Just because a business does not make any money, does not mean that the stock will go down. 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. But while the successes are well known, investors should not ignore the very many unprofitable companies that simply burn through all their cash and collapse.

Given this risk, we thought we'd take a look at whether 5E Advanced Materials (NASDAQ:FEAM) shareholders should be worried about its cash burn. For the purposes of this article, cash burn is the annual rate at which an unprofitable company spends cash to fund its growth; its negative free cash flow. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

Does 5E Advanced Materials Have A Long Cash Runway?

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. In March 2026, 5E Advanced Materials had US$25m in cash, and was debt-free. Importantly, its cash burn was US$28m over the trailing twelve months. Therefore, from March 2026 it had roughly 11 months of cash runway. Notably, analysts forecast that 5E Advanced Materials will break even (at a free cash flow level) in about 4 years. That means unless the company reduces its cash burn quickly, it may well look to raise more cash. You can see how its cash balance has changed over time in the image below.

How Is 5E Advanced Materials' Cash Burn Changing Over Time?

5E Advanced Materials 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. Over the last year its cash burn actually increased by 2.3%, 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. While the past is always worth studying, it is the future that matters most of all. So you might want to take a peek at how much the company is expected to grow in the next few years.

How Easily Can 5E Advanced Materials Raise Cash?

Since its cash burn is increasing (albeit only slightly), 5E Advanced Materials 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. Many companies end up issuing new shares to fund future 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.

5E Advanced Materials has a market capitalisation of US$77m and burnt through US$28m last year, which is 37% of the company's market value. That's not insignificant, and if the company had to sell enough shares to fund another year's growth at the current share price, you'd likely witness fairly costly dilution.

How Risky Is 5E Advanced Materials' Cash Burn Situation?

5E Advanced Materials is not in a great position when it comes to its cash burn situation. Although we can understand if some shareholders find its increasing cash burn acceptable, we can't ignore the fact that we consider its cash burn relative to its market cap to be downright troublesome. Shareholders can take heart from the fact that analysts are forecasting it will reach breakeven. Looking at the factors mentioned in this short report, we do think that its cash burn is a bit risky, and it does make us slightly nervous about the stock.
