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. 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 TAO Synergies (NASDAQ:TAOX) 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). Let's start with an examination of the business' cash, relative to its cash burn.

When Might TAO Synergies Run Out Of Money?

A cash runway is defined as the length of time it would take a company to run out of money if it kept spending at its current rate of cash burn. As at March 2026, TAO Synergies had cash of US$3.6m and no debt. Looking at the last year, the company burnt through US$6.1m. That means it had a cash runway of around 7 months as of March 2026. 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. You can see how its cash balance has changed over time in the image below.

How Is TAO Synergies' Cash Burn Changing Over Time?

In our view, TAO Synergies doesn't yet produce significant amounts of operating revenue, since it reported just US$688k 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 20%, which suggests that management are increasing investment in future growth, but not too quickly. However, the company's true cash runway will therefore be shorter than suggested above, if spending continues to increase. Admittedly, we're a bit cautious of TAO Synergies 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 Easily Can TAO Synergies Raise Cash?

Since its cash burn is moving in the wrong direction, TAO Synergies shareholders may wish to think ahead to when the company may need to raise more cash. 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. 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).

Since it has a market capitalisation of US$24m, TAO Synergies' US$6.1m in cash burn equates to about 25% 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.

So, Should We Worry About TAO Synergies' Cash Burn?

We must admit that we don't think TAO Synergies is in a very strong position, when it comes to its cash burn. While its cash burn relative to its market cap wasn't too bad, its cash runway does leave us rather nervous. After looking at that range of measures, we think shareholders should be extremely attentive to how the company is using its cash, as the cash burn makes us uncomfortable.
