There's no doubt that money can be made by owning shares of unprofitable businesses. 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.

Given this risk, we thought we'd take a look at whether BlinkLab (ASX:BB1) shareholders should 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'. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

Does BlinkLab 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. When BlinkLab last reported its December 2024 balance sheet in February 2025, it had zero debt and cash worth AU$4.4m. Looking at the last year, the company burnt through AU$3.1m. That means it had a cash runway of around 17 months as of December 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 BlinkLab's Cash Burn Changing Over Time?

While BlinkLab did record statutory revenue of AU$195k over the last year, it didn't have any revenue from operations. That means we consider it a pre-revenue business, and we will focus our growth analysis on cash burn, for now. Remarkably, it actually increased its cash burn by 423% in the last year. With that kind of spending growth its cash runway will shorten quickly, as it simultaneously uses its cash while increasing the burn rate. 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 .

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

While BlinkLab does have a solid cash runway, its cash burn trajectory may have some shareholders thinking ahead to when the company may need to raise more cash. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. 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).

BlinkLab has a market capitalisation of AU$34m and burnt through AU$3.1m last year, which is 9.3% of the company's market value. That's a low proportion, so we figure the company would be able to raise more cash to fund growth, with a little dilution, or even to simply borrow some money.

So, Should We Worry About BlinkLab's Cash Burn?

Even though its increasing cash burn makes us a little nervous, we are compelled to mention that we thought BlinkLab's cash burn relative to its market cap was relatively promising. Even though we don't think it has a problem with its cash burn, the analysis we've done in this article does suggest that shareholders should give some careful thought to the potential cost of raising more money in the future.
