers doesn't yet produce significant amounts of operating revenue, since it reported just US$698k in the last twelve months. As a result, we think it's a bit early to focus on the revenue growth, so we'll limit ourselves to looking at how the cash burn is changing over time. Over the last year its cash burn actually increased by 39%, 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. Admittedly, we're a bit cautious of Research Frontiers due to its lack of significant operating revenues. We prefer most of the stocks on this list of stocks that analysts expect to grow.

How Hard Would It Be For Research Frontiers To Raise More Cash For Growth?

Given its cash burn trajectory, Research Frontiers shareholders should already be thinking about how easy it might be for it to raise further cash in the future. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. 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$25m, Research Frontiers' US$1.4m in cash burn equates to about 5.9% of its market value. Given that is a rather small percentage, it would probably be really easy for the company to fund another year's growth by issuing some new shares to investors, or even by taking out a loan.

Is Research Frontiers' Cash Burn A Worry?

On this analysis of Research Frontiers' cash burn, we think its cash burn relative to its market cap was reassuring, while its increasing cash burn 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. On another note, Research Frontiers has 3 warning signs (and 2 which don't sit too well with us) we think you should know about.
