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. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

So, the natural question for 374Water (NASDAQ:SCWO) shareholders is whether they should be concerned by its rate of 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.

Does 374Water Have A Long Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at June 2024, 374Water had cash of US$5.1m and no debt. Importantly, its cash burn was US$9.6m over the trailing twelve months. That means it had a cash runway of around 6 months as of June 2024. 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 374Water's Cash Burn Changing Over Time?

In our view, 374Water doesn't yet produce significant amounts of operating revenue, since it reported just US$245k 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 6.5%, 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. 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.

How Hard Would It Be For 374Water To Raise More Cash For Growth?

Since its cash burn is increasing (albeit only slightly), 374Water shareholders should still be mindful of the possibility it will require more cash in the future. 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. 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$196m, 374Water's US$9.6m in cash burn equates to about 4.9% of its 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.

How Risky Is 374Water's Cash Burn Situation?

Even though its cash runway makes us a little nervous, we are compelled to mention that we thought 374Water's cash burn relative to its market cap was relatively promising. Summing up, we think the 374Water's cash burn is a risk, based on the factors we mentioned in this article.
