We can readily understand why investors are attracted to unprofitable companies. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

Given this risk, we thought we'd take a look at whether Jasper Therapeutics (NASDAQ:JSPR) 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'. First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

Does Jasper Therapeutics Have A Long Cash Runway?

A company's cash runway is the amount of time it would take to burn through its cash reserves at its current cash burn rate. As at September 2025, Jasper Therapeutics had cash of US$51m and no debt. Looking at the last year, the company burnt through US$77m. Therefore, from September 2025 it had roughly 8 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. The image below shows how its cash balance has been changing over the last few years.

How Is Jasper Therapeutics' Cash Burn Changing Over Time?

Jasper Therapeutics 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. With the cash burn rate up 31% in the last year, it seems that the company is ratcheting up investment in the business over time. However, the company's true cash runway will therefore be shorter than suggested above, if spending continues to increase. 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 Jasper Therapeutics To Raise More Cash For Growth?

Given its cash burn trajectory, Jasper Therapeutics 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. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund growth. We can compare a company's cash burn to its market capitalisation to get a sense for how many new shares a company would have to issue to fund one year's operations.

Since it has a market capitalisation of US$53m, Jasper Therapeutics' US$77m in cash burn equates to about 144% of its market value. Given just how high that expenditure is, relative to the company's market value, we think there's an elevated risk of funding distress, and we would be very nervous about holding the stock.

Is Jasper Therapeutics' Cash Burn A Worry?

As you can probably tell by now, we're rather concerned about Jasper Therapeutics' cash burn. Take, for example, its cash burn relative to its market cap, which suggests the company may have difficulty funding itself, in the future. And although we accept its increasing cash burn wasn't as worrying as its cash burn relative to its market cap, it was still a real negative; as indeed were all the factors we considered in this article. Once we consider the metrics mentioned in this article together, we're left with very little confidence in the company's ability to manage its cash burn, and we think it will probably need more money. On another note, we conducted an in-depth investigation of the company, and identified 7 warning signs for Jasper Therapeutics (4 are a bit unpleasant!) that you should be aware of before investing here.
