There's no doubt that money can be made by owning shares of unprofitable businesses. For example, although Amazon.com made losses for many years after listing, if you had bought and held the shares since 1999, you would have made a fortune. 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 Immix Biopharma (NASDAQ:IMMX) shareholders should be worried about its cash burn. For the purpose of this article, we'll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow). We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

When Might Immix Biopharma Run Out Of Money?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at June 2025, Immix Biopharma had cash of US$12m and no debt. Looking at the last year, the company burnt through US$13m. Therefore, from June 2025 it had roughly 10 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 Immix Biopharma's Cash Burn Changing Over Time?

Immix Biopharma 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 12% over the last year, which suggests that management may be mindful of the risks of their depleting cash reserves. Clearly, however, the crucial factor is whether the company will grow its business going forward. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

Can Immix Biopharma Raise More Cash Easily?

While Immix Biopharma 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. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. Commonly, a business will sell new shares in itself to raise cash and drive 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$67m, Immix Biopharma's US$13m in cash burn equates to about 20% 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.
