We can readily understand why investors are attracted to unprofitable companies. 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.

So should Tenax Therapeutics (NASDAQ:TENX) shareholders 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'. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

How Long Is Tenax Therapeutics' Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. In June 2026, Tenax Therapeutics had US$118m in cash, and was debt-free. Looking at the last year, the company burnt through US$46m. Therefore, from June 2026 it had 2.6 years of cash runway. Notably, analysts forecast that Tenax Therapeutics will break even (at a free cash flow level) in about 4 years. Essentially, that means the company will either reduce its cash burn, or else require more cash. You can see how its cash balance has changed over time in the image below.

How Is Tenax Therapeutics' Cash Burn Changing Over Time?

Tenax Therapeutics 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. The skyrocketing cash burn up 132% year on year certainly tests our nerves. It's fair to say that sort of rate of increase cannot be maintained for very long, without putting pressure on the balance sheet. 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.

Can Tenax Therapeutics Raise More Cash Easily?

While Tenax Therapeutics 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. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. 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.

Tenax Therapeutics has a market capitalisation of US$770m and burnt through US$46m last year, which is 6.0% of the company's 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.

How Risky Is Tenax Therapeutics' Cash Burn Situation?

As you can probably tell by now, we're not too worried about Tenax Therapeutics' cash burn. In particular, we think its cash runway stands out as evidence that the company is well on top of its spending. While we must concede that its increasing cash burn is a bit worrying, the other factors mentioned in this article provide great comfort when it comes to the cash burn. Shareholders can take heart from the fact that analysts are forecasting it will reach breakeven. Considering all the factors discussed in this article, we're not overly concerned about the company's cash burn, although we do think shareholders should keep an eye on how it develops. On another note, Tenax Therapeutics has 5 warning signs (and 4 which are a bit unpleasant) we think you should know about.
